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

Abstract

The embodiment of the invention provides a network communication function abnormality processing method, an application processor and a mobile terminal. The method comprises that: when the application processor receives an abnormality message with a network abnormality cause sent by a modulator-demodulator, the first protocol stack currently used by the modulator-demodulator is obtained; when the number of the generation times of the network abnormality cause is judged to reach preset times within a preset time period, the application processor 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 application processor opens the second protocol stack and carries out network register again through the second protocol stack; when the network register is successful, the application processor records the current position. The embodiment of the invention also discloses a modulator-demodulator and a user terminal. In application of the embodiment of the invention, the network abnormality resulted from PND connection failure can be quickly recovered, the communication function can be recovered timely, and the network abnormality recovering time is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for processing abnormal network communication functions, an application processor and a mobile terminal. Background technique [0002] With the rapid development of the fourth generation mobile communication technology (4G), there are more and more mobile terminals that support 4G communication standards, and mobile terminals that support 4G communication standards also support 2G and 3G communication standards to ensure the normal communication of users . The rapid development of mobile communication technology has made data services occupy an absolute proportion, so the role and status of modems in mobile terminals are becoming increasingly important. Modems are used to convert data to be sent into radio frequency signals and convert radio frequency signals Access stratum (AS) and non-access stratum (NAS) signaling, and interface with AP processor, etc. [000...
