| 1. An Internet Protocol (IP) charging and rating gateway system comprising:
a proxy server for connection to an Authentication, Authorization, and Accounting (AAA) server and an access gateway; said
proxy server configured to reside between said AAA server and said access gateway; said proxy server further configured to
emulate said access gateway such that when said AAA server communicates with said proxy server said AAA server presupposes
said AAA server is communicating with said access gateway; said proxy server further configured to emulate said AAA server
such that when said access gateway communicates with said proxy server said access gateway presupposes said access server
is in communication with said AAA server;
an IP classification engine for connection between a data network and said access gateway; said IP classification engine for
classifying IP packets according to the protocol of each of said packets; said IP packets originating from said data network
and destined for a subscriber device via said access gateway; and,
a gateway controller connected to said proxy server and said IP classification engine for selectively instructing said IP
classification engine to permit or deny the flow of IP packets between said data network and said access gateway.
