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.
The embodiment of the invention discloses a processing method of network communication function abnormity and an application processor, which can rapidly solve the problem of network communication function abnormity. The following are detailed below.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for processing network communication function abnormality according to an embodiment of the present invention. As shown in fig. 1, the method for processing network communication function abnormality may include the following steps.
S101, when receiving an abnormal indication message sent by a modem in the mobile terminal, an application processor in the mobile terminal detects whether a common module in the modem is abnormal.
In the embodiment of the present invention, the Application Processor is fully referred to as MAP (Multimedia Application Processor, MAP for short), and is a very large scale integrated circuit for extending audio and video functions and dedicated interfaces on the basis of a low power consumption CPU, and is an important component in a mobile terminal (such as a smart phone, a palm computer, a notebook computer, etc.), and the Application Processor and the baseband Processor are generally two independent chips. A Modem (Modem) is located in a mobile terminal (e.g., a smart phone, a palm pc, a notebook computer, etc.), and the Modem is used to convert a baseband signal into a radio frequency signal, convert a radio frequency signal into a baseband signal, process signaling of an Access Stratum (AS) and a non-access stratum (NAS), interface with an AP processor, and the like. The modem includes a common module for configuring configuration parameters in the modem and a protocol stack. The protocol stack represents a sum of a plurality of protocols corresponding to a certain communication system, for example: 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 Duplex Long Term Evolution (TDD-LTE) protocol stack, a Frequency Division Duplex Long Term Evolution (FDD) protocol stack, and the like, and a plurality of sub-stack protocols are further included below each Communication System protocol stack, which is not repeated here.
In the embodiment of the invention, the modem abnormity can comprise protocol stack abnormity and public module abnormity, and when the modem is abnormal, the modem cannot normally process data, so that a user cannot surf the internet.
In the embodiment of the present invention, the abnormality indication message is used to indicate that the modem is abnormal. When the application processor receives an abnormality indication message transmitted from the modem, the application processor detects whether a common module in the modem is abnormal. If the application processor detects an anomaly in the common module within the modem, the application processor optionally restarts the modem to resolve the anomaly in the common module. If the application processor detects that the common module in the modem is normal, it indicates that the cause of the abnormality of the modem is abnormal in the protocol stack, and step S102 is executed.
S102, the application processor closes a first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem.
In the embodiment of the invention, when a public module in the modem is normal, the application processor determines that a protocol stack in the modem is abnormal, and the first protocol stack is a protocol stack causing the abnormality of the modem. The application processor needs to shut down the first protocol stack to prevent the first protocol stack from continuing to cause an exception to the modem, and selects a second protocol stack, other than the first protocol stack, from a plurality of protocol stacks supported by the modem. 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 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.
S103, the application processor starts a second protocol stack and performs network registration again by using the second protocol stack.
In the embodiment of the present invention, specifically, after the application processor closes the first protocol stack, the mobile terminal is converted from the connection state to the idle state, and the application processor opens the selected second protocol stack and performs network registration using the second protocol stack. The network registration process comprises the following steps: 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 response) 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 S104, when the network registration is successful, the application processor records the current position information of the mobile terminal.
In this embodiment of the present invention, 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 Identity (CID), a Location Area Code (LAC), a Location tracking Area, or the like. And if the application processor successfully registers the network by using the second protocol stack, the application processor records the current position information of the mobile terminal.
In this embodiment of the present invention, optionally, when the network registration fails, the application processor recovers the switch state of a default protocol stack in the plurality of protocol stacks supported by the modem or recovers the switch state of a default protocol stack in the plurality of protocol stacks supported by the modem, and resets the modem. Specifically, the default protocol stack is a preset protocol stack, and the default protocol stack is one of a plurality of protocol stacks supported by the modem. 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 multiple regions in a certain area, respectively. If the second protocol stack fails to register the network, the application processor starts a preset default protocol stack and resets the modem, and after the reset operation, the modem works by using the default protocol stack.
