  • Patent number: 10820179
    Abstract: A control apparatus transmits a confirmation request to confirm whether a direct communication is possible to each terminal as a target of the direct communication. Each terminal confirms whether the direct communication is possible and transmits the confirmation result to the control apparatus. The control apparatus judges whether the direct communication is possible based on the confirmation result transmitted from the terminal and when judging as possible, transmits a switch request for the direct communication to the terminal side. Consequently, a situation where a communication cannot actually be established when switching to the direct communication can be avoided.
