Method for controlling devices based on nfc and device control system using the same

A device control system based on NFC, comprising:

• a first computer-readable recording medium configured to store a program including instructions for causing a smart terminal to:
• perform a hand-over to a secondary network when the smart terminal is connected to an external service device through NFC;
• execute a web contents execution program;
• receive control codes from the service device by requesting the control codes;
• and display a control/service screen of the service device on the web contents execution program by utilizing the control codes, wherein the web contents execution program transmits a request defined in the control codes to the service device when a user manipulation on the control/service screen is detected;
• and
• a second computer-readable recording medium configured to store a program including instructions for causing a service device to:
• perform a hand-over to the secondary network when the service device is connected to an external smart terminal through NFC;
• provide control codes in response to a request from the smart terminal;
• and execute an operation corresponding to a request defined in the control codes when the request is provided from the smart terminal.

A device control system based on NFC, comprising:

• a first computer-readable recording medium configured to store a program including instructions for causing a smart terminal to:
• perform hand-over to a secondary network when the start terminal is connected to an external service device through NFC;
• and execute a browser, wherein the browser accesses a web contents providing program of the service device to request device control web contents of the service device, loads the device control web contents to display a control/service screen of the service device when receiving the device control web contents from the service device, and transmits a request defined in a user manipulation point on the web contents to the web contents providing program of the service device, when detecting a user manipulation on the control/service screen;
• and
• a second computer-readable recording medium configured to store a program including instructions for causing a service device to:
• perform a hand-over to the secondary network when the service device is connected to an external smart terminal through NFC;
• and provide a web contents providing program, wherein the web contents providing program provides device control web contents in response to a request from the smart terminal, and performs an operation corresponding to a message defined in the device control web contents, when the message is provided from the smart terminal.

• perform a hand-over to a secondary network when the smart terminal is connected to an external service device through NFC;
• and execute a browser, wherein the browser accesses a web contents providing program of the service device to receive and install an extension module from the service device, and displays a control/service screen based on the installed extension module, and the extension module transmits a request based on a user manipulation and a function execution result value of the smart terminal to the web contents providing program of the service device, when a user manipulation on the control/service screen is detected;
• and
• a second computer-readable recording medium configured to store a program including instructions for causing a service device to:
• perform a hand-over to the secondary network when connected to an external smart terminal through NFC;
• and provide a web contents providing program, wherein the web contents providing program provides an extension module for device control in response to a request from the smart terminal and performs an operation corresponding to a request defined in the extension module when the request is provided from the smart terminal.
