[0002] This disclosure claims priority to Chinese Patent Application No. 202410405684.7, filed in China on April 3, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of wireless communication, and more particularly to a data request method, network function, storage medium, and computer program product. Background Technology

[0004] Currently, in the core network, for a specific third-party application service on a terminal with special network requirements, pre-configuration through network management is the only option. This method is inflexible and inefficient. For services without specific configuration, default settings are used. However, for certain services, default settings may not be the most suitable configuration. For example, with the diversification, personalization, and significant differences in services offered by 5G-A and 6G technologies, the network mechanisms in these technologies struggle to meet service demands.

[0005] In the technical solutions of the Third Generation Partnership Project (3GPP), a Quality of Service (QoS) strategy is adopted to meet the service quality requirements of different users. The QoS strategy involves the Application Framework (AF) network function providing parameters, which are then distributed to the Unified Data Management (UDM) network function via the gateway system. During the Protocol Data Unit (PDU) session establishment, the Point Coordination Function (PCF) network function retrieves parameters from the UDM network function, declares the strategy, and distributes it to the Session Management Function (SMF) network function. The SMF network function then distributes it to the User Plane Function (UPF) network function for execution. However, this technology suffers from long strategy transmission paths and low transmission efficiency. Summary of the Invention

The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this disclosure.

[0078] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing embodiments of this disclosure only and is not intended to be limiting of this disclosure.

[0079] In the following description, references to "some embodiments" refer to a subset of all possible embodiments. It is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. It should also be noted that the terms "first, second, third" used in the embodiments of this disclosure are merely for distinguishing similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permissible, so that the embodiments of this disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0080] The current policy transmission path sequentially passes through AF network function, NEF network function, UDM network function, PCF network function, SMF network function, and UPF network function. See Figure 1 for details.

[0081] 1. Nnef_ServiceParameter_Create Request.

[0082] The AF network function sends an Nnef_ServiceParameter_Create Request to the Network Element Function (NEF) network function.

[0083] 2. Atuthorization.

[0084] The NEF network function, the Unified Data Repository (UDR) network function, and the UDM network function perform authorization operations.

[0085] 3. Storing information.

[0086] The NEF network function and the UDR network function store information.

[0087] 4. Nudr_DM_Notify.

[0088] The UDR network function sends Nudr_DM_Notify to the PCF network function.

[0089] Subsequently, PDU session establishment is performed between the PCF network function, UPF network function, SMF network function, the user's access and mobility management function (AMF) network function, the radio access network (RAN) network function, and the UE.

[0090] 5. SM Policy Association.

[0091] The PCF network function and the SMF network function perform a Session Management (SM) policy association operation.

[0092] 6. N4 session establishment.

[0093] N4 session establishment is performed between UPF and SMF.

[0094] The above-mentioned policy transmission method requires passing through multiple network functions, which leads to long policy transmission paths and low transmission efficiency.

[0095] To address the aforementioned problems, this disclosure proposes a data request method, as shown in FIG2, applied to a first network function. This method may include:

[0096] S101, Receive the creation request for the first service sent by the second network function.

[0097] In this embodiment of the disclosure, the creation request for the first service carries policy parameters.

[0098] In this embodiment of the disclosure, the first network function is the User Plane Function (UPF).

[0099] In this embodiment of the disclosure, the second network function is the Network Openness Function (NEF).

[0100] In this embodiment of the disclosure, the first service is a policy rule service.

[0101] In this embodiment of the disclosure, the method further includes at least one of the following: providing a first parameter to generate a policy rule; the first parameter may be a Quality of Service (QoS) parameter or a QoS policy; and feeding back the policy rule to a second network function.

[0102] In this embodiment of the disclosure, the first network function provides a first service.

[0103] In this embodiment of the disclosure, the first service is a service-oriented interface provided by the first network function.

[0104] In this embodiment of the disclosure, when the third network function subscribes to the first service, it inputs at least one of the following parameters: AF Identifier (AF ID), UE address, flow description information or external application identifier, QoS parameters, and the QoS parameters include at least one of the following: a packet filter set and a precedence value.

[0105] In this embodiment of the disclosure, the third network function is the application function AF.

[0106] In this embodiment of the disclosure, when the third network function subscribes to the first service, the input parameters are a specific set of parameters and / or a set of codes for an existing strategy.

[0107] It should be noted that a set of existing / specific parameters, such as the AF Identifier, UE address, Flow description information or External Application Identifier in QoS rules, and QoS parameters include: a Packet Filter Set, and the accuracy value.

[0108] It should be noted that an existing policy is coded as a precedence value in a QoS rule.

[0109] In this embodiment of the disclosure, a first service is added to the UPF network function, which is a service-oriented interface provided by the UPF network function; a second service is added to the NEF network function, which is a service-oriented interface provided by the NEF network function.

[0110] In this embodiment of the disclosure, a new Nupf_PolicyRule service (first service) is added to the UPF network function. The Nupf_PolicyRule is a service interface. The service operations that the Nupf_PolicyRule service can perform include Create, Update and Release. Its operation semantics are Request / Response. Its operation objects are the NEF network function and the AF network function.

[0111] In this embodiment of the disclosure, a new Nnef_PolicyRule service (second service) is added to the NEF network function. The Nnef_PolicyRule is a service interface. The service operations that the Nnef_PolicyRule service can perform include Create, Update and Release. Its operation semantics are Request / Response. Its operation objects are the UPF network function and the AF network function.

