It is definitely true that a handset with two different
radio interfaces, given proper infrastructure support and
software, can maintain excellent user experience as the
application session is maintained seamlessly while the handset
changes its care-of address to reflect its new point of
attachment to the Internet from a new radio interface.

Is this what you meant?

But the way in which authentication is carried out during
handovers has a crucial impact on the handover performance.
Do you not agree?
