Abstract

A method, device, and storage medium for vehicle-to-arbitrary V2X communication, the method comprising: a server acquires a mapping relationship, the mapping relationship includes a mapping relationship between geographic location information and a pseudo-multicast address; The above mapping relationship, so that the V2X terminal determines the target pseudo-multicast address according to the current location information and the mapping relationship, and joins the multicast group corresponding to the target pseudo-multicast address. By adopting this solution, it is possible to ensure that the V2X terminal joins an appropriate multicast group under the premise of improving the security of the multicast group.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular to a method, device and storage medium for device-to-arbitrary D2X communication. Background technique [0002] In the field of Internet of Vehicles communication, Internet of Vehicles is used for intelligent information exchange and sharing between vehicles and anyone (such as people, vehicles, roads, backgrounds, etc.). Vehicle-to-infrastructure (V2I) communication, vehicle-to-network (V2N) communication, vehicle-to-cloud (V2C) communication, vehicle-to-people (V2P) communication, etc. Vehicle to X, V2X) communication interconnection scenarios. For example, in V2V communication, vehicles will periodically broadcast their own status information within a certain geographical range. In order to reduce the number of V2V messages and improve the range timeliness of V2V messages, multicast technology is now mainly used to achieve efficient transmission efficiency...
