The NGN Networking Scheme Of Dezhou Unicom Fixed-network

The next generation network is a service-driven network, it is the traditional PSTN and IP based packet network fusion products. It adopts a comprehensive, open, network architecture, implementation of complete separation of service and call control, complete separation of call control and bearer,so that the service independent network. It is a packet based network, the network is able to provide telecommunications services and can use a variety of bandwidth, with quality of service provision in the network transmission technology, and business related functions independent of lower associated with transmission technology. The use of NGN, users can randomly access network and can be based on the choice, connected to a competing service providers. It supports the general mobility, this mobility allows users to provide a consistent universal service. At present, there are a lot of NGN networking applications pilot in the country. NGN business network will carry out large-scale deployment from 2011, and NGN research emphasis will be transferred to the new service development and new application by 2013.On the theoretical study of the NGN very much, but in the current network environment, the NGN actual network application is not mature, there may be a variety of problems, especially in the development of new services and applications, to some extent, it affects the development of new services and applications.The paper through the NGN networking research, analysis of the NGN network design mechanism, studies of NGN and its key technology principle, exploration of NGN in commercially available that may arise in various problems, and seek for the existing network environment scheme.The paper through business testing and practical application construction, combined with the existing communication network evolution, it aims to design an accord with Dezhou Unicorn's actual application of NGN networking scheme, the paper unified Dezhou Unicorn's NGN scheme, it explains completely the technique details and possibility in the NGN evolution, and through the NGN network structure and other aspects of the correction and optimization, realizes the maximum saving investment,protecting investment, improve network reliability objective. The research content of this paper is the research hotspot of communication industry, having wide application prospect.
