Referring to fig. 1, fig. 1 is a flowchart illustrating a method for handling network communication function abnormality according to a first embodiment of the present invention. As shown in fig. 1, a method for processing a network communication function abnormality according to an embodiment of the present invention may include steps S101 to S104:
s101, the application processor receives an abnormal indication message sent by the modem when the modem detects that the state of the protocol stack is abnormal.
In the embodiment of the present invention, the application Processor is fully called a multimedia application Processor (MAP for short), and is an important component in a smart phone, where the application Processor is generally an independent chip from a baseband Processor, and is used for expanding an audio/video function and a very large scale integrated circuit of a dedicated interface on the basis of a low power consumption CPU. The modem is used for converting baseband signals into radio frequency signals, converting radio frequency signals into baseband signals, processing signaling of an Access Stratum (AS) and a non-access stratum (NAS), interfacing with an AP processor, and the like, and can support various protocol stacks. The abnormal state of the protocol stack means that a detection result of the current state context does not accord with a pre-expected result in the communication process, for example, when only an uplink data packet is detected in a period of time and no downlink data packet exists, the abnormal state of the protocol stack is considered (namely, an uplink and a downlink are not communicated); or, a User Equipment (UE) intelligent algorithm judges that the protocol stack is abnormal in operation according to the phenomenon of abnormal state; or, the communication process between the UE and the network side device is affected by the uncertain factor, and the UE is out of synchronization; and so on. When the modem detects that the state of the protocol stack is abnormal, the modem crashes and cannot process data normally, so that the UE cannot surf the internet. The protocol stack represents a sum of a plurality of protocols corresponding to a certain communication system. Optionally, the protocol stack includes a global system for Mobile communications (GSM) protocol stack, an enhanced data Rate for GSM Evolution (EDGE) protocol stack, a High Speed downlink packet Access (HSPDA) protocol stack, a Time Division Synchronous code Division Multiple Access (TD-SCDMA) protocol stack, a Time Division Long term Evolution (TDD-LTE) protocol stack, a Frequency Division duplex Long term Evolution (FDD-LTE) protocol stack, and the like, and the protocol stack includes Multiple sub-protocol stacks below each Communication system protocol stack, which is not described herein again. The modem determines a first protocol stack currently used when detecting a memory access error.
It should be noted that the modem may be integrated inside the application processor, or may be a chip independent from the application processor, and the present invention is not limited thereto.
S102, the application processor closes the first protocol stack causing the protocol stack state exception.
In the embodiment of the invention, some protocol stack state abnormity phenomena are common and easy to process, some protocol stack state abnormity phenomena are rare and difficult to process, and the difficult-to-process protocol stack state abnormity phenomena are released regardless of the further deterioration of the protocol stack error which can be caused and are difficult to control. To prevent protocol stack state exceptions from recurring or further deteriorating, the application processor needs to shut down the first protocol stack causing the protocol stack state exception.
S103, the application processor starts a second protocol stack, and performs network registration by using the second protocol stack, wherein the second protocol stack is a protocol stack other than the first protocol stack in a plurality of protocol stacks supported by the modem.
In the embodiment of the present invention, after the first protocol stack is closed, the UE is converted from the connection state to the idle state, the application processor selects the second protocol stack, the second protocol stack is a protocol stack other than the first protocol stack in the plurality of protocol stacks supported by the modem, and the application processor opens the second protocol stack and performs network registration using the second protocol stack. Optionally, a specific implementation manner of the network registration may be: the UE initiates an attach request (attach request) to the network side equipment, if the network side equipment allows the UE to access, an attach response (attach response) is returned to the UE, which indicates that the network registration is successful, and the UE is converted from an idle state to a connection state; and if the network side equipment does not allow the UE to access, returning error information to the UE, which indicates that the network registration fails. Optionally, the policy for the application processor to select the second protocol stack may be: selecting a protocol stack one level lower than the first protocol stack as a second protocol stack; or measuring the signal intensity of cell signals corresponding to each protocol stack supported by the modem, and taking the protocol stack with the maximum signal intensity as a second protocol stack; or selecting a protocol stack one level higher than the first protocol stack as a second protocol stack; alternatively, other strategies may be used to determine the second protocol stack, and the invention is not limited in this respect.
And S104, if the second protocol stack is successfully registered, the application processor records the current position information.
