A communication control method is a method in which a neighboring cell #1 supplements a coverage of an OFF target cell #2 by increasing transmission power of the neighboring cell #1, when setting the OFF target cell #2 to an OFF state. The communication control method comprises: a step A of informing, by a UE 100 connected to the OFF target cell #2, the OFF target cell #2 of neighboring cell received power that is received power of a radio signal from the neighboring cell #1; and a step B of deciding, by a server 400 that acquires the neighboring cell received power via the OFF target cell #2, on the basis of the acquired neighboring cell received power, an amount of increase in transmission power of the neighboring cell #1.
