1. A method for policy control in an infrastructure network, comprising the steps of: determining Quality of Service (QoS) properties and an identity of at least one pre-defined Policy and Charge Control (PCC) rule; assigning a same identity to a QoS dynamic rule having the same QoS properties as said at least one PCC rule; determining an identity of a pre-defined rule matching a user plane packet and encoding at least the identity in a user plane protocol between a Policy Enforcement Function (PEF) and an Access Function (AF); and identifying the QoS dynamic rule on the basis of the identity encoded in the user plane, and controlling a service data flow towards a user equipment on the basis of said QoS dynamic rule.
