detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic flowchart of a method for processing an abnormality of a network communication function according to an embodiment of the present invention. In the embodiment of the present invention, the method includes the following steps:

S101. The application processor acquires indication information that the network communication function of the modem is abnormal, and determines that the network communication function of the modem is abnormal according to the indication information.

In some possible implementation manners, the execution body of the method for processing network communication function abnormality provided by the embodiment of the present invention may be implemented by an application processor (English: Application Processor, AP for short) and a modem, that is, an application processor and a modem. Among them, the above-mentioned AP is an ultra-large-scale integrated circuit for extending audio and video functions and a dedicated interface based on a low-power CPU, and is an important component in a smart phone. The AP and the baseband processor (or baseband chip) may be two independent chips, and the baseband chip includes a plurality of modules such as a modem. The AP and the baseband processor may also be integrated into one chip, which may be determined according to actual application scenarios, and is not limited herein. The modem is used to convert the baseband signal into a radio frequency signal, convert the radio frequency signal into a baseband signal, process access layer (AS) and non-access stratum (NAS) signaling, and interface with the AP.

In some possible implementations, the modem supports multiple protocol stacks. When the modem is abnormal, the AP can instruct the modem to register with the network through multiple protocol stacks supported by the modem to restore the communication function. When the modem detects that the network communication function is abnormal; such as crash / assert, the modem will crash crash/dump; the above/downstream channel demodulation CRC high probability failure; etc.; data processing cannot be performed normally, resulting in users not being able to access the Internet and making calls Wait. In order to restore the normal network, when the modem crashes, the AP may send an indication that the network communication function is abnormal, and the above indication information is used to inform the AP that the network communication function is abnormal, and the AP is repaired by the AP. After receiving the indication information of the modem's network communication function abnormality, the AP may determine that the modem's network communication function has an abnormal state. Further, the AP can detect the cause of the abnormal network communication function of the modem, and then perform network repair of the modem according to a specific reason.

In some feasible implementation manners, the reason that the modem handles the network function abnormality may include a protocol stack crash or a protocol stack state abnormality, etc., and is not limited herein.

In some possible implementations, the protocol stack represents the sum of multiple protocols corresponding to a communication system, such as an agreement. The stack includes a Global System for Mobile Communication (GSM) protocol stack, an Enhanced Data Rate for GSM Evolution (EDGE) protocol stack, and a high speed downlink packet access technology (High Speed Downlink). Packet Access (HSPDA) protocol stack, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) protocol stack, Time-Division Duplex Long Term Evolution (LTE) The TDD-LTE protocol stack, the Frequency-Division Duplex (FDD-LTE) protocol stack, and the like, and each communication protocol stack includes multiple sub-protocols, for example, the TD-LTE protocol stack includes Physical layer protocol stack, Media Access Control (MAC) protocol stack, Radio Link Control (RLC) protocol stack, Radio Resource Contro (RRC) protocol stack, and network Network Attached Storage (NAS) protocol stack, etc. No longer.

Specifically, the default protocol stack is one of a plurality of protocol stacks supported by the modem, and is a preset protocol stack. Here, the same default protocol stack can be set for all regions as a protocol stack initially selected by the modem, or A different area or a plurality of areas in a certain area are respectively provided with different default protocol stacks, which are not limited in any embodiment of the present invention.

In a specific implementation, a feasible implementation manner is: the priority level of each protocol stack of the modem can be preset, for example, the priority level of each protocol stack can be set when the modem is shipped from the factory; or, the modem can be configured on the mobile terminal. During the initialization process, the priority level is set according to the network connection and network signal strength when the mobile terminal uses each protocol stack; and so on. Another feasible implementation manner is that the priority of each protocol stack of the modem can be flexibly adjusted, for example, the priority can be set according to the network connection and the network signal strength when the mobile terminal uses each protocol stack in a certain location area; or The priority level of each protocol stack can be set in the order of the common network standard of the mobile terminal; waiting.

It should be noted that the higher the priority level of a certain protocol stack, the mobile terminal can obtain a better network connection or a stronger network signal based on the protocol stack. The highest priority protocol stack in a modem is often referred to as the default protocol stack, and modems typically use the various protocol stacks to implement network registration and network use of the mobile terminal in descending order of priority.

