FREQUENCY ALLOCATION METHOD AND DEVICE FOR UNAUTHORIZED FREQUENCY BAND

摘要

Disclosed are a frequency allocation method and device for an unauthorized frequency band. The method comprises: a controller acquires a business load status of a plurality of macro base stations having similar coverage ranges, and generates, based on the business load status, allocation information about an unauthorized frequency band, so as to mutually exclusively allocate the unauthorized frequency band to the plurality of macro base stations, wherein the plurality of macro base stations is operated by different operators; the macro base stations receive the allocation information about the unauthorized frequency band from the controller, so as to determine the unauthorized frequency band monopolized by the macro base stations from an unauthorized frequency band resource, and the macro base stations generate indicative information about the monopolized unauthorized frequency band; and a small base station receives the indicative information about the monopolized unauthorized frequency band from the macro base stations, detects the state of the unauthorized frequency band monopolized by the macro base stations, and dynamically accesses, according to a detecting result, a specific unauthorized frequency band in the unauthorized frequency band monopolized by the macro base stations.
