Abstract
Abstract A method tests a mobile communication system which includes a base station radio unit (103) for making a line connection with an arbitrary one of mobile stations, a line control unit (104) which is coupled to the base station radio unit, and a pseudo mobile station (101) which is coupled to the line control unit via a monitoring control line (102). The method includes the steps of transmitting a line test instruction from the line control unit to the pseudo mobile station via the monitoring control line, detecting whether or not the pseudo mobile station periodically receives the line test instruction from the line control unit via the monitoring control line, making a line test using a pseudo station identifying information which is assigned to the pseudo mobile station and is peculiar thereto when no line test instruction is periodically received by the pseudo mobile station, and detecting an abnormality in the monitoring control line based on the pseudo station identifying information which is received by the line control unit via the base station radio unit.
