Patent ID: 7907566

Claim:
A system comprising a plurality of access points and a management apparatus that manages the plurality of access points, wherein the management apparatus comprises: a holding unit adapted to hold management information that indicates channels used by each of the plurality of access points and a remaining bandwidth for each channel; a receiving unit adapted to receive a bandwidth assigning request, that indicates a bandwidth amount to be maintained, from a terminal via a first access point; a determining unit adapted to determine, based on the remaining bandwidth of a first channel being used by the first access point and the bandwidth amount indicated in the bandwidth assigning request, whether or not bandwidth amount indicated in the bandwidth assigning request is assignable to the first channel being used by the first access point; a selecting unit adapted to select a second access point that is using a second channel, whose currently assigned bandwidth amount can be assigned to the first channel of the first access point, and to which a total of a bandwidth amount assigned to the first channel by the first access point and a bandwidth amount designated by the bandwidth assigning request can be assigned, in case that the determining unit determines that the bandwidth amount indicated in the bandwidth assigning request is not assignable to the first channel being used by the first access point; and an exchanging unit adapted to exchange the first channel being used by the first access point and the second channel being used by the second access point selected by the selecting unit, so that the first access point uses the second channel that had been used by the second access point and the second access point uses the first channel that had been used by the first access point.
