Technical field the Present image is m-division multiplexing (mdcr), more specifically to a method and apparatus for performing voice communication and data exchange using a dedicated control channel.

The prior art Mobile communication system mdcr was developed taking into account the existing mobile communication standard, which basically provides voice communication in the IMT-2000 (international mobile telecommunications-2000), which allows us to support not only voice communication, but also high-speed transmission of packet data. System for mobile communications based on IMT-2000 allows us to provide high-quality services related to voice, moving images and search in the Internet. System for mobile communications mdcr has the communication channels between the base station and the terminal, and the communication channels are divided into direct communication channel passing from the base station to the terminal, and the reverse communication channel passing from the terminal to the base station.

Known communication system mdcr, although suitable for voice communication, however, is not suitable for transmitting data requiring high speed data transmission and voice communication quality. In order to perform various multimedia services, such as data exchange and voice communications is to use communication channels to service voice and data, in order to allocate channels dynamically to a user request.

When the channel traffic is divided into a main channel and an additional channel for maintenance of data exchange, main channel, which need to be maintained for the transmission of control information even in this state, when the base station does not support communication with mobile station (i.e. the terminal). Accordingly, the conventional system for mobile communications mdcr may be futile to expend resources communication channels.

In addition, the conventional system for mobile communications mdcr transmits a control message with a fixed frame size. Thus, although the system has a smaller amount of data transmitted to the control message, it should send data with a fixed size frame, which results in reduced bandwidth.

In addition to this known system for mobile communications mdcr transmits the bits of the reverse power control through direct primary channel. Therefore, even if the system has no user data to pass through the main channel, it should support the main channel for the reverse power control that affects the communication quality.

In normal snidely channel and a control channel. The generator control channel in the known mobile communication system mdcr only uses 10 bits per frame duration of 20 MS, as the input bits, and inserts into it a bit power control at a specific point in time. In this case, the message size is too small for effective management. In addition, since the bit power control is transmitted via the control channel, the system must support a control channel for power control even in the case when the system has no control message transfer.

Summary of the invention the present invention is to provide a method and device for transmitting/receiving speech and data communication systems mdcr.

Another object of the present invention is to provide device and method for transmitting/receiving control information during transmission/reception of voice and data using dedicated control channel in the communication system mdcr.

Also, the present invention is to create a device and method for transmitting/receiving control information during transmission/reception of voice and data using dedicated control channel in which the frame message has a structure, the present invention is to create a communication system mdcr to send alarm messages and error messages, control information using channels not busy.

In addition, the present invention is to create a communication system mdcr, in which the device postback enters the control signal power of the pilot channel signal, and transmits the control message using the selected control channel.

In order to solve the aforementioned problem, the present invention provides a communication system mdcr that includes a base station device and the terminal. The device of the base station has a generator forward link pilot signal to generate a pilot signal generator directly allocated control channel to generate the control message intended for direct dedicated control channel generator direct main channel to generate the speech signal and the generator direct additional channel to generate packet data.

A detailed description of the preferred embodiments
Description of the preferred embodiments of the present invention is given with reference to the drawings, in which identical reference positions indicated similar elements.

In the following description, numerous specific details, such as the length of the frame, the encoding speed and the number of data bits and symbols that are output from the respective generators of channels, are provided to illustrate the present invention. But experts it is clear that the present invention moneyhats for purposes of clarity of description.

In the description, the term "control message" refers to a message transmitted through a dedicated control channel; and messages that can be transmitted through the dedicated control channel may include various control messages (alarm L3), which are used in the frame of the CRP Protocol (radio channel) standard IS-95B, and the message DCP (control access to the transmission medium), which is a service control message packet data for allocation and deallocation of an additional channel.

In addition, the term "dedicated channel" that is used in the description refers to the exclusive channel for communication between the base station and the terminal, and is the antonym of the common channel. In the present invention the selected channel includes a dedicated control channel, extra channel, the fundamental channel and the reverse pilot channel signal. That is a direct dedicated channel is a combination of all the selected channels available for transmission of information from the base station to the terminal, and includes a straight main channel, direct channel and direct the dedicated control channel. In addition, the reverse dedicated channel javljaetsja, and includes a reverse channel, opposite the main channel, the reverse dedicated control channel and the reverse pilot channel signal.

In Fig. 1 shows a receiver-transmitter for a communication system mdcr, according to a variant implementation of the present invention, in which the respective channels and the respective channel of the receiving / transmitting device shown in relation to the transmitters.

In the base station controller 101 enables or disables the corresponding channel generators base station that manages communications physical layer, which are transmitted/received in the base station, and enables exchange of messages with top-level object. The generator 105 pilot channel generator 107 synchronal and generator 109 paging channel forming device for receiving a common channel information, which is used, in General, users in a single cell or many cells. The generator 103 a dedicated control channel generator 111 main channel generator 113 additional channel forming device to obtain information about the selected channel, which is allocated in a different way each user.

The generator 103 is allocated opravlyaushi control channel (PWOC), and transmits the processed control messages in the terminal. In the process, messages that are transmitted through direct dedicated control channel consists of various control messages (alarm L3), which are used in the frame of the CRP or standard IS-95B, and the message UDS, which is a utility managing message batch data for allocation and deallocation of an additional channel. When the auxiliary channel is not used, the control signal power can be transferred through a dedicated control channel. In this case, the control signal power can be included in the control message. In addition, the data rate that will be used by the base station and an additional channel, consistent with direct allocated managing channel. The generator 103 direct dedicated channel also issues a command to change the orthogonal code of the orthogonal code is used in the additional channel.

The generator 103 a dedicated control channel extends over the spectrum allocated to the control channel by assigning direct dedicated control channel is not used one of the orthogonal codes that have not been assigned to the generator 105 Cana the messages through a direct channel by adding the control message to the main channel, the transmission delay becomes too serious for high-speed communication packet data, and the quality of the main channel is also reduced. However, by allocating a dedicated control channel for a downlink channel to use message UDS system according to the present invention can provide high-speed packet data service, thereby improving the reception quality data of the main channel and the additional channel. Frame ASM can provide the service stream of eight-bit bytes (octets). CRP can be divided into transparent CRP and opaque CRP. Transparent CRP although not transmit again erroneously transmitted frame, but notifies you of the time and position of the erroneously transmitted frame is the top-level object. Opaque CRP provides a method for error correction.

The generator 105 of the pilot channel signal, processes the information, which is transmitted via the forward link pilot signal, and transmits the processed information to the terminal. Direct channel pilot signal transmits logic signals are all "0" and all "1". In this case, it is assumed that the pilot channel signal produces a logical signal "0". The pilot signal allows a target device to perform a quick first spectrum pilot signal using a specific orthogonal code channel pilot signal.

The generator 107 synchronal processes information, which is transmitted through direct synchronal, and transmits the processed information to the terminal. Information, which is transmitted through synchronal, allows the terminals located in the same cell, to perform temporary and frame synchronization. The generator 107 synchronal stretches along the spectrum information of synchronal by assigning specific orthogonal code for direct synchronal.

Generator 109 paging channel processing information, which is transmitted through direct paging channel, and transmits the processed information to the terminal. Information, which is transmitted through the paging channel, includes all the information that is required before establishing a communication channel. Generator 109 paging channel stretches on the spectrum of the signal direct paging channel by assigning one of the set of orthogonal codes for direct paging channel.

Generator 111 of the main channel processes information, which is transmitted through direct primary channel, and transmits the processed information to the terminal. Information, which is transmitted through direct primary channel, allamuchy various control messages (alarm L3), which is used in the standard IS-95B, and the signal power control in addition to the speech signal. Moreover, a signal transmitted through a straight main channel, may include the frame of the CRP and the message UDS if necessary.

The main channel has a data rate of 9.6 kbit/s or 14.4 kbit/s Sometimes requires that the main channel may have a variable bit rate, which is 4.8 kbps or 7.2 kbps totransfer rate, 2.4 kbit/s or 3.6 kbit/s transfer rate 1/4 and 1.2 kbit/s or 1.8 kbit/s transfer rate 1/8. In this case, it is necessary that the receiver can detect the change of speed of data transfer. Generator 111 direct main channel extends the range of the signal of the main channel by assigning the main channel is not used by one of the orthogonal codes that are not assigned to the generator 105 channel pilot signal generator 107 synchronal and generator 109 paging channel.

Generator 113 additional channel processes information, which is transmitted through the direct channel, and transmits the processed information to the terminal. Information, which is transmitted through direct additive is giving data over 9.6 kbit/sec Generator 113 additional channel has scheduled the transmission rate at which the base station communicates with the terminal to establish communication with each other at the speed of data transfer, which is determined in the base station. Generator 113 direct additional channel extends the range of the signal channel by assigning additional channel is not used by one of the orthogonal codes that are not assigned to the generator 113 additional channel, the generator 105 pilot channel generator 107 synchronal and generator 109 paging channel. In this case, the main channel and the additional channel are channels of traffic.

The adder 115 adds the transmission signals of channel I (in-phase channel), which are derived from the generator 103 a dedicated control channel generator 111 main channel generator 113 additional channel, and the transmission signals, which are output from the generator 105 channel pilot signal generator 107 clock generator 109 paging channel. The adder 117 produces the sum of signal transmission channel Q (quadrature channel), which are derived from the generator 103 a dedicated control channel generator 111 of the main channel is outputted from the adders 115 and 117, by multiplying the transmitted signals in the sequence spread spectrum. Extended spectrum signals is converted up in frequency to radio frequency and transmitted to the terminal. The receiver 121 converts the respective channel signals, which are received from a terminal via a reverse communication channel, the signal bandwidth of the video signal and narrows the spectrum of the converted channel signals by multiplying them by the sequence spread spectrum. In Fig. 1 not shown the detailed structure of the receivers of the backward channel.

The following describes the structure of a terminal, the controller 151 unlocks and locks the generator of the corresponding channel terminal, processes the message to the physical layer, which is transmitted/received in the terminal device, and performs communications with top-level object.

Generator 153 dedicated control channel handles different messages that will be transmitted through the reverse dedicated control channel and transmits the processed message to the base station. In the process the messages that are transmitted through the reverse dedicated control channel, are made up of different control messages (signala for the appointment and dismissal of the additional channel. Because the signal power is transmitted by using the pilot channel signal, a reverse dedicated control channel does not transmit the control signal power.

In addition, the generator 153 reverse dedicated control channel transmits a control message to negotiate the transmission speed of data that will be used in the additional channel with the base station. Generator 153 reverse dedicated control channel extends along the spectrum signals using a predetermined orthogonal code assigned to the respective channels, to classify the reverse communication channels. In this case, since the orthogonal code is used to classify channels, dedicated control channel, the pilot channel signal, the access channel, the main channel and the additional channel is used according to different orthogonal codes. All users share the same orthogonal codes for the same channels. For example, users distinguish a dedicated control channel using the same orthogonal code assigned to the reverse dedicated control channel.

Generator 153 reverse dedicated control channel transmits control who is using only 10 bits in a frame duration of 20 MS. However, in the embodiment of the present invention, the control information can be passed through more than 168 bits in a frame duration of 20 MS or by more than 24 bits in a frame duration of 5 MS, thus enabling efficient management. By setting the data transfer rate generator 153 reverse dedicated control channel 9.6 kbps, the performance degradation caused by the determination of the speed of data transmission is prevented, and the system does not require the use of a schema definition of the data rate, so the receiver can be simplified. In addition, having the same data rate as the basic data rate of 9.6 kbps speech signal generator 153 dedicated control channel can serve the same service area (i.e., coverage), as in normal voice communication services.

