Description

Switching method, device, equipment and storage medium of vehicle-mounted network Technical Field The present application relates to the field of network technologies, and in particular, to a method, an apparatus, a device, and a storage medium for switching a vehicle-mounted network. Background With the rapid development of intelligent network-connected automobiles, the dependence of vehicle-mounted terminals on continuous and reliable mobile communication capability is increasingly deepened. The embedded subscriber identity module (Embedded Subscriber Identity Module, eSIM) is gradually replacing the traditional entity subscriber identity module because of the advantages of being capable of remotely configuring the subscription of an operator, saving physical space and the like, and becomes a key component for realizing the networking of vehicles. Through the embedded user identity module, the vehicle can access to a cellular mobile network, and various internet of vehicles services such as navigation, entertainment, remote diagnosis and automatic driving are supported. In the prior art, in order to realize network connection of a vehicle in a cross-border driving scene, an embedded user identity module subscription configuration file of a leading operator is preset on the vehicle. When the vehicle travels to other countries or regions, network communication of the vehicle is realized depending on a roaming cooperation agreement pre-agreed between the vehicle home operator and the international operator. But because the vehicle still needs to route communication data through the home operator after crossing the border, high roaming costs are incurred and network quality of service is generally inferior to local direct access. Also, long-term international roaming may violate regulations in the destination country regarding data localization or permanent roaming restrictions, resulting in interruption of communication services. It should be noted that the information disclosed in the background section of the present application is only for enhancement of understanding of the general background of the present application and should not be taken as an admission or any form of suggestion that this information forms the prior art that is well known to a person skilled in the art.

In a first aspect, an embodiment of the present application provides a method for switching a vehicle-mounted network, which is applied to a system including a vehicle-mounted terminal and a cloud control platform, where the method includes: The vehicle-mounted terminal acquires fusion state information of a vehicle and sends the fusion state information to the cloud control platform, wherein the fusion state information is used for indicating that a cross-border event occurs or is about to occur in the vehicle; the cloud control platform determines a target network operator from at least one candidate network operator according to a preset multidimensional decision strategy based on the received fusion state information; the cloud control platform sends a network switching instruction associated with the target network operator to the vehicle-mounted terminal; And the vehicle-mounted terminal executes the switching operation of the operator configuration file of the embedded user identity module according to the network switching instruction so as to access the network of the target network operator. In the embodiment of the application, the vehicle-mounted terminal acquires and reports the fusion state information for indicating the occurrence or impending cross-border event of the vehicle in real time, so that the cloud control platform can timely sense the cross-border intention of the vehicle. And the cloud control platform intelligently selects an optimal target network operator in the target area from the candidate network operators according to a preset multidimensional decision strategy, and remotely schedules the vehicle-mounted terminal by issuing a network switching instruction. The vehicle-mounted terminal executes the switching operation of the operator configuration file of the embedded user identity module according to the switching operation, and finally the vehicle is directly accessed to the local optimal network after crossing the environment, so that the dependence on international roaming is effectively avoided. Therefore, the embodiment of the application systematically reduces the cross-border communication cost generated by depending on
