摘要
目前实现车联网业务有PC5和Uu两种技术方案,其中PC5方案中的RSU主要基于DSRC技术进行通信,其通信范围相对有限且部署成本高,难以实现规模部署。与5G网络相比,DSRC的通信距离和稳定性可能无法满足大规模车联网应用的需求,尤其是在城市复杂交通环境中。本文基于车联网业务场景,论述基于5G技术的车联网网络方案及实现流程,并在中国移动5G组网架构下完成应用场景的测试与验证。结果表明在5G组网构架下,V2X业务的RTT时延达到50毫秒可靠性达到99%,满足车联网业务需求。
At present,there are two technical solutions for implementing vehicle networking services:PC5 and Uu.The RSU in the PC5 solution is mainly based on DSRC technology for communication,which has a relatively limited communication range and high deployment costs,making it dificult to achieve large-scale deployment.Compared with 5G networks,the communication distance and stability of DSRC may not meet the needs of large-scale connected vehicle applications,especially in complex urban traffic environments.This article is based on the business scenario of the Internet of Vehicles,discussing the network solution and implementation process of the Internet of Vehicles based on 5G technology,and completing the testing and verification of the application scenario under the 5G network architecture of China Mobile.The results show that under the 5G networking architecture,the RTT latency of V2X services reaches 50ms and the reliability reaches 99%,meeting the requirements of vehicle networking services.
