The network state information of the T-BOX is displayed through a vehicle-mounted device (IVI), meanwhile, in order to enhance maintainability of the T-BOX, an interface for restarting the T-BOX by the vehicle-mounted device is added on a vehicle-mounted device and a T-BOX USB communication protocol, and the T-BOX can be restarted when necessary (for example, the T-BOX displays a scene that a signal exists but the Internet cannot be accessed). The car machine management module mainly receives information from a car machine, processes and analyzes the information, calls other target sub-modules according to an analysis result, and the modem management module manages information from the 5G \4G module and calls related interfaces of the module, such as dialing. Modems are the 5G \4Gmodules, usually high-pass modules, huacheng modules, MTK modules, etc., which are integrated by the T-BOX manufacturer for their upstream calls.

According to some embodiments, as shown in fig. 2, fig. 2 shows a flowchart of steps performed from the perspective of a T-BOX apparatus side, and the present application provides a network management method of a vehicle T-BOX apparatus, the method being performed in the T-BOX apparatus, the method comprising: step 201, receiving a network restart request sent by a vehicle machine through a network restart interface; step 202, responding to the network restart request, and judging whether the T-BOX device is in a remote upgrading state or a remote control state; step 203, if the T-BOX device is not in the remote upgrade state and is not in the remote control state, sending a notification message for executing a network restart action to the in-vehicle machine, and triggering to execute the network restart action after a first preset time.

Based on the above embodiment, in step 201, the network restart interface is: and on the vehicle machine and the T-BOX USB communication protocol, the added vehicle machine restarts the T-BOX interface. The network restart interface is an interface of a software layer. The T-BOX device receives a network restart request sent by the vehicle machine through a network restart interface.

Further, in step 202, after receiving the network restart request sent by the vehicle, the T-BOX device determines whether itself is in a remote upgrade state or a remote control state, and then replies a response to the network restart request to the vehicle.

Further, in step 203, if the T-BOX device is not in the remote upgrade state and is not in the remote control state, sending a notification message for performing a network restart action to the in-vehicle machine, and triggering to perform the network restart action after a first preset time. The first preset time can be set according to actual requirements, in some embodiments, the first preset time is set to 3 seconds, namely, notification information for executing network restart action is sent to the car machine, and the network is restarted after 3 seconds of delay, so that the car machine can receive a response of a request command sent by the T-BOX device and then restart the car machine.

The T-BOX is an internet access channel in a vehicle, the traditional T-BOX cannot directly interact with a user, when the T-BOX fails to be networked due to network environment problems, for example, a 5G signal similar to a mobile phone cannot be recovered after falling to 2G, or a network side directly issues an rejection code to prevent the T-BOX from accessing the network, according to a 3GPP protocol, the T-BOX needs to be restarted under certain specific conditions to allow communication to be recovered, if the user does not have the channel to restart the T-BOX, the T-BOX can be restarted only at a timing or under a triggering condition set inside the T-BOX, and user experience is influenced. Meanwhile, the T-BOX is restarted differently from a mobile phone which is an independent individual, and the T-BOX is restarted while the whole vehicle environment and the communication condition with other ECUs are considered. The method and the device effectively solve the problem that the user does not restart the T-BOX channel by adding the network restart interface.

Based on the above embodiment, as shown in fig. 7, fig. 7 shows an interaction timing diagram of the car machine and the T-BOX.

In step 701, firstly, after the car machine is normally connected with the T-BOX through the USB, the car machine and the T-BOX can establish Socket connection.

In step 702, after Socket connection, the car machine sends a handshake request to the T-BOX.

In step 703, the T-BOX sends a handshake response to the car machine.

In step 704, after the handshake between the car machine and the T-BOX is completed, the car machine sends a heartbeat request to the T-BOX. Wherein, the car machine sends a heartbeat request every 3 seconds.

