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
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.
