摘要
基于对重载铁路机车同步操控业务的分析,首先提出5G-R承载机车同步操控业务的网络架构,以及核心网、无线接入网等冗余组网方式。其次从数据路由、会话和服务连续模式、IP地址分配等方面,研究机车同步操控业务在5G-R网络中的实现方式;其中数据路由可采用归属地路由方式,会话和服务连续模式建议采用SSC模式1,对于不同核心网架构给出3种IP地址分配实现方案。最后对既有重载铁路建设5G-R网络进行方案探讨,包括以大秦铁路为例,提出5G-R网络建设方案,以及机车同步操控系统地面设备和车载设备的改造方案;以朔黄线为例,提出与既有业务运用相适应的5G-R网络双网冗余组网且业务负荷分担方案。通过对5G-R系统承载重载铁路机车同步操控业务的网络架构、工程应用等研究和分析,为未来5G-R系统应用于重载铁路提供一些参考。
Based on the analysis of locomotive synchronous control service for heavy haul railway,the network architecture of 5G-R bearing locomotive synchronous control service and redundant networking modes such as core network and wireless access network are proposed.On this basis,the implementation mode of locomotive synchronous control service by 5G-R network is studied from the aspects of data routing,session and service continuity mode and IP address allocation.Data routing adopts the home routing mode.SSC mode 1 is recommended for session and service continuity mode.Three IP address allocation schemes are given to correspond to different core network architectures.Finally,the scheme of 5G-R network construction of existing heavy haul railway is discussed.Taking Datong-Qinhuangdao Railway as an example,the scheme of 5G-R network construction and the renovation scheme of ground equipment and on-board equipment of locomotive synchronous control system are proposed.Taking Shuozhou-Huanghua Railway as an example,a dual network redundant networking and business load sharing scheme for 5G-R networks that is suitable for existing business applications is proposed.Through the research and analysis of the network architecture and engineering application of 5G-R system bearing locomotive synchronous control service in heavy haul railway,some references are provided for the future application of 5G-R system in heavy haul railway.
