The LEVEL of TECHNOLOGY

The technical field to which the invention relates.

The invention relates in General to wireless communication and more specifically to controlling the speed of data transmission in the wireless communications system.

The level of technology

Wireless communication systems are used for many applications, including, for example, paging data transmission, wireless local telephone line (WLL, BLL), Internet telephony, wireless telephony and satellite communications systems. Example applications of wireless telephone system is a cellular telephone system for remote subscribers, who are often mobile. In a typical cellular telephone system, mobile subscribers or mobile stations transmit and receive signals from different base stations within the wireless network infrastructure of the communication system, during the movement of the mob is through the station.

Modern wireless communication systems such as cellular telephone, typically designed so that allow for multiple users or subscribers access to the shared communication environment. Various technologies have been developed for such wireless communication systems, multiple access, including multiple access, code division multiple access (CDMA), multiple access with time division multiplexing (TDMA) and multiple access frequency division (FDMA). In accordance with such multiple access technologies encode, modulate, decode and demodulated signals transmitted and received between many users and infrastructure wireless network, providing, thus, simultaneous communications between multiple users and providing a relatively large bandwidth for communication systems.

In the wireless communication system based on CDMA available range of radio frequencies (RF) is effectively shared across multiple users. In wireless communication systems typically transmit a voice message and recently also become available systems with advanced capabilities for providing data transmission services. An example of such communication systems that provide data transmission services, may represent the priority system high speed data (HDR, VSP), which corresponds to the specifications of the Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA) cdma2000 High Data Rate Air Interface Specification IS-856, January 2002 (the standard IS-856).

In the wireless communication system, such as a system based on CDMA or other mentioned technologies, multiple access, users are often mobile. While driving, users can move outside the service area of a sector of the base station or outside the service area of the base station. When the user, often called mobile subscriber or mobile station that is in a different service area or out of them so that when the user goes from one service area and enters another, to perform communication technique known as transfer. When the transfer of the mobile station starts to communicate with the sector of the base station, for simplicity referred to here as the base station in the service area, which includes the subscriber, and stops communicating with the base station in the service area, which he leaves. Using a technique called "soft transfer", during the transfer of a mobile station is simultaneously connected with two base stations. In other words, the mobile subscriber maintains communications with the base it is, the service area of which the mobile subscriber leaves, simultaneously establishing communication with the base station in the service area to which it belongs. When using this technology, both the base station together or independently decode the transmission of mobile stations. Communication with both base stations during soft transfer service reduces the chance of losing the call or other unintentional disconnection.

The data rate that can be supported by each of the two base stations involved in the transmission of the service may be different, for example, due to the overload level of the corresponding base station. The overload level in the system can be determined by monitoring the transmission rate of user data and power signal required for obtaining the desired quality of service (QoS TO). The communication channel from the mobile service to the base station is referred to as reverse link or upward communication channel. In a wireless CDMA system throughput reverse communication channel is limited by the level of mutual interference, and one measure of the extent of the congestion cell is the total received power above the level of thermal noise of the base station. The total received power over the level of thermal noise is usually called "rise over thermal noise is m" (ROT, VTS) and corresponds to the load of the reverse link. Typically, you want to keep ROT at the level close to the specified value. If the ROT is too high, the service area of the cell, i.e. the distance at which you can communicate with the base station of the cell is reduced, and the reverse communication channel becomes less stable. The reduced service area (for example, due to excessively high values ROT) can adversely affect the data rate that can be supported in the cell, and the mobile stations located in a cell boundary, it may lose the call. The service area of the cell decreases at high value ROT because of the increased amount of energy transmitted to the mobile station to provide the required level of energy in the base station. Typically, mobile subscribers are limited to some extent by the level of transmitted energy which they possess, and thus, the requirement of increasing the transmit power corresponds to a decrease in range. Low value ROT may indicate that the reverse channel is not heavily loaded, which indicates that potentially can increase the speed of data transmission is not used.

If the base station and the mobile subscriber involved in the transmission of the service, can support asnie data transfer rate, then the data rate of the mobile station during transmission of the service may not be optimal. For example, if a base station that performs transmission to mobile services, can support a higher data rate than is currently being used by the mobile subscriber, then the mobile subscriber may run at a lower data rate than is possible, and this can cause inefficient use of system resources. If the base station which transmits a mobile subscriber may not maintain the same high speed data transmission, which operates a mobile subscriber, then the mobile subscriber can create an increased level of interference to other users and can degrade system performance. Form of speed control data in the soft transfer service can be achieved by coordination between base stations. However, coordination between base stations through infrastructure or a channel of direct communication between base stations can be slow, or between two base stations may not be matching.

