FIG. 2 shows a 5G architecture. Devices involved in the 5G architecture include: UE, a RAN, a User Plane Function (UPF) , a Data Network (DN) , an Access and Mobility Management Function (AMF) , an SMF, a PCF, an Application Function (AF) , an Authentication Server Function (AUSF) , and Unified Data Management (UDM) .

As shown in FIG. 2 , policy related network elements mainly include the PCF, the AMF, the SMF, the RAN, and the UE. The SMF is mainly responsible for executing session related policies. The AMF is mainly responsible for executing access and UE policy related policies.

Specific to a UE policy, information about the UE policy, including a content of the UE policy, an Identifier (ID) of the UE policy, etc., is monitored between the PCF and the UE through a container. In an uplink direction, the container is sent to the AMF by the UE through a Non Access Stratum (NAS) message, and continues to be transparently transmitted (without perception or modification) to the PCF by the AMF. Reversely, in a downlink direction, the container is sent to the AMF by the PCF, and is further transparently transmitted to the UE by the AMF through a NAS message.

One of the key Service Provider requirements for 5G/6G deployment is Energy Efficiency and lowering of Energy Cost. Up until 5G Rel-18, included, there was no consideration of energy efficiency as a parameter for making a 5GS policy decisions. There is ongoing standardization related to that, and, while considering Planned data transfer with QoS requirements policies by the PCF to be transferred to AF, it might be beneficial to consider energy related parameters and analytics in order to come up with a more efficient policies-related solution, energy utilization wise.

Planned Data transfer with Quality of Service (QoS) requirements (PDTQ) is widely covered in Rel-18 by the 3GPP TS 23.503 clause 6.1.2.7 and by the 3GPP TS 23.502 clause 4.16.15. As per TS 23.502, clause 4.16.15, the PDTQ policies are defined for a specific application service provider (ASP) and each PDTQ policy includes a recommended time window for the traffic transfer for each of the AF sessions involved.

The Network Performance analytics or DN Performance analytics for network data analytics function (NWDAF) as described in TS 23.288 will be subscribed by the PCF in order to assist its decision to derive the PDTQ policies.

One or more negotiated PDTQ policies could be provided by PCF to AF via NEF together with the PDTQ Reference ID. If the AF receives more than one PDTQ policies from the PCF, the AF will select one of them and inform the PCF about the selected PDTQ policy which will then be stored in the Unified Data Repository (UDR) . The selected PDTQ policy might be renegotiated, i.e. due to the degradation of the network performance. In this case, the PCF may determine a new list of candidate PDTQ policies and notify the AF via NEF. The AF may select one of the new PDTQ polices or not accept any of the PDTQ policies, it then notifies the PCF of the corresponding decision. Prior to the start of the selected time window for the planned data transfer, the AF requests the PCF to set up the AF session with required QoS. The PCF will then determine the appropriate Policy and Charging Control (PCC) rules according to the AF request. All the requirements and the flows may be referred at least to 3GPP TS 23.503 clause 6.1.2.7.

On top of that, and following the same principles as defined for Background Data Transfer (BDT) policy enhancements by the S2-2403191, this innovation proposes to enhance the negotiation for the PDTQ considering the energy related parameters and analytics in the following way:

The proposed solution enhances the existing PDTQ policy selection and re-negotiation process by introducing energy related information as service criteria. Specifically, it enhances the existing subscription and policy control framework to support energy consumption and energy efficiency service criteria.

The key aspects are enhancing set of information provided from the PCF to the AF (via NEF) with energy related parameters and analytics along with PDTQ policies, or, alternatively, taking energy related parameters and analytics when deciding on PDTQ policies so AF can take those into account while deciding on PDTQ policy selection. This can assist to AIML corresponding operation e.g. cost, operability and performance wise.

FIG. 3 is a flowchart of a method of PDTQ policy selection performed by PCF according to an embodiment of the present application. Referring to FIG. 3, the method 300 is performed by a network entity (e.g., Policy Control Function (PCF) ) and includes the followings. In Step 310, the network entity provides energy related parameters and analytics to Application Function (AF) along with one or more Planned Data transfer with Quality of Service (QoS) requirements (PDTQ) policies. That is, when providing the one or more PDTQ policies, the network entity also provides energy related information (i.e., the energy related parameters and analytics) to the AF for the AF to make PDTQ policy selection. The energy related information may include, but is not limited to, a target energy cost value, an energy identifier, a target energy efficiency value, and a charging rate, for example, for each of the PDTQ policies. In Step S320, the network entity is informed by the AF about one of the PDTQ policies, which is selected based on the provided energy related parameters and analytics. That is, the AF may select one of the PDTQ policies based on the energy related parameters and analytics provided by the network entity and informs the network entity of the selected PDTQ policy. The PDTQ policy selection is made in consideration of the energy related information. It is beneficial to consider energy related parameters and analytics in order to come up with a more efficient policies-related solution.

