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.
In the embodiment of the invention, the mobile terminal can comprise equipment with a network function, such as a smart phone, a tablet computer, a smart wearable device and the like, a Modem (Modem) and an AP (access point) processor are arranged in the mobile terminal, the mobile terminal realizes the network function through the built-in Modem, and the AP processor is used for processing the abnormity generated by the Modem. The embodiment of the invention is used for solving the problem how a modem built in the mobile terminal locates the abnormal reason and executing the abnormal processing flow according to the abnormal reason when the mobile terminal cannot be connected to the Internet to influence the network use.
The following describes in detail a method for handling network communication function abnormality according to an embodiment of the present invention with reference to fig. 1 to fig. 2. It should be noted that the method described below can be applied to a mobile terminal, and specifically can be implemented by interaction between a Modem (Modem) and an AP processor built in the mobile terminal.
Referring to fig. 1, a flow chart of a method for handling network communication function abnormality according to an embodiment of the present invention is shown, the method may include steps S101-S108, where steps S101-S103 occur in a modem, i.e., are executed by the modem; and S104-S108 occur in the AP processor, i.e., are performed by the AP processor:
s101: detecting whether special bearer processing is abnormal or not by a modem, wherein the abnormal special bearer processing comprises the following steps: dedicated bearer activation failure or dedicated bearer modification failure.
The protocol Stack (protocol Stack) refers to the sum of all layers of protocols in the network, and is used for visually reflecting the process of file transmission in the network, and the protocols of the Internet protocol Stack from top to bottom are as follows: application layer, transport layer, network layer, link layer, physical layer. The application layer protocol may include: HTTP (HyperText Transfer Protocol), FTP (text Transfer Protocol), TFTP (simple File Transfer Protocol), TELNET (remote terminal Protocol), DNS (Domain Name System), and the like. The transport layer protocol may include: TCP (Transmission Control Protocol), UDP (User Datagram Protocol). The network layer Protocol is typically IP (Internet Protocol, Protocol for interconnecting networks). The link layer protocol may include: wifi, ethernet, token ring, FDDI (fiber distributed Data Interface), MAC (Media Access Control), etc. Based on the diversity of protocols included in each layer, in order to enable the mobile terminal to simultaneously support network communication systems such as 2G/3G/4G, LTE (Long Term Evolution ) of different operators, the modem may generally support two or more protocol stacks, and the two or more protocol stacks supported by the modem have a high or low priority, where one possible implementation manner is as follows: the priority levels of the various protocol stacks of the modem may be preset, for example: the priority level of each protocol stack can be set when the modem leaves a factory; or, in the process that the modem is configured in the mobile terminal and initialized, the priority level can be set according to the network connection and the network signal strength when the mobile terminal uses each protocol stack; and so on. Another possible implementation is: the priority levels of the various protocol stacks of the modem can be flexibly adjusted, for example: the priority level can be set according to the network connection and the network signal strength when the mobile terminal uses each protocol stack in a certain position area; or, the priority level of each protocol stack can be set according to the sequence of the common network communication system of the mobile terminal; and so on. It should be noted that the higher the priority level of a certain protocol stack is, the better network connection or stronger network signal can be obtained by the mobile terminal based on the protocol stack. The protocol stack with the highest priority in the modems is generally called a default protocol stack, and the modems generally use the protocol stacks to realize network registration and network use of the mobile terminal from high to low in the order of priority.
The modem typically requires dedicated bearer handling, including dedicated bearer activation or dedicated bearer modification, during network registration or network usage of the mobile terminal. The modem initiates the dedicated bearer activation/modification procedure based on the currently used protocol stack, i.e., the first protocol stack as described in embodiments of the present invention. The dedicated bearer activation or dedicated bearer modification may be initiated by the mobile terminal side (in particular by a modem built in the mobile terminal) or by the network side. The network side may specifically initiate the dedicated BEARER activation or the dedicated BEARER modification by sending a dedicated BEARER activation REQUEST (ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST) or a dedicated BEARER modification REQUEST (modification EPS BEARER CONTEXT REQUEST) to the mobile terminal. The modem of the mobile terminal initiates the dedicated BEARER activation or the dedicated BEARER modification by sending a BEARER RESOURCE allocation REQUEST message (BEARER RESOURCE allocation REQUEST) or a BEARER RESOURCE modification REQUEST message (BEARER RESOURCE modification REQUEST).
