Method for handling abnormal network communication function, modem and mobile terminal

Abstract

The embodiment of the invention discloses a network communication function abnormity processing method, and the method comprises the steps: obtaining a first protocol stack employed by the modem currently after the modem detects that the registration of the protocol stack is rejected; enabling the modem to turn off the first protocol stack, and selecting a second protocol stack, except the first protocol stack, from a plurality of protocol stacks supported by the modem; enabling the modem to start the second protocol stack, and carrying out the network registration of the second protocol stack; and enabling the modem to record the current position information if the network registration is successful. The embodiment of the invention also discloses the modem and the mobile terminal. According to the invention, the method can achieve the quick detection of the abnormality of the network communication function and quick recovery of the network communication function.

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 ...
