[0022] If a vehicle stays for a long time in a weak signal or no signal environment, such as an underground garage or remote area, the vehicle network may be unable to register due to weak or no signal.
[0023] In weak or no signal environments, vehicle terminals typically enter sleep mode to reduce power consumption. Sleep mode is an energy-saving mechanism that automatically enters a low-power state when the vehicle is stationary for an extended period and has no communication needs. However, to maintain network connectivity, vehicle terminals frequently search for the network while in sleep mode to ensure that once the signal is restored, the terminal can quickly reconnect to the network and resume normal communication functions. However, in prolonged weak or no signal environments, frequent network searches by vehicle terminals increase power consumption, resulting in excessive sleep power consumption.
[0024] Based on the above problems, an embodiment of the present application proposes a communication network management method, which helps to solve the problem of excessive sleep power consumption of vehicle-mounted terminals due to frequent network searches in weak signal or no signal environments.
[0025] Now combined Figure 1-Figure 2 The communication network management method provided in the embodiment of the present application is described.
[0026] Figure 1 A flow chart of a communication network management method provided in one embodiment of the present application specifically includes the following steps: Step S11: During the heartbeat packet wake-up period, network information, power mode information and vehicle status are obtained.
[0027] Specifically, the vehicle terminal wakes up at regular intervals and sends a heartbeat packet to the remote vehicle control platform (or server) to maintain a data connection and a persistent connection with the remote vehicle control platform. A heartbeat packet is a data packet sent by the vehicle terminal to the remote vehicle control platform during a scheduled wakeup, containing the wakeup command. This heartbeat packet wakeup mechanism prevents the vehicle terminal and the remote vehicle control platform from disconnecting due to prolonged periods of inactivity. It also verifies the remote vehicle control platform that the vehicle terminal is still active, ensuring that communication between the vehicle terminal and the remote vehicle control platform is maintained even in sleep mode, allowing the vehicle terminal to promptly respond to remote control commands from the remote vehicle control platform.
[0028] Optionally, the vehicle terminal will be awakened every 9 minutes and 30 seconds. During the awakening period, the vehicle terminal can obtain the vehicle's network information, power mode information, and vehicle status. Step S12: Determine whether the network registration is successful based on the network information. If the network registration is unsuccessful, dial up the network and start the timer to obtain the timing information.
[0029] Specifically, the network information includes a network registration status, which is one of a registered state (On Service) and an unregistered state (Out of Service). Whether the network registration is successful is determined based on the network information, including: if the network registration status is a registered state, the network registration is successful; or if the network registration status is an unregistered state, the network registration is unsuccessful.
[0030] In weak or no signal environments, or when the vehicle is experiencing network interference, network registration may fail. The vehicle terminal determines whether network registration is successful based on the network information it obtains. If network registration is unsuccessful, dial-up registration is performed. The dial-up registration process includes the following steps: the vehicle terminal first searches for an available network signal; upon finding an available network signal, it registers with the network and obtains access to network services; after completing network registration, it dials in to establish a communication link with the network, enabling data upload and download.
[0031] Furthermore, during the dial-up network registration process, a timer is synchronously started to time the network registration process and obtain timing information, which is used to represent the duration of the dial-up network registration process. By timing the dial-up network registration process, it is helpful to control the network registration time and prevent excessive network registration time from increasing power consumption.
[0032] In some embodiments, after dialing the network and starting the timer, the method provided by the present application further includes: if the timing information is greater than the preset time length, the timer is reset and the network search and registration module of the vehicle terminal is allowed to sleep.
[0033] By setting a preset time, the vehicle terminal dials up the network at a specified time. If the network registration time exceeds the preset time, it means that the vehicle terminal has not successfully registered with the network within the specified time. In this case, the vehicle terminal's network search and registration module is allowed to sleep. When the network search and registration module is dormant, the vehicle terminal will stop searching for the network, reducing dormant power consumption.
[0034] Optionally, the preset time is 2 minutes. The longer the time setting is, the higher the power consumption of the vehicle terminal. Setting the preset time to 2 minutes can meet the time requirement of the vehicle terminal from searching the network to registering the network, and can reduce power consumption.
