Methods, systems, and computer readable media for implementing intelligent policy and charging rules function (PCRF) overload control
First Claim
1. A method for implementing intelligent Policy and Charging Rules Function (PCRF) overload control, the method comprising:
- at a Diameter Routing Agent (DRA) including at least one processor;
receiving an indication of a first overload level for at least a first PCRF of a plurality of PCRFs;
utilizing the indication of the first overload level received from the first PCRF to lookup a first routing rule stored locally on the DRA for routing message traffic to the first PCRF;
receiving message traffic requiring processing by the first PCRF; and
performing a first action specified by the first routing rule to accept the message traffic, reject the message traffic, or send a response on behalf of the first PCRF.

Abstract
The subject matter described herein includes methods, systems, and computer readable media for implementing intelligent PCRF overload control. A method may be performed at a Diameter Routing Agent (DRA) including at least one processor. The method includes receiving an indication of a first overload level for at least a first PCRF of a plurality of PCRFs and determining, from the first overload level, a first routing rule for routing message traffic to the first PCRF. The method further includes receiving message traffic requiring processing by the first PCRF and performing a first action specified by the first routing rule to accept the message traffic, reject the message traffic, or send a response on behalf of the first PCRF.

11. A system for implementing intelligent Policy and Charging Rules Function (PCRF) overload control, the system comprising:
-
a Diameter Routing Agent (DRA) including at least one processor, wherein the DRA is configured to receive an indication of a first overload level for at least a first PCRF of a plurality of PCRFs and to utilize the indication of the first overload level received from the first PCRF to lookup a first routing rule stored locally on the DRA for routing traffic to the first PCRF; a routing engine configured to receive message traffic requiring processing by the first PCRF and route the message traffic according to a first action specified by the first routing rule; wherein the DRA accepts the message traffic, rejects the message traffic, or sends a response on behalf of the first PCRF. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:
-
receiving an indication of a first overload level for at least a first PCRF of a plurality of PCRFs; utilizing the indication of the first overload level received from the first PCRF to lookup a first routing rule stored locally on the DRA for routing traffic to the first PCRF; receiving message traffic requiring processing by the first PCRF; and performing a first action specified by the first routing rule to either accept the message traffic or reject the message traffic on behalf of the first PCRF.
