[0095] To facilitate a better understanding of the embodiments of this application, the relevant terms are explained.

[0096] RAT, or Frequency Selection Priority (RFSP), is a parameter on the radio side. It can be provided by the UDM as subscription data or by the PCF as part of the Access and Management policy (am-policy). After the AMF obtains the RFSP index from the PCF, it is transparently transmitted to the gNB via an N2 message. Once transmitted to the gNB, the gNB can map this to its local configuration to form corresponding Radio Resource Management (RRM) policies. For example, the RFSP index is used to control the UE's camping in the cell or to determine whether the UE needs to be redirected to other frequency points or Radio Access Technology (RAT).

[0097] The NWDAF is responsible for processing and analyzing large amounts of data collected from various sources within the network. Based on the 3rd Generation Partnership Project (3GPP) specifications, the NWDAF is designed as an independent functional entity in the 5G core network architecture, interacting with other network functions through standardized interfaces.

[0098] NWDAF can interact with different entities:

[0099] Based on subscription events, NWDAF subscribes to events provided by AMF, SMF, PCF, UDM, and AF (directly or through NEF) to obtain data;

[0100] Retrieve information from a data repository, for example, retrieve information related to subscribers from a UDR via a UDM;

[0101] Retrieve information about network functions (NFs), for example, obtain information related to NFs through network repository functions (NRFs);

[0102] Provide analytical results to consumers based on their needs;

[0103] Provide bulk data to consumers;

[0104] Use the data collection and coordination function (DCCF) for analysis and data collection, including Operation Administration and Maintenance (OAM) data;

[0105] The NNF interface is used by NWDAF to request subscription to data delivery for a specific context, cancel subscription to data delivery, and request data reports for a specific context.

[0106] Each NWDAF is identified by an Analytics ID and a Region of Interest (ROI). A single NWDAF can provide multiple identities (IDs). The ROI is the geographic location to which the NWDAF belongs.

[0107] To facilitate a better understanding of the embodiments of this application, the energy consumption statistics and service adjustments at the terminal level related to this application are explained.

[0108] The specific process for energy consumption statistics and service adjustments at the per-UE level can be summarized as follows:

[0109] 1) OAM reports energy consumption data at the service (e.g., network slice) granularity and energy consumption data at the network element (e.g., NF) granularity.

[0110] 2) Data volume at the OAM reporting service level (e.g., network slicing).

[0111] 3) The core network (CN) (such as SMF or UPF) reuses the Quality of Service (QoS) monitoring mechanism to calculate the data volume of a single UE or a single UE for a single service.

[0112] 4) CHF or CNNF (e.g. SMF, NWDAF, EECF, etc.) performs energy consumption statistics to calculate the energy consumption / energy value used by the UE.

[0113] EE.UE=(EE.Networkslice*DataVolume.UE) / (DataVolume.Networkslice); or,

[0114] EE.UE = DataVolume.UE * N;

[0115] Where EE.UE represents the terminal's energy efficiency or energy consumption, EE.Networkslice represents the network slice's energy efficiency or energy consumption, DataVolume.UE represents the terminal's data volume, DataVolume.Networkslice represents the network slice's data volume, and N is a fixed coefficient, which is the average energy consumption consumed by the network for sending a unit of data packet.

[0116] 5) Based on the calculated UE-level energy consumption data, the network side performs relevant service operations or network optimizations to achieve network energy saving. For example, adjusting QoS parameters, and / or performing NF network function reselection, and / or UPF reselection.
