Disclosed is a radio communication system provided with an information collection apparatus (300) for collecting: location information which indicates the location of a radio terminal (100a); downlink radio quality information which indicates a measurement result for the radio quality of the downlink between the radio terminal (100a) and a radio base station (200a); and uplink radio quality information which indicates a measurement result for the radio quality of the uplink between the radio terminal (100a) and the radio base station (200a). The radio terminal (100a) measures the radio quality of the downlink when an outgoing call is made therefrom. The radio base station (200a) measures the radio quality of the uplink when the radio terminal (100a) makes an outgoing call.
