基于LTE-V2X的大规模通信场景网络层性能测试与分析

Performance Test and Analysis of Network Layer in Large-scale Communication Scenario Based on LTE-V2X

随着车联网的大规模部署和商业化在即,LTE-V2X在实际场景中的通信性能将会直接影响到车联网产业发展以及交通安全。目前车联网通信性能测试主要是以小规模部署的通信环境为主,缺少在实际环境中对LTE-V2X通信系统的大规模流量的压力测试。基于“新四跨”标准环境,通过模拟车辆密集交通场景,对LTE-V2X终端网络层性能指标进行测量,验证其在负载压力下的通信性能,为LTE-V2X技术商用提供了可靠的试验数据。

With the large-scale deployment and commercialization of the Internet of vehicles approaching,the communication performance of LTE-V2X in the actual scene will directly affect the development of the Internet of vehicles industry and traffic safety.At present,the communication performance test of Internet of vehicles is mainly based on the communication environment of small-scale deployment,and there is a lack of pressure test on the large-scale flow of LTE-V2X communication system in the actual environment.Based on the“New Four Together”standard environment,it measures the performance index of LTE-V2X terminal network layer by simulating the vehicle intensive traffic scene,verifies its communication performance under load pressure,and provides reliable test data for the commercial use of LTE-V2X technology.
