TCH Blocks in Negtive value

[Zaid Almajali]

can you please support to advice why could we have negative value sometimes for TCH Blocks or TCH Drops (-ve)

TCH Drop Rate % = TCH_AbNormal_Release / (TCH_AbNormal_Release + TCH_Normal_Release)

TCH_AbNormal_Release = DROP_AFTER_TCH_ASSIGN - TCH_RE_EST_ASSIGN
TCH_Normal_Release = TCH_NORM_RELEASE

please advice whom experiencing following issue

Dear Gents


2G drop rate KPI formula which considering TCH ReEstablishment.


TCH Drop Rate % = TCH_AbNormal_Release / (TCH_AbNormal_Release + TCH_Normal_Release)

TCH_AbNormal_Release = DROP_AFTER_TCH_ASSIGN - TCH_RE_EST_ASSIGN
TCH_Normal_Release = TCH_NORM_RELEASE

• Sometimes our 2G drop become negative because TCH_RE_EST_ASSIGN triggering more than DROP_AFTER_TCH_ASSIGN.
