RE: [802.21] question on MIH event subscription



Hi Qiaobing,

That is the cost of forgetting. :)

But seriously, this is (also) already supported that one MIH user may
set the thresholds with Link_Configure and another one can subscribes to
Link_Parameter_report. What is the issue here that leads you to think
inds are events? I think the confusion may be due to calling some events
indications. We should remove the term "indication" from the following.

MIH-Link-Parameters-Resport.indication
MIH-Link-Handover-Imminent.indication
MIH-Link-Handover-Complete.indication

Are there anymore?

Subject: [802.21] question on MIH event subscription

All,

I think the following statements should be true:

- any MIH .indication primitive shall be considered an MIH event
- an MIH User shall be notified about an MIH event only that User has
explicit subscription for the event

Therefore, we will need to accept the following scenario as perfectly
normal:

1. An MIH User invokes MIH_Configure_Link and sets some threshold in
order to get a link report when that threshold is crossed;

2. But he forgets to (or intentionally does not) explicitly subscribe
MIH_Link_Parameters_Report.indication event;

3. When the event happens, the User will not get the indication.

My reasoning is that one may want to build a User whose responsibility
is just to set link thresholds but the responsibility for receiving and
processing the events are delegated to a different User (or Users). The
latter will subscribe for the event but not the former.
