Research of Railway 5G-R Comprehensive Data Transmission Platform and Security Strategy
5G-R is the main type of next-generation mobile communication system for railways,offering highly reliable broadband data transmission services for intelligent railway operations.To meet the bearer requirements of the 5G-R network,a comprehensive data transmission platform is proposed.This platform enables unified access for various data service systems and applies Software Defined Network(SDN)technology for dynamic routing selection and efficient data forwarding.Based on shared key lightweight access authentication technology,two-way identity authentication is performed for mobile terminals and network-side devices,ensuring the legitimacy verification of heterogeneous terminals within the application domain.
