Hi all,

I have a problem about to calculation the Drop Call Rate (DPCR).

I use for calculation a Cell or a BSC this formula:

DPCR = DROP CALL RATIO = 100% * DPC / TCH NORM SEIZURES

But I found another formula for only Cells:

DPCR = DPCR_Cell = TCH DROP-OUT RATIO = 100% * DPC / (TCH NORM SEIZURES + TCH HO SEIZURES)

Which is rigt. I need your support.

regard´s
