A flow profile information control system for dynamically controlling upstream traffic in an IP packet network and a method thereof are provided to dynamically control upstream traffic by defining control interfaces between an access network policy control server and a terminal control server and controlling the flow profiles of subscriber terminals through the terminal control servers on the basis of the control interfaces. A flow profile information control system for dynamically controlling upstream traffic in an IP packet network comprises a subscriber DB(118), a subscriber information management server(114), and an access network policy control server(110). The subscriber DB(118) stores subscriber configuration information containing the ID and service profile information of each subscriber and the URL information of each terminal control server(112). Based on a subscriber's network access request, the subscriber information management server(114) extracts the URL information of a terminal control server(112), which manages the subscriber, from the subscriber DB(118). The access network policy control server(110) is connected with the terminal control servers(112) through control interfaces(110a,112a). Whenever a modification for the flow profile of a subscriber terminal is required, the access network policy control server(110) provides flow control data and the subscriber ID of the subscriber terminal to an associated terminal control server(112) through the control interfaces.
