Description

Technical Field

[0001] This application relates to the technical field of vehicle networking, and in particular, to a method for network recovery of a vehicle head unit, a vehicle head unit, and a storage medium. Background Art

[0002] With the development of technology, vehicles are becoming more and more intelligent. For example, a vehicle can connect to a vehicle network to implement various online service functions (such as remote control functions, OTA functions, entertainment functions, intelligent driving functions, etc.), bringing a good user experience. However, during the use of the vehicle, it may be disconnected from the vehicle network, resulting in the inability to use various online service functions. Therefore, it is necessary to restore network connection when the vehicle is disconnected from the vehicle network.

[0003] Currently, one way for a vehicle to restore network connection is to frequently perform APN dialing to attempt to restore network connection, resulting in waste of computing resources and high power consumption. Summary of the Invention

[0004] This application provides a method for network recovery of a vehicle head unit, a vehicle head unit, and a storage medium, which is used to solve the problem in the prior art that frequent APN dialing results in waste of computing resources and high power consumption.

[0005] In a first aspect, this application provides a method for network recovery of a vehicle head unit, which is applied to a vehicle head unit. The method provided by this application includes:

[0006] When the vehicle head unit detects that the APN connection is disconnected, initiate an APN dial-up connection;

[0007] When the APN dial-up connection fails, determine the number of times of the APN dial-up connection that has been initiated;

[0008] When the number of times is lower than a set number threshold, start timing, and determine the dialing duration interval for the next APN dial-up connection according to the number interval to which the number of times belongs, where the lower the lower limit value of the number interval to which the number of times belongs, the longer the dialing duration interval;

[0009] When the timing reaches the dialing duration interval, return to execute the operation of initiating an APN dial-up connection until the number of times reaches the set number threshold.

[0010] In some embodiments, after initiating an APN dial-up connection, the method provided by this application further includes:

[0011] When the APN dial-up connection is successful, request to connect to the DNS server;

[0012] When it is determined that the connection to the DNS server fails, disconnect the APN connection and return to the operation of initiating an APN dial-up connection.

[0013] In some embodiments, determining that the connection to the DNS server fails includes:

[0014] Sending a connection request to the DNS server;

[0015] Performing a count when no acknowledgment packet is received from the DNS server in response to the connection request;

[0016] When the count value is lower than a set count threshold, returning to perform the operation of sending a connection request to the DNS server;

[0017] When the count value reaches the set count threshold, determining that the connection to the DNS server fails.

[0018] In some embodiments, after requesting to connect to the DNS server, the method provided by this application further includes:

[0019] When the request to connect to the DNS server is successful, determining whether the traffic of the network card of the in-vehicle unit within a preset duration is greater than a set traffic threshold;

[0020] If it is greater than the set traffic threshold, clearing the recorded number of dialing attempts.

[0021] In some embodiments, when determining that the connection to the DNS server fails, a preset network fault recovery policy is executed, where the network fault recovery policy is that the corresponding network fault recovery operations are different when the recovery times interval to which the network fault recovery times belong is different, and the lower limit value of the recovery times interval to which it belongs is larger, the corresponding network fault recovery time is longer, and the scope of influence on the services of the in-vehicle unit is wider.

[0022] In some embodiments, when determining that the connection to the DNS server fails, executing a preset network fault recovery policy includes:

[0023] When the network fault recovery times reach the first count threshold, re-initiate an APN dial-up connection;

[0024] When the network fault recovery times reach the first count threshold, perform the operation of restarting the network service of the in-vehicle unit;

[0025] When the network fault recovery times reach the third count threshold, perform the operation of restarting the operating system of the in-vehicle unit.

[0026] In some embodiments, the method provided by this application further includes:

[0027] When the number of dialing attempts is higher than a set number threshold, clearing the recorded number of dialing attempts;

[0028] Wait for the set duration, and return to execute the step of the in-vehicle unit initiating an APN dial-up connection when detecting that the APN is disconnected until it is detected that the APN connection is successful.

[0029] In a second aspect, the present application also provides an in-vehicle unit, including a memory, a processor, and a computer program stored in the memory and executable on the processor. The in-vehicle unit is characterized in that when the processor executes the computer program, the in-vehicle unit executes the method provided in the first aspect of the present application.

[0030] In a third aspect, the present application also provides a storage medium storing a computer program, and when the computer program is executed by a processor, the in-vehicle unit executes the method provided in the first aspect of the present application.

[0031] In a fourth aspect, the present application also provides a computer program product including a computer program, and when the computer program is run, the in-vehicle unit executes the method provided in the first aspect of the present application.