In some feasible implementation manners, the protocol stack checks the combination of signaling parameters and parameters in the communication protocol during operation, and the configuration of these parameters is different in different networks or cells. When a cell or network configuration parameter exceeds the parameters supported by the protocol stack, the protocol stack will crash. Therefore, the AP can determine whether the network parameter of the current cell or the currently connected network includes the network parameter that is not supported by the currently used protocol stack. If the determination is yes, the AP may be abnormal caused by the current protocol stack crash. In addition, some protocol stacks fail to detect pre-detected memory errors, or protocol stacks. Vulnerabilities in the body may also cause the protocol stack to crash. Common memory errors can include memory leaks, memory out of bounds access, reference wild pointers, access to uninitialized variables, stack overflows, byte alignment issues, and more.

In some feasible implementation manners, the modem will not be able to perform network repair by itself after the protocol stack crashes, and the AP is required to assist in the repair of the modem's network communication function. After the modem crashes, the protocol stack may send an indication message to the AP, and the foregoing indication information is used to inform the AP that the network communication function is abnormal. Further, the AP can also detect the status of the modem's network communication function by itself. If the AP detects that the modem is in the protocol stack dead state, it can be determined that the modem's network communication function is abnormal.

In some feasible implementation manners, the protocol stack state abnormality refers to the fact that the detection result of the current state context does not match the expected result in the communication process, for example, when only the uplink packet is detected for a period of time, If there is no downlink packet, the protocol stack is considered abnormal (that is, the uplink and downlink are unreachable). Alternatively, the user equipment (User Equipment, UE for short) intelligent algorithm determines that an abnormality occurs in the protocol stack operation according to the abnormal state of the state. Alternatively, the communication process between the UE and the network side device is affected by an uncertain factor and the situation of out of synchronization occurs; and the like. When the modem detects that the protocol stack is abnormal, the modem will crash and the data processing will not be performed properly, resulting in the UE not being able to access the Internet.

After the modem has a protocol stack exception, it will crash, and then the data processing cannot be performed normally, and the network repair cannot be performed by itself. The AP needs to assist in the repair of the modem's network communication function. After the modem is abnormal in the protocol stack, the AP may send an indication message to the AP, and the foregoing indication information is used to inform the AP that the network communication function is abnormal. Further, the AP can also detect the status of the modem's network communication function by itself. If the AP detects that the modem is in the protocol stack abnormal state, it can be determined that the modem's network communication function is abnormal.

S102. The application processor disconnects the modem from the network connection of the current cell.

S103. The application processor sets the current cell as a forbidden cell, and sets a preset forbidden duration that is prohibited by the forbidden cell.

In some feasible implementation manners, the AP determines that the network communication function of the modem is abnormal (or the abnormal cause of the abnormality of the network communication function), and further determines the abnormal cause of the abnormality of the network communication function of the modem. In a specific implementation, the AP may detect the operating state of the network communication function of the modem according to a preset detection period. If the number of times the network communication function abnormality occurs in the modem is greater than the preset abnormal number threshold within a preset time period, the modem may be disconnected from the modem. The network connection of the current cell. Further, in some feasible implementation manners, the AP may also detect that the modem has multiple network communication function abnormalities within a preset duration, and disconnect the modem from the current cell when the number of abnormal causes is greater than the preset abnormal number threshold. Network connection. It can avoid that the network communication function of the current cell abnormally affects the network communication function of the modem.

Further, in some feasible implementation manners, after the AP disconnects the modem from the network connection of the current cell, the current cell may also be set as a forbidden cell. After the AP disconnects the network connection between the modem and the current cell, the network can be re-searched to establish a network communication connection between the modem and other cells. At this time, the cell is prohibited from being used as a search target for re-searching, and the AP can be prevented from repeatedly trying to establish a network when searching for the network again. The modem is connected to the network of the current cell, thereby avoiding the repeated network communication function abnormality of the modem, and saving the network repair power consumption of the modem.

