Patent number: 11777861Abstract: 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.Type: GrantFiled: May 10, 2019Date of Patent: October 3, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Antonio Cañete Martinez, Miguel Angel Muñoz De La Torre Alonso, Jiehong Yang, Tianmei Liang
