Hi All,
I have a topic to open to discussion, I would like to know the effected of KPI "RRC Drop Rate"
Mostly of nominator is CCCH/DCCH.Unspec,
also want to know the way to solve this KPI.
As my exp. this cause can be come from
-improper drd setting.
-rnc release due to timer for ASU expried.
-Ue sent RAU to CN but have no feedback from CN with in time, then RNC will release RRC(cause :Unspecified).
Formula
100%*(RRC.AttConnRelCCCH.Cong+RRC.AttConnRelCCCH.Preempt+RRC.AttConnRelCCCH.ReEstRej+RRC.AttConnRelCCCH.Unspec+RRC.AttConnRelDCCH.Cong+RRC.AttConnRelDCCH.Preempt+RRC.AttConnRelDCCH.ReEstRej+RRC.AttConnRelDCCH.Unspec+VS.RRC.ConnRel.CellUpd)