In some feasible implementation manners, after the AP sets the current cell as a forbidden cell, the AP may also set a preset forbidden duration that prohibits the cell from being disabled. After the forbidden cell is forbidden, the network search object of the network connection is not re-established as a modem within the preset prohibition time. After the preset forbidden time period, the forbidden cell can be re-established as the network search object of the AP to establish the network connection of the modem, and the network communication function of the forbidden cell can be prevented from being banned for a long time, the network resources are wasted, the operation is flexible, and the applicability is high. .

S104. If the duration of the forbidden cell is prohibited is less than the preset forbidden duration, the application processor searches for a cell corresponding to the radio access technology RAT supported by the modem.

In some feasible implementation manners, after the AP disconnects the modem from the network connection of the current cell, the accessible network may be re-searched during a period in which the forbidden cell is prohibited. In a specific implementation, the AP may search for a cell service corresponding to a radio access technology (RAT) supported by the modem. At this time, since the network that the access network has been set to be a forbidden cell when the network communication abnormality occurs in the modem, the AP does not prohibit the search target that is not included in the cell when the AP re-searches the network, thereby avoiding establishing the network connection between the modem and the forbidden cell again, thereby avoiding The network communication function abnormality of the same abnormal cause repeatedly occurs in the modem repeatedly.

S105. If the target cell corresponding to the RAT supported by the modem is searched, the application processor establishes a network connection between the modem and the target cell.

In some feasible implementation manners, if the AP searches for a cell corresponding to the RAT supported by the modem (ie, the target cell), a network connection between the modem and the target cell may be established, and network communication of the modem is implemented by the target cell. The AP establishes a communication connection between the modem and the target cell, and can quickly restore the network communication function of the modem.

Further, in some feasible implementation manners, if the AP cannot search for the target cell corresponding to the RAT supported by the modem, the modem can be restarted to restore the network communication function of the modem, the operation is simple, and the network communication function is highly efficient.

In the embodiment of the present invention, when the AP determines that the network communication function of the modem is abnormal, the network connection between the modem and the current cell may be disconnected, and the current cell is set as the forbidden cell, so as to avoid repeatedly trying to establish communication between the modem and the current cell. A connection that consumes resources to restore the modem's network communication capabilities. Further, the AP may re-search other cells corresponding to the radio access technology supported by the modem, and select a target cell from other cells. Establish a communication connection between the modem and the target cell, restore the network communication function of the modem, and improve the efficiency of network communication function recovery.

2 is a schematic flowchart of another method for processing an abnormality of a network communication function according to an embodiment of the present invention. In the embodiment of the present invention, the method includes the following steps:

S201. The application processor acquires indication information that the network communication function of the modem is abnormal, and determines that the network communication function of the modem is abnormal according to the indication information.

In some possible implementations, the AP detects the network communication function of the modem to determine whether the network communication function of the modem is abnormal. For the implementation manner described in the foregoing step S101, details are not described herein.

S202. The application processor disconnects the modem from the network connection of the current cell.

S203. The application processor sets the current cell as a forbidden cell, and sets a preset forbidden duration for which the forbidden cell is prohibited.

In some possible implementation manners, the specific implementation manner of the AP disconnecting the network connection between the modem and the current cell when the network communication function of the modem is abnormal is described in steps S102 and S103 in the foregoing embodiment, and details are not described herein again.

Further, in some feasible implementation manners, the AP may also preset the monitoring duration of the network communication function of the modem. If the AP detects that the modem has abnormal network communication function multiple times during the monitoring period, the AP may disconnect the modem from the current cell and set the current cell as a forbidden cell. When the AP has abnormal network communication function repeatedly during the monitoring time, the AP disconnects the network connection between the modem and the current cell, which can prevent the current cell from being erroneously prohibited under other factors that cause the modem's network communication function to be abnormal. , affecting the recovery of the modem's network communication function.

In some possible implementations, the AP may pre-establish a list of forbidden cell information and store the list in a specified storage space (eg, a non-volatile storage space of the UE). After the AP is configured to set the current cell as the forbidden cell, the identifier information of the current cell and the preset forbidden duration of the current cell are recorded in the forbidden cell information list, so that the identification information of the forbidden cell and the preset prohibition duration are stored to The above specified storage space. The identifier information of the current cell may be location information of the current cell. The above location information represents an identification of a pre-planned logical location in the mobile communication network. The location information may include a Cell ID (CID), a location area code (LAC), and a Tracking Area Code (TAC), which may be determined according to actual application scenarios, and may not be used here. limit.

