Network communication function abnormality processing method, modulator-demodulator and user terminal

Abstract

The embodiment of the invention discloses a network communication function abnormality processing method, comprising that: when the modulator-demodulator detects a network abnormality cause, the network abnormality cause is position updating failure; the modulator-demodulator judges whether the number of the generation times of the network abnormality cause reaches a threshold value within a preset time period; if it is, the modulator-demodulator closes the first protocol stack, a second protocol stack is selected from a plurality of protocol stacks supported by the modulator-demodulator in addition to the first protocol stack; the modulator-demodulator opens the second protocol stack and carries out network register again through the second protocol stack; if the network register is successful, the modulator-demodulator records the current position. The embodiment of the invention also discloses a modulator-demodulator and a user terminal. In application of the invention, the network communication function abnormality can be quickly detected and recovered.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for processing abnormal network communication functions, a modem and a user terminal. Background technique [0002] With the development of mobile communication technology, there are more and more types of communication systems supported by mobile phones. For example, a mobile phone can support 2G, 3G and 4G communication systems of different operators at the same time. The rapid development of mobile communication technology 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 convert radio frequency signals into data to be processed and process access Layer (AS) and non-access stratum (NAS) signaling, and interface with the AP processor, etc. [0003] In daily life, mobile phones are always in an env...
