Abstract

A method is provided for controlling a mobile device capable of accessing an AP card of a DTV located in one independent space among a plurality of independent spaces physically separated from one another. The method includes accessing a management server using the AP card, downloading an in-room control application from the management server, requesting a unique access code from the management server using the AP card if the downloaded in-room control application is executed, wherein the unique access code is mapped to both an ID of the AP card and an available term assigned to a current guest staying in the independent space, receiving the unique access code from the management server, and transmitting a command signal for changing a status of a controllable device contained in the independent space and the received unique access code to the AP card of the DTV.

Claims

1. A method for controlling a mobile device capable of accessing an access point (AP) card of a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another, the method comprising:

accessing a management server using the AP card;

downloading an in-room control application from the management server;

requesting an authentication to the AP card, wherein the AP card transmits a lock request signal to the management server, receives a lock signal and transmits an encrypted AP card ID using the lock signal to the management server;

executing the downloaded in-room control application enabling a user to control device of the independent space using the AP card and DTV, wherein the AP card supports a multi-protocol interface to control devices of the independent spaces and the DTV displays a list and positions of the devices;

requesting a unique access code from the management server using the AP card, wherein the unique access code is mapped to both an identifier (ID) of the AP card and an available term assigned to a current guest staying in the independent space;

receiving the unique access code from the management server, if the management server completes verification by decrypting the encrypted AP card ID; and

transmitting a command signal for changing a status of a controllable device contained in the independent space and the received unique access code to the AP card of the DTV.

2. The method according to claim 1, further comprising:

transmitting the unique access code to the management server at an exterior area of the independent space, wherein the exterior area is located at an Internet accessible area; and

receiving the current room status information from the management server that has received the current room status information of the independent space from the AP card.

3. The method according to claim 1, further comprising:

transmitting the unique access code and the command signal for changing a status of the controllable device contained in the independent space to the management server at an exterior area of the independent space, wherein the exterior area is located at an Internet accessible area; and

transmitting the command signal from the management server to the AP card, and receiving the current room status information from the management server that has received the current room status information of the independent space from the AP card.

4. The method according to claim 1, wherein the independent spaces physically separated from one another correspond to several rooms contained in one hotel.
