Abstract: Combined with the existing railway communication system architecture, the development trend of the next generation railway communication network is expounded. This paper puts forward the intelligent vision of railway communication network, points out that the railway communication network will evolve to the direction of ubiquitous interconnection, cloud network collaboration and DOICT technology deep integration. This paper analyzes the emerging technologies and technical systems represented by cloud computing, software defined network (SDN) and artificial intelligence (AI), and puts forward suggestions on ICT technology architecture suitable for railway communication network, which is of guiding significance for the evolution direction and overall architecture of the next generation railway communication system.
