Abstract
A device control apparatus which monitors a state change of a device independently without communication with a client apparatus. A device server as the device control apparatus monitors the state of a device locally connected thereto, using a definition file and a trigger detection algorithm for monitoring the state of the device, and detects a state change of the device. When a state change of the device is detected, the device server transmits a trigger notification indicative of the detection of the state change to the client apparatus. The device server starts a session with the client apparatus having received the trigger notification and relay data communication with the device, of which the state change has been detected. When the session with the client apparatus is disconnected, the device server restarts monitoring of the state of the device.