Thus, in the art there is a need to improve the speed redistributable Yes the data during transmission service in a wireless communication system.

The invention

Disclosed here are the options exercise aimed at solving the above problems by using method and device for controlling data transmission rate in the wireless communication system during a transmission service. The transmission of the mobile station receive and decode multiple base stations that are in the list of the transfer of the mobile station. Any base station in the list transmission service that successfully decodes the message, transmits to the mobile station an acknowledgement of reception information in a top-down communication channel. The mobile station then determines the control command data transfer rate on the basis of signals transmitted from base stations, which include a confirmation message. The mobile station adjusts its data rate in accordance with the speed control.

In another aspect, base station, which is not the base station that has transmitted the confirmation message, you may want to send the mobile station a command to establish the required data transfer rate. The base station that needs to transmit a command to establish a data transfer rate, can be a primary base station, which has a certain quality of service (QS) and other scheduling information, or the base station may be a non-primary base station, which is heavily overloaded and you want to reduce the data rate. The mobile station may then use the command to establish the required data transfer rate when determining the data transfer rate on the basis of the command speed of data transfer from the primary base station and of a non-primary base stations.

Control of the rate of data transmission in the wireless communication system during transmission of the service may include receiving the transmitted messages from the multiple base stations, the subsequent determination of multiple control commands data rate of the respective received messages from the multiple base stations. Control commands data transfer rate can then be combined, allowing you to adjust the speed of data transmission in accordance with the combined teams of the speed control. In the case of automatic repeat request (ARQ, APL), neperegruzhayte base station when the transmission service can decode the transmitted data independently and asynchronously transmit the acknowledgement (ACK). Asynchronous transfer ACK leads to synchronization problems when sending commands to control speed. The base station that does not support the transfer of CK, can not send the command speed control that can be interpreted as the state of the HOLD the hold command speed control. Aspects of this scenario is described that effectively provides a combination of control commands speed when the transmission service when receiving the ACK from a variety of uncoordinated base stations.

Combining commands speed control may include the use of weights to the received control command speed. For example, the command speed control of the primary base station may be assigned a greater weighting factor than the teams from a non-primary base stations. Combining commands data transfer rate may also include the establishment of a command speed control based on the required quality of service for the primary base station to the primary base station is operated to increase the speed of data transmission and a non-primary base station would provide control over the rate of data transmission based on the degree of loading of the system.

An additional aspect of the combination of control commands speed data transmission from multiple base stations involves reducing the data rate, if at least one of command data rate e.g shall go to reduce the data rate. Another aspect of the combination of control commands data rate includes maintaining the data rate, if none of the teams establish the data transfer rate is not indicated by a reduction in data rate and at least one of the teams setting the data transfer rate is a team maintain the speed of data transmission, for example, if the command to establish the data transfer rate is a zero command. Another aspect of the combination of control commands data rate includes maintaining the data rate, if none of the teams the data transfer rate is not aimed at reducing the data rate, increasing the data transfer rate or not is a command to maintain the speed of data transfer, but instead represents a different command, such as a null command. Another aspect of the combination of control commands speed includes increasing the speed of data transfer, if none of the teams the data transfer rate is not aimed at reducing the data rate or is not a command to maintain the data rate and at least one command data transfer rate is to increase the data transfer rate.

Detailed description of the invention

The word "exemplary"as used here, means "serving as an example, a case or illustration". Any variant of implementation, described herein as "exemplary"is not necessarily should be considered as preferred or having an advantage over the other variants of implementation.

Figure 1 shows part of the system 100 connection constructed in accordance with the present the invention. The communication system 100 includes infrastructure 101, many wireless communication devices (WCD) or mobile stations (MS, MS) 104 and 105, and devices 122 and 124 links on landlines. In General WCD can be either mobile or fixed, and the term "WCD" will be used as a term that replaces "MS" and "mobile subscriber", and Vice versa.

Infrastructure 101 includes components such as base station 102, the controller 106 of the base station, the centers 108 mobile switching public switched network 120, etc. In one embodiment, the base station 102 is integrated with the controller 106 of the base station, and in other embodiments, the base station 102 and the controller 106 of the base station are separate components. Different types of switched networks 120 can be used to route signals in the communication system 100, for example, circuit-switched network 120 may be a public switched telephone network (PSTN, UNTOC).

