Processing method for network communication function abnormity, modem and mobile terminal

Abstract

The embodiment of the invention discloses a processing method for an abnormal network communication function, a modem and a mobile terminal. The method comprises the following steps: after detecting by a modem that a protocol stack registration is rejected, judging whether an abnormal condition that the protocol stack registration is rejected for a set number of times occurs within a set time, if so, then acquiring a first protocol stack currently used by the modem; closing the first protocol stack by the modem, 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 modem, and using the second protocol stack to perform network registration; and if the network registration is successful, then recording current position information by the modem. The embodiment of the invention further discloses the modem and a mobile terminal. By adopting the processing method for the abnormal network communication function, the modem and the mobile terminal provided by the invention, the abnormity of the network communication function can be detected and restored quickly.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for processing abnormal network communication functions, a modem 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 environment where ...
