Hi, Everyone:

The document MD-106 (H.323 Annex H) submitted by the editor remains
basically same from the fundamentally point of view. So, the comments
provided on the September 8 email (copy enclosed) remains the same as stated
earlier. The comments can be summarized as follows:

The Annex should be divided into two parts:

Part 1: Within the scope of Q.13/16: Extension of H.323 (e.g., H.225.0 [RAS,
Q.931, Annex G] and H.245 messages): Terminals, GKs/BEs, GWs. (Contributions
are there: D.354 of SG16 Feb'00/TD-31 of Portland'00.)

Part 2: Outside the scope of Q.13/16: Back-end services related to Mobility
(or value-added services related mobility) containing VLF and HLF.

So, it can be seen clearly that MD-106 (H.323 Annex H) submitted by the
editor does not contain the basic part 1 which is within the scope of
Q.13/16 (it rather contains part 2 which is outside the scope of Q.13/16).

Hi, Everyone:

The draft does not contain the basic part: Extensions of H.323 (e.g.,
H.225.0 messages). Contributions are there (e.g., D.354 of SG16 Feb'00,
Geneva - reproduced as TD-31 in Portland [August 21-15, 2000]). GRQ messages
need to be removed to the base spec of H.323 because there is nothing
specific to be done with mobility. If it is used in the context of mobility,
the issues related to mobile need to be pointed out so that contributions
can be brought to address those issues. Contributions are there to note the
issues.

The another suggestion is to make two parts of the Annex: 1. Basic extension
of H.323 (H.225.0, H.245: Terminals, GKs/BEs, GWs) and 2. Back-end services
related to Mobility (or value-added services related mobility)containing VLF
and HLF.

Part 2 clearly does not have to be specific to H.323. It is a general
service related to mobility. Every application that needs mobility may like
to use these services. This will be addressed in the light of the all mobile
applications of all questions of all SGs of the ITU-T. So, it is
out-of-scope of Q.13/16 because Q.13/16 alone cannot makes this decision.

Please note that Security (AuF) is also needed for the fixed users. So, this
is a generic service that needs to be developed for both fixed and mobile
users. So, it also belongs to the base H.323 spec. That is, any
specification related to AuF should be moved to the base H.323 spec as well
because it belong to both and the standard should be developed accordingly.

For rapid determination, I would suggest to address part 1 only in the first
phase.

More specific technical comments will be given for each point once the
primary objectives are clarified.

Hi all,

I have uploaded MD-106 to URL:
ftp://standard.pictel.com/avc-site/Incoming/Mobility-AHG/Md-106_H323AnnexHDr
aft.zip .
The document is a cleaned up version of TD-42 of the Portland meeting  and
contains only editorial changes(as the template used in the draft document
so far was, for some reason, a total mess).
The only "exeption" to this is the following correction. Section 8.1 of
TD-42 included the text: "Reference points A and B are out of the scope of
this Annex.", which has been removed and instead section 8.3 now includes
the text: "Reference points B, C and D are out of the scope of this Annex
(Hinter is included but only as an option in case that utilization of
reference point A is not practical).".
The reason for this change is that the text in TD-42 is, as I understand
from Mr. Rissanen's comments, a typo and should have mentioned reference
points B and C instead of A and B.
