A1 and A2 event

Hi Experts,

What is the main purpose of A1 and A2 events?

Can we assume the following things …

A1 is for letting the EnodeB know that its not reqiured to configure any events as “serving is better than a configured thereshold”

A2 is for letting the EnodeB know that it is reqiured to configure A3 or A4 or A5 events as “serving is worse than a configured thereshold”

Triggering any event such as A3 or A4 or A5 is not possible without triggering A2 event.