Generator 155 pilot signal, processes the information, which is transmitted through the reverse channel pilot signal, and transmits the processed information to the base station. Like the signal forward link pilot signal, a reverse pilot channel signal is used for rapid initial data collection and evaluation to the and capacity by adding a signal to control power to the pilot signal at a specific point in time. In the reverse channel signal power control is introduced in the channel, the pilot signal so that there is no need to use other channels for additional signal transmission power control. This reduces the ratio of the maximum to the average value, which leads to the expansion of the terminal.

Generator 157 channel access process information, which is transmitted via a reverse access channel and transmits the processed information to the base station. The message signal channel access consists of all information and control message terminal, which required the base station before assigning traffic channels.

Generator 159 main channel processes information, which is transmitted through the reverse main channel, and transmits the processed information to the base station. In the process information, which is transmitted through the reverse primary link is usually the speech signal. In addition, the information, which is transmitted through the reverse primary link may include various control messages (alarm L3), which are used in the standard IS-95B, in addition to the speech signal. In addition, the signal peredavaemye links information power control is passed to the pilot channel signal, and not in the main channel.

The main channel has a data rate of 9.6 kbit/s or 14.4 kbit/S. In some cases, it is necessary that the main channel had a variable speed transmission, which are equal to 4.8 kbps or 7.2 kbps totransfer rate, 2.4 kbit/s or 3.6 kbit/s transfer rate 1/4 and 1.2 kbit/s or 1.8 kbit/s transfer rate 1/8. In this case, it is necessary that the receiver can detect the change of speed of data transfer. Generator 159 opposite the main channel distinguishes between channels with the expansion of the spectrum of the signal of the main channel using orthogonal codes assigned to the respective channels, and distinguishes users by using PS-codes assigned to the appropriate users. In this case, since the orthogonal code is used for detection channels, the pilot channel signal, the access channel, dedicated control channel, the main channel and the secondary channel using different orthogonal codes, and all users share the same orthogonal codes for the same channels. For example, for recognition of the main channel, all users use the same orthogonal code.

Generator 161 to the al, and transmits the processed information to the base station. Information, which is transmitted through the reverse channel, includes a frame CRP and packet data. Generator 161 additional channel has a data rate of more than 9.6 kbit/S. in Addition, the generator 161 additional channel has scheduled the transmission rate at which the base station communicates with the terminal to establish communication with each other with the speed of data transfer, which is determined by the base station. Generator 161 reverse channel extends along the spectrum signals using a predetermined orthogonal code assigned to the respective channels for the classification of reverse communication channels. In this case, the main channel and the additional channel are channel traffic.

The adder 163 summarizes the signal transmission generated by the generator 153 dedicated control channel generator 155, the pilot signal. The adder 165 summarizes the signal transmission generated by the generator 157 access channel generator 159 main channel generator 161 additional channel. The range extender 167 extends over the spectrum of the signal transmission from the outputs of the adders 163 and 165 by multiplying the signal transmission region. The receiver 169 converts the respective channel signals from a base station in direct communication channel, the signal bandwidth of the video signal and narrows the spectrum of the converted signal channel is multiplied by the sequence spread spectrum. In Fig. 1 not shown the detailed structure of the channel receivers direct communication channel.

In the communication system mdcr (Fig.1), according to the present invention, a base station includes a controller 101 to control all channels, the generator 103 a dedicated control channel for processing signals that are passed to the appropriate channels, the generator 105 channel pilot signal generator 107 synchronal, generator 109 paging channel generator 111 main channel generator 113 additional channel. The terminal includes a controller 151, the generator 153 dedicated control channel generator 155 channel pilot signal generator 157 access channel generator 159 main channel generator 161 of the main channel. As for the outputs of the generators of the respective channels, the outputs of the generator 103 a dedicated control channel generator 111 main channel generator 113 additional channels are divided into part I-ka is combined 109 paging channel to produce a separate component of the channel, for example, component (I-channel.

In contrast to the channels of the base station, the terminal channels form at the output of a separate component of the channel. That is, the adder 163 sums the output signals of the generator 153 dedicated control channel generator 155 channel pilot signal and supplies them to the output signals of the I-channel device in the expansion of the range of 167. The adder 165 sums the output signals of the generators 157, 159 and 161 other channels and delivers them to the output signals in the Q-channel expansion unit spectrum 167. Generator 157 access channel produces its output signal to the destination channel traffic. Therefore, when using the access channel, the output signal generator 155 channel pilot signal in the I channel, and the output signal generator 157 channel access is introduced in the Q-channel.

The following describes embodiments of the present invention with reference to Fig. 2-12 for generators of the respective channels and, in addition, describes the work of the respective channels with reference to Fig.1 and 14-21 procedures for performing various services.

In Fig. 2A and 2B depicts a detailed block diagram of the generator 103 direct dedicated control channel. The generator 103 direct dedicated control channel uses the frame with perennia the first frame, and in Fig.2B shows the generator 103 direct dedicated control channel, which receives the control message to the second frame. In this case, the duration of the first and second frames is 5 MS and 20 MS, respectively. In addition, the 5 MS frame (first frame) consists of 24 bits, and the 20 MS frame (second frame) consists of 172 bits. In addition, the encoding speed is equal to.

In Fig.2A generator 202 ICC (CRC) produces a 16-bit ICC, puts it with the received 24-bit control data frame is 5 MS, and thus displays the 40-bit data. The generator 204 target bit produces terminal 8 bits to indicate the end of the control message frame is 5 MS, and adds the generated target bits to the output signal generator 202 ICC and produces on output 48-bit data.

The encoder 206 (or channel encoder and puncture part) encodes the output signal generator 204 of the target bit. The encoder 206 may be an encoder with convolution or turbocode having the encoding rate of the R=1/2 and a limited length K= 9. Then, the encoder 206 outputs 96 characters. Interleaver 208 performs interleaving of the symbols received from the encoder 206. In this case, the interleaver 208 may be a block paremaibiabal long codes which represent specific user codes assigned to the respective subscribers. The selector 212 bits thins long codes, in order to negotiate the transmission speed data length code rate of the data symbols, which are output from the interleaver 208, and generates a select signal for determining the provisions of the control bits. In this case, managing a bit can be a bit power control (BOOM). The operator 214 XOR performs an exclusive OR operation on the encoded symbols, which are output from the interleaver 208, and over the long codes, which are output from the selector 212 bits.

Converter 216 signal (or multiplexer and a part of the display point signal) further demultiplexes the output data of the operator 214 of the exclusive OR signal of the I-channel (first channel signal) and the signal of the Q-channel (second channel signal). In addition, the Converter 216 converts the signal level of the data symbol by replacing the "0" to "+1" and "1" to "-1". The controller 218 gain channel controls the gain of the first channel signal from the Converter output signal 216 in accordance with the control signal amplification. The controller 220 gain channel control the signal gain.

The controller 222 increase the control bits accepts a control bit, which must be entered in a dedicated control channel, and controls the gain of the control bits in accordance with the control signal amplification. In this case, the control bits are produced with a speed of 16 bits per frame. If the control bit is a control bit power control bit is generated as "+1" or "-1" to increase or decrease the capacity of the terminal. The input device 224 receives the output signals of the controller 218 gain channel and controller 222 gain control bits, outputs the signal of the first channel from the output of the controller 218 gain channel and enters managing bits from the output of the controller 222 of the gain control bits at intervals of N symbols in accordance with the selection of the selector 212 bits. The input device 226 receives the output signals of the controller 220 gain channel and controller 222 gain control bits, outputs the signal of the second channel from the output of the controller 220 gain channel and enters managing bits from the output of the controller 222 of the gain control bits at intervals of N symbols in accordance with the selection of the selector 212 bits. If N=12, input devices 224 and 226 performs input control bit signals in the first characters for input devices 224 and 226. Managing bits can be entered in a regular or random intervals. In one embodiment, the implementation of managing a bit is entered in a pseudo-random intervals using a lower bit long codes.

Generator 232 orthogonal codes generates orthogonal codes in accordance with W the orthogonal code and a length of Wlengthorthogonal code. In this case, the orthogonal code may be a Walsh code or quasiorthogonal code. The multiplier 228 generates orthogonal modulated first channel signal IW by multiplying the first channel signal output from the first input device 224 on orthogonal code. The multiplier 230 generates orthogonal modulated second channel signal QW by multiplying the second channel signal output from the second input device 226 on orthogonal code.

Generator 252 ICC (Fig.2B) produces 12-bit ICC and adds it to the 172-bit control data in the received message frame is 20 MS, thus, carrying out the conclusion 184-bit data. Generator 254 target bit produces terminal 8 bits to indicate the end of the control message frame is 20 MS, and adds them to the output signal generator is here) encodes the control message frame is 20 MS, which comes from the generator terminal 254 bits. Encoder 256 may be a convolutional encoder or turbocode having the encoding rate of the R=1/2 and a limited length K=9. Thus, the encoder 256 outputs 384 characters. Interleaver 258 performs interleaving of the data symbols output from the encoder 256. In this case, the interleaver 258 may be a block interleaver and outputs 384 symbols per frame of 20 MS with a data rate of 19.2 kbit/s

Generator 260 long codes produces long codes that are specific user codes designated for the appropriate users. The selector 262 bits thins long code for matching the transmission speed data length code at a transmission rate of data symbols, which are output from the interleaver 258, and generates a select signal to determine the position of the insertion control bits. In this case, managing a bit can be a bit power control (BOOM). The operator 264 XOR performs an exclusive OR operation on the coded symbols output from the interleaver 258 and over long codes from the output of the selector 262 bits.

The Converter 266 signals (or multiplexer and a part of the display point signal) further demultiplexes the data of the actual signal). In addition, the Converter 266 signals converts the level of the data symbols by replacing the "0" to "+1" and "1" to "-1". Controller 268 gain channel controls the gain of the first channel signal from the Converter output signal 266 in accordance with the control signal amplification. The controller 270 gain channel controls the gain of the signal of the second channel from the output of inverter 266 signal in accordance with the control signal amplification.

The controller 272 increase the control bits of the Manager receives the bit that is put into the allocated control channel, and controls the gain of the control bits in accordance with the control signal amplification. In this case, the control bits are produced using 16 bits per frame. If the control bit is a bit power control, it is produced as "+1" or "-1" to increase or decrease the capacity of the terminal. The input device 274 receives the output signals of the controller 268 gain channel and controller 272 increase the control bits, outputs the channel signal from the output of the controller 268 gain channel and enters managing bits from the output of the controller 272 increase the control bits at intervals of N symbols in accordance with the select signal output select the of the control bits, displays the signal of the second channel from the output of the controller 270 gain channel and enters managing bits from the output of the controller 272 gain control bits at intervals of N symbols in accordance with a select signal from the output of the selector 262 bits. In this case, when N is equal to 12, the input device 274, 276 impose managing bits in the signal of the corresponding channel every 12 bits. The selector 262 bits generates a select signal for selecting the positions of the input symbols for input devices 224 and 226, and managing a bit may be introduced through the same or pseudo-random intervals. In a possible embodiment, the control bits are inserted at random intervals using a lower value bits of the long code.

Generator 282 orthogonal codes generates orthogonal codes in accordance with W , the orthogonal code and the length of Wlengthorthogonal code. In this case, the orthogonal code may be a Walsh code or quasiorthogonal code. The multiplier 278 produces orthogonal modulated first channel signal IW by multiplying the signal of the first channel with the output of the first input device 274 on orthogonal code output from the generator 282 orthogonal codes. Multiply the output signal of the second input device 276 on orthogonal code output from the generator 282 orthogonal codes.

