Technical Summary

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.
