1. Technical and Policy Considerations for Unified European 1-1-2 Emergency Services Presented at EENA Brussels, 6.7 June, 2007

2. Confidential and Proprietary External Use Limited 2 1-1-2 Emergency Services Policy/Regulatory Considerations Funding –Stable and Maintainable mechanism –Even application across different technology Legislation –Lessons learned in U.S. –Cooperative agreements between countries –Timetable Jurisdictional –Single vs. Multiple ECC/PSAP deployment models –Single emergency number (1-1-2) impacts –Multiple languages supported –Boundary conditions for roaming/continuity/transfer Infrastructure –Showcase IP-based PSAP “Centers of Excellence”

3. Confidential and Proprietary External Use Limited 3 1-1-2 Emergency Services Technical Considerations to Location Standards-based Approach is Available today –Current SDO progress – (3GPP, OMA, IETF, etc.) –Protocol Development is here or progressing (Location, Routing, Data) –IP convergence – (FMC, IMS, VoIP, Internet) –Single number (1-1-2) vs. “Service Identifier” (i.e., urn:service.sos) Impacts to Location Determination –Automatic vs. Manual –Timing vs. Precision –Cell_ID vs. A-GPS –Mobility (e.g., Wireless/Cellular, WiFi, WiMax, VoIP) PSAP Routing –‘Rough’ vs. Precise Location –Low-Latency Routing (< 2 sec.) requirement? –Consolidated vs. Distributed PSAPs –Regional boundaries – impact to Roaming, PSAP Transfer Data Delivery to the PSAP –Precise location information usability –Handset-resident data possibilities –Service layer-based content (e.g., medical records, hazardous mat’ls, maps, etc.) –Reuse of data for Fire, Police, and Ambulatory

5. Confidential and Proprietary External Use Limited 5 3 Call Types, Defined: –Static Once installed at a location, it never moves (e.g., Wireline) Usually Civic (e.g., Street Address), may need validation –Nomadic Primarily Static, but may occasionally move to another location (e.g., VoIP) When moved, MUST be updated with new location Automatic location technology is moving forward in this area –Mobile Location is not fixed, but moves often (e.g., Wireless/GSM) May roam between countries May move between networks during an ongoing emergency call Utilizes precise positioning technology Represented by Geodetic coordinates (e.g., lat/lon) Subject to accuracy considerations An Emergency Service Solution for Location Determination including VoIP
