摘　　要：为适应“四网融合”发展趋势,干线铁路、城际铁路、市域铁路、城市轨道交通等的专用移动通信系统之间存在互联互通需求。通过分析城市轨道交通专用移动通信系统业务,对比GSM-R、LTE、5G-R等移动通信技术制式的频率和技术特点,提出城市轨道交通专用移动通信系统互联互通方案。采用LTE网络承载关键业务通信服务(MCX)系统,分别从列车控制业务和调度通信业务两方面,设计采用MCX的LTE与GSM-R、5G-R网络互联互通方案,并给出LTE跨核心网漫游切换以及采用MCX的LTE跨核心网漫游切换测试方案,以提高专用移动通信系统运营的安全性及服务水平,促进多层次轨道交通网络融合发展。In order to adapt to the development trend of“Four Networks Integration”,there are dedicated mobile communication system interoperation requirements among the different rail transit lines including trunk railway,intercity railway,suburban railway and urban rail transit.By analyzing the services of special mobile communication system for urban rail transit,comparing the frequency and technical characteristics of mobile communication technology systems such as GSM-R,LTE and 5G-R,the interconnection scheme of special mobile communication system for urban rail transit is put forward.Using the LTE network to carry MCX system,the interoperation schemes of MCX based on LTE and GSM-R、5G-R are designed from two aspects of train control service and dispatching communication service,and the roaming handover test schemes of LTE across core network and MCX across core network based on LTE are given,so as to improve the security and service level of special mobile communication system operation and promote the intelligent development of urban rail transit.
