PURPOSE:To compose a call group to give the same call channel to plural groups by providing a function to arbitrarily set the combination of the call groups for each radio equipment GROUP beforehand and executing a management by means of a central control unit. CONSTITUTION:The group constitution of radio equipment for a group call is made, a GROUP and a group are provided, and the function to arbitrarily set the combination of the call groups made into a unit for executing the group call by an input to the radio equipment for each radio equipment GROUP is provided to each radio equipment. When radio equipment 1-1-1-1 to belong to a GROUP 1 and a group 1 executes calls to the radio equipment GROUP of the GROUP 1 and a group 2 and the radio equipment GROUP of a GROUP 3 and a group 3 by using a call between arbitrary groups, the calls are executed through a central processing unit 4. Namely, the unit 4 manages group combination information for realizing the call between the arbitrary groups on a memory table, and the unit 4 executes the management in re-reading a preset number sent from the radio equipment into a group number. Thus, the call group to give the same channel to plural groups can be composed. |
