Abstract:
1. A mobile communication control method in which a mobile station transmits data using at least one currently transmitting base station and also sets a link with base stations forming an active set of base stations, comprising: measuring a received signal quality of a pilot signal transmitted from each of said active set of base stations; determining at least one transmitting base station from among the active set of base stations in accordance with the measured results, said determining further comprises enabling for transmission all of the active set base stations depending on a state of transmission power value from said at least one currently transmitting base station; transmitting a dedicated control signal to said mobile station from said active set of base stations; transmitting a dedicated data signal to said mobile station from said at least one currently transmitting base station; estimating a transmission power value of the dedicated control signal transmitted by said active set of base stations, and making each of the active set of base stations a transmitting base station when an estimated value of the transmission power value of the dedicated control signal transmitted by the active set of base stations other than said at least one currently transmitting base station is greater than or equal to a predetermined threshold value for the estimated value of transmission power value of the dedicated control signal transmitted by said at least one currently transmitting base station.
