摘　　要：随着中国GSM-R网络规模的扩大和核心网的逐步建成,MSC、BSS容灾和网络安全越来越重要。分析GSM-R MSC及BSS的设备及连接故障所产生的影响,提出容灾备份措施,研究"双归属"和"MSC pool"等方式MSC冗余备份方案,讨论基于电路割接、无线覆盖冗余等方式的MSC及BSS备份,可供GSM-R网络冗余设计和实施参考。With the expansion of Chinese GSM-R networks and the gradual setup of their core networks,disaster recovery and network security of Mobile-service Switching Centers and Base Station Subsystem become important.We analyzed the impact of GSM-R MSC and BSS equipment failures and their connection interruption and proposed disaster recovery measures,which mainly focus on MSC redundant backup solutions,double belonging and MSC pool,and discuss circuit cutover and wireless coverage redundancy based backup measures for MSC and BSS,offering references for redundancy design and implementation of GSM-R network.
