Re: [802.21] [DNA] Prefix information for link identification in DNA
Stefano,
Sorry for late reply. Still catching up my email after a vacation.

Since the MIH users of this event are at IP layer and above, they would not have use of an indication stating that the UE has setup a L2 connection with a BSS or SGSN (since that is only signalling, not user plane). Link up in this case means that the UE has a usable PDP context with a GGSN and therefore has been assigned and IP address, so that the link can be used to carry data.

So, your "link_up" here means the IP connectivity is up and ready. In
other words, your "link" here refers to the IP link used in DNA, instead
of a L2 link. Do you think in general 802.21 link events should be
defined for IP link?
