Claim:
1. A method of resource reconfiguration for a cognitive-radio system, comprising: acquiring, by a reconfiguration module of a wireless communication system, a reconfiguration command according to a received spectrum refarming indication or by monitoring a network condition of the wireless communication system; and sending, by the reconfiguration module, the reconfiguration command to a base station, and implementing resource reconfiguration by executing the reconfiguration command via the base station, wherein the acquiring, by the reconfiguration module of the wireless communication system, the reconfiguration command according to the received spectrum refarming indication or by monitoring the network condition of the wireless communication system comprises: acquiring, by the reconfiguration module of the wireless communication system, the spectrum refarming indication and information on spectrum utilization by exchanging information with a policy control center or by monitoring the network condition; and acquiring, by the reconfiguration module, the reconfiguration command by analyzing the acquired information and running a pre-stored reconfiguration algorithm, wherein the information on spectrum utilization comprises information on utilization of local licensed spectra and borrowed spectra by the wireless communication system and information on spectrum utilization in a primary system, wherein the information on spectrum utilization further comprises a duration of an idle spectrum; and the pre-stored reconfiguration algorithm comprises a loan of spectra by the primary system to a secondary system.
