Abstract

Abstract A mobile communication system and mobile communication method are capable of avoiding call-interruption while calling attention of the user who calls to be moved before entering transmission-stop zone. In the mobile communication method, it causes a base station ID to be received while retrieving all frequencies (step 11), thus judging whether or not there exists base station ID of "transmission-stop" instruction (step 12). When there is the base station ID of the "transmission-stop" instruction, it is judged that a mobile station exists in a transmission control zone, it comes into a state in which transmission is stopped, before coming into reception state (step 17). While when there is no the base station ID of the "transmission-stop" instruction, it is judged that a mobile station exists out of a transmission control zone (step 13), thus being selected a transmission destination (step 14). There is judged whether or not warning information is incorporated in base station ID of the transmission destination base station (step 15). When the warning information exists, the warning information/warning sound is generated (step 18), followed by shifting to normal operation (step 16). While when no warning information exists in the base station ID of the transmission destination, transmission is started to the transmission destination base station while shifting to the normal operation (step 16).
