The right way to do it may vary on the type of handover
under
consideration and the capabilities of the involved access
networks.
e.g. in some cases the access network may not be fully MIH
capable.

It's probably desirable not to limit the possible
deployment options
when developing the MIH solution except where constraints
are imposed by
things like security.

Thanks

And complexity  Supporting
all possible scenarios, theoretical and
practical, comes with a cost. We need to make a cost-benefit
analysis as we
go along.
