Method and system for reconfiguring cellular network resource in cognitive radio

The invention discloses a method for reconfiguring a cellular network resource in cognitive radio. The method comprises the following steps that: a reconfiguring system obtains a resource capable of being utilized; when a triggering condition is met, a base station or the reconfiguring system triggers a resource reconfiguring process; and the reconfiguring system sends a resource reconfiguring command to carry out resource reconfiguration. The invention further discloses a system for reconfiguring the cellular network resource in the cognitive radio. With the adoption of the method and the system, reconfiguration sub-phases in the reconfiguring process can be divided so that the resource reconfiguring process of a cognitive system is distinct and structuralized, and the method and the system are beneficial for optimizing the whole performance of the reconfiguring process and improving the reconfiguring efficiency of the resource of the base station.
