Abstract
A PFD management method, a network element and a computer-readable storage medium are disclosed. The method may include: acquiring and storing PFD management request information sent by an Application Function (AF), wherein the PFD management request information comprises access point name (APN) information, application identifiers (APP ID), and a PFD, and the APN information and APP ID are associated with the PFD; and forwarding the APN information, the APP ID, and the PFD in the PFD management request information to a (user plane function) UPF through a Session Management Function (SMF), to cause the UPF to store the PFD according to the APN information and the APP ID.
Claims15
A method for managing Packet Flow Description (PFD), which is applied to a Network Exposure Element (NEF), the method comprising:
- acquiring and storing PFD management request information sent by an Application Function (AF), wherein the PFD management request information comprises access point name (APN) information, an application identifier (APP ID), and a PFD, and the APN information and APP ID are associated with the PFD, such that a User Plane Function (UPF) is allowed to identify the PFD according to the APN information;
- and
- forwarding the APN information, the APP ID, and the PFD in the PFD management request information to the UPE through a Session Management Function (SMF), to cause the UPF to store the PFD according to the APN information and the APP ID.
A method for managing Packet Flow Description (PFD), which is applied to a Session Management Function (SMF), the method comprising:
- acquiring access point name (APN) information, an Application Identifier (APP ID), and a PFD sent by a Network Exposure Function (NEF), wherein the APN information, APP ID, and the PFD are parameters associated with each other in PFD management request information, such that a User Plane Function (UPF) is allowed to identify the PFD according to the APN information, and the PFD management request information is acquired from an Application Function (AF) and stored by the NEF), and maintaining a cache duration of the PFD;
- and
- sending the APN information, the APP ID, and the PFD to the UPF, to cause the UPF to store the PFD according to the APN information and the APP ID.
A non-transitory computer-readable storage medium storing a computer-executable instruction which, when executed by a processor causes the processor to carry out a method for managing Packet Flow Description (PFD), which is applied to a Network Exposure Element (NEF), the method comprising:
- acquiring and storing PFD management request information sent by an Application Function (AF), wherein the PFD management request information comprises access point name (APN) information, application identifiers (APP ID), and a PFD, and the APN information and APP ID are associated with the PFD, such that the UPF is allowed to identify the PFD according to the APN information;
- and
- forwarding the APN information, the APP ID, and the PFD in the PFD management request information to a (user plane function) UPF through a Session Management Function (SMF), to cause the UPF to store the PFD according to the APN information and the APP ID;
- or, the computer program which, when executed by the processor causes the processor to carry out a method for managing Packet Flow Description (PFD), which is applied to a Session Management Function (SMF), the method comprising,
- acquiring access point name (APN) information, an Application Identifier (APP ID), and a PFD sent by a Network Exposure Function (NEF), wherein the APN information, APP ID, and the PFD are parameters associated with each other in PFD management request information, such that the UPF is allowed to identify the PFD according to the APN information, and the PFD management request information is acquired from an Application Function (AF) and stored by the NEF), and maintaining a cache duration of the PFD;
- and
- sending the APN information, the APP ID, and the PFD to a User Plane Function (UPF), to cause the UPF to store the PFD according to the APN information and the APP ID.
