4 End to end KPI concept and overview p. 8
The following KPI categories are included in the present document:
- Accessibility (see the definition in [3]).
- Integrity (see the definition in [3]).
- Utilization.
- Retainability (see the definition in [3]).
- Mobility.
- Energy Efficiency.
- Reliability (See the definition in [13]).
- For future update of the document it will also include:

5 KPI definitions template p. 8
a)
Name (Mandatory): This field shall contain the name of the KPI.
b)
Description (Mandatory): This field shall contain the description of the KPI.
Within this field it should describe if the KPI is focusing on network or user view. This filed should also describe the logical KPI formula to derive the KPI. For example, a success rate KPI's logical formula is the number of successful events divided by all events. This field should also show the KPI unit (e.g., kbit/s, millisecond) and the KPI type (e.g., mean, ratio).
c)
Formula definition (Optional):
This field should contain the KPI formula using the 3GPP defined measurement names.
This field can be used only when the measurement(s) needed for the KPI formula are defined in 3GPP TS for performance measurements (TS 28.552). This field shall clarify how the aggregation shall be done, for the KPI object level(s) defined in d).
d)
KPI Object (Mandatory)
This field shall contain the DN of the object instance where the KPI is applicable, including the object where the measurement is made. The DN identifies one object instance of the following IOC:
e)
- NetworkSliceSubnet
- SubNetwork
- NetworkSlice
- NRCellDU
- NRCellCU
Remark (Optional):
This field is for additional information reqquired for the KPI definition,
e.g. the definition of a call in UTRAN.
