PURPOSE:To allow the center side to recognize the location of each mobile party without special operation or voice response from the mobile party by returning a master station identification signal stored tentatively from a slave station designated when a slave station designation signal designating one slave station among plural slave stations is sent from the center equipment. CONSTITUTION:An identification code of its own station is sent for a short time by a command from the center 100 from master stations 1, 2...n. The center 100 designates the next master station and the other master stations send the identification signal (SID) of their own stations in the same frequency. When all the master stations complete to send the signal by n-station sequential ly, the center 100 sends the identification code of the slave station desired to be recognized simultaneously in the same frequency through the master stations. Each master station enters the reception state immediately and the SID from the designated slave station is received in the same frequency. The received SID is sent to the center through, e.g., a cable and registered. |
