"Location-to-URL Mapping Architecture and Framework", Henning Schulzrinne, 29-Sep-07. ( bytes)

This document describes an architecture for a global, scalable, resilient and administratively distributed system for mapping geographic location information to URLs, using the Location-to- Service (LoST) protocol. The architecture generalizes well-known approaches found in hierarchical lookup systems such as DNS.

"Best Current Practice for Communications Services in support of Emergency Calling", Brian Rosen, James Polk, 3-Nov-08. ( bytes)

The IETF and other standards organization have efforts targeted at standardizing various aspects of placing emergency calls on IP networks. This memo describes best current practice on how devices, networks and services should use such standards to make emergency calls.

"Framework for Emergency Calling using Internet Multimedia", Brian Rosen, Henning Schulzrinne, James Polk, Andrew Newton, 10-Jul-08. ( bytes)

The IETF has several efforts targeted at standardizing various aspects of placing emergency calls. This document describes how all of those component parts are used to support emergency calls from citizens and visitors to authorities.

"Location Hiding: Problem Statement and Requirements", Henning Schulzrinne, Laura Liess, Hannes Tschofenig, Barbara Stark, Andres Kuett, 12-Oct-08. ( bytes)

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 end points or VoIP service providers in order to determine the correct dial string and information to route the call to a Public Safety Answering Point (PSAP). For determining the PSAP Uniform Resource Identifier (URI) the usage of the Location-to- Service Translation (LoST) Protocol is envisioned. This document explores the architectural impact for the IETF emergency services architecture 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. This document provides a problem statement and lists requirements.

"Specifying Holes in LoST Service Boundaries", James Winterbottom, Martin Thomson, 12-Oct-08. ( bytes)

This document describes how holes can be specified in geodetic service boundaries. One means of implementing a search solution in a service database, such as one might provide with a LoST server, is described.

"Synchronizing Location-to-Service Translation (LoST) Servers", Henning Schulzrinne, Hannes Tschofenig, 3-Nov-08. ( bytes)

The LoST (Location-to-Service Translation) protocol is used to map locations to service URLs. This document defines a set of LoST extensions that allow LoST servers to synchronize their lists of mappings.

"IANA Registering a SIP Resource Priority Header Namespace for Local Emergency Communications", James Polk, 27-Oct-08. ( bytes)

This document creates and IANA registers the new Session Initiation Protocol (SIP) Resource Priority header (RPH) namespace "esnet" for local emergency usage to a public safety answering point (PSAP), between PSAPs, and between a PSAP and first responders and their organizations.
