Embodiments of the present invention provide a method, an apparatus and a system for managing a dynamic spectrum. The method includes: receiving occupancy information of spectrum resources that is sent by a sensing device; determining, according to the occupancy information of the spectrum resources, a first spectrum resource occupied by a fixed authorized user, a second spectrum resource occupied by a non-fixed authorized user, and a third spectrum resource not occupied by any user in the spectrum resources; and configuring, according to occupancy information of the second spectrum resource and occupancy information of the third spectrum resource, a spectrum resource available for a communications node, where the first spectrum resource is an unavailable spectrum resource. In the embodiments of the present invention, occupancy information of a spectrum resource of a fixed authorized user and occupancy information of a spectrum resource of a non-fixed authorized user are obtained by using a sensing device to configure a spectrum resource available for a communications node. Therefore, in the embodiments of the present invention, the spectrum resource available for the communications node can be timely managed according to occupancy information of the spectrum resource. |
