  • Publication number: 20220191146
    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.

  • Patent number: 11356566
    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). A first Quality of Service (QoS) setting for streaming the video service to the UE is determined. First QoS setting data identifying the first QoS setting is transmitted to the PCEF. The PCEF transmits a further notification to the PCRF indicating that a particular stage has been reached. The PCRF receives the notification from the PCEF. In response to the further notification, a second QoS setting specifying a lower QoS than the first QoS setting for streaming the video service after the particular stage is determined. The PCRF identifies the second QoS setting to the PCEF.

  • Publication number: 20220086691
    Abstract: A network node for user data traffic handling (UPF), receives (52, 112) traffic for an application, wherein the traffic is to be sent to a logical server associated with the application, wherein the logical server resides on a network server (10.4), and wherein the application has a corresponding application function (AF). On detecting (53, 113) that the received traffic includes an encrypted server name indication such that the associated logical server cannot be identified, the network node requests (55, 115) from the corresponding application function information identifying the application. In response to receiving (62, 117) information identifying said application, the network node subsequently handles the traffic (63, 118) based on the identified application.

  • Patent number: 11171873
    Abstract: A method and a managing node for managing exchange of information relating to Packet Flow Descriptors, PFDs, between an application server and a network exposure node are disclosed. The managing node receives a message comprising a PFD with a PFD identifier, an external application identifier associated with the PFD, a server identifier of the application server, a transaction identifier, and a network exposure identifier identifying an operator network. The managing node stores received information. The managing node selects, based on the network exposure identifier, a network exposure node. When a PFD selection identifier is included in the message, the managing node selects, based on the PFD selection identifier, a further PFD amongst the set of stored PFDs. The managing node also determines an action for the further PFD. The managing node further transmits, towards the network exposure node, the PFD and an indication of the action.
