  • Patent number: 10122768
    Abstract: A control system includes controllers controlling a session between communication terminals. Each controller includes a state management unit, first and second updating units, and a receiver. The state management unit manages state information of each terminal indicating a state of connection between the terminal and the controller. When the state of connection between a first terminal and the controller is changed, the first updating unit updates state information of the first terminal. When the state of connection between a second terminal and another controller is changed, the receiver receives, from the other controller, changed state information of the second terminal indicating a state of connection between the second terminal and the other controller after being changed. The second updating unit updates the state information of the second terminal based on the received changed state information. The controller controls the session between the terminals based on the state information.
