Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Please refer to FIG. 1 , which is a schematic flowchart of a first embodiment of a method for handling abnormalities in network communication functions provided by an embodiment of the present invention. The method for handling the abnormality of the network communication function described in this embodiment includes the following steps:

S101. When the modem of the mobile terminal detects that the currently used first protocol stack is abnormal, the modem judges whether the number of abnormalities of the first protocol stack within a preset time period reaches a preset value, and if so, execute step S102.

Wherein, the modem is used to convert the baseband signal into a radio frequency signal, convert the radio frequency signal into a baseband signal, process the signaling of the access layer AS and the non-access layer NAS, and interface with the AP processor, etc. The modem can support multiple protocol stacks, and the protocol stack represents the sum of multiple protocols corresponding to a certain communication standard, for example: the protocol stack includes the GSM protocol stack, the EDGE protocol stack, the HSPDA protocol stack, the TD-SCDMA protocol stack, and the TDD-LTE protocol stack, FDD-LTE protocol stack, etc., each communication standard protocol stack includes multiple sub-protocol stacks, which will not be repeated here.

Among them, the abnormality of the protocol stack refers to the fact that the detection result of the current state context during the communication process does not conform to the expected result. The status is abnormal (that is, the uplink and downlink links are blocked); the intelligent algorithm of the mobile terminal judges that the operation of the protocol stack is abnormal according to the phenomenon of abnormal status, or the communication process between the mobile terminal and the network side is affected by uncertain factors and there is a situation of out-of-synchronization , some state abnormalities are common and easy to handle, and some state abnormalities are rare and difficult to handle. Leaving unhandled state abnormalities that are difficult to handle may lead to further deterioration of protocol stack abnormalities and are difficult to control.

S102. The modem disables the first protocol stack, and selects a second protocol stack other than the first protocol stack from multiple protocol stacks supported by the modem.

Specifically, when the modem detects that the currently used first protocol stack is abnormal, it judges whether the number of abnormalities of the first protocol stack in the preset time period reaches a preset value, and if so, the modem closes the first protocol stack to prevent the first protocol stack A protocol stack exception occurs repeatedly. Then, the modem selects a second protocol stack other than the first protocol stack from a plurality of supported protocol stacks, wherein the strategy selected by the modem may be: select a protocol stack one level lower than the first protocol stack as the second protocol stack Two protocol stacks; or measure the signal strength of the cell signals corresponding to the surrounding protocol stacks, and use the protocol stack with the largest 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 use other strategies to determine the second protocol stack, which is not limited in the present invention.

S103. The modem starts the second protocol stack, and uses the second protocol stack to perform network registration again.

In the specific implementation, after closing the first protocol stack, the mobile terminal is converted from the service state to the non-service state, and the modem turns on the selected second protocol stack, and uses the second protocol stack to perform network registration. For example, the process of LTE network registration is: The terminal initiates an attach request (English: attachrequest) to the network side. If the network side allows the mobile terminal to access, the network side returns an attach response (English: attachaccept) to the mobile terminal, indicating that the network registration is successful, and the mobile terminal changes from the no-service state to There is a service state; if the network side does not allow the mobile terminal to access, the network side returns a rejection/error message to the mobile terminal, indicating that the network registration failed.

S104. When the network registration is successful, the modem records the location information of the mobile terminal.

Wherein, the location information indicates the logical location of the mobile terminal 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 are not limited in this embodiment of the present invention. If the modem successfully registers with the network using the second protocol stack, the modem records the current location information of the mobile terminal.

S105. When the network registration fails, the modem restores the switch state of the default protocol stack in the multiple protocol stacks or the modem restores the switch state of the default protocol stack in the multiple protocol stacks and resets the modem at the same time.

Specifically, the modem fails to register on the network using the second protocol stack, and the modem restores the switch state of the default protocol stack according to the switch state of the default protocol stack known in advance, or the modem restores the switch state of the default protocol stack according to the switch state of the default protocol stack known in advance. , restore the switch state of the default protocol stack and reset the modem at the same time. The default protocol stack is a pre-set protocol stack among the multiple protocol stacks supported by the modem. Here, the same default protocol stack can be set for all regions as the protocol stack initially selected by the modem, or for a single region or Different default protocol stacks are set in multiple areas of a certain area, which is not limited in this embodiment of the present invention. After the reset operation, the modem uses the default protocol stack for network registration. After the network registration is successful, the modem uses the default protocol stack for work.

In the embodiment of the present invention, when the modem of the mobile terminal detects that the currently used first protocol stack is abnormal, the modem judges whether the number of abnormalities of the first protocol stack within the preset duration reaches a preset value, and if so, the modem Close the first protocol stack, and open the second protocol stack other than the first protocol stack among the multiple protocol stacks supported by the modem, and then use the second protocol stack to register with the network, and record the mobile when the network registration is successful The current location information of the terminal. When the network registration fails, the modem restores the switch state of the default protocol stack among the multiple protocol stacks, or resets the modem at the same time. The modem can automatically try to recover by switching other protocol stacks for network registration. Normal, to avoid the time-consuming problem caused by manual forced restart of the mobile terminal or location change, and improve the processing efficiency when the network communication function is abnormal.
