Wireless communication system, coexistence manager installed in said system, and method for wireless communication

摘要

Disclosed is a wireless communication system capable of avoiding interference even when a network including a secondary user coexists. The wireless communication system includes a primary user belonging to a first network, a first secondary user belonging to a second network, and a coexistence manager (CM). The coexistence manager (CM) acquires information relating to spectrum holes that are, at least temporarily, not in use by the primary user. In addition, the coexistence manager (CM) determines whether or not usage of the spectrum holes by the first secondary user causes interference. If the determination result is that interference is caused, coexistence manager (CM) notifies to this effect a second secondary user belonging to a third network, which differs from the second network.

主权项

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.
