Classification: CPC H | IPC H

Claim 19:
20. A method for delivering dynamic policy rules for an end user of a telecommunication system during a communication session, comprising:
providing a policy and charging rules function (PCRF) in the telecommunication system, wherein the PCRF is configured to communicate with a policy and charging enforcement function (PCEF) of the telecommunication system and an extended online charging system (EOCS) of the telecommunication system, wherein the PCEF sends a credit request to the EOCS for allocation of service units to a subscriber account associated with a communication session during the communication session, wherein the EOCS sends a credit answer with an allocation of service units for the subscriber account to the PCEF during the communication session in response to the credit request, wherein the PCEF monitors usage of the allocated service units during the communication session and sends a report on usage of the allocated service units to the EOCS during the communication session, wherein the EOCS determines a policy/rule change is needed for the subscriber account based at least in part on the report from the PCEF;
receiving a notification of policy change for the subscriber account from the EOCS at the PCRF during the communication session after the EOCS determines the policy/rule change is needed, wherein the notification of policy change for the subscriber account indicates the policy/rule change is needed; and
determining the policy/rule change for the subscriber account in response to the notification of policy change.
