6.1.1 Energy efficiency of NG-RAN |R17| p. 20
Assessment of NG-RAN data EE is based on the high-level mobile network data EE KPI defined in clause 3.1 and clause 5.3 of ETSI ES 203 228 [2]
NG-RAN data EE KPI is is obtained by the data volume divided by Energy Consumption (EC) of the considered network elements. The KPI is defined for both non-split and split gNB scenarios. This KPI is defined in clause 6.7.1 of TS 28.554.The following PEE (Power, Energy and Environmental) measurement may be used as the ECMN:
- PNF Energy consumption (cf. clause 5.1.1.19.3 of TS 28.552): This measurement provides the energy consumed (in kilowatt-hours) by the subject gNB.
6.1.2 Energy efficiency of network slices |R17| p. 20
6.1.2.1 Introduction p. 20
Assessment of the energy efficiency of 5G network slices is based on KPIs defined in clause 6.7.2 of TS 28.554.
The Generic network slice Energy Efficiency KPI is defined as the ratio between the performance of network slice to the Energy Consumption of the network slice. The KPI for Energy Consumption of the network slice is defined in clause 6.7.3.3 of TS 28.554.
The energy efficiency of 5G network slice is defined for each slice type as follows:
-
Energy efficiency of eMBB network slice, with the following variants:
- Energy efficiency of eMBB network slice, where the KPI is obtained by the sum of UL and DL data volumes at N3 interface(s) of the network slice, divided by the energy consumption of the network slice. This KPI is defined in clause 6.7.2.2 of TS 28.554.
- Energy efficiency of eMBB network slice - RAN-based, where the performance of the network slice is is obtained by summing up UL and DL data volumes at F1-U, Xn-U and X2-U interface(s) of gNBs, on a per S-NSSAI basis, divided by energy consumption of the RAN-only network slice. This KPI is defined in clause 6.7.2.2a of TS 28.554.
-
Energy efficiency of URLLC network slice, with the following variants:
- Energy efficiency of URLLC network slice based on latency of the network slice, where the KPI is obtained by the inverse of the average end-to-end User Plane (UP) latency of the network slice divided by the energy consumption of the network slice. This KPI is defined in clause 6.7.2.3.2 of TS 28.554.
- Based on both latency and data volume of the network slice, where the KPI is obtained by the product of the sum of the weighted UL and DL traffic data volumes at N3 interface(s) or N9 interface of the PSA UPF of the network slice multiplied by the inverse of the end-to-end User Plane (UP) latency of the network slice, divided by the energy consumption of the network slice. This KPI is defined in clause 6.7.2.3.3 of TS 28.554.
-
Energy efficiency of MIoT network slice, with the following variants:
- Based on the number of registered subscribers of the network slice, where the KPI is obtained by the maximum number of registered subscribers to the network slice divided by the energy consumption of the network slice. This KPI is defined in clause 6.7.2.4.1 of TS 28.554.
- Based on the number of active UEs in the network slice, where the KPI is obtained by the mean number of active UEs of the network slice divided by the energy consumption of the network slice. This KPI is defined in clause 6.7.2.4.2 of TS 28.554.
