The draft itself is expired but I'll make an update once the submission is open.

Re: [DMM] DMM WG Adoption Poll (2) for "Mobile User Plane Evolution" - draft-zzhang-dmm-mup-evolution-06

[Yuya KAWAKAMI]

I respectfully disagree with the Adoption of this draft.

This document is a well organized and very good discussion of the MUP. If this
draft is Jeffery's personal one, I have nothing to say. But if it comes to WG's
Adoption, I need to provide my comment.

I agree that it would be good to combine AN and UPF into one when we pursue
the MUP architecture. There are also distributed UPF architectures for edge
computing, such as the "Distributed Anchor Point" connectivity model in
TS 23.548. This model also ultimately results in an architecture where there
are UPFs connected by short N3 segments to the gNB.

Nevertheless, MNOs are not currently using such a connectivity model and
considering "Session Breakout" connectivity model for edge computing by using
intermediate UPFs such as ULCL. It is necessary to consider the reason and
what is the barrier.

C-Plane for Mobility Handover (6.3) and Paging (6.4) are particularly important
elements in considering them, but this document does not attempt to analyze or
solve the problem and just claims that they are "the same as 3GPP's current
behavior".

You mentioned that this document can be an input from IETF to 3GPP after the
WG adoption, but reviewing this document from 3GPP's point of view, I'm sorry
to say that there is no insight to be gained from this document.

I feel that it is necessary to consider the C-Plane (Satoru's point (1) and (2))
as Katsuhiro says and clarify what has changed in transport network technology
to make this ANUP feasible since the days when the central PSA UPF model had
to be deployed.
