Network communication function abnormity processing method, application processor and mobile terminal

Abstract

The invention discloses a network communication function abnormity processing method. The method comprises steps that when an abnormality indication message sent as a memory access error is detected by the Modem is received by the AP, the cause of abnormality of the memory access error is determined; if the frequency of occurrence of the same abnormality cause reaches the preset times within the preset duration, a first protocol stack currently used by the Modem is obtained by the AP; the first protocol stack is closed by the AP, and a second protocol stack other than the first protocol stackis selected from multiple protocol stacks supported by the modem; the second protocol stack is started by the AP, and the second protocol stack is made for network registration; if network registration is successful, the current position information is recorded by the AP; if network registration fails, a default protocol stack of the multiple supported protocol stacks is restored by the AP and / orthe Modem is reset. The invention further discloses an application processor and a mobile terminal. The method is advantaged in that detection and recovery of network abnormality can be rapidly carried out.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a method for processing abnormalities in network communication functions, an application processor and a mobile terminal. Background technique [0002] With the development of communication technology, there are more and more types of communication standards supported by mobile phones. For example, a mobile phone supports 2G, 3G, and 4G communication standards of different operators at the same time, eliminating the inconvenience of replacing mobile phones. The rapid development of the mobile Internet makes data services occupy an absolute proportion, so the role and status of modems in mobile phones are becoming increasingly important. Modems are used to convert data to be sent into radio frequency signals and radio frequency signals to data to be processed, processing AS (Access Stratum) , The access layer, referred to as AS) and NAS (Non Access Stratum, referred to as NAS) sign...

AI Technical Summary

Problems solved by technology

It can solve the problem that in the prior art, when the data service is abnormal and cannot be connected to the network, it cannot automatically try to recover or the recovery of the communication service takes too long.
