Hi, Gunpowder!

Based on the methods of measuring neighboring cells, ANR is classified into event-triggered ANR and fast ANR (also known as periodic ANR).

Main function of event-triggered ANR is missing neighbor detection where UE performs cell measurements by default e.g. inter-frequency neighbor
cell measurement is triggered by A2 event.

Fast ANR is based on periodic measurement report, the UE may periodically measure and report the data in adjacent areas.
Fast ANR function occupies resources so normally this function has some limits: no more than a total of 20 UE,
or more than five times the same UE is elected to do periodic measurement report.
