Abstract

The embodiment of the present invention discloses a method for processing abnormalities in network communication functions, including: the modem detects the abnormality caused by the crash of the currently used protocol stack, and determines that the currently used protocol stack is the first protocol stack; the modem closes the first protocol stack; A protocol stack, and select a second protocol stack except the first protocol stack from multiple protocol stacks supported by the modem; the modem enables the second protocol stack, and uses the second protocol stack to perform Network registration; if the network registration is successful, the modem records the current location information; if the network registration fails, the modem restores the switch state of the default protocol stack in the supported multiple protocol stacks or restores the supported multiple switch state of the default protocol stack in the protocol stack and reset the modem at the same time. The embodiment of the invention also discloses a modem and a mobile terminal. By adopting the invention, the abnormality of the network can be quickly detected and recovered.

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...
