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

Abstract

The embodiment of the invention discloses a network communication functional abnormity processing method. The network communication functional abnormity processing method comprises: acquiring the first protocol stack used by a modem at present after an application processor receives the abnormal indication information sent from the modem; closing the first protocol stack by the application processor, and selecting the second protocol stack except for the first protocol stack among a plurality of protocol stacks supported by the modem; starting the second protocol stack by the application processor, and using the second protocol stack to perform network registration; if network registration is successful, recording the current location information by the application processor; and if network registration fails, recovering the on / off state of the default protocol stack in the plurality of protocol stacks or restoring the modem by the application processor at the same time. The embodiment of the invention also discloses an application processor and a mobile terminal. The network communication functional abnormity processing method, the application processor and the mobile terminal can quickly detect and restore from abnormity of network.

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 device signals into data to be processed and process the access layer. (AS) and non-access stratum (NAS) signaling, and interface with the AP processor, etc. The mobile network environme...
