Whether the abnormal cause of S310, MT/MO call failure reports.
Concrete, if the abnormal cause of MT/MO call failure reported, then perform S301, after the abnormal cause of MT/MO call failure 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 MT/MO call failure, then continue to perform the subsequent steps such as S302.Otherwise, perform S311.
S311, the abnormal cause obtaining described MT/MO call failure and daily record.
S312, described abnormal cause, described current positional information and daily record are reported network side and/or user.
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 MT/MO call failure, then continue to perform the subsequent steps such as S302.
By the mode of circulation, can guarantee the solution of MT/MO call failure problem, after Resolving probiems, modulator-demodulator can not detect MT/MO call failure again, and terminal can recover normal work.
Implement embodiments of the invention, application processor receives the abnormal Indication message sent when modulator-demodulator detects MT/MO call failure, 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 successful registration during network, record current positional information, and during network failure, recover default protocol stack switch state or restart modulator-demodulator simultaneously when change in location and on registering.Cannot be detected fast during proper communication at modulator-demodulator like this, and the mode of carrying out network registry by switching other protocol stacks makes modulator-demodulator recover the normal of communication automatically, avoid the hand-operated forced consuming time long problem of restarting mobile phone or location updating and causing, decrease the time of network disaster recovery.
