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.

PFD management method, network element and computer-readable storage medium

A traffic charging method, a network device and a storage medium are disclosed. The method may include: establishing a session with a session management function network element, and receiving a usage amount reporting rule transmitted by the session management function network element, the usage amount reporting rule comprising a first reporting mode field and a reporting threshold, the first reporting mode field comprising delayed reporting; and in response to a rate switching event occurring when the user plane function network element forwards a packet, continuously forwarding the packet until the reporting threshold is reached, and transmitting usage amount information to the session management function network element, so that the session management function network element transmits a call ticket to a charging function network element according to the usage amount information.

Traffic charging method, network device and storage medium

Provided are methods and related devices for implementing disaster recovery. According to a method, in a case where a main Session Management Function (SMF) fails, a backup SMF sends a first request to a User Plane Function (UPF), wherein the first request carries a node identifier (Node ID) of the main SMF, a Node ID of the backup SMF, and a Common Session endpoint Identifier List (CSIDLIST) corresponding to the backup SMF; and the first request is used for notifying the UPF that the main SMF fails and a session or sessions in the CSIDLIST corresponding to the backup SMF is/are to be taken over by the backup SMF, so that the UPF subsequently interacts with the backup SMF for the session or sessions in the CSIDLIST corresponding to the backup SMF.
