Claim:
A mobile communication system, comprising: a base station; and a first mobile terminal which transmits state information of the first mobile terminal to the base station, wherein the base station transmits the state information to a second mobile terminal to inform the second mobile terminal that a call was released based on a low reception signal strength of the first mobile terminal, wherein the second mobile terminal monitors the reception signal strength of first mobile terminal after the call release and performs an automatic call connection operation to re-establish the call when the signal strength of the first mobile terminal exceeds a predetermined level, wherein one of the first mobile terminal or second mobile terminal is the call originating terminal and the other of the first mobile terminal or second mobile terminal is the call receiving terminal, and wherein the first and second mobile terminals are subscriber terminals and wherein the call is re-established between the first and second mobile terminals through a signal path that does not pass through an intervening mobile subscriber terminal or a repeating mobile subscriber terminal.
