Abstract

The embodiment of the invention discloses a spectrum allocation method and a spectrum allocation system, a base station and user equipment. The spectrum allocation method comprises the following steps of: sending an indicating message to the user equipment, and informing the user equipment of a preset switching time point in an implicit or explicit mode, so that the user equipment is synchronized to a service cell of an updated carrier parameter after the preset switching time point, wherein the indicating message comprises the updated carrier parameter; and switching on the preset switching time point, so that the service cell of the user equipment uses the updated carrier parameter, wherein the carrier parameter comprises the carrier frequency and / or carrier bandwidth. By the embodiment of the invention, the dynamic allocation of long term evolution (LTE) system bandwidth and the center frequency is realized, the problems of drop-call of the user equipment or no service cell and the like in the process of LTE spectrum allocation are solved, and the service quality is improved.
