Miya “ANUP solely addresses user plane convergence and tries to liaise with 3GPP, but I'm afraid this is a half-baked attempt.”
Absolutely agree and there are many aspects of the current 3GPP design which are not very ‘IETF-like’ that we should be considering (removal of IMS and total separation of the voice/text service from the transport network would be the first item I’d consider – then move onto the use of tunnels, then look at authentication, then at a truly global-mobile solution… etc.) So this draft is good but I agree it only really addresses the ‘here-and-now’ and we have much in the control plane that needs reworking. What I think we need in IETF (and it is not in a chartered group such as DMM – that scope is known) is a study of the current ‘mobile’ infrastructure with reference to how today’s consumers are using it predominantly for Internet access (a good thing for IETF and that includes voice and text which is mostly OTT now) and whether the current economic and architectural models fit that use case. Where I struggle is that is probably not an IETF WG or IRTF RG.

In fact, RAN Core convergence has already been discussed. e.g. https://ieeexplore.ieee.org/document/10073488 https://ieeexplore.ieee.org/document/10001281 ANUP solely addresses user plane convergence and tries to liaise with 3GPP, but I'm afraid this is a half-baked attempt. The MUP[*] assumes no change to 5GC, and I think IETF DMM should focus on this at least for the time being.