In step 705, the T-BOX sends a heartbeat response to the car machine after receiving the heartbeat request from the car machine. And if the heartbeat response is not received within 3 seconds, the vehicle machine sends the heartbeat request to the T-BOX again. And when the vehicle machine retries twice and does not receive the heartbeat response of the T-BOX twice, the prompt response fails. The reasons include that the T-BOX does not send a heartbeat response, or the T-BOX does not receive a heartbeat request, or the T-BOX sends a heartbeat response to the car machine, but the car machine does not receive the heartbeat response, and the like.

In step 706, after the car machine keeps receiving the heartbeat response, the car machine sends a network restart request to the T-BOX. And if the vehicle machine does not receive the restart response within 3 seconds after sending the network restart request to the T-BOX, the vehicle machine resends the network restart request to the T-BOX. And when the vehicle machine does not receive the restarting response of the T-BOX after the vehicle machine retries twice, the prompt response fails.

In step 707, the T-BOX sends a network restart response to the car machine. And the T-BOX sends a network restart response to the vehicle machine, and controls self restart after delaying for 3 seconds so as to ensure that the vehicle machine can receive the restart response.

According to some embodiments, after maintaining the Socket connection with the car machine, the method further comprises: periodically acquiring network data information from a network; and reporting the network data information to the vehicle machine.

Based on the above embodiments, as shown in fig. 6, fig. 6 shows a car machine network status query flowchart.

In step 601, firstly, after the car machine is normally connected with the T-BOX through the USB, the car machine and the T-BOX can establish Socket connection.

In step 602, the vehicle machine and the T-BOX perform authentication and certification to prevent the vehicle from being connected by mistake.

In step 603, the car machine sends a handshake request to the T-BOX.

In step 604, the T-BOX sends a handshake response to the car machine.

In step 605, please refer to 1,T-BOX, the car management module periodically sends a request for obtaining network state information to the modem management module, the modem management module returns the network state information to the car management module after obtaining the network state information from the modem, and the car management module reports the network state information to the car to complete network state query after receiving the network state information sent by the modem management module.

According to some embodiments, the method further comprises: and if the T-BOX device is in a remote upgrading state or a remote control state, sending notification information of network restart failure to the vehicle machine.

Based on the above-described embodiment, when the vehicle is in the remote upgrade state or in the remote control state, the network is not allowed to be restarted, so that the remote control is stabilized, and the remote installation package download upgrade is stabilized.

According to other embodiments, from a vehicle-side perspective, the present application provides a network management method for a vehicle T-BOX apparatus, the method being performed at a vehicle machine, the method comprising: step 301, after a Socket connection with the car machine is maintained, sending a network restart request to a T-BOX device through a network restart interface to trigger the T-BOX device to execute a network restart action; and step 302, if the notification information for executing the network restarting action sent by the T-BOX device is not received within the second preset time, repeatedly executing the step of sending the network restarting request to the T-BOX device through the network restarting interface until the notification information for executing the network restarting action sent by the T-BOX device is received within the second preset time within the first preset repetition times.

Based on the above embodiment, as shown in fig. 3, in step 301, after a Socket connection between the T-BOX device and the car machine is maintained, the car machine sends a network restart request to the T-BOX device through a network restart interface to trigger the T-BOX device to execute a network restart action. And the vehicle machine informs the T-BOX to restart through a USB command.

In step 302, if the notification information for executing the network restart action sent by the T-BOX device is not received within a second preset time, the step of sending a network restart request to the T-BOX device through the network restart interface is repeatedly executed until the notification information for executing the network restart action sent by the T-BOX device is received within the second preset time within a first preset repetition number. In some embodiments, the first preset repetition time is two times, the second preset time is 3 seconds, if the car machine does not receive the response of the T-BOX device within 3 seconds, the car machine resends the notification, the maximum retry time does not exceed two times, and if no response still exists after two times, the request is prompted to fail, and the process is ended. After receiving the restart command sent by the car machine, the T-BOX gives a response first, and then restarts itself after delaying for 3 seconds (so that the car machine can receive the response of sending the request command).

