Abstract
A system and method are described whereby interoperability is facilitated in a 3GPP network environment in combination with DIAMETER policy controls. Such interoperability enables updated policy rules to be fully communicated in on-line charging situations where quota expirations occur. This invention maintains centralized policy control in a 3GPP network with on-line charging.
Claims17
A system, comprising:
- a policy and charging enforcement function (PCEF) system;
- an on-line charging system (OCS) coupled to the PCEF system via a Gy interface;
- and
- a policy and charging rules function (PCRF) system coupled to said PCEF system via a Gx interface, wherein said PCRF system includes the ability to install in said PCEF system a filter that is configured to cause said PCEF system to contact said PCRF system upon an occurrence of an OCS event.
A method, comprising:
- installing a filter by a policy and charging rule function (PCRF) system into a policy and charging enforcement function (PCEF) system, wherein the filter is configured to cause the PCEF system to contact the PCRF system upon an occurrence of an OCS event.
A method, comprising:
- notifying an online charging system (OCS) by a policy and charging enforcement function (PCEF) system of a request for more quota;
- notifying the PCEF system by the OCS system of a quota breach;
- notifying a PCRF system by the PCEF system of the quota breach;
- and
- returning to the PCEF system by the PCRF system a policy decision.
A method, comprising:
- notifying an online charging system (OCS) by a policy and charging enforcement function (PCEF) system of a request for more quota;
- notifying the PCEF system by the OCS system of a quota breach;
- notifying a PCRF system by the OCS system of the quota breach;
- forwarding to the PCEF system by the PCRF system of a policy decision;
- and
- acknowledging to the PCRF system by the PCEF system of the policy decision.
A computer-readable medium containing instructions for controlling at least one processor by a method, comprising:
- notifying an online charging system (OCS) by a policy and charging enforcement function (PCEF) system of a request for more quota;
- notifying the PCEF system by the OCS system of a quota breach;
- notifying a PCRF system by the PCEF system of an expired quota;
- and
- returning to the PCEF system by the PCRF system a policy decision.
A computer-readable medium containing instructions for controlling at least one processor by a method, comprising:
- notifying an online charging system (OCS) by a policy and charging enforcement function (PCEF) system of a request for more quota;
- notifying the PCEF system by the OCS system of a quota breach;
- notifying a PCRF system by the OCS system of the quota breach;
- forwarding to the PCEF system by the PCRF system of a policy decision;
- and
- acknowledging to the PCRF system by the PCEF system of the policy decision.
