Focusing on the future network architecture and its main principles, Converging NGN Wireline and Mobile 3G Networks with IMSprovides an overall picture of state-of-the-art networks and the role of IMS in these networks. After a full introduction to IMS that spans market trends, commercial drivers, technological innovations, and migration issues, the book discusses the sources of standards and their particular areas of activities. Subsequent chapters center on important aspects of IMS that go beyond session control and multimedia handling to include ID management, service profiles, event triggering, flow- and event-based charging mechanisms, and service-based quality of service. The author also examines network admission, security, border control, and legacy services, enabling a thorough appreciation of new network requirements. Wherever possible, she not only points out convergence of the standards but also covers the different specifications and terminology for TISPAN and 3GPP.Delivering deep insight into the role of IMS in fixed line and mobile networks, this guide fosters a clear understanding of the next generation of converged communication.
