多接入边缘计算技术与车联网的融合应用

Application of Multi-Access Edge Computing in connected vehicles

多接入边缘计算是5G网络架构中非常重要的一个环节,主要面向需要更低时延和更高带宽业务的场景。车联网是对时延和可靠性要求都非常高的典型业务场景,将C-V2X业务部署在MEC平台上,应用数据的时延将显著降低,同时可以缓解边缘侧的计算和存储压力,避免大量数据通过网络回传带来的拥塞,提供本地的高质量服务。对MEC在车联网中的典型应用场景、服务流程和商业模式进行了阐述,为MEC与V2X融合产业发展提出了建议。

Multi-Access Edge Computing(MEC)is an indispensable part of 5G network architecture,which can meet the application scenarios with lower delay and higher bandwidth requirements.The connected vehicle is a typical scenario with low delay and high reliability requirements.Deploying C-V2X service on MEC platform can reduce the end-to-end data transmission delay,relieve the calculation and storage pressure of terminal or roadside intelligent facilities,reduce the network load caused by massive data return,and provide high-quality services with local characteristics.This paper focuses on the typical application scenarios and service processes of MEC in ICVs,sorts out the current situation and business model of the industry,and puts forward suggestions for the development of MEC and V2X integrated industry.
