Communication resource acquisition method, vehicle and base station

Abstract

The invention discloses a communication resource acquisition method, a vehicle and a base station, and relates to the technical field of communication. The method comprises the steps of analyzing at least two communication resource allocation messages to obtain an analysis result under the condition of determining that the at least two communication resource allocation messages are obtained within a preset duration, wherein the communication resource allocation messages include communication resource timestamps and to-be-used communication resources, the communication resource timestamp is a timestamp generated when the timestamp server signs the time of receiving the to-be-used communication resource by using a private key of the timestamp server, and the analysis result comprises a timestamp sorting result; according to the timestamp sorting result, selecting the target communication resources from the to-be-used communication resources, wherein the target communication resources are resources used when the current vehicle communicates with other devices in the Internet of Vehicles. Through the communication resource timestamp marked with the timestamp server private key signature, the current vehicle can obtain the communication resource meeting the requirement of the current vehicle, and the communication security between the vehicles is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method for acquiring communication resources, a vehicle and a base station. Background technique [0002] The Internet of Vehicles includes multiple vehicles. If there is a malicious base station in the Internet of Vehicles, the malicious base station will allocate the same communication resources to all vehicles that request communication resources from it, so that multiple vehicles will use the same communication resources for communication, which is easy to cause Serious resource occupation conflicts. [0003] When the legal base station in the Internet of Vehicles receives the communication message sent by multiple vehicles, the legal base station will demodulate the data transmission block (Transport Block, TB) in the communication message. Due to the interference of other messages with the same frequency, the calculated The signal to interference plus...

AI Technical Summary

Problems solved by technology

In a coordinated driving fleet, if a certain vehicle cannot receive the communication messages sent by other vehicles in the fleet, it will easily lead to an increase in the distance between the vehicle and other vehicles, which will affect the driving efficiency of the fleet; The distance between vehicles is lower than the preset distance threshold, which may easily lead to traffic accidents
