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.

Abstract: Appropriate data communication is realized. A wireless communication device includes a communication unit and a control unit. The communication unit included in the device performs data transmission to a different device via one of frequency channels classified into a plurality of groups that includes a first group and a second group. On the other hand, the control unit detects a reference signal transmitted from the different device via one of the frequency channels belonging to the first group. The control unit further selects one of the frequency channels for the data transmission from the first group or the second group on the basis of a result of detection of the reference signal.

Abstract: [Object] To enable a time before communication by way of a wireless network starts to be further reduced.[Solution] Provided is a terminal device including: an acquisition unit configured to acquire authentication information provided by another terminal device configured to perform mobile communication in a mobile communication network; and an authentication execution unit configured to perform an authentication procedure for connecting to a wireless network different from the mobile communication network by using the authentication information. The authentication information includes information provided by a subscriber identity module of the other terminal device or information generated based on the information. The acquisition unit acquires at least some of the authentication information before the authentication procedure starts.

Abstract: [Object] To favorably make a switch to a direct communication.[Solving Means] 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.

Abstract translation: 有利于切换直接沟通。 解决方案控制装置发送确认请求，以确认是否可以将每个终端直接通信作为直接通信的目标。 每个终端确认直接通信是否可能，并将确认结果发送到控制装置。 控制装置基于从终端发送的确认结果判断是否可以进行直接通信，并且在判断的情况下，向终端侧发送直接通信的切换请求。 因此，可以避免在切换到直接通信时实际上不能建立通信的情况。
