Event B1 is being used for Inter-RAT measurement report triggering event.
As per specification: Event B1 is used when Inter-RAT neighbor becomes better than the threshold. There are following inequality conditions are given which need to be fulfilled.

Entering Condition: Mn + Ofn - Hys > Thresh
Leaving Condition: Mn + Ofn + Hys < Thresh.

where "Mn" is measurement result of Inter-RAT neighbor cell and "Ofn" is frequency specific offset of the frequency of the inter-RAT neighbor cell. "Hys" is the hysteresis parameter for this event (i.e. Event B1)

Since both the events B1 and B2 are used for Inter RAT measurement reporting. Which one is chosen by eNodeB and on what basis ? Is there any dependency on UE capability for that ?
