<p>The present invention discloses a dynamic spectrum allocation method, a central control unit, a base station and a spectrum allocation system. The dynamic spectrum allocation method includes the following steps: a bandwidth request message sent by a base station is received, the bandwidth request message comprising radio frequency capability of the base station, a bandwidth requirement on an un-licensed band of the base station and a licensed band set of the base station; a spectrum allocation solution is determined according to the radio frequency capability of the base station, the bandwidth requirement on the un-licensed band of the base station, the licensed band set of the base station and an obtained current idle un-licensed band set; a bandwidth request response message with the spectrum allocation solution is transmitted, the spectrum allocation solution being used for indicating un-licensed band information allocated to the base station to use and the requirement of aggregating the bandwidth request of at least one licensed band of the licensed band set of the base station on the un-licensed bands allocated to the base station to use. The embodiment of the present invention also includes a central control unit, a base station and a spectrum allocation system, enabling to effectively reduce invalidation probability of the spectrum allocation solution.</p> |
