Abstract:
1. A wireless communication system including a first network and a second network, comprising: a primary user belonging to the first network; a first secondary user belonging to the second network; and a coexistence manager (CM) installed so as to be able to communicate in the first network and the second network, wherein the coexistence manager (CM) comprises: acquiring means for acquiring information regarding spectrum holes which are not at least temporarily used by the primary user; determining means for determining whether usage of the spectrum holes by the first secondary user causes interference in the first network or not; and notifying means, when the determining means determines that interference occurs in the first network, for notifying a second secondary user belonging to a third network which is different from the second network that interference occurs in the first network, thereby enabling the second network and the third network to coexist in the first network.
