The invention relates to a mobile communication system, in particular to a method of continuous transmission of user data on a reverse common channel in a mobile communication system released with a reverse dedicated channel. User data are divided into multiple segmented message, if the user data is longer than the data segment in the frame of the reverse common channel. Many segmented message is then passed to the data segments of consecutive shots on the reverse common channel. The method further comprises determining whether the base station is segmented messages by receiving a response message to the mobile station, showing the receiving segmented message from the base station. The common channel is preferably selected logical channel with power control. The technical result achieved by the invention consists in increasing the throughput of data transmission and reducing the time to reply and transmission delay of the data packet. 2 C. and 21 C.p. f-crystals, 11 ill.

The previous state of the art the Present invention relates in General to mobile communication system, and in particular to a method of the related technology, the Third generation (3G) IS-95 supports many data services in addition to standard voice devices, including the transmission of high quality speech, high-speed data, moving pictures and browse the Internet. In this system, mobile direct channel sent from the base station (BS) to mobile station (PS), and the reverse channel is directed from the SS to the BS. Channel search call (paging and access channel, usually called the common channels are used to transfer data between the BS 4 and BS 2 before you install voice conversation, as shown in Fig.10. BS 4 sends a message to the channel search of the call and receives a response message from PS 2 on the access channel. PS 2 sends a message on the access channel and receives a response message from the BS 4 channel search call. To use available multiple channels search call and access channels. Channels search call is typically modulated Walsh codes, and access channels modulated codes long.

3G IS-95 satisfactorily for voice communication, but can not fully guarantee the high quality of the connection for the packet data, where a large amount of packet data, including the long period signal and the waiting period is transmitted via RLP (Protocol Radio Channel - DAG), and short data packet is transmitted using RBP (Batch Rcih Data PKD) frame or to send another PKD frame, depending on the confirmation signal (ACK) or negative confirmation signal (NACK) is received for the previous transmitted frame PKD mode inactive frame 3G IS-95.

Thus, in the system 3G IS-95 RBP has a relatively low bandwidth, reliability and long response time related to under batch mode, because the PDP is performed in a batch sub-mode, the inactive mode, only with the reverse common channel. In fact, the process of sending a frame PKD, receive the response, and then make another frame PKD takes a long time, thus causing a large delay in the action of the communication packet data, to ensure that in the sense of reliability, response time and transfer rate.

Brief description of the invention in Order to achieve these and other objectives, a method of continuous transmission of user data on a reverse common channel in a mobile communication system without reverse dedicated channel. User data are divided into multiple segmented message, if user data is longer than the data segment in the frame of the reverse common channel. Many segmented message is then passed to segm the th, does the base station of the segmented message by receiving a response message indicating the receiving segmented message. Many segmented messages preferably loaded on the data segments of consecutive shots on the reverse common channel assigned as a logical dedicated channel with adjustable power.

Therefore, the aim of the present invention is to provide a method for continuous transmission of a long packet of a message on a reverse common channel.

Another objective of the present invention is the development of the method of performing the full duplex transmission schemes PDP, in which PKD message is continuously transmitted on the reverse common channel in under batch-mode Inactive mode.

An additional objective of the present invention is to develop a way to permit transmission of a long packet messages when the system performs power control on the designated reverse common channel in order to properly control the initial power of the access system to minimize response time and improve the throughput of the transfer.

A detailed description of the preferred embodiments
It should be understood that in the following description of preferred embodiments of the specific details set out to provide a more complete understanding of the present invention, despite the fact that experienced professionals can carry out this invention without these specific details. In addition, it should be understood that in the accompanying drawings similar reference numbers are used to denote elements having similar or equivalent structure. In the following description, well-known functions or constructions may not be described in detail because they litter this invention with unnecessary detail.

For a better understanding of the present invention will be described modes packet service communication system with reference to Fig.11. As shown, packet service consists of Zero batch mode, initialization mode, Active mode, hold control, suspend mode, the inactive mode and reconnect. The batch is tunes refers to the default mode to activate the batch service.

After a request packet service in the zero batch mode is attempting to join a packet service in the initialization mode. When you install a dedicated control channel - WOOK (DCCH), the initialization mode is transferred to the hold control. WOOK is required to initialize the GOK and ITL (Protocol point-to-point - ITL). In the active mode logical dedicated traffic channels - BKT (DTCH) are supported on the physical (direct and reverse) the Wookiees and frames GOK share on these channels. When there is a relatively short inactive period, the batch service enters the suspend mode in order to effectively use radio resources and reduce energy consumption of mobile stations. As a dedicated control channels released in suspend mode, both BS and SS reserve status information, assigning traffic channels, variable coding and the like, to facilitate the appointment of a dedicated control channels.

