Abstract: An emergency message communication method which enables communication by disregarding channel shortages in emergency message communication. Even if no talking channel is empty or if voice communication is impossible due to system power capacity saturation for a mobile station transmitting an emergency call, the present invention enables emergency message communication that connects the emergency call preferentially by temporarily stopping traffic channel communication for other mobile stations and reducing power use with a lower voice rate.
