IMS Bible and IMS Bluffer's Guide

I'm constantly getting asked (particularly by those in commercial/marketing functions within Operators) for the best introduction to 'What IMS is'. Below are our favourites (see also earlier posting on this blog which gives chapter and verse on how to find IMS information).

The first, from The Moriana Group, is "the bible" and the second, on Wikipedia, is the "bluffer's guide":

An Operator Guide to IMS and New Generation Networks and Services.
In August 2005, The Moriana Group released a major report on IMS entitled: An Operator Guide to IMS and New Generation Networks and Services. This report includes surveys on the IMS Core Network, Integrated Services Framework and Charging; application listings, white papers and product profiles from recognized leaders in the IMS space. 20 contributing companies included: Redknee, Microsoft, IBM, BEA, Motorola, Hewlet Packard, Telcordia, Ulticom, Ubiquity, Kabira, jNetx, Appium and others.
The Operator Guide to IMS is available for free download since August 2005 from

Understanding IMS from Wikipedia, the free online encyclopedia

The IP Multimedia Subsystem (IMS) is an open, standardised, operator friendly, Next Generation Networking (NGN) multi-media architecture for mobile and fixed IP services. It's a VoIP implementation based on a 3GPP variant of SIP, and runs over the standard Internet protocol (IP). It's used by telecom operators in NGN networks (which combine voice and data in a single packet switched network), to offer network controlled multimedia services.

Good introductory presentation for audiences who want to understand the basic technology:
