Location Hiding: Problem Statement and Requirements
Abstract
The emergency services architecture developed in the IETF Emergency
Context Resolution with Internet Technology (ECRIT) working group
describes an architecture where location information is provided by
access networks to endpoints or Voice over IP (VoIP) service
providers in order to determine the correct dial string and
information to route the call to a Public Safety Answering Point
(PSAP). To determine the PSAP Uniform Resource Identifier (URI), the
usage of the Location-to-Service Translation (LoST) protocol is
envisioned.
This document provides a problem statement and lists requirements for
situations where the Internet Access Provider (IAP) and/or the
Internet Service Provider (ISP) are only willing to disclose limited
or no location information.
