Terminal shift management system and method thereof

Abstract

The present invention relates to a terminal control system, and more particularly, to a system and a method which allows a user to shift an IP service from a terminal to which the service is currently provided to a user's other terminal, thereby enabling the user to continuously using the IP service without disconnection. The system comprises: an authentication authorization accounting (AAA) interface unit which receives unique information having fixed properties with respect to a terminal authenticated by a subscriber terminal authentication system and a user of the authenticated terminal; a terminal interface unit which receives status information having variable properties with respect to the authorized terminal and a currently used service; a unique information managing unit which stores and manages the unique information; a status information managing unit which stores and manages the status information; and a terminal shift management control unit which provides information regarding terminals available for the current service with reference to the unique information and the status information, when there is a terminal shift request, generates service session information which is required when the currently used service is sent to a terminal selected from the information and sends the generated service session information to the selected terminal to which the service is to be shifted. Accordingly, the user of the terminal can conveniently change the terminal to continuously use the IP service without disconnection while using the IP service.
