Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, the schematic flow sheet of the processing method of a kind of network communicating function exception provided for the embodiment of the present invention, in embodiments of the present invention, described method comprises step:
After the abnormal Indication message that S101, described application processor receiving modem send, judge whether the number of times that network communicating function exception occurs in Preset Time is greater than or equal to preset times threshold value, if so, the first protocol stack of the current use of described modulator-demodulator is then obtained.
Concrete, application processor full name is AP (ApplicationProcessor, application processor, be called for short AP), for expanding the very lagre scale integrated circuit (VLSIC) of audio frequency and video function and special purpose interface on the basis of low power consumption CPU, be the vitals in smart mobile phone, the general and baseband processor of application processor is independently two chips.Modulator-demodulator is used for baseband signal being converted to radiofrequency signal, radiofrequency signal is converted to baseband signal, processes the signaling of Access Layer (AS) and Non-Access Stratum (NAS) and carry out interface etc. with AP processor; Various protocols stack supported by modulator-demodulator.When modulator-demodulator occurs abnormal, the various protocols stack supported by it carries out network registry, to recover data service.After modulator-demodulator detects that generation network communicating function is abnormal, modulator-demodulator can collapse, and normally cannot carry out data processing, cause user could not get on to the Net.In order to recover proper network, modulator-demodulator then needs to judge the reason of network communicating function exception, and then can carry out network restoration according to concrete reason.Concrete, modulator-demodulator can when detecting that network communicating function is abnormal, judge to cause the reason of network communicating function exception whether to be channel-decoding failure, if abnormal Indication message then can be sent to application processor, inform that application processor detects channel-decoding failure by above-mentioned abnormal Indication message.Application processor then can be repaired network after being channel-decoding failure by the reason that the abnormal Indication message that modulator-demodulator sends determines network communicating function exception.
In the execution mode that some are feasible, the abnormal cause of application processor determination network communicating function exception is after channel-decoding failure, can judge within the time preset, occur whether the network communicating function frequency of abnormity of channel-decoding failure is greater than or equal to preset times threshold value, if so, then need to process above-mentioned network communicating function is abnormal.That is, modulator-demodulator can repeatedly because channel-decoding unsuccessfully occurs that network communicating function carry out network communicating function abnormality processing time abnormal, avoid network occur false abnormal time carry out network processes, waste resource.
It should be noted that, modulator-demodulator can be integrated in the inside of application processor AP, and also can be a chip independent of application processor, the present invention be restricted.

In the execution mode that some are feasible, the first protocol stack is the protocol stack causing channel-decoding failure, and application processor needs closedown first protocol stack, prevents channel-decoding failure from repeatedly occurring.Application processor selects one except the second protocol stack of the first protocol stack from multiple protocol stacks that modulator-demodulator is supported.
S103, described application processor open described second protocol stack, and use described second protocol stack to carry out network registry.
In the execution mode that some are feasible, after closing the first protocol stack, mobile terminal becomes without service state, application processor opens the second protocol stack selected, second protocol stack is used to carry out network registry, the process of network registry is: mobile terminal initiates attachment request (attacherequest) to network side, if network side allows mobile terminal access, attachment response (attachaccept) is returned to mobile terminal, represent network registry success, mobile terminal has been converted to service state by without service state; If network side does not allow mobile terminal to access, return error message to mobile terminal, represent network registry failure.
If the success of S104 network registry, the positional information that described application processor record is current.
In the execution mode that some are feasible, positional information represents mobile terminal logical place in the mobile communication network, and positional information can be cell ID or regional location code or position tracing area etc., and the present invention is not restricted.If use the success of second protocol stack registered network, record current positional information.
If the failure of S105 network registry, the default protocol stack switch state in the described multiple protocol stack of described application processor recovery or the described modulator-demodulator that simultaneously resets.
In the execution mode that some are feasible, default protocol stack is the protocol stack pre-set, and default protocol stack is one in multiple protocol stacks of modulator-demodulator support.If use the failure of second protocol stack registered network, the default protocol stack that unlatching pre-sets also carries out reset operation to modulator-demodulator, and after reset operation, modulator-demodulator uses default protocol stack to carry out work.
Implement embodiments of the invention, application processor receives the abnormal Indication message sent when modulator-demodulator detects channel-decoding failure, close the protocol stack of the current use of modulator-demodulator, other protocol stacks of the protocol stack of current use are selected from multiple protocol stacks of modulator-demodulator support, open other protocol stacks and use other protocol stack registered networks, on registering during network, record current positional information.Be detected fast when modulator-demodulator cannot normally work like this, and make modem recovery normal by the mode of network registry, avoid forcing restarting the consuming time long problem that mobile phone or location updating cause, decrease the time of network disaster recovery.
