Abstract

The invention provides a vehicle communication D2D discovery method, a device and a terminal. The vehicle communication D2D discovery method is suitable for the terminal and comprises the steps that a transmission performance requirement met by a service type corresponding to a vehicle communication service is acquired; according to the transmission performance requirement, the fact that the vehicle communication service has delay constraints is determined; and pre-registration is carried out on a network side entity, and / or a pre-allocation transmission resource scheduling mechanism is used, and / or the identification mapping information of the network-side entity is pre-acquired, so as to reduce interaction with the network-side entity in a D2D discovery process. According to the technical scheme provided by the invention, in the D2D discovery process of the terminal, interaction with the network-side entity is minimized; the delay of the D2D discovery process is effectively shortened; and V2X short delay transmission is supported.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a D2D discovery method for vehicle communication, and a D2D discovery method for vehicle communication. Background technique [0002] At present, the Internet of Vehicles (Internet of Vehicles), as an important technology that can be supported by 3G and 4G networks, has gradually been continuously developed. Based on the traditional cellular network architecture, part of the Internet of Vehicles applications can be realized, mainly V2I (Vehicle to Infrastructure, vehicle-to-road communication). Then, more vehicle-to-vehicle scenarios such as V2V (Vehicle to Vehicle, vehicle-to-vehicle communication), especially involving services such as emergency collision avoidance, require very short delays, so traditional cellular network technologies cannot support them. Therefore, the Internet of Vehicles technology with the help of Device-to-Device (D2D) technology is regar...
