1. A method of supporting Packet Flow Descriptor (PFD) management implemented by an Application Function (AF) in a Service Based Architecture (SBA) based telecommunication network, the method comprising:
transmitting to a Network Exposure Function (NEF) in the telecommunications network, an on-board request message comprising an indication of supporting a PFD management service and comprising a list of application identifications and classification types that are supported by the PFD management service for obtaining PFDs;
receiving, from the NEF, a request message for requesting a PFD, the request message comprising an application identification for identifying an application, the request message corresponding to a PFD pull procedure triggered by a Session Management Function (SMF), the PFD pull procedure including a query of a Unified Data Repository (UDR) for the PFD for the application identification enabling the SMF to identify that the requested PFD for the application identification is available; and
transmitting, to the NEF, a response message comprising the application identification and the requested PFD.
