Abstract: A policy and charging rules function (PCRF), generates a Diameter audit message concerning an application level Diameter session for which local resources are maintained by the PCRF. The PCRF includes, in the audit message, a fake parameter value. The PCRF sends the audit message with the fake parameter value to the OCS or the AF over an Sy or Rx interface. The PCRF receives a response to the audit message from the OCS or AF. The PCRF determines, based on the response, whether the application level session comprises and orphan session. The PCRF, in response to determining that the application level Diameter session comprises an orphan session frees the local resources maintained by the PCRF for the orphan session.

Abstract: Systems, methods, and computer readable media for detecting and mitigating address spoofing in messaging service transactions are disclosed. A messaging service firewall (MSF) separate from a short message service center (SMSC) receives a mobility management reply message (MMR) that is sent by a mobile location register element in response to an associated mobility management query (MMQ) and that includes a serving switch identifier. The MSF allocates a global title address (GTA) from a pool of GTAs and stores a correlation between the allocated GTA and the originating SMSC. The MSF replaces the serving switch identifier in the MMR with the allocated GTA and routes the modified MMR. The MSF then receives a messaging service message (MSM) that is addressed to the allocated GTA and that includes the purported originating SMSC. If the purported originating SMSC does not match the SMSC to which the GTA is correlated, the MSM is discarded.
