I think for purposes of Mobike, dormant mode could be defined as the mobile 
host will not be originating any packets for some period of time, including 
responses to IKEv2 probes, in order to preserve power but is still reachable 
at one of the addresses should any packets be incoming. Gratiutious packets 
should therefore be avoided.

No, I don't think "no active addresses" would properly characterize it. The 
host is still prepared to take incoming packets at one of the addresses its 
got (like for example an incoming phone call).

A deeper mode might be "no active addresses", in which the host either is 
turned off for the night, or isn't prepared to take any incoming packets, 
for even more power saving.

I think this behavior spans phones and laptops, the difference between the 
two is what happens to packets that come while the mobile host is in dormant 
mode. With laptops (802.11), the AP buffers them then delivers them when the 
laptop periodically wakes up and polls. With phones, the RNC gets on the 
paging channel and pages the mobile, then delivers the packets when the 
mobile wakes up and re-connects.