Below is a description of the operation of the generator 103 direct dedicated control channel with reference to Fig.2A and 2B. In the communication system MDRC IS-95 frame size is fixed and is 20 MS. However, a control message for allocating and deallocating channels during communication must have a fast response time. Therefore, when the second control message with a fixed frame duration of 20 MS in the allocation and freeing of channels, the communication system may experience a significant delay due to the large response time. To solve this problem, in the present embodiment, the control message with the 5 MS frame is used for immediate control message for allocating and deallocating channels, and a control message with a frame of 20 MS is used for normal control messages and to control the switching of the communication channels, Desk location and call control. In another embodiment of the present invention, the communication system may use a control message from the first frame of 5 MS or message with the second frame is 20 MS in accordance with the length of the processed messages.

Control message having a length of the first frame is 5 MS, which contains the starting time of work allocated to the channel. Generators 202 and 252 ICC add bits of the ICC in the input signal, so the receiver can determine the quality of the frame. If the input signal has a frame length of 5 MS, the generator 202 ICC adds 16-bit ICC in the input signal. If the input signal has a frame length of 20 MS, the generator 252 ICC adds 12-bit ICC in the input signal.

Generators 204 and 254 target bits, the receiving control messages, which are added to the bits of the ICC, to produce the target bits and adds the generated target bits in the next bit position ICC. In this case, the generators 204 and 254 of the target bits to produce 8 of the target bit, despite the length of the frame. Target bits indicating the end of frame is received the control message, is added to initiate the encoders 206 and 256, which is connected to the terminal stages of the generators 204 and 254 of the target bit.

It is assumed that the encoders 206 and 256 are convolutional encoders that have a limited length K=9 and rate coding R=1/2. Premarital 208 and 258 perform interleaving of the data symbols, which are output from the encoders 206 and 256 by replacing placement of characters in the element frame, in order to improve the resistance to the package error. Generators 210 and 260 long codes of vyrabatyvat the Yelsk information. The selectors 212 and 262 bits select the output bits of the long code from the outputs of the generators 210 and 260 long codes in order to negotiate the transmission speed bit long codes with transmission rate of output bits of premaritally 208 and 258. Operators 214 and 264 exclusive OR perform an exclusive OR operation on alternating signals from the outputs of premaritally 208 and 258 and above the selected long code from the outputs of the selectors 212 and 262 bits.

Converters 216 and 266 of the divided signals output signals operators 214 and 264 of the exclusive OR signal of channel I and channel signal Q and transform the level of transmitted signals. That is, the transmitted signal "1" is replaced with "-1" and the signal "0" is replaced by "+1". Controllers 218, 220, 268 and 270 amplification channels, which represent adders gain data channels, add gain value in accordance with the control signal power to the input signals. The controllers 222 and 272 gain control bits control the gain values of the control signals of the power control bits received from the top-level object. Each of the input devices 224, 226, 274, 276 adds one character to control power to the 12 bits of data of the respective channels. In this case, bits control the second communication channel bits of the power control can be added to a dedicated control channel or the main channel. Detailed description for this case is shown below.

Multipliers 228, 230, 278 and 280 multiply the received signals of the channels in orthogonal codes from the outputs of the generators 232 and 282 orthogonal codes. Orthogonal codes, which are used in the forward dedicated control channel, are chosen from among the orthogonal codes that were not allocated a dedicated channel (i.e., dedicated control channel, the main channel and the additional channel and a shared channel (i.e. channel pilot signal, synchronal and paging channel). In this case, Walsh codes or quasiorthogonal codes can be used for orthogonal codes.

Generator 311 ICC outputs 40-bit data by adding 16-bit ICC to 24-bit control data. Generator 313 target bit produces terminal 8 bits to indicate the end of the control message frame is 5 MS, and adds the target bits to 40 the range control message from the generator output terminal 313 bits. Convolutional encoder or turbocode can be used for encoder 315. It is assumed that the encoder 315 is a convolutional encoder with bit rate R=1/4 and a limited length K=9. In this case, the encoder 315 outputs the 192 character. Interleaver 317 performs interleaving of the output signal of the encoder 315. Block interleaving can be used for the interleaver 317. Repeater 319 characters repeats the data symbols output from the interleaver 317. In this case, the repeater 317 characters displays the data symbols with the speed 1,2288 MS/s (elementary signals per second) for the number of repetition symbols, N= 8, when 3,6864 MS/s for N=24, 7,3728 MS/s for N=48, when 11,0592 MS/s for N=72 and 14,7456 MS/s for N=96. The Converter 321 converts the signals level symbols from the output of the repeater 319 characters, by changing "0" to "+1" and "1" to "-1".

Generator 351 ICC outputs 184 bits of data by adding a 12-bit ICC to 172-bit control data. Generator 353 target bit produces terminal 8 bits to indicate the end of the second control message frame is 20 MS, and adds the target bits to the 184-bit d is awsomee message of the second frame with the generator output terminal 353 bits. Convolutional encoder or turbocode can be used for encoder 355. It is assumed that the encoder 355 is a convolutional encoder with bit rate R=1/4 and a limited length K=9. In this case, the encoder 355 768 displays characters. Interleaver 357 performs interleaving of the output signal of the encoder 355. For the interleaver 357 you can use block interleaving. Repeater 359 characters repeats the data symbols output from the interleaver 357. In this case, the repeater 357 outputs the data symbols at the symbol rate 1,2288 MS/s for N=8 characters repeat when 3,6864 MS/s for N= 24, 7,3728 MS/s for N=48, when 11,0592 MS/s for N=72 and 14,7456 MS/s for N=96. Converter 361 converts the signal level of the symbols output from the repeater 359 characters by replacing "0" with "+1" and "1" to "-1".

Forward and reverse dedicated control channels, according to the present invention, allow for the transfer of control message in transmission mode with interrupts using the control signal of the controller 101, in case there is no need to transmit a control message.

Generator 153 reverse dedicated control channel, which, as shown, has the same structure as in Fig.3A and 3B, works the same, except that generalrevenue embodiment, the present invention provides the transmission control bit reverse power using the pilot signal, generator 153 reverse dedicated control channel does not necessarily require the presence of certain patterns to add separately-bit power control. Accordingly, the generator 313 and 353 target bits, the encoder 315 and 355 and premarital 357 317 and work in the same way as described above. In addition, repeaters and 359 319 characters recurring characters N times, taking into account relevant data speeds, and converters 321 and 361 signals, convert the level of repeated characters from the outputs of the repeaters 319 and 359 characters.

That is, the generators 103 and 153 dedicated control channels transmit a control message in transmission mode with interrupts (PSC), which is described in detail in the patent application Korea 4498/1998, the applicant of the present invention.

Fig.4A-4C depict the structure of the generator 111 direct main channel in accordance with the data rates and frame lengths.

In Fig.4A generators 401, 411, 421 and 431 ICC add 12, 8, 6 and 6 data bits ICC to the data input, respectively. More specifically, the generator 401 ICC adds 12-bit ICC to 172-byte data from the first transmission speed to output 184 bits, the generator 411 ICC adds 8 bits ICC to the 80-bit data from the second transmission speed to output 88 bits, the generator 421 ICC adds 6 bits ICC to 40-bit data from the third speed of the transmission output 46 bits and generator 431 ICC adds 6 bits ICC to 16-bit data with the fourth transmission rate to output 22 bits.

Generators 402, 412, 422, 432 target bit add 8 target bits to the output signal generator 401, 411, 421 and 431 ICC, respectively. Thus, the first generator 402 target bit outputs 192 bits, the second generator 412 of the target bit outputs 96 bits, the third generator 422 terminal bit outputs 54 bits, and the fourth generator 432 target bit 30-bit displays.

Coders 403, 413, 423 and 43433 you can use convolutional encoder with K= 9, R= 1/2. In this case, the first encoder 403 encodes a 192-bit data from the output of the first generator terminal 402 bits and outputs 384 character with full speed transmission. The second encoder 413 encodes a 96-bit data from the output of the second generator 412 of the target bit, and outputs 192 symboltransmission speed. The third encoder 423 encodes a 54-bit data from the output of the third generator 422 termination bits and outputs 108 characters with a speed of 1/4. The fourth encoder 433 encodes the 30-bit data from the output of the fourth generator terminal 432 bits and outputs 60 characters with a speed of 1/8.

Repeaters 414, 424 and 434 of the recurring characters from the outputs of the encoders 413, 423 and 433 twice, four times and eight times, respectively, in order to agree the appropriate number of characters number of characters with full speed transmission. Blocks removal 425 and 435 characters delete characters that repeat and exceed the number of symbol full speed transmission repeaters 424 and 434, respectively. In other words, the repeater 414, 424 and 434 repeat the input characters matching the number of characters number of characters at full speed transmission (i.e., 384 characters). When the number of characters that are repeated in the repeaters 424 and 434, exceed the number singolare characters to numbers of characters at full speed. Since the number of symbols from the output of the second encoder 413 is 192, which is equal to the number of characters from the output of the first encoder 403, the second repeater 414 repeats the received symbols twice to output 384 characters. Similarly, as the number of symbols from the output of the third encoder 423 is 108, which is approximately equal to 1/4 the number of characters from the output of the encoder 403, the third repeater repeats 424 accept characters four times for output 434 of characters that exceeds the number of 384 characters with full speed. For approval 432 characters with 384 symbols, the third block 425 delete characters removes every ninth symbol from the display 432 characters. In addition, since the number of symbols from the output of the fourth encoder 434, 60, which is approximately equal to 1/8 of the number of symbols output from the first encoder 403, the fourth repeater 434 repeats the received symbols 8 times for output of 480 characters that exceeds the number of 384 characters with full speed. For approval 480 characters with 384 symbols, the fourth block 435 delete characters deletes every fifth symbol of 480 characters.

In possible variants of implementation of the present invention uses a block interleaving or arbitrary interleaving. Premarital 406, 416, 426 and 436 deduce 384 symbols per frame with data rate of 19.2 kbit/s

According Fig.4C, the generator 452 long codes produces long codes, which are codes for the identification of subscribers. The selector 454 bit thins long codes to negotiate transmission speed data length code rate of the data symbols, which are output from the corresponding one of premaritally 406, 416, 426, 436 and 446, and generates a select signal for determining the position of the input control bits, which can be a bit power control. The operator 456 XOR performs a logical exclusive OR operation on long codes from the output of the selector 454 bits and the interleaved symbols from the outputs of premaritally 406, 416, 426, 436 and 446.

The controller 464 gain control bits accepts a control bit, which will be introduced in a dedicated control channel, and controls the gain of the control bits in accordance with the control signal amplification. In this case, the control bits are produced in order to enter up to 16 bits per frame. If the control bit is a bit power control, managing bit is produced in the form of "+1" or "-1" to increase or decrease the capacity of the terminal. The input device 468 receives the output signals of the controller 460 gain of channel I and controller 464 gain control bits and enters managing bits from the output of the controller 464 gain control bits produced at intervals of N symbols by selecting the selector 454 bits in the channel signal I output from the controller 460 gain channel I. the input Device 470 receives the output signals of the controller 462 gain of the Q channel and controller 464 gain control bits and enters managing bits from the output of the controller 464 gain control bits, produced at intervals of N symbols by selecting the selector 454 bitwoded input control bits in the signals of channels I and Q in the interval of 12 characters, accordingly, the selector 454 bit generates a signal to select positions for character input in the input device 468 and 470. The input position control bits can be periodic or may vary in a pseudo-random. In the present embodiment, the present invention managing a bit introduces a pseudo-random with the use of certain low-order bit of the long code.

