Network communication function anomaly processing method, application processor and mobile terminal

Abstract

The embodiment of the invention discloses a network communication function anomaly processing method. The method comprises the following steps that: after an application processor receives an anomalous indication message sent by a modem, a judgment on whether an anomalous situation under which protocol stack registration is rejected for set times within a set time or not, and a first protocol stack currently used by the modem is acquired if a judgment result is positive, wherein the anomalous indication message indicates that rejection of the protocol stack registration is detected by the modem; the application processor disables 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 performs network registration with the second protocol stack; and if the network registration succeeds, the application processor records current position information. The embodiment of the invention also discloses the application processor and the mobile terminal. Through adoption of the method, the application processor and the mobile terminal, network communication function anomalies can be rapidly detected and recovered.

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 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 e...
