Accordingly, a control point inserts attribute information on a device designated by a user in addition to information on a device type, a service type, or the like into a search message that is multicasted to search for a UPnP message, and a UPnP device which receives the search message determines whether or not the received attribute information corresponds to an attribute of the UPnP device with reference to a device description and a service description, and transmits a response message according to a result of the determining. Therefore, network traffic that occurs in an operation of searching for a UPnP device can be reduced, and a user can easily and rapidly search for a desired UPnP device.
