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

Abstract

The embodiment of the invention discloses a processing method for a network communication function abnormality. The processing method comprises the following steps: after receiving an abnormal indication message transmitted by a modem by an application processor, acquiring a first protocol stack currently used by the modem, wherein the abnormal indication message means that the modem detects a memory access error; closing the first protocol stack by the application processor, and selecting a second protocol stack except the first protocol stack from a plurality of protocol stacks which are supported by the modem; opening the second protocol stack by the application processor, and using the second protocol stack to perform network registration; and if the network registration is successful, recording current position information by the application processor. The embodiment of the invention further discloses the application processor and a mobile terminal. By adopting the processing method for the network communication function abnormality, the application processor and the mobile terminal provided by the invention, the abnormality of the network can be detected and recovered quickly.

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 modems in mobile phones are becoming increasingly important. Modems are used to convert data to be sent into radio frequency signals and device signals into data to be processed. AS (AccessStratum, The access stratum, referred to as AS) and NAS (NonAccessStratum, non-access stratum, referred to as NAS) signaling, and the interface with the A...
