Accessibility Success Rate Definition
• KPI DEFINITION :
(Number of Call Established– Number of
Call Fails) / Number of Call Attempts
• FORMULA:
CSSR CS Voice (%) =
100*Sum(MOC_CONV_CALL_ATTS-
MOC_CONV_CALL_FAILS+MTC_CONV_CALL_ATTS-
MTC_CONV_CALL_FAILS+EMERGENCY_CALL_ATTS-
EMERGENCY_CALL_FAILS)/Sum(MOC_CONV_CALL_ATTS
+MTC_CONV_CALL_ATTS+EMERGENCY_CALL_ATTS-
RRC_ATT_REP_MO_CONV-RRC_ATT_REP_MT_CONV-
RRC_ATT_REP_EMERGENCY)*Sum(RAB_ACC_COMP_CS_
VOICE)/Sum(RAB_STP_ATT_CS_VOICE)
HSDPA Accessibility Success Rate (%) =
100*Sum(ALLO_HS_DSCH_FLOW_INT+ALLO_HS_DSCH_FL
OW_BGR)/Sum(ALLO_HS_DSCH_FLOW_INT+ALLO_HS_DS
CH_FLOW_BGR+REJ_HS_DSCH_RET_INT+REJ_HS_DSCH
