Abstract
Abstract A total transmitting power of a base station calculated in a total transmitting power monitor is compared with a predetermined value in a comparator. When the total transmitting power is detected to exceed a first predetermined value, the transmitting power of a pilot signal transmitted by the base station is decreased by a pilot signal transmitting power controller. As a result, a forward channel can be assigned the transmitting power even when the number of mobile stations increases. Further, a priority for disconnection of the channel may be discriminated depending upon a characteristic of the mobile station, and the channel may be disconnected based on the comparing step and the discriminating priority step.