In the method depicted in fig. 1, upon receiving an abnormality indication message transmitted from a modem in a mobile terminal, an application processor in the mobile terminal detects whether a common module in the modem is abnormal; if the public module in the modem is normal, the application processor closes a first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem; the application processor starts a second protocol stack and uses the second protocol stack to perform network registration again; and when the network registration is successful, the application processor records the current position information of the mobile terminal. Therefore, by implementing the embodiment of the invention, when the modem is abnormal, the application processor can quickly restore the modem to be normal by switching other protocol stacks to carry out network registration, thereby quickly solving the problem of abnormal network communication function.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another method for handling network communication function abnormality according to an embodiment of the present invention. As shown in fig. 2, the method for processing network communication function abnormality may include the following steps.
S201, when receiving an abnormal indication message sent by a modem in the mobile terminal, an application processor in the mobile terminal detects whether a common module in the modem is abnormal.
In the embodiment of the invention, the modem abnormity can comprise protocol stack abnormity and public module abnormity, and when the modem is abnormal, the modem cannot normally process data, so that a user cannot surf the internet.
In the embodiment of the present invention, the abnormality indication message is used to indicate that the modem is abnormal. When the application processor receives an abnormality indication message transmitted from the modem, the application processor detects whether a common module in the modem is abnormal. If the application processor detects an anomaly in the common module within the modem, the application processor optionally restarts the modem to resolve the anomaly in the common module. If the application processor detects that the common module in the modem is normal, it indicates that the abnormality of the modem is due to the abnormal protocol stack, and then step S202 is executed.
S202, the application processor closes a first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem.
In the embodiment of the invention, when a public module in the modem is normal, the application processor determines that a protocol stack in the modem is abnormal, and the first protocol stack is a protocol stack causing the abnormality of the modem. The application processor needs to shut down the first protocol stack to prevent the first protocol stack from continuing to cause an exception to the modem, and selects a second protocol stack, other than the first protocol stack, from a plurality of protocol stacks supported by the modem. 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 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.
S203, the application processor starts a second protocol stack and uses the second protocol stack to perform network registration again.
In the embodiment of the present invention, specifically, after the application processor closes the first protocol stack, the mobile terminal is converted from the connection state to the idle state, and the application processor opens the selected second protocol stack and performs network registration using the second protocol stack. The network registration process comprises the following steps: 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 response) 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 S204, when the network registration is successful, the application processor records the current position information of the mobile terminal.
In this embodiment of the present invention, 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 Identity (CID), a Location Area Code (LAC), a Location tracking Area, or the like. And if the application processor successfully registers the network by using the second protocol stack, the application processor records the current position information of the mobile terminal.
S205, the application processor detects whether the position information of the mobile terminal is changed.
Specifically, after recording the current position information of the mobile terminal, the application processor periodically acquires the position information of the mobile terminal and compares the periodically acquired position information with the recorded position information; when the periodically acquired position information changes compared with the recorded position information, step S206 is executed, otherwise, the position information continues to be acquired. 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 application processor acquiring the position information is not limited in the present invention, and can be set according to actual requirements.
S206, the application processor recovers the switch state of the default protocol stack in the plurality of protocol stacks supported by the modem or recovers the switch state of the default protocol stack in the plurality of protocol stacks supported by the modem and simultaneously resets the modem.
In the embodiment of the invention, when the position information acquired periodically changes compared with the recorded position information, the application processor restores the default protocol stack switch state or restores the default protocol stack switch state according to the known default protocol stack switch state in advance and simultaneously resets the modem. The default protocol stack is a preset protocol stack in a plurality of protocol stacks supported by the modem. 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 multiple regions in a certain area, respectively. After the reset operation is carried out, the application processor uses the default protocol stack to carry out network registration, and after the network registration is successful, the application processor uses the default protocol stack to work.
In the method depicted in fig. 2, upon receiving an abnormality indication message transmitted from a modem in a mobile terminal, an application processor in the mobile terminal detects whether a common module in the modem is abnormal; if the public module in the modem is normal, the application processor closes a first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem; the application processor starts a second protocol stack and uses the second protocol stack to perform network registration again; and when the network registration is successful, the application processor records the current position information of the mobile terminal. Therefore, by implementing the embodiment of the invention, when the modem is abnormal, the application processor can quickly restore the modem to be normal by switching other protocol stacks to carry out network registration, thereby quickly solving the problem of abnormal network communication function.
Referring to fig. 3, fig. 3 is a flowchart illustrating another method for handling network communication function abnormality according to an embodiment of the present invention. As shown in fig. 3, the method for processing network communication function abnormality may include the following steps.