[0035] It is understood that within two minutes, the vehicle terminal continuously obtains updated network information and loops through step S12, determining network registration based on the updated network information. If network registration is unsuccessful, a dial-up connection is performed, with the timer continuing to count. Optionally, if network registration is successful based on the updated network information, the timer is reset and the vehicle terminal's network search and registration module is allowed to sleep. If network registration is successful, indicating that the vehicle terminal has registered with the network, network search and registration can be stopped, reducing power consumption caused by frequent network searches.
[0036] Step S13, controlling the opening or closing of the network according to the network information, power mode information, vehicle status and timing information.
[0037] Specifically, the vehicle state is one of the vehicle awake state and the vehicle dormant state. In the present application, the vehicle terminal can control the opening or closing of the network in combination with network information, power mode information, vehicle state and timing information. When the vehicle is in a weak signal or no signal environment, the network search can be stopped by shutting down the network, thereby reducing dormant power consumption. And when the network is restored, the vehicle terminal searches the network normally and registers to the network under the heartbeat packet wake-up, thereby improving the vehicle's networking capability in a weak signal or no signal state, ensuring that the vehicle can quickly restore the network after leaving a weak signal or no signal environment, and improving the user experience.
[0038] It is understood that controlling the network on or off refers to controlling the network connection function of the vehicle's built-in communication module (such as 4G / 5G, Wi-Fi, etc.). The network connection function refers to the ability to exchange data with external networks (such as remote vehicle control platforms and cloud servers).
[0039] In some embodiments, the network is controlled to be turned on or off according to network information, power mode information, vehicle status and timing information, including: judging whether the vehicle-mounted terminal is in an operating state according to the power mode information; if the vehicle-mounted terminal is in an operating state, network registration is unsuccessful, the vehicle status is a vehicle-dormant state and the timing information is greater than a preset time length, then turning off the network; or if the vehicle-mounted terminal is in an operating state, network registration is unsuccessful, the vehicle status is a vehicle-dormant state and the timing information is less than or equal to a preset time length, then querying the network switch to judge whether the network is turned off, and if the network is turned off, then turning on the network.
[0040] Specifically, the Power Management System (PSM) refers to the different operating states of the vehicle's power management system, which determine the power supply and power consumption of each module in the vehicle. Power mode information typically includes the vehicle's current power supply status and the operating status of each module (such as TBOX operating information). Therefore, power mode information can be used to determine whether the vehicle terminal is in an operational state.
[0041] Then, through the above step S12, it is possible to determine whether the network registration is successful based on the network information. If the network registration is unsuccessful, the network registration is performed and the timer is started to obtain the timing information. If the vehicle terminal is in the running state, the network registration is unsuccessful, the vehicle status is the vehicle dormant state, and the timing information is greater than the preset time, the network is turned off; or if the vehicle terminal is in the running state, the network registration is unsuccessful, the vehicle status is the vehicle dormant state, and the timing information is less than or equal to the preset time, the network switch is queried to determine whether the network is turned off. If the network is turned off, the network is turned on. During the cyclic network search process, the network may be turned off due to a network registration timeout. Therefore, it is necessary to query the network switch to determine whether the network is turned off. If the network is turned off, the network is turned on.
[0042] In some embodiments, if the vehicle terminal is in operation, network registration is unsuccessful, and the vehicle is in a vehicle awake state, the network switch is queried to determine whether the network is closed. If the network is closed, the network is turned on.
[0043] Figure 2 A flow chart of a communication network management method provided in another embodiment of the present application is shown as follows: Figure 2 As shown, during the heartbeat packet wake-up period, the registration network processing flow and the network weak signal processing flow are performed synchronously.
[0044] The network registration process includes obtaining network information and determining whether network registration is successful. If network registration is unsuccessful, dialing up the network and timing the dialing process are performed, and the resulting timing information is synchronized with the network weak signal processing process. If network registration is successful, the timer is cleared and the network search and registration module is allowed to sleep. The timing information (network registration time) obtained after dialing up the time is then evaluated to determine whether the network registration time is greater than 2 minutes. If so, the timer is cleared and the network search and registration module is allowed to sleep. If the network registration time is less than 2 minutes, the process of determining whether network registration is successful, dialing up the network, and timing the dialing process is repeated.
