Abstract: Through customized development of 5G communication equipment for the 5G railway private network, a 5G radio network system for railway stations that includes various devices and transmits communication data according to priority level is established. After network performance testing and optimization, the capabilities of the 5G core network are enhanced, the data traffic in the railway station is diverted, and the coverage of different regional networks and the bearing of various communication services are supported. Additionally, the transmission path based on service priority and other factors is determined, and the intelligent level of railway communication is improved. The proposed system expands the capacity of the communication system, and meets the data transmission needs of intelligent railways.

Key words: 5G public network, radio communication, radio coverage, 5G railway private network
