Abstract

A method, system, and device for controlling a device connected to a UPnP (universal plug and play) home network using the Internet is provided. This method includes: subscribing to the external device outside the UPnP home network and informing the external device of control information about the device connected to the UPnP home network; converting a third-party notification message about control of the device connected to the UPnP home network, the third-party notification message being received from the external device via the Internet, into a control message with respect to a device that provides a web-based user interface or a device that provides no web-based user interfaces; and transmitting the control message to the device that provides a web-based user interface or the device that provides no web-based user interfaces.

1 . A method of controlling a device connected to a UPnP (universal plug and play) home network based on a signal transmitted by an external device outside the UPnP home network, the method comprising:
 subscribing the device connected to the UPnP home network to the external device outside the UPnP home network and informing the external device of control information about the device connected to the UPnP home network;   receiving a third-party notification message about control of the device connected to the UPnP home network, from the external device via the Internet,   converting the third-party notification into a control message for the device connected to the UPnP home network; and   transmitting the control message to the device connected to the UPnP home network, wherein the device connected to the UPnP home network is a device that provides a web-based user interface or a device that provides no web-based user interface.
