Abstract:
A method includes receiving an ingress Diameter message related to a mobile subscriber from a MME located in a non-home network, sending a RIR message containing a mobile subscriber identifier to a HSS in a home network of the mobile subscriber, receiving identification information identifying a MME in the home network that conducted a most recent attachment of the mobile subscriber, utilizing the identification information to send an IDR message containing the mobile subscriber identifier to the identified MME, receiving an IDA message containing attachment timestamp data corresponding to the most recent attachment of the mobile subscriber in the home network, determining a transit time using the UE attachment timestamp data and timestamp information corresponding to the ingress Diameter message, and analyzing the transit time to determine if the ingress Diameter message is to be designated as a suspicious ingress message.

Claim (Index 15):
A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer controls the computer to perform steps comprising:\n receiving, by a DEA, an ingress Diameter message related to a mobile subscriber from a mobility management entity (MME) located in a non-home network, wherein the ingress Diameter message is an authentication information request (AIR) message or a Diameter update location request (ULR) message; sending a routing information request (RIR) message containing a mobile subscriber identifier associated with the mobile subscriber to a home subscriber server (HSS) in a home network of the mobile subscriber; receiving identification information identifying a mobility management entity (MME) in the home network that conducted a most recent attachment of the mobile subscriber in the home network; utilizing the identification information to send an insert subscriber data request (IDR) message containing the mobile subscriber identifier to the identified MME; receiving, from the MME, an insert subscriber data acknowledgement (IDA) message containing user equipment (UE) attachment timestamp data corresponding to the most recent attachment of the mobile subscriber in the home network; determining, by the DEA, a transit time of the user equipment using the UE attachment timestamp data and timestamp information corresponding to the ingress Diameter message; and analyzing the transit time of the user equipment to determine if the ingress Diameter message is to be designated as a suspicious ingress message, wherein analyzing the transit time includes comparing the transit time of the user equipment to a predefined minimum transit time between two countries.
