摘要
基于城市轨道交通无线通信网络建设情况,分析了目前国内专用无线通信技术在发展中存在的问题,总结了城市轨道交通无线通信网络业务需求。基于无线通信系统的融合,探讨了城市轨道交通无线通信网络的融合建设方式,提出了宽窄带融合、专网公网融合、5G网络融合等方案,并详细阐述了各方案的优缺点。建议应从实际情况进行综合考虑,选择适合的融合方案。
With the background of urban rail transit wireless communication network construction,the problems in current development of domestic special wireless communication technology are analyzed,and the business demand of urban rail transit wireless communication network is summarized.Based on integration of wireless communication system,integrated implementation solutions of urban rail transit wireless communication network are discussed,proposing schemes such as broadband/narrowband convergence,private/public network convergence and 5G network convergence,and the merits and defects of each scheme are expounded.It is suggested to comprehensively evaluate based on actual conditions and to choose an appropriate convergence scheme.
