Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic flowchart of a method for processing a network communication function exception according to an embodiment of the present invention is shown, where in the embodiment of the present invention, the method includes:
s101, the modem detects that the position updating fails.
S102, the modem acquires a first protocol stack currently used by the modem.
Specifically, the modem is configured to convert a baseband signal into a radio frequency signal, convert the radio frequency signal into the baseband signal, process signaling of an Access Stratum (AS) and a non-access stratum (NAS), interface with the AP processor, and the like; the modem supports multiple protocol stacks. The UE initiates a LOCATION registration process by sending a LOCATION UPDATE REQUEST message (such as LOCATION UPDATE REQUEST, TRACKING AREA UPDATE REQUEST, etc.), and before a User Equipment (UE) completes LOCATION UPDATE, a failure of LOCATION UPDATE may be caused by an abnormal protocol stack or rejection of LOCATION UPDATE by the network side. The abnormal reasons causing the failure of the location update include: the reason why the RRC radio link establishment fails due to poor signal coverage or large signal interference, the NAS layer receives an error indication of the RRC layer or receives an NAS signaling connection release indication of the RRC layer, the UE enters a new Tracking Area (TA), the RRC layer indicates that the location UPDATE request message transmission fails, the RRC layer indicates that the message transmission fails when the UE transmits a location UPDATE COMPLETE message (TRACKING AREA UPDATE COMPLETE), the UE does not receive a location UPDATE allow message (TRACKING AREA data ACCEPT) sent by the network side before the timer T3430 times out, the UE REJECTs (TRACKING AREA UPDATE REJECT) message for location UPDATE, the cause field in the location UPDATE REJECT (TRACKING AREA UPDATE REJECT) message fails to detect, the location UPDATE procedure conflicts with other procedures, the UE fails to authenticate or fails to activate security, and the like. The reasons why the network side rejects the location update are as follows: illegal ue (illegal me), EPS service not allowed (EPS services not allowed), PLMN not allowed (PLMN not allowed), Tracking area not allowed (Tracking area not allowed), EPS service not allowed, and the like. If the UE cannot initiate the service after cell reselection, the location registration failure can be judged. The protocol stack represents a sum of a plurality of protocols corresponding to a certain communication system, for example: the protocol stacks comprise a GSM protocol stack, an EDGE protocol stack, an HSPDA protocol stack, a TD-SCDMA protocol stack, a TDD-LTE protocol stack, an FDD-LTE protocol stack and the like, and a plurality of sub protocol stacks are arranged below each communication system protocol stack, which is not described again. The modem determines a first protocol stack currently in use when a location update failure is detected.
It should be noted that the modem may be integrated inside the application processor AP or may be a chip independent from the application processor, and the present invention is not limited thereto.
S103, the modem closes the first protocol stack, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem.
Specifically, the first protocol stack is a protocol stack causing a location update failure, and the modem needs to close the first protocol stack to prevent the location update failure from occurring repeatedly. Then, the modem determines a second protocol stack, which is selected from the plurality of protocol stacks supported by the modem, except the first protocol stack, wherein the policy selected by the modem 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 surrounding protocol stack, 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; or other strategies may be used to determine the second protocol stack, and the invention is not limited in this respect.
And S104, the modem starts the second protocol stack and uses the second protocol stack for network registration.
Specifically, after the first protocol stack is closed, the mobile terminal changes to a non-service state, the modem opens the selected second protocol stack, and performs network registration using the second protocol stack, for example, the LTE network registration process is as follows: the mobile terminal initiates an attach request (attach request) to the network side, if the network side allows the mobile terminal to access, an attach response (attach accept) is returned to the mobile terminal, which indicates that the network registration is successful, and the mobile terminal is converted from an idle state to a connection state; and if the network side does not allow the mobile terminal to access, returning error information to the mobile terminal, which indicates that the network registration fails.
And S105, if the network registration is successful, the modem records the current position information.
Specifically, the location information indicates a logical location of the mobile terminal 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 registration of the network using the second protocol stack is successful, the modem records the current location information.
