| 1. A method for communicating between coordinator-based wireless networks connected through a backbone network, comprising:
managing identification information of multiple coordinator-based wireless networks;
providing a network device with the identification information of a coordinator-based destination wireless network to which
a destination network device belongs;
converting a frame containing the identification information, which has been received from the network device, to a frame
supported by the backbone network; and
transmitting the convened frame to the backbone network,
wherein the managing of the identification information comprises:
providing the backbone network with a packet containing the identification information of a the coordinator-based destination
wireless network within a predetermined period;
receiving a packet containing the identification information of another coordinator-based wireless network from the backbone
network, extracting the identification information from the received packet, and updating the identification information;
and
informing a coordinator in the coordinator-based destination wireless network of overlapping information when the identification
information of the coordinator-based destination wireless network overlaps with already managed identification information
of said another coordinator-based wireless network.
