Referring to FIG. 1 , FIG. 1 is a flowchart of a first embodiment of a method for processing an abnormal network communication function according to an embodiment of the present invention. Wherein, as shown in FIG. 1 , a method for processing an abnormal network communication function provided by an embodiment of the present invention may include steps S101 to S104:

S101. The application processor receives an exception indication message sent by the modem after detecting that the protocol stack state is abnormal.

In the embodiment of the present invention, the above-mentioned application processor is called a multimedia application processor (Multimedia Application Processor for short, MAP for short), which is an ultra-large-scale integrated circuit used to expand audio and video functions and dedicated interfaces on the basis of a low-power CPU, and is a smart phone. The important components in the application processor and the baseband processor are generally two independent chips. The above-mentioned modems are used to convert baseband signals into radio frequency signals, convert radio frequency signals into baseband signals, process signaling of the access stratum (AS) and non-access stratum (NAS), and interface with the AP processor. Supports multiple protocol stacks. The abnormal status of the protocol stack means that the detection results of the current status context during the communication process do not match the expected results. For example, when only upstream data packets and no downstream data packets are detected for a period of time, it is considered The protocol stack state is abnormal (that is, the uplink and downlink are blocked); or, the user terminal (User Equipment, UE for short) intelligent algorithm judges that the protocol stack operation is abnormal according to the abnormal state phenomenon; or, the communication process between the UE and the network side device Loss of synchronization due to uncertainty; etc. When the modem detects an abnormal state of the protocol stack, the modem will crash and cannot process data normally, resulting in the UE not being able to access the Internet. The protocol stack represents the sum of multiple protocols corresponding to a certain communication standard. Optionally, the protocol stack includes a Global System for Mobile Communication (GSM) protocol stack, an Enhanced Data Rate for GSM Evolution (EDGE) protocol stack, a High Speed Downlink Packet Access (High Speed Downlink Packet Access) HSPDA) protocol stack, Time Division-Synchronous CodeDivision Multiple Access (TD-SCDMA) protocol stack, Time Division Long Term Evolution (TDD-LTE) protocol stack, Frequency Division Duplex Long Term Evolution (Frequency Division Dual Long TermEvolution, FDD-LTE) protocol stack, etc., each communication standard protocol stack includes multiple sub-protocol stacks, which will not be repeated here. When the modem detects a memory access error, it determines the currently used first protocol stack.

It should be noted that the modem may be integrated inside the application processor, or may be a chip independent of the application processor, which is not limited in the present invention.

S102. The application processor closes the first protocol stack that causes the abnormal state of the protocol stack.

In the embodiments of the present invention, some protocol stack status exceptions are common and easy to handle, and some protocol stack status exceptions are rare and difficult to handle, and leaving unhandled protocol stack status exceptions may lead to protocol stack errors further deterioration and uncontrollable. In order to prevent the abnormality of the protocol stack state from recurring or further deterioration, the application processor needs to close the first protocol stack which causes the abnormality of the protocol stack state.

S103. The application processor starts a second protocol stack, and uses the second protocol stack to perform network registration, where the second protocol stack is other than the first protocol stack among multiple protocol stacks supported by the modem the protocol stack.

In this embodiment of the present invention, after the first protocol stack is closed, the UE is converted from a connected state to an idle state, and the application processor selects a second protocol stack, which is the second protocol stack except the one among the multiple protocol stacks supported by the modem. For protocol stacks other than the first protocol stack, the application processor enables the second protocol stack and uses the second protocol stack to perform network registration. Optionally, the specific implementation manner of the network registration may be: the UE initiates an attach request (attache request) to the network side device, and if the network side device allows the UE to access, returns an attach response (attach response) to the UE, indicating that the network registration is successful, The UE transitions from the idle state to the connected state; if the network side device does not allow the UE to access, it returns an error message to the UE, indicating that the network registration fails. Optionally, the strategy for the application processor to select the second protocol stack may be: selecting a protocol stack that is one level lower than the first protocol stack as the second protocol stack; or, measuring the signal of the cell signal corresponding to each protocol stack supported by the modem strength, and use the protocol stack with the highest signal strength as the second protocol stack; or, select a protocol stack one level higher than the first protocol stack as the second protocol stack; or, adopt other strategies to determine the second protocol stack, the present invention No restrictions apply.

