Method and apparatus for adjusting spectrum resources

The present invention provides a method and apparatus for adjusting spectrum resources. The method comprises: acquiring the number of users activated by a first standard network supported by a base station; acquiring a PRB utilization rate of a second standard network supported by the base station; and adjusting, according to the number of the users and/or the PRB utilization rate, spectrum resources of the first standard network and the second standard network. The present invention solves the problem of failure in dynamic scheduling of the number of 2G/3G narrow-band signal carriers and an LTE bandwidth in the related art, and improves the spectrum utilization rate.
