6 Business Model An opportunity for the Operators 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 6
7 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 7
8 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 8

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
13 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 IT grade scalability Application Third party relationship Web grade (beta) Indirect models No support creation of services with network robustness 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 13
14 Different Standardization domains Web clients REST APIs WEB 2.0 User domain IMS Clients SOA Main stream commercial apps User End users Service Applications Re-Use SDKs APIs Service Enablers Many long-tail apps and developers SOAP APIs Resource Few apps and developers IMS Applications Storage and computing Networks Web domain Telco domain IT domain GISFI Source ATIS Slide 14

16 Possible Areas of work Investigate New business models for SON Control and configuration management Context aware and self organizing network Pervasive Network Architecture Telecom Network Virtualization Service Creation Environment Third party service enablers Information migration End-to-end QoS provisioning Seamless mobility End-to-end Security Green Telecom (SoN) Co-existence with legacy applications GISFI Slide 16
17 Integration of WEB 2.0 application in IMS: a Case study S-CSCF Existing (USP) SIP A/S (SIP msg unpacked, re-emitted as HTTP) P-CSCF HTTP Response SIP 200 OK Internet HTTP message SIP:REGISTER SIP:MESSAGE(event data) Google, Yahoo! API s Web Application Server USP Logic (JSP s) HTTP Get Web Browser SIP client SIP message formation tool Event emulation/emission Send(SIP msg) Create SIP msg from XML event User views her web-based portal 17
18 Copyright 2008, Telcordia Web 2.0 Applications over IMS Case study Contextual Mashup logic IMS Layer AS Application-Service Layer Transport Layer -Tomcat - Event Engine AS AS Outbound reminders AS Events (in SIP message) Mobile user and other applications push and pull context towards the Application Server (AS). Context is embedded in SIP messages. Context might be GPS coords,, new scheduled events or new directives. Mashup logic continually updates users information layer, providing notifications of calendar, task and other information deadlines. 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. 18
19 Self Organizing Network Self Organization of IMS Goals of Self Organization of IMS Efficient Redundancy Easy Planning of facilities, Easy Configuration How to realize Each Node recognizes required roles automatically ex.

SON (Service Oriented Network) * SeON (Service Oriented Network) - Accepted as the new WG name GISFI SON (GSON) SONG (SON from GISFI) * SANGAM - Possible architecture name Convergence for SON (CSON) Service Oriented Converged Networks Service Convergence (SeCON) 24
25 Conclusions 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 25
