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.
Claims21
A method, comprising:
- installing within a policy and charging enforcement function (PCEF) system an event filter, wherein the event filter is configured to indicate to the PCEF system to contact the PCRF system upon an OCS event;
- notifying, by the PCEF system via a Gy interface, an online charging system (OCS) of a request for more quota;
- receiving, by the PCEF system via the Gy interface, a notification of an OCS event from the OCS system;
- notifying, by the PCEF system via a Gx interface, the PCRF system of the OCS event;
- and
- receiving, by the PCEF system via the Gx interface, a policy decision from the PCRF system.
A method, comprising:
- notifying, by a policy and charging enforcement function (PCEF) system via a Gy interface, an online charging system (OCS) of a request for more quota;
- receiving, by the PCEF system via the Gy interface, a notification of an OCS event from the OCS system;
- notifying, by the PCEF system via a Gx interface, a PCRF (policy charging and rules function) system of the OCS event;
- receiving, by the PCEF system via the Gx interface, a policy decision from the PCRF system in response to the OCS event;
- and
- sending, by the PCEF system via the Gx interface, to the PCRF system an acknowledgement of the received policy decision.
A method, comprising:

- and
- returning, by the PCRF system via the Gx interface, to the PCEF system a policy decision.
