中国电信最大的优势是固定电话网,而同时最大的包袱也就是固定电话网的改造和演进。以低成本、高起点为主题分析如何对中国电信庞大而陈旧的交换网进行改造;以“网络收敛”的主线思想,探讨了从“交换功能集中”到“用户数据集中”的网络优化模式,提出了实现交换智能化的方案。2003年常州本地网完成了以汇接局为交换核心和功能核心的本地网一级汇接结构,并进一步实现了交换集中化、端局模块化。2004年进而引入了固定电话网HLR,实现了用户数据集中。
China Telecom’s biggest advantage is the fixed telephone network, while the biggest burden is the transformation and evolution of the fixed telephone network. With the theme of low cost and high starting point, it analyzes how to transform the large and outdated switching network of China Telecom; and discusses the network optimization mode from “exchange function concentrated” to “user data concentrated” with the main line of “network convergence” Proposed to achieve the exchange of intelligent programs. In 2003, Changzhou local network completed the local network first-level tandem structure with exchange center and function core as the exchange office, and further realized the exchange centralization and the end office modularization. 2004 further introduced the fixed telephone network HLR, to achieve the user data center.
