Problems solved by technology

[0009] The purpose of the present invention is to provide a method for controlling resource allocation of DSRC, a base station and a vehicle communication terminal, aiming to solve the problem that the vehicle communication terminal in the prior art adopts DSRC technology, because the physical layer of DSRC has a variable frame length, thus causing Resource efficiency is low. In addition, the way of competition leads to the problem that in the scenario of high-density vehicles, the transmission delay cannot meet the needs of vehicle safety communication.

Abstract

The invention is applicable to the vehicle network field, and provides a method for controlling DSRC resource allocation, a base station and a vehicle communication terminal. The vehicle communication terminal includes a dedicated short-range communication DSRC module and a cellular mobile communication module, the DSRC module and the cellular mobile communication module are connected through an interface; the DSRC module is used for wireless connection with DSRC modules in other vehicle communication terminals, Realize wireless communication between vehicles; the cellular mobile communication module is used to receive the control message of the resource allocation of the base station to the DSRC module, and forward it to the DSRC module through the interface, and forward the received DSRC module to the cellular mobile communication module through the interface The communication module receives the resource allocation request message sent by the cellular mobile communication module to the base station. The invention can realize the base station to control the resources of the DSRC, flexibly adjust the configuration parameters of the resources, realize the congestion control of the DSRC, and adjust the configuration according to the scene.

Description

technical field [0001] The invention belongs to the field of vehicle networks, and in particular relates to a method for controlling resource allocation of dedicated short-range communications (Dedicated Short Range Communications, DSRC), a base station and a vehicle communication terminal. Background technique [0002] The vehicle network, that is, the vehicle interconnection network, vehicles in the vehicle network are equipped with vehicle communication terminals, and the vehicle communication terminals installed on the vehicles use the mobile communication network to realize the communication between vehicles and realize the interconnection of vehicles. The United States has developed a vehicle communication terminal using DSRC technology. After the vehicle is installed with a vehicle communication terminal using DSRC technology, wireless communication between vehicles can be realized. [0003] The frequency point used by DSRC technology is 5.9G spectrum. The characteris...
