[0002] This application is based on and claims priority to Chinese Patent Application No. 202410946180.6, filed on July 15, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and more specifically, to an energy-saving method, apparatus, and device. Background Technology

[0004] In certain scenarios, such as when a terminal is located at the edge of a cell or in an area with weak signal coverage, in order to meet the terminal's normal communication or corresponding requirements (specific Quality of Service (QoS) requirements), the network needs to allocate more wireless resources to the terminal and increase the air interface transmission power. At the same time, the terminal also needs higher transmission power for air interface transmission. This behavior will increase the power consumption of both the network and the terminal. However, the terminal is not aware of this high power consumption on the network side, and may not be sensitive to its rapid power loss (or the user may not know that this is due to high power consumption communication at the cell edge). Therefore, the network equipment and the terminal may be in this high power consumption state for a long time, which does not meet the requirements of energy conservation and emission reduction and affects the user experience.

[0005] Therefore, how to reduce the energy consumption of network-side devices and terminals is a problem that needs to be solved. Summary of the Invention

[0124] Among them, network-side equipment 12 may include access network equipment or core network equipment.

[0125] Alternatively, access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit. Access network equipment may include base stations, wireless local area network (WLAN) access points (APs), or wireless Fidelity (WiFi) nodes, etc. Among them, base stations can be referred to as Node B (NB), Evolved Node B (eNB), Next Generation Node B (gNB), New Radio Node B (NR Node B), Access Point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B, Transmit / Receive Point (TRP), Non-Terrestrial Network (NTN) equipment (such as satellite or high altitude platform stations).

The term "base station" is not limited to specific technical terms. It should be noted that the embodiments of this application only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0126] Optionally, core network equipment may also be referred to as core network nodes, core network functions, or core network elements, and includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (or L-NEF), and Binding Support.

It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0128] To facilitate a better understanding of the embodiments of this application, the RAT or Frequency Selection Priority (RFSP) related to this application will be explained.

[0129] RFSPs are parameters on the radio side. They can be provided by the UDM as subscription data or by the PCF as part of the Access 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).

[0130] To facilitate a better understanding of the embodiments of this application, the energy consumption statistics and service adjustments related to the terminal granularity (per UE) of this application are explained.

[0131] The specific process for energy consumption statistics and service adjustments at the per-UE level can be summarized as follows:

[0132] 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.

[0133] 2) Data volume at the OAM reporting service level (e.g., network slicing).

[0134] 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.

[0135] 4) The billing function (CHF) or CN NF (such as SMF, NWDAF, EECF, etc.) performs energy consumption statistics and calculates the energy consumption value / energy value used by the UE.

[0136] EE.UE=(EE.Networkslice*DataVolume.UE) / (DataVolume.Networkslice); or,

[0137] EE.UE = Data Volume.UE * N;

[0138] 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.

[0139] 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.

[0140] To facilitate a better understanding of the embodiments of this application, the related access management (AM) policy, session management (SM) policy, or UE policy will be explained.

[0141] PCF can generate AM policy, SM policy or UE policy based on the energy consumption or energy efficiency information of EECF or NWDAF, as shown in Figure 2. Specifically, it can include the following steps 1 to 3.

[0142] Step 1. The EECF sends the collected energy consumption or energy efficiency information to the PCF, or the NWDAF sends the energy consumption or energy efficiency analysis information to the PCF.

[0143] a) Energy consumption or energy efficiency information includes the energy consumption or calculated energy efficiency generated by the terminal on the network side during communication. The granularity of energy consumption or energy efficiency can be at the UE level, the Protocol Data Unit (PDU) session level, or the QoS stream level.

[0144] b) When analyzing energy consumption or energy efficiency information, NWDAF analyzes the energy consumption or energy efficiency information of UE communication, such as results and performance, such as high energy consumption or low energy efficiency. The granularity of the analysis can be at the UE level, PDU session level, or QoS stream level.

[0145] Step 2. Upon receiving energy consumption / efficiency information or analysis data from the EECF or NWDAF, the PCF may optimize the AM policy, SM policy, or UE policy based on the received information, for energy-saving purposes. This might include updating the RFSP in the AM policy or reducing the QoS requirements in the SM policy.

[0146] Step 3. The PCF sends the generated Am policy to the AMF, the SM policy to the SMF, and the UE policy to the UE. The AMF performs access and mobility management based on the AM policy, such as sending the received RFSP to the base station for the base station to adjust the UE's RAT. The SMF reduces communication QoS based on the SM policy, etc.

[0147] It should be noted that, as shown in Figure 2, the updated RFSP information is determined based on energy consumption or energy efficiency data collected by the core network, or based on energy consumption or energy efficiency analysis information collected by the core network. The base station then adjusts the current UE's RAT (e.g., switching from 5G to 4G) according to the updated RFSP information. Compared to 5G, 4G network and terminal operation is simpler and consumes less power, thus achieving energy saving. Furthermore, as shown in Figure 2, adjusting NF (e.g., UPF) to adjust UE communication SM policies such as QoS parameters (e.g., lowering terminal QoS parameters), and adjusting AM policies (e.g., updating RFSP as mentioned above) can also achieve energy saving and emission reduction. However, these methods all involve direct network-side control for energy consumption optimization, without terminal participation. Direct network-side energy consumption optimization control can lead to a decline in the terminal's user experience, such as lowering communication QoS parameters.
