RE: stds-802-16-mobile: Handoff document
Hi,
It is not simple to resolve the IP routing problem, in order to transfer
in the same time data to/from more than one BS. 3G, working with a circuit
switched solution, can do it in a relatively simple mode.
For me, "make before break" sounds better.

Itzik and HO-AH
I agree that the term Soft handover is not clear enough. It seems to me
that in Vladimir's C80216e-03/01, it means a soft transition, that is
with no break or failure of service, while hard HO requires a new NW
entry. I think we should distinguish betwee the mobility management
level and the data level. I understand the term soft handoff in the
data level, namely that the data is communicated between the MS and the
network via more than one base station. In that level there could be
more than one serving BS.

Dear Avi and all,
I agree with Avi.
I thought that "soft" and "hard" terms should be provided with relevant
context in order to prevent
misinterpretation of the terms.
The items 2.2.1 and 2.2.2 were a way to insert the "soft" and "hard" HO
as given by Vladimir Yanover in C80216e-03/01
without stating the explicitly "soft" and "hard" terms.
There was no explicit decision to exclude soft handoff, and I think that
considering soft handoff is relevant and should be made,
by providing with it the relevant context.

Dear Handoff ad-hoccers
I have been looking at the document Itzik had complied. I haven't seen
any mentioning of the possibility of soft handoff. Was there any
decision to exclude it? Soft handoff is not necessarily CDMA, you know,
and it might provide an advantage.
