3. Introduction Source: Probe Group LLC • “Converged voice and data services are the key to revenue growth” • Yankee Group, October 2003 • Service Providers grappling with cost of today’s multiple parallel networks • voice, data, wireless, private ... • Universal agreement that voice packetization will help to achieve convergence • cost efficiency, • service innovation The Need for Top Line Growth Via New Services is the Key Convergence Driver IMTC Forum – May 2005 – Eibsee, Germany

5. IP Multimedia Core SIP SIP IMSPerson to Person IP Connection IP Multimedia Core finds the other terminal and connects the terminals with IP Circuit-switched network (2G or 3G) Find and connect Packet-switched network (GPRS or 3G) Any IP connection (e.g. GPRS, EDGE, WCDMA, WLAN) IP-based services possible between terminals!

6. What new Services does IMS offer? • Person to Person Multimedia Services • Exchange of any file type - data, video, voice • New Services • Rich Voice services e.g. See What I See • Push-to-Talk & Push-to-See • Media / application sharing • Fully Integrated Messaging Services • Person-to-person gaming • …and any of these with group connectivity & presence information • and unlimited number of Services we have not considered yet • Service Integration • IMS allows all voice & data services to be integrated into a single proposition – allowing a variety of user experiences IMTC Forum – May 2005 – Eibsee, Germany

7. Strategic Drivers for IMS • Enables better Value Chain positioning • Provides management of the Service Plane, making the network Service aware • Operators can become a full value added Service Provider • Key Enabler for the IP Commercial models • Introduces Calling party pays (CPP) into IP based Services • Enriches the On-Net user experience • Service charging by event / media types along with managed QoS • Enabler for service-aware IP Interconnect between operators (GSMA) • Only solution today for inter-operator P2P and Rich Call exchange, with event / media types based charging • Allows interworking with ISPs for mobilising existing services based on standardised protocol (SIP) • Potential Enabler for future IP based messaging • Delivers standardised SIP-based Messaging Services • Enables paid interoperability with other players (fixed and mobile) • Improves User Experience based on fully integrated Messaging Services IMTC Forum – May 2005 – Eibsee, Germany

8. P2P Communication €24.8 bn Western Europe Forecast Mobile Service Revenues 2003 - 07 IMS includes major capabilities to support innovative Applications IMS is very well positioned to enhance P2P Communication services ! Info-Entertainment €11.2 b M-commerce €0.8 b Enterprise €3.2 b (Source: The Yankee Group, 2002) IMS supported Capability Partially IMS supported Capability IMTC Forum – May 2005 – Eibsee, Germany

9. IMS Market Drivers • P2P Communication covers the major part of Service Revenues • IMS enables IP based P2P Communications! • IMS can be the key enabler for future mobile internet Services With: • Richer Communication – IMS supports new Rich Call type Services • Reliable – Standardised; Telco grade equipment • Easy to use – IMS improves User Experience based on fully integrated Services • Full connectivity – interconnection of IP service providers and their communities • Enhances Enterprise, SME and Corporate propositions • Lowers potentially the threshold cost margin for new innovative services • Reduced Break Even point allows to develop also ‘Niche Market’ Services IMTC Forum – May 2005 – Eibsee, Germany

10. IMS enabling inter-working of new IP services • Interoperability across networks and devices is essential • Consumers want ubiquitous services (e.g. telephony) not “islands”. • Successful services require network effects (Metcalfe’s law). • IP service inter-working is a key driver for service take-up and commercial success. • GSMA is conducting trials of inter-working of SIP/IMS based services • Goal: Promote interoperability of SIP/IMS-based services across providers from “day one” of commercial service. • Stakeholders: 13 companies incl. Mobile Operators (service providers), GRX Carriers (managed inter-operator backbone), IMS vendors (platform and terminal suppliers). • Achievements communicated in Cannes 2005: First tests have proven successful SIP service inter-working using real phones, IMS infrastructures of 3 vendors involved inter-working well, GRX carriers proven beneficial in enabling practical inter-working. • Plans: Two more test campaigns scheduled to run in May 2005, as more companies join. Asian operators teaming up for SIP/IMS test campaigns towards June 2005. PoC test campaign planned in 4 Q 2005. IMTC Forum – May 2005 – Eibsee, Germany

11. IMS Technical Drivers • Common layer for the Convergence of Global Services • Re-use of charging, authentication and interconnection for all Services • Allows Services to be ‘Developed once, Deployed many times’ • IMS enables the horizontal layer approach • Cost efficiency analysis indicates CAPEX & OPEX savings per service deployment • Shorter Time-to-Market • Fast and reliable service creation re-using functionalities and enablers • And more flexibility for integration of new 3rd party services • Standardised architecture developed by 3GPP • Based on IETF (SIP) & Aligned with OMA • Eases the Networks, Services & Terminals Interoperability • Supports Fixed-Mobile Convergence to facilitate a single customer touch point IMTC Forum – May 2005 – Eibsee, Germany

14. Conclusion • Services will be tailored to the user and terminal they use, not the network they are on • Packet technology is enabling convergence within and across wireless, wireline and Enterprise networks • Network and service convergence: - Provides a joined-up service meeting customer demand and expectations - Eliminates many of the costs associated with disparate and labour intensive operations • Control your IP network by yourself • Maximise revenue opportunities with the All IP ecosystem IP Multimedia subsystem (IMS) is the way forward IMTC Forum – May 2005 – Eibsee, Germany
