Abstract

The embodiment of the invention provides a V2X message sending method, device and system, and relates to the field of Internet of Vehicles. The method comprises: a terminal obtaining first configuration information, and the first configuration information being used for determining a first transmission resource pool; determining the first transmission resource pool according to the first configuration information; when it is determined that a predetermined condition is met, selecting a first transmission resource in the first transmission resource pool by using a first transmission resource acquisition mode; and sending the V2X message by using the first transmission resource. Due to the fact that the speed of the first transmission resource obtaining mode is high when the transmission resources are selected, it is guaranteed that the V2X message can be normally transmitted under the specific sending scene when the preset condition is met.

Description

technical field [0001] Embodiments of the present invention relate to the field of Internet of Vehicles, and in particular, to a V2X message sending method, device and system. Background technique [0002] In the intelligent transportation system (Intelligent Transportation System, ITS), through vehicle to vehicle (Vehicle to Vehicle, V2V) communication, or vehicle and roadside infrastructure (Vehicle to Infrastructure, V2I) communication, or between vehicles and pedestrians (Vehicle to Pedestrian, V2P) communication, or vehicle and network (Vehicle to Network, V2N) communication to obtain various information about traffic in a timely manner, these communication methods can be collectively referred to as vehicle to X, V2X) communication. X is the collective term for vehicles, roadside infrastructure, pedestrians, and networks. [0003] When a V2X message is transmitted through a Long Term Evolution (Long Term Evolution, LTE) technology, two user equipments (User Equipment, ...
