Abstract:
1. A cell management method comprising: a first step of acquiring a cell usage rate of at least one operating cell; a second step of allocating, when the acquired cell usage rate is in a high-load state, a narrower nonoperating cell, among the operating cell in the high-load state at a common frequency as an addition candidate and allocating the operating cell in the high-load state as a deletion candidate, or a second step of allocating, when the acquired cell usage rate is in a low-load state, a broader nonoperating cell, among the operating cell in the low-load state at the common frequency, as the addition candidate, another narrower operating cell belonging to the broader nonoperating cell as the deletion candidate, and the operating cell in the low-load state as the deletion candidate; and a third step of determining, from among the nonoperating cells of the addition candidate and the operating cells of the deletion candidate, a nonoperating cell to be switched over to the operating cell and an operating cell to be switched over to the nonoperating cell, within an upper limit number of operating cells.
