Abstract
An interconnection device for interconnecting two sub-networks, on which UPnP devices are connected: determines actual IP addresses and port numbers of servers of the UPnP device; allocates a port number to each server, establishes a connection with a UPnP device of the femtocell and a connection with a UPnP device of the local area network; replaces, in frames received via one of said connections, each actual server IP address and port number allocated by the interconnection device to said server; and replaces, in frames received via one of said connections, each actual IP address and port number with an IP address of the interconnection device to said server; and replaces, in said received frames, each IP address of the interconnection device and port number allocated by the interconnection device to a server with the IP address and port number of the corresponding server.
