ABSTRACT:
In a mobile terminal communication method, when a zone in which a mobile terminal is positioned becomes in a congestion state, a calling channel having high emergency can be secured. A connection priority rank is given to each mobile terminal. When an area in which a calling mobile terminal is positioned is in the congestion state, the number of currently-used calling channels in the same connection priority rank as that of the mobile terminal is compared with the number of the calling channels set to the rank. Depending on its result, the call is disconnected or another mobile terminal in a low connection priority rank is handed off to another area.
