Yoshihiro Ohba,

Well it means you don't have to remember all the specific definitions of "layer 2 link", "layer 3 link" etc. I'm lazy - that's why I like generalised, clean architectures...

It depends what service you want to run over the link. When the link is capable of transferring the PDUs of the service running over it, then it's up. If you're saying there is no practical way for the UE to know whether such a link is up, then you've uncovered a problem with the protocol, not with the terminology.
But surely it's the L2 and L3 links that you want to handover, not the link between a UE and a MIH Information Server? I don't really understand the 802.21 terms, so I may well be mistaken...
