摘要: 基于铁路GSM-R系统核心网改造的需求,提出改造方案。针对MSC改造,提出R4网络架构主备MSC方式和R4网络架构MSC Pool方式,并进行方案比选;针对SGSN改造,提出兼容两种BSC/PCU的组网方案,并进行方案比选;针对GGSN改造,提出两种冗余方式。并从站址选择、承载网通道提出了相应需求。最后探讨新旧核心网设备割接的方案。

Abstract: Based on the demand of core network transformation of GSM-R system, this paper proposes core network transformation schemes. For MSC transformation, the master/standby MSC mode of R4 network architecture and MSC pool mode of R4 network architecture are proposed, and the schemes are compared. For SGSN transformation, a network scheme compatible with two BSC/ PCUs is proposed, and the scheme is compared. For GGSN transformation, two redundant modes are proposed. The corresponding requirements for site selection and bearer network channel are put forward. Finally, the cutover scheme of old and new core network equipment is discussed.

Key words: GSM-R core network, redundant networking, MSC, SGSN, GGSN, service cutover
