ABSTRACT:
A method, device and system for allowing a mobile communication device, such as a DLNA/UPnP device, to continue to communicate with its local network, even when the mobile device leaves or loses contact with the local network. The method includes providing information to a remote access server to create a virtual mobile device in a local network. The virtual device communicates with other devices within the local network as if it is the actual mobile device. The remote access server is configured to route data packets between the virtual device and the mobile device via a second network that does not rely on the mobile nodes connection to the local network. A public IP address of the remote access server provided to the mobile device before the device leaves the local network is used to communicate with the virtual device via an IP-based public network coupled to the local network.