The term "direct channel" denotes a path of the signal from infrastructure WCD 101 to 104, 105, and the term "back-channel" denotes a path of the signal from the WCD to the infrastructure. As shown in figure 1, WCD 104 and 105 receives signals 132 and 136 of the direct channel and transmits signals 134 and 138 via a reverse communication channel. In General, the signals transmitted from the WCD 104 and 105 are for preamature the communication device, such as another remote module, or device 122 and 124 ground line, respectively, and they are sent via the public switched network 120. For example, if the signal 134 is sent from the initiator WCD 104, is designed to receive WCD 105 destination, this signal is sent through the infrastructure and the signal 136 is passed in the direct channel in the WCD 105 destination. Typically, a communications device, such as WCD, or device landlines can be both the initiator and the destination for the signals.

Examples WCD 104 include cellular phones, personal computers with wireless communication and personal digital assistants (PDAs) and other wireless devices. The communication system 100 can be designed so that it will support one or more wireless communication standards. For example, the standards may include standards such as TIA/EIA - 95-B (IS-95), TIA/EIA - 98-C (IS -98), cdma2000, Wideband (broadband) CDMA (WCDMA), and others.

Figure 2 shows a block diagram illustrating WCD 202 during the transfer service between the two base stations 204 and 206. As shown in figure 2, the device 202 WCD is associated with two base stations 204 and 206. In this illustration, the primary base station 204 (BS1) is a base station in a service area which is currently WCD 202, and a non-primary base stance (BS2) is a base station, in the service area of which includes WCD 202.

Project third generation partnership 2 (3GPP2), which is a cooperation project for the installation specifications for communication systems, third generation (3G), representing the interests of North America and Asia, developing global specifications for the development of a network of inter-system operations cellular radiotelecommunication ANSI/TIA/EIA-41 third generation, has received proposals to develop technology to control the rate of data transfer from one or more base stations during transmission services. In accordance with these proposals, the base station that manages WCD transmits a special control command transmission speed (bit tristate), which can be one of UP, HOLD or DOWN (UP, HOLD or DOWN), which means an increase, hold or decrease the speed or traffic to the pilot signal at the next transmission. If the WCD is in a state of mild transmission service, team management transmission speed can be taken from different base stations. Team management transfer rate from different base stations can be combined to produce effective team management data transfer speed. The drawback of this approach is evident when the base station and WCD use technology is AI, called hybrid automatic request for retransmission of the data (HARQ, GASM), to improve the performance of the system. When enabled HARQ mode, the mobile station transmits the same or another encoded copy of the same package, while the base station confirms the transfer package. The mobile station transmits a new packet with a new data transmission rate only when it successfully passes the previous packet or transmit the previous packet the maximum number of times. Mobile station successfully transmits a packet if it receives the acknowledgement (ACK)at least one base station from the list of soft transfer service. Due to this, the base station in the soft mode of transmission service transmits a command to control the speed UP or DOWN, only when it has successfully decoded the packet, and transmits the ACK is a direct acknowledgement channel (F-ACKCH, P-KODT) base station. The team HOLD corresponds to the absence of channel transmit speed control and allows you to save energy when the base station is not waiting for a new transmission from the mobile station. Because the quality of the transmitted messages received from different base stations may be different, not all base stations from the list of soft transmission maintenance mobile stations transmit ACK to the mobile subscriber, the simultaneity is temporal. The approach of the special control data transfer speed, which works without HARQ may be re-defined in the system, which is simultaneously used as a soft transfer between different base stations, and HARQ to improve performance. In the variant example of implementation of the WCD monitors direct channels speed control (F-RCCH, P-COWES) base station when it receives a message (ACK) to confirm by direct acknowledgement channel (F-ACKCH) from the base station. The problem with this approach may occur if the WCD 202 is in a state of mild transmission service with the primary base station 204 and a non-primary base station 206, and WCD 202 receives the ACK only from a non-primary base station 206. Even though 204 is the primary base station and can take more power interference from WCD 202, region base station 206 may decode the transmission of the mobile station and to transmit the control command speed transmission with ACK, which asks that WCD 202 has run UP against its data transfer rate. If this occurs, the primary base station 204 may not be able to control the data rate WCD 202 using the speed control.

The exception to this rule happens after is eredane last transmission, corresponding to the data packet, at this time WCD monitors all F-RCCH, which are assigned to the WCD, regardless of whether the WCD command ACK from BS or not. However, this scheme is very sensitive to errors in transmission of control signals, including errors reverse control channel packet data (R-PDCCH, COPD) and errors of direct acknowledgement channel (F-ACKCH). For example, the R-PDCCH contains the management information indicating the speed of data transmitted on the data link/packet number packet (also called a number subpackage). The number subpackage denotes the number of times the package has been passed, and he could not successfully decoded at the base station. If the number subpackage equal to the maximum number of allowed transmissions, then the current transmission channel is a last transmission for proper delivery of the package in BS. If the BS is unable to decode the transmission of the R-PDCCH from the WCD, then the BS will not have information about what the subpackage represents the last subpackage and that MS should transmit indicator speed control. MS will interpret the absence of a transmission channel (F-RCCH as command HOLD (hold). The HOLD does not allow WCD to increase the data rate, even if that BS did not intend to send a team HOLD, and can support traffic with a higher speed transfer of data is X.

