Method and device for distributing spectrum resources

The invention discloses a method and a device for distributing spectrum resources. The method for distributing the spectrum resources comprises the following steps of: dividing spectrum resources which can be used into basic spectrum resources and shared spectrum resources, monitoring the shared spectrum resources when the capacity of wireless access equipment needs to be expanded, and also using the idle shared spectrum resources. By the method disclosed by the invention, all the spectrum resources distributed to a wireless access technology to which a plurality of wireless access equipment belongs for use are flexibly shared by the wireless access equipment, and the condition that continuous business service is provided to a terminal is ensured by the wireless access equipment through the basic spectrum resources. Meanwhile, a business with high rate is also provided by the time-sharing shared use of the shared spectrum resources, and the requirement of the business to large bandwidth is met. Moreover, the phenomenon of interference between the wireless access equipment cannot be caused.
