If your system is Huawei:

Call Drop Ratio on TCHF per cell (RM317)
Call Drop Ratio on TCHH per cell (RM327)

and how will we analyze the reason for the call drop

and how will we analyze the reason for the call drop

Check the Layer 3 message ..and check the measurement control messages ..try to analyze them carefully you will find the reason

Lapd call drops due to transmission link fluctuation
Handover failure call drops due to missing neighbor, need to PBGT margins, Frequency plan
Transcoder drops.
