Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a vehicle-mounted communication method, apparatus, system, and storage medium. Background Art

[0002] 5G network is the abbreviation of the fifth-generation mobile communication technology. Compared with the previous generations of mobile communication technologies, the 5G network has higher bandwidth, lower latency, and higher reliability. This means that users can transmit more data in a shorter time, achieve faster download and upload speeds, and at the same time obtain better communication quality and more stability.

[0003] Currently, some new vehicles and in-vehicle entertainment systems have begun to support connection to the 5G network. Connecting the in-vehicle unit to the 5G network can provide faster data transmission speed and more stable network connection, thus achieving a smoother entertainment and navigation experience. The 5G network also provides more reliable connectivity for vehicles, supports communication between vehicles and real-time data transmission, and helps to realize advanced functions such as intelligent transportation and vehicle autonomous driving.

[0004] In the existing in-vehicle unit communication method, when there is a connection problem with the 5G network, it will directly control the main network card to restart or initialize. However, restarting the network card will cause some application functions to be forcibly interrupted in a short time, resulting in a bad user experience.

[0059] The technical solution of the present application will be further described in detail below through the drawings and embodiments. Description of the Drawings

[0060] The drawings are used to provide a further understanding of the present application, and constitute a part of the specification. Together with the embodiments of the present application, they are used to explain the present application, and do not constitute a limitation to the present application. In the drawings:

[0061] Figure 1 is a flowchart of a vehicle head unit communication method in an embodiment of the present application;

[0063] Figure 3 is a hardware structural schematic diagram of a vehicle head unit communication system in an embodiment of the present application. Detailed Embodiments

[0064] The following describes the preferred embodiments of the present application with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0065] Figure 1 is a flowchart of a vehicle head unit communication method in an embodiment of the present application. As Figure 1 shown, the method can be implemented as the following steps S101 - S103:

[0066] In step S101, when it is detected that the vehicle head unit starts up, it controls the first user identity module in the vehicle head unit to initiate a data dial to the fifth-generation mobile communication network;

[0067] In step S102, when the first user identity module fails to dial, it determines whether the reason for the dialing failure is a connection disconnection;

[0068] In step S103, when the reason for the dialing failure is a connection disconnection, the second user identity module in the in-vehicle unit is controlled to initiate a data dialing to the 5G mobile communication network.

[0069] In this application, when it is detected that the in-vehicle unit is started, the first user identity module in the in-vehicle unit is controlled to initiate a data dialing to the 5G mobile communication network; specifically, some in-vehicle units are equipped with two subscriber identification modules (SIMs). The user can set in advance which subscriber identification module is the primary card, that is, the first user identity module, and which is the secondary card, that is, the second user identity module.

[0070] When the first user identity module fails to dial, it is judged whether the reason for the dialing failure is a connection disconnection.

[0071] Specifically, during the process of the in-vehicle unit using the 5G network, sometimes there will be a network connection exception resulting in a dialing failure. There are many reasons for the network connection exception. For example, the 5G network base station signal is blocked by obstacles, resulting in a weak signal, the network firmware or driver of the device is updated, network congestion, operator equipment maintenance, APN configuration problems, insufficient access rights, and individual software cannot connect to the network. Among them, the update of the network firmware or driver of the device, operator equipment maintenance, APN configuration problems, and insufficient access rights will cause the network connection to be disconnected, resulting in a dialing failure. Sometimes these problems can be solved by restarting.

[0072] Some will not cause a connection disconnection. For example, problems such as weak signal, network congestion, and individual software not being able to connect to the network. During the vehicle driving process, usually within a short time, it will enter the 5G network coverage area again, and network congestion will also recover by itself within a certain period of time. The reason why individual software cannot connect to the network is usually due to network problems or server maintenance of the software provider. After the software provider fixes the relevant problems, it will also return to normal. Therefore, these network connection exceptions will not cause a connection disconnection, and these problems cannot be solved by restarting.

[0073] Therefore, only when the reason for the dialing failure is a connection disconnection, the second user identity module in the in-vehicle unit is controlled to initiate a data dialing to the 5G mobile communication network.

