Abstract
An apparatus and method for managing and controlling UPnP devices in a home network over an external Internet network. The apparatus comprises a client connected to the external Internet network, and a UPnP proxy server for controlling and managing the UPnP devices in the home network. The client includes a stub for providing the same application program interface (API) as a UPnP API to a user, managing information of the UPnP devices and processing a device control command from the user, and a push client for transferring the device control command processed by the stub to the UPnP proxy server and an event message from the UPnP proxy server to the stub, respectively. The UPnP proxy server includes a bridge for managing the UPnP devices in the home network and controlling a specific one of the UPnP devices in response to the device control command from the client, and an agent for transferring the device control command from the client to the bridge and a result of execution of the device control command and the event message from the bridge to the client, respectively.
