Many books have been written about IMS, so why do we think another is needed? Most of
the existing books are written from the perspective of those who implement the technology,
either network vendors or operators. There is no such focus for developers. The standards
that form the basis of IMS are complex – as they are designed to solve complex problems –
and require specialized knowledge to understand. Developing services and applications on
IMS requires a different set of skills and knowledge, however, and these are generally overlooked
in existing books. This book covers these aspects, from creating small applications to
utilizing the full features of IMS Communication Services and RCS.
This is a unique IMS book, therefore, written not from the perspective of building an
IMS system, but from using it to create new and interesting services. We base this on many
years of practical engineering experience, pointing out the important bits as we go along so
you can avoid getting lost in the detail. This includes a walk-through of the IMS infrastructure,
but in a novel way: starting from fi rst principles, then gradually introducing the core
concepts. We also provide examples of how services are built: general service composition
principles as well as standard services like Multimedia Telephony, and industry standard
service profi les like Rich Communication Suite (RCS).
. Clear, concise and comprehensive view of IMS and Rich Communication Suite (RCS) for developers
. Shows how to use RCS to create innovative applications for rapid uptake by end-users
. Covers service and operator scenarios for the IMS architecture
. Explains IMS architecture and protocols, from an application developer's perspective
IMS Application Developer's Handbook gives a hands-on view of exactly what needs to be done by IMS application developers to develop an application and take it "live" on an operator's network. It offers practical guidance on building innovative applications using the features and capabilities of the IMS network, and shows how the rapidly changing development environment is impacting on the business models employed in the industry and how existing network solutions can be moved towards IMS. Elaborating on how IMS applies basic VoIP principles and techniques to realize a true multi-access, and multimedia network, this book ensures that developers know how to use IMS most effectively for applications.
Written by established experts in the IMS core network and IMS service layer, with roots in ISDN and GSM, with experience from working at Ericsson, who have been active in standardisation and technology development and who have been involved in many customer projects for the implementation of fixed mobile converged IMS network and service. The authors of this book bring their in-depth and extensive knowledge in the organizations involved in the IMS standardization and its architecture.