However, during the dedicated bearer activation or dedicated bearer modification, if the following occurs on the mobile terminal side, the dedicated bearer processing will generate an exception, for example: a dedicated bearer activation failure or a dedicated bearer modification failure; these include: the dedicated BEARER identity to be activated conflicts with an existing default BEARER identity, the dedicated BEARER identity to be activated conflicts with an existing dedicated BEARER identity, the default BEARER associated with the dedicated BEARER to be activated is not established, and the RRC (Radio Resource Control) layer indicates that the message transmission fails when a dedicated BEARER activation complete message (ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT) or a dedicated BEARER modification complete message (MODIFY EPS BEARER CONTEXT ACCEPT) is sent. In S101, the modem may determine whether the dedicated bearer activation or the dedicated bearer modification fails by detecting whether the above condition exists during the dedicated bearer activation or the dedicated bearer modification, so as to determine whether the dedicated bearer processing of the modem is abnormal.
S102: and if the exception occurs, the modem generates an exception handling notice, and the exception handling notice is used for indicating the special bearer handling of the modem to have the exception by the AP processor so as to carry out exception handling by the AP processor.
S103: the modem sends the exception handling notification to an AP processor of the mobile terminal.
S104: the AP processor receives an exception handling notification sent by a modem of the mobile terminal, wherein the exception handling notification is used for indicating that the special bearing processing of the modem is abnormal. The exception handling notification may trigger the AP processor to perform a subsequent exception handling procedure.
S105: the AP processor detects whether the abnormal times of the special bearing processing of the modem in a preset time period exceeds a preset threshold value; if the detection result is negative, the step S106 is executed; if the detection result is yes, the process proceeds to step S107.
Wherein, the preset time period can be set according to actual needs, for example: the preset period may be one day, 10 hours, etc. The preset threshold value indicates the maximum value of the number of times that the same anomaly is allowed to occur, and can be set according to actual needs, for example: the preset threshold may be 20, 50, etc. In this step, since the modem may notify the AP processor to perform exception handling when detecting that the dedicated bearer handling is abnormal, the AP processor may count the number of received exception handling notifications to determine the number of times the dedicated bearer handling is abnormal.
S106: the AP processor resets the modem; and then ends. Resetting the modem is restoring factory settings of the modem.
S107: and the AP processor closes a first protocol stack which causes an exception currently in the modem and opens a second protocol stack, wherein the modem supports at least two protocol stacks.
The first protocol stack is a protocol stack currently used by the modem when the special bearer processing generates an exception, and the second protocol stack is any one of at least two protocol stacks supported by the modem except the first protocol stack. The embodiment of the invention can adopt the following strategies to determine the second protocol stack: (1) selecting a protocol stack with a priority level lower than that of a first protocol stack from at least two protocol stacks supported by the modem as a second protocol stack; (2) respectively measuring the signal intensity of cell signals corresponding to all protocol stacks supported by the modem except the first protocol stack, and taking the protocol stack with the maximum signal intensity as a second protocol stack; (3) and selecting a protocol stack with a priority level higher than that of the first protocol stack from at least two protocol stacks supported by the modem as a second protocol stack. In practical applications, the embodiment of the present invention may also determine the second protocol stack by using other policies, which is not limited in the present invention.
S108: if the mobile terminal successfully performs network registration based on the second protocol stack, the AP processor records the current attribute of the mobile terminal, where the attribute includes: location information, LAC information, or CID information.
In specific implementation, after the first protocol stack is closed, the mobile terminal becomes in a no-service state; starting the selected second protocol stack, and performing network registration by using the second protocol stack, where the network may include but is not limited to: for example, the registration process of the LTE network or the 2G/3G network is as follows: the mobile terminal initiates an attachment request (attach request) to the network side based on the second protocol stack, if the network side allows the mobile terminal to access, an attachment response (attach accept) is returned to the mobile terminal, which indicates that the network registration is successful, and the mobile terminal is converted from the no-service state to the 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. If the mobile terminal successfully performs network registration based on the second protocol stack, the mobile terminal can access to the network and recover network service. The location information and LAC information of the mobile terminal may be specifically obtained by a base station Positioning technology or a GPS (Global Positioning System) technology, and the CID information of the mobile terminal may be specifically obtained from an operating System of the mobile terminal.
