The invention relates to an application function entity (100, 200, 300) configured to control policy rules of a packet based service data flow that is transmitted to a subscriber of a mobile communications network. The application function entity comprises a policy server (110) configured to control the policy rules of said packet based service data flow, the policy server containing a first interface (111) towards a traffic detection entity (140, 150, 65, 70) which detects the packet based service data flows in the mobile communications network. Furthermore, an interface (113) to a database is provided containing information with which policy rules to be applied to packet based service data flows can be determined. The policy server (110) is configured to determine, based on the information in the database (120), the policy for said packet based service data flow and configured to apply the policy rules to said packet based service data flow. |
