Traditional 911• ~6,000 PSAPs in the US• Selective routers route calls to correct PSAP
– Operated by carriers
– Relies on DB of fixed subscriber addresses
• Calling number (ANI) “pulsed” over CAMA trunk– 1970s technology
• Number resolved to address (ALI) through geo-DB (MSAG)• PSAPs under pressure for years to support cellular E-911
Internet 911• 911 has been a thorn in the side of VoIP• FCC 911 mandate

What Makes NG911 Hard
German Tourist
Taiwanese VSP
ISP=T-Mobile

PSAP
Rhode Island
•Mobility•ISP≠VSP•Not just “9-1-1”•Closed, proprietary legacy systems
emergency = “1-1-2”

NG911
NG911 Project• Goal: deploy proof-of-concept IP-enabled PSAPs• $1.3 million dollar, two-year project funded by NTIA, the
States of Texas and Virginia 911 offices, Cisco and Nortel• National Emergency Numbering Association (NENA)
participation
Goal of NG911 is, not only to solve VoIP 911, but to do better!
–location conveyance (with SIPPING & GEOPRIV)–emergency call identification–mapping geo and civic caller locations to PSAP–discovery of local and visited emergency dial string
