Abstract

The embodiment of the invention discloses a method, device and system for establishing a PC5 link, relates to the field of communication technology, and is used to solve the problem that the prior art cannot better establish a PC5 link between UEs. The method includes: the first UE sends a direct communication request message, the direct communication request message carries the identifier of the first UE, and the direct communication request message is used to request establishment of a PC5 link; the first UE receives the direct communication message sent by the second UE An acceptance message, where the direct communication acceptance message carries the identity of the second UE, and the direct communication acceptance message is used to accept establishing a PC5 link with the first UE. This solution is specifically applied in the scenario of establishing a PC5 link between UEs.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a PC5 link establishment method, device and system. Background technique [0002] With the continuous development of communication technology, there have been information exchange (Vehicle to X, V2X) technologies between vehicles and everything, such as Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P) and Vehicle to Pedestrian (V2P). Communication and interaction of infrastructure (Vehicle to Infrastructure, V2I). Wherein, V2X services such as V2V and V2P may be transmitted through a PC5 interface between a user equipment (User Equipment, UE) and the UE. [0003] Currently, taking the transmission of 5G NR-based V2X services between UE 1 and UE 2 through the PC5 interface as an example, before transmitting the V2X services between UE 1 and UE2 through the PC5 interface, a PC5 link needs to be established between UE 1 and UE 2 road. S...
