VoIP Adopts
the Wireless E9-1-1 Model
5
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
Requirements for a proper E9-1-1 call:
1. Must know location of caller
2. Must use caller location to route call • The US has over 8000 Public Safety Answering Points (PSAPs)
• PSAPs typically cover metropolitan areas or counties
• PSAPs are Call Centers which dispatch Emergency Services
3. Must deliver caller location• Call Centers can automatically receive location information
• For wireline & VoIP, street address information is delivered• For wireless, latitude/longitude information is delivered
1 [Location] + 2 [Routing] + 3[Delivery] = Full E9-1-1!

The Current
VoIP E9-1-1 Models
9
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
• Voice over IP (VoIP)– Voice transmitted as data over IP transport– Three broad categories of service:
• Static VoIP: to the home as a wireline replacement• Nomadic VoIP: person stops in different places• Mobile VoIP: continuous movement within VoIP network
• Challenges:– [1] How to locate?– [2] How route?– [3] How deliver?
VoIP Presents E9-1-1 Challenge

10
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
• I1 – routing to PSAP administrative line– This is “Basic” 9-1-1 – not “Enhanced” E9-1-1– Requires geospatial boundary maps for PSAPs nationwide
• I2 – use existing E9-1-1 infrastructure– True “Enhanced” E9-1-1– Requires same as I1 and also access to Selective Routers
• I3 – use VoIP in the end-to-end delivery model– True “Enhanced” E9-1-1– Requires boundary maps but NOT selective routers– PSAP uses VoIP in their response systems– VoIP call the whole way
Phased Approach for VoIP E9-1-1

The Toughest
VoIP Challenge:
Location
14
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
Automatic Location: Port Discovery
• Port identification & discovery– System identifies ports in use– System interrogates devices attached to ports– Port mapped to telecom identifier– Administrator can map port to a specific location– Done for PBX systems today
• Helps business meet FCC E9-1-1 MLTS requirements• Updates submitted daily – activated w/in 48 hours
– VoIP implementations will change more rapidly• 48-hour delays will impact progress on MLTS issues
– Excellent for Enterprise applications
15
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
Automatic Location: Triangulation
• WiFi triangulation techniques– Triangulates on attached devices– System interrogates devices attached to ports– Interacts w/ client software on device– Accuracy demonstrated within 3 to 5 meters– Excellent for enterprise applications
16
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
Automatic Location: GPS
• GPS Triangulation Techniques– Integrated into WiFi device– Interacts with visible satellites for multi-point triangulation– Same technology as in current wireless handsets– Accuracy under 5 meters in many scenarios– Excellent for consumer applications
17
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
Automatic Location: TV-GPS
• TV-GPS Triangulation Techniques– Integrated into WiFi device– Interacts with TV towers for multi-point triangulation– Same technology– With three connections, can triangulate within 1 meter– Excellent for consumer and enterprise applications
18
January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
Automatic Location: WiFi Mapping
• Mapping of WiFi Hot Spots– Handset identifies WiFi connection point
• Over 70 major metropolitan areas mapped– Thin client communicates IP address to Mapping Server– When 9-1-1 is dialed, TCS interrogates Mapping Server– Accuracy within 30 meters or better – Currently able to provide live demonstrations– Excellent for consumer or enterprise applications

January 24-27, 2006 • Ft. Lauderdale, FL • www.itexpo.com
• Public Safety is demanding E9-1-1– The customer base expects it– The FCC has mandated it
• Regulations protect Competitive LECs (CLECs)– Most states provide liability protection– Extends to wireline, wireless, and CLEC
• Not all VoIP Service Providers are CLECs– Some wish to avoid the regulatory environment– Unfortunately, they miss the regulatory protections
You May Be Unprotected!!
