Overview

• The notion of IMS enablers and their role for future combinational services

• SOA in Telcos and Internet: Web 2.0 and Mash-up APIs

• Case study: Facebook extensions with IMS enablers

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


5

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)

T. Magedanz (TU Berlin / Fraunhofer FOKUS) - 2007

11

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

• SOA in Telcos and Internet: Web 2.0 and Mash Up APIs


• Summary


21

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
