PURPOSE:To attain the channel switching test between two arbitrary radio base stations, by remote-controlling a virtual mobile station for line test provided to a radio base station from a monitoring and controlling console. CONSTITUTION:When a line test registration and an operating line reservation are performed from the control of a monitoring and controlling console 6, the line connection is done between fixed telephone sets connected to a car telephone exchange station 7 and a line test virtual mobile station in a monitor controller 3 of a station to be monitored to confirm the possible call. In this state, when a channel switching test command is transmitted from the console 6, a monitor controller 5 gives a command to reduce the output level of the virtual mobile station to the device 3 and transmits a channel switching command so as to attain channel switching to a radio base station 8' to be switched registered in advance. When a connection controller 2 discriminats the reduction in the level of the virtual mobile station for line test, a level decreasing signal is transmitted to a radio line controlling station 4. The controlling station 4 receives the level information from all the radio base stations to check whether or not the maximum level information address is coincident with the switched address. |
