Extensions for Unauthenticated and Unauthorized Devices

The draft document titled "Extensions for Unauthenticated and Unauthorized Devices" discusses protocols for handling emergency service calls from devices that cannot authenticate. It outlines the framework and processes required for these scenarios while maintaining the integrity of emergency communications. The latest updates include an improved structure, clarifications, and editorial enhancements, without introducing major technical changes. A flow diagram has been incorporated to illustrate the call initiation process clearly. The relationship with ecrit-direct and differences in scope are also highlighted.

  1. Extensions for Unauthenticated and Unauthorized Devices draft-ietf-ecrit-unauthenticated-access-01 H. Schulzrinne, S. McCann, G. Bajko, H. Tschofenig, D. Kroeselberg

  2. Document Status • Draft is now WG item, former draft-schulzrinne-ecrit-unauthenticated-access. • In the latest update, we • rearranged/restructured the text and added some clarifications • did numerous editorial updates • slightly reworked the definitions • did not introduce any major technical changes IETF #77, ECRIT WG

  3. A Flow Diagram has been added for clarity Start Credentials available? no yes Waiting for ES callinitiation Lower-layerattach ASP configured? Emergency NW attach possible? yes no no yes PhoneBCP NASP NAA Authorized? no yes ZBP PhoneBCP IETF #77, ECRIT WG

  4. What about ecrit-direct • Relation between this document and ecrit-direct came up at IETF-77(?): • ecrit-unauthenticated covers “unauthenticated” cases in general (see above diagram) • ecrit-direct only covers ASP-less cases (maps to NASP), scope more limited compared to ecrit-unauthenticated. • There should not be any major conflict • Some differences: Ecrit-unauthenticated… • does not assume mandatory LOST support (ESRP discovery via DHCP as fallback) • Does not propose a detailed solution for NASP cases (e.g. no callback considerations) IETF #77, ECRIT WG

  5. Next steps Document considered ready for WG last call. IETF #77, ECRIT WG
