Hello Seil,

Please excuse my delay for this clarifying comments. I have been immersed elsewhere.

In order to be as clear as possible, please let me refer to a couple of diagrams. Slide 5 of your presentation at IETF 101 was entitled "Model-5: On Demand Control Plane Orchestration Mode".

A URL is: https://datatracker.ietf.org/meeting/101/materials/slides-101-dmm-dmm-deployment-models-and-architectural-considerations-01.

And then we have various representations of 3GPP architectural diagrams for 5G. For instance, one can look at slides 4-6 of K. Bogineni et al.'s presentation.

A URL for the latter is: https://datatracker.ietf.org/meeting/101/materials/slides-101-dmm-optimized-mobile-user-plane-solutions-for-5g-00

My suggestion was to try to correlate the two different representations of advanced mobility management architectures. This would involve making a correspondence between the [dmm] nomenclature (e.g., H-CPA, A-CPN, etc.) and the 3GPP nomenclature.

Hi Charlie,

Thanks for your comments on our update of the I-D.

You commented and suggested that 5G functions in TS 23.501 need to be mapped with the CPA/CPN, DPA/DPN introduced in our I-D.

I know you have additional suggestions. Will you specifically mention, please?

Regards,

Seil Jeon

Overall Description: 3GPP working group of CT4 (Core and Terminal) would like to inform the IETF that CT4 has initiated a study item on user plane protocol in 5GC for Release-16 of 5G phase 2 (see CP-173160). Based on the outcome from the IETF / 3GPP Coordination meeting at IETF#100, 3GPP CT4 got aware that IETF DMM WG is currently working on a possible candidate protocol for the 3GPP 5G user plane protocol. 3GPP CT4 wants to emphasize that currently there is no related evaluation ongoing in 3GPP. Nevertheless, a study item was approved for such a study to start in the second half of 2018. The study will evaluate between existing solutions within 3GPP and other protocols, based on the Release 16 stage 2 (system architecture) requirements. 3GPP CT4 would like to point IETF DMM to the following specifications on GTP-U. The Release 16 stage 2 requirements are not yet known but it is worth looking at latest GTP-U spec which will be evaluated through the study as the existing protocol. • [1] 3GPP TS 29.281 (V15.1.0): GPRS Tunnelling Protocol User Plane (GTPv1-U) Following technical report provides information of how 3GPP considered GTP-U apply to user plane of 5G_ph1: • [2] 3GPP TR 29.891 (V15.0.0): 5G System – Phase 1; CT4 Aspects Furthermore, 3GPP would like to give the following general guidance to IETF DMM, regarding user plane transport within 3GPP networks. These are technical specifications that include also the necessary information to understand which architectural, QoS, security-related and high-level requirements GTP-U currently complies to within 5G_ph1. • [3] 3GPP TS 23.501 (V15.0.0): System Architecture for the 5G System • [4] 3GPP TS 23.502 (V15.0.0): Procedures for the 5G System • [5] 3GPP TS 23.503 (V15.0.0): Policy and Charging Framework for the 5G System • [6] 3GPP TS 33.501 (V0.6.0): Security Architecture (work in progress) 2. Actions: To IETF DMM: ACTION: CT4 respectfully asks IETF DMM to provide any information that may be relevant to the above CT4 work by July 2018. 3.

Working Group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 13 Apr 2018 21:33:15 -0000 Hello folks, The liaison statement seems to suggest that the existing work in 3GPP is either to develop the 5G architecture, or to see how well the current evolution of GTP-U fits the 5G architecture as developed.  It is natural to also expect that the thinking about the 5G architecture has been influenced by the known behavior and features of GTP-U.  The further guidance in the Liaison statement seems to recommend familiarity with 23.50{1,2,3} and 33.501. I've had a look at some of the documents, and they can be pretty heavy sledding. draft-bogineni-dmm-optimized-mobile-user-plane-00 is somewhat more compact.  And yet it also focuses a lot of attention on SMF as well as UPF. Is the IETF expected to make comments only about UPF? Some previous discussion suggested that whatever UPF would be developed in the IETF, needed to be independent of the control plane.  But presumably 3GPP would like a UPF that offered the control features that are required for SMF as well.  That's a lot of additional features.  It seems to place additional constraints on whether or not an IETF user-plane protocol would be useful for 3GPP. If the task is only to provide information to 3GPP about what [dmm] is doing, then the task is manageable.  But if we are also required to describe how an IETF user-plane protocol meets or does not meet the requirements in {2,3}3.50{1,2,3} -- that's a difficult task. Moreover, the charging framework has usually been considered outside the jurisdiction of IETF if I remember correctly -- something about anti-trust. Regards, Charlie P.

