Methods, systems, and computer readable media for using a diameter routing agent (DRA) to obtain mappings between mobile subscriber identification information and dynamically assigned internet protocol (IP) addresses and for making the mappings accessible to applications

A system for using a Diameter routing agent (DRA) to obtain mappings between mobile subscriber identification information and dynamically assigned Internet protocol (IP) addresses and making the mappings accessible to applications, the system comprising:

• a DRA including:
• a Diameter message processor for receiving a Diameter message containing a dynamically assigned Internet protocol (IP) address and mobile subscriber identification information;
• a Diameter routing module for routing the received Diameter message;
• and
• a Diameter message copy module, located within the DRA, for copying the IP address and the mobile subscriber identification information from the message and for making a mapping between the dynamically assigned IP address and the subscriber identification information accessible to applications, wherein making a mapping between the dynamically assigned IP address and the mobile subscriber identifier available to applications includes storing the mapping between the dynamically assigned IP address and the mobile subscriber identifier in a database upon receipt of the Diameter message, wherein the Diameter message copy module in the DRA is separate from the Diameter routing module in the DRA.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a computer control the computer to perform steps comprising:

• receiving, by a Diameter routing agent (DRA), a Diameter message containing a dynamically assigned Internet protocol (IP) address and mobile subscriber identification information;
• routing, by the DRA, the received Diameter signaling message;
• copying, by the DRA, the IP address and the mobile subscriber identification information from the message;
• and
• making, by the DRA, a mapping between the dynamically assigned IP address and the subscriber identification information accessible to applications, wherein making a mapping between the dynamically assigned IP address and the mobile subscriber identifier available to applications includes storing the mapping between the dynamically assigned IP address and the mobile subscriber identifier in a database upon receipt of the Diameter message, wherein the copying is performed by a Diameter message copy module in the DRA that is separate from a Diameter routing module in the DRA that performs the routing.
