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 200, a special call part 206 is switched from a normal mode to an emergency mode, and a mobile station side communication part 206 transmits a radio wave with a transmitted signal of high power (power spectrum density) at the center frequency f0 of a carrier wave. A base station 100 receives the radio wave with the transmitted signal of high power (power spectrum density) at the center frequency f0 of the carrier wave, from the mobile station 200 which output communication for emergency situation. The base station 100 outputs suppression signals for suppressing signal intensity to the other mobile stations. Only the mobile station 200 which transmitted the communication for emergency situation establishes a channel to the base station 100.

Abstract: When emergency communication etc. is sent, it aims at preferentially dealing with the emergency communication etc. by a simple and effective method. It is a communication system in which a base station 100 and a mobile station 200a establish communication for emergency situation, in time of emergency, wherein the mobile station 200a switches an output adjustment from the normal mode to the emergency mode and sends the communication for emergency situation at the largest output possible. The base station 100 receives a strong radio wave from the mobile station 200a which sent the communication for emergency situation. The base station 100 continues to output suppression signals for suppressing signal intensity to the other mobile stations. The other mobile stations are suppressed by the near-far effect, and it becomes impossible for the base station 100 to receive communication except for the communication for emergency situation.
