Kurzbeschreibung
The IMS (IP Multimedia Subsystem) is the technology that merges the Internet with the cellular world. It makes Internet technologies such as the web, email, instant messaging, presence, and videoconferencing available nearly everywhere at any time.
The third edition of this bestselling book is fully updated and provides comprehensively expanded content, including new chapters on emergency calls and on Voice Call Continuity (VCC). As well as this, The 3G IP Multimedia Subsystem (IMS) presents updated material including a comprehensive picture of Session Initiation Protocol (SIP) as well as its applicability to IMS. As most of the protocols have been designed in the IETF, this book explains how the IETF developed these protocols and describes how these protocols are used in the IMS architecture.
This is an indispensable guide for engineers, programmers, business managers, marketing representatives and technically aware users who want to understand how the IMS works and explore the business model behind it.
* New chapters on emergency calls, Voice Call Continuity (VCC), service configuration (XCAP, XDM), and conferencing
* Fully updated throughout, including Policy and Charging Control (PCC), QoS, Presence, Instant Messaging, Multimedia Telephony Services, and Push-to-talk over Cellular (PoC)
* Describes the IP Multimedia Subsystem from two different perspectives: from the IETF perspective, and from the 3GPP perspective.
* Provides details on the latest policy technology and security architecture
* Written by experienced professionals in the field.

Format:Gebundene Ausgabe
Dieses Buch gibt einen tiefgreifenden Einblick ins IMS. Dennoch ist der Schreibstil sehr einfach und verständlich gehalten. Viele grundsätzliche Prinzipien werden öfter wiederholt und sorgen so für einige Aha-Effekte. Zudem ist das benutzte Englisch sehr bodenständig und somit auch für Leser zu empfehlen, deren Englischkenntnisse sich auf die Grundlagen der Sprache beschränken.

A mixed bag
22. August 2006
Format:Gebundene Ausgabe
This book intends to be the de facto handbook for IMS, but it ends up being mostly reference material.
While it has some fairly detailed descriptions of the standards and protocols involved, it does not go beyond the specifications already publicly available, or the methods that some vendors already use. Some chapters read like a translation of technical drafts, while others concerning less defined areas are very high level.
The authors, while doing a good job assembling useful information, probably set out to write this book too early, when IMS was still only a reference framework, without widespread service provider adoption. Furthermore, the corresponding expertise across the industry is missing, thus making this a less elaborate view on the services that IMS would provide, compared to what the book's subtitle would suggest.
If you need a book on IMS right now, and are not happy with the abundance of online materials, buy this book. If you are looking for a comprehensive guide on what IMS means for providers and customers, I personally have not read such a book yet - but even if it has not been released, it is only a matter of time. Keep your eyes peeled for snippets of information coming out of service providers and infrastructure vendors, and for the ongoing debates in the industry around the evolution of the service delivery platform.

Great book for those needing to know about IMS
4. Januar 2005
Format:Gebundene Ausgabe
My original review of this book was based on the 1st edition which contains some typos which could make it a bit hard to read.
I am now revising this review to reflect the 2nd addition that is now available. The editors did a much better job on this edition and there is plenty of new content to make it worth the purchase.
This is a great book to acquaint the user with IMS, its history and how it fits into the Internet landscape. The authors have done a good job of covering the entire IMS space.
This is a must have book for anyone needing to get up-to-speed on IMS.
For anyone who will be working with IMS regularly, they will want to also familiarize themselves with the 3GPP specifications ([...]) since IMS is still a developing technology. There are already a number of changes to IMS that are not documented in the 2nd edition since the specifications are still being worked on.
Not only do I highly recommend this book, but we often give this book to our customers when talking to them about IMS.

Great Reference Book
21. Oktober 2004
Format:Gebundene Ausgabe
If there is one book you have to buy for IMS, make it this one. The authors clearly explain the benefits of this new Multimedia domain and then go on to describe the architecture in no-nonsense, easy to understand terms. A basic understanding of 3GPP network architecture and the SIP protocol are required pre-requisites. An Extensive reference section will allow the user to dig deeper in any topic of their choosing. A must have reference book!!
