The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates, in General, to a cellular data networks and, in particular, the present invention relates to a method and device to provide the maximum bandwidth of the data channel during the implementation of Pereybere between adjacent cells of the cellular network data.

The LEVEL of TECHNOLOGY

Technology General packet radio services (GPRS) and enhanced data for global evolution (EDGE), global system for mobile communication (GSM) are designed to enable the service subscriber to send and receive data through the packet without using network resources in the mode switching channels. The packet radio services GPRS, EDGE and 3rd generation (3G) enable effective use of radio and network resources when data transmission characteristics are (i) based on the package, (ii) intermittent and non-periodic, (iii) may often transmitted with a small amount of data transmission, for example, less than 500 octets, or (iv) may not frequently transmitted, with a large amount of data, for example, more than a few hundred kilobytes. User application programs may include an Internet browser is, e-mail etc.

Figure 1 - structural diagram of a typical cellular communication system, which is designed for use in explaining operation of the present invention. As shown in figure 1, the cellular communication system 100 includes multiple cells 102-116, each of which defines the area of software radio (coverage), which is a fixed base station in each cell. For example, as shown in figure 1, the cell 102 determines the area of software radio, which is set by the base station 118, which is located in the cell 102, and similarly each of the remaining cells 104-116 defines the related area providing radio communication, which is set corresponding base station (not shown)located in each cell 104-116.

When the mobile station such as a cellular phone for, moves together with the user from position x to position y in the cellular communication system 100, the mobile station continuously monitors the signal from base stations of cells 102-116 and, based on some selection criteria, selects the cell for transmission and reception of data packet with the network 120 via an associated base station. For example, when the mobile station is located in the cell 114, if the characteristics of the signal from the cell 114 awsumsauce, that, based on the selection criteria, the cell 114 is selected as having the "best" area to provide radio communication, the cell 114 is considered a "serving cell or cell from which the mobile station which receives and transmits packet data.

The mobile station continues to monitor the characteristics of the signal from cell 102-116, and, as shown in figure 1, when the mobile station sequentially moves along the marked path from position x to position y, the mobile station moves from the area of provision of telecommunication-related cell 114 in the area of providing radio communications associated with other cells, such as cells 116 and 106. As soon as the signal from another cell, for example cell 116, will be such that the cell 116 will be considered as the best cell, the mobile station will Pereybere cell 116 as a serving cell, as long as the characteristics of the signal from another cell, for example cell 106, will not be such that the cell 106 will be considered as the best cell, and the mobile station will Pereybere cell 106 as a serving cell, etc.

As a user of the mobile station is able to cross the area of providing radio communications associated with more than one of the cells 102-116 known mechanism to ensure sequence integrity specified in the current GSM specifications GSM 04.60, "the System is a digital cellular (phase 2+); technology General packet radio services (PERSON GPRS); interface mobile station (PS, MS) - base station (SBS, BSS); control Protocol wireless link/control access to the transmission medium (RLC/MAC)" (European Institute of standardization in the field of communications (EISS, ETSI), European standard (series of telecommunications) ("Digital cellular telecommunications system (Phase 2+); General Packet Radio Service (GPRS); Mobile Station (MS) - Base Station System (BSS) interface; Radio Link Control/Medium Access Control (RLC/MAC) protocol", (European Telecommunications Series)), embedded in services when transmitting packet data to ensure sequence integrity of the data stream, when the mobile station leaves the area of software radio one cell and enters a new cell.

Figure 2 - schematic diagram of a partial view projection data for GPRS/EDGE technologies. As shown in figure 2, and the mobile station 200, and the network 202 includes equivalent related in hierarchical levels, such as level 204 control logical connection (LLC), level 206 of the radio line control (RLC), 208 control access to the transmission medium (MAC) and physical layer 210. Packet data that is transmitted between the mobile station 200 and the network 202, are formed at the level of 204 control logical connection to send in personnel management logical connection, each frame of the control logic is Kim compound changes in the amount of up to 1530 octets. When one frame control logical connection logically pushed down by the projection data, it is divided into many blocks of data management wireless link, each data block management wireless link contains 22-54 octets. Each block of data management wireless link, in turn, is divided into four pulse packet physical layer with added redundancy.