S104. If the registration of the second protocol stack is successful, the application processor records the current location information.

Optionally, the location information represents the logical location of the UE in the mobile communication network, and the location information may be a cell identifier, an area location code, or a location tracking area, etc., which is not limited in the present invention. If the registration of the network using the second protocol stack is successful, the application processor records the current location information.

It can be seen that, in this embodiment of the present invention, the application processor receives an exception indication message sent by the modem after detecting that the protocol stack state is abnormal; the application processor closes the first protocol stack that causes the protocol stack state abnormality; the application processor Open a second protocol stack, and use the second protocol stack for network registration, where the second protocol stack is a protocol stack other than the first protocol stack among the multiple protocol stacks supported by the modem; if the The registration of the second protocol stack is successful, and the application processor records the current location information. In this way, when the modem cannot communicate normally due to the abnormal state of the protocol stack, it is quickly detected, and the modem can automatically restore the normal communication by switching other protocol stacks for network registration, avoiding the consumption caused by manually restarting the mobile phone or updating the location. The problem of excessive time reduces the time for network failure recovery.

Optionally, the method for processing an abnormal network communication function shown in FIG. 1 further includes:

If the registration of the second protocol stack fails, the application processor restores the default protocol stack switch state among the plurality of protocol stacks supported by the modem or resets the modem at the same time.

Optionally, if the registration of the second protocol stack is successful, after the application processor records the current location information, the method for processing an abnormal network communication function shown in FIG. 1 further includes:

If the location changes, the modem restores the default protocol stack switch state among the plurality of protocol stacks supported by the modem or resets the modem simultaneously.

Optionally, the method for processing an abnormal network communication function shown in FIG. 1 further includes:

If the abnormal cause of the protocol stack state is not reported, the application processor obtains the abnormal cause and log of the protocol stack state; the application processor reports the abnormal cause, the current location information and the log to the network side and/or or user.

Optionally, the application processor reports the abnormal cause, the current location information, and the log to the network side, including: the application processor reporting the abnormal state of the protocol stack to the network side device through the Wireless Fidelity WiFi network. Reason, log and the current location information.

Referring to FIG. 2, FIG. 2 is a flowchart of a second embodiment of a method for processing an abnormal network communication function according to an embodiment of the present invention. Wherein, as shown in FIG. 2 , a method for processing an abnormal network communication function provided by an embodiment of the present invention may include steps S201 to S212:

S201. Whether the modem detects that the protocol stack state is abnormal.

If yes, step S202 is executed.

If not, step S201 is executed.

In this embodiment of the present invention, the modem is configured to convert baseband signals into radio frequency signals, convert radio frequency signals into baseband signals, process signaling of the access stratum (AS) and non-access stratum (NAS), and communicate with the AP processor interface, etc.; the modem supports multiple protocol stacks. The abnormal status of the protocol stack means that the detection results of the current status context during the communication process do not match the expected results. For example, when only upstream data packets are detected for a period of time, but there are no downstream data packets, it is considered that the protocol stack The status is abnormal (that is, the uplink and downlink are blocked); or, the UE intelligent algorithm judges that the protocol stack is running abnormally according to the abnormal status; or, the communication process between the UE and the network side device is affected by uncertain factors and the synchronization occurs The reasons for the abnormal state of the protocol stack can be divided into multiple types, the same abnormal state of the protocol stack may be caused by different abnormal causes, and the location of the specific abnormal cause can be determined by any known means, which is not limited in the present invention.

S202. The modem instructs the application processor to handle this exception.

Optionally, the specific implementation manner of the modem instructing the application processor to handle this abnormality is as follows: the modem sends an abnormality indication message to the application processor, and the application processor receives the abnormality indication message indicating that the modem detects that the protocol stack state is abnormal, and at this time, the application processes the abnormality. The device needs to handle the exception. The format of the exception indication message is not limited in the present invention, and can be realized by using the method of extending fields in the existing message or constructing a new message.

S203. The application processor shuts down the first protocol stack that causes the abnormal state of the protocol stack.

