Claim 14:
15. A policy and charging rules function (PCRF) for a telecommunication system to facilitate dynamic management of policy rules for an end user of the telecommunication system during a communication session, the PCRF comprising:
at least one processor and at least one memory including computer program code;
at least one first communication interface configured for communications between the PCRF and an extended online charging system (EOCS) of the telecommunication system; and
at least one second communication interface configured for communications between the PCRF and a policy and charging enforcement function (PCEF) 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 PCEF receives a credit answer from the EOCS with an allocation of service units for the subscriber account during the communication session;
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 report from the PCEF is to be used by the EOCS to determine a policy/rule change is needed for the subscriber account;
wherein the at least one processor, the at least one memory, the computer program code, and the at least one first communication interface are configured to receive a notification of policy change for the subscriber account from the EOCS during the communication session, wherein the notification of policy change for the subscriber account indicates the policy/rule change is needed;
