The optimization scheme of high-speed railway wireless communication network based on MEC was proposed,in order to achieve the optimization of high-speed railway wireless communication network and meet the needs of safe,reliable and efficient multi-dimensional railway transportation of high-speed railway,based on the analysis of existing high-speed railway vehicle-ground wireless communication network,and combining with MEC which was widely used and popularized in other industries,.Comparing the two models of wireless communication network optimization scheme of high-speed railway,the function of MEC server and MEC platform structure of base station were expounded.Through the application example of high-speed railway,the optimization scheme of wireless communication network based on MEC was systematically described.It provided theoretical basis for the future optimization of wireless communication network of high-speed railway,and provided model support for the research on network delay,wireless transmission optimization,virtualization technology and other aspects.

Key words: MEC, vehicle-to-ground wireless communication, MEC platform architecture, virtualization