As shown in figures 1 and 2, if the mobile station 202 is in location x and sends the data over GPRS/EDGE network 202 via the serving cell, i.e. the cell 114, the cell 114 receives and acknowledges receipt of all data blocks of the management of the wireless link contained in personnel management logical connection corresponding to the data GPRS/EDGE technologies, transmitted to the network 202. If, at the time when the serving cell 114 receives the control frame to a logical connection from a mobile station 202, the mobile station 202 performs previsor new serving cell, such as a serving cell 116, the mobile station 202 Pereybere cell 116, completing the current time stream blocks to the cell 114 and re-setting the time stream blocks to the cell 116, which now becomes the serving cell.

According to well-known mechanism to verify sequence integrity as the only time a thread blocks in the charity and love, set to a new serving cell 116, the mobile station 200 reorganizes its window transfer blocks of data management wireless link and starts sending the first data block management wireless link in the last unconfirmed control frame to a logical connection. As a result, all control blocks radio line corresponding to the last transmitted control frame to a logical connection at that time, when the cell 114 has been serving cell, has to be transmitted again, despite the fact that some of these control blocks wireless link may have been correctly accepted by the servicing cell 114. For example, if 53 of the control unit of the wireless link were necessary in order to transmit only the control frame to the logical connection, and blocks 1-50 control wireless link were successfully transferred prior to the time in which it was executed previsor, units 1-50 control wireless link will be discarded and therefore need to be re-transferred to the new selected cell in order to continue the transmission of the control frame to a logical connection.

Thus, in the environment in which the probability of rapid Pereybere cell is high, such as overpopulated urban environment, a well-known mechanism to verify sequence integrity creates an unfavorable reduction in bandwidth transmission of the data due to periodic drop duly adopted at every Pereybere new serving cell.

Accordingly an improved method and apparatus for reducing the impact of Pereybere cell on the data rate of the user.

A DETAILED DESCRIPTION of the PREFERRED OPTION IMPLEMENTATION

The present invention provides a method and apparatus for reducing the influence of Pereybere cell throughput of the data channel of the user. As soon as another cell in relation to the currently selected cell or serving cell becomes a candidate for previsor, waiting tone Pereybere is transmitted from the physical layer to the adjustment module, which then stores the size of the current frame control logical connection in memory. An adjustment module transmits the specified frame size control logical connection to the control level logical connection for the packet data transfer was performed using the specified frame size control logical connection. Packet data is then transferred, using the specified frame size control logical connection before making the adjustment module signal the end of Pereybere, indicating that previsor another cell is completed, or acceptance module regulirovaniya emergency stop Pereybere, indicates that previsor another cell was aborted. When the signal is received the end of Pereybere, packet data are transferred to another cell using a previously saved frame size control logical connection. When adopted, the signal abort Pereybere, when transmitting packet data of the current selected cell continue to use the saved frame size control logical connection. As a result, using a dynamic adjustment of the frame size control logical circuits within the data session before previsora another cell the present invention reduces the impact of Pereybere cell on the data rate of the user.

Figure 3 - block diagram of the device for maximum throughput of the data channel during the implementation of Pereybere cell in the communication system according to the present invention. As shown in figure 3, the communication system according to the present invention includes a mobile station 300, such as a telephone for cellular communication device pager (search call), personal digital assistant (PDA) or similar wireless device that sends data to the network 302 and receives data from it. The mobile station 300 and the network 302 includes equivalent unit 30 control logical connection, along with the level 305 controls with equivalent related in hierarchical levels, such as level 306 control logical connection (LLC), 308 control wireless link (RLC), 310 control access to the transmission medium (MAC) and physical layer 312. Block 304 control the logical connection includes a matching module 324 adjustment for regulating the length of the control frame to the logical connection, along with the corresponding memory 328, which are described in detail below.