Referring to fig. 2, a flow chart of another method for handling network communication function abnormality according to an embodiment of the present invention is shown, the method may include steps S201-S215, where steps S201-S203 occur in a modem, that is, are executed by the modem; and S204-S215 occur in the AP processor, i.e., are performed by the AP processor:
s201: detecting whether special bearer processing is abnormal or not by a modem, wherein the abnormal special bearer processing comprises the following steps: dedicated bearer activation failure or dedicated bearer modification failure. If the abnormality occurs, the step S202 is carried out; otherwise, return to step S201.
S202: the modem generates an exception handling notification for indicating with the AP processor that special bearer handling of the modem is anomalous for exception handling by the AP processor.
S203: the modem sends the exception handling notification to an AP processor of the mobile terminal.
S204: the AP processor receives an exception handling notification sent by a modem of a terminal, wherein the exception handling notification is used for indicating that the special bearing processing of the modem is abnormal. The exception handling notification may trigger the AP processor to perform a subsequent exception handling procedure.
S205: the AP processor detects whether the abnormal times of the special bearing processing of the modem in a preset time period exceeds a preset threshold value; if the detection result is negative, go to step S206; if the detection result is yes, the process proceeds to step S207.
S206: the AP processor resets the modem; thereafter, the process proceeds to step S212.
S207: and the AP processor closes a first protocol stack which causes an exception currently in the modem and opens a second protocol stack, wherein the modem supports at least two protocol stacks.
S208: the AP processor determines whether the network registration of the mobile terminal based on the second protocol stack is successful, and if so, proceeds to step S209; otherwise, the process proceeds to step S211. If the mobile terminal successfully performs network registration based on the second protocol stack, the mobile terminal can access to the network and recover network service. If the mobile terminal fails to register the network based on the second protocol stack, the mobile terminal still cannot be connected to the network, that is, the network service of the mobile terminal is not recovered.
S209: the AP processor records the current attribute of the mobile terminal, wherein the attribute comprises the following steps: location information, LAC information, or CID information. The location information and LAC information of the mobile terminal may be specifically obtained by a base station positioning technology or a GPS technology, and the CID information of the mobile terminal may be specifically obtained from an operating system of the mobile terminal.
S210: the AP processor detects whether the current attribute of the mobile terminal changes, and if so, the step S211 is carried out; otherwise, return to step S210.
S211: the AP processor restores the switch state of a default protocol stack of at least two protocol stacks supported by the modem and/or resets the modem.
The process of restoring the on-off state of a default protocol stack in at least two protocol stacks supported by the modem may be understood as a reset process of a protocol stack; and the process of resetting the modem may be understood as restoring factory settings of the modem. It is understood that the default protocol stack here may be 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 (i.e. the protocol stack that has been closed and causes the exception to the dedicated bearer processing), this step is equivalent to restarting the first protocol stack. Because the mobile terminal has the characteristics of mobility and platform updating, when the mobile terminal moves in position or updates the platform, the current attribute of the mobile terminal changes, and the network connection condition of the mobile terminal may also change, for example: the mobile terminal can perform network connection at the position A based on the second protocol stack, however, the network connection cannot be performed based on the second protocol stack when the mobile terminal moves from the position A to the position B; similarly, the mobile terminal may not be able to connect to the network at location a based on the first protocol stack, but may connect to the network at location B. Therefore, after the first protocol stack is restarted, the current attribute of the mobile terminal is changed, so that the mobile terminal can recover the network use based on normal network registration of the restarted first protocol stack.
S212: the AP processor detects whether a report record of the abnormal reason exists, if not, the step S213 is carried out; if yes, the process is finished.
In the embodiment of the present invention, the abnormality cause is: dedicated bearer activation failure or dedicated bearer modification failure. If the detection result is that the report record of the abnormal reason exists, the abnormal reason is reported, and the abnormal reason is not reported to avoid redundancy. If the detection result is no, that is, there is no report record of the abnormal reason, which indicates that the abnormal reason is not reported, the step S213 and the subsequent steps need to be performed to report the abnormal reason.
