Abstract
A method and apparatus for controlling a transmission signal for a disaster scene communication system. The method includes determining a type of a transmission message transmitted to a mobile terminal device by a control terminal device of the disaster scene communication system, determining a criticality level of the transmission message corresponding to the type of the transmission message, determining an initial distance between the control terminal device and the mobile terminal device by checking initial location information of the mobile terminal device, setting an initial transmission power in consideration of the criticality level of the transmission message corresponding to the type of the transmission message and the initial distance between the mobile terminal device and the control terminal device, and controlling a current transmission power based on the initial transmission power.
