Abstract

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.

Key words: 5G, MEC, C-V2X, hierarchical deployment