Generator 727 orthogonal codes generates an orthogonal code according to the number of W orthogonal code and a length of Wlengthorthogonal code. For orthogonal code you can use Walsh codes or quasiorthogonal code. In the case when the orthogonal code is a Walsh code generator 113 additional channel can be used 128-, 64-, 32-, 16-, 8- and 4-bit Walsh code in accordance with the frame length of the input data.

Generator 719 long codes produces identification codes assigned to respective users, and Decimator 721 negotiate speed data transmission frame from the output of the interleaver 717-rate data length code. The operator 723 XOR performs a logical exclusive OR operation with the output signal of the interleaver 717 and the output signal of Decimator 721 to encrypt the signal channel.

Then the Converter 725 signals divides the output signal of the operator 723 exclusive OR signals of channels Q and I, and converts the signal "0" to "+1" and "1" to "-1". Multipliers 729 and 731 produce a multiplication of the transformed signals of channels I and Q orthogonal codes, respectively, for orthogonal modulation, and controllers 733 and 735 gain channel compensate for the gain channels.

In Fig.8 shows a diagram of the generator 161 reverse channel. According Fig. 8, the generator 802 ICC produces bits of the ICC in accordance with the input data frame and adds them together with the input data frame. The generator terminal 804 bits, which receives the output signal generator 802 ICC, produces terminal 8 bits to indicate the end of input frame data and adds them together with the frame data. The Encoder 806 Abcoder. It is assumed that the encoder 806 is a convolutional encoder with K=9, R= 1/4. Repeater 808 character repeats the symbols from the output of the encoder 806 to generate encoded data at a certain speed. Removal unit 810 performs the removal of some of the recurring characters, and interleaver 812, which is the block interleaver performs interleaving of the output signal removal unit 810. Repeater 814 repeats N times the symbol on which the operation was performed alternation in the interleaver 812, and the inverter 816 signals converts the level of repeated symbols at the output of the repeater 814 by changing the level "1" to "-1" and level "0" to "+1".

Generator 161 reverse channel, the scheme of which is shown in Fig.8, has the same pattern as the generator 113 direct additional channel except that the generator 161 reverse channel includes a removal unit 810 to remove some of the encoded data. Removal unit 810 "pierces" extra bits to adjust the data bit output signal.

In Fig.9A-9C shows the schematic construction of the generator 105 forward link pilot signal generator 107 direct synchronal and generator 109 direct paging channel, couvet signal, the inverter 914 signals converts the level of the pilot signal. The multiplier 915 produces a multiplication of the pilot signal from the output of the inverter 914 signals on orthogonal code WO for orthogonal modulation of the pilot signal. It is assumed that the data bits of the pilot signal are all "0" and the orthogonal code is a Walsh code. Then the generator 105 channel pilot signal receives the data of the pilot signal (all "0") and extends along the spectrum data of the pilot signal by selecting a particular code WO Walsh Walsh code.

In Fig.9B is a diagram generator 107 synchronal. Encoder 921, which may be a convolutional encoder or turbocode, encodes the data input synchronal. It is assumed that the encoder 921 is a convolutional encoder with K= 9, R= 1/2. Repeater 922 repeats the symbols from the output of the encoder 921 N times (where N= 1), and the interleaver 923, which is a block interleaver that performs interleaving of the symbols that are output from the repeater 922 to prevent mistakes package. Converter 924 signals converts the signal level of synchronal, which is output from the interleaver 923. The multiplier 925 produces a multiplication of the signal synchronal inverter output signal 924, orthogonal code W32 La maintain synchronization between the base station and the terminal encodes synchrodyne through a convolutional encoder with K=9, R=1/2, produces repetition encoded data once through repeater 922 and then performs interleaving the encoded data via the interleaver 923. Then the generator 107 direct synchronal orthogonal modulating synchrodyne by multiplying the alternating synchrogenix on a dedicated orthogonal code W32 of orthogonal codes using multiplier 925.

In Fig.9C shows a diagram of the generator 109 direct paging channel. Encoder 931, which may be a convolutional encoder or turbocode, encodes the input paging data. It is assumed that the encoder 931 is a convolutional encoder with K=9, R=1/2. Repeater 932 repeats the symbols that are output from the encoder 931 N times (where N=0), and the interleaver 933, which is a block interleaver that performs interleaving symbols from the output of the repeater 932 to prevent the failure of a batch. Generator 936 long codes produces long codes, which are codes for the identification of subscribers. Decimator 937 thins long code for speed negotiation data long code-rate data symbols output from the interleaver 933. The operator 938 XOR performs a logical operation on the IP Decimator 937. Converter 934 signals converts the level of the paging data output operator 938 exclusive OR, and the multiplier 935 orthogonal modulating paging data by multiplying the paging signal is encoded in the operator 938 exclusive OR orthogonal code Wp output paging channel.

Thus, the generator 109 direct paging communication channel is similar to the generator 107 synchronal except that the generator 109 paging channel performs a logical exclusive OR operation on the output signal of the interleaver 933 and long code and expands the spectrum paging data by multiplying the paging data to code Wp Walsh, dedicated paging channel.

In Fig. 10A shows the construction scheme generator 155 reverse channel pilot signal, in the present embodiment adds a bit power control for the reverse pilot channel for transmitting bits of the power control. Therefore, as shown in the drawing, the generator 155 channel pilot signal is performed so that the bit power control is added to the pilot channel signal. In Fig. 10B shows the format of the pilot signal and the control signal power received from kinlochbervie speed data transmission. More specifically, the generator 155 pilot channel transmits one bit power control (MIND) to the group power control (GUM) and 16-bit power control on the frame. Therefore, the repeater 1002 symbols has N=1 for 1,2288 MS/s, N=3 for 3,6864 MS/s, N=6 for 7,3728 MS/s, N= 9 for 11,0592 MS/s and N=12 for 14,7456 MS/s Multiplexer 1004 that receives the reverse pilot signal and bits of the power control output of the repeater 1002 characters, eliminate the pilot signal, and outputs the bit power control in accordance with the signal Sel_L choice.

Fig. 10B depicts the characteristics of the pilot signal from the output of the multiplexer 1004 bits and power control. When the transfer of bits of power control through the reverse channel pilot signal multiplexer 1004 introduces a bit of power control in a certain position of the group power control, consisting of four 384N PS elementary signals (Fig.10V).

Fig. 11A-11C depict a scheme for constructing a generator 157 reverse access channel, where Fig.11A shows the generator 157 access channel, which has a data rate of 9600 bit/s, and Fig.11B shows the generator 157 access channel, which has a data rate of 4800 bits/s

According Fig. 11A and 11B, generators 1111 and 1121 ICC add the appropriate bits C is DNAM data for output 184-bit data, and generator 1121 ICC adds 8-bit data ICC to 80-bit input data to output 88-bit data.

Generators 1112 and 1122 target bit add 8 target bits to the output signals of the generators 1111 and 1121 ICC, respectively. As a result, the generator terminal 1112 bit outputs 192-bit data, and the generator 1122 target bit outputs 96-bit data.

Coders 1113 and 1123 encode the output signals of the generators 1112 and 1122 target bits, respectively. Coders 1113 and 1123 may be convolutional encoders with K=9, R=1/4. In this case, the encoder 1113 encodes a 192-bit data output from the generator 1112 target bits for output 768-bit data, and the encoder 1123 encodes a 96-bit data output from the generator 1122 target bits for output 384-bit data.

Premarital 1114 and 1124, which may be a block peremejaemye or arbitrary peremejaemye perform interleaving saldirovannyj data from outputs of the encoders 1113 and 1123, respectively. It is assumed that for premaritally 1114 and 1124 are block premarital.

Repeater 1125 repeats (transmits) the symbols output from the interleaver 1124 twice, thus ensuring the withdrawal of 768 characters. Repeater 1125 provides the coordination mode with a baud rate of char is Moly with outputs of the interleaver 1114 and repeater 1125 N times, respectively. Thus, repeaters 1116 and 1126 characters together deduce N*768 symbols in a frame with a data rate of 19.2 kbit/s Converters 1117 and 1127 signals converts the signal level of the characters from the outputs of the repeaters 1116 and 1126 characters, respectively.

As described above, if the data transmission speed of 4800 bps, generator 157 access channel transmits peremerzanie data twice consecutively before serving perenesennyj data in the repeater 1126 characters. Thus, the generator 157 regulates channel access data access channel with a data rate of 4800 bit/s per channel data access with data transmission speed 9600 bits/s

In Fig.11C shows a diagram of the device of the extension of the spectrum to broaden the spectrum of the signal of the access channel from the output of the generator 157 access channel using the pilot signal from the output of the generator 155 channel pilot signal. In Fig.11C shows an example of an integrated expansion unit based spectrum FMC.

According Fig. 11S multiplier 1150 generates orthogonal modulated signal of the pilot channel by multiplying the signal of the pilot channel orthogonal code, and the multiplier 1151 produces orthogonal modulated signal of channel access by the mind is also or quasiorthogonal code. The controller 1153 gain controls the gain of the orthogonal modulated signal of the access channel from the output of the multiplier 1151.

The multiplier 1155 produces a multiplication sequence spread spectrum PNI channel I at long code that represents the user identification code. The multiplier 1157 produces a multiplication sequence spread spectrum channel PNQ Q long code. The multiplier 1159 produces a multiplication of the orthogonal modulated signal pilot channel sequence spread spectrum PNI channel I output multiplier 1155, and the multiplier 1161 produces a multiplication of the orthogonal modulated signal channel access sequence spread spectrum PNI channel I output multiplier 1155. The multiplier 1163 produces a multiplication of the orthogonal modulated signal channel access sequence spread spectrum channel PNQ Q from the output of the multiplier 1157, and the multiplier 1165 produces a multiplication of the orthogonal modulated pilot signal sequence spread spectrum channel I output multiplier 1157. Subtractive device 1167 produces advanced signal XI of channel I by subtracting the output signal of the multiplier 1163 from the output signal of the multiplier vyhodnym signal 1165. Therefore, the expansion device having the structure described above, produces a value of a difference between the output signals of the multipliers 1159 and 1163, as advanced signal XI of channel I, and produces a signal summing output signals of the multipliers 1161 and 1165, as advanced signal XQ channel Q.

Filter 1171 frequency band signal filtered enhanced signal XI channel I from the output of subtractive device 1167, and the filter 1173 frequency band signal filtered enhanced signal XQ of Q channel output of the adder 1169. The controller 1175 gain controls the gain of the extended channel signal I from the output of the filter 1171 bandwidth video signal, and the controller 1177 gain controls the gain of the extended channel signal Q from the output of the filter 1173 bandwidth video signal. Mixer 1179 generates the RF signal of channel I by mixing the output signal of the controller 1175 gain with carrier cos(2fct) of channel I, and the mixer 1181 generates the RF signal of the Q channel by mixing the output signal of the controller 1177 gain with carrier sin(2ct) channel Q. the Adder 1183 generates the RF signal transmission by adding the RF signals of channels I and Q outputs of smeasy channel and the pilot signal, receives the pilot signal component of the channel I, and the signal of channel access as a component of the Q channel, and extends the signal of channel I and Q using sequence spread spectrum PNI and PNQ channels I and Q. the output Signal from the access channel is modulated using orthogonal code multiplier 1151, and the relative gain of the signal channel access in relation to the signal of the pilot channel is compensated in the controller 1153 gain. The output signals of the multiplier controller 1150 and 1153 gain multiplied by the sequence spread spectrum PNI and PNQ through multipliers 1155-1165, thus fulfilling the extension. Then the gain values of the enhanced signals are compensated through the controller 1175 and 1177 gain.

