Whether S309, positional information change.
Concrete, application processor periodically obtains positional information, current acquisition positional information and on the positional information that once obtains compare change time, if the judged result of S309 is yes, execution S310; If the judged result of S309 is no, continue to perform S309.Such as, positional information is cell ID, and mobile terminal moves to another community by a community, represents that positional information changes; Positional information is location area code, and mobile terminal moves to another band of position by a band of position, shows that positional information changes.Cycle the present invention that application processor obtains positional information is not restricted, and can arrange according to the actual requirements.
S310, described application processor recover the on off state of the default protocol stack in multiple protocol stacks of described support and/or the described modulator-demodulator that resets.
Concrete, application processor obtains the initial switch state that in the multiple protocol stacks supported before modulator-demodulator detects internal storage access mistake, each protocol stack is corresponding, and current switch states corresponding for each protocol stack in the multiple protocol stacks supported is returned to initial switch state.Multiple protocol stacks of modulator-demodulator support only have a protocol stack to be opening at every turn, and remaining protocol stack is closed condition.
Whether the abnormal cause of S311, internal storage access mistake reports.
Concrete, the abnormal cause of internal storage access mistake can be represented by reason-code, the reason-code that different abnormal causes is corresponding different, the mode that abnormal cause describes by text simultaneously represents, if the abnormal cause of internal storage access mistake reported, continue to perform S301, after the abnormal cause of internal storage access mistake had reported, user can carry out adjusting or repairing according to abnormal cause, continuing to jump to S301 is afterwards detected abnormal by modulator-demodulator, if modulator-demodulator still detects internal storage access mistake, then continue to perform the subsequent steps such as S302.If the judged result of S311 is no, perform S312.
S312, the abnormal cause obtaining described internal storage access mistake and daily record.
Wherein, daily record represents the operation information of modem access internal memory, and operation information comprises: operational order, operating time and return results.
S313, described abnormal cause, described current positional information and daily record are reported network side and/or show described abnormal cause.
Concrete, abnormal cause, current positional information and daily record are reported network side by application processor, wherein, can when on mobile terminal connects when wifi hotspot, by wifi hotspot by above-mentioned information reporting to network side, to save flow.Or abnormal cause also can be presented on the display screen of mobile terminal by application processor, checks for user.
After above-mentioned information reporting, can step S301 be jumped to equally, be detected by modulator-demodulator abnormal, if modulator-demodulator still detects internal storage access mistake, then continue to perform the subsequent steps such as S302.
By the mode of circulation, can guarantee the solution of internal storage access Problem-Error, after Resolving probiems, modulator-demodulator can not detect internal storage access mistake again, and mobile terminal can recover normal work.
Implement embodiments of the invention, application processor receives the abnormal Indication message sent when modulator-demodulator detects internal storage access mistake, close the protocol stack of current use, other protocol stacks of the protocol stack of current use are selected from the multiple protocol stacks supported, open other protocol stacks and use other protocol stack registered networks, on registering during network, recording current positional information, on unregistered during network, recover default protocol stack and also restart modulator-demodulator.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.
