面向车联网的MEC跨域协同技术研究

Research on technology of cross-domain collaboration based onMEC for Internet of Vehicles

车联网跨域协同技术是多接入边缘计算(Multi-Access Edge Computing, MEC)和蜂窝车联网(Cellular Vehicle to Everything, C-V2X)融合场景中的重点研究内容,涉及到安全类、效率类、协作类、视频类、信息服务类跨域协同交互场景,每类场景都涉及MEC跨域流程及跨域过程中的上下文规范。目前国际上面向车联网的MEC跨域协同技术处于起步发展阶段,ETSI、5GAA等组织尚未制定比较完善的国际标准。以当前主流车联网边缘计算系统架构为基础,着重开展各类车联网场景应用层基于MEC的跨域需求、交互迁移流程及上下文规范等研究。

The technology of cross-domain collaboration based on MEC for Internet of Vehicles(IoV)is the key research point in the integration scenario of MEC-based C-V2X systems.The scenarios mainly include security,efficiency,collaboration,video,and information services.Each scenario involves processes and context specification information in the cross-domain collaborative interaction.At present,the technology of cross-domain collaboration based on MEC for IoV is in the early stage of development internationally,and organizations such as ETSI and 5GAA have not established corresponding and relatively complete international standards.Based on the mainstream edge computing system architecture of IoV,this paper focuses on the research of cross-domain requirements,interaction migration process and context specification based on MEC for application layers of IoV scenarios.
