3 Network Generations 4/5G User Experience Immersive applications, Virtual assistants, Proactive services 3G 2/2.5G E-911 Web-access, Social Networks, , Multimedia, User- Generated Content, Maps Basic Communications and Safety 3

4 Business Model An opportunity for Providers Emergence of a new group of services are different from traditional Telco Traditional forms of communication are being displaced with message-based interactions around social community Technologies, development practices and business models are markedly different between Web 2.0 and IMS Business model based on supporting Web 2.0 application over an IMS platform can benefit end-users, service providers, and third party application developers Convergence among Web 2.0, service oriented architecture and IMS call control features Web 2.0 provides interactivity, ubiquity, social orientation and user participation IMS provides a platform to complete service features with multimedia telephony, media sharing using call control features and support for security, user authentication, quality of service 4

6 Feedback from GISFI #2 (1/2) Think beyond the operators New service providers Do not depend upon service provider always How to provide equivalent security without depending upon carrier Focus on rural India What is important (Security or QoS?) Expand business models/architectures Can this convergence framework be used for IOT? 6

7 Feedback from GISFI #2 (2/2) Gap analysis with the existing work from other SDOs is helpful to focus the work Feedback from Indian carriers will help GISFI We should try to bring carriers on board Early version of proof-of-concept should continue in parallel as part of R&D effort GISFI Liaison with other SDOs GISFI Slide 7

10 IMS SOA Web 2.0 SON Design Principles Service Experience Application Experience User Experience All three are needed Service Experience focus Illustrative Service Delivery Business Models Vertical domain integration Robust Connectivity Telco grade QoS, real-time Direct subscriber relationship Horizontal Framework User experience Mash-up Service enabled across domains Programming reuse Service Creation SON speeds up the creation of services with network robustness IT grade scalability Application Third party relationship Web grade (beta) Indirect models No support Cross domain support Evolving Trust model Built-in security model Leverages IT security model Fragmented model Challenges for Authentication, privacy and profiles SCE/SDP Intra-domain AS. Internal SDP Services built horizontally from SW Reuse Services built top Down from the user SON must foster reuse and user experience driven Service creation 10

12 Integration of IMS, SOA and WEB 2.0 IMS: Designed and developed through 3 GPP to provide telecom service over IP networks Telco Domain IMS SON SOA SOA: utilizes loosely-coupled service data exchange to implement business processes. IT Domain WEB 2.0 SON service provider domain Web Domain Web 2.0 services are typically designed using a REpresentational State Transfer (REST) programming model principle, SOAP and XML for access to data and functions GISFI Slide 12

17 Key Requirements for SON User experience matters Content and collaboration service components enrich user experience on the top of communications and sessions services Service deployment and operation is critical to establish new business models Interoperable service enablers bring strong deployment and operation properties in order to guarantee QoE across domains IMS brings interoperable roaming, authenticated multimedia calls, subscriber, network and device authentication SOA principles to ensure strong S/W principles lead to maximized quality/cost SDP/SoA brings open networks to web 2.0 enabling flexible reuse of service capabilities 7 17

18 Convergence WG objective Development of a high level framework for SON that will address How the service providers can implement the concept of SoA, Web 2.0 and IMS into their services Consistent with the unique Indian regulatory, business and infrastructure Urban and Rural India requirements Categorized into Seven Major groups General Government of India Rural India End user applications Network service enablers Underlying Network/Support capabilities Business model driven GISFI Slide 18

Transport Layer Web 2.0 has been an abrubt and disruptive change to online activity. IMS, converged services, and Web 2.0 style information represent new revenue streams for operators and further differentiates Them from dumb pipe providers. 22
