Seamless Services – The Net doesn’t Matter• Network diversity and network innovation pace has lead to
network abstraction based on IP as common denominator• Connectivity Services versus Multimedia Services• Users are interested in services – thus end systems and Service
Platforms matter
Network Diversity is not a problem anymore due toAll-IP evolution

The Internet has changed the Telco World
• Network technology impacts Circuit switched evolution towards all-IP networks
• Service technology impacts SIP-centered service platforms (IMS), Web 2.0 / SOA
• Business Modeling impacts open services market, Subscription vs. Advertisement payments
• Communication services in the future will be strongly integrated with information services – traditional boundaries will blur
• Strong shift from person to person communications towards group communications Communities
• Combinational services centered around presence information and contexts of live I-centric Communications / human-centric communications
• The result is a Convergence of formerly different domains into one

Where does the money come from in the future?
• Declining revenues for plain voice services• Declining revenues for plain Internet access• Hope is in
– service bundling (FMC, 3P)– value added multimedia services (IMS)– content provision (IPTV)– partnerships (3rd party interfaces, Web 2.0, Google & Co)
• In addition network operators have to save in CAPEX and OPEXinfrastructure evolution towards uniform Next Generation Networks
(NGNs) and service delivery platforms (SDPs)

The Emerging Split of Operator Roles
So far Operators offered network specific services, but in the future they need to focus their business activities as- NetCos = Bitpipe Providers- ServiceCos = Platform Providers / Enablers / Brokers- Sales Cos = Customized Application Providers with direct Market Access

Web-based Telco Enabler Exposure Examples
• British Telecom´s 21c Web SDK based on extended Parlay X Web Services based interfaces (http://web21c.bt.com/)– New possibility of defining user-specific call flows in XML for enabler
orchestration– Authentication, conference call, inbound SMS, messaging, voice call
• Orange Partner API based on Web Services (French market only) and XML-RPC (http://www.orangepartner.com)– Authentication, Personal Calendar, Personal Contacts, Personal
Messages, Personal Photos, Personal Profile– SMS, Email, – Web-based widgets (bubbletop dev platform)

Web-based Telco Enabler Exposure Examples
• T-Online Open Developer Portal based on Web Services and XML-RPC (http://developer.telekom.de) – official start in Q3/4 2008– Voice Call, send SMS
• Sipgate API based on XML-RPC (http://www.sipgate.de/user/download_api.php) – German VoIP ISP– Voice call, send SMS, send Fax– Billing data, call lists

The Home Base - Fraunhofer FOKUS
– FOKUS has been founded 1988 in Berlin, Germany– 220 employees: scientists, students, technicians
originating from 30 nations
– FOKUS is THE Telecoms R&D institute within the Fraunhofer Society
• Fraunhofer Society is the biggest German R&D organisation, total # of 12.000 employees)
• 60 institutes in total, 15 institutes in ICT
– FOKUS works since 18 years on convergence of IT, telecoms, internet and home entertainment and performs applied research and development projects
• Performs strategic studies, solution concepts, system integration and prototyp developments
• Strong cooperation with universities & Establishment of spin offs (e.g. iptelorg.com)
– FOKUS fundung: 20% state, 80% industry R&D projects
• Key to success: Strategic Partnerships with big players (DTAG, NTT, Telkom SA, O2, etc)
– Main R&D Vision: „I-centric communications“ and „autonomic communications“

Open NGN Test & Development Center– Testbeds are considered key for
sustainable research– Testbed focus is on IP and service
platform layers– Foundation for industrial and academic
projects• Applications development support• Applications validation• Service Platform prototyping• Infrastructure component testing• Network technologies integration

Summary
• Network convergence will lead to an increased importance of services• The NGN is the last chance for telcos to position themselves right
within the emerging multimedia services world• Telcos need to set up partnerships to stimulate reuse of „telco
enablers“ within an emerging web-based converged services world• The FOKUS Open SOA telco playground addresses the challenges of
IMS service creation, provision and management in face of emerging SOA and Web 2.0 services
• Web 2.0 killer applications, such as Facebook, can be easily extended by IMS enablers, if the enablers are exposed in the right way