S204. The application processor searches for a cell corresponding to the RAT supported by the modem. If the target cell is searched, step S205 is performed, otherwise step S206 is performed.

In some possible implementation manners, the implementation manner of the cell network that the foregoing AP search modem can access may be referred to step S104 in the foregoing embodiment, and details are not described herein again.

Further, if the duration of the forbidden cell is prohibited is less than the preset forbidden duration, and the AP searches for a cell corresponding to the RAT supported by the modem, the forbidden cell is not used as a search target. If the time length of the forbidden cell is prohibited is greater than or equal to the preset forbidden duration, the AP may re-add the forbidden cell to the search object of the re-searching network to avoid waste of network resources.

S205. Establish a network connection between the modem and the target cell.

In some feasible implementation manners, if the AP searches for the target cell, the network connection between the modem and the target cell can be established to quickly restore the network communication function of the modem, the operation is simple, and the network communication function of the modem is restored with high efficiency.

S206. The application processor determines whether the time length of the forbidden cell is prohibited is greater than or equal to the preset prohibition duration. If yes, step S207 is performed; otherwise, step S204 is performed.

S207. The application processor releases the forbidden cell to add the forbidden cell to the re-searched cell, and step S204 is performed.

In some feasible implementation manners, if the duration of the forbidden cell being prohibited is greater than or equal to the preset forbidden duration, the AP may release the forbidden cell, and re-add the forbidden cell to the search object of the cell network supported by the search modem. In a specific implementation, when the AP releases the forbidden cell, the identifier information of the forbidden cell and the corresponding preset forbidden duration may be cleared from the forbidden cell information list. After the AP releases the forbidden cell, the AP may re-search for the cell corresponding to the RAT supported by the modem. At this time, in the current scenario, if the problem that prohibits the cell from appearing before has been repaired, if the AP searches for the previous forbidden cell, it can try to establish a network connection between the modem and the cell again to restore the network communication function of the modem.

S208. The application processor determines whether the abnormal cause of the abnormal network communication function is reported.

Specifically, if the abnormal cause of the abnormal network communication function is reported, the process proceeds to S211, otherwise, S209 is executed.

S209. The application processor acquires an abnormal cause and a log of the abnormality of the network communication function.

In some possible implementation manners, the reason for the abnormality of the network communication function may be referred to the implementation manner described in step S101 in the foregoing embodiment, and details are not described herein again. The above log indicates the operation information of the modem accessing the memory, and the operation information includes: an operation instruction, an operation time, and a return result.

S210. The application processor reports the abnormal cause, the log, and the current location information of the modem to the network. side.

In some possible implementation manners, the AP may report the abnormal cause of the abnormality of the network communication function, the current location information of the modem, and the log to the network side. Specifically, the AP can scan the surrounding WiFi hotspot and establish a connection with the WiFi hotspot. The AP can report the above information to the network side through the WiFi hotspot when the mobile terminal is connected to the WiFi hotspot to save traffic. Further, the AP may also display the abnormal cause of the abnormal network communication function of the modem on the display screen of the mobile terminal for the user to view.

S211, the network communication function abnormal processing ends.

In the embodiment of the present invention, when the AP determines that the network communication function of the modem is abnormal, the modem may disconnect the network connection between the modem and the current cell, and the current cell may be disconnected. It is set to prohibit the cell and can set the preset prohibition time for which the forbidden cell is prohibited, so as to avoid waste of network resources when the network communication function of the modem is abnormal due to other problems, and the current cell is avoided. When the service is abnormal, the modem repeatedly tries to establish a communication connection with the current cell and consumes resources. Further, the AP may re-search other cells corresponding to the radio access technology supported by the modem, select a target cell from other cells, establish a communication connection between the modem and the target cell, restore the network communication function of the modem, and improve the recovery of the network communication function. effectiveness. If the forbidden time of the forbidden cell is greater than or equal to the preset forbidden duration, the AP may release the forbidden cell to disable the cell from accessing the network search object to further protect the network communication function of the modem, and enhance the network communication function of the modem. The flexibility of recovery.
