This reminds me of philosophical discussions in mobility community about
network vs terminal controlled handover. The user (terminal) has the
ultimate power because they can always move to another operator.
However, it's a leap to say that therefore mobile-controlled handover is
the correct way of doing things (eg GSM took a different view & did
network controlled - I doubt if many users cared one way or the other!)
