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.