Optionally, the location information indicates a logical location of the UE in the mobile communication network, and the location information may be a cell identifier, an area location code, a location tracking area, or the like, which is not limited in the present invention. If the network registration using the second protocol stack is successful, the application processor records the current location information.
It can be seen that, in the embodiment of the present invention, the application processor receives an exception indication message sent by the modem when detecting that the state of the protocol stack is abnormal; the application processor closes a first protocol stack causing protocol stack state exception; the application processor starts a second protocol stack, and uses the second protocol stack to perform network registration, wherein the second protocol stack is a protocol stack except the first protocol stack in a plurality of protocol stacks supported by the modem; and if the second protocol stack is successfully registered, the application processor records the current position information. Therefore, when the abnormal state of the protocol stack causes the abnormal communication of the modem, the abnormal state of the protocol stack is quickly detected, and the communication of the modem is automatically recovered to be normal by switching other protocol stacks to perform network registration, so that the problem of overlong time consumption caused by manually and forcibly restarting a mobile phone or updating a position is avoided, and the time for recovering a network fault is shortened.
Optionally, the method for processing the network communication function abnormality shown in fig. 1 further includes:
if the second protocol stack registration fails, the application processor restores default protocol stack switch states in a plurality of protocol stacks supported by the modem or resets the modem simultaneously.
Optionally, after the application processor records the current location information if the second protocol stack is successfully registered, the method for processing the network communication function exception shown in fig. 1 further includes:
and if the position is changed, the modem restores the default protocol stack switch state in a plurality of protocol stacks supported by the modem or resets the modem simultaneously.
Optionally, the method for processing the network communication function abnormality shown in fig. 1 further includes:
if the protocol stack state abnormity reason is not reported, the application processor acquires the protocol stack state abnormity reason and a log; and the application processor reports the abnormal reason, the current position information and the log to a network side and/or a user.
Optionally, the reporting, by the application processor, the abnormal cause, the current location information, and the log to a network side includes: and the application processor reports the abnormal reason of the protocol stack state, the log and the current position information to network side equipment through a wireless fidelity (WiFi) network.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for handling network communication function abnormality according to a second embodiment of the present invention. As shown in fig. 2, a method for processing a network communication function abnormality according to an embodiment of the present invention may include steps S201 to S212:
s201, whether the modem detects the protocol stack state abnormity.
If yes, go to step S202.
If not, step S201 is executed.
In the embodiment of the invention, the modem is used for converting baseband signals into radio frequency signals, converting the radio frequency signals into the baseband signals, processing signaling of an Access Stratum (AS) and a non-access stratum (NAS), interfacing with an AP processor and the like; the modem supports multiple protocol stacks. The abnormal state of the protocol stack means that a detection result of the current state context does not accord with a pre-expected result in the communication process, for example, when only an uplink data packet is detected within a period of time but no downlink data packet exists, the abnormal state of the protocol stack is considered (namely, an uplink and a downlink are not communicated); or the UE intelligent algorithm judges that the protocol stack is abnormal in operation according to the abnormal state phenomenon; or, the communication process between the UE and the network side device is affected by the uncertain factor, and the UE is out of synchronization; the abnormal reasons of the protocol stack state can be divided into a plurality of types, the same protocol stack state abnormality can be caused by different abnormal reasons, the specific abnormal reason positioning can be determined by any known means, and the invention is not limited.
S202, the modem instructs the application processor to process the exception.
Optionally, the specific implementation manner of the modem instructing the application processor to process the exception is as follows: the modem sends an exception indication message to the application processor, and the application processor receives the exception indication message to indicate that the modem detects the protocol stack state exception, and at the moment, the application processor needs to process the exception. The format of the exception indication message is not limited in the present invention, and may be implemented by using an extension field in an existing message or by constructing a new message.
S203, the application processor closes the first protocol stack causing the protocol stack state exception.
If the modem uses the first protocol stack to generate the protocol stack state exception, in order to prevent the protocol stack state exception from repeatedly generating or further deteriorating, the application processor needs to close the first protocol stack. Optionally, the specific implementation manner of the first protocol stack that causes the protocol stack state exception when the application processor is closed is as follows: the application processor queries a status flag bit indicating a protocol stack in the modem to acquire a first protocol stack currently used (for example, the status flag bit is 1 to indicate that the corresponding protocol stack is in an open state, and the status flag bit is 0 to indicate that the corresponding protocol stack is in a closed state), and the application processor sets the status flag bit of the first protocol stack to 0 to close the first protocol stack.