When the embodiment of the invention is implemented, when the modem detects that the position updating fails, the protocol stack currently used by the modem is closed, other protocol stacks except the protocol stack currently used are selected from a plurality of protocol stacks supported by the modem, the other protocol stacks are opened and the other protocol stacks are used for registering the network, and when the network is successfully registered, the current position information is recorded. Therefore, when the modem can not normally communicate, the modem is quickly detected, and the modem automatically tries to recover to normal by a network registration mode through other protocol stacks, so that the problem of overlong time consumption caused by forced restart of a mobile phone or location update is avoided, and the time for recovering network failures is reduced.
Referring to fig. 2, a schematic flowchart of a method for processing a network communication function exception according to an embodiment of the present invention is shown, where in the embodiment of the present invention, the method includes:
s201, the modem detects that the position updating fails.
Specifically, the modem is installed in the handset, and may be packaged in the application processor AP or be independent of the application processor, which is not limited by the present invention. The modem is used to convert baseband signals to radio frequency signals, convert radio frequency signals to baseband signals, process Access Stratum (AS) and non-access stratum (NAS) signaling, interface with an AP processor, and the like. The UE initiates the LOCATION registration procedure by sending a LOCATION UPDATE REQUEST message (e.g., LOCATION UPDATE REQUEST, TRACKING AREA UPDATE REQUEST, etc.), and a failure of the UE LOCATION UPDATE may be caused by either an exception to the protocol stack or a rejection of the LOCATION UPDATE by the network side before the UE completes the LOCATION UPDATE. The abnormal reasons causing the failure of the location update include: the reason why the RRC radio link establishment fails due to poor signal coverage or large signal interference, the NAS layer receives an error indication of the RRC layer or receives an NAS signaling connection release indication of the RRC layer, the UE enters a new Tracking Area (TA), the RRC layer indicates that the location UPDATE request message transmission fails, the RRC layer indicates that the message transmission fails when the UE transmits a location UPDATE COMPLETE message (TRACKING AREA UPDATE COMPLETE), the UE does not receive a location UPDATE allow message (TRACKING AREA data ACCEPT) sent by the network side before the timer T3430 times out, the UE REJECTs (TRACKING AREA UPDATE REJECT) message for location UPDATE, the cause field in the location UPDATE REJECT (TRACKING AREA UPDATE REJECT) message fails to detect, the location UPDATE procedure conflicts with other procedures, the UE fails to authenticate or fails to activate security, and the like. The reasons why the network side rejects the location update are as follows: illegal ue (illegal me), EPS service not allowed (EPS services not allowed), PLMN not allowed (PLMN not allowed), Tracking area not allowed (Tracking area not allowed), EPS service not allowed, and the like. If the UE cannot initiate the service after cell reselection, the location registration failure can be judged. The modem may detect a location update failure.
S202, the modem acquires a first protocol stack currently used by the modem.
Specifically, a protocol stack represents a sum of multiple protocol stacks corresponding to a certain communication system, for example: the protocol stack comprises a GSM protocol stack, an EDGE protocol stack, an HSPDA protocol stack, a TD-SCDMA protocol stack, a TDD-LTE protocol stack, an FDD-LTE protocol stack and the like, and a plurality of sub protocol stacks are arranged below each communication system protocol stack, for example: the TD-LTE protocol stack comprises a physical layer protocol stack, a Medium Access Control (MAC) protocol stack, a Radio Link Control (RLC) protocol stack, an RRC protocol stack, a PDCP protocol stack, an NAS protocol stack and the like. And will not be described in detail herein. The method for the modem to acquire the first protocol stack currently used by the modem may be: inquiring a status flag bit indicating a protocol stack in the modem to acquire a currently used first protocol stack, for example, the flag bit 1 indicates that the corresponding protocol stack is in an open state, and the flag bit 0 indicates that the corresponding protocol stack is in a closed state.
S203, the modem closes the first protocol stack, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem.
Specifically, the modem uses the first protocol stack to cause a location update failure, thereby causing an abnormality of the modem, and the modem needs to close the first protocol stack to prevent the protocol stack registration from being rejected repeatedly. Then, the modem determines a second protocol stack, which is selected from the plurality of protocol stacks supported by the modem, except the first protocol stack, wherein the policy selected by the modem 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 surrounding protocol stack, 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; or other strategies may be used to determine the second protocol stack, and the invention is not limited in this respect.
And S204, the modem starts the second protocol stack and uses the second protocol stack to perform network registration.
