1. A simulcasting transmitter control apparatus for use in a base station of a mobile telecommunication system, said base station being provided with a plurality of transmitters each having its own delay characteristic and with a base station control unit providing a set of control data, said control data being usable in simulcasting of a multiplicity of radio frequency signals of the same channel in a reiteration cell area in which outputs of said transmitters are overlapped to each other in a certain area, said simulcasting transmitter control apparatus comprising:

  • means for inputting said control data;

    means for generating a reference clock;

    means for generating a plurality of delayed clocks divided from said reference clock; and

    delay means responsive said control data for delaying a transmission of paging data to a paging receiver by setting a delay time period in accordance with said control data in synchronization with said delayed clocks, so that the simulcasting of said multiplicity of radio frequency signals of the same channel in the reiteration cell area is carried out in said plurality of transmitters.
