System and method employing strategic communications between a network controller and a security gateway

摘要

A system for enhancing functionality of a network. In a specific embodiment, the system employs strategic communications between a network controller and a security gateway. The strategic communications occur via a feedback communications channel between the network controller and the security gateway. The feedback communications channel facilitates transferring security information, such as International Mobile Subscriber Identity (IMSI) and other information, between the network controller and the security gateway. The security information may facilitate enabling the SGW to make intelligent decisions as to how to treat a client communications session. In the specific embodiment, the feedback communications channel includes an intervening Authentication, Authorization, and Accounting (AAA) server that is coupled between the UMA and the network controller.
