摘要
MSC池(MSC in Pool)是由3GPP规范定义的,能优化整个移动网络的组网。本文简要介绍了MSC Pool技术的基本原理及其组网特点,分析了MSC Pool所用到的关键技术(NRI路由机制和负荷分担),重点讨论了核心网D接口信令的流量,根据MSC Pool的技术特点,提出了组网规划的前提条件和规划时需要注意的问题,最后总结了MSC Pool技术的特点,在结论部分给出了MSC Pool可能存在的安全隐患。
Specified in 3GPP, MSC pool （MSC in Pool） is to optimize the Structure of the entire mobile network. This paper introduces the basic principles of the MSC Pool technology and the network characteristics, analyzed the key technologies of MSC Pool （NRI routing mechanism and load-sharing）, focused on the signaling traffic of the core network interface D, according to the technical characteristics of MSC Pool, put forward the prerequisite of the network planning and the problem which needs to pay attention to, concluded the technology advantages of MSC Pool, in the conclusion pointed out the security risks of the MSC Pool.
