The present invention relates to a method for policy control in an infrastructure network. The network comprises a Policy Enforcement Function, PEF, an Access Function, AF, and a Policy Control Function, PCF, wherein the PEF comprises at least one pre-defined Policy and Charge Control, PCC, rule. The method comprises the steps of: —the PCF determines 23 the Quality of Service, QoS, properties and the identity of at least one pre-defined PCC rule in the PEF and provides said identity to the PEF, —the PCF assigns 24 the same identity to a QoS dynamic rule having the same QoS properties as said PCC rule and provides said dynamic rule to the AF, —the PEF determines 25 the identity of a pre-defined rule matching a user plane packet and encodes at least the identity in a user plane protocol between the PEF and the AF, —the AF identifies 26 the QoS dynamic rule provided by the PCF on the basis of the identity encoded in the user plane by the PEF, and controls the service data flow towards a user equipment on the basis of said QoS rule.
