Research For Fixed Networking Softswith Developing Strategy And Technology Of Networking

With the development of telecommunication technology, controlled services open to operators, IP based network progresses rapidly, and requirements of new services expand very quickly. All these phenomena bring great challenge to telecommunication networks. Fixed network operators have to face to cruelty fact. The first fact is that VOIP shares traditional long-distance service. The other is that mobile phone service takes the place of local communication service. The essential method leading to prosperity and keeping ahead for fixed network operators is service innovation. It stimulates the consumption of telecommunication, increases ARPU, creates new services and enhances income of service, which makes telecommunication enterprises capable of developing.This paper analyzes the necessity and feasibility of introducing and developing soft-switching - network based on analyzing its characteristic development and tendency. And expound some important issues, such as principle and cut-in point of soft-switching - network, evolution, service development and supporting system of the network.Establishment strategy of network has been discussed in this paper, including the core network, soft-switching technology, communication to other networks, network for services and network which burden services. This paper focuses on technology which achieves QoS guarantee, core network and accesses network technology of networks which burden services.As a new fixed network operator, Netcom in Fujian province should build and develop soft-switching - network. This paper analyzes the orientation and realization of soft-switching - network based on the real statuses of Fujian Netcom. Fujian Netcom takes soft-switching - network as core service network.. Besides original voice service, special services which are difficult to realize for conventional networks are available now such as video, extra services, multimedia. As the chief technology of network evolution in Fujian Netcom, soft-switching - network should be able to communicate with PSTN network, IN network. And this technology must coordinate with development of network..
