Processing method of network communication function abnormity, modem and mobile terminal

Abstract

The embodiment of the invention discloses a processing method of network communication function abnormity. The method comprises the following steps: judging whether a reason causing the abnormity of the network communication function is channel decoding failure when a modem detects the abnormity of the network communication function; if the reason causing the abnormity of the network communication function is the channel decoding failure, the modem closing a current used first protocol stack, and selecting a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem; opening the second protocol stack, and performing the network registration through the adoption of the second protocol stack; if the network registration is successful, the modem recording the current position information; if the network registration fails, the modem resetting the modem while recovering the on-off status of the default protocol stack in the plurality of supported protocol stacks. The embodiment of the invention further discloses a modem and a mobile terminal. The abnormity of the network can be fast detected and recovered through the adoption of the method disclosed by the invention.

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. The mobile network environment where the mobi...

Problems solved by technology

It can solve the problem that in the prior art, when an abnormality occurs and the communication cannot be connected to the network, it cannot automatically try to recover or the recovery of the communication service takes too long.
