A message processing method and device

Abstract

The inventive embodiment discloses a device of processing a message, which includes: judging whether current data block is the same as previous data block when the decoding fails; if yes, judging whether the previous data block is decoded successfully; reporting the decoded result when the current data block is decoded successfully. The inventive embodiment utilizes the network side to report a page message, judge and process the page message when the decoding fails, therefore, solving the burst errors caused by transient quality drop of air link as well as transient overdose of regulated frame header deviation of mobile terminals, improving the called completing rate and reducing the probability of occurrence of net losing.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a message processing method and device. Background technique [0002] In order to realize the called function, when the mobile terminal is in an idle state, that is, in a standby state, its main task is to receive a paging message from the network side. For example, in the GSM system, the paging message is sent to the mobile terminal through a paging channel (Paging Channel, PCH). Usually, a paging block consists of four normal bursts (Normal Burst, NB). [0003] In the GSM system, the process of establishing a communication link is shown in Figure 1. First, the network side uses the paging channel to broadcast the paging request (PagingRequest) to the mobile terminal according to the paging group where the mobile terminal is located, and starts timer 1; Send a random access burst (Random Access) on the Random Access Channel (RACH); after the network side receives the random ...

Problems solved by technology

Due to the complex environment of the wireless link, if the quality of the air link drops instantaneously, it will cause the mobile terminal to receive a paging block error; the mobile terminal needs to calibrate the frame header with the network side at any time to ensure that the data is received correctly. Although the mobile terminal obtains the deviation between its own frame header and the position of the network-side frame header according to the demodulation of the received data, and adjusts it in real time, due to the complex network environment and the requirements for achieving accuracy, the instantaneous excessive adjustment of the frame header deviation will still cause Mobile terminal receives paging block error code

[0006] In the process of implementing the present invention, the inventor found that the existing technology has at least the following defects: because the solution of the prior art does not take into account the characteristics of the network-side resend paging message, it cannot resist the instantaneous decline of the air link quality and the adjustment of the mobile terminal. The paging block error caused by the instantaneous excess of the frame header deviation leads to a decrease in the called connection rate of the mobile terminal; at the same time, if the paging block error exceeds 3 consecutive blocks, according to the existing downlink failure (DSC) technology , the protocol stack will release the physical link, and if the network is lost, the MS needs to start searching the network again, which increases the power consumption of the mobile terminal
