Patent number: 12267179Abstract: A method of and a Session Management Function, SMF, for provisioning processing rules for user traffic at a User Plane Function, UPF, in a core network of a telecommunication network are disclosed. The core network comprises an Access and Mobility Management Function, AMF and a Policy Control Function, PCF. The SMF first transmits to the PCF a request for obtaining processing rules for user traffic; the SMF then receives from the PCF processing rules enabling at least one of a Uniform Resource Identifier, URI, level processing policy and a Server Name Indication, SNI, level processing policy for the user traffic and provision the received processing rules with the UPF. The UPF can then process user traffic based on the provisioned processing rules, differentiating the user traffic at the more detailed URI and/or SNI level.Type: GrantFiled: March 16, 2020Date of Patent: April 1, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Erik Wikström, Carlos Jimenez Cordon, Miguel Angel Muñoz De La Torre Alonso
