The embodiments herein relate to optimized procedure for Packet Flow Description (PFD) management. In one embodiment, there proposes a method () for managing Packet Flow Description (PFD), comprising: receiving (S) from a Session Management Function (SFM) () or a User Plane Function (UPF) () a demand message indicating the demand for at least one PFD rule for an application; detecting (S) the at least one PFD rule for the application; and notifying (S) information regarding the at least one PFD rule to the SMF () or the UPF (). The embodiments herein may achieve an optimized procedure for PFD Management which optimizes the delivery of PFD rules, by reducing the amount of signaling and by reducing the number of hops between the producer (AF) and the consumer (UPF).

Optimized procedure for PFD management

Periodic requests for to Packet Flow Description, PFD, data updates on all Application Ids generate a constant background load in several network function nodes, even if applications have not been updated. There is provided a mechanism to optimize PFD management updates in a telecommunication network, whereby PFD data for a selected number of applications are stored and updated permanently, whilst PFD data for other applications are only temporarily stored so that storage and updates are released when these other applications are not in use. A list of permanent Application Ids is configured for the most frequently used applications. When a control rule specifies an Application Id not included in the list of permanent Application Ids, the specified Application Id is included in a list of temporary Application Ids, which are periodically checked and, when not used, are removed from the list of temporary Application Ids.
