I think the draft is worth more review, which I will commit to provide as well.

I don’t have any further review comments, but it needs A LOT more work to progress.  I’ve discussed issues with Sri off line and committed to review and assist with making it work from the emergency call side if it progresses,

I personally don’t know how useful the idea is.  I can’t get my head around how the pieces would come together.  The document and the authors seem to waffle on exactly who is providing the SIP call interface.  If it’s a 3rd party IMS network authorized by a regulator to provide this service (under some unknown compensation scheme), which seems to be at least part of the idea, then the client is a 3GPP compatible device, and it needs an eSIM or something like it so it can roam to this emergency IMS network.  I think in fact it would require code changes in the device to make that really only work if you tried to place an emergency call, but maybe not. While I kind of see how that might work, I fail to see a real deployment path.  If some other entity provides the SIP proxy server then there is a whole lot of unspecified mechanism but maybe that is more deployable.

However, if it progresses, ecrit would be the place to do it for sure, and I think it’s within our charter.   If not quite, I’m sure some very small change could accomodate it.

ECRIT WG,

There's been no further feedback on this document.  There was quite a bit that got it from -00 to -01, but nothing since.  So I have two questions:
(1) Are there any further review comments on the document irrespective of its status; and
(2) Is this work ECRIT sees as being within its charter, or near enough that we should consider a charter adjustment to accommodate it?  If not, are there any suggestions about where and how this should be processed?

Dear All,


We have revised the draft based on all the feedback received from Brian, Dale, Roland, Christer and others. I still have to change the filename to make it not specific to one regulatory domain, but its reflected in the text. I will request the IETF secretary to change the filename. Please review and provide any feedback. Appreciated!

Abstract:
This document introduces an approach to enable emergency services
over Wi-Fi access networks. These services encompass emergency
services such as 911 in North America, 112 in the European Union, and
equivalent emergency services in other regulatory domains. The
proposed approach aims to provide a comprehensive solution for
supporting emergency communication across different regions and
regulatory frameworks.








Leveraging the legal framework and infrastructure of the OpenRoaming
federation, this proposal aims to extend emergency calling
capabilities to the vast number of OpenRoaming Wi-Fi hotspots that
have already been deployed.








The approach addresses critical challenges related to emergency
calling, including discovery and authentication procedures for
accessing networks that support emergency services, emergency access
credentials, the configuration of emergency voice services, accurate
location determination of the emergency caller, and call spofing.








By providing a comprehensive solution, this proposal ensures that
emergency communication services can be seamlessly and effectively
supported within the IEEE 802.11-based Wi-Fi ecosystem leveraging
Passpoint Profiles.
