An object is to provide a communication control system, a service management server, a mobile station, a communication control method, and a program, with which the processing load of a network apparatus can be reduced in the case where a great number of communication apparatuses are concentrated. A communication control system of the present invention includes a mobile station concentration prediction unit (10) that predicts an area where a plurality of mobile stations (31) to (34) will be densely concentrated by movement of the plurality of mobile stations (31) to (34), and a communication timing control unit (20) that determines a mobile station to be a communication timing controlled target out of the plurality of mobile stations (31) to (34) predicted to be densely concentrated in the area, and controls the communication timing of the determined mobile station.
