Abstract: 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.

Abstract: Methods and apparatus for managing quality of service for video streaming, in which a Policy and Charging Rules Function (PCRF) in a Policy Charging Control (PCC) architecture of a telecommunications system receives from a Policy Control Enforcement Function (PCEF) a notification indicating that a video service has started for streaming video content to a user equipment (UE).
