example 1
[0076] Example 1: Reference Figure 10 , Figure 10 The interaction process of querying PFD from NEF for SMF in PULL mode, the interaction process includes the following steps:
[0077] Step S1001, NEF receives PFD management request information sent by AF;
[0078] Step S1002, the NEF obtains the APN information, APP ID and PFD in the PFD management request information, and checks whether the AF is authorized according to the operator's policy;
[0079] Step S1003, the NEF sends the APN information, APP ID and PFD of the PFD management request information to the UDR;
[0080] In step S1004, the UDR determines the corresponding PFD list according to the APN information and the APP ID, and updates the PFD list according to the PFD.
[0081] Step S1005, UDR sends update confirmation information to NEF;
[0082] Step S1006, NEF sends PFD creation confirmation information to AF;
[0083] Step S1007, the SMF receives the PCF issued or activates a PCC rule including APN informa...

Abstract
The present invention provides a PFD management method, a network element and a computer readable storage medium, the PFD management method comprising: acquiring and storing PFD management request information sent by an AF, the PFD management request information comprising APN information, an APP ID and a PFD, the APN information, the APP ID and the PFD being associated; and forwarding the APN information, the APP ID and the PFD in the PFD management request information to a UPF through an SMF, so that the UPF stores the PFD according to the APN information and the APP ID. According to the scheme provided by the embodiment of the invention, the APN information can be added on the basis of the PFD and the APP ID, so that the UPF can distinguish the PFD according to the APN, mutual coverage among service data volume, application detection or charging control information is avoided, and the charging accuracy is improved.
Description
technical field [0001] The present invention relates to but not limited to the technical field of 5G communication, and in particular relates to a PFD management method, a network element and a computer-readable storage medium. Background technique [0002] In the fifth generation communication (5th Generation, 5G) system, the Network Exposure Function (NEF) is deployed with the Packet Flow Descriptions Function (PFDF), and the PFDF can obtain the Application Service Provider (Application Service Provider, ASP) or the packet flow description (Packet Flow Description, PFD) provided by the application function (Application Function, AF), and the session management function (Session Management Function, SMF) obtains the PFD and the application identifier (Application ID, After APP ID), it is issued to the corresponding User Plane Function (UPF), and UPF performs application detection according to the PFD, and implements the service according to the instructions in the policy an...
