In miD-JUne 2011, the National Emergency Number Associa- tion (NENA) approved the end- state architectural vision for Next Generation 9-1-1.6 The
“i3” architecture, as technical experts
call it, presents a detailed architecture
for key elements of the next-generation
9-1-1 systems, describing how networks and devices will eventually work
together to enable voice, text, image,
and data exchange between citizens
and first responders.
It took NENA members years to
complete the work on the i3 architecture and related specifications.
Although NENA is the leading emergency services organization in North
America, it did not develop the specifications alone. The i3 architecture
borrows heavily from the standards
developed by the Internet Engineering
Task Force (IETF) on SIP, location, and
emergency calling. It is not only the reuse of specifications that is significant
but the mind-set acquired by NENA
from the IETF: IETF’s emergency ser-

vices architecture follows the Internet
application deployment model where
applications may be provided by com-
panies that are different than those
providing Internet access. This as-
sumption may not necessarily be sur-
prising for Internet and smartphone
application designers, but it is a signif-
