Abstract
The present disclosure provides a method for radio frequency fingerprint database creation, a method for radio frequency fingerprint database application, a device, a centralized processing device and a base station. During creating a radio frequency fingerprint database, neighbor cell information statistics is performed on each of a plurality of neighbor cells of the cell in each of the plurality of divided grids, and an effective radio frequency fingerprint database corresponding to the cell is generated according to a result of the dividing and a result of the neighbor cell information statistics.
