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. Plus it would be very nice to express
the Service Primitives in terms of 3GPP 5G reference points - for at
least a few of them. Otherwise there is a reasonable chance that people
from 3GPP and people from IETF may not see each others' points of view.
As I mentioned in an earlier email, I was somewhat surprised that
routing between access networks using heterogeneous physical media was
considered to be a problem, so the mismatch of viewpoints between the
SDOs really does seem to be a problem. I hope we can avoid it this next
time around! Maybe the FPC design for policy will be helpful. I could
imagine writing up a new section for inclusion in
draft-bogineni-dmm-optimized-mobile-user-plane, but as mentioned
elsewhere it is not clear just what are the criteria for selection. Or
(quite likely) I just missed it, but I'll try find it in the rush of
relevant emails after the last IETF.
Regards,
Charlie P.

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