S301, when receiving an abnormal indication message sent by a modem in the mobile terminal, an application processor in the mobile terminal detects whether a common module in the modem is abnormal.
In the embodiment of the invention, the modem abnormity can comprise protocol stack abnormity and public module abnormity, and when the modem is abnormal, the modem cannot normally process data, so that a user cannot surf the internet.
In the embodiment of the present invention, the abnormality indication message is used to indicate that the modem is abnormal. When the application processor receives an abnormality indication message transmitted from the modem, the application processor detects whether a common module in the modem is abnormal. If the application processor detects an anomaly in the common module within the modem, the application processor optionally restarts the modem to resolve the anomaly in the common module. If the application processor detects that the common module in the modem is normal, it indicates that the abnormality of the modem is due to the abnormal protocol stack, and then step S302 is executed.
S302, the application processor closes the first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem.
In the embodiment of the invention, when a public module in the modem is normal, the application processor determines that a protocol stack in the modem is abnormal, and the first protocol stack is a protocol stack causing the abnormality of the modem. The application processor needs to shut down the first protocol stack to prevent the first protocol stack from continuing to cause an exception to the modem, and selects a second protocol stack, other than the first protocol stack, from a plurality of protocol stacks supported by the modem. 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 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 S303, the application processor starts a second protocol stack and performs network registration again by using the second protocol stack.
In the embodiment of the present invention, specifically, after the application processor closes the first protocol stack, the mobile terminal is converted from the connection state to the idle state, and the application processor opens the selected second protocol stack and performs network registration using the second protocol stack. The network registration process comprises the following steps: 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 response) 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.
S304, when the network registration is successful, the application processor records the current position information of the mobile terminal.
In this embodiment of the present invention, 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 Identity (CID), a Location Area Code (LAC), a Location tracking Area, or the like. And if the application processor successfully registers the network by using the second protocol stack, the application processor records the current position information of the mobile terminal.
S305, the application processor sets the first protocol stack exception as the exception reason of the modem and records the exception reason.
In the embodiment of the invention, after the application processor detects that the public module in the modem is normal, the application processor sets the first protocol stack exception as the exception reason of the modem and records the exception reason.
S306, the application processor judges whether the abnormal reason is reported.
Specifically, the abnormal reason of the first protocol stack abnormality may be represented by a reason code, different abnormal reasons correspond to different reason codes, and the abnormal reason may be represented by a text description mode, and if the abnormal reason of the first protocol stack abnormality is not reported, S307 is executed.
And S307, the application processor reports the recorded abnormal reason, the position information of the mobile terminal and the log information to the network side and/or displays the abnormal reason.
In the embodiment of the invention, if the application processor judges that the abnormal reason of the first protocol stack abnormality is not reported, the application processor reports the recorded abnormal reason, the position information of the mobile terminal and the log information to the network side so that an engineer can make an abnormality solution according to the reported information. Specifically, the application processor can report the information to the network side through the wifi hotspot under the condition that the mobile terminal is connected with the wifi hotspot, so as to save the flow. Or the application processor can also display the abnormal reason on a display screen of the mobile terminal for the user to check.
In the method depicted in fig. 3, upon receiving an abnormality indication message transmitted from a modem in the mobile terminal, an application processor in the mobile terminal detects whether a common module in the modem is abnormal; if the public module in the modem is normal, the application processor closes a first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem; the application processor starts a second protocol stack and uses the second protocol stack to perform network registration again; and when the network registration is successful, the application processor records the current position information of the mobile terminal. Therefore, by implementing the embodiment of the invention, when the modem is abnormal, the application processor can quickly restore the modem to be normal by switching other protocol stacks to carry out network registration, thereby quickly solving the problem of abnormal network communication function.

If the detecting module 401 detects that the common module in the modem is normal, which indicates that the cause of the abnormality of the modem is that the protocol stack is abnormal, the closing module 402 closes the first protocol stack currently used by the modem, and selects a second protocol stack other than the first protocol stack from the plurality of protocol stacks supported by the modem. The policy for the shutdown module 402 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 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.
