New Technology is the Easy Part(the application of it into legacy 9-1-1 cultures, well…)

Routing is a function that is performed at various levels of granularity . What SR should received the call? What PSAP should received the call? With this rationalization, several stages of ERDB/ECRF functions should be present to properly deliver a call to the proper PSAP. I3 envisioned this might be staged by country, state, county, region, municipality, PSAP (often overly simplified).

ESRP/Physical
Call DeliveryI3 is modeled to support the lowest
common denominator. Someone with a SIP phone and an internet connection (w/o a voice service provider) should be able to call 9-1-1 and reach the proper PSAP.
ALI provides a LIS function storing location for PSAP retrieval. Wireless provides a location by reference model and VSPs have implemented dynamic population of civic location addresses (postal addresses).
Direct trunking provides an equivalent
ERDB/ECRF function.
Correct set of PSAPs is
determined by physical path
from EO/MSC/PointOfOrigin
to SR.

The functions identified by NENA i3 have existed in the 9-1-1 network and have been reconstituted for new scenarios with Wireless and VoIP.

LO delivery with call setup cannot occur until devices know their locations, can transmit their locations, channels long the way to the PSAP can transport the LO, and PSAPs can accept LOs. Routing on LO requires LO determination in call processing timeframe.
Intrado STRONGLY disagrees with PSAPs receiving requests for emergency services directly from a public internet source without a responsible service provider managing receipt.
