Embodiment 1

[0028] The processing flow of an IR memory management method provided by this embodiment is as follows figure 2 As shown, the following processing steps are included:

[0029] Step 21. The MS receives the RLC block whose BSN is X sent by the BSC. The MS allocates IR memory for the RLC block and performs air interface decoding on the RLC block. After the air interface decoding is successful, perform step 29; if the air interface decoding fails After that, go to step 22.

[0030] Step 22, the MS judges whether the BSN of the RLC block whose BSN is X is found in the set storage unit.

[0031] In the embodiment of the present invention, a storage unit is set in the MS, and the BSN of the RLC block that has successfully completed the air interface decoding is stored in the storage unit.

[0032] In practical applications, the above-mentioned storage unit may be a receiving window, and the size of the receiving window corresponds to the maximum number of RLC blocks that the MS ca...

Abstract

The embodiment of the invention provides a memory management method and a memory management device. The method mainly comprises the following steps: receiving an RLC (radio link control) block sent by a network side, allocating memory for the RLC block, performing idle decoding on the RLC block, after the idle decoding fails, judging whether block sequence number information of the RLC block subjected to the idle decoding contains the block sequence number of the RLC block or not, if so, releasing the memory allocated to the RLC block, and otherwise, storing soft value information of the RLC block in the memory allocated to the RLC block. The method and the device of the invention can solve the problem of leakage of the memory of a mobile station caused by uplink interactive time difference, and can improve the service efficiency of the memory of the mobile station.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a memory management method and device. Background technique [0002] IR (Incremental Redundancy, incremental redundancy) is a key feature introduced by the EGPRS (Enhanced GPRS, Enhanced GPRS) system, which can speed up the decoding of RLC (Radio Link Control, radio link control) blocks, effectively reducing network The number of retransmissions increases the data throughput rate, especially when the wireless channel condition is poor. [0003] The basic principle of the above-mentioned IR feature is: for an RLC block, if the receiving end fails to decode, the soft value information of the RLC block will not be discarded, but stored in the IR memory of the receiving end. When the sending end retransmits the RLC block, if the receiving end still fails to decode, the receiving end will combine the two soft value information before decoding, which can greatly improve ...
