Processing method for network communication function exception, application processor and mobile terminal

Abstract

The embodiments of the present invention disclose a processing method for a network communication function exception. The method comprises the steps that: an application processor acquires a first protocol stack currently used by a modem after receiving exception indication information sent from the modem, wherein the exception indication information indicates that the modem detects an MT / MO call failure; the application processor disenables the first protocol stack and selects a second protocol stack other than the first protocol stack from a plurality of protocol stacks supported by the modem; the application processor enables the second protocol stack and uses the second protocol stack to perform network registration; and the application processor records current position information when network registration is successful. The embodiments of the present invention further disclose an application processor and a mobile terminal. The method provided by the present invention can be used for quickly detecting and recovering from the network communication function exception.

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 changing mobile phones. The rapid development of mobile Internet makes data services take an absolute proportion, so the role and status of modems in mobile phones are becoming more and more important. Modems are used to convert data to be sent into radio frequency signals and radio frequency signals to data to be processed, processing access layer (AS) and non-access stratum (NAS) signaling, and interface with AP processor, etc. The mobile network en...
