   Extensions to the Emergency Services Architecture for dealing with
                Unauthenticated and Unauthorized Devices
             draft-ietf-ecrit-unauthenticated-access-09.txt

Abstract

   This document provides a problem statement, introduces terminology
   and describes an extension for the base IETF emergency services
   architecture to address cases where an emergency caller is not
   authenticated, has no identifiable service provider, or has no
   remaining credit with which to pay for access to the network.
