An address translator of a first communication station transmits to a second communication station a transmission frame that is sent from a terminal in the first communication station to a terminal in the second communication station and includes the virtual private address of the terminal, after the address translator translates the virtual private address into a corresponding real private address, while it determines the global address of the second communication station based on the virtual private address and applies it to the frame. The address translator of the second communication station that received the frame sends a content of the transmission frame to the terminal indicated by the real private address included in the transmission frame.
