[0105] Electrical energy consumption is an important factor in the operating costs of Mobile Network Operators (MNOs) . In the future, the energy consumption and related carbon footprint may become an important regulatory criterion for the MNOs and Service Providers (SP) .
[0106] Climate change and increasing energy consumption are prompting mobile network operators to improve energy efficiency (EE) . Energy efficiency is a strategic priority for telecom operators around the world. In the future, the Energy usage for service (s) may be limited to some energy quota limit.
[0107] In the present application, a service can be identified by application identifier (s) , IP address information (IP Address (es) or Fully Qualified Domain Name (FQDN) , IP port) , Data Network Name (DNN) and Single Network Slice Selection Assistance Information (S-NSSAI) .
[0108] Some scenarios and requirements have been studied to improve energy efficiency and energy saving in the 5G system. The services can be delivered with diverse energy efficiencies and energy consumption policies. For example, the internet service provider X has an energy quota limit to deliver its service to customer. The energy consumption data can also be exposed to the service providers.
[0109] To achieve controlling the service delivery or policy based on the energy usage quota and energy consumption, or energy consumption data exposure, the key point is how to collect / determine the energy consumption that one or more Services have consumed in the 5G system.
[0110] The energy consumption data that one or more Services have consumed can be collected by OAM system only. The disadvantage of OAM mechanism is non real-time. The data collection via OAM often has hourly level delays. This patent proposes a method to collect the energy consumption data in real-time manner.
[0111] The FIG. 1 is a potential 5G architecture. For the sake of simplicity, less relevant network elements are not shown in the figure. In the following, some basic elements in the structure are introduced:
[0112] 1) A User Equipment (UE) is accessing 5G system (5GS) , obtains services via Next Generation Radio Access Network (NG-RAN) and interacts with an Access and Mobility Control Function (AMF) of the core network via the non-access stratum (NAS) signaling.
[0113] 2) NG-RAN (i.e. 5G Radio Access Network. ) is responsible for the air interface resource scheduling and air interface connection management of the network to which the UE is accessed to.
[0114] 3) Access and Mobility Management function (AMF) includes the following functionalities: registration management, connection management, reachability management and mobility management. This function also performs the access authentication and access authorization.
[0115] 4) Session Management Function (SMF) includes the following functionalities: session management e.g. session establishment, modify and release, UE IP address allocation &management, selection and control of UP function and downlink data notification, etc.
[0116] 5) User Plane Function (UPF) includes the following functionalities: anchor point for Intra- / Inter-RAT mobility, packet routing &forwarding, traffic usage reporting, Quality of Service (QoS) handling for user plane, downlink packet buffering and downlink data notification triggering, etc.
[0117] 6) Unified Data Management (UDM) manages the subscription profile for the UEs. The subscription includes the data used for mobility management, session management. The AMF and SMF get the subscription from the UDM.
[0118] 7) Policy Control Function (PCF) includes the following functionality: supporting unified policy framework to govern network behavior, providing policy rules to Control Plane function (s) to enforce the policy rule.
[0119] 8) Network Exposure Function (NEF) is deployed for exchanging information between 5G core network (5GC) and the external third party.
[0120] 9) Application Function / Application Server (AF / AS) provides the service over 5G system.
[0121] 10) Unified Data Repository (UDR) supports the following functionality: storage and retrieval of subscription data by the UDM, storage and retrieval of policy data by the PCF, storage and retrieval of structured data for exposure.
[0122] 11) Network Repository Function (NRF) supports network function (NF) instance profiles registration and service discovery. It can receive NF Discovery Request from Consumer NF and provide the information of the discovered NF instances to the Consumer NF.
[0123] 12) Network Data Analytics Function (NWDAF) supports data collection from NF / AF / OAM and information retrieval from data repositories (e.g. UDR) . The NWDAF supports Machine Learning (ML) model training, information analytics and can provide the analytics data to NF and AF.
[0124] 13) Energy Efficiency and Consumption Function (EECF) collects energy related information in the 5G system, including: energy consumption related information, energy efficiency related information, renewable energy and carbon emission related information. The EECF can determine / calculate and store the energy usage status and exposure the energy information to the authorized consumers.
[0125] The Energy Efficiency and Consumption Function (EECF) can be standalone NF, or all or part of ECEF can be part of other 5G network functions, e.g. NWDAF, PCF, UDR or NEF. When EECF is part of other 5G network function, e.g. NWDAF, PCF, UDR or NEF, the EECF can literally be replaced by other 5G network functions. For example, if the ECEF is part of NWDAF, ECEF can literally be replaced by NWDAF in the procedure, and the interaction between EECF and NWDAF is internal behavior in the NWDAF.
[0126] In some embodiments the EECF functionality and related procedure have not been decided.
[0127] The present patent application provides a method to dynamically collect the energy consumption data for one or more Services in a real-time manner.
