Paper Abstract

An important feature of the next-generation network (NGN) is that it is predicated on network convergence architecture, providing all types of services, such as telephone and broadband services, on a single network. This is expected not only to reduce the CapEx and OpEx of carriers' networks but also to lead to the creation of a variety of integrated services. The core technology for network convergence is IP-packet-based integrated multimedia technology. The IP Multimedia Subsystem (IMS) plays a central part in this. This presentation describes the role played by the IMS and its related technologies in achieving secure and QoS-guaranteed IP multimedia communication, and integrating a variety of services. In addition, it introduces NTT's NGN field trial, in which this technology is being verified.
