Abstract
A method and apparatus for reducing spectrum interference between wireless networks. This is realized by arranging at least one sub-coordinating apparatus, namely, a monitoring apparatus, in respective wireless network, and by arranging a coordinating apparatus, namely, an allocation apparatus in the whole network. Wherein, the sub-coordinating apparatus monitors the spectrum utilization situation of the wireless network where it is located, reports it to the coordinating apparatus, and requests the coordinating apparatus for spectrum resource when new spectrum resource is needed. The coordinating apparatus maintains the spectrum utilization information of each wireless network, and allocates appropriate spectrum resource to the sub-coordinating apparatus which requests spectrum resource based on the maintained information. Therefore, the interference of inter-wireless networks is reduced or even avoided through such overall management that the coordinating apparatus allocates corresponding spectrum resources to a plurality of wireless networks capable of sharing spectrum resources.
