ABSTRACT:
A mobile communication system of a cellular type has in each cell a base station (12a-12c) for carrying out bidirectional communication between the base station and a mobile station (11). The base station announces a transmission power of the base station and up link reception power and up link signal quality as information to the mobile station. The mobile station judges whether nor not it is necessary to carry out a hand-over control in accordance with the information and a predetermined hand-over control information. The mobile station judges whether or not it is necessary to carry out said hand-over control in accordance with a down link received signal strength indicator, a down link received signal quality, and the predetermined hand-over control information. The mobile station may judge whether or not it is necessary for the base station to carry out a base transmission power control in accordance with the information and a base maximum transmission power. Furthermore the mobile station may judge whether or not it is necessary for the mobile station to carry out a mobile transmission power control in accordance with the information and a mobile maximum transmission power.
