Tutorial 4

The 3GPP/3GPP2 Multimedia System (IMS) as NGN Service Delivery Platform: Principles, Standards, Architecture and Applications


Time: Monday 27 June 2005

Instructor: Thomas Magedanz, TU Berlin / Fraunhofer FOKUS, Germany


This tutorial provides a technical overview of the architecture, components and protocols of the emerging 3GPP IP Multimedia Subsystem (IMS) / 3 GPP2 Multimedia Domain (MMD) which provides the technological basis for the provision of mobile multimedia services within converging networks. This tutorial looks at the driving forces for the IMS architecture definition, introduces the key signalling and control protocols of all IP networks (i.e., SIP and Diameter) forming the basis for IMS component interactions, and explains the key IMS elements and their interactions. Special attention will be given to the IMS application server options, namely CAMEL, OSA/Parlay and SIP AS. The tutorial will also address current IMS products, deployment status and open issues tackled in Release 7. The tutorial ends with an overview of the FOKUS IMS play ground (

The seminar is structured into the following parts

1. IMS Drivers and Overview

2. IMS Basics: SIP and Diameter

3. IMS Standards

4. IMS Application Server options

5. IMS Summary and Open Issues