Packet data that is passed between the mobile station 300 and the network 302 via the serving cell, are formed at the level 306 control logical connection to send in personnel management logical connection, each control frame to a logical connection changes in the amount of up to 1530 octets. When the control frame logical connection logically pushed down by the projection of the data frame management logical connection is divided into many blocks of data management wireless link, each data block management wireless link has a length 22-54 octet. Each block of data management wireless link, in turn, is divided into four pulse packet physical layer with added redundancy. Level 308 management of the wireless link, first of all, uchastie the correction of errors in the radio level, to resolve intermittent errors that are the result of the fading channel, in addition to handling certain aspects of Assembly and disassembly of the transmission of data via GPRS/EDGE.

In addition, data frames GPRS/EDGE directed from level 308 controls the wireless link to the appropriate level 310 control access to the transmission medium (MAC), which organizes the transmission and reception of information on the basis of the packet on the physical layer 312 and appropriate, and the physical layer primarily comprises logic with which the mobile station 300 is informed of their right to transmit in a given time. Level 310 control access to the transmission medium is also responsible for the recognition of messages addressed to the mobile station 300 on the downlink. Finally, the physical layer 312 provides an interface between the radio hardware and the processor call processing (not shown), which includes the planning of transmission and reception of a physical boost control receiver, power control of the transmitter, level measurement signal, etc.

4 is a diagram of information flows data channel during Pereybere cell in the communication system according to the present invention. Although figure 4 illustrates the data flow using the procedure and apparatus of the present invention, when the mobile station 300 sends data to the network 302, it should be understood that, as described above, the network 302 includes a hierarchical equivalents for each level 306-312 mobile station 300, respectively along with the equivalent block 304 control logical connection, so that the method and apparatus of the present invention is equivalent to the case when the network 302 sends data of the mobile station 300. As a result, a separate description of the data from the network 302 to the mobile station 300 is omitted merely for the sake of brevity. However, during transmission on the downlink from the network 302 to the mobile station 300 in the environment with re-election, managed network, the network 302 determines when the mobile station 300 will be previsor another cell using measurement information of energy sent from the mobile station 300, in order to determine which cell the mobile station 300 will Pereybere and when this pervisor will happen. This information is an energy measurement is then taken into account by the signal waiting Pereybere and signal abort Pereybere, which will be described below.

As shown in figures 1, 3 and 4, when the cell 114 is selected by the mobile station 300 as a serving cell, the mobile station 300 sends packet data to the network 302 through the cell 114, while at the same time, the concentration in the second station 300 continues to monitor the characteristics of the signal from cell 102-116. Packet data sent by the mobile station 300, are formed at the level of 304 controls the logical connection of the mobile station 300 to transmit the cell 114 in personnel management logical connection, each control frame to a logical connection changes in the amount of up to 1530 octets. When the control frame logical connection logically pushed down by the projection data, it is divided into level 308 control wireless link to multiple data management wireless link, each data block management wireless link has a length 22-54 octet. Each block of data management wireless link, in turn, is divided into four pulse packet physical layer at the physical layer 312 with added redundancy.

Although the frame length control logical connection is changed, if the control frame to the logical connection is had, for example, a length of 1000 octets would be a 53 block management data wireless link in order to send the control frame to a logical connection diagram of channel coding CS-1. Assuming that all periods of time units in the time interval physical channel corresponding to the physical layer 312, which are intended for data transmission, are planned, the mobile station 300 in this case transmits the control frame to the logical connection is cake 114 53 controls the wireless link, moreover, the cell 114 sends a confirmation message of the mobile station 300 each time after the cell 114 receives four control block radio line corresponding to the four burst physical level.

In particular, as shown in figure 4, when packet data is transmitted from the mobile station 300 selected cell 114 in the frame x control logical connection, and the frame x control logical connection has, for example, a length of 1000 octets, the mobile station 300 starts the transmission of the cell 114 blocks 1-4 control the wireless link connected with the frame x control logical connection. Once the blocks 1-4 control radio line taken in the cell 114, the cell 114 400 transmits a message confirming mobile station 300, which confirms the reception of blocks 1-4 control the wireless link. Upon receipt of a message 400 confirm the mobile station 300 transmits the following part of the frame x control logical connection in blocks 5-8 control the wireless link, which is then confirmed, when taken by cell 114, and so the Process continues until the last block of management of wireless link, i.e. to the control unit by wireless link <last>, which is associated with the sent frame x control logical connection, and to confirm the cell 114 receive all fifty-three control blocks wireless link which support the ima for the frame transmission x control logical connection.

As soon as the transfer frame x control logical connection is completed, the mobile station 300 transmits the next frame x+1 control logical connection if it is available for communication using the number of control blocks of the wireless link, which is necessary, which, of course, again depends on the length of frame x+1 control logical connection. When the transmission of the next frame x+1 control logical connection of the mobile station 300 starts, passing blocks 1-4 control the wireless link associated with the frame x+1 control logical connection, cell 114, and the cell 114 acknowledges receipt each time after four control unit wireless link taken, as described above, until, until sent to the last control unit wireless link <last>corresponding to the frame x+1 control logical connection. As soon as the transfer frame x+1 control logical connection is completed, the mobile station 300 transmits the next frame x+2 control logical connection, if the next frame is available for transmission, and cell 114 confirms the reception after four control unit wireless link taken, etc. as a result, the data transfer process continues until the transfer packet data, the mobile station 300 will not be or is terminated, or interrupted, or emergency exit is Jena. As soon as the transfer packet data or completed, or interrupted or aborted, the process of Pereybere ends.

At some point in the process this packet data mobile station 300 begins to discover that another cell, for example cell 116, is a candidate for previsor as serving cell. This detection can occur at any time during the packet data, for example, as shown in figure 4, at time t1that is the time to send the last control unit wireless link <last>corresponding to the frame x control logical connection. As a means to minimize unnecessary re-election, the current GSM specification GSM 05.08, "digital cellular (phase 2+); management subsystem radio communication lines" (European Institute of standardization in the field of communications (EISS), European standard (series of telecommunications) ("Digital cellular telecommunications system (Phase 2+); Radio Subsystem Link Control" (European Telecommunications Standards Institute (ETSI), European Standard (Telecommunications Series)), requires that adjacent cell had the best signal quality over a period of at least five seconds to Pereybere this cell. The present invention uses this five-second interval before Pereybere as input logical information for the dynamic is about to change frame size control logical connection during the data session, using the method and apparatus of the present invention. As a result, by dynamically changing the frame size control logical connection during the data transfer, the present invention provides a maximum bandwidth of data transfer.

In particular, as shown in figure 3 and 4, according to the present invention, once the mobile station 300 at time t1detects that the cell 116 is a candidate for previsor, the physical layer 312 report block 304 control logical connection, sending a signal 402 wait Pereybere module 324 adjustment. According to the present invention, the timing to send the signal 402 wait Pereybere coincides with the beginning of the five-second interval, i.e. time t1. After receiving signal 402 wait Pereybere level 306 control logical connection transmits a signal 332 of the current frame size control logical connection, reporting module 324 adjust the frame size control logical connection, which is not yet fully transferred, which in the example shown in figure 4, is the frame size x control logical connection. Module 324 adjustment then stores the frame size x control logical connection as the current size of the CR is and control the logical connection in the memory 328. Module 324 adjustment then sets the frame length control logical connection at a specified minimum value, which according to a preferred variant implementation of the present invention is 100 octets, sending a signal 334 a given threshold level 306 controls the logical connection. Although the present invention uses 100 octets as the set value for the length of the control frame to the logical connection, it should be understood that the present invention is not limited to the use of 100 octets as defined length of the control frame to a logical connection and that the present invention is intended to include the use of other values for the length of the control frame to a logical connection.

