PURPOSE: To obtain transmission quality by measuring the signal strength of the carrier frequency of interference traffic connection within the time, when the carrier frequency of home traffic connection is stopped. CONSTITUTION: A base station BS1 is traffic-connected with a mobile station MS1 by a bidrectional radio channel K1, and the base station BS2 is traffic- connected with the mobile station MS2 by a channel K2 respectively. First, in the home traffic connection, the synthetic reception signal strength (C+I) of the carrier frequency in an instructed radio channel is measured. Then, the signal strength (I) of an interference carrier frequency in the radio channel is measured within the time, when the carrier frequency in the home traffic connection is stopped. Then, the transmission quality is calculated as the quotient (C/I) of the signal strength (C) of the carrier frequency in the home traffic connection and the interference carrier frequency (I). |