FIG. 4 is a flowchart of a method of PDTQ policy selection performed by PCF according to another embodiment of the present application. Referring to FIG. 4, the method 400 is performed by a network entity (e.g., Policy Control Function (PCF) ) and includes the followings. In Step 410, the network entity determines a set of Planned Data transfer with Quality of Service (QoS) requirements (PDTQ) policies based on energy related parameters and analytics. That is, the network entity can provide a set of PDTQ policies that are decided by taking energy related information (i.e., the energy related parameters and analytics) into account. The energy related information may include, but is not limited to, a target energy cost value, an energy identifier, a target energy efficiency value, and a charging rate, for example, for each of the PDTQ policies. In Step S420, the network entity provides the set of PDTQ policies to Application Function (AF) for the AF to select one from the set of PDTQ policies. That is, the AF may select one from the set of PDTQ policies determined in Step S410 and informs the network entity of the selected PDTQ policy. The selected PDTQ policy selection has already considered the energy related information. It is beneficial to consider energy related parameters and analytics in order to come up with a more efficient policies-related solution.

In some embodiments, the method further includes updating to the AF a list of new candidate PDTQ policies considering by itself energy criteria on new network conditions; and triggering re-negotiation to allow the AF to make PDTQ policy selection based on the new candidate PDTQ policies. This would help on dynamic PDTQ policy selection based on new network conditions.

In some embodiments, the method further includes informing the AF that energy criterion is not met; and being informed by the AF about a reselected PDTQ policy, which is reselected based on previously provided PDTQ policies. This would help on PDTQ policy reselection based on energy criterion.

FIG. 5 is a flowchart of a method of PDTQ policy selection performed by AF according to an embodiment of the present application. Referring to FIG. 5, the method 500 is performed by a network entity (e.g., Application Function (AF) ) and includes the followings. In Step 510, the network entity receives from Policy Control Function (PCF) energy related parameters and analytics and one or more Planned Data transfer with Quality of Service (QoS) requirements (PDTQ) policies. That is, when receiving the one or more PDTQ policies, the network entity also receives energy related information (i.e., the energy related parameters and analytics) from the PCF so as to make PDTQ policy selection based on the energy related information. The energy related information may include, but is not limited to, a target energy cost value, an energy identifier, a target energy efficiency value, and a charging rate, for example, for each of the PDTQ policies. In Step 520, the network entity selects one of the one or more PDTQ policies based on the received energy related parameters and analytics. In Step 530, the network entity informs the PCF about the selected PDTQ policy. That is, the network entity may select one of the PDTQ policies based on the energy related parameters and analytics provided by the PCT and inform the PCT of the selected PDTQ policy. The PDTQ policy selection is made in consideration of the energy related information. It is beneficial to consider energy related parameters and analytics in order to come up with a more efficient policies-related solution.

FIG. 6 is a flowchart of a method of PDTQ policy selection performed by AF according to another embodiment of the present application. Referring to FIG. 6, the method 600 is performed by a network entity (e.g., Application Function (AF) ) and includes the followings. In Step 610, the network entity receives from Policy Control Function (PCF) a set of Planned Data transfer with Quality of Service (QoS) requirements (PDTQ) policies which is determined based on energy related parameters and analytics. That is, the PCF can provide a set of PDTQ policies that are decided by taking energy related information (i.e., the energy related parameters and analytics) into account, and the network entity receives the set of PDTQ policies from the PCF. The energy related information may include, but is not limited to, a target energy cost value, an energy identifier, a target energy efficiency value, and a charging rate, for example, for each of the PDTQ policies. In Step 620, the network entity selects one from the set of PDTQ policies. In Step 630, the network entity informs the PCF about the selected PDTQ policy. That is, the network entity may select one from the set of PDTQ policies determined in Step S610 and informs the PCF of the selected PDTQ policy. The selected PDTQ policy selection has already considered the energy related information. It is beneficial to consider energy related parameters and analytics in order to come up with a more efficient policies-related solution.

In some embodiments, the method further includes receiving from the PCF an updated list of new candidate PDTQ policies considering energy criteria on new network conditions; and making PDTQ policy selection based on the new candidate PDTQ policies. This would help on dynamic PDTQ policy selection based on new network conditions.

In some embodiments, the method further includes being informed by the PCF that energy criterion is not met; and reselecting a PDTQ policy based on previously provided PDTQ policies. This would help on PDTQ policy reselection based on energy criterion.

The AF can also consider the target energy cost value, an energy identifier (i.e., to indicate the selection of a policy that minimizes the energy cost value) , a target energy efficiency value, the charging rate, and the other attributes of the PDTQ policies when deciding which PDTQ policy to select among those provided by the PCF (e.g., via NEF) . In other words, the AF can decide what trade-offs to make between energy cost value, monetary cost, the time window of the transfer, etc.

The PCF can also update a list of new candidate PDTQ policies considering by itself the energy criteria on the new network conditions, from which the AF can choose. It can also provide the reasons for triggering such re-negotiation to allow the AF to make a choice regarding the selection of the new PDTQ policy. Alternatively, the PCF can notify the AF indicating only that the energy criteria cannot be met, then the AF can select a different PDTQ policy.

Therefore, there are at least three possible solutions considering enhancing of PDTQ: (all PCF-AF communication can be done via NEF)

1. PCF providing the energy related parameters and analytics to AF along with PDTQ policies, so AF can decide.

2. PCF deciding on a set of PDTQ policies, while taking energy related parameters and analytics into account.

3. PCF informing AF that energy criteria can’ t be met, then AF would select a different PDTQ based on the set of PDTQ policies previously provided by PCF.