This draft is a work item of the Distributed Mobility Management WG of the IETF. Title : Proxy Mobile IPv6 extensions for Distributed Mobility Management Authors : Carlos J. Bernardos Antonio de la Oliva Fabio Giust Juan Carlos Zuniga Alain Mourad Filename : draft-ietf-dmm-pmipv6-dlif-00.txt Pages : 32 Date : 2018-04-18 Abstract: Distributed Mobility Management solutions allow for setting up networks so that traffic is distributed in an optimal way and does not rely on centralized deployed anchors to provide IP mobility support. There are many different approaches to address Distributed Mobility Management, as for example extending network-based mobility protocols (like Proxy Mobile IPv6), or client-based mobility protocols (as Mobile IPv6), among others. This document follows the former approach, and proposes a solution based on Proxy Mobile IPv6 in which mobility sessions are anchored at the last IP hop router (called mobility anchor and access router). The mobility anchor and access router is an enhanced access router which is also able to operate as local mobility anchor or mobility access gateway, on a per prefix basis. The document focuses on the required extensions to effectively support simultaneously anchoring several flows at different distributed gateways. This document introduces the concept of distributed logical interface, which is a software construct that allows to easily hide the change of anchor from the mobile node.

I think it is a few years late, it should have been around already. Nevertheless, I view it is a positive that now we have this work. I suggest change the title to the dmm protocol reduce the number of acronyms, some of them pretty confusing like CMD finalize it as quickly as possible call it quits.

Hi all,

I looked through this draft and= my initial reaction is that I think that this draft corresponds to what I = called the dmm protocol in my mail a few weeks ago.

I think it is a few years late, it should have been around already.
=
Nevertheless, I view it is a positive that now we have this work. I su= ggest=C2=A0
change the title to the dmm protocol
reduce= the number of acronyms, some of them pretty confusing like CMD
f= inalize it as quickly as possible
call it quits.

Regards,
Behcet

Abstract:
=C2=A0 =C2=A0Distributed Mobility Management solutions allow for setting up=
=C2=A0 =C2=A0networks so that traffic is distributed in an optimal way and = does
=C2=A0 =C2=A0not rely on centralized deployed anchors to provide IP mobilit= y
=C2=A0 =C2=A0support.

=C2=A0 =C2=A0There are many different approaches to address Distributed Mob= ility
=C2=A0 =C2=A0Management, as for example extending network-based mobility pr= otocols
=C2=A0 =C2=A0(like Proxy Mobile IPv6), or client-based mobility protocols (= as
=C2=A0 =C2=A0Mobile IPv6), among others.=C2=A0 This document follows the fo= rmer
=C2=A0 =C2=A0approach, and proposes a solution based on Proxy Mobile IPv6 i= n which
=C2=A0 =C2=A0mobility sessions are anchored at the last IP hop router (call= ed
=C2=A0 =C2=A0mobility anchor and access router).=C2=A0 The mobility anchor = and access
=C2=A0 =C2=A0router is an enhanced access router which is also able to oper= ate as
=C2=A0 =C2=A0local mobility anchor or mobility access gateway, on a per pre= fix

=C2=A0 =C2=A0This document introduces the concept of distributed logical =C2=A0 =C2=A0interface, which is a software construct that allows to easily= hide

But, I=92d think the allocation of stable /64=92s is similar to static IPv4 (/32) address allocations that are supported in many operator networks today. There are also RADIUS / DIAMETER attributes such as Framed-IPv6-Prefix ..etc which can be used for obtaining statically configured values by PGW. So, IMO, its very much possible to allocate static IPv6 Per-UE prefixes for the UE. Its also possible to allocate static IPv6 prefixes for the networks behind UE. IMO, this is just a configuration and operators can surely do this today. But, I am not sure where we are going with this?