S213: the AP processor generates an exception report message which comprises an exception reason, an exception handling log and the current attribute of the mobile terminal. Wherein the anomaly cause is a dedicated bearer activation failure or a dedicated bearer modification failure of the modem. The exception handling log is used to describe a process of exception handling executed for the current exception cause in the foregoing steps in this embodiment, and may include: (1) closing a first protocol stack which causes abnormity at present and opening a second protocol stack; (2) when the network registration of the mobile terminal based on the second protocol stack fails or when the current attribute of the mobile terminal is changed, restoring the on-off state of a default protocol stack in at least two protocol stacks supported by the modem, and/or resetting the modem; and so on. If the attribute of the mobile terminal is not changed, the current attribute of the mobile terminal here refers to the current attribute recorded in step S209; if the attribute of the mobile terminal changes, the current attribute of the mobile terminal refers to the changed current attribute detected in step S210. In a possible implementation manner of this embodiment, after step S213, the exception report message may be output in the mobile terminal, so that a user at the mobile terminal may view the exception report message, thereby knowing why the mobile terminal cannot perform network connection, knowing an exception handling process, and making explicit the current attribute of the mobile terminal. In another possible implementation manner of this embodiment, step S213 may be followed by steps S214 to S215:
s214: the AP processor judges whether the mobile terminal is in a Wifi network or not, and if the judgment result is yes, the step S215 is carried out; otherwise, ending.
S215: and the AP processor reports the exception report message to a server.
S214-S215 show that the abnormal report message is reported only in the Wifi network, but not in the Wifi network, so that the charging flow of the mobile terminal can be effectively saved, and the transmission efficiency in the reporting process can be ensured.
In a specific implementation, the following implementation manners may also exist in the embodiment: after performing steps S201-S209, it is possible to directly jump to perform steps S212-S215 without performing the attribute detection process.
Referring to fig. 3, a flow chart of another method for handling network communication function abnormality according to an embodiment of the present invention is shown, the method may include steps S301 to S313, where steps S301 to S303 occur in a modem, that is, are executed by the modem; and S304-S313 occur in the AP processor, i.e., are performed by the AP processor:
s301: the modem detects whether special bearer processing is abnormal, wherein the abnormal special bearer processing comprises the following steps: dedicated bearer activation failure or dedicated bearer modification failure. If the abnormality occurs, the step S302 is carried out; otherwise, return to step S301.
S302: the modem generates an exception handling notification for indicating with the AP processor that special bearer handling of the modem is anomalous for exception handling by the AP processor.
S303: the modem sends the exception handling notification to an AP processor of the mobile terminal.
S304: the AP processor receives an exception handling notification sent by a modem of a terminal, wherein the exception handling notification is used for indicating that the special bearing processing of the modem is abnormal. The exception handling notification may trigger the AP processor to perform a subsequent exception handling procedure.
S305: the AP processor detects whether the abnormal times of the special bearing processing of the modem in a preset time period exceeds a preset threshold value; if the detection result is yes, the step S306 is executed; otherwise, the process proceeds to step S310.
S306: and the AP processor closes a first protocol stack which causes an exception currently in the modem and opens a second protocol stack, wherein the modem supports at least two protocol stacks.
S307: if the mobile terminal successfully performs network registration based on the second protocol stack, the AP processor records the current attribute of the mobile terminal, where the attribute includes: location information, LAC information, or CID information.
S308, the AP processor detects whether the current attribute of the mobile terminal changes, and if so, the step S309 is carried out; otherwise, return to step S308.
S309: the AP processor restores the switch state of a default protocol stack of at least two protocol stacks supported by the modem and/or resets the modem.
S310: the AP processor detects whether a report record of the abnormal reason exists, and if not, the step S311 is carried out; otherwise, ending.
S311: the AP processor generates an exception report message which comprises an exception reason, an exception handling log and the current attribute of the mobile terminal.
S312: the AP processor judges whether the mobile terminal is in a Wifi network or not, and if the judgment result is yes, the step S313 is carried out; otherwise, ending.
S313: and the AP processor reports the exception report message to a server.
In a specific implementation, the following implementation manners may also exist in the embodiment: after performing steps S301 to S307, steps S310 to S313 may be directly skipped without performing the attribute detection process.
Through the description of the above embodiments, in the embodiments of the present invention, the modem of the mobile terminal may detect whether the dedicated bearer processing is abnormal, and if the dedicated bearer processing is abnormal, the modem notifies the AP processor to perform exception processing, where the exception processing process may include: the method comprises the steps of detecting whether the number of times of abnormity of the special bearing processing in a preset time period exceeds a preset threshold value, resetting a modem if the number of times of abnormity of the special bearing processing in the preset time period does not exceed the preset threshold value, closing a first protocol stack which causes abnormity at present and opening a second protocol stack if the number of times of abnormity of the special bearing processing exceeds the preset threshold value, and executing further processing including recording the current attribute of the mobile terminal or resetting the protocol stack and resetting the modem according to the result of network registration of the mobile terminal based on the second protocol stack.
