[H.323 Annex H Mobility] Clarification Request

[Nicolas Tran]

Hi Jaakko,
I took a little bit of time to go through the TD 2-129 "H.323 Annex Mobility",  and I have the following comments about  the section 6.2.2 "Visitor Location Function (VLF)"
   I am astonished to see that the Location Area is listed as one of the elements of the VLF database because it had been agreed while discussing the Alcatel contribution that the Location Area is NOT a concept to be handled by H323 mobility.
   although the whole text proposed by the Alcatel contribution has not been accepted, the principles of this contribution (that proposes the independance between the lower layer and H.323 Multimedia system) has been agreed .Hence the Visitor Location
   Function (VLF) section should not contain  elements such as TMSI, LMTI, MSRN corresponding to the radio concept.

Perhaps, would it be suitable, as requested to Alcatel for the registration section of his contribution, to provide message sequence charts explaining why the VLF should handle such TMSI, LMTI, MSRN entities.

Thanks a lot,
Nicolas.
