It is a very good book on the next generation evolution of Telecom and that is IMS.

This book has almost everything written on the concepts of IMS and it's evolution.

Citing good examples with pictorial diagram and call flows.Which will definitely help a beginner to

an experienced person to understand IMS.Well defined call flows,well defined architecture,well defined IMS interfaces and some of the latest features that can be implemented by following the concept of IMS are well written.



But I think the price of this book is little at a higher side.That is the only thing.



But still if you have a hunger to learn IMS,I think purchasing this book is worthy.



Thanks,
