5G 无线通信网络的大规模落地建设,促进 C-V2X 的应用场景向着更加多样化的方向发展。以高清视频、AR/VR为代表的大带宽业务给竖井式网络架构带来极大的传输和处理压力,同时以超高可靠低时延为特征的交通安全类业务对网络性能提出了严苛的要求。转发面功能下沉和MEC(multiple access edge computing)服务本地化处理,可在车联网场景中实现数据的短回路传输,降低了端到端时延,从而满足车联网的业务需求。深入探索MEC与车联网场景的深度融合,详细分析了MEC的网络架构、车联网场景中MEC的部署以及MEC在应用中的关键技术和挑战,并给出MEC与C-V2X(cellular-vehicle to everything)融合的网络规划,最后结合具体的应用案例分析MEC在车联网场景中的应用。
Abstract
The large-scale construction of 5G wireless communication network enhances the development of C-V2X (cellular-vehicle to everything) towards diversified directions.Large bandwidth services
such as high-definition video and AR/VR
bring great transmission and processing pressure to the classical network architecture.Meanwhile
traffic safety services characterized by ultra-high reliability and low delay put stringent requirements on network performance.The network architecture of providing services and computing localization through setting user panel down to close to the terminals and MEC (multiple access edge computing) can meet the requirements of data short loop transmission and ultra-low delay in the internet of vehicles scenario.The combination of MEC and V2X was explored in depth
the MEC networking scenario
MEC network architecture and the key technologies and challenges of MEC were analyzed.The combination scheme of MEC and C-V2X integration of network planning was provided.The application of MEC in C-V2X was presented in several specific scenarios.