[0074] In addition, in this application, if the first user identity module dials successfully, the transmission quality of each APN (Access Point Name) will still be detected. When an APN with abnormal transmission quality appears, the network abnormality is determined and the type of network abnormality is judged; when the network abnormality type is a data plane abnormality, the vehicle status is determined; specifically, the data plane abnormality usually refers to weak signals, network congestion, and individual software cannot connect to the Internet. Problems; when the vehicle is in a stopped state and the duration of the transmission quality abnormality reaches a first duration, the second user identity module in the vehicle is controlled to initiate data dialing to the fifth-generation mobile communication network; when the vehicle is in a driving state and the duration of the transmission quality abnormality reaches a second duration, the second user identity module in the vehicle is controlled to initiate data dialing to the fifth-generation mobile communication network. Specifically, if the duration of the abnormal transmission quality reaches a certain length of time, it is very likely that the area where the vehicle is located is not in the 5G network coverage of the operator corresponding to the first user identity identification module. If the vehicle is stationary, it cannot enter the 5G network coverage of the operator corresponding to the first user identity identification module in a short period of time. If the vehicle is in motion, it may enter the 5G network coverage of the operator corresponding to the first user identity identification module in a short period of time. Therefore, in this application, the first duration is usually set to be shorter, such as 5 seconds, and the second duration is longer, such as 3 minutes. This can reserve a certain amount of time for the vehicle to re-enter the 5G network coverage of the operator corresponding to the first user identity identification module.

[0075] In this application, when the vehicle is stationary, if the first user identity module fails to dial, it will retry. If the retry fails, it is determined that the dialing has failed, and a static restart flag is set in the vehicle computer. The static restart flag is used to indicate that the dialing has been retried and failed, and when the static restart flag exists, further retries can be prohibited to avoid the waste of computing resources caused by retries. When the duration of the vehicle computer connecting to the 5G network through the second user identity module reaches a third duration, the static restart flag will be cleared. When the static restart flag is cleared, the first user identity module in the vehicle computer is controlled to retry connecting to the 5G network.

[0076] The beneficial effect of the present application is that when the first user identity module fails to dial, it will not try to solve the problem by restarting, but will continue to determine whether the cause of the dialing failure is a disconnection; when the cause of the dialing failure is a disconnection, the second user identity module in the vehicle computer is controlled to initiate data dialing to the fifth-generation mobile communication network, so that when the dialing fails, the problem can be avoided as much as possible by restarting, the number of times the application function is forcibly interrupted is reduced, and the user experience is improved.

[0077] In one embodiment, the method can also be implemented as the following steps A1-A5:

[0078] In step A1, when the first user identity module dials successfully, detect the transmission quality of each APN.

[0079] In step A2, when there is an APN with abnormal transmission quality, determine a network anomaly and judge the type of network anomaly.

[0080] In step A3, when the type of network anomaly is a data plane anomaly, determine the state of the vehicle.

[0081] In step A4, when the state of the vehicle is a stopped state and the duration of the abnormal transmission quality reaches a first duration, control the second user identity module in the in-vehicle unit to initiate a data dial to the 5G mobile communication network.

[0082] In step A5, when the state of the vehicle is a driving state and the duration of the abnormal transmission quality reaches a second duration, control the second user identity module in the in-vehicle unit to initiate a data dial to the 5G mobile communication network.

[0083] In addition, in this application, if the first user identity module dials successfully, the transmission quality of each APN (Access Point Name) will still be detected.

[0084] Among them, the APN is a network setting used to connect a mobile device to a mobile network. Each network operator has its own APN settings and provides configuration information to users. The APN is a parameter recorded in the SIM card or inside the device, which tells the mobile device which network to connect to and how to connect to that network. By configuring the correct APN, the mobile device can obtain a data connection, thereby enabling Internet access, sending and receiving emails, using online applications, etc. Usually, when a new SIM card is inserted into a mobile device, the device will automatically detect and configure the correct APN settings.

[0085] When detecting the transmission quality of each APN, an instruction for testing the network connection status can be cyclically sent to the cloud service address of the 5G mobile communication network, and the return time of the response message of the instruction for testing the network connection status returned by the cloud service address of the 5G mobile communication network can be detected. When the time interval between sending the instruction for testing the network connection status and the return time of the response message is greater than a third duration, determine the APN with abnormal transmission quality. It is also possible to determine whether the transmission quality of the APN is normal through the packet loss rate of the uplink and downlink data of the network card corresponding to each APN. Specifically, detect the packet loss rate of the uplink and downlink data of the network card corresponding to each APN; when there is a network card with a packet loss rate reaching a preset packet loss rate, determine the APN with abnormal transmission quality.