And S204, the application processor starts a second protocol stack, and performs network registration by using the second protocol stack, wherein the second protocol stack is a protocol stack other than the first protocol stack in a plurality of protocol stacks supported by the modem.
In the embodiment of the present invention, after the first protocol stack is closed, the UE is converted from the connection state to the idle state, the application processor selects the second protocol stack, the second protocol stack is a protocol stack other than the first protocol stack in the plurality of protocol stacks supported by the modem, and the application processor opens the second protocol stack and performs network registration using the second protocol stack. Optionally, a specific implementation manner of the network registration may be: the UE initiates an attach request (attach request) to the network side equipment, if the network side equipment allows the UE to access, an attach response (attach response) is returned to the UE, which indicates that the network registration is successful, and the UE is converted from an idle state to a connection state; and if the network side equipment does not allow the UE to access, returning error information to the UE, which indicates that the network registration fails. Optionally, the policy for the application processor to select the second protocol stack may be: selecting a protocol stack one level lower than the first protocol stack as a second protocol stack; or measuring the signal intensity of cell signals corresponding to each protocol stack supported by the modem, and taking the protocol stack with the maximum signal intensity as a second protocol stack; or selecting a protocol stack one level higher than the first protocol stack as a second protocol stack; alternatively, other strategies may be used to determine the second protocol stack, and the invention is not limited in this respect.
S205, the application processor judges whether the network registration is successful.
If yes, go to step S206.
If not, go to step S207.
S206, the application processor records the current position information. Then, step S209 is executed, and the parallel process of step S208 is started.
Optionally, the location information represents an identity of a pre-planned logical location in the mobile communication network, for example, the location information includes a cell identity or a location area code, etc.
S207, the application processor restores the default protocol stack switch state in a plurality of protocol stacks supported by the modem or the application processor restores the default protocol stack switch state in the plurality of protocol stacks supported by the modem and resets the modem at the same time.
Wherein, the priority of a plurality of protocol stacks supported by the modem is divided into high and low. Optionally, the priority level of each protocol stack supported by the modem may be preset, for example, the priority level of each protocol stack supported by the modem may be set when the modem leaves a factory; or, in the process that the modem is configured in the UE and initialized, the priority level of each protocol stack supported by the modem may be set according to the network connection and the network signal strength when the UE uses each protocol stack; and so on. Optionally, the priority level of each protocol stack supported by the modem may be flexibly adjusted, for example, the priority level may be set according to the network connection and the network signal strength when the UE uses each protocol stack in a certain location area; or, the priority level of each protocol stack may be set according to the sequence of the common network communication system of the UE; and so on. It should be noted that the higher the priority level of a certain protocol stack is, the better network connection or stronger network signal can be obtained by the UE based on the protocol stack. The protocol stack with the highest priority in the modem is generally called a default protocol stack, and the application processor generally uses the protocol stacks to realize network registration and network use of the UE according to the order of priority from high to low.
Because the UE has the characteristics of mobility and platform update, when the UE moves in location or performs platform update, its current attribute changes, and its network connection condition may also change, for example: the UE may make a network connection at location a based on the second protocol stack, however, when the UE moves from location a to location B, the network connection may not be made based on the second protocol stack; similarly, the UE may not be able to connect to the network in location a based on the first protocol stack, but may connect to the network in location B. Therefore, the application processor uses the second protocol stack to unsuccessfully register on the network, and the application processor restores the default protocol stack switch state or the modem restores the default protocol stack switch state according to the default protocol stack switch state and simultaneously performs reset operation on the modem. It is understood that the default protocol stack here may be the first protocol stack or other protocol stacks other than the first protocol stack. It should be noted that, if the default protocol stack in this embodiment is the first protocol stack (i.e. the protocol stack that has been closed and causes the exception to the state of the protocol stack), this step is equivalent to restarting the first protocol stack. Therefore, after the first protocol stack is restarted, the current attribute of the UE is changed, so that the UE can resume the network use based on normal network registration of the restarted first protocol stack.
S208, the application processor detects whether the position information changes.
If yes, go to step S207.
If not, go to step S208.
Optionally, the application processor periodically acquires the location information, and when the currently acquired location information changes compared with the location information acquired last time, step S207 is executed, otherwise, the location information continues to be acquired. For example, the location information is a cell identity, and the UE moves from one cell to another cell to indicate that the location information changes; for another example, the location information is a location area code, and the UE moves from one location area to another location area, indicating that the location information changes. The period of the application processor acquiring the position information is not limited in the present invention, and can be set according to actual requirements.
