Customer Reviews

A well written, easy to read reference on IMS

A good and thorough intoduction to IMS and SIP. Easy to read and written in a manner that the book can be re-read over and over again. Has detailed examples on SIP Call flows with sufficient explanations. The book also acts as a bridge for some of us who are unfamiliar with mobile/cellular networks. Hopefully the book will be updated with each revision of IMS. Congratulations to the author.

A must have if you start with IMS

Possibly the best technical book I've ever read. I work with IMS technology and we use the book in our department to introduce IMS to newcomers. But I also work in European projects on IMS and the book is the main reference for most of the other teams involved. You just need this book and the 3GPP specifications for anything you want to do with IMS.

Very Good Book

This is a very good book on SIP-based Internet Multimedia Subsystem. The book nicely depicts both the Internet and the IMS architecture implementation of SIP, AAA, VoIP centric security and policy, QoS, presence service, media encoding and transport, and instant messaging. By reviewing this book, a reader will acquire comprehensive knowledge of emerging VoIP and Video Telephony Layer 5 architecture in wireless network. The book can be used as a senior or master-level text book, a useful review guide for the provider engineers, architects, technology strategist, product managers, and technical managers. SIP programmers, implementers, and standard engineers may find the book "not detailed enough". Since technology described in this book and their standards are rapidly changing, authors need to keep the book regularly updated. Sohel Khan, Principal Technology Strategist, Sprint-Nextel

Great book for those needing to know about IMS

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

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!!