[0032] The present application provides a method for network recovery of an in-vehicle unit, an in-vehicle unit, and a storage medium. When the APN dial-up connection fails, determine the number of times of the APN dial-up connection that has been initiated; when the number of times is lower than the set number threshold, start timing, and determine the dialing duration interval for the next APN dial-up connection according to the number interval to which the number of times belongs. Since the lower limit value of the number interval to which the number of times belongs is higher, the dialing duration interval is longer. When the timing reaches the dialing duration interval, return to execute the operation of initiating an APN dial-up connection until the number of times reaches the set number threshold.

[0033] It can be understood that when the APN is just disconnected, the difficulty of restoring the APN connection is uncertain at this time. In order to restore the APN connection as soon as possible, the above-mentioned dialing duration interval is set to be smaller. As the number of times of dialing increases, the difficulty of restoring the APN connection also increases. In order to avoid the in-vehicle unit from frequently initiating APN dial-up connections, the above-mentioned dialing duration interval is set to be larger. In this way, when the lower limit value of the number interval to which the number of times belongs is higher and the dialing duration interval is longer, it is possible to restore the APN connection as early as possible while avoiding the in-vehicle unit from frequently initiating APN dial-up connections; thus, it is possible to save computing resources and power consumption while satisfying the user experience as much as possible.

[0041] Hereinafter, the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0042] An embodiment of the present application provides a network recovery method for a vehicle-mounted device, which is applied to the vehicle-mounted device. AsFigure 1 As shown in the figure, the method provided by the embodiment of the present application includes:

[0043] S101: Detect whether the APN is disconnected. If so, execute S102.

[0044] APN (Access Point Name) is the network access point, which determines the access method for the in-vehicle unit to access a specific network. Exemplarily, the in-vehicle unit can connect to different networks through multiple APNs to implement different vehicle service functions. For example, the in-vehicle unit can connect to Network 1 through APN1 to implement the remote control function, connect to Network 2 through APN2 to implement the in-vehicle unit interaction function, connect to Network 3 through APN3 to implement the over-the-air download function, and connect to Network 4 through APN4 to implement the intelligent driving function. When it is detected that a certain APN is disconnected from the network, the in-vehicle unit cannot implement the corresponding vehicle service function. Therefore, it is necessary to perform a network recovery operation on this APN.

[0045] S102: Initiate an APN dial-up connection.

[0046] Exemplarily, APN dial-up refers to dialing by configuring the access point name (APN) to attempt to connect to the base station of the network. It should be noted that only one APN dial-up connection is initiated each time.

[0047] S103: Determine whether the APN dial-up connection is successful. If not, execute S104; optionally, as Figure 2 shown in the figure, if so, execute S108.

[0048] S104: Determine the number of dialing attempts for the initiated APN dial-up connection.

[0049] It can be understood that the number of dialing attempts for the initiated APN dial-up connection is the number of failed APN dial-up connection attempts.

[0050] S105: Determine whether the number of dialing attempts is lower than the set number threshold; if so, execute S106; optionally, if not, execute S113.

[0051] It should be noted that when the number of dialing attempts is lower than the set number threshold (such as 12 times), it indicates that the reason for the dialing failure may be due to the instability of the in-vehicle unit's own system. If the number of dialing attempts reaches the set number threshold, it indicates that the dialing failure is not caused by the instability of the in-vehicle unit itself (it may be due to reasons such as base station failure).

[0052] S106: Start timing, and determine the dialing duration interval for the next APN dial-up connection according to the number interval to which the number of dialing attempts belongs.

[0053] Exemplarily, a timer timer can be started to start timing. It can be understood that the smaller the number of dials, the higher the probability of dialing failure caused by the instability of the in-vehicle system itself. Therefore, when the lower limit value of the number range to which the number of dials belongs is higher, the dialing duration interval is set longer. In this way, it is possible to recover the APN connection as early as possible while avoiding the in-vehicle unit from frequently initiating APN dial-up connections; thus, it is possible to save computing resources and power consumption while satisfying the user experience as much as possible.

[0054] Exemplarily, the relationship between the number range to which the number of dials belongs and the dialing duration interval can be as shown in Table 1 below.

[0055] Number of dialing 1 2 3 4 5 6 7 8 9 10 11 12 Dialing duration interval 10s 10s 10s 40s 40s 40s 80s 80s 80s 120s 120s 120s

[0056] Table 1

[0057] S107: Determine whether the timing has reached the dialing duration interval. If so, return to execute S102.

[0058] In summary, the embodiment of the present application provides a method for network recovery of an in-vehicle unit. When the APN dial-up connection fails, determine the number of APN dial-up connections that have been initiated; when the number of dials is lower than the set number threshold, start timing, and determine the dialing duration interval for the next APN dial-up connection according to the number range to which the number of dials belongs. Since the lower limit value of the number range to which the number of dials belongs is higher, the dialing duration interval is longer. When the timing reaches the dialing duration interval, return to execute the operation of initiating an APN dial-up connection until the number of dials reaches the set number threshold.

