Agenda

• VoIP Adopts the Wireless E9-1-1 Model

• VoIP – A Challenging Environment– The Current VoIP Models– Location: The Toughest Challenge– Other Key Issues to Address

• What Happens when Technology Fails?• How to Test without driving Public Safety Crazy• Pay Attention to Liability

• Solutions Being Tested & Deployed

VoIP Adopts

the Wireless E9-1-1 Model

5


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


• 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


• 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

The Toughest

VoIP Challenge:

Location

14


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


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


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


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


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

• 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!!

PSAP Outreach Efforts• Education & information exchange w/ 3000+ PSAPs nationwide

Applying Wireless Mobility to VoIP

25


Nationwide Deployment Progress

• TCS is aggressively deploying PSAPs– In support of Vonage– In support of customers of Level(3)

• Thousands of PSAPs have received information• Thousands of PSAPs have provided information• Hundreds have been deployed• ALI connections in place• Selective Router access by Level(3) & others• Rapidly provisioning ESNs and ESQKs

– Testing EVERY ESQK

Summary

• Evolution is the first step (following wireless)

• VoIP – A Challenging Environment– Models exist and are being implemented– Location is the toughest technical challenge– Other Key Issues to Address

• Have a fall-back scenario to handle failures• Have a test platform that does not impact the PSAP• VoIP providers are exposed to liability – be aware!

• Nationwide VoIP E9-1-1 Rollout Continues!!