[0045] The weak network signal processing process includes obtaining network information, power mode information, and vehicle status, determining whether the vehicle terminal is in operation, determining whether network registration is successful, determining whether the vehicle status is in sleep mode, and determining whether the network registration time is greater than 2 minutes. If the vehicle terminal is in operation, network registration is unsuccessful, the vehicle status is in sleep mode, and the timing information is greater than 2 minutes, the network is shut down; or if the vehicle terminal is in operation, network registration is unsuccessful, the vehicle status is in sleep mode, and the timing information is less than or equal to 2 minutes, the network switch is queried to determine whether the network is shut down. If the network is shut down, the network is turned on. Or if the vehicle terminal is in operation, network registration is unsuccessful, and the vehicle status is in wake-up mode, the network switch is queried. If the network is shut down, the network is turned on.
[0046] In this application, during the heartbeat packet wake-up period, network information, power mode information and vehicle status are obtained; based on the network information, it is determined whether the network registration is successful. If the network registration is unsuccessful, the network is dialed and registered, and a timer is started to obtain timing information; the network is turned on or off according to the network information, power mode information, vehicle status and timing information, so that during the heartbeat packet wake-up period, the vehicle terminal dials and registers within a preset time period, and can control the network on or off according to the network information, power mode information, vehicle status and timing information. When the network is closed, no network search is performed, which helps to solve the problem of excessive power consumption in dormancy due to frequent network searches in a weak signal or no signal environment. And when the network is restored, the vehicle terminal searches and registers to the network normally under the heartbeat packet wake-up, improving the vehicle's networking capability in a weak signal or no signal state, ensuring that the vehicle can quickly restore the network after leaving a weak signal or no signal environment, and improving the user experience.
[0047] Based on the same idea, the embodiment of the present application also provides a communication network management device, such as Figure 3 This is a schematic diagram of the structure of a communication network management device provided in an embodiment of the present application. The device 30 mainly includes: The acquisition module 31 is used to obtain network information, power mode information and vehicle status during the heartbeat packet wake-up period; The judgment module 32 is used to judge whether the network registration is successful according to the network information. If the network registration is unsuccessful, the network registration is dialed and a timer is started to obtain timing information. The control module 33 is used to control the opening or closing of the network according to network information, power mode information, vehicle status and timing information.
[0048] In one possible implementation, the network information includes a network registration status, which is one of a registered state and an unregistered state. The judgment module 32 can also be used to: if the network registration status is a registered state, the network registration is successful; or if the network registration status is an unregistered state, the network registration is unsuccessful.
[0049] In one possible implementation, the judgment module 32 may also be used to: after dialing the network and starting the timer, if the timing information is greater than the preset time, reset the timer and allow the network search and registration module of the vehicle terminal to sleep.
[0050] In one possible implementation, the judgment module 32 may also be configured to: if the network registration is successful, reset the timer and allow the network search and registration module of the vehicle-mounted terminal to sleep.
[0051] In one possible implementation, the vehicle state is one of a vehicle awake state and a vehicle dormant state, and the control module 33 may further be used to: determine whether the vehicle terminal is in an operating state according to the power mode information; If the vehicle terminal is in operation, network registration is unsuccessful, the vehicle is in sleep mode, and the timing information is greater than the preset time, the network will be shut down; or If the vehicle terminal is in operation, network registration is unsuccessful, the vehicle is in sleep mode, and the timing information is less than or equal to the preset duration, the network switch is queried to determine whether the network is turned off. If the network is turned off, the network is turned on.
[0052] In one possible implementation, the control module 33 can also be used for: if the vehicle terminal is in operation, network registration is unsuccessful and the vehicle state is the vehicle awake state, then query the network switch to determine whether the network is closed, and if the network is closed, then turn on the network.
[0053] In one possible implementation, the preset duration is 2 minutes.