[0059] It can be understood that when the APN just disconnects, the difficulty of restoring the APN connection is uncertain at this time. In order to restore the APN connection as soon as possible, the above-mentioned dialing duration interval is set smaller. As the number of dials increases, the difficulty of restoring the APN connection also increases. In order to avoid the in-vehicle unit from frequently initiating APN dial-up connections, the above-mentioned dialing duration interval is set larger. In this way, when the lower limit value of the number range to which the number of dials belongs is higher and the dialing duration interval is longer, it is possible to recover the APN connection as early as possible while avoiding the in-vehicle unit from frequently initiating APN dial-up connections; thus, it is possible to save computing resources and power consumption while satisfying the user experience as much as possible.

[0060] In some embodiments, as Figure 2 shown, the method provided by the embodiment of the present application further includes:

[0061] S108: When the APN dial-up connection is successful, request to connect to the DNS server.

[0062] The DNS (Domain Name System) server is a core component of the domain name system, mainly responsible for converting the domain name that is easy for humans to remember into an IP address that can be recognized by a computer for network access.

[0063] S109: Determine whether the connection to the DNS server fails. If so, execute S110; if not, execute S111.

[0064] Specifically, S109 can be implemented as follows: Send a connection request to the DNS server; perform a count when no confirmation packet is received from the DNS server in response to the connection request; return to execute the operation of sending a connection request to the DNS server when the count value is lower than the set count threshold (such as 3 times or 4 times, etc.); determine that the connection to the DNS server fails when the count value reaches the set count threshold. It can be understood that when the connection to the DNS server fails, it may be caused by a base station failure or other reasons.

[0065] S110: Disconnect the APN connection and return to the operation of S102.

[0066] After disconnecting the APN connection and successfully initiating an APN dial-up connection again, it may be connected to a different base station. If the aforementioned failure to connect to the DNS server is caused by a base station failure, the network connection can be restored.

[0067] S111: Determine whether the traffic of the network card of the in-vehicle unit within a preset duration is greater than the set traffic threshold; if so, execute S112.

[0068] Exemplarily, if the traffic of the network card of the in-vehicle unit within a preset duration (such as 30s) is greater than the set traffic threshold, it indicates that the in-vehicle unit can also start to normally execute in-vehicle unit services (such as intelligent driving and remote control, etc.), which means that the in-vehicle unit has successfully restored the network connection, and thus S112 can be executed.

[0069] S112: Clear the recorded number of dialing attempts.

[0070] In some embodiments, when the number of dialing attempts is higher than the set number threshold, the method provided by the embodiments of the present application may further include:

[0071] S113: Clear the recorded number of dialing attempts.

[0072] S114: Wait for the set duration and return to execute S102.

[0073] Understandably, when the number of dialing attempts is higher than the set number threshold, it indicates that there may be a problem with the network in the short term. To avoid wasting computing resources caused by frequent dialing, the recorded number of dialing attempts can be cleared, and wait for a preset duration (such as 150s), then start the next cycle of dialing and record the number of dialing attempts again.

[0074] In addition, in some embodiments, when it is determined that the connection to the DNS server fails, a preset network failure recovery strategy is executed. Among them, the network failure recovery strategy is that when the recovery times interval to which the network failure recovery times belong is different, the corresponding network failure recovery operations are different, and the lower limit value of the recovery times interval to which it belongs is larger, the longer the corresponding network failure recovery time is executed, and the wider the scope of business impact on the in-vehicle unit is. In this way, the network failure can be recovered while minimizing the impact on the in-vehicle unit's business and the time spent.

[0075] For example, when the number of network failure recoveries reaches the first number threshold, then re-initiate the APN dial-up connection. When the number of network failure recoveries reaches the first number threshold, execute the operation of restarting the network service of the in-vehicle unit. When the number of network failure recoveries reaches the third number threshold, execute the operation of restarting the operating system of the in-vehicle unit. Understandably, the scope of business impact on the in-vehicle unit of re-initiating the APN dial-up connection, restarting the network service of the in-vehicle unit, and restarting the operating system of the in-vehicle unit decreases in turn; the time required for re-initiating the APN dial-up connection, restarting the network service of the in-vehicle unit, and restarting the operating system of the in-vehicle unit increases in turn.

[0076] In addition, as Figure 3 shown, an embodiment of the present application provides a network recovery device for an in-vehicle unit, which is configured in the in-vehicle unit. It should be noted that the basic principle and the technical effects generated by the network recovery device for the in-vehicle unit provided by the embodiment of the present application are the same as those of the above embodiments.
