摘要
针对轨道交通行业,对无线数字集群通信系统的部署方式和建设模式进行了研究探讨,阐述不同建设模式下的无线通信系统架构和通信方式的特点。在面对轨道交通行业中无线通信系统建设中存在的基础设施分散、网络资源浪费、系统安全不高等多种问题,提出了容灾互联的设计方案,描述了多种容灾互联部署的应用场景,通过核心网容灾备份,进一步增强了系统的安全性,扩展支持核心网层的互联互通。
Firstly,the deployment mode and the construction mode of wireless digital trunking communication system in rail transit industry are discussed,and the characteristics of wireless communication system architectures and communication modes under different construction modes are also expounded.In the face of various problems existing in the construction of wireless communication system in rail transit industry,such as scattered infrastructures,waste of network resources and low system security,the solution of disaster recovery interconnection is put foward,and various application scenarios of disaster recovery interconnection deployment are described as well.Through disaster recovery backup of core network,the system security is enhanced,contributing to expanding and supporting the interconnection of core network layer.