If a protocol stack state abnormality occurs when the modem uses the first protocol stack, in order to prevent the protocol stack state abnormality from recurring or further deteriorating, the application processor needs to close the first protocol stack. Optionally, the application processor closes the first protocol stack that causes the abnormal state of the protocol stack. If it is 1, it means that the corresponding protocol stack is in an open state, and if the status flag is 0, it means that the corresponding protocol stack is in a closed state).

S204. The application processor starts a second protocol stack, and uses the second protocol stack to perform network registration, where the second protocol stack is a plurality of protocol stacks supported by the modem except the first protocol stack the protocol stack.

In this embodiment of the present invention, after the first protocol stack is closed, the UE is converted from a connected state to an idle state, and the application processor selects a second protocol stack, which is the second protocol stack except the one among the multiple protocol stacks supported by the modem. For protocol stacks other than the first protocol stack, the application processor enables the second protocol stack and uses the second protocol stack to perform network registration. Optionally, the specific implementation manner of the network registration may be: the UE initiates an attach request (attache request) to the network side device, and if the network side device allows the UE to access, returns an attach response (attach response) to the UE, indicating that the network registration is successful, The UE transitions from the idle state to the connected state; if the network side device does not allow the UE to access, it returns an error message to the UE, indicating that the network registration fails. Optionally, the strategy for the application processor to select the second protocol stack may be: selecting a protocol stack that is one level lower than the first protocol stack as the second protocol stack; or, measuring the signal of the cell signal corresponding to each protocol stack supported by the modem strength, and use the protocol stack with the highest signal strength as the second protocol stack; or, select a protocol stack one level higher than the first protocol stack as the second protocol stack; or, adopt other strategies to determine the second protocol stack, the present invention No restrictions apply.

S205. The application processor determines whether the network registration is successful.

If yes, step S206 is executed.

If not, step S207 is executed.

S206. The application processor records the current location information. Then step S209 is executed, and the parallel process of step S208 is started.

Optionally, the location information represents an identifier of a pre-planned logical location in the mobile communication network, for example, the location information includes a cell identifier or a location area code.

S207. The application processor restores the default protocol stack switch states in the multiple protocol stacks supported by the modem or the application processor restores the default protocol stack switch states in the supported multiple protocol stacks and simultaneously resets all the described modem.

Among them, the multiple protocol stacks supported by the modem have different priority levels. Optionally, the priority levels of each protocol stack supported by the modem may be preset, for example, the priority levels of each protocol stack supported by the modem may be set when the modem is shipped from the factory; or, the modem may be configured in the UE. And in the process of initialization, the priority of each protocol stack supported by the modem is 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 can be flexibly adjusted, for example, the priority level can be set according to the network connection and network signal strength when the UE uses each protocol stack in a certain location area; The priority of each protocol stack is set according to the order of the common network communication system of the UE; and so on. It should be noted that, the higher the priority of a certain protocol stack, the better network connection or stronger network signal the UE can obtain based on the protocol stack. The protocol stack with the highest priority in the modem is usually referred to as the default protocol stack, and the application processor usually uses each protocol stack in order of priority from high to low to implement network registration and network use of the UE.

Due to the characteristics of mobility and platform update of the UE, when the UE moves its location or performs a platform update, its current attributes will change, and its network connection may also change. Network connection can be performed, but when the UE moves from location A to location B, it may not be able to perform network connection based on the second protocol stack; similarly, the UE may not be able to perform network connection in location A based on the first protocol stack, but in location B network connection is available. Therefore, if the application processor fails to register on the network using the second protocol stack, the application processor restores the default protocol stack switch state or the modem restores the default protocol stack switch state according to the switch state of the default protocol stack and simultaneously resets the modem. It can be understood that the default protocol stack here may be either 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 (that is, the protocol stack that has been turned off and caused the abnormal state of the protocol stack), then this step is equivalent to reopening the first protocol stack. Therefore, after restarting the first protocol stack in this step, since the current attribute of the UE has changed, this enables the UE to perform normal network registration based on the restarted first protocol stack and restore network usage.

S208. The application processor detects whether the location information changes.

If yes, step S207 is executed.

If not, step S208 is executed.

