Not sure why NAS signaling Release Success Rate is multiplied in CS CSSR? Suggest to use the following formula: 100* sum([MOC_CONV_CALL_ATTS]-[MOC_CONV_CALL_FAILS]+ [MTC_CONV_CALL_ATTS] -

[MTC_CONV_CALL_FAILS] + [EMERGENCY_CALL_ATTS] - [EMERGENCY_CALL_FAILS] - [RRC_ACC_REL_EMERGENCY] - [RRC_ACC_REL_MO_CONV] - [RRC_ACC_REL_MT_CONV]) / 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] -[RRC_ACC_REL_EMERGENCY] -[RRC_ACC_REL_MO_CONV] -[RRC_ACC_REL_MT_CONV] -[RRC_CONN_STP_REJ_EMERG_CALL]) * sum([RAB_ACC_COMP_CS_VOICE]) / sum([RAB_STP_ATT_CS_VOICE] [RRC_ACT_REL_DIRECTED_RETRY)

The formula is actually used to calculate the PS Call Success Rate Suggest to revise the KPI name to PS Call Setup Success Rate (R99). Suggest to use the formula in next slide because some counters e.g.

RRC_ACC_REL_MT_HIGH_PR_SIGN are missing.
