移动通信七号信令网网络优化方案研究

Optimization research of No.7 signaling network in mobile communication system

移动通信七号信令网通过结构改造,由原来二级结构调整为三级结构,但随着网络结构的复杂化,接入信令网网元类型的多样化等原因,在改造后存在很多问题。本文主要介绍了七号信令网在三级信令架构下信令路由的安全性、规范性设置原则,重要信令链路存在的安全隐患及优化解决经验,对三级架构七号信令架构的网络优化具有参考价值。

The No.7 signaling network in mobile communication system transformed from secondary structure to the tertiary structure with the structure adjustment. There are more and more problems exposed because of complex structure and diversified access signaling network. It firstly introduces the route safety and normative principles of No.7 signaling network with tertiary structure. And then it proposes optimization solutions against the security risks in important signaling link. It gives a reference value for optimization of tertiary structure No.7 signaling network.
