9. A domain system in which a remote UPnP controller controls universal plug and play (UPnP) devices in a domain, the system comprising:
-
CP proxy means for transmitting a UPnP packet received from a UPnP device through the Internet and transmitting a received UPnP packet to the UPnP device; and
CD proxy means for transmitting the UPnP packet received from the UPnP controller to the CP proxy means and transmitting the UPnP packet received from the CP proxy means to the UPnP controller, wherein the CD proxy means stores a UPnP device list received in response to requesting the CP proxy means for the UPnP device list, and when receiving a search request from the UPnP controller, searches the UPnP device list and generates a response packet.
