Method for delivering dynamic policy rules to an end user, according on his/her account balance and service subscription level, in a telecommunication network

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.

Systems and methods are disclosed for performing Policy and Charging Control (PCC) for packet core networks. One embodiment comprises a PCC architecture that includes an online charging system (OCS). The OCS receives a request for charging rules for an initial data service from a PCRF. The request from the PCRF includes a service indicator for the initial data service. The OCS selects a charging method for the initial data service based on the service indicator, and transmits a response to the PCRF that includes the selected charging method. The PCRF may then make a PCC decision based on the charging method selected by the OCS, and a PCEF may enforce PCC rules for the initial data service. If there is a service changing during a data session, the OCS selects a charging method for the new data service, and the PCRF updates the PCC rules accordingly.
