Abstract
Methods, systems, and computer readable media for PCRF fault tolerance are disclosed. One exemplary method for PCRF fault tolerance includes sending, from the PCRF to a Diameter peer, a message concerning Diameter application session state information associated with Diameter application sessions currently or previously managed by the PCRF. The method further includes receiving, by the PCRF, a message from the Diameter peer in response to the message concerning the Diameter application session state information. The method further includes, determining, by the PCRF and based on the response, whether the Diameter application session state information maintained by the PCRF is accurate. The method further includes, in response to determining that the Diameter application session state information maintained by the PCRF is not accurate, requesting, by the PCRF, Diameter application session state information.
