Hi, Folks:

I fully support what Roy is saying here. I assume that H.MMS.3 as well as H.MMS.2 will be based on H.MMS.1 protocol extensions. My understanding is that this 'new' H.MMS.1 protocol should be designed in a way that it is applicable not only to H.323 but to other applications protocols (e.g., H.234, H.310) as well. This will give more flexibility since it will not be specific to a particular application (i.e. no need of having a specific mobility management protocol for H.323, another one for H.324, etc.). Therefore, this 'new' protocol should be made independent as much as possible of others and not be called as H.225.0 annex G or its extension.

Please also see an earlier message sent by François Bougant which gives more clarification on these issues.

I appreciate this good start of Q5/16 work.

Best regards,

Jean-Claude Samou FTR&D

Hi, Manoj:

I am providing a very quick comment. It is a good proposal and you are assuming that H.MMS.1 will be the base protocol to be used.

With respect to H.MMS.1 protocol, I like to mention that the mobility management part of H.MMS.1 will be "called" a NEW protocol and will NOT be called as "H.225.0 Annex G or its extension."

Based on this assumption, probably you can start your work.

As time goes on, more comments will be provided.

I appreciate your work.

Best regards, Radhika R. Roy AT&T

Hi All, The purpose of this mail is to initiate work on H.MMS.3 standard, which is a part of H.MMS series for H.323 mobility systems. H.MMS.3 will address Presence and Instant Messaging services in H.323 Mobility multimedia systems. H.MMS.3 standard shall address the architecture, procedures and new message/ information elements to enable H.323 as the transport protocol for Presence and Instant Messaging in mobile environment. As editor of H.MMS.3 document, I solicit contributions and discussions to begin work in this area. Enclosed is the Scope and Terms of Reference document that was presented in SG16 Launceston meeting for H.MMS.3.

thanks Manoj Paul. Trillium Digital Systems, (an Intel company).
