VALUE ADDED SERVICES

摘要

In the recent years, computer, Internet and IP technology developed very fast in the world. This provides a strong technical support for the development of VAS. With the pervasion of IP technology in telecommunication networks, the application of soft switch technology and the evolution to 3G, the telecommunication networks will have greater capability for supporting various VAS. With the transfer of telecommunication services from voice service to data service, all kinds of the traditional telecommunication networks carrying the services, such as the access networks, transmission networks, and signaling networks and so on, also change to a single carrier network system based on connectionless IP technology.