In suspend mode PS listens to the channel search call. After the appointment WOOK suspend mode is transferred to the hold control. If the package has not been received within a predetermined time in break mode, osushestvlyaetsya mode, in which the batch service control channels and traffic and the GOK released, and is only supported by ITL. Inactive mode goes to zero the batch mode, if the PTT is released.

Fig.1A and 1B are block diagrams that illustrate how the preceding technique steps substation to send the message, PKD and actions BS for receiving messages PKD on the reverse common channel in under batch-mode inactive status in accordance with the Protocol 3G IS-95. After PS 2 sends a frame PKD on the reverse common channel (i.e. the channel access), the reception of the confirmation signal, the ACK from the BS 4 channel search call indicates a successful transfer. Repeated negative reception confirmation signal NACK or absence of reception of a response message from the BS during a predetermined time (i.e., until the timer TPC) shows the transmission fails. BS 4 checks the CRC (Cyclic Code Redundancy - ICC) frame PKD adopted on the reverse common channel (access channel) to decide whether to send the confirmation signal, the ACK or a negative acknowledgement signal NACK to direct channel search call.

Continuing reference to Fig.1A and 1B, note that PS 2 sends a frame ASM on the reverse common channel, and sets t checks CKN frame PKD in step 114 and determines the presence or absence of errors in the frame PKD and step 116. If the generated signal errors ICC, BS 4 sends to PS 2 the confirmation signal, the ACK indicating successful transmission on the channel search of the call in step 118. If errors were detected ICC, BS 4 sends to PS 2 signal negative acknowledgement or NACK message indicating a distorted transmission, in step 120.

PS 2 determines if the signal (ACK or NACK) prior to the expiration time of the timer TPC in steps 102 and 104, respectively. After receiving the confirmation signal, the ASA PS 2 determines whether there is another frame PKD, which should be sent, in step 106. If it has, the procedure returns to step 100. Otherwise, the procedure ends.

Otherwise, if the received confirmation signal or NACK message indicating the transmission has failed, prior to the expiration time of the timer TPC, or any of the signals ACK, or NACK message indicating a failed transmission is not received before the expiration time of the timer T_NACK in steps 102 and 104, PS 2 re-transmits the same frame PKD and resets the timer TPC in step 110. Then, the procedure returns to step 102.

Fig. 2 is a diagram illustrating the method of the preceding techniques to exchange messages between the BS 4 and BS 2 with Fig.1A and 1B on the basis of this Protocol.

One mapleseed PDP described above. To describe how the usual scheme of transfer of the PDP is modified according to the present invention requires some explanation concerning the appointment of a common channel and power control assigned to the common channel.

A well known example of a General purpose channel is described in Korean patent application N 1998-13149, registered on April 13, 1998, entitled "apparatus and method for transmitting messages common channel in a CDMA communication system" Ki-sung Jung and other Detailed description of the power control assigned channel can be found in Korean patent application N 1998-14276, registered on April 14, 1998 and entitled "power Control of the reverse common channel in a CDMA communication system" Jin-Woo Choi, etc.

Assigning a common channel (see Korean patent application N 1998-13149) refers to the process of designating a reverse common channel as a dedicated (hereinafter assigned to a common channel) in the logical sense of the term, is generated when the message is longer than one frame, so as to continuously convey this long message. More specifically, after generation of the message that should be sent, the PC 2 determines whether this message is sent at one time. If it can be used, the usual scheme is the message" and "the flag of the request destination of the frame are mounted to the frame transmission to the BS 4. After receiving the frame BS 4 checks the flag of the message and the request flag of the destination. If they reset, BS 4 resets the flag of the destination and sends a confirmation to the PS 2. If any of the flags additional message or request destination is selected, the BS 4 determines whether there is a channel that can be assigned, and if he has, it assigns this channel. BS 4 sets the maximum duration and the priority for the selected channel, if necessary, and sends a confirmation message to the PS 2.

Will be given an explanation regarding the management of capacity assigned to a common channel (see Korean patent N 1998-14276). Since BS 4 receives frames SDB continuously, the message sent by the base station BS 4, must include information relating to the previously described assignment channel, such as whether to perform power control, the number of Walsh code shared control channel capacity and location (i.e., the index of the segment) control signal power, if power control is performed. After a predetermined time after BS 4 sent a response message to request a channel number is assigned to PS 2, it sends a signal to power control in a pre-opoly preamble on the channel, assigned to the response message within a predetermined time, and adjusts the transmit power between the BS 4 and BS 2. PS 2 sends a message to transmit to the BS 4 on the designated common channel at a predetermined time later. While BS 4 receives a message from PS 2, it continuously adjusts power by sending the control signal power common channel power control.