In another embodiment, the mobile station monitors the control command data rate only from the primary base station. In this approach, a non-primary base station can accept mutual interference from the mobile station, and do not have the ability to manage mobile station. In addition, the mobile station is moved, it can be within the service area of another base station, and can switch between cells. During the switching between cells in MS is associated with the primary BS1 204, transmitting a preset number of frames of the switch, indicating that a non-primary BS2 206 will be the primary base station. Switching between base stations is pumped when the MS receives the indicator of the completion of switching from the old primary BS1 204 or will be sent when the specified number of frames switch. The operation of the speed control data from the primary base station is not explicitly defined in the interval switching. Below are some different techniques that you can use during the soft transfer service and switching between cells, which presents various problems, along with solutions to these problems.

Case 1

In this embodiment, a mobile station (MS) prinimaetsea acknowledgement (ACK), transmitted by the base station (BS), if the decoded message corresponds to a packet that was not transmitted the maximum number of times. When the MS receives the ACK, it adjusts its data rate in accordance with a bit (bits) speed control, transmitted from the BS, which confirms the transfer. Bits control the speed adopted by the mobile station from the base stations, which did not pass the ACK will be ignored. The mobile station monitors the bit rate control from all base stations only when the previous transmission corresponds to the package that was handed to the maximum allowed number of times.

This approach has several advantages. One of them is that the previous transmission is not the last packet transmission, the base station may decide the data rate for the next transmission only if it confirms the previous transmission of the ACK message and waits for a new transmission. In addition, when the base station does not confirm previous transmission from the mobile station an ACK message, it may not transfer any of the control commands data rate that provides, therefore, efficient use of power and confidence that the bits of the speed control will be ignored and will not be interpretive the change as a team HOLD mobile station. Another advantage is that with this technology, both in the primary and non-primary base stations is the same interaction. Therefore, even when the primary base station is changed when switching between cells, there is no impact on the operation of the speed control from base stations during soft transfer service.

When using this technique may be a problem if there are unbalanced load between base stations involved in the transfer. For example, the problem may occur if, for example, MS 202 performs a soft transfer from the primary station BS 204 to the non-primary BS 206 and the primary BS 204 a fully loaded on a reverse link excess over thermal (ROT) 7 dB, while the non-primary BS 206 has relatively little loaded reverse communication channel, such as ROT 2 dB. In this example, the unbalanced load MS 202 may have the best reverse communication channel with a non-primary BS 204, since the signal transmission from the MS 202 impact is less mutual interference. On the other hand, the reverse communication channel with the primary BS 204 may be weak, even though the primary BS 204 may have a better direct communication channel c MS 202. In this scenario, the non-primary BS 206 may decode the data packet to the MS 202 and the PE idawati the acknowledgement message ACK to the MS 202. As a non-primary BS 206 little loaded, she can transfer in MS bits (bits) speed control data to increase the data transfer rate. The primary BS 204, on the other hand, can be fully loaded or overloaded, and if she receives the transmission from the MS 202 with a small value of the signal/noise ratio, it may not be able to decode the transmission and to transmit acks. If the primary BS 204 does not decode the transmission from the MS 202, it does not send the control command data rate in MS 202, losing, thus, control of the transmission of MS 202, even though it takes more interference from the MS 202. If MS 202 adjusts its data rate in accordance with a bit (bits) speed control passed region BS 206, and increases the speed of data transfer, this can lead to an overload of the primary BS 204, which receives more interference from MS 202, over which she has no opportunity to exercise adequate control. One solution to this problem is to BS 204 was decoding the packets transmitted in MS 202 via a reverse control channel packet data (R-PDCCH), and checked the data rate. If the data rate of the MS 202 is higher than the required primary BS 204, BS 204 may control the data rate of the MS 202, transmitting the request to a non-primary BS 206 is pravity in MS bits (bits) RC (CA, speed control) to reduce the data rate MS. The primary BS can transmit the request to a non-primary BS directly or via the system infrastructure or data channel of direct communication between base stations, or by using other methods, as appropriate for your system configuration.

