7. Copyright 2006: MultiService Forum 7 Industry Impact of GMI 2006 Theoretical-to-Practical Migration –The GMI events are extremely beneficial to both carriers and vendors because they move deployment and interoperability issues out of the theoretical realm into the practical world. –All participants and even observers come away with a much more realistic view of what it will take to build a next-generation network. Relationship Building –GMI 2006 event is as a dress rehearsal for the opening night of what may be the next- generation multi-vendor service delivery platform. Valuable Feedback loop –The GMI creates a tremendous information source that participating companies can feed back into their engineering and product development activities. –Information gleaned from the GMI event can also be fed back into the standards bodies to refine specifications and achieve greater insight to the theoretical portion of the IMS development cycle. Serves collective Interest of Telecommunications Industry –Solving the IMS puzzle, that is moving IMS from a collection of theoretical functional modules to a physical network architecture, is in the interest of the entire industry.

12. Copyright 2006: MultiService Forum 12 GMI 2006 Physical Scenarios Scenario 1 - Single Domain with nomadic subscribers. Includes both terminal and subscriber nomadicity. Scenario 2 - Single Domain, nomadic subscribers with Value Added Services. Builds upon Scenario 1 adding in SIP and Parlay/OSA applications. Scenario 3 – IMS interconnection between subscribers in the MSF R3 domain and ‘pure’ IMS domain. MSF R3 and IMS appear as peer IMS networks. Scenario 4 – Roaming of subscribers between MSF R3, ‘pure IMS’ and MSF R3 networks. Roaming includes both terminal and subscriber mobility. Scenario 5 – Roaming of subscribers between MSF R3, ‘pure IMS’ and MSF3 networks. Includes both terminal and subscriber mobility. Scenario 6 – Management. Provisioning of Multi Technology Inter-site VPN’s. Value Added Services –VoIP/IMS and fault management.