In Fig. 12 shows a diagram that explains the orthogonal modulation and expansion operation on the spectrum of the corresponding generators of the channels that are part of the reverse channel.

In the known system mdcr transmitter reverse communication channel comprises a pilot channel signal, a main channel, an additional channel and a control channel. The generator control channel accepts 10-bit control message and adds the signal power control is aetsa too small in size to transfer a large number of control signals power what causes slow performance of the system. In addition, for normal voice communication, which enables the transfer of only the speech signal through the main channel, known in the communication system mdcr uses the pilot channel signal, an additional channel and a control channel. The control channel must support the control signal power. This method of transmitting information power control uses at least three channels for normal voice communication, thus decreasing the ratio of maximum value to the average value of the transmitting amplifier. In order to perform communication using packet data, the above-mentioned method, it is necessary to allocate the pilot channel and the additional channel, then select the primary channel control channel and then select the control channel signal transmission power control. Accordingly, for communicating packet data in a known communication system mdcr you must use a total of four channels.

It should be noted that in the embodiment of the present invention uses a dedicated control channel, which is different from the control channel, which is known to the system is operating signals, thus, allowing you to solve the problem of overload in the well-known system for mobile communications mdcr. In addition, as this
an implementation option allows you to transfer the bits of the power control by entering them in the pilot channel signal, it allows you to transmit the voice signal using only channel pilot signal and the main channel for normal voice communication, without allocation of a single control channel for power control. For communication using packet data, this alternative implementation can transmit packet data using the pilot channel signal, and an additional channel and with the appointment of a dedicated control channel for the control channel. As the signal power transmitted by entering it into the pilot channel signal, no need for the appointment of an additional channel for signal power control. In this way, the invention allows to save one channel in the reverse link channel in comparison with the known method. As a result, in the invention obtained lower the ratio of maximum value to the average value, so the terminal can have a wider coverage area even when using that is by multiplying the pilot signal and the control signal power of the pilot channel signal by the orthogonal code. The multiplier 1202 generates orthogonal modulated signal dedicated control channel by multiplying the signal the dedicated control channel from the output of the generator 153 a dedicated control channel on the selected orthogonal code. The multiplier 1204 generates orthogonal modulated signal channel by multiplying the signal channel from the output of the generator 161 additional channel on a dedicated orthogonal code. The multiplier 1206 generates orthogonal modulated signal of the main channel by multiplying the signal of the main output channel generator 159 main channel on a dedicated orthogonal code.

The controller 1208 gain controls the gain of the orthogonal modulated signal a dedicated control channel from the output of the multiplier 1202. The controller 1210 gain controls the gain of the orthogonal modulated signal channel from the output of the multiplier 1204. The controller 1212 gain controls the gain of the orthogonal modulated signal of the main channel from the output of the multiplier 1206. Controllers 1208-1212 amplification are used for compensation of the pilot signal and the relative gain with respect to the input signals of the channels is of ihoda multiplier 1200 with the output signal of the controller 1208 gain. Generator 155 pilot channel may develop a pilot signal with bits of the power control. The adder 1216 adds the output signal of the controller 1210 gain with the output signal of the controller 1212 gain. That is, the adder 1214 adds the pilot signal with the signal the dedicated control channel and the adder 1216 adds an additional signal channel signal of the main channel.

The multiplier 1218 performs multiplication sequence spread spectrum PNI channel I at long code, and the multiplier 1220 performs the multiplication sequence spread spectrum channel PNQ Q long code. The multiplier 1222 performs the multiplication of the output signal of the adder 1214 on the sequence spread spectrum PNI channel I output multiplier 1218, and the multiplier 1224 performs multiplication of the output signal of adder 1216 on the sequence spread spectrum PNI channel I output multiplier 1218. The multiplier 1226 produces a multiplication of the output signal of adder 1216 on the sequence spread spectrum channel PNQ Q from the output of the multiplier 1220, and the multiplier 1228 performs multiplication of the output signal of the adder 1214 on the sequence spread spectrum channel PNQ Q from the output of the multiplier 1220. Subtractive device 1230 waraba and the adder 1232 produces advanced signal XQ of Q channel by adding the output signal of the multiplier 1224 with the output signal of the multiplier 1228. That is, the expansion unit generates the value of the difference between the two signals from the outputs of the multipliers 1222 and 1226 in the form of enhanced signal XI of channel I and the sum value of the two signals from the outputs of the multipliers 1224 and 1228 in the form of enhanced signal XQ channel Q.

Filter 1234 bandwidth video filters in the main frequency band extended signal XI channel I from the output of subtractive device 1230, and the filter 1236 bandwidth video filters in the main frequency band extended signal XQ of Q channel output of the adder 1232. The controller 1238 gain controls the gain of the extended channel signal I from the output of the filter 1234 bandwidth video signal, and the controller 1240 gain controls the gain of the extended channel signal Q from the output of the filter 1236 bandwidth video signal. Mixer 1242 generates the RF signal of channel I by mixing the output signal of the controller 1238 gain with carrier cos(2fct) of channel I, and the mixer 1244 generates the RF signal of the Q channel by mixing the output signal of the controller 1240 gain with carrier sin(2fct) channel Q. the Adder 1248 generates the RF signal transmission by adding the RF signals of channels I and Q outputs see what the operators return channel with reference to Fig.12. Generator 153 dedicated control channel generator 161 additional channel generator 159 main channel broaden the spectrum of their channel signals using respective orthogonal codes, respectively, and compensates for the relative gains of the respective channels based on the pilot signal. Reverse channels divided by the modulation of the respective channels by using different orthogonal codes. In this case, the orthogonal codes intended for separation of the respective channels are allocated to users who are within the coverage area of the same base station. Therefore, the orthogonal modulated signal to the selected control channel is orthogonal modulated pilot signal and the orthogonal modulated signal channel is orthogonal modulated signal of the main channel. The expansion unit 167 then receives two signals sum in the form of signals of channels I and Q, respectively, and extends along the spectrum signals of channels I and Q. the Controller 1238 and 1240 gain offset gain extended signals.

Unlike the forward link pilot signal on the reverse channel pilot signal is. Thus, from the viewpoint of the base station, since the corresponding target device produce different pilot signals, reverse link pilot signal is a dedicated channel pilot signal. The transmitter reverse pilot channel signal has two different ways to extend the spectrum of the transmission signal. The first way is to identify users using PS-code. The method allows to extend the spectrum signals of the respective channels using the preset codes Walsh, intended to separate the respective channels. In this case, different Walsh codes are allocated to the respective channels and the same Walsh codes are allocated to the same channel for all users. The second way is to identify users using a Walsh code. This method allows to extend the spectrum signals of the respective channels by using four Walsh codes allocated in a different way for each user, and uses SS-code identification of the base station.

Fig. 13 depicts a diagram of an orthogonal modulation and modulation spread spectrum signals of the channels of the generators of the backward channel. In Fig.13 orthogonal modulator 1311) modulated pilot signal. The orthogonal modulator 1313 generates orthogonal modulated signal dedicated control channel by multiplying the signal the dedicated control channel, which is derived from the generator 153 dedicated control channel, a dedicated orthogonal code. The orthogonal modulator 1315 produces orthogonal modulated signal of the main channel by multiplying the signal of the main channel, which is derived from the generator 159 main channel, on the selected orthogonal code.

The controller 1317 gain controls the gain of the orthogonal modulated signal pilot channel, which contains bits of power control, the output of the orthogonal modulator 1311. The controller 1319 gain controls the gain of the orthogonal modulated signal a dedicated control channel from the output of the orthogonal modulator 1313. The controller 1321 gain controls the gain of the orthogonal modulated signal of the main channel from the output of the orthogonal modulator 1315.

The adder 1323 performs addition of the output signal of the controller 1317 gain with the input signal from the controller 1319 gain. The output signal generator 155 channel pilot signal can b is Irene PNI spectrum of channel I for a particular user long code and the multiplier 1329 produces a multiplication sequence spread spectrum channel PNQ Q on specific user long code. The expansion unit 1325 receives the output signal of the adder 1323 in the form of a channel signal I and the output signal of the controller 1321 gain in the form of a channel signal Q and expands on the spectrum of the received signals of channels I and Q using sequence spread spectrum PNI and PNQ channels I and Q outputs of multipliers 1327 and 1329. The expansion unit 1325 can be integrated expansion unit substation, which consists of multipliers 1222-1228 and adders 1230 and 1232 (Fig.12).

The demultiplexer 1331 further demultiplexes the signal channel from the output of the inverter 816 signal generator 161 additional channel by dividing the signal channel on characters with an odd number and characters with an even number. Generator 1333 orthogonal codes produces orthogonal code Wi for orthogonal modulation symbols of an additional channel with an odd number. The multiplier 1335 produces multiplication of characters with odd numbers of outputs of the demultiplexer 1331 on orthogonal code Wi and outputs the orthogonal modulated symbols with odd numbers. Similarly, the generator 1337 orthogonal codes produces orthogonal code Wj for orthogonal modulation symbols of an additional channel with an even orthogonal code Wj and outputs the orthogonal modulated symbols with even numbers. Interleaver 1341 produces a signal channel, which is orthogonal modulated using a singleton robust code using alternation orthogonal modulated symbols additional channels from the outputs of the multipliers 1335 and 1339.

Although you can refer to the way in which you use a singleton sustainable code using two generators 1333 and 1337 orthogonal codes, the demultiplexer 1331 can modulate the signal channel using M-element stable code, using the demux input symbols of an additional channel on M symbols, orthogonal modulation M-symbols using the corresponding orthogonal codes from the outputs of the generators of M orthogonal codes, and then performs interleaving orthogonal modulated symbols through the interleaver 1341.

The controller 1343 gain controls the gain of the output signal of the interleaver 1341. Decimator 1345 thins code PNI for a particular cell to distinguish between the base station and the repeater 1347 characters repeats thinned PNI code twice. Decimator 1349 thins code PNQ for a particular cell to distinguish between the base station and the repeater 1351 characters repeats thinned code PNQ is a and repeat the input PS-codes M times for M-shell stable code. The multiplier 1353 produces advanced signal channel to channel I by multiplying the output signal of the controller 1343 gain code PNI from the output of the repeater 1347 characters. The multiplier 1355 generates advanced signal channel for channel Q by multiplying the output signal of the controller 1343 gain code PNQ from the output of the repeater 1351 characters.

The adder 1357 produces an enhanced signal of channel I by adding the extended channel signal of the first expansion unit 1325 with advanced signal multiplier 1353, and the adder 1359 produces advanced channel signal Q with the addition of the extended channel signal Q expansion unit 1325 with advanced signal multiplier 1355. Filter 1361 frequency band signal filtered by the extended channel signal I from the output of the adder 1357, and the filter 1363 frequency band signal filtered by the extended channel signal Q from the output of the adder 1359. The controller 1365 gain channel, which receives the output signal from the filter 1361 bandwidth video signal, controls the amplification of the extended channel signal I, and the controller 1367 gain channel, which receives the output signal from the filter 1363 band video is for output controller 1365 gain channel with carrier cos(2fct) of channel I, and the mixer 1371 generates the RF signal of the Q channel by mixing the output signal of the controller 1367 gain channel with carrier sin (2fct) channel Q. the Adder 1373 generates the RF signal transmission by adding the RF signals of channels I and Q outputs of mixers 1369 and 1371.

