Patent ID: 8085691

Claim:
A wireless communication system, comprising: a plurality of wireless communication apparatuses; and a plurality of wireless networks that coexist in a same frequency band, each one of the wireless networks including an associated portion of the plurality of wireless communication apparatuses with one of the wireless communication apparatuses associated with that wireless network operating as a control station for that wireless network, the control station of each such wireless network initially performing time slot assignment within every predetermined transmission frame period to each one of said wireless communication apparatuses of that wireless network independent of the control stations of the other such networks, the control stations of each of said wireless networks comprising: signal detecting means for detecting a signal from another of said plurality of wireless networks, for detecting address information of the control station of the another wireless network from the detected signal, and for comparing the address information of that control station with the address information of the control station of the another wireless network; time slot analyzing means for, in response to the address information of that control station being newer than the address information of the control station of the another wireless network, analyzing a transmission time slot on which guaranteed time slot transmission is performed in the another of said wireless networks based on a signal detected by said signal detecting means; and time slot assigning means that, in response to the address information of that control station being newer than the address information of the control station of the another wireless network, avoids assigning a transmission time slot on which guaranteed time slot transmission is performed in the another of said wireless networks to a wireless communication apparatus in that wireless network.
