Design And Engineering Practice Of Huaihua Tietong Next Generation Network

The Huaihua railway company’s communications network consists of fixed voice network and data network, two mature and stable network structure, its income is distributed mainly in fixed telephone and Internet users, but because the two networks are independent business development, to provide the service is simple, operation mechanism is also different, with the market the increasingly fierce competition, and in the state under the influence of the policy, the telecommunications industry has entered the era of the whole business, the major operators in order to reduce the operation cost, open up new business, increase profit, network integration of the whole business is imminent, and Huaihua railway after so many years of development, the network is gradually protruding comes out now. With the GPON broadband access technologies are introduced, marking the" copper retreat into the light" era, in order to enhance the market competitiveness to meet the future needs of the development of the market, the Huaihua Tietong network reconstruction and optimization be imperative.First the paper provides an overview of the current telecom industry status and market trends, the CRC branch in Huaihua facing the competitive situation and development trend of network, made clear the main task, and the engineering program needs the technology are introduced, including the NGN technology, soft switch technology, GPON technology. according to the Huaihua Railway Branch of the present situation and the existence question, according to the actual characteristics of the whole network, to market demand analysis, grasp the design principle according to the design target to develop the network transformation design. This design scheme is proposed for the first initial network construction scheme:the voice network end office and the transformation in the access network how to utilize GPON technology to access, this stage is the key technology to soft exchange in end office location, the initial soft switching can be positioned as PSTN supplementation and optimization, and the PSTN coordinated development. In the end office transformation scheme, and then put forward the core network construction plan, scheme P2P peer to peer network concept, in stages, the original PSTN speech call of user control and intelligent service triggering in tandem office unified implementation, at the same time, narrowband speech user multimedia terminal user as the soft exchange user can pass softswitch platform of unified call control and intelligent service triggering; SS access to the SHLR can be directly realized through MAP, the phase can be as the Huaihua Tietong future network architecture development goals. In this paper at the same time, the network evolution direction, in the PSTN network to NGN network evolution process, in the PSTN network tandem office uses the soft exchange network to replace the advantage. Finally in the network security management has also put forward their suggestions. After the implementation of engineering, operational problems were related to treatment.The scheme is implemented, can be fixed telephone network and data network (PSTN IP) preliminary together, improve the network quality, increase business point of growth, for the users to provide voice, data, video, multimedia business as one of the three goals, as Huaihua railway network is further to the peer to peer network evolution and lay a solid foundation and gradually realize the whole network IP, realize the whole business operation.
