Abstract

The embodiment of the invention discloses a V2X message transmission method, relates to the technical field of communication, and aims to solve the problem caused by the fact that an application layerof a terminal autonomously selects a communication interface for transmitting a V2X message. The method comprises the following steps that a terminal acquires a service identifier of a first V2X message; the terminal determines the communication interface of the first V2X message according to the corresponding relation between the service identifier of the V2X message and the communication interface and the service identifier of the first V2X message, wherein the first corresponding relation is shown in the specification; and the terminal sends the first V2X message through the communicationinterface of the first V2X message.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a method, device, and system for transmitting a vehicle to everything (V2X) message. Background technique [0002] In the vehicle to everything (V2X) communication system, there are many different types of V2X messages, such as: vehicle to vehicle (vehicle to vehicle, V2V) message, vehicle to person (vehicle to person, V2P) message, vehicle For network (vehicle to network, V2N) information, vehicle to infrastructure (vehicle to infrastructure, V2I) information, anti-collision information between vehicles, entertainment application information, navigation information for vehicle-to-vehicle interaction, etc. Quality of service (quality of service, QoS) requirements of these V2X messages may be different. Taking V2V messages and V2N messages as examples, V2V messages require low delay and high reliability in transmission, while V2N messages do not require ...