PDP for continuous transmission of messages PKD can be performed in accordance with the described embodiments of the present invention, if the above-described channel requirements for the appointment of a common channel and power control assigned to the common channel are satisfied.

The implementation of the PDP for the continuous transmission of frames PKD according to embodiments of the present invention requires the frame PKD, as shown in Fig.3A, and the response frame for the received message, as shown in Fig.3V. Frame PKD and the response frame is sent PS 2 and BS 4, respectively.

In Fig.3A frame PKD consists of user data fields PKD 10, the field sequence is transferred to the PKD 12 and a field flag additional messages 14. Field sequence transmitted PKD 12 provides the serial number of the frame PKD, which should be the third for the current frame PKD.

In Fig. 3B response frame consists of reply fields 20 fields and sequence adopted PKD 22. Field response 20 informs PS 2 about the presence or absence of errors in a received message using the signal ACK or NACK. The sequence field of the received PKD 22 provides the serial number of the current received frame PKD. Field sequence transmitted and received PKD 12 and 22 contain the same bits.

Message PKD is transmitted continuously in one or two ways, depending on the response from the BS 4: signal NACK is sent only if BS 4 defines errors; and the signal ACK or NACK is sent for each frame PKD, taken from PS 2.

Fig. from 4 to 6 illustrate the first embodiment of the scheme of continuous transmission of the PDP according to the present invention. Figures from 7 to 9 illustrate a second embodiment of the scheme of continuous transmission of the PDP.

First embodiment
Fig. 4A is a diagram illustrating the transmission/reception of messages and the operation of the error correction after receiving the NACK signal in accordance with the first embodiment of the transmission schemes of the PDP, where the NACK signal is transmitted only for frame PKD with errors. PS 2 accepts the message, as shown in Fig, 3B, BS 4, while PS 2 sends frames PKD continuously desig which detects the frame PKD, have errors by checking the field sequence adopted PKD 22 response message, and retransmits the corresponding frame PKD. When continuous transmission of the PDP is completed, the BS 4 frees assigned a common channel with power control, and then re-assembles the received frames PKD on the basis of sequence PKD, to build a complete message PKD.

Fig. 4B is a diagram illustrating the operation of error correction when the PS 2 does not receive a NACK signal due to the propagation conditions of radio waves. If the frame PKD obtained from PS 2, contains errors, the BS 4 sends a response message containing the NACK signal and a corresponding sequence number of the received PKD, and sets the timer T_NACK. If the frame PKD, corresponding to the accepted serial number, CRP, is not received from the substation 2 during the period T_ NACK, the BS 4 considers the NACK signal as a lost and retransmits the NACK signal. PS 2 determines that the frame PKD was successfully transmitted, if PS 2 does not receive a NACK signal. PS 2 retransmits the frame PKD, the corresponding serial number of the received PKD response message NACK only when it receives a NACK signal from the BS 4. When the scheme of continuous transmission of the PDP is completed thus, B is based on the sequence PKD, to provide a complete message PKD.

Fig.4C is a diagram illustrating the operation of error correction, when initiated by the SS frame PKD lost in the transfer process. BS 4 receives a frame of PKD and checks the flag field additional messages 14 of the frame PKD. If the flag field of an additional message 14 is installed, BS 4 sets the timer T PKD and waits for the next frame from the substation 2, If BS 4 does not receive the next frame PKD prior to the expiration time of the timer TPCD, BS 4 sends to PS 2 response message with a field of the response set in the NACK, and the field sequence adopted PKD set in the sequence number following the serial number transmitted PKD the last accepted frame PKD, which was initiated by the PS for the first time. PS 2 considers the transfer of his initiated messages successful if it does not receive a NACK signal. When the scheme of continuous transmission of the PDP is completed thus, the BS 4 frees assigned a common channel with power control, and then re-assembles the received frames PKD on the basis of sequence PKD, to provide a complete message PKD.

Fig.5 and 6 are block diagrams of the operation of SS and BS schemes for data exchange in accordance with the described embodiment the reading transmission PKD, a of Fig.6 is a block diagram of the operation of the base stations in accordance with the second embodiment of the scheme of continuous transmission PKD.

Referring to Fig.5 and 6, after generation of the message PKD, which should be sent, in step 200 in Fig.5 PS 2 determines whether the message PKD two or more frame in step 202. If the message PKD is a single frame, this message PKD is sent to the BS 4 in accordance with the usual scheme of transfer of the PDP. If the message PKD should be sent in two or more frames, PS 2 requires the allocation assigned to the common channel from the BS 4 in step 206.

