Abstract: A mobile object communication system is configured with the assumption that a base station is fixed. Therefore, signal quality becomes unstable if the base station moves freely. Provided is a control apparatus controlling a relay apparatus that is mounted in a mobile object and relays communication between a base station and a communication terminal, including a mobile object information acquiring section that acquires mobile object information indicating a state of the mobile object and a control section that controls the relay apparatus based on the mobile object information. If the movement speed of the mobile object is judged to be less than a predetermined value, the control section may generate a relay control signal indicating that a relay function of the relay apparatus is to be activated.