A closing module 402, configured to close a first protocol stack currently used by the modem when the detection module 401 detects that a common module in the modem is normal, and select a second protocol stack, other than the first protocol stack, from multiple protocol stacks supported by the modem.
In the embodiment of the invention, when the public module in the modem is normal, the protocol stack abnormality in the modem is indicated, and the first protocol stack is the protocol stack causing the modem abnormality. The shutdown module 402 shuts down the first protocol stack to prevent the first protocol stack from continuing to cause an exception to the modem, and the shutdown module 402 selects a second protocol stack, other than the first protocol stack, from a plurality of protocol stacks supported by the modem.
And an opening module 403, configured to open the second protocol stack, and perform network registration again using the second protocol stack.
In this embodiment of the present invention, specifically, after the closing module 402 closes the first protocol stack, the mobile terminal is converted from the connection state to the idle state, and the opening module 403 opens the selected second protocol stack, and performs network registration using the second protocol stack. The network registration process comprises the following steps: 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 response) 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.
A recording module 404, configured to record current location information of the mobile terminal when the network registration is successful.
In this embodiment of the present invention, 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 Identity (CID), a Location Area Code (LAC), a Location tracking Area, or the like. If the starting module 403 successfully registers the network using the second protocol stack, the recording module 404 records the current location information of the mobile terminal.
In this embodiment of the present invention, optionally, when the network registration fails, the application processor recovers the switch state of a default protocol stack in the plurality of protocol stacks supported by the modem or recovers the switch state of a default protocol stack in the plurality of protocol stacks supported by the modem, and resets the modem. Specifically, the default protocol stack is a preset protocol stack, and the default protocol stack is one of a plurality of protocol stacks supported by the modem. 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 multiple regions in a certain area, respectively. If the second protocol stack fails to register the network, the application processor starts a preset default protocol stack and resets the modem, and after the reset operation, the modem works by using the default protocol stack.

Wherein:
the detecting module 401 is further configured to detect whether the location information of the mobile terminal changes after the recording module records the current location information of the mobile terminal.
Specifically, after the recording module 404 records the current location information of the mobile terminal, the detecting module 401 periodically acquires the location information of the mobile terminal and compares the periodically acquired location information with the recorded location information; when the periodically acquired location information changes compared to the recorded location information, the recovery module 405 acquires an initial switching state corresponding to each of a plurality of protocol stacks supported by the modem before the modem is abnormal, and adjusts a current switching state corresponding to each of the plurality of protocol stacks to the initial switching state, otherwise, the detection module 401 continues to acquire the location information. 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 detection module 401 acquiring the position information is not limited in the present invention, and may be set according to actual requirements.

In this embodiment of the present invention, the recovery module 405 recovers the default protocol stack switch state or recovers the default protocol stack switch state according to a known default protocol stack switch state in advance, and simultaneously resets the modem. The default protocol stack is a preset protocol stack in a plurality of protocol stacks supported by the modem. 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 multiple regions in a certain area, respectively. After the reset operation is carried out, the application processor uses the default protocol stack to carry out network registration, and after the network registration is successful, the application processor uses the default protocol stack to work.

The determining module 406 is configured to determine whether the abnormal reason recorded by the recording module 404 is reported.
A reporting module 407, configured to report the recorded abnormal reason, the location information of the mobile terminal, and the log information to the network side and/or display the abnormal reason when the determining module 406 determines that the abnormal reason is not reported.
In the embodiment of the present invention, specifically, the reporting module 407 may report the information to the network side through the wifi hotspot when the mobile terminal is connected to the wifi hotspot, so as to save traffic.
In the application processors described in fig. 4 to 6, when receiving an abnormal indication message sent by a modem in the mobile terminal, a detection module detects whether a common module in the modem is abnormal; if the public module in the modem is normal, the closing module closes a first protocol stack currently used by the modem, and selects a second protocol stack except the first protocol stack from a plurality of protocol stacks supported by the modem; the starting module starts a second protocol stack and performs network registration again by using the second protocol stack; and when the network registration is successful, the recording module records the current position information of the mobile terminal. Therefore, by implementing the embodiment of the invention, when the modem is abnormal, the application processor can quickly restore the modem to be normal by switching other protocol stacks to carry out network registration, thereby quickly solving the problem of abnormal network communication function.
