DEVICE AND METHOD FOR CONTROLLING WORKING STATE CHANGE OF SMALL CELL

摘要

Disclosed in the present invention are a device and method for controlling working state change of a small cell and a base station including the device. The device includes: an information acquiring unit configured to acquire interference between a small cell to be controlled and an adjacent small cell and/or load of the small cell to be controlled or load distributed by other small cells and to be borne by the small cell to be controlled; and a state change determination unit configured to determine working state change to be performed by the small cell to be controlled according to the interference and/or load acquired by the information acquiring unit, wherein the working state includes multiple sleep levels from low to high, the sleep degree of the small cell to be controlled in a low sleep level is less than the sleep degree of the small cell to be controlled in a high sleep level, and the working state change is performed among multiple sleep levels.
