Abstracts of the 3rd International FOKUS IMS Workshop 2007 Presentations

Tutorial 1:

“IMS Basics, Standards Update and Future Challenges in Face of Web2.0″

Prof. Dr. T. Magedanz, N. Blum – TU Berlin / Fraunhofer FOKUS, Germany

Telecommunications is at crossroads. The ongoing network convergence and the associated idea of providing seamless multimedia information and communication services demands for a structured and globally standardized all-IP service provisioning architecture. This is today represented by the IP Multimedia Subsystem (IMS), which is standardized by 3GPP, 3GPP2, ETSI TISPAN, and CableLabs. Although all these standards are closely aligned, there small differences due to the different targeted access networks (i.e. mobile, fixed, cable, etc.). However, one of the main questions to day is what are the IMS killer applications justifying the deployment of IMS infrastructures and how do IMS-based multimedia services distinguish from the new generation of Web2.0 services. Closely linked to this question is also the question about how IMS as a platform architecture link into Service Delivery Platforms (SDPs) and the corresponding notion of Service Oriented Architectures (SOA). In this tutorial we want to introduce IMS and discuss the above mentioned issues to provide the necessary base for the subsequent workshops and conference sessions. We will also introduce briefly the Open IMS Playground, as well as the related new Open SOA Telco Playground and the Media Interoperability Lab. Thus newcomers to the subject will obtain a sound introduction and experts can gain an update about the key IMS deployment issues.

Workshop 1:

“IMS and Web2.0/SOA”

Led by N. Blum, T. Magedanz – Fraunhofer FOKUS, Germany and A. Jaokar, Futuretext, UK

Today Service Oriented Architectures (SOA) are considered as the state-of-the-art for service delivery platforms. Nevertheless, Service Oriented Architectures have been present in the last years in telecommunications but gaining currently a new momentum. IMS enabler platforms are developed that need new mechanisms in regard of service design, creation, deployment, provisioning and management of seamless services across different access networks and supporting various business models. Furthermore, the WWW has developed new APIs and functionalities that are currently referred to as Web2.0 and service mashups.

This workshop will address current topics in regard of the integration of telco services into Web2.0 mashups and vice versa using Service Oriented Architectures.

Workshop 2:

“IMS and IPTV: A way forward to standardized IPTV environments”

Led by S. Arbanowski – Fraunhofer FOKUS, Germany

In the last couple of years, first triple play offerings have gained considerable attention worldwide. Together with increasing penetration of Voice over IP and other disruptive technologies such as P2P or community based applications, driven by Web2.0 concepts, they foster the convergence between Internet, media industry, and (mobile) telecommunications.

In this workshop experts will discuss how to overcome the restrictions of existing triple play infrastructures and what role IMS can play for future media ecosystems. As possible answer to all those questions, FOKUS’ Media Interoperability Lab will be introduced during the workshop. It’s a feature rich IPTV environment empowered by the well known FOKUS Open IMS Playground.

Workshop 4:

“IMS Testing: Conformance, Interoperability and Performance”

Led by I. Schieferdecker – Fraunhofer FOKUS, Germany

It is essential to explore the possibilities of IMS to implement mobile, fixed, Internet and IPTV converged multivendor environments and upcoming Quad-Play services. Most of the operators are currently experimenting in laboratories with IMS and evaluating possibilities for new services. There is clear need for close to reality IMS environments for validation of operator expectations, preparing demonstrations or trials for specific services based on IMS to show advantages of IMS to management and customers. IMS coformance, intra- and inter-domain IMS interoperability and IMS performance and scalability are important topics that need to be addressed. This workshop will discuss selected aspects on how different test approaches can help evaluate the status and potentials of IMS infrastructures and servces.