Another problem when using this technique (transmission confirmation ACK from BS to MS) is that as the primary BS 204, and a non-primary BS 206 should be aware QoS requirements to the mobile station. In most scenarios, a non-primary BS 206, which decodes the transmission MS only in rare cases, does not have accurate information about QoS and current requirements of the MS 202. In the absence of QoS requirements MS 202 non-primary BS 206 will not be able to send the appropriate command to control the rate of data transfer in MS, while the primary and non-primary BS does not endorse this information through the channel of direct communication between base stations for sharing this information.

Case II

In the second embodiment, the MS 202 adjusts its data rate in accordance with a bit (bits) RC only from the primary BS 204. In other words, the MS 202 adjusts its data rate in accordance with a bit (bits) speed control passed BS 204, which is currently designated as Pervin what I BS, even if the acks will be made from a non-primary BS 206. This technique has the advantage consisting in the fact that if the primary BS is not required to change the data rate, it will not transmit bits (bits) speed control that MS believes HOLD (hold), and saves energy in the forward link (FL, SC) BS. Thus, even if a non-primary BS 206 transmits acks in MS, a non-primary BS 206 does not transmit bits (bits) speed control in MS. If the primary BS 204 is overloaded, it can transmit bits (bits) speed control DOWN (reduce), and MS adjusts its data rate accordingly, even if a non-primary BS transmits acks. In accordance with this embodiment, only the primary BS 204 should contain information about QoS and update the current requirements for the mobile station.

The problem with this technique is that a non-primary BS 206 does not have the capacity management, which she takes when sending MS and which acts as a hindrance in receiving other MS. In the case of unbalanced transmission loss between the direct channel and the reverse channel of communication non-primary BS receives unregulated power from MS. In accordance with the embodiment, this problem can be solved only when there is Ervina BS 206 queries the primary BS 204 to transmit the control command speed DOWN. Non-primary BS can transmit the request to the primary BS directly, or through the infrastructure of the communication system or a channel of direct communication between base stations, or by using other methods, as appropriate for your system configuration.

This approach to rate control algorithm to control the rate of data transmission is not fully defined in the mobile communication environment, when MS 202 performs the function of switching between cells. Before switching between cells BS 204 is a primary BS, while the BS 206 is a non-primary BS. Due to the movement of the mobile service, the received signal is a non-primary BS 206 may be stronger than the signal of the primary BS 204. Therefore, during switching between cells MS 202 transmits the frames to the switch indicating 206, as its new primary BS. Before switching frames will be decoded by the base station, BS 204 considers itself to be the primary BS to MS 202. The problem occurs because the MS 202 does not know when to start counting BS 206 his new primary BS and begin to see bits of the RS from the BS 206. This problem can be solved, when the MS 202 accepts commands to control the speed of both, primary and non-primary BS during the switching between cells and uses the rule OR-of-HOLD (OR HOLD), according to which the MS will keep her with the speed of data transmission, if any of the BS transmits a command to the HOLD, and then use a rule OR-of-DOWN (OR REDUCE)when the MS decreases its data rate, if any of the BS transmits a command to decrease the transmission speed. This approach provides for two BS of greater transmission control MS 202. In yet another embodiment, which solved this problem, MS 202 receives the control command speed data only from the previous primary BS 204 during the switching period. Only when the last indicator switch will be transmitted or MS 202 receives confirmation on the switch, it begins to perceive the control command speed from the BS 206, the new primary BS. BS 206 begins to transmit the control command speed when it decodes the indicator switch. During the period from the moment when the indicator switch is decoded BS, until the MS receives the confirmation, MS 202 accepts bits (bits) speed control from the BS 204, while the BS 206 transmits bits (bits) speed control. Since in the absence of transfer speed control in forward channel speed control (F-RCCH) of the BS 204 will be interpreted MS 202 as the message HOLD, none of the base stations will not be able to change the data rate of the MS 202 during this interim period.

Case III

When using this technique all sectors of cells in the active set of the MS involved in the management of the data rate MS. This control is symmetric with active members of the set MS, managers increase the speed of the MS with the application of a rule OR-of-DOWN, followed by a rule OR-of-HOLD. This technique has the advantage consisting in the fact that all the BS communicates with the MS, will participate in the management of the data transmission rate when transmitting MS and, thus, any individual MS have less of an impact on ROT base station, and provides more control. This method works in a similar way as when soft transfer service, and when switching between cells.

