"LoST: A Location-to-Service Translation Protocol", Ted Hardie, Andrew Newton, Henning Schulzrinne, Hannes Tschofenig, 28-Mar-08. ( bytes)

This document describes an XML-based protocol for mapping service identifiers and geodetic or civic location information to service contact URIs. In particular, it can be used to determine the location-appropriate Public Safety Answering Point (PSAP) for emergency services.

"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, 25-Feb-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, 25-Feb-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.

"A Dynamic Host Configuration Protocol (DHCP) based Location-to-Service Translation Protocol (LoST) Discovery Procedure", Henning Schulzrinne, 11-Jul-07. ( bytes)

The Location-to-Service Translation Protocol (LoST) describes an XML- based protocol for mapping service identifiers and geospatial or civic location information to service contact Uniform Resource Locators (URLs). LoST servers can be located anywhere but a placement closer to the end host, e.g., in the access network, is desireable. Such a LoST server placement provides benefits in disaster situations with intermittent network connectivity regarding the resiliency of emergency service communication. This document describes how a LoST client can discover a LoST server using the Dynamic Host Configuration Protocol (DHCP).
