METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA DIVERTING DIAMETER TRAFFIC FROM AN OVERLOADED POLICY AND CHARGING RULES FUNCTION (PCRF)

摘要

The subject matter described herein includes methods, systems, and computer readable media for implementing intelligent routing via diverting Diameter traffic from an overloaded Policy and Rules Charging Function (PCRF). An exemplary method includes receiving, at a Diameter Routing Agent (DRA), a first session establishment request for a subscriber and generating a routing entry in a routing table that associates the subscriber with a first destination identifier identifying a first PCRF. The method also includes receiving an indication that the first PCRF is overloaded, receiving a second session establishment request for the subscriber, and generating a new routing entry in the routing table that associates the subscriber with a second destination identifier that does not identify the first PCRF.

1. A method for implementing intelligent routing via diverting Diameter traffic from an overloaded Policy and Charging Rules Function (PCRF), the method comprising:
at a Diameter Routing Agent (DRA):
receiving, at the DRA, a first session establishment request for establishing a first policy session for a first packet data network (PDN) connection involving a subscriber;generating, at the DRA, a routing entry in a routing table that associates the first PDN connection involving the subscriber with a first destination identifier identifying a first PCRF;receiving, at the DRA, an indication that the first PCRF is overloaded;receiving, at the DRA, a second session establishment request for establishing a second PDN connection involving the subscriber; andgenerating, at the DRA, a new routing entry in the routing table that associates the second PDN connection involving the subscriber with a second destination identifier that does not identify the first PCRF thereby diverting traffic away from the first PCRF.
