Counter Check Procedure is always initiated by eNB, by sending "Counter Check" message to UE.

When:

Whenever eNB finds the particular COUNT is exceeded than specific value.
Why:

UE will send Counter Check Response to eNB, by including drb-CountInfoList, drb-Identity, counte-Uplick, count-Downlink IE's corresponding to that specific COUNT value.