Specifically, after the first protocol stack is closed, the mobile terminal changes to a non-service state, the modem opens the selected second protocol stack, and performs network registration using the second protocol stack, for example, the LTE network registration process is as follows: the mobile terminal initiates an attachment request to the network side, if the network side allows the mobile terminal to access, an attachment response is returned to the mobile terminal, which indicates that the network registration is successful, and the mobile terminal is converted from a non-service state to a service state; if the network side does not allow the mobile terminal to access, returning rejection/error information to the mobile terminal, which indicates that the network registration fails.
S205, whether the network registration is successful or not.
Specifically, if the modem successfully registers to the network using the second protocol stack, S206 is performed, and if the modem does not successfully register to the network using the second protocol stack, S207 is performed.
And S206, the modem records the current position information.
Specifically, the location information represents an identifier of a logical location planned in advance in the mobile communication network, for example, the location information includes a cell identifier or a location area code.
S207, the modem restores the switch state of the default protocol stack in the plurality of supported protocol stacks or the modem restores the switch state of the default protocol stack in the plurality of supported protocol stacks and resets the modem at the same time.
Specifically, the modem uses the second protocol stack to unsuccessfully register to the network, and the modem restores the on-off state of the default protocol stack or simultaneously resets the modem according to the on-off state of the default protocol stack known in advance. The default protocol stack is a preset protocol stack in a plurality of protocol stacks supported by the modem, and here, the same default protocol stack may be set for all regions as a protocol stack initially selected for use by the modem, or different default protocol stacks may be set for a single region or a plurality of regions in a certain region, respectively. After the resetting operation is carried out, the modem uses the default protocol stack to carry out network registration, and after the network registration is successful, the modem uses the default protocol stack to work.
And S208, whether the position information is changed or not.
Specifically, the modem periodically acquires the location information, and when the currently acquired location information changes from the last acquired location information, S209 is executed, otherwise S208 is continuously executed. For example, the location information is a cell identifier, and the mobile terminal moves from one cell to another cell to indicate that the location information changes; the position information is a position area code, and the mobile terminal moves from one position area to another position area to indicate that the position information changes. The period of the modem acquiring the location information is not limited in the present invention, and can be set according to actual requirements.
S209, the modem restores the switch state of the default protocol stack in the plurality of supported protocol stacks or the modem restores the switch state of the default protocol stack in the plurality of supported protocol stacks and resets the modem at the same time.
S210, whether the abnormal reason of the position updating failure is reported or not.
Specifically, if the abnormal reason for the location update failure is reported, S213 is executed; otherwise, S211 is executed.
S211, obtaining abnormal reasons and logs of the position updating failure.
S212, reporting the abnormal reason, the current position information and the log to a network side and/or a user.
Specifically, the modem reports the abnormal reason, the current position information and the log to the network side, wherein the information can be reported to the network side through a wifi hot spot under the condition that the mobile terminal is connected with the wifi hot spot, so as to save the flow. Or the modem can also display the abnormal reason on a display screen of the mobile terminal for the user to check.
It should be noted that after S206 is executed, S208 and S210 may be executed in parallel.
And S213, the modem processes the exception and ends.
When the embodiment of the invention is implemented, when the modem detects that the position updating fails, the currently used protocol stack is closed, other protocol stacks except the currently used protocol stack are selected from a plurality of supported protocol stacks, other protocol stacks are opened and other protocol stacks are used for registering the network, when the network is successfully registered, the current position information is recorded, and when the position is changed or the network is failed to be registered, the on-off state of the default protocol stack is recovered or the modem is reset. Therefore, when the modem can not normally communicate, the modem is quickly detected, and the modem automatically restores the normal communication by switching other protocol stacks to carry out network registration, so that the problem of overlong time consumption caused by forced restart of the mobile terminal or location update is avoided, and the time for restoring network failure is reduced.
