H.323 Mobility Meeting November 17, 1999 8-10AM EST
Relevant files can be found here: ftp://standard.pictel.com/avc-site/Incoming/H.323_Mobility
Meeting Scope ------------- User, service, and terminal mobility (Annex H/H.323)
Liaisons -------- It was noted that the ITU-T SG16 will liaison with ITU-T SG11, ITU-R IMT-2000, ETSI TIPHON, as they are also addressing mobility. It was also suggested that we provide information to the IMTC (http://www.imtc.org) and 3GPP (http://www.3gpp.org/), although they are not a standards body, per se.
Report from Red Bank -------------------- MTD-02 reiterated what was discussed and agreed to in Red Bank. It was noted that TD-65 from Red Bank was an initial outline, but that was expanded and can be found in MTD-04a.
MTD-03 (Draft Annex H) ---------------------- This document contains the current draft text of H.323 Annex H. This document defines the ideas, functions, and entities of the H.323 mobile system. It also defines the requirements and architecture, though those sections are not fleshed out nor agreed to. People objected to the statement in the Scope section that stated "NPoA can change also during a call, thus allowing handovers", since we do not yet have an architecture defined. It was also suggested that we remove the references to IMT-2000, as it implies the H.323 mobile system will be compatible with IMT-2000. In reality, we want to borrow their ideas, but interworking will still be required between H.323 systems and IMT-2000 systems.
MTD-04 (Additional Items for Annex H Outlines) ---------------------------------------------- Several new sections to Annex H were proposed, including the areas of reliable transport of signaling, roaming interworking with non-H.323 networks, handover interworking with non-H.323 networks, non-H.323 supplementary services interworking, and mobile IP network interworking. However, only sections on roaming interworking with non-H.323 networks and non-H.323 supplementary services interworking were accepted as new sections in Annex H. Some issues were felt out of scope and others were felt as appropriate for Annex I/H.323.
Closing ------- It was agreed that future conferences will be hosted by the IMTC.
Since little progress was made during the conference call, more discussion needs to take place on the mailing list. Prior to the next call, we will narrow the number of documents we will discuss during the call.
The next call will be Monday, November 29, 1999 from 8-10AM PST.
