Device to Device (D2D) resource distribution method of Internet of Vehicles terminal and related device

Abstract

The invention discloses a Device to Device (D2D) resource distribution method of an Internet of Vehicles terminal and a related device which are used to achieve D2D resource distribution of a terminal in an Internet of Vehicles system and improve use efficiency of a wireless resource, resource distribution efficiency and resource updating efficiency. The method comprises the following steps: a D2D resource control entity receives a first signal sent by a terminal through a base station, wherein the first signal at least carries position information of the terminal; and, according to the position information of the terminal and locally saved D2D resource occupied information, the D2D resource control entity allocates an idle D2D resource for the terminal and sends indication information of the allocated D2D resource to the terminal through the base station, wherein the D2D resource occupied information comprises the position information of the terminal of the allocated D2D resource and occupied D2D resource information thereof.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a device-to-device (D2D) resource allocation method for an Internet of Vehicles terminal and related devices. Background technique [0002] The active and safe Internet of Vehicles communication system for vehicles is based on wireless communication technology to obtain vehicle and road information, and realizes intelligent coordination and cooperation between vehicles and infrastructure through vehicle-vehicle and vehicle-road information interaction and sharing, so as to optimize the use of system resources and improve road safety. Traffic safety, the purpose of alleviating traffic congestion. [0003] The Internet of Vehicles communication system for vehicle active safety has high requirements on communication delay, so the self-organizing network technology of short-distance communication is generally used. At present, in the field of Internet of Vehicle...

Problems solved by technology

[0007] For 3GPPD2D technology, the in-band part of the allocated spectrum is mainly used. A small number of terminals will activate D2D services, and the terminals of the Internet of Vehicles need to allocate spectrum resources. The characteristics of 3GPPD2D technology are different from the requirements of Internet of Vehicles applications. The wireless resource allocation method of the terminal in the medium cannot directly learn from the wireless resource allocation method of the terminal in the 3GPPD2D technology