[0128] In this application, the energy related data includes Energy Consumption (EC) data and Energy Efficiency (EE) data. The energy usage or energy consumption (EC) refers to the same concept. The EC can be expressed in Joule (J) or Watthour (Wh) . The energy efficiency (EE) data can be expressed in Data Volume (DV) divided by Energy Consumption (EC) . The EE and EC data can be service level in the present application.
[0129] In the present application, the EECF collects the energy related data from UPF and / or OAM and / or NWDAF (e.g. for NG-RAN and other NF energy related data) and calculates the whole energy consumption for one or more service.
[0130] Specifically, the UPF may register the service information to NRF. The EECF discovers the UPF evolving in the services. EECF requests / subscribes evolved UPF to report the energy consumption related information for one or more services. The UPF measures the energy consumption related information for one or more services, and reports to EECF. EECF may derive the energy consumption data for one or more services according to UPF report.
[0131] Alternatively, EECF subscribes to OAM for energy consumption related data (Energy consumption and Energy efficiency data) for involved slice and / or UPF and determines the energy consumption data for one or more services according to UPF and OAM report / response.
[0132] Alternatively, the EECF subscribes / requests to NWDAF for calculating energy consumption data.
[0133] Embodiment I
[0134] Referring to FIG. 2, a first embodiment of the present disclosure is illustrated.
[0135] Specifically, according to the first embodiment, the present application discloses how the EECF obtains the UPF profiles for one or more services.
[0136] S201: The EECF subscribes to NRF for the NF status, i.e. UPF information. The subscription condition may include NF type (i.e. UPF) , slice information (i.e. S-NSSAI) , DNAI (Data Network Access Identifier) , service (s) information. The service information may include application identifier (s) , IP address information (IP Address (es) or FQDN (s) , IP port) , or DNN and S-NSSAI.
[0137] S202: The UPF registers its profile to the NRF. When the profile information is changed, the registration to NRF can be updated. The profile may include the S-NSSAI (s) and Service (s) information it is serving. The service (s) information may include application identifier (s) , IP address information (IP Address (es) or FQDN (s) , IP port) , or DNN and S-NSSAI.
[0138] S203: When the NRF determines the profile of NFs (i.e. UPF) meet the EECF subscription condition in the step S201, it sends the UPF information to the EECF.
[0139] In the present application, there is no certain step sequence requirement between step 201 and 202. Steps 201 and 202 can be implemented with any sequences.
[0140] Embodiment II
[0141] Referring to FIG. 3, a second embodiment of the present disclosure is illustrated. In this embodiment, application function (AF) or 5G NF can request the energy consumption data for one or more services. The EECF collects the energy consumption related data from UPF and determines the energy consumption data for one or more services.
[0142] Specifically, according to this embodiment, the present application discloses that how the EECF collects the Energy consumption related data and determines the energy consumption data for one or more services.
[0143] Some of the steps S303 is same with step S201 in the FIG. 2.
[0144] S301: The AF requests / subscribes to NEF for energy consumption data for one or more services. A service can be identified by application identifier (s) , IP address information (IP Address (es) or FQDN (s) , IP port) , or DNN and S-NSSAI. This request also contains the time condition (start time and / or end time) , report condition (periodic reporting, threshold reporting) . This request / subscription may also contain renewable energy indication and / or carbon emission information indication.
[0145] The renewable energy indication indicates that how much of the energy consumed is renewable energy. The carbon emission information indication indicates the carbon emission information during the energy consumption.
[0146] If AF is in the trusted domain, the NEF is not needed in this figure. The AF can send the request / subscription to the EECF directly, i.e. step S302, and EECF can report to AF directly, i.e. step S309.
[0147] S302: The NEF authorizes the AF request. If there is no slice information (i.e. S-NSSAI) in the request, the NEF maps the application information to slice information (S-NSSAI) or DNAI.
[0148] The NEF subscribes / requests to EECF for energy consumption data for one or more services. The information in the request received in the step S301 is included. If there is no slice information (i.e. S-NSSAI) in the step S301, the mapped slice information (S-NSSAI) or DNAI is also included. The 5G NF may also subscribe / request to EECF for energy consumption data for one or more services with this step.
[0149] S303: This step is the same with step S201. The EECF subscribes to NRF about the UPF information. The subscription condition may include NF type (i.e. UPF) , slice information (i.e. S-NSSAI) , DNAI (Data Network Access Identifier) and service (s) information.
[0150] S304: This step is the same with step S203. NRF sends the UPF information to the EECF.
[0151] S305: The EECF requests / subscribes UPF to report the energy consumption information for one or more services with the time condition and report condition information received in the step S302. This request / subscription message may comprise the Nupf_EventExposure_Subscribe service operation. A service can be identified by application identifier (s) , IP address information (IP Address (es) or FQDN (s) , IP port) , or DNN and S-NSSAI. There may be an indication in this message indicating that this is for the energy consumption information.
