Mobile communication system and method for controlling receiving quality

A receiving quality control method for a mobile communication system having a plurality of base stations, a network control station conceptually located above said plurality of base stations and mobile stations receiving signals from said plurality of base stations, the method being characterized in that:

• said mobile station notifies quality control means, which is coupled to said network control station and communicates with the mobile stations, of a downlink receiving quality desired by the mobile station and the location of the mobile station,
• said quality control means determines to which base stations the mobile station is to be connected in order to satisfy the downlink receiving quality by the mobile station and notifies the network control station of the desired base stations to which the mobile station is to be connected,
• said network control station transmits a duplicated information signal to said desired base stations in order to allow a mobile station to simultaneously communicate with at least two base stations, and
• said mobile station further receives and synthesizes signals transmitted by the plurality of base stations to control the downlink receiving quality.

A computer-readable medium having thereon computer-executable instructions representing a receiving quality control program for a mobile communication system, the mobile communication system having a plurality of base stations, a network control station conceptually located above said plurality of base stations and mobile stations receiving signals from said plurality of base stations, the computer-executable instructions being characterized by allowing execution of steps of:

• in said mobile station notifying quality control means, which is coupled to said network control station and communicates with the mobile stations, of a downlink receiving quality desired by the mobile stations and the location of the mobile station;
• in said quality control means determining to which base stations the mobile station is to be connected in order to satisfy the downlink receiving quality desired by the mobile station and notifying said network control station of the desired base stations to which the mobile station is to be connected;
• in said network control station transmitting a duplicated information signal to said desired base stations in order to allow a mobile station to simultaneously communicate with at least base stations;
• and
• in said mobile station further receiving and synthesizing signals transmitted by the plurality of base stations to control the downlink receiving quality.
