ABSTRACT:
A propagation delay-propagation loss table is stored in advance in a radio base station, a first area and a second area being set in advance in the propagation delay-propagation loss table, the first area being predicted to contain the relation between the propagation delay and propagation loss when a mobile station is not within the service area of a repeater, while in the second area the effect of the control delay and power gain caused by the repeater upon this first area is taken into consideration. In the radio base station, it is then determined that a mobile station is within the service area of the radio base station when the relation between the propagation loss value that has been reported from the mobile station and the propagation delay that has been calculated is contained within the first area, and it is determined that the mobile station is within the service area of the repeater when the relation is contained within the second area.
