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:
The protocol stack that S101, modulator-demodulator detect current use crashes the exception caused, and determines that the protocol stack of current use is the first protocol stack.
Concrete, application processor full name is MAP (MultimediaApplicationProcessor, multimedia application processor, be called for short MAP), 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 (ModulatorandDemodulator is called for short Modem) is for being converted to radiofrequency signal, radiofrequency signal being converted to baseband signal, processing the signaling of Access Layer (AS) and Non-Access Stratum (NAS) and carry out interface etc. with AP processor by baseband signal; Various protocols stack supported by modulator-demodulator.Protocol stack represents the summation of the various protocols that certain communication standard is corresponding, such as: protocol stack comprises global system for mobile communications (GlobalSystemforMobileCommunication, be called for short GSM) protocol stack, enhanced data rates for gsm evolution technology (EnhancedDataRateforGSMEvolution, be called for short EDGE) protocol stack, high speed downlink packet access technology (HighSpeedDownlinkPacketAccess, be called for short HSPDA) protocol stack, CDMA (Code Division Multiple Access) (the TimeDivision-SynchronousCodeDivisionMultipleAccess of time division synchronous, be called for short TD-SCDMA) protocol stack, time division duplex Long Term Evolution LTE (Time-DivisionDuplexLongTermEvolution, be called for short TDD-LTE) protocol stack, Frequency Division Duplexing (FDD) Long Term Evolution (Frequency-DivisionDuplex, be called for short FDD-LTE) protocol stack etc., multiple sub-protocol stack is comprised again below each communication standard protocol stack, such as TD-LTE protocol stack comprises again physical layer protocol stack, media access control layer (MediaAccessControl, be called for short MAC) protocol stack, wireless spread-spectrum technology (RadioLinkControl, be called for short RLC) protocol stack, wireless heterogeneous networks (RadioResourceContro, be called for short RRC) protocol stack and network attached storage (NetworkAttachedStorage, be called for short NAS) protocol stack etc., repeat no more herein.
It should be noted that, modulator-demodulator can be integrated in the inside of application processor, and also can be a chip independent of application processor, the present invention be restricted.
Modulator-demodulator is when detecting abnormal, first can determine the first protocol stack of current use, and determine whether that the first protocol stack crashes the exception caused, or, first can determine whether that protocol stack crashes the exception caused, and then determine the first protocol stack of current use.
If described first protocol stack crashes and causes abnormal number of times to be greater than default number of times in S102 Preset Time, described modulator-demodulator cuts out described first protocol stack, and removes the second protocol stack of described first protocol stack from the selection multiple protocol stacks that described modulator-demodulator is supported.
In concrete enforcement, modulator-demodulator can record each protocol stack and abnormal time and abnormal cause occur, and comprises the first protocol stack deadlock and causes abnormal time and number of times.According to record, can judge that in Preset Time, the first protocol stack deadlock causes abnormal number of times whether to be greater than default number of times.Wherein, Preset Time and default number of times are the parameter pre-set.
Concrete, if the first protocol stack crashes and causes abnormal number of times to be greater than default number of times in Preset Time, represent that the first protocol stack often crashes at short notice, then modulator-demodulator needs cut out first protocol stack, the problem preventing protocol stack from crashing occurs repeatedly, and opens other protocol stacks to connect mobile network.Modulator-demodulator can select one except the second protocol stack of the first protocol stack from the multiple protocol stacks supported, wherein second protocol stack should be crash to cause abnormal number of times to be less than or equal to the protocol stack of described default number of times in Preset Time.
In the execution mode that some are feasible, the strategy that modulator-demodulator is selected can be: the protocol stack of the low one-level of Selection radio first protocol stack is as second protocol stack; Or measure the signal strength signal intensity of the cell signal that each protocol stack is corresponding around, using protocol stack maximum for signal strength signal intensity as second protocol stack; Or the higher leveled protocol stack of Selection radio first protocol stack is as second protocol stack; Or adopting other strategy to determine second protocol stack, the present invention is not restricted.
