Spectrum demand forecasting method and device

The invention provides a spectrum demand forecasting method and device. The method comprises the following steps: forecasting a user's service volume in a set time period in a region, and transmission rates of the service in different types of districts in the service volume in the region; forecasting the macro base station number, micro base station number and corresponding service carrying capacity thereof in different types of districts in the region according to the transmission rate, preset macro base station total number, the allocation proportion of the macro base station in different types of districts of the region; forecasting the macro base station number, micro base station number and corresponding service carrying capacity thereof in different types of districts of the region according to the transmission rate of service in different types of districts, and forecasting the using frequency spectrum of the user in the future of the region. Through the adoption of the method and device provided by the embodiment of the invention, a technical problem that the accuracy of the network spectrum demand predicting in the prior art is not high, so that the spectrum resource of the network cannot be configured reasonably is solved.
