Andy, Henning, Marc - The NENA requirements for i3 are publicly available
on the NENA website, www.nena.org, under
Technical Requirements Documents. You will find that this document addresses
emergency call routing and location validation as separate functional elements.
You will not find any requirements related to the physical implementation
of these functional elements (i.e., the TRD does not make any statements about
whether these functions should be implemented together or separately). You
will not find a requirement that says that the location validation function
requires the return of a URI. Terry From: Andrew Newton

(I'm still unsure as to why
separating the two functions would be a good idea, but that's a separate
discussion.) Actually, that is a good question. We seem to be taking stabs in
the dark regarding the satisfaction of some NENA requirements that are, to my
knowledge, not publicly available. If NENA wants the IETF to create a
protocol that meets its requirements, they need to make the requirements
publicly available. And I can't help but wonder why the separation of the validation
function from the mapping function is such a big deal. My understanding
was that validation required mapping, which means returning the URI.
Otherwise trying to determine if a particular civic address is mapping to the
proper PSAP would be difficult. -andy |
