Flow control processing method

Abstract

The invention discloses a flow control processing method, which comprises the following steps that: a local radio link protocol (RLP), after a periodic relative timer is due, calls a function interface of a local layer two relay (L2R) to analyze a protocol data unit (PDU) sent by a remote end to obtain an analysis result; the local L2R judges whether the occupied space of a local receiving sharedbuffer area exceeds a preset threshold, and performs the flow control and removes the flow control if the occupied space of the local receiving shared buffer area exceeds the preset threshold; otherwise, the local L2R judges whether a flow control signal from the remote end is received after writing data into the local receiving shared buffer area according to the analysis result, and performs theflow control and removes the flow control if the flow control signal from the remote end is received; otherwise, whether the occupied space of the local receiving shared buffer area exceeds the preset threshold is judged, and the steps of sending the flow control signal and removing the flow control are executed if the occupied space of the local receiving shared buffer exceeds the preset threshold; and otherwise, the data is sent to the remote end. The utilization of the method can improve the flow control performance and reduce the resource consumption of the system.

Description

technical field [0001] The present invention relates to a flow control processing technology, in particular to a flow control processing method. Background technique [0002] Data services in the circuit domain are divided into transparent data services and non-transparent data services. Transparent data services have fixed data transmission rates, fixed transmission delays, and variable data error rates; non-transparent data services have variable data transmission rates. , with enhanced error control mechanism and variable transmission delay. [0003] On the terminal side, the data service in the circuit domain is mainly completed by the terminal adaptation function (TAF, Terminal AdaptorFunction) module, which completes the public land mobile communication network (PLMN, Public Land Mobile-communication Network) network users, public switched telephone network (PSTN, Public Switched Telephone Network (Telephone Network) network users and Integrated Services Digital Netwo...

Problems solved by technology

[0005] In the prior art, in the non-transparent data service in the terminal circuit domain, the sub-modules of TAF, that is, the L2R module and the RLP module reside in the system as separate processes In , the two cooperate with each other to implement the functions of non-transparent data services in an orderly manner. However, since the two reside in the system as separate processes, they will occupy resources at any time, so the system consumes a lot of resources; Moreover, when performing flow control processing, only the interaction between the remote peer-to-peer L2R module, the local L2R module and the local TE flow control signals is considered, so the performance of flow control is relatively low