Below is a description of the operation of the adders 163 and 165 and the expansion unit 167 with reference to Fig.13. In Fig.12 generators of the respective channels modulate the signals of the channels using orthogonal code to distinguish between channels. However, in Fig.13 generator 153 dedicated control channel generator 155 channel pilot signal generator 159 main channel recognizes the channels using channel orthogonal codes (Fig.12) and a generator 161 additional channel produces discernment additional channel from the other channels using the singleton sustainable code instead of the Walsh code. Of course, the channels may vary using a Walsh code.

When you use a singleton sustainable code signal channel from the output of the generator 161 reverse channel, is divided into characters with odd numbers and symbols with even numbers with the aid of agonally codes. The modulated symbols with even and odd numbers are displayed alternately through the interleaver 1341. The additional channel signals from the output of the interleaver 1341 adjustable gain and then expanded using FP codes in the same way are assigned to users in the coverage area of the same base station. In addition, PS-codes to extend a singleton sustainable code were subjected to thinning out at intervals of one elementary signal. Generation singleton sustainable code described in the patent application Korea 39119/1997 the applicant of the present invention.

Transmitter return channel (Fig.13) modulates and expands on the spectrum of the signal channel otherwise than according to Fig.12. Further specifically, according to Fig.12, the signal obtained by adding the output signal generator 155 pilot channel signal with the output signal generator 153 dedicated control channel, and the signal obtained by adding the output signal generator 159 main channel with the output signal generator 161 additional channel, is entered in the device extension for further expansion. At the same time, according to Fig.13, the signal obtained by adding the output signal GE in the expansion unit 1325. Then, output signals of the expansion unit 1325 develop output signals, which were expanded using a singleton sustainable code generator 161 additional channel.

In Fig. 14A-14C shows the structure of a frame that is transmitted via the primary channel, the secondary channel and the access channel, respectively. As shown in the drawings, the frame of the main channel, the frame channel and the channel frame access include specific bits of information bits of the ICC, which provide the receiver the ability to measure the quality of a received frame, and the target bits for initiating coders.

In Fig. 15A and 15C shows the structure of frames that are transmitted through the dedicated control channel, and Fig.15A depicts the structure of the control message by the length of the first frame and Fig.15C depicts the structure of the control message with the length of the second frame. In a possible embodiment of the present invention, the length of the first frame is 5 MS and the length of the second frame is 20 MS.

As is shown in Fig. 15A and 15C, the frame control message has a different structure in accordance with its length. That is, as shown in Fig. 15A, the frame control message 5 MS and the target bits to initialize the encoder. In addition, (Fig.15V), the frame control message 20 MS consists of part (MO), which describes the type of the frame part (payload), which contains the contents of the data bits ICC to measure the quality of the frame and the target bit. In particular, the last frame includes padding to adjust the duration of the last frame to 20 MS, because the length of data that is transferred using a top-level object is a variable.

Walsh codes that are used in the transmitters and receivers of the reverse channel and direct channel of communication that can be replaced quasiorthogonal codes.

Below is a description of the functions of the respective channels in accordance with channel structure and types of services provided in each case with reference to the generators of the direct channel and the generators of the backward channel, is performed according to Fig.1-15V. After a call, you can make different combinations of channels of transmission/reception data (i.e., channel pilot signal allocated control channel, the main channel and secondary channel). Below with reference to Fig.16A-22V separately describes the direct channel and the reverse channel, which have different combinations, and then describes the types of services the purpose of the respective channels. In the description in more detail will be revealed the structure of the respective channels and their role. The invention can also be used for other services, as will be mentioned below. In Fig.16A-22V arrow pointing from the base station to a target device, indicates the direct channel, and an arrow directed from the terminal to the base station indicates the reverse channel.

The direct communication channel, you can perform seven ways as described below.

First, communication can be performed using the direct channel, which consists of a pilot channel signal and the main channel. In this case, all control messages are transmitted by adding to the main channel using the method of "shaded command-and-pack" or "pause-and-pack". The control signal power is transmitted through the main channel. In Fig.16B shows the algorithm to run normal voice communication in the direct communication channel, where direct communication channel consists of a pilot channel signal and the main channel.

After receiving a request message at a normal voice communication from the top-level base station, the controller 101 of the base station assigns the primary channel for communication, and then transmits the signal to the destination channel to the terminal by the final channel of the base station through a paging receiver channel and transmits the confirmation signal to the base station by including a generator 157 channel access. After receiving the confirmation signal from the terminal through the receiver of the access channel, the base station transmits voice data to the terminal via the primary channel by including a generator 111 of the main channel. In the direct channel of communication all control messages, including control signal power transmitted by adding them to the speech data of the main channel using the method of "shaded command-and-pack" or "pause-and-pack". For complete voice communication, the base station transmits a completion signal to the terminal through the generator 111 of the main channel. After receiving the completion signal, the terminal transmits the confirmation signal to the base station through the generator 159 main channel and then releases the connected main channel to the end of the voice communication.

Second, communication can be performed using a direct communication channel that consists of a pilot channel signal, a dedicated control channel and the main channel. In this case, the control signal power transmitted by adding it to the main channel, and other operating messages are transmitted through the dedicated control channel. Fig.17B illustrates an algorithm for performing voice communication services of high katestone and the main channel.

When receiving a request signal for voice communication of high quality at a direct channel from the top-level object base station controller base station 101 transmits a signal to the destination channel for the main channel and the dedicated control channel, designed for performing high-quality voice communication terminal through direct paging channel by the generator 109 paging channel. After receiving the call destination channel, the terminal transmits the confirmation signal to the base station via a reverse access channel by including a generator 157 channel access. After receiving the confirmation signal, which is transmitted from the terminal, the controller 101 of the base station transmits voice data to the terminal through a direct primary channel by including a generator 111 of the main channel. In this case, to transmit the control message when performing high-quality voice communication service through the primary channel controller 101 of the base station includes a generator 103 a dedicated control channel and transmits a control message via a direct dedicated control channel. At this point, the controller 151 of the terminal also provides an opportunity for the generator 153 obrateny control channel. Control message transmitted through the dedicated control channel during a voice communication, has a frame size of 20 MS. The base station can transmit bit power control through direct primary channel to control the transmit power of the terminal. In this case, the controller 101 of the base station enters the bits of the power control located in specific positions, and transmits them via direct primary channel by including a generator 111 of the main channel.

To complete the connection when performing voice communication services of high quality controller 101 of the base station transmits the request signal at the completion of the canal through a direct primary channel by including a generator 111 of the main channel. After receiving the request signal to shut down the channel, the controller 151 of the terminal transmits the confirmation signal to the base station through the reverse main channel by including a generator 159 main channel. Then, the controller 101 of the base station releases the main channel, thus ending voice communication. On the main channel can only be transferred signal power control and voice signal to the communication method had a higher communication quality in comparison with from Inanna command-and-pack" or "pause-and-package".

As described above, for high-quality voice communication base station and the terminal appoint a primary channel that will be used through a dedicated control channel. After the appointment of the main channel of the base station and the terminal serve the function of voice communication through the assigned primary channel and transmit a control message through a dedicated control channel if it has a control message for transmission when performing voice communication through the main channel. When voice communication is completed, the main channel is released, thus terminating the voice communication service. In addition, short and urgent control message, such as message about the assignment/release of the channel is transmitted in the frame of 5 MS, whereas normal operating message, such as message switching communication channels is transmitted in 20 MS frame.

Thirdly, communication can be performed using a direct communication channel, which includes a pilot channel signal in the main channel and the additional channel. In this case, the signal power control and another control message is transmitted through the main channel. In Fig.18B shows an algorithm for performing packet data communication services is a high channel.

After receiving the request signal to the communication packet data, the direct channel from the top-level base station controller base station 101 transmits the allocation requests for additional channel through direct primary channel by including a generator 111 of the main channel. After receiving the signal allocation request channel, the controller 151 of the terminal transmits the confirmation signal to the base station through the reverse main channel by including a generator 159 main channel. In this case, a control message, which is transmitted through the main channel, has a frame size of 5 MS. After receiving the confirmation signal, the controller 101 of the base station transmits packet data through a direct channel by the generator 113 additional channel. When it is necessary to transmit a control message in the communication process using batch data via a dedicated channel, the controller 101 of the base station transmits a control message frame 20 MS after the direct primary channel by including a generator 111 of the main channel. In addition, when it is necessary to transmit a control message in the communication process using batch data cher the first main channel by including a generator 159 main channel.

In connection with the use of packet data, the base station can transmit bit power control through direct primary channel to control the transmit power of the terminal. In this case, the controller 101 of the base station enters the bits of the power control in a specific position and passes them through direct main channel by including a generator 111 of the main channel.

To end communication using packet data, the controller 101 of the base station transmits the request signal to shut down the channel for an additional channel through direct primary channel by including a generator 111 of the main channel, and after reception of the request signal to shut down the channel, the controller 151 of the terminal transmits a shutdown signal channel to the base station through the reverse main channel by including a generator 159 main channel. In this case, a control message, which is transmitted through the main channel, has a frame size of 5 MS. By sharing request signal for call completion, additional channel, which is used in the current time for exchanging packet data, is released, and the main channel enters the state of conservation management. In the state corneal and to control the transmit power of the terminal by transmitting the control signal power at a particular time in a straight main channel.

As described above, when a control message is transmitted through the main channel and the data packet is transmitted via the auxiliary channel, the base station and the terminal allocate an additional channel for packet data services through the primary channel. After selection additional channel, the base station and the terminal communicates over a dedicated channel and transmits a control message via the primary channel, if the control message to be transmitted, is generated when performing services using packet data through an additional channel. In addition, when transmitting packet data through an additional channel, direct power control is performed using the main channel. After completion of the communication services using packet data, the base station makes a request for exemption channel through the main channel. In this case, an additional channel is released, thus completing the communication service using packet data, but the main channel supports the communication status. Preferably, a control message, such as message assignment/release channel, which is relatively short and has the switching of communication channels, has a frame size of 20 MS.

Fourthly, communication can be performed using the direct channel, which consists of a pilot channel signal of the main channel and the additional channel. In this case, the service voice communication is performed through the main channel and the packet data service is performed through an additional channel. In addition, the signal power control and another control message is transmitted through the main channel. In Fig.20B shows an algorithm for performing communication services using speech signals and packet data, the direct channel, and a direct communication channel consists of a pilot channel signal, the main channel and the additional channel.

When receiving a request signal to the communication of speech signals and packet data over a direct communication channel from the top-level base station controller base station 101 transmits a request signal of a channel number is assigned to an additional channel for the packet data service to the terminal through a direct channel by including a generator 111 of the main channel. Then, after receiving the request signal to the destination channel, the terminal transmits the confirmation signal to the base station through the reverse primary link by including a generator or frame is 5 MS. The base station then transmits the data packet through the designated direct additional channel by the generator 113 additional channel, and the voice signal is transmitted through direct primary channel by including a generator 111 of the main channel. In the direct channel of communication all control messages, which include the control signal power transmitted through the main channel.

Fifth, communication can be performed using a direct communication channel that consists of a pilot channel signal, a dedicated control channel and an additional channel. In this case, the control signal power, and other operating messages are transmitted through the dedicated control channel. In Fig. 19C shows the algorithm to perform communication services using packet data, the direct channel, where direct communication channel consists of a pilot channel signal, a dedicated control channel and an additional channel.

