Abstract
The present invention relates to method and apparatus for enabling to request querying and/or controlling operations remotely to a device on a home network via Internet. In a method in accordance with the present invention, a device search message is transmitted to a plurality of devices connected to a local network, and device information is created or modified based on whether there are responses to the message from the devices. Afterwards, when a device search message is received a responding message to the received message is transmitted for a device or devices contained in the device information. Whereby, possible communication errors occurred by long-time delay (caused by traveling across large-area network and local network) of a search message can be prevented.
