IP Multimedia Subsystem will provide the reader with an understanding of IMS technology and the possibilities of IMS services and applications. The first three chapters of the book are an introduction to IMS and its core components before moving on to the deployment of IMS. This includes sections on IMS applications and services and the impact of IMS on application developers. The book will also provide performance measurements on a live IMS test bed connected to an operator network and present substantial material on post-IMS possibilities and issues relating to integration with the web services and its co-existence with the emerging Web 2.0 technologies.This is one of the first books to cover IMS services and applications from a deployment perspective. The industry does not currently have a comprehensive study of deployment issues for its reference. The content related to IMS test networks design and implementation will be of great value and relevance to the operators working towards IMS deployment. With the emergence of Web 2.0 technologies in the internet domain, IMS advocates are forced to look beyond IMS deployment and towards integrating IMS with Web services. The book aims to enable a better understanding of how web technologies can complement the IMS service architecture and pioneer the post-IMS progress and success. One of the first books to cover IMS services and applications from a deployment perspective Includes performance measurements on live IMS test bed connected to an operator network Looks at how web technologies can complement the IMS service architecture Examines the current status of Mobile WiMAX deployment from the perspective of operators, service providers, vendors and developers.
