Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
It is that a kind of flow of processing method of network communicating function exception provided in an embodiment of the present invention is illustrated referring to Fig. 1
Figure, in embodiments of the present invention, the method includes the steps：
After the abnormal instruction message that S101, the application processor receiving modem are sent, judge in preset time
Whether the interior number that network communicating function exception occurs is more than or equal to preset times threshold value, if so, obtaining the modulation
The first currently used protocol stack of demodulator.
Specifically, application processor full name is AP (Application Processor, application processor, abbreviation AP), use
It is in smart mobile phone in the super large-scale integration that audio and video function and special purpose interface are extended on the basis of low power consumption CPU
Important component, application processor is general and baseband processor is two independent chips.Modem is used to believe base band
Number radiofrequency signal is converted to, radiofrequency signal is converted to baseband signal, the letter of processing access layer (AS) and Non-Access Stratum (NAS)
It enables and with AP processors into line interface etc.；Modem supports various protocols stack.It, can when modem occurs abnormal
Network registry is carried out by the various protocols stack of its support, to restore data service.When modem detects generation network
After communication function exception, modem can collapse, and can not be normally carried out data processing, user is caused to cannot get online.
In order to restore proper network, modem then needs the reason of abnormal to network communicating function to judge, and then can basis
Concrete reason carries out network restoration.Specifically, modem can judge to cause net when detecting network communicating function exception
Whether the reason of network communication function is abnormal is channel decoding failure, if abnormal instruction message then can be transmitted to application processor,
Inform that application processor detects channel decoding failure by above-mentioned abnormal instruction message.Application processor passes through modem
The abnormal instruction message of transmission determine the reason of network communicating function is abnormal for channel decoding failure after, then can to network into
Row is repaired.
In some feasible embodiments, application processor determines that the abnormal cause of network communicating function exception is channel
It after decoding failure, can determine whether within the preset time, the network communicating function frequency of abnormity for channel decoding failure occur is
