Abstract

PURPOSE:To make coexist a large-cell wide area system and plural small-cell closed area system by making the interference amount of large cells of the wide area system and that of small cells of many closed area systems in the same channel correspond to each other necessarily. CONSTITUTION:Connections between respective wire telephone sets 2 in a building, etc., of a closed area system 1 and between a telephone set 2 and a public telephone network are controlled via a mobile radio communicator 3. The times of use of channel by this system 1 is counted by a used channel counter 10. A summing device 5 provided in a specific closed area system sums up the times of use of the channel of closed systems of the same frequency channel, and the sum is supplied to a counter 10. The number of closed area systems, etc., are controlled so that a large-cell interference amount of wide area systems in the same channel get even with an interference amount of many closed area systems, the interference of many closed area systems is prevented from influencing the wide area systems. In such away, a large-cell wide area system and plural small-cell closed systems are made to be coexistence with each other, and the cell constitution of the both, also, can easily be modified.
