Patent ID: 7349413

Claim:
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.
