Abstract
In a communication system for a plurality of terminals, a terminal control unit is connected between a call control unit and the terminals. The terminal control unit is associated with a memory unit having a group supervisory table for storing a relationship between group numbers and the terminals belonging thereto for message broadcasting. When a destination call message is supplied from the call control unit to the terminal control unit, a group number is analyzed from the destination call message. Then, a number of the terminals belonging to the analyzed group number are selected in accordance with the group supervisory table, and message broadcasting is performed upon the selected terminals.
