Abstract
It aims at preferentially dealing with emergency communication etc. by a simple and effective method when emergency communication etc. is initiated. In emergency situation, at a mobile station, a special call partis switched from a normal mode to an emergency mode, and a mobile station side communication parttransmits a radio wave with a transmitted signal of high power (power spectrum density) at the center frequency fof a carrier wave. A base stationreceives the radio wave with the transmitted signal of high power (power spectrum density) at the center frequency fof the carrier wave, from the mobile stationwhich output communication for emergency situation. The base stationoutputs suppression signals for suppressing signal intensity to the other mobile stations. Only the mobile stationwhich transmitted the communication for emergency situation establishes a channel to the base station
