BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a door lock system. 
         [0003]    2. Background Art 
         [0004]    In general, electronic door locks have been provided in order to make up for the weakness of traditional door locks to which keys are used and to enhance convenience in use. 
         [0005]    Recently, studies on a door lock system for preventing theft of a key for the door lock and an illegal use of the entrance door and for maximizing security and convenience by controlling the door lock using a user&#39;s own terminal have been continued. 
       SUMMARY OF THE INVENTION 
       [0006]    Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a door lock system, which can control a door lock using a user&#39;s own terminal without regard to kinds of the user&#39;s terminal and mobile service providers that the user&#39;s terminal has been registered. 
         [0007]    It is another object of the present invention to provide a door lock system, which can control the door lock remotely when there is a visitor who does not have the terminal whose phone number is registered in the door lock. 
         [0008]    It is a further object of the present invention to provide a door lock system, which can control the door lock using the user&#39;s own terminal without regard to kinds of the terminal if the terminal can execute a door lock application. 
         [0009]    It is a still further object of the present invention to provide a door lock system, which can preclude a person, who does not have a registered terminal, from controlling the door lock because identification information of a terminal of a person who will gain admission has been registered in advance. 
         [0010]    It is another object of the present invention to provide a door lock system, which can preclude a person, who does not have a registered terminal, from controlling the door lock because identification information of a terminal of a person who will gain admission has been registered in advance, and which can prevent the person, who does not have the registered terminal, from stealing the registered terminal and illegally using the door because a secrete access number has been registered in advance. 
         [0011]    It is a further object of the present invention to provide a door lock system, which can preclude a person, who does not have a registered terminal, from controlling the door lock because identification information of a terminal of a person who will gain admission has been registered in advance, which prevents communication between the door lock and a terminal to which a network key of the door lock was not set because the network key of the door lock has been set to the user&#39;s terminal in advance, and which can prevent the person, who does not have the registered terminal, from stealing the registered terminal and illegally using the door because a secrete access number has been registered in advance, thereby maximizing security. 
         [0012]    To achieve the above objects, the present invention provides a door lock system including: an entrance door provided at one side of a building; a door lock provided at one side of the entrance door for controlling opening and closing of the entrance door; and a terminal for providing a communication signal to the door lock through communication with the door lock. 
         [0013]    The door lock system according to the present invention has the following effects. 
         [0014]    First, the door lock system can control the door lock using the user&#39;s own terminal without regard to kinds of the user&#39;s terminal and mobile service providers that the user&#39;s terminal has been registered. 
         [0015]    Second, the door lock system can control the door lock remotely when there is a visitor who does not have the terminal whose phone number is registered in the door lock. 
         [0016]    Third, the door lock system can control the door lock using the user&#39;s own terminal without regard to kinds of the terminal if the terminal can execute a door lock application. 
         [0017]    Fourth, the door lock system can preclude a person, who does not have a registered terminal, from controlling the door lock because identification information of a terminal of a person who will gain admission has been registered in advance. 
         [0018]    Fifth, the door lock system can preclude a person, who does not have a registered terminal, from controlling the door lock because identification information of a terminal of a person who will gain admission has been registered in advance, and prevent the person, who does not have the registered terminal, from stealing the registered terminal and illegally using the door because a secrete access number has been registered in advance. 
         [0019]    Sixth, the door lock system can preclude a person, who does not have a registered terminal, from controlling the door lock because identification information of a terminal of a person who will gain admission has been registered in advance, prevent communication between the door lock and a terminal, to which a network key of the door lock was not set, because the network key of the door lock has been set to the user&#39;s terminal in advance, and prevent the person, who does not have the registered terminal, from stealing the registered terminal and illegally using the door because a secrete access number has been registered in advance, thereby maximizing security.
