[Patent application number] 20100030882 [Published] 02-04-2010 [Description] 
MANAGEMENT APPARATUS, COMMUNICATION APPARATUS, CONTROL METHOD, AND PROGRAM - It has been difficult for a management apparatus to make a communication apparatus change a communication channel in consideration of a remaining communication band of a network so as to set an appropriate communication channel. Further, setting the appropriate communication channel has been an enormous load placed on a communication apparatus provided with not many processing resources including a small CPU capacity, a small memory, and so forth. Therefore, the present invention allows for setting an appropriate communication channel ready for the remaining communication band of the network. Further, the present invention allows for reducing the load placed on the communication apparatus for setting the appropriate communication channel. Therefore, a management apparatus managing the network determines a communication channel satisfying a requested communication band and notifies at least a transmission apparatus and/or a reception apparatus of a change to the communication channel.