However, when using this technique, many problems arise, in particular, in scenarios where the set of base stations during a soft handover service is not located close to each other, and decisions by decoding each of them not known to other base stations in the point in time when each of the BS makes its decision on management of data transfer rate. For example, in a system with a hybrid automatic request for retransmission of the data (HARQ) MS does not transmit a new packet until then, until it reaches the acks from one of the base stations during a soft handover area is uzywane, or up until the MS sends a packet the maximum number of times. Therefore, when the previous transmission is not the last packet transmission, the base station does not know whether it is to plan for MS new transmission until then, until it decodes the previous transfer and does not transmit the acknowledgement ACK to the mobile station. In the absence of this information, the BS, which transmits the confirmation of the previous transmission in the mobile station may transmit the command HOLD for energy savings in direct communication channel. However, in accordance with rule'OR-of-HOLD MS will not be able to increase its data transmission rate up until it does not receive acks from all base stations simultaneously. To solve this problem, a base station that is not transmitting MS acks should all the time to transmit the control command speed UP (boost). This includes times when the MS does not transmit its reverse packet data channel, because the base station may not be able to distinguish the absence of transmission from redaktirovaniya transmission. This approach is extremely not efficient use of energy, since each BS wasted spend energy on direct communication channel with a constant transmission of control commands speed UP, until the base station is not before the article in the mobile station acks.

Case IV

In this embodiment, all sectors of a cell in the active set of MS control to increase the transmission rate of the MS using rules OR-of-DOWN, followed by a rule OR-of-HOLD as in the case of III. However, unlike the Case of the third control is asymmetrical, because the primary BS provides the fundamental regulation by increasing the data rate of the MS, while the non-primary BS provide control overload. In other words, the primary sector passes in MS command speed control with three States (-1, 0, +1) based on the required QoS, where the lack of transfer (0) bit rate control in the control channel rate corresponds to the HOLD. Non-primary BS transmits bit speed control ON-OFF (-1, 0), where the lack of transfer (0) corresponds to team UP or has no value, while the ON state corresponds to the command DOWN. Non-primary BS may transmit the control command speed based on the overload level of the corresponding non-primary BS. Non-primary BS transmits to the MS management team speed UP, if a non-primary BS is not overloaded, and the command speed control DOWN, if a non-primary BS is overloaded. For example, a non-primary BS may transmit the control command speed UP, if it ROT indicates a low level of congestion, and the team management is possible speed DOWN, if it ROT indicates a high level of congestion. In this embodiment, the bit rate control from the BS 206 may be common to all mobile stations 202, for which BS 206 is not primary.

It should be noted that the approach described above allows you to spend a very small amount of energy is the direct channel non-primary base stations, because the team UP corresponds to no transmission bit rate control. The team is DOWN from a non-primary BS may be transferred only if the system is heavily overloaded, providing, thus, a control for a non-primary base stations that are listed as a disadvantage for the case II. For example, if it is determined that the ROT in the sector exceeds a specified amount, for example, 7 or 8 dB, then a non-primary BS is overloaded, and it transmits the command -1 speed control that is a control command speed DOWN. Otherwise, a non-primary BS is neprikrashennaya and transmit the control command speed equal to 0, which represents the team UP. Because it is less likely that the system will be overloaded for a long period of time, the command passed DOWN infrequently. For most of the time in this embodiment is not overloaded BS will transmit the speed command data representing the Wallpaper 0, which corresponds to the absence of a transfer command. Because neprikrashennaya BS does not transmit a command to control the speed by this method, therefore, will not be consumed too much energy from a non-primary sector.

Because this approach is asymmetric, the control speed at the soft transfer service must be specified, as when switching between cells in case II. During the switching between cells, you can use a more conservative approach. In the embodiment, the MS decodes bits (bits) speed control data from the primary BS 204 (base station, the service area where the MS leaves)and non-primary BS 206 (base station in the service area of which includes MS), as the size of the three States -1, 0, or 1, representing DOWN, HOLD UP, respectively. The switching operation between the cells begins when the MS transmits a signal CELL_SWITCH_INDICATOR (indicator switch between cells), which denotes the BS 206, as its new primary BS. During the period from the beginning of the switchover operation until, when MS will not accept END_SWITCH_INDICATOR (indicator end switch) (confirmation from the base station indicating that the switching operation has been completed, or will not be transferred indicators NUM_SOFT_SWITCHING_FRAMES (number of frames soft switch), MS IP which leverages your same logic for interpreting bits (bits) speed control from both stations BS BS 204 and 206. During this period, the MS applies the rule OR-of-HOLD, followed by a rule OR-of-DOWN command speed control from BS BS 204 and 206. During the switching period, the MS 202 is not able to increase the speed, even if the new primary BS 206 transmits the command UP in accordance with rule'OR-of-HOLD. Thus, this approach is conservative during the switching period.