Described second protocol stack opened by S103, described modulator-demodulator, and uses described second protocol stack to carry out network registry.
Concrete, after closing the first protocol stack, mobile terminal is converted to without service state by there being service state, the second protocol stack selected opened by modulator-demodulator, second protocol stack is used to carry out network registry, the process registered of such as LTE network as: mobile terminal initiates attachment request (attachrequest) to network side, if network side allows mobile terminal access, attachment response (attachresponse) 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 refusal/error message to mobile terminal, represent network registry failure.
If the success of S104 network registry, the positional information that described modulator-demodulator record is current.
Concrete, 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, then record current positional information.
If the failure of S105 network registry, the on off state of the default protocol stack in the multiple protocol stacks supported described in the on off state of the default protocol stack in the multiple protocol stacks supported described in described modem recovery or described modem recovery the described modulator-demodulator that simultaneously resets.
Concrete, default protocol stack is one in multiple protocol stacks of modulator-demodulator support, it is the protocol stack pre-set, the protocol stack that the protocol stack that can arrange same acquiescence for all regions herein uses as modulator-demodulator initial selected, also can arrange different default protocol stacks respectively for single area or the multiple areas being in a certain region, the embodiment of the present invention is not limited in any way.Wherein, a kind of feasible execution mode is: can the priority level of each protocol stack of Premises modem, such as: the priority level that can arrange each protocol stack when modulator-demodulator dispatches from the factory; Or, can be configured in mobile terminal at modulator-demodulator and carry out in initialized process, use network during each protocol stack to connect according to mobile terminal and network signal intensity situation arranges priority level; Etc..Another kind of feasible execution mode is: the priority level that can adjust each protocol stack of modulator-demodulator flexibly, such as: network during each protocol stack can be used to connect in certain band of position according to mobile terminal and network signal intensity situation arranges priority level; Or, the priority level of each protocol stack can be set according to the order of the conventional network formats of mobile terminal; Wait for.It should be noted that, the priority level of certain protocol stack is higher, illustrates that mobile terminal can obtain better network based on this protocol stack and connect or stronger network signal.Modulator-demodulator medium priority not the highest protocol stack is commonly called default protocol stack, and modulator-demodulator is also realize the network registry of mobile terminal and Web vector graphic according to priority level from height to low each protocol stack that uses in order usually.
If use network in the unsuccessful registration of second protocol stack, modulator-demodulator, according to default protocol stack switch state known in advance, recovers default protocol stack switch state or carries out reset operation to modulator-demodulator simultaneously.After reset operation, modulator-demodulator uses default protocol stack to carry out work.Be understandable that, default protocol stack herein both may be the first protocol stack, also may be other protocol stacks beyond the first protocol stack.It should be noted that, if default protocol stack is the first protocol stack (namely pent, cause dedicated bearer process to produce abnormal protocol stack) in the present embodiment, so, this step is equivalent to reopen the first protocol stack.
Implement embodiments of the invention, the protocol stack that modulator-demodulator detects current use crashes the exception caused, and determine that the protocol stack of current use is the first protocol stack, if described first protocol stack crashes and causes abnormal number of times to be greater than default number of times in Preset Time, close the first protocol stack of current use, other protocol stacks except the first protocol stack of current use are selected from multiple protocol stacks that modulator-demodulator is supported, open other protocol stacks and use other protocol stack registered networks, on registering during network, record current positional information, when network registry failure, the on off state recovering the default protocol stack in multiple protocol stacks of described support or the on off state recovering the default protocol stack in multiple protocol stacks of described support the described modulator-demodulator that simultaneously resets.Like this modulator-demodulator cannot proper communication time normal by what change that protocol stack re-starts that the mode of network registry makes modem autorecovery communicate, avoid forcing restarting the consuming time long problem that mobile phone or location updating cause, decrease the time of network disaster recovery.
See Fig. 2, another 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:
S201, modulator-demodulator judge the network parameter that the protocol stack whether comprising current use in community, current place or current connect network of network parameter is not supported.If be judged as YES, perform step S202; Otherwise continue to perform this step S201.
