<P>PROBLEM TO BE SOLVED: To provide a method for suppressing transmission power necessary for the transmission of an E-AGCH (Enhanced Dedicated Channel-Absolute Grant Channel), and a method for efficiently using limited resources of transmission power used in a radio base station device. <P>SOLUTION: In a mobile communication system with a radio base station which has a transmission power control function of the E-AGCH when an EUDCH (Enhanced Uplink Dedicated Channel) service is offered to a radio terminal, the radio base station is provided with: a transmission route distance measuring means by which the radio terminals measure distances of the transmission routes from the radio base station; a maximum transmission distance decision means which decides the longest maximum transmission route distance out of the transmission route distances of the respective radio terminals measured by the transmission route distance measuring means; and a transmission power calculation means which calculates necessary minimum transmission power from a cell radius of the radio station and the maximum transmission route distance. <P>COPYRIGHT: (C)2011,JPO&INPIT |
