5.      MSISDN and privacy
6.      MNOs as single, virtual IDP or autonomous IDPs/ Mobile phone number portability


·         A special call to be organized next week (John, Bjorn, Joerg) regarding structure of 3 docs (overview, abstract...)

·         Use Case doc to work on

·         Continue discussions on the mailing list


1-      Status of document split (John, Bjorn, Jörg)
Questionning on the structure of the documents, a call to be organized next week to fix it.
2-      Status of use case outline (Tim)
Do we have to discuss of this Use Case live or on the mailing list ? the discussion will take place on the mailing list

3-      Discussion around the MSISDN, discovery and privacy
Comparisons of MSISDN usage and email address usage. People are not reluctant to enter their email address on a RP page.
Account chooser is mentioned as a help for the user and the RP, discussion around this tool.

4-      Other projects
Pilot in Germany occurring under OpenID Connect with major MNO, MVNO and one partner. Complexity to cope with different MNO IDM and few OIDC implementations. Discovery function could rely on mobile-profile WG deliverables

5-      MNOs as single, virtual IDP or autonomous IDPs/ Mobile phone number portability
If we want the task to be simple for developers, we have to consider one RP addressing one virtual MNO IdP. On the other hand, putting a kind of proxy in the chain (to mask the complexity of different MNO IdP) will strongly complexify the scope on technical and probably legal grounds.
John mentions account chooser as a tool to facilitate the MNO discovery
Questions about the software statement and its global provisioning. API back to the original statement provider ?

Kind regards,
