Abstract

PURPOSE:To enable to deliver the emergency signal to the base station with minimum transmission wait, by providing the time slot to deliver the emergency signal between time slots. CONSTITUTION:The times T1' to Tn' are specifically determined for each mobile station 2, and the time of timer 6 is set to each mobile station 2 so that the specific time slots t1' to tn' assigned respectively can be formed. Further, the time slots t1' to tn' are formed by clipping the time slot to so that the base station can receive the emergency signal FE. Further, emergency happens between the time slots t1' at the mobile station 2, then the mobile station 2 transmits the emergency signal FE through the radio set 8 from the emergency communication controller 10. The base station 1 receives the emergancy signal FE at the time slot to and the emergency communication controller 11 recognizes the emergency. Further, if it is necessary to confirm the mobile station 2, the specific number is also included.