Concrete, modulator-demodulator is arranged in mobile phone, can be encapsulated as in modulator-demodulator, or independent of modulator-demodulator, the present invention is not restricted.Modulator-demodulator is used for the mutual conversion between baseband signal and radiofrequency signal, is mainly used in network communicating function.
Concrete, protocol stack represents the summation of the various protocols stack that certain communication standard is corresponding, such as: protocol stack comprises gsm protocol stack, EDGE protocol stack, HSPDA protocol stack, TD-SCDMA protocol stack, TDD-LTE protocol stack, FDD-LTE protocol stack etc., multiple sub-protocol stack is comprised again, such as: TD-LTE protocol stack comprises again physical layer protocol stack, media access control layer MAC protocol stack, wireless spread-spectrum technology rlc protocol stack, RRC protocol stack, PDCP protocol stack and NAS protocol stack etc. below each communication standard protocol stack.Repeat no more herein.
In the execution mode that some are feasible, protocol stack can check signaling parameter in communication protocol and parameter combinations in running, different to the configuration of these parameters in different networks or community.When the parameter of certain community or network configuration exceeds the parameter that protocol stack supports, protocol stack can be caused to crash.Therefore, modulator-demodulator can judge the network parameter that the protocol stack whether comprising current use in community, current place or current connect network of network parameter is not supported, if be judged as YES, then may be that the protocol stack of current use crashes the exception caused.In addition, some protocol stacks are failed the leak of the EMS memory error that detects in advance or protocol stack itself protocol stack also may be caused to crash.Wherein common EMS memory error can comprise memory overflow, memory overwriting is accessed, quote wild pointer, access no initializtion variable, stack overflow, byte-aligned problem etc.
Alternatively, modulator-demodulator, when detecting abnormal, first can determine the first protocol stack of current use, and determine whether that the first protocol stack crashes the exception caused, or, first can determine whether that protocol stack crashes the exception caused, and then determine the first protocol stack of current use.
S202, described modulator-demodulator judge that abnormal cause causes exception as the protocol stack deadlock of described current use.
According to the current wireless access technology RAT registered, S203, described modulator-demodulator determine that the protocol stack of current use is as the first protocol stack.
In the execution mode that some are feasible, modulator-demodulator can determine described first protocol stack according to the wireless access technology (RadioAccessTechnology, RAT) of current registration.Or, the first protocol stack can be determined according to the filename that abnormal source file occurs, such as, if source filename is lte_rrc.c, can judge that the first protocol stack is lte protocol stack according to keyword lte wherein.
In the execution mode that other are feasible, the method that modulator-demodulator obtains the first protocol stack of the current use of modulator-demodulator can be: in modulator-demodulator inquiry modulator-demodulator, the state flag bit of presentation protocol stack obtains the first protocol stack of current use, such as flag bit 1 represents that corresponding protocol stack is opening, and flag bit 0 represents that corresponding protocol stack is closed condition.
S204, described modulator-demodulator judge that in Preset Time, described first protocol stack deadlock causes abnormal number of times whether to be greater than default number of times; If be judged as YES, perform step S205, otherwise reset modulator-demodulator.
In concrete enforcement, modulator-demodulator can record each protocol stack and abnormal time and abnormal cause occur, and comprises the first protocol stack deadlock and causes abnormal time and number of times.According to record, can judge that in Preset Time, the first protocol stack deadlock causes abnormal number of times whether to be greater than default number of times.Wherein, Preset Time and default number of times are the parameter pre-set.
Concrete, if the first protocol stack deadlock causes abnormal number of times to be greater than default number of times in Preset Time, represent that the first protocol stack often crashes at short notice, can step S205 be performed.If the first protocol stack deadlock causes abnormal number of times to be less than or equal to default number of times in Preset Time, represent the number of times that the first protocol stack occurs to crash at short notice and infrequently, now attempt solving extremely by reset modulator-demodulator.
Described first protocol stack closed by S205, described modulator-demodulator, and selects the second protocol stack except described first protocol stack from multiple protocol stacks that described modulator-demodulator is supported.
