COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To efficiently execute simultaneous notification to each simulcast system with a communication system for executing the notification from an integrater 1 to a plurality of the simulcast systems B1-Bn. SOLUTION: The integrater 1 is provided with a notification request detection means, a timing detection means for detecting notifiable timing for each of a plurality of the simulcast systems corresponding to the detection of a request for the notification, a means for receiving contents of the notification, and a notification transmitting means for transmitting the contents of the notification to each of the simulcast systems at each notifiable timing. Master station devices C1-Cn, D1-Dn are respectively provided with a notification receiving means and a wireless transmission means for the contents of the notification. Slave station devices E1-En are respectively provided with a wireless reception means for the contents of the notification and a notification output means. COPYRIGHT: (C)2007,JPO&INPIT
