Title:
FREQUENCY MANAGEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/131142
Kind Code:
A1
Abstract:
A frequency management device according to a mode of embodiment of the present invention allocates frequency bands to be used individually by each of a plurality of radio networks sharing a frequency band, and is provided with: a storage unit which stores frequency spectrum unit information indicating a unit which forms the shared frequency band, and initial spectrum quantity information of frequency spectra used by each of the plurality of radio networks; a receiving unit which receives, via a shared control unit belonging to the plurality of radio networks, required spectrum quantity information indicating a necessary frequency spectrum quantity; an allocation calculating unit which calculates a relative spectrum quantity to be allocated to each of the plurality of radio networks, on the basis of the initial spectrum quantity information and the required spectrum quantity information; and a spectrum calculating unit which calculates an allocated spectrum quantity to be allocated to each of the plurality of radio networks, on the basis of the relative spectrum quantity and the frequency spectrum unit information corresponding to each of the plurality of networks.