Concrete, if the first protocol stack crashes and causes abnormal number of times to be greater than default number of times in Preset Time, represent that the first protocol stack often crashes at short notice, then modulator-demodulator needs cut out first protocol stack, the problem preventing protocol stack from crashing occurs repeatedly, and opens other protocol stacks to connect mobile network.Modulator-demodulator can select one except the second protocol stack of the first protocol stack from the multiple protocol stacks supported, wherein second protocol stack should be crash to cause abnormal number of times to be less than or equal to the protocol stack of described default number of times in Preset Time.
In the execution mode that some are feasible, the strategy that modulator-demodulator is selected can be: the protocol stack of the low one-level of Selection radio first protocol stack is as second protocol stack; Or measure the signal strength signal intensity of the cell signal that each protocol stack is corresponding around, using protocol stack maximum for signal strength signal intensity as second protocol stack; Or the higher leveled protocol stack of Selection radio first protocol stack is as second protocol stack; Or adopting other strategy to determine second protocol stack, the present invention is not restricted.
Described second protocol stack opened by S206, described modulator-demodulator, and uses described second protocol stack to carry out network registry.
Concrete, after closing the first protocol stack, mobile terminal is converted to without service state by there being service state, the second protocol stack selected opened by modulator-demodulator, second protocol stack is used to carry out network registry, the process registered of such as LTE network as: move to network side and initiate attachment request (attachrequest), 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 refusal/error message to mobile terminal, represent network registry failure.
S207, described modulator-demodulator judge that whether network registry is successful, if so, forward S208 to, otherwise forward S209 to.
Concrete, if modulator-demodulator uses network on second protocol stack successful registration, then perform S208, if modulator-demodulator uses network in the unsuccessful registration of second protocol stack, then perform S209.
The positional information that S208, described modulator-demodulator record are current, then performs S210.
Concrete, positional information represents the mark of the logical place planned in advance in mobile communications network, and such as, positional information comprises cell ID or location area code etc.
The on off state of the default protocol stack in the multiple protocol stacks supported described in the on off state of the default protocol stack in the multiple protocol stacks supported described in S209, described modem recovery or described modem recovery the described modulator-demodulator that simultaneously resets.
Concrete, registered network, then modulator-demodulator determination default protocol stack if modulator-demodulator use second protocol stack fails, recover default protocol stack and send reset instruction to carry out reset operation to modulator-demodulator.Default protocol stack is a protocol stack pre-set in multiple protocol stacks of modulator-demodulator support.After carrying out reset operation, modulator-demodulator uses default protocol stack to carry out network registry, after network registry success, uses default protocol stack to carry out work.
S210, described modulator-demodulator judge whether positional information changes; If the determination result is YES, perform step S211, otherwise continue to perform step S210.
Concrete, modulator-demodulator periodically obtains positional information, current acquisition positional information and on the positional information that once obtains compare change time, perform S211, otherwise continue acquisition positional information.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 modulator-demodulator obtains positional information is not restricted, and can arrange according to the actual requirements.
The on off state of the default protocol stack in the multiple protocol stacks supported described in the on off state of the default protocol stack in the multiple protocol stacks supported described in S211, described modem recovery or described modem recovery the described modulator-demodulator that simultaneously resets.
Implement embodiments of the invention, the protocol stack that modulator-demodulator detects current use crashes the exception caused, and determine that the protocol stack of current use is the first protocol stack, close the first protocol stack of current use, other protocol stacks except the first protocol stack of current use are selected from multiple protocol stacks that modulator-demodulator is supported, open other protocol stacks and use other protocol stack registered networks, on successful registration during network, record current positional information, and when change in location or network registry failure, the on off state of modem recovery default protocol stack or recover the on off state of the default protocol stack in multiple protocol stacks of described support and restart modulator-demodulator simultaneously.Like this modulator-demodulator cannot proper communication time normal by what change that protocol stack re-starts that the mode of network registry makes modem autorecovery communicate, avoid forcing restarting the consuming time long problem that mobile phone or location updating cause, decrease the time of network disaster recovery.