When receiving a request signal to the communication using packet data on direct channel of communication from the top-level base station controller base station 101 transmits a request signal to the selection of the channel for an additional channel through direct Vignale request destination channel, the terminal transmits the confirmation signal through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. In this case, a control message, which is transmitted through the dedicated control channel has a frame size of 5 MS. After receiving the confirmation signal, the controller 101 of the base station transmits packet data through a direct channel by the generator 113 additional channel. If you want to send the control message when the packet data service through an additional channel, the controller 101 of the base station transmits a control message frame 20 MS through direct dedicated control channel by enabling the generator 103 a dedicated control channel. Similarly, if you want to send a control message, when the service using packet data, via the selected channel, the terminal also transmits a control message frame 20 MS to the base station through a dedicated control channel by enabling the generator 153 dedicated control channel. To control the transmit power of the terminal in the process of implementing communication services using packet data, the base station is roller 101 of the base station enters the bits of the power control in a specific position and transmits them via a direct dedicated control channel by enabling the generator 103 of the selected channel.

In order to complete the service connection with the use of packet data, the controller 101 of the base station transmits the request signal to shut down the channel for an additional channel through direct dedicated control channel by enabling the generator 103 a dedicated control channel. After receiving the request signal to shut down the channel, the controller 151 of the terminal transmits a shutdown signal channel to the base station through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. In this case, a control message, which is transmitted through the dedicated control channel has a frame size of 5 MS. Through the sharing request signal to shut down the channel, extra channel, which is used in the current time to communicate packet data, is released, and a dedicated control channel status for conservation management. In the save state control, the base station may transmit a control message to the terminal through direct dedicated control channel and control the transmit power of the terminal by transmitting the control signal power at a particular time through direct vides additional channel and transmitting the control message via a dedicated control channel, the base station and the terminal allocate an additional channel for the packet data service through a dedicated control channel. After selection additional channel, the base station and the terminal perform communication using a packet data through a dedicated channel, and transmit a control message through a dedicated control channel, when the generated control message that you want to convey. Meanwhile, when the communication service using the packet data is completed, the base station executes the query on the release channel. Then an additional channel is released, thus completing the communication service using packet data, a dedicated control channel maintains its connection status. During transmission of the control message through a dedicated control channel control messages such as the message destination and the liberation of the channel that have a short frame size and should quickly be manipulated, transmitted in the frame of 5 MS, whereas the normal control message, such as message switching communication channels is transmitted in 20 MS frame.

Sixth, the connection can be made with the used channel and the additional channel. In this case, the signal power control and control messages that relate to the main channel, is transmitted through the main channel. In addition, control messages, which relate to the additional channel are transmitted through the dedicated control channel. In Fig.22B depicts an algorithm for performing voice communication services and packet data on the direct communication channel, where direct communication channel consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel.

When receiving a request signal to the communication service using speech signals and packet data from the top-level base station controller base station 101 transmits a control message for allocating channels to the terminal through a direct dedicated control channel by enabling the generator 103 a dedicated control channel. After receiving the control message for allocating channel, the controller 151 of the terminal transmits the confirmation signal to the base station through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. In this case, the control message is transmitted through a dedicated upray additional channel and transmits the voice signal and a control message to control the speech signal through direct main channel way "shaded command-and-pack" or "pause-and-pack". In the direct channel signal power control is transmitted through the main channel. As an additional channel is connected only when it has data to transmit, a situation may arise when you only connection without the connection of an additional channel.

Seventh, the communication can be performed using a direct communication channel that consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel. In this case, the voice communication service is controlled through the primary channel, and the service using the packet data is performed through an additional channel. In addition, the control signal power is transmitted through the main channel, and control messages relating to the main channel and the additional channel are transmitted through the dedicated control channel. In Fig.21B depicts an algorithm for performing communication services using speech signals and packet data, the direct channel, where direct communication channel consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel.

After reception of the communication request using speech signals and packetmedia set as the primary channel and an additional channel to the terminal through a direct dedicated control channel by enabling the generator 103 a dedicated control channel. After receiving the control message, the terminal transmits the confirmation signal to the base station through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. In this case, a control message, which is transmitted through the dedicated control channel has a frame size of 5 MS. The base station then transmits the voice signal through a direct primary channel, and the data packet through the direct channel by including a generator 111 main channel generator 113 additional channel. Control message in the direct communication channel is transmitted through a dedicated control channel, and the control signal power is transmitted through the main channel.

In addition, communication via a reverse communication channel can be performed through the seven ways, which are described below.

First, communication can be performed using the reverse communication channel that consists of a pilot channel signal and the main channel. In this case, all control messages are transmitted through the main channel using the method of "shaded command-and-pack" or "pause-and-pack". However, when communication is performed via a reverse communication channel, the signal power control usually transmits Tomo communication channel, where the reverse communication channel consists of a pilot channel signal and the main channel.

As a rule, to transfer the speech signal after a call to perform services normal voice communication via a reverse communication channel, the pilot channel signal and the main channel must be used in conjunction with a control channel signal transmission power control, however, in the present embodiment of the present invention, the control signal power is transmitted through the pilot channel signal so as to transmit the voice signal using a pilot channel signal, and the main channel without allocation of other channels. In comparison with the known system, in the system according to the present invention, uses a few less channels, thus enabling a reduction of the ratio of maximum value to the average value. As a result, compared to the prior art, the terminal may have a wider area of coverage even with the same power while reducing the complexity of the receiver.

When receiving a request signal of the normal voice communication via a reverse communication channel from the higher-level object terminal, the controller 151 of the terminal transmits a signal Zap the Oia request signal channel, the controller 101 of the base station transmits information, which relates to the appointment of the channel and the parameters that relate to adjacent cells in the terminal through a paging channel by the generator 109 paging channel. The terminal then transmits a confirmation signal to the base station by means of a generator 157 access channel after receiving the information on the allocation channel. After receiving the confirmation signal, the base station is prepared to receive the signals that come from the terminal through the main channel allocated by the generator 111 of the main channel, and the terminal transmits the voice signal to the base station through the main channel allocated by the generator 159 main channel. The base station and the terminal are sharing the speech signal through the forward and reverse fundamental channels, which are allocated using the generator 111 direct main channel generator 159 opposite the main channel, and transmit a control message except for signal power control by adding them to a voice data transmission method "shaded command-and-pack" or "pause-and-pack". In addition, to control the transmission power controller is nciu through the channel of the pilot signal by the generator 155 channel pilot signal. To complete the data transfer when performing voice communication through the selected primary channel, the terminal transmits a termination signal to transmit data to the base station by means of a generator 159 main channel, and after receiving the signal the end of data transmission, the base station transmits the confirmation signal to the terminal by means of a generator 111 of the main channel and terminates the voice communication by the United liberation main channel.

Second, communication can be performed using the reverse communication channel that consists of a pilot channel signal, a dedicated control channel and the main channel. In this case, all messages with the exception of the control signal power transmitted through the dedicated control channel. When communicating via a reverse communication channel, the signal power is usually transmitted through the pilot channel signal. In Fig.17A depicts an algorithm for performing services high-quality voice communication via a reverse communication channel, where the reverse communication channel consists of a pilot channel signal, a dedicated control channel and the main channel.

When receiving a request signal for high-quality voice communication via a reverse communication channel from the top-level object, the term
by including a generator 157 channel access. After receiving the request signal to the destination channel from the generator 157 access channel, the controller 101 of the base station transmits a signal destination channel through direct paging channel by the generator 109 paging channel. After reception of the destination channel, the terminal transmits the data through the main channel allocated by the generator 159 main channel, and, if necessary, transmits a control signal through a dedicated control channel by enabling the generator 155 dedicated control channel. In this case, the control message has a frame size of 20 MS.

To end communication in the implementation of services of high quality voice communication, the controller 151 of the terminal transmits a request signal to shut down the channel through the reverse main channel by including a generator 159 main channel. After receiving the request signal to shut down the channel controller 101 of the base station transmits a shutdown signal channel to the terminal through a direct primary channel by including a generator 111 of the main channel. The terminal then releases the channel at a particular time. Control message, which pilot signal together with the control signal power, and other control signals are transmitted through the dedicated control channel. Accordingly, the main channel allows you to send a control message to release only the primary channel and the speech signal, thereby improving the communication quality in comparison with the existing way voice communication for transmission of the control message using the method of "blackout command-and-pack" or "pause-and-package".

Thirdly, communication can be performed using the reverse communication channel that consists of a pilot channel signal, the main channel and the additional channel. In this case, all control messages, with the exception of the control signal power transmitted through the main channel. When communicating via a reverse communication channel, the signal power is usually transmitted through the pilot channel signal. In Fig.18A depicts an algorithm for performing communication services using a packet data via a reverse communication channel, where the reverse communication channel consists of a pilot channel signal, the main channel and the additional channel.

In the known communication system, you must use the channel pilot signal, channel, main channel and a control channel for transmitting packet data after use control message for an additional channel is transmitted through the main channel, in the known system, it is necessary to use a control channel for transmission power control. However, when communicating via a reverse communication channel, the system according to the present invention allows to transmit a signal power control via the pilot channel signal, so he could only transfer data packet via the auxiliary channel and only control messages through the main channel. In the system, the relevant prior art, four channel, i.e. the channel pilot signal, channel, main channel and a control channel used for transmitting packet data. However, in the present invention, the three channels, i.e., the pilot channel signal, the secondary channel and the main channel is used for packet data. Therefore, the communication system corresponding to the present invention, allows to reduce the ratio of maximum value to the average value through the use of several smaller number of channels compared with the known system and can also reduce the complexity of the receiver.

When receiving a request signal to the communication using packet data on the reverse channel from the top-level object terminal, the controller 151 of the terminal aqueous channel. The controller 101 of the base station then transmits the signal to the destination channel for the additional channel through which communication using a packet data through a direct primary channel by including a generator 111 of the main channel. In this case the used control message has a frame size of 5 MS. Providing an additional channel that was selected through direct primary channel, the controller 151 of the terminal transmits the data packet via the reverse channel by including a generator 161 additional channel. During packet data controller 151 of the terminal, if necessary, transmits a control message via the reverse main channel by including a generator 159 main channel. In this case, the control message is transmitted in this time, has a frame size of 20 MS. In addition, the controller 101 of the base station transmits packet data through a direct channel by the generator 113 additional channel and transmits, when necessary, control data through direct primary channel by including a generator 111 of the main channel. Control message that is transmitted in this time, that the La transmits the request signal to shut down the channel through the reverse main channel by including a generator 159 main channel, and after receiving the request signal to shut down the channel controller 101 of the base station transmits a signal to shut down the channel to the terminal through a direct primary channel by including a generator 111 of the main channel. In this case, a control message, which is transmitted through the main channel, has a frame size of 5 MS. By sharing request signal at the end of the channel, an additional channel, in which the current time is used for communication using packet data is released, but the main channel enters the state of conservation management. In the save state control, generator 155 reverse channel pilot signal transmitting power control with pilot signal at a specific point in time, and other control signals are transmitted through the main channel, which supports the connection status.

Fourthly, communication can be performed using the reverse channel, which consists of a pilot channel signal, the main channel and the additional channel. In this case, the service voice communication is performed through the main channel, and the service using packet data through an additional channel. In addition, managers soobsheniya signals and packet data on the reverse channel, where the reverse communication channel consists of a pilot channel signal, the main channel and the additional channel.

