Patent ID: 7313153

Claim:
A wireless communication control apparatus in a wireless network including a plurality of wireless communication apparatuses, wherein data transmission is performed by allocating a transmission channel in a transmission frame defined by a beacon signal to each of the plurality of wireless communication apparatuses, the wireless communication control apparatus processing a channel allocation request from each of the plurality of wireless communication apparatuses, the wireless communication control apparatus comprising: channel allocation request receiving means for receiving the channel allocation request from each of the plurality of wireless communication apparatuses, the channel allocation request relating to transmission using a channel allocated in response to the channel allocation request; transmission information determining means for determining characteristics of information to be transmitted, by each of the wireless communication apparatuses using the channel allocated in response to the channel allocation request; channel allocation means for determining a position of a transmission channel in the transmission frame to be allocated to the information to be transmitted in accordance with determined characteristics of the information to be transmitted; channel allocation information transmitting means for transmitting channel allocation information to each of the plurality of wireless communication apparatuses that sent the channel allocation request; wherein the transmission information determining means determines whether an amount of channel space requested by each of the plurality of wireless communication apparatuses to transmit information is constant, and the channel allocation means allocates in response to each channel allocation request transmission using the allocated channel in which the amount of channel space requested by each of the wireless communication apparatuses is constant and is allocated from a position towards an end of the transmission frame; wherein the allocated channel corresponds to a guaranteed time slot having a guaranteed transmission area followed by a redundant area.