In yet another embodiment, during the switching period MS 202 interprets the control command speed from the BS 204 as a team with three States (-1, 0, 1), while it interprets the control command speed from the BS 206 as a team ON-OFF (-1, 0) (enable-disable). After MS 202 will END_SWICH_INDICATOR, which means BS 206, as its new primary BS, or give NUM_SOFT_SWITCHING_FRAMES, which indicate the switch, the MS starts to interpret the control command speed from the BS 204 as ON-OFF and speed control from the BS 206 as teams with three States. This approach is more aggressive than previously described technology, as it allows BS 204 to increase the data rate of the MS 202 until then, until it decodes CELL_SWITCH_INDICATOR. During the period, while performing a decoding CELL_SWITCH_INDICATOR using BS, until the time when MS will END_SWITCH_INDICATOR, MS 202 may not increase the transmission speed of the data is, even if the new primary BS 206 transmits the command UP, since the control command speed from the previous primary BS 204 is interpreted as MS team HOLD.

Methods of combining multiple indicators speed control

Generalized method of combining multiple indicators speed control includes the application of weighting factors to the different adopted commands speed control. For example, the primary base station may be assigned a greater weighting factor than a non-primary base station in the active set of MS. Indicators commands weighted velocity can then be combined to obtain the total speed command, which is used to control the rate of data transfer from MS. As described above, the Case III corresponds to the case when equal weights are used for control commands speed received from all base stations of the active set of mobile stations. Case IV is a special case of weighting applied to the control commands speed, where a weight of 0 is used for command HOLD from a non-primary BS. Various special cases of the technology weighting for interpreting and combining indicators control the data rate of the MS received from members of its active set, isany below.

Rules of combination control data rate for General/under speed control

If the MS receives the acknowledgment message ACK or after its last subpackage, MS decodes indicators speed control of all F-RCCH, which were assigned to the MS members of the active set of MS. Each indicator speed control has three States: DOWN, and HOLD UP. The effect of the command speed is to change the authorized T/P (T/P, the ratio of traffic to a pilot signal) by a certain amount, where authorized T/P is a maximum value of the ratio of traffic to pilot-signal"allowed for the mobile station in the transmission, and is used as an indicator of the speed of data transmission of the MS that it can support. In one embodiment, the MS combines all indicators speed control, which she accepts on the basis of the following rules OR-of-DOWN:

If any indicator is DOWN, then MS reduces its authorized ratio T/P by a certain amount from the current level.

If there is no DOWN indicator and at least one indicator is a HOLD, then the MS maintains the current authorized level of attitude T/p

Otherwise, all the indicators are UP, and MS increases their authorised by the ratio T/P by a specified amount from the current level.

It was noted that the specified amount by which the MS increases or decreases its current authorized the ratio T/P may be the same or may be different depending on the current authorized relationship T/MS P.

Rules of combination speed control for special speed control

For special speed control, if the MS receives from the BS acknowledgement ACK channel (F-ACKCH, it decodes all F-RCCH, which is assigned to the MS, regardless of whether the MS acknowledgement ACK from the BS or not. The reliability of the communication system, which uses this procedure of reception can be improved by using the following weighting methods.

Indicator speed control from the primary BS has three States: RATE_DECREASE, RATE_HOLD and RATE_INCREASE (to reduce speed, to keep the speed and increase speed).

Indicator speed control from a non-primary BS has two States: RATE_DECREASE and RATE_HOLD. This can be interpreted as a method of weight coefficients when the status indicator speed control RATE_HOLD and RATE_INCREASE from a non-primary BS assigns a weighting factor of ZERO.

MS combines the required indicators speed control based on the following rules:

If any indicator is a RATE_DECREASE, then MS reduces their speed to the required value, for example, n is the unit.

If none of the indicators is not RATE_DECREASE and at least one indicator is a RATE_HOLD, then the MS maintains the current state.

If none of the indicators is not RATE_DECREASE or RATE_HOLD and at least one indicator is a RATE_INCREASE, then the MS increases its speed to the required value, for example by one.

Otherwise, all the indicators speed control are RATE_HOLD and MS maintains the current data rate.

It should be noted that MS combines the required indicators speed control, which may include indicators speed control all members of the active set of MS or to include indicators speed control only some members of the active set of MS.

The procedure is performed while switching between cells for a special speed control:

After the MS initiates the switching operation between the cells, sending CELL_SWITCH_INDICATOR, MS assumes that each indicator speed control as from the old primary BS and the new primary BS has three States: RATE_DECREASE, RATE_HOLD and RATE_INCREASE. Indicators speed control from all other non-primary BS remain unchanged and have two States: RATE_DECREASE and NULL_INDICATION. Indicators speed control combined with the use of the ex the same rules of combination, which were described above.