Referring to fig. 3, another flow diagram of a method for processing a network communication function exception according to an embodiment of the present invention is shown, where in the embodiment of the present invention, the method includes:

The UE initiates a location registration process by sending a location update request message, and before the UE completes location update, the UE location update failure can be caused by protocol stack exception or rejection of the location update at the network side. The abnormal reasons causing the failure of the location update include: the method comprises the following steps that the RRC radio link is failed to establish due to poor signal coverage or large signal interference, the NAS layer receives an error indication of the RRC layer or receives an NAS signaling connection release indication of the RRC layer, the UE enters a new Tracking Area (TA), the RRC layer indicates that the position updating request message is failed to be sent, the RRC layer indicates that the message is failed to be sent when the UE sends a position updating completion message, a position updating permission message sent by the network side is not received before the timer T3430 is overtime, a position updating rejection message, a reason field in the position updating rejection message is failed to detect, a position updating process conflicts with other processes, UE authentication failure or security activation failure and the like. The reasons why the network side rejects the location update are as follows: illegal UE, EPS service not allowed, PLMN not allowed, tracking area not allowed, EPS service not allowed, etc. If the UE cannot initiate the service after cell reselection, the location registration failure can be judged. The modem may detect a location update failure.
S302, the modem acquires a first protocol stack currently used by the modem.
Specifically, a protocol stack represents a sum of multiple protocol stacks corresponding to a certain communication system, for example: the protocol stack comprises a GSM protocol stack, an EDGE protocol stack, an HSPDA protocol stack, a TD-SCDMA protocol stack, a TDD-LTE protocol stack, an FDD-LTE protocol stack and the like, and a plurality of sub protocol stacks are arranged below each communication system protocol stack, for example: the TD-LTE protocol stack comprises a physical layer protocol stack, a Medium Access Control (MAC) protocol stack, a Radio Link Control (RLC) protocol stack, an RRC protocol stack, a PDCP protocol stack, an NAS protocol stack and the like.

Specifically, the modem uses the first protocol stack to cause a location update failure, thereby causing an abnormality of the modem, and the modem needs to close the first protocol stack to prevent the protocol stack registration from being rejected repeatedly. Then, the modem determines a second protocol stack, which is selected from the plurality of protocol stacks supported by the modem, except the first protocol stack, wherein the policy selected by the modem 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 surrounding protocol stack, 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; or other strategies may be used to determine the second protocol stack, and the invention is not limited in this respect.
S304, the modem starts the second protocol stack and uses the second protocol stack to perform network registration.
Specifically, after the first protocol stack is closed, the mobile terminal changes to a non-service state, the modem opens the selected second protocol stack, and performs network registration using the second protocol stack, for example, the LTE network registration process is as follows: the mobile terminal initiates an attachment request to the network side, if the network side allows the mobile terminal to access, an attachment response is returned to the mobile terminal, which indicates that the network registration is successful, and the mobile terminal is converted from a non-service state to a service state; if the network side does not allow the mobile terminal to access, returning rejection/error information to the mobile terminal, which indicates that the network registration fails.
S305, if the network registration is successful, the modem records the current position information. Then step S306 may be performed; step S308 may also be performed in parallel.
Specifically, the location information represents an identifier of a logical location planned in advance in the mobile communication network, for example, the location information includes a cell identifier or a location area code.
And S306, whether the position information changes or not.
Specifically, the modem periodically acquires the location information, and when the currently acquired location information changes from the location information acquired last time, S307 is executed, otherwise S306 is continuously executed. For example, the location information is a cell identifier, and the mobile terminal moves from one cell to another cell to indicate that the location information changes; the position information is a position area code, and the mobile terminal moves from one position area to another position area to indicate that the position information changes. The period of the modem acquiring the location information is not limited in the present invention, and can be set according to actual requirements.

And S308, whether the abnormal reason of the position updating failure is reported or not.
Specifically, if the abnormal reason of the location update failure is reported, S301 is executed; after the abnormal reason of the location update failure is reported, the user can adjust or repair according to the abnormal reason, and then continue to jump to S301 to detect the abnormality by the modem, and if the modem still detects the location update failure, continue to execute the subsequent steps of S302 and the like. Otherwise, S309 is executed.
S309, obtaining abnormal reasons and logs of the position updating failure.

Specifically, the modem reports the abnormal reason, the current position information and the log to the network side, wherein the information can be reported to the network side through a wifi hot spot under the condition that the mobile terminal is connected with the wifi hot spot, so as to save the flow. Or the modem can also display the abnormal reason on a display screen of the mobile terminal for the user to check.
After the information is reported, the process may also jump to step S301, where the modem detects the abnormality, and if the modem still detects the location update failure, the process continues to execute the subsequent steps such as step S302.
Through a circulation mode, the problem of location updating failure can be solved, when the problem is solved, the modem can not detect the location updating failure any more, and the terminal can restore normal work.
