Please excuse my delay for this clarifying comments. I have been
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:
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
A URL for the latter is:
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.

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,
