摘　　要：随着通信技术的不断发展,基于IP的Gb数据传输(简称Gb over IP)成为GSM-R网络的研究焦点。重点围绕GSM-R系统中BSC/PCU设备以Gb over IP方式接入核心网的方案开展研究,针对BSC/PCU与核心网设备异地设置时,BSC侧无法感知跨传输系统后链路中断,导致保护倒换机制未触发引起业务中断的问题,提出3种解决方案,并进行方案比选与优化,为GSM-R系统BSC/PCU设备以Gb over IP方式对接核心网方案提供操作指导及优化建议,以满足铁路移动通信系统多场景下的组网需求。With the continuous advancement of communication technology,Gb data transmission based on IP(“Gb over IP”)has become a focal point of research in GSM-R networks.This study focuses on solutions for the connection of BSC/PCU equipment in the GSM-R system with the core network via Gb over IP.When BSC/PCU and core network equipment are deployed in different locations,the BSC may fail to detect link interruptions.This results in the protective switching mechanism not being triggered,leading to service disruptions.Therefore,the paper proposes three solutions.Based on a comparison and optimization of the solutions,the paper provides operational guidance and optimization recommendations for the connection of BSC/PCU equipment in the GSM-R system with the core network through Gb over IP,aiming to fulfill the networking requirements of railway mobile communication systems across various scenarios.
