Abstract

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.

Claims

1. A radio communication system comprising:

a radio terminal;

a radio base station configured to perform radio communications with the radio terminal; and

an information collection apparatus configured to collect location information indicating a location of the radio terminal, downlink radio quality information indicating a measurement result of a downlink radio quality between the radio terminal and the radio base station, and uplink radio quality information indicating a measurement result of an uplink radio quality between the radio terminal and the radio base station, wherein

the radio terminal measures the downlink radio quality when the radio terminal makes an outgoing call, and

the radio base station measures the uplink radio quality when the radio terminal makes the outgoing call.

2. The radio communication system according to claim 1, wherein

the radio terminal measures the downlink radio quality during call connection processing executed along with the outgoing call, and

the radio base station measures the uplink radio quality during the call connection processing.

3. A radio terminal configured to perform radio communications with a radio base station, comprising:

a call processor configured to make an outgoing call;

a terminal side measurement unit configured to measure a downlink radio quality between the radio terminal and the radio base station, and a location of the radio terminal; and

a terminal side transmitter configured to transmit location information indicating the measured location, and downlink radio quality information indicating the measured downlink radio quality to the radio base station, wherein

the terminal side measurement unit measures the downlink radio quality when the call processor makes the outgoing call.

4. A radio base station configured to perform radio communications with a radio terminal, comprising:

a base station side measurement unit configured to measure an uplink radio quality between the radio base station and the radio terminal;

a base station side receiver configured to receive, from the radio terminal, location information indicating a location of the radio terminal, and downlink radio quality information indicating a downlink radio quality measured by the radio terminal; and

a base station side transmitter configured to transmit uplink radio quality information indicating the uplink radio quality measured by the base station side measurement unit, the location information, and the downlink radio quality information to an information collection apparatus, wherein the base station side measurement unit measures the uplink radio quality when the radio terminal makes an outgoing call.

5. An information collection method comprising:

making an outgoing call by a radio terminal;

measuring a downlink radio quality between the radio terminal and a radio base station by the radio terminal when the radio terminal makes the outgoing call;

measuring an uplink radio quality between the radio base station and the radio terminal by the radio base station when the radio terminal makes the outgoing call; and

collecting by an information collection apparatus, location information indicating a location of the radio terminal, downlink radio quality information indicating a measurement result of the downlink radio quality, and uplink radio quality information indicating a measurement result of the uplink radio quality.
