Communications Network Based On Ip Softswitch In The Hotel Industry, Application Design And Implementation,

SoftSwitch is a core technology which produces a new generation of voice communication and data alternative. SoftSwitch technology reflects the idea that separates the controlling/business and carrying. As a controlled entity of soft switches, following completion of the call, the user control and business management functions, and the transmission of streaming media business by the IP-based network. Throughout the Softswitch system, the protocol which connected, control signaling has played a central role in the decision to provide operational ability. IETF to develop a new generation of the session control protocol SIP (SessionlnitiationProtocol) ,which has simple, open, flexible, scalable, and many other obvious advantages, become an important technology in next generation network of Softswitch system.At present, the development of soft switch from carrier-class network to the transition of enterprise networks gradually. After several years of development, Cisco as the first verdor provide its Softswitch solution in enterprise-class market, its industry applications have been more mature. Hotel industry as a pioneer in the application of Softswitch has accumulated valuable experience.This thesis expounded the basic concept , major function , network architechture and correlative protocol standard, analysed application of Softswitch technology in communication system of hotel industry. The structure of communication network of hotel industry is more and more complex, through high-star hotel in the detailed design of the solution, show Softswitch technology to the traditional circuit-switched and high availability of the advanced nature. To ensure the continued growth of the hotel information transmission service requirement, the Communication network throughout the hotel management has become increasingly complicated. Introduction of Softswitch technology into hotel communication network can combine resource, manage conveniently, and also can develp new business, to meet hotel communications systems new demands.