With IMS next generation converged telecommunications core network become modular, allowing operators to combine solutions and infrastructure components from difference vendors in a plug-and-play manner, minimizing integration efforts and deployment costs. This is the theory. In order to arrive with the above vision in the real world, intensive interoperability and conformance testing needs to take place. Industry forums such as the Multi Service Forum (MSF) and the IMS Forum have invited for plug-fests and interoperability event to systematically tackle these challenges. This presentation discusses strategies, tools, challenges and lessons learned from IMS conformance testing projects around the world.

o Validation and test of interoperability is key for the success of IMS

o The complexity of the tests requires standardized, automated test procedures

o Learnings from IMS test campaigns around the world show that the road from SIP to IMS is longer and more difficult that many vendors anticipated

Conference – Session 1

IMS Market and Challenges

S. Krems – Detecon GmbH, Germany

Since years the telco sector faces revenue declines on its traditional services. With the introduction of all IP networks and the fragmentation of the value chain this development is even boosted. The Holy Grail to overcome the dilemma has not yet been found. NGN’s are implemented to reduce cost and gain service independence. Service delivery has to follow that paradigm. Moving a Telco towards an all IP based provider is not an item by item task. It has to be understood as a holistic approach changing nearly everything in the organization and operation. Since IMS was announced in the market as open and powerful tool to simplify service creation and delivery it went through the typical hype cycle. The presentation will give an overview of the market situation of IMS today and its realistic perspectives and challenges. An approach is introduced to support the exploitation of the full potential of an all IP migration and the optimal way to an open IP based service control plane.

Roles of NGN applications for potential IMS deployments

E. Mikoczy – T-Com, Slovak Telekom A.S. Slovakia

Short abstract:

- NGN application aspects driving IMS deployments

- Application migration to IMS and related issues

- Service interoperability and standards compatibility

- Converged services based on IMS

- ST experience with IMS testbed

Extended abstract:

Several factors have a direct impact to the operator’s plans for future IMS deployments and feasible NGN migration scenarios. We would like to focus in our presentation on NGN application aspects and their role as drivers for future IMS deployments but also provide overview about related issues and open questions. Operator need to take into account several aspects in case of decision to deploy IMS as unified service control platform for NGN applications (migration of existing applications, user and service profile concepts, introduction of new converged services, interoperability and standards compatibility of early stage IMS platforms etc.). We would like present also ST experience with IMS testbed and some demo concepts.

IMS for NGN – Triple Play and FMC

T. Murakami – NTT, Japan

The NGN to be built by a telecommunications carrier is a converged network that will provide a wide variety of services. The capabilities that are common to and characterize the IMS, and are expected to play a central role in the construction of the NGN are its ability to:

1. simulate the PSTN,

2. provide FMC functions,

3. provide broadband services, and

4. support a variety of applications.

This presentation will introduce NTT’s concept of and plans for the construction of the NGN, and describe how the IMS will be used to achieve the objectives for the NGN set by NTT

Service Brokering: Opportunities and Challenges

N. Huslak – AT&T, USA

A key to providing relevant, compelling, functional, and seamless end-user experiences is the ability to deliver seamless combinations of IMS and web services. This involves managing feature interactions among combinations of currently independent services, orchestrating web and IMS/SIP applications to build complex services from constituent parts, and providing the ability to define, provision, and support customer offers involving such converged applications. A general term for all of these functions is service brokering. In this presentation, we will walk through various types of service brokering, discuss the shortcomings of the Service Capability Interaction Management (SCIM) concept as currently defined and being worked in 3GPP, address some fundamental requirements for a cross domain Service Broker which spans IMS and web services, and outline essential steps in making the cross domain Service Broker concept a reality.

The role of NGN Testbed Federations

T. Gavras – EURESCOM, Germany

Next Generation Networks (NGN) are inherently heterogeneous and the NGN stakeholders have developed and elaborated on a suitable control framework for enabling services across this heterogeneity. NGN testbeds are providing today the mechanisms, through which we are able to integrate and test new technologies, systems and services, as they become available, in existing infrastructures. NGN testbeds mirror the future landscape of deployed infrastructures and have to provide forward looking solutions for:

* enabling testing scenarios across administrative domains

* describing available testing resources

* locating testing resources

* supporting the separation of the provisioning platform from the underlying infrastructure as a means to accommodate clean slate approaches

* further developing the control framework, also to accommodate clean slate approaches

* provisioning of testing services in a network agnostic manner

Next Generation IPTV – A view from the BBC

S. Broad – BBC Strategy Group, UK

There is a view that using IPTV to deliver traditional linear TV is about as sensible as reading written letters down the telephone. We now need to develop new content and services for emerging platforms, or they will not flourish. What does device convergence mean? And what are the new content forms? What role UGC? And which platforms do I prioritise? A contribution to the debate from the BBC.