Upon receipt of the request on the designated common channel in step 300 of Fig.6 BS 4 determines whether there is available to the designated channel in step 302. If the request cannot be confirmed, BS 4 sends to PS 2 message with the reset flag of the destination in step 304. If it can be confirmed, BS 4 distributes assigned a common channel with power control, and sends a message to PS 2, containing the set flag of the destination in step 306.

PS 2 determines whether the flag of the destination of the message received in step 208. If it is not installed, PS 2 resumes the request for the appointment of a common channel in step 206. If the flag of the destination of the received message is set, PS 2 divides the message PKD on the spacecraft. In step 212 PS 2 sets the flag field additional messages 14 marks and serial number of PKD in the field sequence transmitted PKD 12. If should be sent to the last segment of PKD, the flag field of an additional message 14 is reset. PS 2 determines if the response message from the BS 4, in step 214. If the response message is not received, the PC 2 sends a frame PKD, including bulleted flag messages, and the serial number transmitted PKD, and user data PKD to the BS 4 on the designated common channel power control in step 216. Then PS 2 determines whether the current sent to the frame PKD last, in step 218. If not, the procedure returns to step 210.

Meanwhile BS 4 determines if the frame PKD in step 308. Upon receipt of the frame PKD, BS 4 checks the CRC of the frame PKD and determines whether it contains an error, in step 310. If there are no errors, the BS 4 determines whether the received frame PKD retransmitted PS 2 on the NACK signal, in step 312. If he passed the first time, the BS 4 determines whether the flag of the message frame PKD, in step 316. If the flag of the message is set, the BS 4 sets the timer TPCD to correct errors, if the next frame PKD which determines, expired if a timer T_NACK. The timer _NACK is set to send the NACK signal from the BS 4, and, thus, is not used when the frame PKD adopted normally. If the timer T_NACK has not expired, the BS 4 returns to step 308.

In accordance with embodiments of the present invention BS 4 does not send a response message, if the frame PKD adopted successfully. For Example, In Fig.4A shows that BS 4 does not send a response message to be successfully received frames PKD (1), (2) and (4). Here (1), (2) and (4) indicate the serial frame numbers PKD.

Returning to Fig. 6, if a received frame PKD error was discovered ICC in step 310, the BS 4 sends a NACK signal to the PS 2 in step 320. That is, the serial number of the frame PKD, contain errors, be marked in the sequence field of the received PKD 22 from Fig.3B, and the NACK signal is marked in the reply field 20. As an example, if the frame PKD (3) contains errors, the BS 4 sends a response message containing the signal NACK (3) in Fig.4A. BS 4 sets the timer T_NACK in step 322 to determine the acceptance period, when the NACK signal is not reliably sent to PS 2, as shown in Fig.4V.

Upon receiving the response message including the signal NACK (3), from the BS 4 PS 2 checks the sequence field of the received SDB 22 response message in step 221. the 4 is not necessary to send a signal ASC (3) for the retransmitted frame PKD (3) PS 2, as for PS 2 to determine if the signal ACK (3) before the timer TPC has expired. For example, even if BS 4 does not send the response message for the retransmitted frame PKD (3) until the expiry of the timer TPC, PS 2 believes the transfer is successful.

If PS 2 does not receive a response message including the signal NACK (3), PS 2 considers the transmission of the previous frame PKD successful and sends the next frame PKD to the BS 4. If the frame PKD, which was generated signal NACK is not received before the expiration time of the timer _NACK in steps 308 and 328, BS 4 re-transmits the NACK signal to the PS 2 in step 330. Then BS 4 resets the timer _NACK in step 332. It Is Evident From Fig.4B can be noted that BS 4 re-sends the signal NACK (3) PS 2, when the timer T_NACK has expired.

Meanwhile, if the BS 4 receives a frame PKD prior to the expiration time of the timer T PKD in steps 308 and 324, it sends to PS 2 response message containing the NACK signal and a sequential number following the last accepted frame PKD, which was transferred from PS 2 for the first time, marked in the sequence field of the received PKD 22, in step 326. BS 4 sets the timer T PKD in step 318 and goes to step 328. Referring to Fig.4C, when the timer TPCD has expired, the BS 4 sends a NACK signal (4), shooteth.5 PS 2 determines whether the current frame is the last, and in step 224, it sets a timer TPC. Then PS 2 determines if the response message from the BS 4 in step 226.