[0152] S306: The UPF measures the energy consumption related information for one or more services, and reports to EECF when the report condition and / or time condition is met. The report may include any of the following: data volume (UL, DL, and / or overall) of the service, data volume (UL, DL, and / or overall) of the service in each slice, energy consumption data (UL, DL, and / or overall) of the service in UPF, energy consumption data (UL, DL, and / or overall) of the service in each slice in UPF.
[0153] For example, the UPF supports 5 slices, and the one or more services are carried on the slice-1 and slice-2. The UPF reports (slice-1, data volume in slice-1, energy consumption data in slice-1) and (slice-2, data volume in slice-2, energy consumption data in slice-2) .
[0154] S307: The EECF receives the UPF energy consumption information. It then determines the energy consumption data for one or more services.
[0155] The EECF may derive the energy consumption data for one or more services based on preconfigured formulas, e.g. the overall energy consumption is X times of the UPF energy consumption.
[0156] The EECF may further interact with other 5G entity / NF for determining the energy consumption data in the FIG. 4 and 5 (Embodiment III and IV) .
[0157] S308: When the report condition (periodic reporting, threshold reporting) is met, EECF reports the energy consumption data for one or more services to NEF or 5G NF. This energy consumption data may contain the renewable energy consumption data and carbon emission information in the whole energy consumption data.
[0158] S309: NEF reports the energy consumption data to AF.
[0159] Embodiment III
[0160] Referring to FIG. 4, a third embodiment of the present disclosure is illustrated. The EECF can further collect the energy consumption information from OAM to determine the energy consumption data for one or more services.
[0161] Specifically, according to another embodiment, the present application discloses how the EECF further collects the energy consumption information from OAM to determine the energy consumption data for one or more services.
[0162] The step S402 is implemented after step S306 in the FIG. 3.
[0163] S401: The OAM system has obtained the energy consumption related data (energy consumption and energy efficiency data) from RAN node and 5G NF (including control plane and user plane NF) .
[0164] S402: The EECF receives the energy consumption related data for one or more services from UPF in the step S306 in the FIG. 3.
[0165] S403: The EECF subscribes / requests to OAM for energy consumption related data (energy consumption and energy efficiency data) . The EECF may request network slice (s) and / or network function energy consumption related data from OAM.
[0166] The EECF determines that the one or more services are carried in several slices according to the embodiment I and II. For example, according to the UPF (s) report, the EECF can determine which slice (s) are carrying these services. Then the EECF can request the OAM to report the related slice (s) energy consumption related data.
[0167] The EECF determines that the one or more services are carried in several UPFs according to the embodiment II. Then the EECF can request the OAM to report the related UPF (s) energy consumption related data.
[0168] S404: The OAM responds to / notifies the EECF with energy consumption related data. The energy consumption related data may contain any of the following: the slice (s) (received in the step S403) energy consumption data and data volume of the related slice, energy efficiency data of slice (s) (received in the step S403) ; the UPF (s) (received in the step S403) energy consumption data and data volume of the related UPF and energy efficiency data of UPF (s) (received in the step S403) .
[0169] S405: The EECF determines the energy consumption data for one or more services.
[0170] For example, the energy consumption data for the one or more services can be calculated as sum of the energy consumption of the services in each slice that hosts the services. The energy consumption of services in each slice is equal to the data volume (DV) of the services in the slice divided by the data volume (DV) of the slice multiplied by the energy consumption (EC) of the slice.
[0171] If the OAM system responds with UPF energy consumption related data instead of slice energy consumption related data, EECF calculates the sum of energy consumption of one or more services in the each UPF that forwards the services packet, and further derives the energy consumption data in the 5G system using the similar method in the step S307. The energy consumption of services in each UPF is equal to the data volume (DV) of the services in the UPF divided by the data volume (DV) in the UPF multiplied by the energy consumption (EC) of the UPF.
[0172] Embodiment IV
[0173] Referring to FIG. 5, a fourth embodiment of the present disclosure is illustrated. The EECF can determine the energy consumption data for one or more services based on energy consumption information from NWDAF, or with the NWDAF assistance.
[0174] Specifically, according to another embodiment, the present application discloses how the EECF further determines the energy consumption data for one or more services with the assistance from NWDAF.
[0175] The step S502 is implemented after step S306 in the FIG. 3 and / or step S404 in the FIG. 4.

[0179] - The EECF may request energy consumption related data for one or more services in the RAN nodes, or
[0180] - The EECF may send the energy consumption related data received in the step S306 and related UPF information to NWDAF, and request the NWDAF to determine the energy consumption data for one or more services.

[0182] - The NWDAF may respond with the energy consumption related data for one or more services in the RAN nodes, or
[0183] - The NWDAF may respond with energy consumption data for one or more services according to EECF request.
[0184] S505: The EECF determines the energy consumption data for one or more services.
