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 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 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.

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 a mapping between the dynamically assigned IP address and the subscriber identification information accessible to applications.
