Abstract
When a mobile station registered at a closed-type femtocell base station is in a connection state in a cell area covered by the femtocell base station, the transfer power of the femtocell base station for a cell identification signal is adjusted according to one scale estimating the receiving quality of the cell identification signal at the mobile station. When no mobile station is located in the cell area covered by the femtocell base station, the cell identification signal is sent with the minimum transmission power necessary for a mobile station to make a call in the cell area to reduce the power consumption of the femtocell base station and also to reduce interference with other macrocell base stations and other femtocell base stations.