Towards Next-Generation Media Ecosystems

Dr. J. Novak – University of Zurich, Institute for Informatics/European Institute for Participatory Media, Berlin

Instead of passive consumers of pre-produced, centrally packaged and distributed content, large audience segments have become active co-creators, aggregators and mediators of digital content – their production, exchange and social interaction creates new forms of digital lifestyle and shared social experiences. At the same time the convergence of different media channels (triple play), protocols and services (e.g. IMS, SIP, SOA) in integrated next-generation media networks is creating infrastructures that allow ubiquitous access to digital media across heterogeneous networks, services and end-user devices.

The intersection of these two trends points to the emergence of new kinds of media ecosystems with new roles, actors and technologies, and dynamic configurations of relationships between them. Developing successful next-generation media applications and services requires us to understand how to leverage social (user-centric), economical (e.g. mass market vs. long tail niche audiences) and technological enablers (e.g. IMS vs. P2P).

This presentation examines the critical challenges and opportunities on the road to understanding the main drivers, critical success factors and the role of IMS for building next generation media ecosystems. This includes: 1) strategies and models for integrating and leveraging bottom-up user-generated and top-down professionally managed content production and delivery, 2) enabling tools and technologies for user-driven content aggregation and personalization and 3) user and application level requirements on services integrating different media channels (e.g. IPTV/Voice/IM/Mobile) into new kinds of highly interactive, personalized and shared user experiences.

C-Mobile – Multicast and IMS

T. Mota – Portugal Telecom Inovação, Portugal

Mobile communications are gradually evolving from the basic model of offering point-to-point voice centric services into more complex service provision platforms. Mobile operators have rolled-out their networks: service and content differentiation is now their major driver to attract new customers. Content portals offering multimedia services are one part of this strategy, bringing multimedia streaming content to the mobile costumer. An analysis of recently launched mobile business offers unveils a trend towards services based on the channel delivery model: content is aggregated into a few channels and pushed to many subscribed users. Examples are content-to-person MMS goal notification (one club = one channel) and mobile TV.

The strategic objective of C-MOBILE is to foster the evolution of the mobile broadcast business by providing enhancements to the 3GPP MBMS for systems beyond 3G. It addresses both resource efficiency and service flexibility, by close coupling of broadcast and communication capabilities on all layers, covering the radio access, core network and the service enablers, providing IMS-MBMS convergence and a smooth migration for MBMS evolution, which will be in line with the vision of a federated global multicast broadcast transport as well as emerging beyond 3G standards.

More specifically, part of C-Mobile’s research focuses on how a service oriented core-network can control and manage different types of sessions being provided as part of a service; issues related to session control such as multicast/unicast switching at the core-network level, broadcast system selection and media processing control for multimedia sessions must be provided as part of a MBMS service.

* What can be reused from IMS?

* What level of integration with IMS should be targeted?

* How to ensure inter-working with IMS?

In a second part of talk, we will share some views on possible evolutions of IMS in the context of Telco/Web convergence.


R. Schwaiger – T-Labs, Germany

In MAMS the development and provision of services are integrated so that an SME can develop and operate custom services without any operating resources of their own. MAMS is based on standardized ICT systems (e.g. IP multimedia subsystems) so compatibility with a variety of differing telecommunications providers’ solutions is high.

The core innovation with MAMS is the provision of a graphic user interface and associated development tools. These permit even non-experts in information and communications technology to develop communications and multimedia services and to operate them for their customers. MAMS enables a whole range of ICT service components (e.g. open source developments) to be made available, thus avoiding high license fees for the production environment.

MAMS is being developed within a research project by several partners: Deutsche Telekom, Infineon, Alcatel-Lucent, the institutes FIRST, FOKUS, SIT from the Fraunhofer Gesellschaft and the Technical University in Berlin. This project is also supported by the German Federal Ministry for Education and Research.

Leveraging IMS for a Web 2.0 Economy

S. Holtel – Vodafone Group R&D, Germany

Mashups are one key factor driving innovation within Web 2.0. But to open IMS for mashups will challenge the hithero mind-set of mobile operators. IMS could play a central role in encouraging new business opportunities. They have to accept and play according to the rules driving the future Internet economy.
