2. The Business Challenges The successful carrier will have to: • Grow and protect subscriber base, increase ARPU • Deliver a differentiated portfolio of value-added services • Maximize ROI while controlling OPEX • Invest in open systems, standards-based solutions to remain competitive • Enhance capabilities of legacy systems if necessary • Focus on application services • Rapidly develop and deploy new services, including video • Develop on standards-based technology • Reduce time to market for new applications using web development model

3. Hosted Services Voicemail Conferencing Video Messaging Gaming Let’s Talk Services • Applications deliver Services • Services area set of capabilities offered to customers • Must be able to bill for services …and many more

4. IMS – Building the Foundation • Converged Application Service Architecture • Separate Transport, Service Control and Applications Layers • Fixed-Mobile Convergence on One Common IP Application Services Architecture • Open, Standards-based • Standards-based Protocol Interfaces (SIP+XML) for Flexible Integration & Control of New Services • Not API’s that Bind to Operating System, Device Control Development Model • Facilitates Service Creation Environment IMS is all about applications, built on IP and SIP

5. Hosted Services Voice Text Win Media Video MP3 Data IMS Simplified Network View • Converged Applications • Across Networks • Reduced development costs and time • Voice, Video and data services • Write once / use many Applications Web Content • Shared Resources • Media server resources • Common user data • Single user profile across applications • Integrated applications Call Session/Control SIP Transport • Session Control • Common Session Control (SIP) • Provides common service policies • Leverages investments across multiple • applications Access Network • Access Network Agnostic • Eliminates multiple service solutions • Network transparency • Consistent services across networks DSL PSTN Mobile CMTS

6. Why IMS • IP will continue to be a disruptive technology to traditional telecom operators and is transforming business models from voice-driven to service-driven • Facilitates cap and grow approach • Operators require more applications to meet competitive threats • CAPEX and OPEX pressures are constant • Operators need a better environment for creating and deploying high value rich multimedia services • Service delivery velocity • Lower cost standards-based platforms • Controllable, yet open environment for service creation & delivery

7. Customer Case Study Video Messaging IMS Subsystem: A/S and MRF SIP SIP 3G/IMS Handset 3G/IMS SIP Application Server LDAP Directory RTP SIP/ VoiceXML H.324M UMTS H.324M to SIP Gateway RTP 2.5/3G Video Handset HTTP SIP Message/ Content Store Media Server RTP Internet SIP Broad- band PC with SIP soft phone

8. IMS Benefits • Efficient Resource Utilization • Standard interfaces allow multi-network interoperability for user to user interactions and content distribution • Access Network Independence • Content storage medium can be off line processed into various formats • Shared Resources • Lower Development Cost and Faster Deployment • Modern, Proven Development Techniques • Less Lines of Code to Write, Less Complex Code = Less Errors • Environment That is Familiar to Large Developer Pool (HTTP, HTML, and XML, etc) • Off the shelf hardware – software available from a more general development pool
