摘要

PURPOSE: A remote entrance and exit control system through a mobile communication network, and a method thereof are provided to confirm a visit of a visitor in user's absence and open an entrance door for the visitor as occasion demands. CONSTITUTION: A door lock terminal(100) is installed at an entrance door. If a visitor presses a visit notifying button, the door lock terminal(100) transmits an SMS(Short Message Service) to a telephone number of a user which is preliminarily set to report a visit of the visitor. If the user connects to a call, the door lock terminal(100) mediates the telephone call between the visitor and the user. If receiving a door locking release control signal from the user, the door locking terminal releases locking of the entrance door. A mobile communication terminal(200) of the user receives the SMS from the door lock terminal(100) for displaying the SMS. If the user selects the call with the door lock terminal(100), the mobile communication terminal(200) executes the telephone call. If the user selects to release locking, the mobile communication terminal(200) transmits the door locking release control signal to the door lock terminal(100). A mobile communication network(300) relays communication between the door lock terminal(100) and the mobile communication terminal(200).