[0112] In this embodiment, the AF network function calls Nnef_PolicyRule Create Request (a second service creation request) to provide policy parameters to the NEF network function. The NEF network function authenticates the AF network function's request to determine whether the AF network function is qualified to directly input QoS policies. After authentication, the NEF network function calls Nupf_PolicyRule Create Request (a first service creation request) to request the UPF to report the QoS policy of a specific terminal. After receiving the policy, the UPF network function returns Nupf_PolicyRule_Create Response (a first service creation response) to the NEF network function, notifying whether the policy writing was successful.

[0113] In this embodiment, the policy parameters include identifiers for AF network functions, terminal addresses, process description information or external application identifiers, QoS parameters (packet filtering sets, priority values), etc. Specific selections can be made based on actual circumstances, and this embodiment does not impose specific limitations.

[0114] In this embodiment of the disclosure, the specific implementation process of providing policy parameters can be: providing a set of parameter values ​​to the NEF network function; or, providing preset parameter labels to the NEF network function, whereby the preset parameter labels represent a corresponding set of pre-configured parameter values. The specific choice can be made according to the actual situation, and this embodiment of the disclosure does not impose any specific limitations.

[0115] It should be noted that the set of parameter values ​​provided to the NEF network function can be a specific set of input parameter values, such as the identifier of the AF network function, terminal address, process description information, or external application identifier in the QoS rules, and the specific values ​​of QoS parameters (packet filtering set, priority value); or it can be a set of preset parameter labels of existing policies, such as the priority value in the QoS rules. The specific selection can be made according to the actual situation, and this disclosure does not impose specific limitations.

[0116] In this embodiment of the disclosure, the NEF network function sends an Nnef_PolicyRule Response (the creation response of the second service) to the AF network function to obtain the policy parameter writing result.

[0117] In this embodiment, after the NEF network function sends an Nnef_PolicyRule Response to the AF network function, the UPF network function sends an N4 session report to the SMF network function to report the policy update event. Upon receiving the report, the SMF network function replies with an N4 session acknowledgment message to the UPF network function. The SMF network function then calls Namf_Communication_N1N2Message Transfer to send the updated QoS profile to the AMF network function. Subsequently, the AMF network function forwards the updated QoS profile to the RAN network function via an N2 PDU session update message. Finally, the AMF network function returns an update response to the SMF network function via Namf_Communication_N1N2Message Transfer.

[0118] Understandably, the addition of the second and first services allows the AF network function to transmit policy parameters to the UPF network function via the NEF network function by calling the second and first services, thus shortening the policy transmission path and improving transmission efficiency.

[0119] Based on the above embodiments, if the AF network function has already gone through the authentication process of the NEF network function and has had policy input interaction with the UPF network function, when updating the policy parameters again, the AF network function can directly interact with the UPF network function without having to go through the forwarding of the NEF network function again. See Figure 3 for the specific process.

[0120] S102, the first network function receives an update request for the first service sent by the third network function, and the update request for the first service carries policy parameters.

[0121] In this embodiment of the disclosure, the third network function is the application function AF.

[0122] In this embodiment, the AF network function calls Nupf_PolicyRule_Update Request (the update request for the first service) to provide update policy parameters to the UPF network function. These parameters include the AF network function's identifier, terminal address, process description information or external application identifier, and QoS parameters (packet filtering set, priority value, etc.). The specific parameters can be selected according to actual circumstances, and this embodiment does not impose any specific limitations.

[0123] In this embodiment of the disclosure, after receiving the policy parameters, the UPF network function returns a Nupf_PolicyRule_Update Response (the update response of the first service) to the NEF network function to notify whether the policy writing was successful.

[0124] In this embodiment, after the UPF network function receives the policy parameters and returns a Nupf_PolicyRule_Update Response to the NEF network function, the UPF network function sends an N4 session report to the SMF network function to report the policy update event. Upon receiving the report, the SMF network function replies with an N4 session acknowledgment message to the UPF network function. The SMF network function then calls Namf_Communication_N1N2Message Transfer to send the updated QoS profile to the AMF network function. Subsequently, the AMF network function forwards the updated QoS profile to the RAN network function via an N2 PDU session update message. Finally, the AMF network function returns an update response to the SMF network function via Namf_Communication_N1N2Message Transfer.

[0125] Understandably, the addition of the first service allows the AF network function to directly transmit updated policy parameters to the UPF network function by calling the first service, thus shortening the policy transmission path and improving transmission efficiency.

[0131] In this embodiment of the disclosure, the second network function provides a second service.

[0132] In this embodiment of the disclosure, the second service is a service-oriented interface provided by the second network function.

[0133] In this embodiment of the disclosure, when the third network function subscribes to the first service, at least one of the following parameters is input: AF Identifier, UE address, Flow description information or External Application Identifier, and QoS parameters, which include at least one of the following: a Packet Filter Set and a precedence value.

[0134] In this embodiment of the disclosure, when the third network function subscribes to the first service, the input parameters are a specific set of parameters and / or a set of codes for an existing strategy.

[0135] Understandably, the addition of the second and first services allows the AF network function to transmit policy parameters to the UPF network function via the NEF network function by calling the second and first services, thus shortening the policy transmission path and improving transmission efficiency.

[0139] It should be noted that the first service is a policy rule service, and the second service is a policy rule service.

[0140] It should be noted that the second network function also receives policy rules sent by the first network function.
