Hi folks,

I have just uploaded MD-105 to URL: ftp://standard.pictel.com/avc-site/Incoming/Mobility-AHG/Md-105_UsageOfH225A nnexG.zip .

The contribution includes a proposal for using the H.225 Annex G protocol in H.323 Annex H. A few comments about the contribution below: -Generally the H.225 Annex G protocol seems to fit to the needs of H.323 Annex H quite well. -Especially the procedures for locating the called User can easily be done by adopting the H.225 Annex G protocol. -Location updating procedures seem to be possible without any big changes to the protocol, but the authentication procedures probably require some additions and/or changes. -I have written the contribution with the assumption that the H.225 Annex G protocol can be used in interfaces: GK-VLF, VLF-HLF and HLF-AuF. This also includes the Inter-domain communications between VLFs and HLFs, although in some pictures I have used co-located BE/VLF and BE/HLF entities, just to show that at least this way the Inter-domain communications should be possible. -Also, after a bit of reconsideration, I think that we could leave the HLF-AuF interface out of the first version of the standard and assume that the AuF is always co-located with a HLF (at least from the point of view of the H.323 system). The interface is, however, described as using the H.225 Annex G protocol in this contribution.

I'm sure that you have questions and comments, so shoot!