[0086] When an APN with abnormal transmission quality appears, determine the network anomaly and judge the type of network anomaly; when the type of network anomaly is a data plane anomaly, determine the state of the vehicle; specifically, a data plane anomaly usually refers to problems such as weak signal, network congestion, and inability of individual software to connect to the network, etc.; when the state of the vehicle is a stopped state and the duration of the abnormal transmission quality reaches the first duration, control the second user identity module in the vehicle head unit to initiate a data dial-up to the 5G mobile communication network; when the state of the vehicle is a driving state and the duration of the abnormal transmission quality reaches the second duration, control the second user identity module in the vehicle head unit to initiate a data dial-up to the 5G mobile communication network. Specifically, if the duration of the abnormal transmission quality reaches a certain length, it is very likely that the area where the vehicle is located is not within the 5G network coverage of the operator corresponding to the first user identity module. If the vehicle is in a stationary state, it cannot enter the 5G network coverage of the operator corresponding to the first user identity module in a short time. If the vehicle is in a driving state, it may enter the 5G network coverage of the operator corresponding to the first user identity module in a short time. Therefore, in this application, the first duration is usually set shorter, such as 5 seconds, and the second duration is longer, such as 3 minutes, so as to reserve a certain time for the vehicle to re-enter the 5G network coverage of the operator corresponding to the first user identity module. Usually, the two identity modules in the vehicle head unit belong to different operators. When the location where the vehicle head unit is located is not within the 5G network coverage of the operator corresponding to the first user identity module, it may still be within the 5G network coverage of the operator corresponding to the second user identity module. Therefore, if the state of the vehicle is a stopped state and the duration of the abnormal transmission quality reaches the first duration, or if the state of the vehicle is a driving state and the duration of the abnormal transmission quality reaches the second duration, then control the second user identity module to attempt to initiate a data dial-up to the 5G mobile communication network.

[0087] In one embodiment, the above step A1 can be implemented as the following steps A11 - A12:

[0088] In step A11, circularly send an instruction for testing the network connection status to the cloud service address of the 5G mobile communication network, and detect the return time of the response message of the instruction for testing the network connection status returned by the cloud service address of the 5G mobile communication network;

[0089] In step A12, when the time interval between the issuance of the instruction for testing the network connection status and the return time of the response message is greater than the third duration, determine the APN with abnormal transmission quality.

[0090] In one embodiment, the above step A1 can be implemented as the following steps A13 - A14:

[0091] In step A14, the packet loss rate of the uplink and downlink data of the network card corresponding to each APN is detected;

[0092] In step A15, when there is a network card whose packet loss rate reaches the preset packet loss rate, the APN with abnormal transmission quality is determined.

[0093] In one embodiment, the determination method of dialing failure can be implemented as the following steps B1 - B2:

[0094] In step B1, when the vehicle is in a stationary state and the first subscriber identity module fails to dial successfully, a retry is performed;

[0095] In step B2, when the retry fails, it is determined that the dialing fails, and a static restart flag is set in the in - vehicle unit.

[0096] In one embodiment, the method can also be implemented as the following steps:

[0097] When the communication duration of the second subscriber identity module through the 5G mobile communication network reaches the third duration, or the vehicle changes from a stationary state to a moving state, the static restart flag is cleared.

[0098] In one embodiment, the method can also be implemented as the following steps:

[0099] When clearing the static restart flag, the first subscriber identity module in the in - vehicle unit is controlled to initiate a data dialing to the 5G mobile communication network again.

[0100] In this application, when the vehicle is in a stationary state, if the first subscriber identity module fails to dial successfully, a retry is performed. If the retry fails, it is determined that the dialing fails, and a static restart flag is set in the in - vehicle unit. This static restart flag is used to represent that the dialing has been retried and failed. And when this static restart flag exists, continuous retry can be prohibited to avoid wasting computing resources due to retries. When the communication duration of the in - vehicle unit through the second subscriber identity module connecting to the 5G network reaches the third duration, the static restart flag is cleared, which facilitates the first subscriber identity module in the in - vehicle unit to retry again. The time of this third duration can be relatively long, for example, 30 minutes, 1 hour, etc. And when the vehicle changes from a stationary state to a moving state, it is possible to re - enter the 5G coverage area set by the operator corresponding to the first subscriber identity module. Therefore, when the vehicle changes from a stationary state to a moving state, the static restart flag is also cleared to facilitate the first subscriber identity module in the in - vehicle unit to retry again. When clearing the static restart flag, the first subscriber identity module in the in - vehicle unit is controlled to re - attempt to connect to the 5G network.