The pilot channel signal, a main channel, an additional channel and a control channel is usually necessary to use for voice and packet data communication services using speech signals and packet data on the reverse channel. However, in the present invention, the signal power control of the reverse link channel is transmitted through the pilot channel signal, so that an additional channel only transmits packet data, and the main channel only transmits the voice signal and a control message. Typically, four channel, i.e. the channel pilot signal, channel, main and control channels are used for transmission of voice data and packet data. However, in the invention for transmission of voice data and packet data are only three channels, i.e., the pilot channel signal in the main channel and the additional channel. Therefore, the communication system according to the present invention, allows to reduce the ratio of maximum value to the average value through the use of several smaller number of channels compared with the known communication system.

When taken with the and the upper level of the terminal, the controller 151 of the terminal transmits the request signal to the destination channel for an additional channel to the base station through the reverse main channel by including a generator 159 main channel. After receiving the request signal destination channel controller 101 of the base station allocates a channel to the target device via direct primary channel by including a generator 111 of the main channel. In this case, used a control message has a frame size of 5 MS. The controller 151 of the terminal then transmits the packet data through the reverse channel assigned by the generator 161 additional channel, and the voice signal through the reverse main channel by including a generator 159 main channel. In this case, the signal power control in the reverse link is transmitted through the pilot channel signal, and other control messages are transmitted through the main channel.

Fifth, the communication can be carried out using the reverse communication channel that consists of a pilot channel signal, a dedicated control channel and an additional channel. In this case, all control messages, with the exception of the control signal power transmitted through a dedicated upwash runs through the reverse channel. In Fig.19A depicts an algorithm for performing communication services using a packet data via a reverse communication channel, where the reverse communication channel consists of a pilot channel signal, a dedicated control channel and an additional channel.

Usually, for communication using packet data on the reverse channel, you must use the channel pilot signal, channel, main channel and a control channel for transmitting packet data after a call. Although most control messages for additional channels are transmitted through the main channel, known communication system must use a control channel for transmission power control. In the present invention, however, the signal power control of the reverse link channel is transmitted through the pilot channel signal so that the additional channel only transmits packet data, and a dedicated control channel only transmits control messages. While in the known communication system uses four channels, i.e., the pilot channel signal, an additional channel, the main channel and the control channel, in a new communication system uses three channels, i.e. channel pilot signal, channel and vidoemo value while using fewer channels in comparison with the known system, and also reduces the complexity of the receiver.

When receiving a request signal to the communication using packet data on the reverse channel from the top-level object terminal, the controller 151 of the terminal transmits the request signal to the destination channel through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. After receiving the request signal to the destination channel, the controller 101 of the base station transmits a signal channel number is assigned to an additional channel for communication using a packet data through a direct dedicated control channel by enabling the generator 103 a dedicated control channel. Control message that is used at this point in time, has a frame size of 5 MS. Then, the controller 151 of the terminal transmits the data packet via the reverse channel by including a generator 161 additional channel. If you want to send the control message when the packet data transfer, the controller 151 of the terminal transmits a control message having a frame size of 20 MS, through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. The controller 151 of the base stenciling channel, and a control message through a direct dedicated control channel by enabling the generator 103 a dedicated control channel when it is needed. In this case, the control message has a frame size of 20 MS. To control the transmit power of the base station in the communication process using batch data, the controller 151 of the terminal transmits a signal power control via the reverse link pilot signal.

For complete communication services using a packet data when the packet data transfer via the auxiliary channel and the control message through the dedicated control channel, the controller 151 of the terminal transmits a request signal to shut down the channel through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. After receiving the request signal to shut down the channel controller 101 of the base station transmits a shutdown signal channel to the terminal through a direct dedicated control channel by enabling the generator 103 a dedicated control channel. In this case, a control message, which is transmitted through the dedicated control channel has a frame size of 5 MS. Through the exchange request signal is the use of packet data, is released, and a dedicated control channel goes into maintaining state control. Able to maintain control of the generator 155 reverse channel pilot signal transmitting power control with pilot signal at a specific point in time, and other control signals are transmitted through the dedicated control channel, which supports the connection status.

Sixthly, communication can be performed using the reverse communication channel that consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel. In this case, a control message, which refers to the main channel, is transmitted through the main channel, and a control message, which is related to the additional channel is transmitted through a dedicated control channel. When communication is performed via a reverse communication channel, the signal power is usually transmitted through the pilot channel signal. In Fig.22A depicts an algorithm for performing communication services speech signals and packet data on the reverse channel, where the reverse communication channel consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel.

Usually the substance of the pilot channel signal, additional channel, main channel and a control channel for transmitting packet data after a call. In Fig.22A additional channel only transmits packet data, main channel only transmits the voice signal to be transmitted through the main channel, and a control message to control the speech signal, and the dedicated control channel transmits a control message to control channel. In the known system uses four channels, i.e., the pilot channel signal, an additional channel, the main channel and the control channel in order to transmit the voice signal and packet data. In the system according to the present invention also uses four channel, i.e. the channel pilot signal, channel, main channel and the dedicated control channel. However, in the known system, since the control channel has a low bandwidth, most of the control messages that are intended for additional channel, is transmitted through the main channel, thus decreasing the quality of the speech signal and packet data. System corresponding to the present invention, allows you to transfer bits of power control through the channel p is emanna command-and-pack" or "pause-and-package", and to transmit a control message that is intended for additional channel through a dedicated control channel. Therefore, in comparison with the known system, the new system improves the quality of voice data and packet data.

When receiving a request signal to a communication service using a packet data and voice signal from the object at the top level of the terminal, the controller 151 of the terminal transmits the request signal to the destination channel to the base station through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. After receiving the request signal to the destination channel, the controller 101 of the base station transmits a control message to assign additional channel through direct dedicated control channel by enabling the generator 103 a dedicated control channel. In this case, a control message, which is transmitted through the dedicated control channel has a frame size of 5 MS. Then the terminal 151 transmits the packet data through the reverse channel, which is allocated by the generator 161 additional channel, and transmits the voice signal and a control message to control the speech signal through the reverse is meant to control the speech signal, added to the main channel by using method "blackout command-and-pack" or "pause-and-pack" and then passed. The pilot signal in the reverse link is transmitted through the pilot channel signal, and other control messages are transmitted through the dedicated control channel. An additional channel is connected only when it has data to send; otherwise it is disconnected. Therefore, a situation may arise when communication is performed without connecting an additional channel. That is, the system may be in a situation where the reverse dedicated control channel is disconnected, and a voice message and a control message for voice messages are transmitted through the main channel.

Seventh, the communication can be performed using the reverse communication channel that consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel. In this case, the main channel provides only a voice service, and additional channel provides only packet data service. In this case, all control messages that relate to the main channel and the additional channel are transmitted through the dedicated control channel and the control signal communication channel. In Fig.21A depicts an algorithm for performing communication services using speech signals and packet data on the reverse channel, where the reverse communication channel consists of a pilot channel signal, a dedicated control channel, the main channel and the additional channel.

For voice and packet data after a call to communicate using speech signals and packet data on the reverse channel in the known system uses a pilot channel signal, a main channel, an additional channel and a control channel. In the present invention, however, the signal of the reverse power control channel is transmitted through the pilot channel signal. In Fig.21A and 21B additional channel allows you to send only packet data, the main channel is only the voice signal and the dedicated control channel is a control message. In the known system, it is necessary to use four channels, i.e., the pilot channel signal, an additional channel, the main channel and the control channel. The system according to the present invention allows the use of four channels, i.e., the pilot channel signal, a main channel, an additional channel and a dedicated control channel. However, as upravlyayu, intended for additional channel through the main channel, which degrades the quality of speech signal and packet data. In the present invention bits power control is transmitted through the pilot channel signal, and all control messages are transmitted through the dedicated control channel, thus improving the quality of the speech signal and packet data in comparison with the known system.

When receiving the communication request signal using the speech signal and packet data on the reverse channel from the top-level object terminal, the controller 151 of the terminal transmits the request signal to the destination channel for the main channel and the additional channel through the reverse dedicated control channel by enabling the generator 153 dedicated control channel. After receiving the control message, the controller 101 of the base station allocates an additional channel through direct dedicated control channel by enabling the generator 103 a dedicated control channel. In this case, a control message, which is transmitted through the dedicated control channel has a frame size of 5 MS. Then, the controller 151 of the terminal transmits packet data through the reverse channel to the Noi canal, which is released by the generator 159 main channel. The signal of the reverse power control channel is transmitted through the pilot channel signal, and other control messages are transmitted through the dedicated control channel.

It is shown in Fig.17A-22V communication system according to the present invention, enables you to independently use the channel for transmission of the control message when performing communication with a speech signal and/or packet data. That is, as shown in Fig.17A and 17B, for communications services using voice high quality signal, the speech signal is passed through the primary channel, and a control message is transmitted through a dedicated control channel. According Fig. 18A and 18B, for communication using a packet data #1, the packet data is transmitted via the auxiliary channel, and a control message is transmitted through the main channel. According Fig.19A and 19B, for communication using a packet data #2, packet data is transmitted via the auxiliary channel, and a control message is transmitted through the main channel. According Fig.20A and 20B, to communicate using voice and packet data # 1, the speech data and the control message are transmitted through the main channel, and counter the data #2, voice data is transmitted through the main channel, and packet data are transmitted via the auxiliary channel, and a control message is transmitted through a dedicated control channel. According Fig.22A and 22B, to communicate using voice and packet data #3, the speech data and a control message, which refers to the voice data transmitted through the main channel, packet data is transmitted via the auxiliary channel, and a control message, which refers to communication using packet data, is transmitted through a dedicated control channel. As described above, in the reverse channel signal power control is transmitted through the pilot channel signal. However, in direct communication channel signal power control is transmitted through the main channel when the primary channel is used, and through the dedicated control channel only when the main channel is not used. In Fig.17A-22V brackets [] indicate the state in which the control message and the data is transmitted at the same time.

In the table (see the end of the description) PC denotes the pilot channel, zook (PVOC) refers to ("direct") dedicated control channel OK primary channel and center channel.

Although the description of podrobnyi have reverse scheme of relative channel generators. Therefore, a detailed description of the channel receivers are omitted here.

The communication system according to the present invention includes a dedicated control channel (or another channel that allows you to function as a dedicated control channel) and transmits a control message, regardless of whether you use a dedicated control channel when the communication service using voice and packet data. In addition, the system allows you to send control messages that relate to the purpose of the channel, the main channel and/or an additional channel that will be used for a communication channel through a dedicated control channel, and transmits a control message, which refers to the connection during an active status through a dedicated control channel. With the release of call, though the channel is disconnected, the dedicated control channel supports the status control for transmission/reception of the control message. Therefore, in operational condition, when the channel has no data to send, the used channel is released and is only supported by a dedicated control channel. In addition, if the transmitted data is generated in the status of the maintenance pack is maintaining control is maintained over a predetermined period of time, the system continues to be in an unusable state and frees the allocated control channel. Accordingly, the system does not transmit a control message through the use of the channel, which allows to improve the efficiency of the orthogonal code.

In addition, because the signal power control is transferred to the terminal through a direct dedicated control channel, the system allows to solve the problem caused by the input bits of the power control. That is, when a control message is transmitted through the main channel, the signal power control designed for direct communication channel is transmitted by adding to the main channel, and when a control message is transmitted through a dedicated control channel, the control signal power, designed for direct channel, is transmitted by adding a dedicated control channel. Therefore, the system allows for reverse power control through the use of channel designed for transmission of the control message, and not used channel, thus allowing to improve the quality of communication.

In addition, a control message is transmitted when the frame length in accordance with the types of managers reported the influencers messages are relatively short and should quickly be transmitted. However, when sending a long text message, such as message switching communication channels, the system uses a long shot. Therefore, the control message can be effectively communicated through a dedicated control channel.
