Abstract

The embodiment of the invention discloses a direct link establishment method and related equipment. The method comprises the following steps: first access network equipment sends first indication information to first terminal equipment, wherein the first indication information is used for indicating the first terminal device to trigger establishment of a direct connection link flow. According to the invention, the electric quantity of the terminal equipment and wireless network resources can be saved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for establishing a direct link and related equipment. Background technique [0002] The information exchange between the vehicle and the outside world (Vehicle to X, referred to as V2X, also known as vehicle to everything) is the key technology of the future intelligent transportation system, and the main research is based on the 3rd Generation Partnership Project (3GPP) communication The vehicle data transmission scheme of the protocol. V2X communication includes Vehicle to Vehicle (V2V for short) communication, Vehicle to Infrastructure (V2I for short) communication and Vehicle to Pedestrian (V2P for short) communication. V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-vehicle entertainment information, etc. At the same time, the V2X communication method can also be...
