6.6.1 NG-RAN handover success rate

a) GRANHOSR.

b) A KPI that shows how often a handover within NR-RAN is successful, regardless if the handover was made due to bad coverage or any other reason. This KPI is obtained by successful handovers to the same or another gNB divided by attempted handovers to the same or another gNB. This KPI covers legacy Handover.

c)

d) SubNetwork, NRCellCU.

6.6.2 Mean Time of Inter-gNB handover Execution of Network Slice

a) InterGNBHOMeanTime.

b) This KPI describes the time of successful Mean Time of Inter-gNB handover which related to one single network slice and is used to evaluate utilization provided by the end-to-end network slice and network performance. This KPI is obtained by measuring the time between the receipt by the Source NG-RAN from the Target NG-RAN of a “Release Resource" and the sending of a " N2 Path Switch Request " message from Source NG-RAN to the Target NG-RAN over a granularity period. The unit of this KPI is millisecond.

d) Subnetwork

6.6.3 Successful rate of mobility registration updates of Single Network Slice

a) MobilityRegUpdateSR.

b) This KPI describes the successful rate of mobility registration updates in a network slice e at the AMF. This KPI is obtained by deviding the number of successful mobility registration updates at the AMFs by number of mobility registration update requests received by the AMFs of single network slice.

d) NetworkSlice

6.6.4 5GS to EPS handover success rate

a) 5GSEPSHOSR.

b) A KPI that shows how often a handover from 5GS to EPS is successful, regardless if the handover was made due to bad coverage or any other reason. This KPI is obtained by successful handovers from 5GS to EPS system divided by the total number of handovers attempt’s from 5GS to EPS system.

c)

d) SubNetwork, NRCellCU.

6.6.5 NG-RAN handover success rate for all handover types

a) GRANHOSRA.

b) A KPI that shows how often a handover within NR-RAN is successful, regardless if the handover was made due to bad coverage or any other reason. This KPI is obtained by successful handovers to the same or another gNB divided by attempted handovers to the same or another gNB. This KPI covers legacy Handover, Conditional Handover and DAPS Handover.

c)

d) SubNetwork, NRCellCU.
