The IESG has approved the following document: - 'Extensions to the Emergency Services Architecture for dealing with Unauthenticated and Unauthorized Devices' (draft-ietf-ecrit-unauthenticated-access-10.txt) as Informational RFC This document is the product of the Emergency Context Resolution with Internet Technologies Working Group. The IESG contact persons are Richard Barnes and Alissa Cooper. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ecrit-unauthenticated-access/ 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. Working Group Summary This document represents strong work group consensus and broad group participation in developing the solution provided. There were no significant controversies that were not overcome during the development stage. A successful document development history is documented in the ecrit email list archive. Document Quality No existing implementations are known to exist. Several vendors were involved in sponsoring the document originally, and have stayed involved in the development and review of the document.