Thus, according to the present invention the mobile station 300 operates in a state with a normal size frame, while the frame length control logical connection is not established within a specified minimum level 306 controls the logical connection. However, as soon as the frame length control logical connection is established at a specified minimum value, the mobile station 300 moves from a state with a normal frame size in the state with the minimum frame size.

When the mobile station 300 is in the able with a minimum frame size, the next frame x+1 control logical connection in this case is transmitted from the mobile station 300 to the cell 114, as described above, using the specified minimum length of the control frame to a logical connection and a corresponding number of control blocks wireless link. The number of control blocks wireless link depends on the used coding scheme to the channel, and is equal to the amount of useful information (LLC)/(the amount of useful information data block RLC) + remainder (the amount of useful information (LLC)) module (the amount of useful information data block RLC). Therefore, when the frame length control logical connection 100 octets the number of control blocks wireless link required for the coding scheme CS-1, will be equal to six blocks of data management wireless link. As a result, the number of control blocks of the wireless link, the required data will be potentially reduced while in the state with the minimum frame size from 53 controls the wireless link up to six control units of the wireless link, taking the length of the frame 100 octets.

Once sent the last control unit wireless link associated with the next frame x+1 control logical connection, the mobile station 300 sends the next frame x+2 control logical connection using the specified minimum frame length control is a logical connection and a corresponding number of control units by a wireless link, moreover, the cell 114 acknowledges receipt of the control blocks wireless link until then, until you sent the last control unit wireless link <last>corresponding to the frame x+2 control logical connection. The mobile station 300 then continues transmitting the next frame x+3 control logical connection using the specified minimum length of the control frame to a logical connection and a corresponding number of control blocks wireless link, and the cell 114 acknowledges receipt of the control units of the wireless link, as described above, until, until you sent the last control unit wireless link <last>corresponding to the frame x+3 control logical connection, and so on.

As shown in figure 3 and 4, at time tselectthe mobile station 300 has completed the current time stream of blocks in the cell 114 and the newly established temporary thread blocks in the cell 116, due to the fact that the mobile station 300 has completed previsor new serving cell, cell 116. As a result, the signal 404 end Pereybere is transmitted from the physical layer module 312 324 adjustment block 304 control logical connection at time tselect.

Because the signal 404 end Pereybere accepted during the transmission of the control frame to a logical connection, such as CR is and x+3 control logical connection, the mobile station 300 complies with the known mechanism of sequence integrity defined in the current GSM specifications GSM 04.60, "digital cellular (phase 2+); technology General packet radio services (OPRP), GPRS); interface mobile station (PS) system base station (SBS); control Protocol wireless link/control access to the transmission medium (RLC/MAC)" (European Institute of standardization in the field of communications (EISS), the European standard series (telecommunications) ("Digital cellular telecommunications system (Phase 2+); General Packet Radio Service (GPRS); Mobile Station (MS) - Base Station System (BSS) interface; Radio Link Control/Medium Access Control (RLC/MAC) protocol" (European Telecommunications Standards Institute (ETSI), European Standard (Telecommunications Series), therefore, only as a temporary thread blocks re-installed in the new serving cell 116, the mobile station 300 reorganizes its transmission window of the data block management wireless link, re-setting the frame size control logical connection in the value previously stored in the memory 328. The mobile station 300 then sends the first control unit by wireless link from the last unacknowledged frame control logical connection, i.e. frame x+3 control logical connection using pre-stored frame size control logical connection.

As a result, as shown in figure 4, the mobile station is 300 I will send the last unacknowledged frame x+3 control logical connection cell 116, re-sending all associated control units radio line, starting with the first, using the previously saved frame size control logical connection, ie 1000 octets, and so on, setting the mobile station 300 back in the condition with the normal frame size.