After taking END_SWITCH_INDICATOR or after the transfer NUM_SOFT_SWITCHING_FRAMES MS assumes that the indicator speed control from the new primary BS has three States: RATE_DECREASE, RATE_HOLD and RATE_INCREASE. Indicators speed control from all other non-primary BS, including the old primary BS, have two States: RATE_DECREASE and NULL_INDICATION. Indicators speed control are combined on the basis of the same rules of combination, which have been described above.

An alternative approach consists in the definition of States F-RCCH from a non-primary BS, "in process"on the basis of what is accepted by the appropriate F-ACKCH from the associated BS. For this approach, the following procedure is used.

If acks are taking from the F-ACKCH, then the MS interprets that the corresponding F-RCCH the same non-primary BS has three States: RATE_DECREASE, RATE_HOLD and RATE_INCREASE.

If acks was not taken from the F-ACKCH (after the last subpackage), then the MS interprets that the corresponding F-RCCH the same non-primary BS has two States: RATE_DECREASE and NULL_INIDICATION.

All other rules of combination remain the same as described above.

Figure 3 shows the precedence diagram illustrating a method of combining indicators speed control for shared/group speed control. In a common/collective control the speed transmit a single command speed control, which track all mobile stations or mobile stations in the service area of a base station. The sequence of operations begins in block 302. In block 304, the MS decodes the indicators speed control received from members of the active set of the MS to the BS. In block 306, the MS determines whether one of the indicators speed control AUTHORIZED_T2P_DECREASE (command speed control DOWN). If at least one of the indicators is a AUTHORIZED_T2P_DECREASE get the output "YES", then the sequence continues at block 308. In block 308 MS reduces its authorized level of T/P (traffic-to-pilot signal) by a specified amount. The sequence then continues in block 310, where the process of combining ends.

Returning to block 306, if none of the indicators is not AUTHORIZED_T2P_DECREASE, i.e. the "NO", then the sequence continues at block 312. In block 312, the MS determines whether one of the indicators speed control AUTHORIZED_T2P_HOLD (command speed control HOLD). If at least one of the indicators is a AUTHORIZED_T2P_HOLD, the result is "YES", then the sequence continues at block 314. In block 314, the MS maintains its current authorized level of T/P. the Sequence of operations then continue what is in block 310, where the process ends.

Returning to block 312, if none of the indicators is not AUTHORIZED_T2P_HOLD, the result is "NO", then all indicators should be AUTHORIZED_T2P_INCREASE (management team speed UP, because the indicators can represent only one of three values AUTHORIZED_T2P_DECREASE, AUTHORIZED_T2P_HOLD or AUTHORIZED_T2P_INCREASE. Therefore, in block 312, if none of the indicators is not AUTHORIZED_T2P_HOLD, the sequence of operations continues at block 316. In block 316 MS increases its authorized ratio T/P by a specified amount. The sequence then continues in block 310, where the process ends.

Figure 4 shows the precedence diagram illustrating a method of combining speed control approach with a special speed control. In approach, with a special speed control separate command speed control, specific to each mobile station, transmit to all MS. The sequence of operations begins in block 402. In block 404, the MS decodes the indicators speed control received from the primary and non-primary BS. Indicator speed control from the primary BS can be a RATE_DECREASE, RATE_HOLD or RATE_INCREASE. Indicator speed control from a non-primary BS can be RATE_DECREASE or NULL_INDICATION. The sequence continues to block 406 At block 406, the MS determines whether one indicator of the speed control RATE_DECREASE. If at least one of the indicators is a RATE_DECREASE, the "YES" comes from block 406, then the sequence continues at block 408. In block 408, the MS decreases its data rate. For example, the MS may reduce the data rate by an amount equal to one. The sequence of processing then continues to block 410 where the process of combining ends.

Returning to block 406, if none of the indicators is not RATE_DECREASE, the "NO" comes from block 406, then the sequence continues to block 412. In block 412, the MS determines whether the indicator speed control from the primary BS RATE_HOLD. If at least one of the indicators is a RATE_HOLD, then the sequence continues to block 414. In block 414 MS maintains its current data transmission rate. The sequence then continues to block 410 where the process ends.

Returning to block 412, if none of the indicators is not RATE_HOLD displays the result "NO", then the sequence continues to block 416. In block 416, since none of the indicators is not a RATE_DECREASE and the indicator from the primary BS is not RATE_HOLD, MS increases its soon the be data. The sequence then continues to block 410 where the process ends.
