Wireless communication control method, wireless communication system, and radio control station

A wireless communication system comprising:

• a plurality of mobile stations;
• a base station which performs wireless communication with a mobile station in a cell using a resource assigned based on a predetermined scheduling method;
• and
• a radio control station which controls use of the resource in wireless communication for said base station,
• said mobile station comprising
• a first data transmission unit which transmits data to said base station using a first resource assigned based on a first scheduling method and
• a second data transmission unit which transmits data to said base station using a second resource which is assigned based on a second scheduling method and is not used in said first data transmission unit, and
• said radio control station comprising a resource control unit which instructs said base station to regulate use of the first resource in accordance with a second resource amount (Pu) available as the second resource, and a second resource usage (Up) as a ratio of an amount of a resource used in said second data transmission unit to the second resource amount,
• wherein said resource control unit comprises:
• means for calculating an unused amount of the resource at said base station by subtracting an in-use amount of the resource at said base station reported therefrom from a target value of the resource at said base station notified thereto in advance;
• means for calculating a total reception power from said mobile station that transmits the data to said base station in the above second-recited step of transmitting under the control of a cell forming said base station, by multiplying, by the in-use amount of the resource, a ratio received scheduled enhanced dedicated channel (E-DCH) power share, reported from the base station, of the amount of the resource used in said second data transmission unit versus the in-use amount of the resource;
• means for calculating an amount of the resource available as said second resource out of the entire amount of the resources of said base station by adding said total reception power to said unused amount of the resource;
• and
• means for calculating said second resource usage by dividing said total reception power by said amount of the resource available as said second resource.
