5 How do operators transfer ported number files? (E.g. Not call flow) FTP ONO FTP DNO Web or API RNO DSP SPI Web MNP System OSG/Syniverse Web SPI RSP I want to leave you I want to join you Customer

6 Overall MNP process Mobile Network Operator Mobile Service Provider MNP OSG MNP ORG MNP OTG MNP Porting Files Bilateral Agreements with each MNO & MNRH OSG MNP Web System MNP Web System is: Owned by the 5 MNOs Operated by Syniverse Controlled by the OSG MNP Settlement New Mobile Number Range Holder Mobile Service Provider

7 Current Billing relationship for ported number Originating Network Call to Ported Number Mobile Number Range Holder Network (ONO) Call to Ported Number Destination Network (RNO) Payment = MTR of Range Holder Network Payment = MTR of Range Holder Network less Donor Conveyance Charge (0.8 ppm)

8 MCom MNP Experience - History Ofcom auctioned gsm/dect guard band spectrum April 2006 MNC, Number block, point codes A normal mobile service when in range of service (localised gsm) Request Interconnect Voice delay even when BT transit What obligation to data fill? SMS No transit? BT switches not sufficient CPU MNP OSG controlled asset quasi cartel, non incorporated body, easy to veto All new Mobile Number holders advised by Ofcom to join the MNP OSG to meet their GC18 obligations for MNP however all applications refused Largest and smallest join and approach Ofcom December st group discussion Numerous point-of-principle grandstanding, H3g refuse to play until SMP imposed - OSG deadlocked Chicken and egg on numerous issues Unreasonable costs for low porting volume

9 MCom Experience - Current New constitution drafted (painful process) Constitution (as of today) not yet enacted by major MNO s New constitution creates two tier system System owners who empower Syniverse to commercially offer access to others Participating Members Participating members pay to use system on per port basis, with minimum monthly cost OSG Technical Work group Use of SFTP instead of FTP/ISDN for file transfer SS7 hub review, review of Sigtran as option Project Plan at least four months behind schedule Syniverse begin adding first batch of new entrants to system

10 UK MNP - Outlook At some point in 2008 first new entrant applications for MNP will come to fruition BT will be first as they have existing TDM connections Until major MNO s migrate to SS7/IP (Sigtran) legacy E1 s will be required for interconnect if hub rejected New entrants likely to support Sigtran from outset Awaiting outcome of current Ofcom consultation on new porting timetable Direct routing on horizon MNP OSG will need to dovetail to overall UK porting
