Abstract
Softswitch is a new calling control technology that has been developed in recent years. It features the open architecture and the packet-based transmission while has the capability to support multiple access modes. It can offer multiple real-time services including voice and multimedia services, and gradually becomes a leading technology for the evolution of the circuit-based network to the packet-based NGN. Although the evolution of the circuit switching to packet-based Softswitch is a technical trend, the circuit-based network and Softswitch network will coexist for a long time.The fact is that the Softswitch technology is close to maturity, and the technologies for building a Softswitch commercial network have been prepared well. It is an important technical development of the telephone network to use the Softswitch technology to support the evolution of circuit switching to packet switching. The Softswitch system is composed of the network equipment and the terminal equipment.The former includes the Softswitch equipment,trunk gateway, signalling gateway, accessgateway, media server and application server.The latter has the Integrated Access Device(IAD), SIP terminal and more.
This article unifies actual situation of X city Network, Elaborating the network intellectualization necessity from market competition, service development, network structure and security, professional ability, maintenance management and so on several aspects. The softswitch technology is core technology of the next generation network, it will be the next network development tendency.
The full text may divide into three majorities: The first part contains the first chapter. It analyzes the main existence problem of X city Network and describes the main content of NGN. Then lead out the background of implementing network intellectualization and then analyzing the necessity and feasibility implementing network intellectualization.
The second part is the second chapter. It analyes the situation of presently network and main existence problem of X city Network and the service type which the local network of X city Network can provide.
The third part is the third and forth chapter.It is the key content of this article.it compares two possible construction projects first, then chooses a viable construction project.Successively elaborated softswitch network design principle, the rules of network resources turns etc.
Key words: Network intelligence;Softswitch technology;NGN
