In the radio terminal 3-n of the radio system, when performing transmission or reception, logging data is accumulated and stored in an internal memory. The logging data contains a location, a date and time, an RSSI (Received Signal Strength Indicator) value and a BER (Bit Error Rate) value. The base station radio apparatus 1 collects and analyzes the logging data of the radio terminal 3-n to grasp a daily intra-area speech channel quality. <P>COPYRIGHT: (C)2010,JPO&INPIT
