摘要

A method for delivering dynamic policy rules for an end user of a communication service during a communication session is provided. The method includes receiving subscription information at a Policy and Charging Rules Function (PCRF) in order to determine an initial policy; applying the initial rules via a Policy and Charging Enforcement Function (PCEF); triggering an Extended Online Charging System (EOCS) for the user's service/network resource usage; rating and charging the user via the EOCS in real time; triggering a change of policy in a change notification from the EOCS to the PCRF; determining new rules for the new policy at the PRCF; receiving the new rules and applying them at the PCEF.
