Research And Implementation Of Optimization Project For Native PSTN In Xinzheng City Of Henan Province

From now until 2010, it is a critical period for China to achieve not only great strategic objective, but also modernization of information and communication. There are multiple important things for China should be done during this period. And the following is typical ones. Firstly, China should establish a relatively complete socialist market economic system and maintain a sustained, rapid and healthy development; Secondly, China should promote an information-based economy, have the support of information and communication industry and promote the revitalization of the adjustment and optimization of the economic structure, promote the formation of the market mechanism and the development of regional economic meanwhile, China has begun to take shape in the face of information and communication technology upgrade and further expand perfect .Therefore, it is very important to transfer from narrowband to broadband, a single Internet network to integrated network, automatic network to the Intelligent network..With the operation mode of Xinzheng City branch of this company gradually shift center call from network equipment to the business and service. Particularly, this change in order to meet the demand for all local Call business concentrate to all the Regulation of the Internet, achieve centralized management of users operational attributes, develop value-added services, gradually transform the local network to implement intelligent network. Therefore, there is a higher demand for the exchange network and equipment integration of management and integration of business supports. Taking into account Xinzheng branch company 04 exchange system had expanded equipment repeatedly, especially, early building switching equipment has operated on line for more than a decade, switching equipment has serious aging, System capacity is limited, it is necessary to transform the current NGL04DE exchanged optimize system.In this paper, firstly the research background and research content are introduced, and then NGL04 platform technologies, including multi-service integrated platform NGL04 characteristics, system structure and control modes are presented. Following analyze NGL04 network optimization technology, including the appliance scope of fixed network optimization, the three kinds of modules of network optimization and the capability which NGL04 network optimization changes. Then analyze the fixed network existing problems, confirm the network optimization implement project based on the network optimization principles and objectives and particularly introduce the process of implementation the program implementation. Final evaluate the results of the implementation, through the implementation the network structure is simplified, the efficiency of network operators is improved, the system capacity is upgraded and the stability of the exchange system advanced. There is a reference value for the demand of network optimization to a certain city branch, and provide a certain reference for transformation of the majority of fixed network switches.