Optionally, the application processor periodically acquires the location information, and when the currently acquired location information changes compared with the last acquired location information, step S207 is performed, otherwise, the location information continues to be acquired. For example, if the location information is a cell identifier, and the UE moves from one cell to another, it indicates that the location information has changed; for another example, the location information is the location area code, and the UE moves from one location area to another location area, indicating that the location information has occurred. Variety. The cycle for the application processor to obtain the location information is not limited in the present invention, and can be set according to actual needs.

S209. The application processor determines whether the abnormal cause of the protocol stack state has been reported.

If yes, step S212 is executed.

If not, step S210 is executed.

Optionally, the abnormal cause of the protocol stack state may be represented by a reason code, different abnormal causes correspond to different reason codes, and the abnormal cause may be represented by a text description.

S210. The application processor acquires the abnormal cause and log of the protocol stack state.

In this embodiment of the present invention, the log represents operation information of the modem detecting the state of the protocol stack, and the operation information includes: an operation instruction, an operation time, and a returned result.

S211. The application processor reports the abnormal cause, the current location information and the log to the network side and/or the user.

Optionally, the specific implementation manner in which the application processor reports the abnormal cause, the current location information and the log to the network-side device may be: reporting to the network-side device through the Wi-Fi network; or the application processor may also report the abnormal cause. It is displayed on the display screen of the UE for the user to view.

S212, the application processor processing this abnormal end.

It can be seen that, in this embodiment of the present invention, the application processor receives an exception indication message sent by the modem after detecting that the protocol stack state is abnormal; the application processor closes the first protocol stack that causes the protocol stack state abnormality; the application processor Open a second protocol stack, and use the second protocol stack for network registration, where the second protocol stack is a protocol stack other than the first protocol stack among the multiple protocol stacks supported by the modem; if the The registration of the second protocol stack is successful, and the application processor records the current location information. In this way, when the modem cannot work normally due to the abnormal state of the protocol stack, the modem can be restored to normal by means of network registration, avoiding the problem of excessive time-consuming caused by manually restarting the mobile phone or updating the location, and reducing the time for network failure recovery.

Wherein, as shown in FIG. 3, a method for processing an abnormal network communication function provided by an embodiment of the present invention may include steps S301-S310:

S301. Whether the application processor detects that the protocol stack state is abnormal.

If yes, step S302 is executed.

If not, step S301 is executed.

S302, the modem instructs the application processor to handle this exception.

Optionally, the specific implementation manner of the modem instructing the application processor to handle this abnormality is as follows: the modem sends an abnormality indication message to the application processor, and the application processor receives the abnormality indication message indicating that the modem detects that the protocol stack state is abnormal, and at this time, the application processes the abnormality. The device needs to handle the exception. The format of the exception indication message is not limited in the present invention, and can be realized by using the method of extending fields in the existing message or constructing a new message.

S303. The application processor closes the first protocol stack that causes the abnormal state of the protocol stack.

S304. The application processor starts a second protocol stack, and uses the second protocol stack to perform network registration, where the second protocol stack is a plurality of protocol stacks supported by the modem except the first protocol stack the protocol stack.

S305. If the network registration is successful, the application processor records the current location information.

S307. The application processor restores the default protocol stack switch states in the multiple protocol stacks supported by the modem, or the application processor restores the default protocol stack switch states in the supported multiple protocol stacks and resets all the supported protocol stacks at the same time. described modem.

S308. The application processor determines whether the abnormal cause of the protocol stack state has been reported.

Optionally, if the cause of the abnormality of the protocol stack state has been reported, step S301 is performed; after the cause of the abnormality of the protocol stack state has been reported, the user can adjust or repair according to the abnormal cause, and then continue to jump to step S301 to detect the abnormality by the modem. , if the modem still detects that the state of the protocol stack is abnormal, it continues to perform the subsequent steps such as step S301. Otherwise, step S309 is executed.

S309. The application processor acquires the abnormal reason and log of the protocol stack state.

S310. The application processor reports the abnormal cause, the current location information and the log to the network side and/or the user.

After the above information is reported, it can also jump to step S301, and the application processor detects the abnormality. If the application processor still detects that the protocol stack state is abnormal, the subsequent steps such as S302 are continued.

In a circular manner, the solution of the abnormal state of the protocol stack can be ensured. After the problem is solved, the application processor will no longer detect the abnormal state of the protocol stack, and the UE can resume normal work.
