Abstract

The general Emergency Context Resolution with Internet Technology (ECRIT) calling models described in [RFC6443] and [RFC6881] require a local Location-to-Service Translation (LoST) server or network of forest guides in order to determine the address of the Public Safety Answering Point (PSAP) in the best position to handle a call. Networks of forest guides have not materialized and while PSAPs are moving towards IP networks, LoST server deployment is not ubiquitous. Some regions and countries have expressed reluctance to deploy LoST servers making aspects of the current ECRIT architecture hard to realize.

                     A Routing Request Extension for            the HTTP-Enabled Location Delivery (HELD) Protocol

Abstract

   For cases where location servers have access to emergency routing    information, they are able to return routing information with the    location information if the location request includes a request for    the desired routing information.  This document specifies an    extension to the HTTP-Enabled Location Delivery (HELD) protocol that    updates RFC 5985 to support this function.  Allowing location and    routing information to be acquired in a single request response    exchange updates RFC 6881, as current location acquisition and route    determination procedures are separate operations.
