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

Abstract

The present invention provides a method for processing abnormalities in network communication functions, comprising: an application processor receives abnormality indication information sent by a modem, and the abnormality indication information is used to instruct the modem to detect a network abnormality caused by network registration failure; The instruction information judges whether a preset number of network abnormalities caused by network registration failures occur within a preset time; if it is judged to be yes, the application processor obtains the first protocol stack currently in use; the application processor closes the first protocol stack, Open the second protocol stack for network registration; if the network registration is successful, the application processor obtains the current location information; if the network registration fails, the application processor restores the switch state of the default protocol stack and / or resets the modem. The embodiment of the invention also discloses an application processor and a mobile terminal. By adopting the invention, the recovery time of data service can be shortened.

Description

technical field [0001] The invention relates to the field of communication technology, 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, there are more and more types of communication systems supported by mobile phones. For example, a mobile phone can support 2G, 3G and 4G communication systems of different operators at the same time, which can meet the needs of communication in different communication environments. standard requirements. 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...
