Without getting into the specifics of various definitions, I agree with
you that the aim of 802.21 is to facilitate the "existing" MM. Our
working principle should be based on undestanding of "current" IP
mobility mechanisms. Accordingly, IP address management is the job of IP
mobility mechanism. Anything related we do in 802.21 will not be in the
capacity of facilitating but will be in direct conflict with IP address
configuration/discovery mechanisms resulting in duplication and
confusion.

Because that is the founding principle to meanigfully define the scope
of work in 802.21. If there is no such signaling and if 802.21 were to
take over the job, we will define a new flavour of "FMIP or equivalent"
here in the WG.

I was very specific talking about whether or not "FMIPv6 or something
equivalent" is present in the upper layer. Now you changed the term to
"handover signaling"! And you seem to equal "handover signaling" to
"reduce[d] latency".
Any existing mobility management mechanism that I am aware of has
certain form of "handover signaling". Do you mean to say they already
achieved "reduce[d] latency"? Then why are we here to develop 802.21 to
facilitate the existing MM?

Please stay with "FMIPv6 or something equivalent" in this discussion. I
am still interested in hearing from you why it is not good if we assume
there is no "FMIPv6 or something equivalent" present in the upper layer?
