RE: question on MIH event subscription



Hello Qiaobing,

In general I agree with your analysis below.
However we may just need to clarify what are MIH events.
All MIH events are listed in Table-4.

However consider the case of following primitive:
MIH_MN_HO_Candidate_Query.indication

It is an example of MIH_xxx.indication type of primitive, however I am
not sure if this is the case of an MIH event. As such MIH Users may not
need to subscribe for this.

Best Regards
-Vivek

The
