KPI for EPC (Mandatory)



Accessibility KPI
EPS Attach Success Rate
This KPI describes the ratio of the number of successfully performed EPS attach procedures to the number of
attempted EPS attach procedures for EPC network and is used to evaluate accessibility provided by EPS and
network performance.
This KPI is obtained by successful EPS attach procedures divided by attempted EPS attach procedures
 


MM.EpsAttachAtt.Type
MM.EpsAttachSucc.Type
Note: above measurements with subcounter .Type should be defined in 3GPP TS 32.426 [2].
Dedicated EPS Bearer Creation Success Rate
 This KPI describes the ratio of the number of successfully performed dedicated EPS bearer creation procedures by PGW to the number of attempted dedicated EPS bearer creation procedures by PGW and is used to evaluate service availability provided by EPS and network performance.
This KPI is obtained by successful dedicated EPS bearer creation procedures divided by attempted dedicated EPS bearer creation procedures.
 
SM.CreationPGWInitBearerAtt
SM.CreatationPGWInitBearerSucc
(See in 3GPP TS 32.426 [2])
Dedicated Bearer Set-up Time by MME (Mean)
This KPI describes the valid time per dedicated bearer set-up procedure by MME and is used to evaluate service
accessibility provided by EPS and network performance.
This KPI is obtained by the valid time per dedicated bearer set-up procedure by MME
DBSTM= SM.EstabActDedicatedEpsBearerTimeMean (second)
SM.EstabActDedicatedEpsBearerTimeMean (See in 3GPP TS 32.426 [2]).
Service Request Success Rate
This KPI describes the ratio of the number of successfully performed service request procedures by UE to the
number of attempted service request procedures by UE and is used to evaluate service accessibility provided by
EPS and network performance.
This KPI is obtained by successful service request procedures divided by attempted service request procedures
 
SM.EpsServiceReqAtt
SM.EpsServiceReqSucc
(See in 3GPP TS 32.426 [2])
Mobility KPI
Inter-RAT Outgoing Handover Success Rate (EPS->GSM)
This KPI describes the ratio of the number of successfully performed outgoing handover procedures to the number of attempted outgoing handover procedures to evaluate inter RAT outgoing handover performance.
This KPI is obtained by the number of successful outgoing handover procedures divided by total number of
attempted outgoing handover procedures from EPS to GSM network.
 
 IRATHO.OutMMEAtt.G
IRATHO.OutMMESucc.G
(See in 3GPP TS 32.426 [2])
Inter-RAT Outgoing Handover Success Rate (EPS->UMTS)
This KPI describes the ratio of the number of successfully performed outgoing handover procedures to the number of attempted outgoing handover procedures to evaluate inter RAT outgoing handover performance.
This KPI is obtained by the number of successful outgoing handover procedures divided by total number of
attempted outgoing handover procedures from EPS to UMTS network.
 
 IRATHO.OutMMEAtt.U
IRATHO.OutMMESucc.U
(See in 3GPP TS 32.426 [2])
Inter-RAT Incoming Handover Success Rate (GSM->EPS)
This KPI describes the ratio of the number of successfully performed incoming handover procedures to the number of attempted incoming handover procedures to evaluate inter RAT incoming handover performance.
This KPI is obtained by total number of successful incoming handover procedures divided by total number of
attempted incoming handover procedures from GSM network to EPS
 

 IRATHO.IncMMEAtt.G
IRATHO.IncMMESucc.G
(See in 3GPP TS 32.426 [2])

Inter-RAT Incoming Handover Success Rate (UMTS ->EPS)
This KPI describes the ratio of the number of successfully performed incoming handover procedures to the number of attempted incoming handover procedures to evaluate inter RAT incoming handover performance.
This KPI is obtained by total number of successful incoming handover procedures divided by total number of
attempted incoming handover procedures from UMTS network to EPS
 
IRATHO.IncMMEAtt.U
IRATHO.IncMMESucc.U
(See in 3GPP TS 32.426 [2])
Tracking Area Update Success Rate
This KPI describes the ratio of the number of successfully performed tracking area update procedures to the
number of attempted tracking area update procedures and is used to evaluate mobility provided by EPS and
network performance.
This KPI is obtained by successful tracking area update procedures divided by attempted tracking area update
procedures.
MM.TauIntraSgwAtt
MM.TauInterSgwAtt
MM.TauIntraSgwSucc
MM.TauInterSgwSucc
(See in 3GPP TS 32.426 [2])
Utilization KPI
Mean Active Dedicated EPS Bearer Utilization
This KPI describes the ratio of the mean number of active dedicated EPS bearer to the maximum number of active dedicated EPS bearers provided by EPC network, and it is used to evaluate utilization performance of EPC network.
This KPI is obtained by the mean number of dedicated EPS bearers in active mode divided by the system capacity.
 

SM.MeanNbrActDedicatedBearer (See in 3GPP TS 32.426 [2])
Capacity indicates maximum number of active dedicated EPS bearers provided by EPC node.
Editor notes: Capacity definition is FFS.
