A non-volatile memory may store a key used for encryption in order to encrypt and transmit data during data communication between the interphone control devices. The non-volatile memory may store information for the second interphone control device 142 to confirm the authority of the user terminal.

The second interphone control device 142 may forward the message received from the first interphone control device 141 to the user terminal in an error-compatible state, or may decode the message to the user terminal. The second interphone control device 142 may encrypt at least one of the door open / close message and the user response message received from the user terminal and transmit the encrypted message to the first interphone control device 141.

When the second interphone control device 142 transmits a message to the user terminal, the second interphone control device 142 may transmit a message to all the user terminals or may transmit the message only to specific user terminals. A specific user terminal is a specific user terminal configured to receive a message according to a user's setting or a user terminal determined that the second interphone control device 142 has authority when transmitting a message. In this case, the second interphone control device 142 can always transmit a message to the master user terminal.

The second interphone control device 142 may transmit a message including a paging message only to a user terminal having access authority. The second interphone control device 142 can confirm the rights of the user terminal using the rights information stored in the non-volatile memory, and can transmit a message including the paging message only to the authorized user terminal. The second interphone control device 142 may be configured to store the private key or the group key stored in the user terminal in a manner consistent with the key stored in the nonvolatile memory of the second interphone control device 142, ) Or the group key (key), the authority of the user terminal can be confirmed by the calculated value. The second interphone control device 142 determines the private key or the group key to correspond to the identification number unique to the user terminal such as the identification number of the user terminal or the telephone number of the user terminal, And can be stored in the second interphone control device 142.

The user response message may be voice or image data of the user. The user terminal may transmit at least one of the door open / close message and the user response message to the second interphone control device 142 using the wireless AP 150. [ The door opening / closing message may include at least one of an identifier of a door to be opened and closed and an identifier indicating opening and closing of the door. The user terminal may encrypt and transmit the above door open / close message and user response message. In addition, the user terminal may send its own identification, such as its own private key or group key or device number or telephone number, to the second interphone control device 142.

The user terminal may be a dedicated terminal device, a smart phone, a tablet, and a personal computer. An application is installed in the user terminal to display a call message of a visitor to the user, receive a control input of a user who generates a door open / close message or sets an authority by receiving a user input.

The master user terminal 161 is a user terminal having a master authority, and sets the authority of the general user terminal. For example, the master user terminal 161 may set the authority between the general user terminal and the master user terminal, and may set a private key and a group key for confirming the authority of the user terminal in the user terminal and the interphone control device, And the authority time of the group key. The master user terminal 161 may inquire log information such as a call message generation history, a door open / close message generation history, and the like using an application.

The user terminal 606 may add a door open / close message to the response message (S632), add the door phone identification information (S633), and may add the user terminal identification information (S634). In addition, the user terminal 606 may encrypt the response message using the encryption key (S635). The encryption key may be any of a private key, a group key, and a preset encryption key. Then, the user terminal 606 transmits a response message to the wireless AP 605 (S636).

Next, the wireless AP 605 transmits a response message to the second interphone control device 604 (S637). Step S637 may be omitted so that the user terminal 606 may directly transmit a response message to the second interphone control device 604 using Wi-Fi, Bluetooth, or the like.

Next, the second interphone control device 604 transmits a response message to the first interphone control device 603 (S638). The first interphone control device 603 can decode the response message (S639). In step S640, the first interphone control device 603 extracts at least one of voice data, image data, door open / close messages, and door phone identification information from the response message. The first interphone control device 603 confirms the user terminal authority (S641). Step S641 may be performed before steps S639 and S640. In addition, step S641 may be omitted or it may be performed that the second interphone control device 604 does not forward the response message received from the unauthorized user terminal to the first interphone control device 603. [

Next, the first interphone control device 603 transmits the voice and image data of the user to the interphone 602 (S642), and the interphone 602 transmits the voice and image data of the user to the door phone 601 (S643). The door phone 601 can display the user's voice and image data to the visitor.

Next, the first interphone control device 603 transmits a door open / close message to the interphone 602 (S644). The interphone 602 transmits a door open / close message to the door phone 601 (S645). The door phone 601 can control the door opening / closing device using a door open / close message. Alternatively, the first interphone control device 603 may directly transmit the door open / close message to the door phone 601 (S646), or may transmit the door open / close message directly to the door open / close device. Steps S642 and S643 and steps S644 to S646 may be performed independently or in parallel.