S209, the application processor judges whether the abnormal reason of the protocol stack state is reported.
If yes, go to step S212.
If not, go to step S210.
Optionally, the reason for the protocol stack state exception may be represented by a reason code, different exception reasons correspond to different reason codes, and the exception reason may be represented by a text description mode.
S210, the application processor acquires the abnormal reason and the log of the protocol stack state.
In the embodiment of the present invention, the log represents operation information of detecting a protocol stack state by a modem, and the operation information includes: operation instruction, operation time and return result.
S211, the application processor reports the abnormal reason, the current position information and the log to a network side and/or a user.
Optionally, the specific implementation of reporting the exception cause, the current location information, and the log to the network side device by the application processor may be: reporting to network side equipment through a wireless fidelity (WiFi) network; or the application processor can also display the abnormal reason on a display screen of the UE for the user to view.
And S212, the application processor processes the exception ending.
It can be seen that, in the embodiment of the present invention, the application processor receives an exception indication message sent by the modem when detecting that the state of the protocol stack is abnormal; the application processor closes a first protocol stack causing protocol stack state exception; the application processor starts a second protocol stack, and uses the second protocol stack to perform network registration, wherein the second protocol stack is a protocol stack except the first protocol stack in a plurality of protocol stacks supported by the modem; and if the second protocol stack is successfully registered, the application processor records the current position information. Therefore, when the modem cannot work normally due to abnormal state of the protocol stack, the modem is recovered to be normal through a network registration mode, the problem of overlong time consumption caused by manual forced restart of a mobile phone or position updating is avoided, and the time for recovering network faults is shortened.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for handling network communication function abnormality according to a third embodiment of the present invention. As shown in fig. 3, a method for processing a network communication function exception according to an embodiment of the present invention may include steps S301 to S310:
s301, whether the application processor detects the protocol stack state abnormity.
If yes, go to step S302.
If not, step S301 is executed.
And S302, the modem instructs the application processor to process the exception.
Optionally, the specific implementation manner of the modem instructing the application processor to process the exception is as follows: the modem sends an exception indication message to the application processor, and the application processor receives the exception indication message to indicate that the modem detects the protocol stack state exception, and at the moment, the application processor needs to process the exception. The format of the exception indication message is not limited in the present invention, and may be implemented by using an extension field in an existing message or by constructing a new message.
S303, the application processor closes the first protocol stack causing the protocol stack state exception.
And S304, the application processor starts a second protocol stack, and performs network registration by using the second protocol stack, wherein the second protocol stack is a protocol stack other than the first protocol stack in a plurality of protocol stacks supported by the modem.
S305, if the network registration is successful, the application processor records the current position information.
S306, the application processor detects whether the position information changes.
If yes, go to step S307.
If not, go to step S306.
S307, the application processor restores the default protocol stack switch state in a plurality of protocol stacks supported by the modem or the application processor restores the default protocol stack switch state in the plurality of protocol stacks supported by the modem and resets the modem at the same time.
S308, the application processor judges whether the abnormal reason of the protocol stack state is reported or not.
Optionally, if the reason for the abnormal state of the protocol stack is reported, step S301 is executed; after the cause of the abnormal state of the protocol stack is reported, the user can adjust or repair the abnormal state according to the cause of the abnormal state, and then the user continues to jump to the step S301 to detect the abnormal state by the modem, and if the abnormal state of the protocol stack is still detected by the modem, the user continues to execute the subsequent steps such as the step S301. Otherwise, step S309 is performed.
S309, the application processor obtains the abnormal reason and the log of the protocol stack state.
S310, the application processor reports the abnormal reason, the current position information and the log to a network side and/or a user.
After the information is reported, the process may also jump to step S301, where the application processor detects an exception, and if the application processor still detects an exception in the state of the protocol stack, the process continues to execute subsequent steps such as step S302.
Through a circulation mode, the problem of protocol stack state abnormity can be solved, after the problem is solved, the application processor can not detect the protocol stack state abnormity any more, and the UE can restore normal work.
It should be noted that, in the embodiment, please refer to the relevant descriptions of steps S201 to S2012 in the method for processing a network communication function abnormality disclosed in the second embodiment of the present invention and the relevant descriptions of steps S101 to S104 in the method for processing a network communication function abnormality disclosed in the first embodiment of the present invention, and no further description is given here.