On the other hand, if the BS 4 receives the last frame of PKD (flag message reset) in step 314, it sends a response message including the signal ASC showing PS 2 the completion of the reception in step 334. BS 4 frees assigned a common channel with power adjustment in step 336 and re-assembles the received frames PKD, to provide a complete message PKD in step 338.

If PS 2 does not receive the response message prior to the expiration time of the timer T PDP in steps 226 and 227, it retransmits the last sent frame PKD in step 238. Upon receipt of the response message PS 2 determines whether the field response 20 response message confirmation in step 236. In case of a negative acknowledgement PS 2 retransmits the last transmitted frame PKD in step 238.

If the message that was received during the time duration of timer TPC, is not a response message for the most recently sent messages in steps 226 and 228, the PC determines whether the field response 20 response message in the ACK in step 230. If the reply field 20 is installed in the NACK, PS 2 plot of the em frame PKD, corresponding to the selected serial number to the BS 4 in step 234.

The second embodiment of the
Will give a description of the second embodiment of the transmission schemes of the PDP with reference to figures 3A and 3B, figures 7A, 7B and 7C and figures 8 and 9. In the second embodiment of the signal ACK or NACK is generated for each frame PKD obtained from substation 2.

Fig.7A is a diagram illustrating the exchange of data and the operation for the correction of errors after generation of the NACK signal in the second embodiment of the transmission patterns of the PDF, where the signal ACK is generated for error-free frame PKD, and the NACK signal is generated for the faulty frame PKD. PS 2 receives the response message from the BS 4 during the continuous frame transmission PKD on the reverse appointed General channel with power control. If the response message contains the NACK signal, PS 2 allocates the frame PKD containing the error by checking the field sequence adopted PKD 22 response message and re-transmits the corresponding frame PKD. When the scheme of continuous transmission of the PDP is completed, the BS 4 frees assigned a common channel with power control and re-assembles the received frames PKD on the basis of sequence PKD, to provide a complete message PKD.

Fig. 7B is a diagram illustrating the operation korrekturen radio waves. PS 2 sends a frame PKD and sets the timer TPC. If the signal ACK or NACK with a serial number of the sent frame PKD is not received before the expiration time of the timer TPC, PS 2 believes that this frame PKD contains errors and re-transmits the frame PKD. Alternatively, PS 2 determines whether to pass the re-frame PKD by setting the timer TASK to check the response from the BS 4. When the scheme of continuous transmission of the PDP is completed thus, the BS 4 frees assigned a common channel with power control and re-assembles the received frames PKD on the basis of sequence PKD, to provide a complete message PKD.

Fig. 7C is a diagram illustrating the operation of error correction, when initiated by the SS frame PKD is lost during transmission. BS 4 receives the frame PKD and checks the flag field of an additional message frame 14 PKD. If this flag is set, the BS 4 sets the timer TPKD and waits for the next frame PKD from substation 2. If no frame PKD is not received before the expiration time of the timer TPCD, BS 4 sends to PS 2 response message including the NACK signal and a sequential number following the transmitted sequence number of the last received frame PKD. This error correction can be violi transmitted frame PKD lost and retransmits the same frame PKD. When the scheme of continuous transmission of the PDP is completed thus, the BS 4 frees assigned a common channel with power control and re-assembles the received frames PKD on the basis of sequence PKD, to provide a complete message PKD.

Fig.8 and 9 are flowcharts illustrating the operation of the substation and the work of the BS for the exchange of messages described with reference to Fig. 7A, 7B and 7C. Work TS in Fig. 8 is the same as in Fig.5, since the signal ACK or NACK is detected by checking the field response 20 response message received from the BS 4. That is, steps from 200 to 238 of Fig.5 is almost identical to steps 400 to 438 of Fig.8. Work BS in Fig. 9 differs from that of Fig.6 the fact that the added step of sending a signal ASC, because the signal ACK or NACK is sent for each received frame PKD. That is, the response message including the signal ASC and noted the serial number received PKD, is sent in step 511.

As described above, the present invention advantageously minimizes the response time and increases the throughput of transmission by allowing the transfer of the PDP data length of the packet, when the power control is performed on the designated reverse common channel to appropriately adjust the initial capacity of the access to the VNO be transmitted in suspend mode, as well as in inactive mode without initializing the GOK, which is performed by assigning the control channel at the transition from the inactive mode or suspend mode to the hold control or active mode. As a result, the response time and, thus, the transmission delay of the data packet can be reduced.

Although the present invention has been described in detail with reference to specific embodiments, they are merely illustrative applications. Thus, it should be quite clear that many changes may be made by experienced specialists within the framework and essence of the present invention.
