ABSTRACT:
In a cell management method and apparatus which can prevent a call loss generated in association with an increase of cell usage rate independent of a protection frequency bandwidth, cell usage rates of operating cells (at frequency Fo) are acquired. Narrower nonoperating cells (at frequency Fo) of the operating cell in which the cell usage rate indicates a high-load state are rendered an addition candidate and the operating cell is rendered a deletion candidate. A broader nonoperating cell (at frequency Fo) of the operating cell in which the cell usage rate indicates a low-load state is rendered an addition candidate, and the operating cell and other narrower operating cells belonging to the nonoperating cell are rendered deletion candidate. From among the nonoperating cells that are the addition candidate and the operating cells that are the deletion candidates, a nonoperating cell(s) to be switched over to an operating cell(s) and an operating cell(s) to be switched over to a nonoperating cell(s) is determined.
