T1: IMS and MMD as NGN Application Enabling Platforms - Practical Experiences from the FOKUS Open IMS Playground
by Thomas Magedanz
Speakers:
Dr. Thomas Magedanz is full professor in the electrical engineering and computer sciences faculty at the Technical University of Berlin, Germany, leading the chair for next generation networks.In addition, he is director of the “3G beyond” division of the Fraunhofer Institute FOKUS, which also provides a national Next Generation Network testbed in Germany. Since more than 18 years he is working in the convergence field of fixed and mobile telecommunications, the internet and information technologies, which resulted in many industry driven R&D projects centred around Next Generation Service Delivery platforms. In the course of his research activities he published more than 200 technical papers/articles. In addition, Prof Magedanz is senior member of the IEEE, editorial board member of several journals.
Based on his long experience in the teaching complex IT and telecommunication technologies to different customer segments in an easy to digest way, Prof. Magedanz is a globally recognised technology coach. His employments as university professor and division head of a major German R&D organisation make him a prime choice for such trainings, as he is able to provide a non-biased presentation of the technologies. He regularly provides strategic and technology briefings for many tier 1 and 2 operators and major international telecom vendors. As well, he acts often as invited tutorial speaker at major telecom conferences and workshops around the world.

T1 Description:
Next Generation Networks are based on the convergence of fixed and mobile telecommunications, the internet and information technologies. In these NGNs the seamless provision of an open set of multimedia communication and information services is driving the development of new IP based service architectures, such as the 3GPP IP Multimedia (Sub)System (IMS) and the 3GPP2 Multimedia Domain (MMD). This tutorial looks at the IMS/MMD motivation, architectural principles, standards and applications. Special attention will be given to the different IMS application server options, namely CAMEL, OSA/Parlay and SIP Application Servers and the general linkage of the IMS/MMD Core and the IMS/MMD application layer.
An overview of the Open IMS play ground @ Fraunhofer FOKUS (www.fokus.fraunhofer.de/ims) will provide first hand experiences with IMS infrastructure integration from different vendors and FMC applications provision. The tutorial ends with a Questions and Answers session.
The seminar is structured into the following parts
1. IMS Drivers and Principles
- From VoIP to IMS - Internet plus Intelligent Networks = IMS
- Architecture principles of all IP networks - routers, session servers and application servers
- The basic IETF protocols: SIP and Diameter
- IMS/MMD as target NGN SDP
2. IMS/MMD Standards
- IMS Standards overview (3GPP, 3GPP2, ETSI, OMA, etc)
- IMS key components (CSCFs, MG, MS, SIP-AS, HSS)
- IMS key interfaces (ISC, Sh, Cx)
- IMS Registration and Session Control
- IMS Charging & Security
- IMS QoS Issues and relation to underlying access networks
- Differences in 3GPP IMS and 3GPP2 MDD
3. IMS/MMD Service provision principles and interfaces
- General AS operation and interfaces (ISC, Sh, Rf, Ro)
- AS service provisioning in the IMS (filter criteria vs. service identities)
- AS Operation modes and example call flows
- AS orchestration
- IMS Application Server options
4. AS Options: CAMEL, OSA, SIP AS
- CAMEL Basics (IN in the mobile world)
- CAMEL Phase 4 usage within IMS
- OSA/Parlay Basics
- OSA/Parlay usage within IMS (Mapping OSA to IMS)
- SIP AS Definition and Standards
- SIP servlets for converged IMS applications
5. IMS Applications
- Towards Standard IMS Applications - Relationship of 3GPP and OMA
- From Push2Talk / PoC to IMS based Community Services
7. FOKUS Open IMS Playground
- FOKUS Open Source IMS Core and Partner IMS components
- IMS Playground Applications
8. IMS Summary and Open Issues
- Operator IMS Introduction Strategies - review of the market situation
- IMS Open Issues and F&E Topics
- Question and Answers
