   The IETF emergency services architecture assumes that the calling
   device has acquired rights to use the access network or that no
   authentication is required for the access network, such as for public
   wireless access points.  Subsequent protocol interactions, such as
   obtaining location information, learning the address of the Public
   Safety Answering Point (PSAP) and the emergency call itself are
   largely decoupled from the underlying network access procedures.

   In some cases, however, the device does not have these credentials
   for network access, does not have a VoIP service provider, or the
   credentials have become invalid, e.g., because the user has exhausted
   their prepaid balance or the account has expired.

   This document provides a problem statement, introduces terminology
   and describes an extension for the base IETF emergency services
   architecture to address these scenarios.
