A mobile communication system is disclosed. An area information management server sends area information indicating a communicable peripheral area of a location where a mobile terminal exists, and out-of-service information indicating outside of an accessible region, to the mobile terminal. In the mobile terminal, a generating part generates a moving route and moving projection information. A planning part makes a plan for communication execution indicating a communication term in which the mobile terminal communicates with a base station and an interruption term in which the mobile terminal is outside of the accessible region, based on the moving projection information, and the area information and the out-of-service information. A suspension indicating part indicates suspending or restarting the communication of the mobile terminal and a communication partner before and after the interruption term indicated by the plan. A communication part communicates with the base station in accordance with the plan.