According to some embodiments, before maintaining a Socket connection with the car machine, the method further comprises: after the Socket connection with the car machine is established for the first time, a handshake request sent to the T-BOX device is received, and a handshake response sent by the T-BOX device is received; after handshake with the T-BOX device, periodically sending heartbeat requests to the T-BOX device, and receiving heartbeat responses sent by the T-BOX device so as to maintain Socket connection with the car machine.

Further, after sending the heartbeat request to the T-BOX apparatus, the method further comprises: if the heartbeat response sent by the T-BOX device is not received within third preset time, the step of sending the heartbeat request to the T-BOX device is repeatedly executed until the heartbeat response sent by the T-BOX device is received within the third preset time within second preset repetition times.

Based on the above embodiment, as shown in fig. 7, fig. 7 shows an interaction timing diagram of the car machine and the T-BOX.

In step 701, firstly, after the car machine is normally connected with the T-BOX through the USB, the car machine and the T-BOX can establish Socket connection.

In step 702, after Socket connection, the car machine sends a handshake request to the T-BOX.

In step 703, the T-BOX sends a handshake response to the car machine.

In step 704, after the handshake between the car machine and the T-BOX is completed, the car machine sends a heartbeat request to the T-BOX. Wherein, the car machine sends a heartbeat request every 3 seconds.

In step 705, the T-BOX sends a heartbeat response to the car machine after receiving the heartbeat request from the car machine. In some embodiments, the third preset time is set to 3 seconds, and if the car machine does not receive the heartbeat response within 3 seconds, the car machine sends the heartbeat request to the T-BOX again. And after the vehicle machine retries to reach the second preset repetition number, the heartbeat response is still not received, and the response failure is prompted. In some embodiments, the second predetermined number of repetitions is two, and the prompt response fails if the car machine resends the T-BOX twice and neither of the two times receives the heartbeat response of the T-BOX. The reasons include that the T-BOX does not send a heartbeat response, or the T-BOX does not receive a heartbeat request, or the T-BOX sends a heartbeat response to the car machine, but the car machine does not receive the heartbeat response, and the like.

In step 706, after the car machine keeps receiving the heartbeat response, the car machine sends a network restart request to the T-BOX. And if the vehicle machine does not receive the restart response within 3 seconds after sending the network restart request to the T-BOX, the vehicle machine resends the network restart request to the T-BOX. And when the vehicle machine does not receive the restarting response of the T-BOX after the vehicle machine retries twice, the prompt response fails.

In step 707, the T-BOX sends a network restart response to the car machine. And the T-BOX sends a network restart response to the vehicle machine, and controls self restart after delaying for 3 seconds so as to ensure that the vehicle machine can receive the restart response.

According to some embodiments, the sending a network restart request to the T-BOX apparatus through the network restart interface includes: when the operation of network restarting action executed by a T-BOX device triggered by a user is monitored, sending a confirmation prompt to the user; and when the confirmation operation triggered by the user and aiming at the confirmation prompt is monitored within the fourth preset time, sending a network restart request to the T-BOX device through a network restart interface.

Based on the above embodiment, the fourth preset time may be set according to actual requirements.

When the user selects to restart the T-Box, in order to prevent misoperation, a prompt Box is popped up to be confirmed by the user. The vehicle machine sends a restart command to the T-Box only after the user confirms again; when the handshake for reestablishing the USB connection is completed, the T-Box can be prompted to restart, the restart is completed only after the restart completed by the user instruction is received, and the prompt is not required to be generated when the vehicle machine and the T-BOX are automatically restarted (such as internal timing restart) in the vehicle ignition starting stage.

Sending confirmation prompt to the user can prevent the user from pressing wrong keys, when the user presses the wrong keys, the network restarting action can be cancelled through the confirmation prompt, and when the user does not press the wrong keys, the network restarting action can be confirmed again.

The T-BOX internal processing logic is described below in more detail in a flow chart, as shown in fig. 8, and fig. 8 shows a T-BOX internal processing logic diagram 800.
