Abstract
The present application relates to of the communication field and discloses a method, device and system for implementing frequency point switch based on CR. The method comprises: determining, by a cognitive base station, a candidate working frequency point for UE deployed in a cognitive frequency band; then sending to the UE broadcast information which at least carries the candidate working frequency point and instructing the UE to switch from the working frequency point currently used thereby to the candidate working frequency point by way of a frequency point switching command. In this way, the UE deployed in the cognitive frequency band can achieve frequency point switch quickly and accurately according to the instruction from the cognitive base station when an incumbent user accesses the working frequency point currently used by the UE, effectively avoiding interference to the incumbent user and thereby ensuring the service performance and service continuity of the system. The present application also discloses a corresponding device and system.
