Method for processing abnormality of network communication function, application processor and mobile terminal

Abstract

The embodiment of the invention discloses a processing method of network communication function abnormity. The method comprises the following steps: determining an abnormal reason of a memory access error when an AP receives abnormal indication information sent by a modem while detecting the memory access error; if the occurrence frequency of the same abnormal reason in a preset duration reaches a preset frequency, the AP acquiring the first protocol stack currently used by the modem; the AP closing the first protocol stack, and selecting a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem; the AP opening the second protocol stack, and performing the network registration through the adoption of the second protocol stack; if the network registration is successful, the AP recording the current position information; if the network registration fails, the AP recovering the default protocol stack in the plurality of supported protocol stacks and / or resetting the modem. The embodiment of the invention further discloses an application processor and a mobile terminal. And the abnormity of the network can be fast detected and recovered through the adoption of the method disclosed by the invention.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for processing abnormal network communication functions, an application processor and a mobile terminal. Background technique [0002] With the development of communication technology, mobile phones support more and more types of communication systems. For example, a mobile phone supports 2G, 3G and 4G communication systems of different operators at the same time, saving the inconvenience of changing mobile phones. The rapid development of the mobile Internet has made data services occupy an absolute proportion, so the role and status of the modem in the mobile phone is becoming increasingly important. The modem is used to convert the data to be sent into radio frequency signals and convert radio frequency signals , access stratum, referred to as AS) and NAS (Non Access Stratum, non-access stratum, referred to as NAS) signaling, and the interface with the AP application proc...

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.
