The Fixed-Line Intelligence Technology Implementation Research Of Yunnan Telecom

Nowadays the competition in the telecommunication market is so intense that diversity and individuality has become the main focus for major operators to gain bigger market share. Therefore, it is becoming increasingly important and urgent for traditional fixed-line operators to upgrade their voice network into an intelligent network so they can provide the market with open, flexible, and quick response services.This paper is based on the background information of the implementation of the fixed-line intelligence reconstruction program of Yunnan Telecom. The necessity and feasibility to fully implement the fixed-line intelligence over the entire network has been proved. The paper studies and analyzes the needs of the reconstruction work, the services provided by the intelligent network, as well as three kinds of interactive protocols used between SHLR and fixed-line equipment unit. The results include the business needs and implementation proposal of fixed-line intelligence program, also have detailed description of the network architecture, the realization of key infrastructure SHLR and the business implementation process.This paper has mainly accomplished following aspects :1．describes the background and business needs analysis of the fixed-line intelligence reconstruction project2．capacity and reconstruction need analysis of existing networks (including the exchange network, intelligent network, signaling network, IT support network)3．SHLR realization analysis based on collected subscriber data mode4．studies the interactive process between SHLR and fixed-line equipment unit through ISUP+,MAP, MAP+ protocols, and how to provide inquiry function for both calling parties with basic and value-added business information.5．compares three implementation schemes using different protocols of ISUP+, MAP, MAP+ .6．puts forward the fixed-line intelligence implementation proposal for Yunnan Telecom.With the implementation of fixed-line intelligence, NGN soft-switch and other projects, a solid base will be founded for the fixed-line operator to realize its strategic transformation and to absorb new vigor and vitality into the traditional network .
