convergence of IT and Telco taking place.
�MPHASIS will study a few set of information
models as defined in TM Forum and will take into
account a specific application such as wireless number portability (WNP).
�The deliverable format could be a word document
and set of annotated view graphs.

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
�NIKSUN represented GISFI SeON during October ATIS SON meeting in Washington DC
�ATIS shared their work plan document for GISFI members
�Cloud computing is now part of SON
�Dialogue in progress to have an official collaboration with ATIS
�GISFI as an affiliate member

�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
