Method, device and system for distributing resources

Abstract

Embodiments of the present invention provide a method, a device and a system for distributing resources, in order to solve the problems that a conventional D2D (Device-to-Device) resource distribution scheme cannot fully utilize D2D link resources and has a poor inter-area interference coordination capability. The method comprises the steps of: transmitting a resource distribution request carrying current position information of vehicle terminals to a D2D resource control entity; receiving a D2D link resource distributed by the D2D resource control entity, wherein the D2D link resource is determined by the D2D resource control entity according to the current position information and related information of each vehicle terminal within an information acquisition area, the related information comprises the current position information of each vehicle terminal and used D2D link resource information, and the information acquisition area comprises a resource management area of the D2D resource control entity and an area which is at least within a preset reuse distance of the D2D link resource outside of the resource management area.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource allocation method, device and system. Background technique [0002] The active and safe Internet of Vehicles communication system for vehicles is based on wireless communication technology, which obtains 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. The purpose of improving road traffic safety and alleviating traffic congestion. [0003] The above-mentioned IoV communication system has high requirements on time delay. Although the existing self-organizing network technology using short-distance communication can meet the time delay requirements of the IOV communication system, it has low communication link efficiency and difficult expansion of communica...