Although previsor, shown in figure 4, occurs after the expiration of the five-second warning, t1+5, it is possible that for some reason, such as loss of signal power, previsor does not occur during the five-second warning, t1+5 with or within a certain period of time after a five second warning, as defined in the system requirements. Therefore, according to the present invention, if previsor not completed within the period of five-second warning, t1+5, or emergency has ended for any other reason, as stated in the system requirements, signal 406 abort Pereybere (figure 3) is transmitted from the physical layer module 312 324 adjustment block 304 control logical connection. After making signal 406 abort Pereybere module 324 adjust the mobile station 300 reorganizes its transmission window of the data block management wireless link, re-setting the frame size control logical connection in mn is an increase, pre-stored in the memory 328, and sends the first control unit of the wireless link in the last unacknowledged frame control logical connection, i.e. the frame x+3 control logical connection using pre-stored frame size control logical connection, and continues to transmit packet data to the last selected cell, i.e. the cell 114.

Although the present invention has been described for the length of the control frame to a logical connection is set equal to 100 octets, it should be understood that according to the present invention can be used in any given size the length of the control frame to a logical connection. For example, there may be used a minimum frame size, which is based on the reasonable assumption concerning the amount of useful information control unit of the wireless link based on the coding scheme in the channel and the values defined on the basis of statistics for packets which are often exchanged, for example, just large enough to accommodate often the transmitted packet control at the transport layer. Alternatively, the length of the control frame to the wireless link can be adjusted to "the largest possible size, based on the estimated time remaining in the current cell, which, in turn, can determine what omashu power signal, for example, the total amount of data remaining for transfer to a temporary stream of blocks, or a combination of these or other factors.

5 and 6 the sequence of operations that illustrate how the dynamic adjustment of the frame size control logical connection according to the present invention. As shown in figure 4 and 5, in a state with a normal frame size, the operation 500, the module 324 adjustment determines whether the passed signal 402 wait Pereybere, operation 502. Once the signal out Pereybere admitted, "Yes" at operation 502, module 324 adjustment saves the current frame size control logical connection in the memory 328, operation 504, and sets the frame size to control a logical connection to the specified value, the operation 506. After completion of the operations 504-506 mobile station 300 moves to a state with a minimum frame size, operation 508.

As shown in figure 4 and 6, in a state with a minimum frame size, operation 510, as soon as accepted one of the signals Pereybere 402-406, operation 512, the module 324 adjustment determines whether it is a signal 402 wait Pereybere, signal 404 end Pereybere or signal 406 abort Pereybere, operation 514. If accepted signal 402 wait Pereybere, the process returns to operation 510 and module 324 regulirovanije signals 402-406 of Pereybere, operation 512. If at operation 514 determined that the adopted signal 402 end Pereybere or signal 406 abort Pereybere, the module 324 adjustment sets the frame size to control a logical connection in a pre-stored value, the operation 516, the mobile station 300 then moves to a state with a normal frame size, operation 518.

7 is a graphical representation of the effect on the actual bandwidth of the data channel user changes the length of the control frame to a logical connection according to the present invention. Shows graphs illustrating the total throughput for personnel management logical connection length 500 and 1500 octets and using and without using the method and device in accordance with the present invention for modeling the cumulative impact on the throughput of the data channel of the user re-election every fifteen seconds. In particular, as shown in Fig.7, the resulting throughput for personnel management logical connection length 500 and 1500 octets without the use of the method and device of the present invention presents graphs A and B, respectively, are initially reduced to values less than 7200 bit/s For comparison, the resulting throughput is sposobnosti in personnel management logical connection length 500 and 1500 octets using the method and device of the present invention presents graphs C and D, accordingly, decreasing to 7350 bits/s

So, as you can see from the simulation of figure 7, using a dynamic adjustment of the frame size control logical connection in the data session within a five second period of warning before previsora the present invention reduces the impact of Pereybere cell on the data rate of the user.
