1. Emergency Communication over IP Matt Lepinski mlepinski@bbn.com

2. 2 Outline What is Emergency Communication (EC)? l Citizen-to-Authority Communication l Authority-to-Citizen Communication Why EC over IP? How might EC over IP work? l Examples What is required to do EC over IP? l Location l Standardized Interfaces to Location Whos working on EC over IP? How can you learn more about EC over IP?

3. 3 What is Emergency Communication? Citizen-to-Authority l Calls routed to the nearest police/fire/medical dispatcher l 1-1-2 on GSM phones and in Europe l 1-1-1 in New Zealand l 9-1-1 in North America Authority-to-Citizen l Geographically targeted disaster warnings l Earthquake, Tsunami, Hurricane, etc

4. 4 Why EC over IP? A growing number of mobile devices support IP l iPhone, 3GPP, Blackberry, etc People are using Laptops in more and more places l Hotels, coffee shops, convention centers, etc VoIP and Real-Time Text Messaging are growing l Skype, Google Talk, Vonage, etc Goal: Any IP-device on any network can request help or receive warnings anywhere in the world

5. 5 Citizen-to-Authority Example Location Server Location to Service Mapping Database Routing Element Emergency Dispatcher location signaling w/ location signaling w/ location media reference to dispatcher location

6. 6 Citizen-to-Authority Example Location Server Location to Service Mapping Database Routing Element Emergency Authority location reference signaling w/ location reference signaling w/ location reference media reference to dispatcher location reference location de-reference location de-reference

7. 7 Authority-to-Citizen Example Location Server Location to Service Mapping Database Emergency Authority location Register Alert reference to authority

8. 8 Authority-to-Citizen Example Location Server Location to Service Mapping Database Emergency Authority location Register Alert reference to authority Network Element Alert

9. 9 Whats required to do EC over IP? Location l Location is required to route emergency requests, and to determine which alerts to deliver l Access network has a key role in locating a device E.g. Network topology data to locate wired devices E.g. GPS-assist or Wi-Fi triangulation data to locate wireless devices l Good News: Other non-emergency services are also driving location Location-based advertising How do I get to the nearest grocery store? Which of my buddies are nearby?

10. 10 Whats required to do EC over IP? Standardized Interfaces to Location l A device needs a small number of mechanisms to obtain either its location (or a reference to its location) E.g. DHCP, HELD, SUPL, etc l An access network needs to provide location (or location references) via one of these mechanisms l Applications need to an API that provides location l Emergency Authorities need a standardized format for location

11. 11 Whos working on EC over IP? Standards Bodies l IETF (ECRIT and GEOPRIV) l 3GPP, 3GPP2 l OMA (Open Mobile Alliance) l OGC (Open Geospatial Consortium) l Wi-Max Forum l ETSI TISPAN l OASIS

12. 12 Whos working on EC over IP? Emergency Services Workshop Series l Every 6 months since October 2006 Next workshop is October in Vienna, Austria l Broad participation from Europe and North America Standards Developers Regulators Network Operators Emergency Services Operators l Seeking participation from the Asia-Pacific Region Trying for 2009 workshop in this region l Goals: Standards alignment between standards bodies Standards that meet the needs of all stake-holders
