Network communication function abnormity processing method, modulator-demodulator and mobile terminal

Abstract

The embodiment of the invention discloses a network communication function abnormity processing method, a modulator-demodulator and a mobile terminal. The method comprises following steps: by the modulator-demodulator, detecting abnormities caused by dead halt of a currently used protocol stack and determining the currently used protocol stack is a first protocol stack; if the number of times of abnormalities caused by the dead halt of the first protocol stack within preset time is greater than a preset number of times, closing the first protocol stack and selecting a second protocol stack, except for the first protocol stack, from multiple protocol stacks supported by the modulator-demodulator; opening the second protocol stack and performing network registration by using the second protocol stack; if the network registration is successful, recording current position information; if the network registration is failed, recovering the on / off state of a default protocol stack in the multiple supported protocol stacks or recovering the on / off state of the default protocol stack in the multiple supported protocol stacks and resetting the modulator-demodulator. By adoption of the network communication function abnormity processing method, network abnormities can be detected and recovered rapidly.

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 device 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. When the mobile network environment where the...
