5.51.2.2.3 Energy Consumption information collection from OAM
Taught in 27. Overload, energy, deployment and the rest (The 5G system architecture, in depth).
Table 5.51.2.2.3-1 provides the list of information received from OAM. EIF requests the energy consumption and data volume information per NF level from OAM by providing the serving gNB ID(s) and (I-)UPF ID(s) received from SMFs.
NOTE 1: The management consumer in EIF is configured with information to retrieve the energy related information from OAM as defined in TS 28.554 [209].
The node-level reporting interval from the OAM is the network-wide configurable starting time and interval T which is the same as data volume reporting interval from SMFs.
Table 5.51.2.2.3-1: Information from OAM for user-plane energy consumption calculation
| Information | Description |
|---|---|
| gNB energy consumption | The Energy consumed by a gNB over the configured time interval T based on clause 6.7.3.4.2 of TS 28.554 [209]. |
| gNB data volume | The UL/DL data volume handled by a gNB over the configured time interval T based on clause 6.7.1.1 of TS 28.554 [209]. |
| UPF energy consumption | The Energy consumed by a UPF over the configure time interval T based on clause 6.7.3.1 of TS 28.554 [209]. |
| UPF data volume | The UL/DL Data volume handled by a UPF over the configured time interval T. |
When the serving gNB and/or the (I-)UPF(s) of the UE are changed, the serving gNB ID and (I-)UPF ID(s) will be updated to the EIF through SMF(s). And then, the EIF requests the energy consumption and data volume information from OAM for the updated serving gNB ID and (I-)UPF ID(s).
NOTE 2: The Node-level Energy Consumption information and Node-level data volume information received from OAM could be used by EIF for all the UEs being served by the same NF or Node. If the EIF has subscriptions from one or more EIF Service Consumers for the same UE or different UEs, the Node-level information for one NF or Node is requested from OAM only once for all the subscriptions and it is used by the EIF for the calculations of the information required to provide the energy consumption information to these one or more EIF Service Consumer that subscribed to the EIF.
NOTE 3: In this Release, only the energy related information of user plane communication is supported and that of control plane signalling is not supported.
The EIF acts as the enforcement point for user consent for collection and processing of energy-related information depending on local regulations. For support of user consent (for collection and processing of energy-related information), the EIF communicates with the UDM as specified in Annex V of TS 33.501 [29].
