Provided is a voice communication system that notifies a terminal device of transmission restriction information when the number of received voice signals reaches a predetermined number. A server device continuously counts the number of simultaneously received voice signals. A first terminal device transmits, to the server device, a voice signal with identification information of a second terminal device. The server device transfers, to the second terminal device, the voice signal transmitted from the first terminal device. However, when the number of simultaneous receptions of the voice signals reaches a predetermined restriction value, the server device transfers, to the second terminal device, the received voice signal with transmission restriction information attached thereto. The second terminal device does not transmit a voice signal, even if a user performs a transmission operation, during reception of the voice signal with the attached transmission restriction information.

Voice communication system, voice communication method, and voice communication program

[Problem] Provided is a relaying device that can track and record a communicated voice of a specific communication terminal using a mixing function of the relaying device. [Solution] When a communication terminal has sent a call packet to call another at least one communication terminal, a communication session in which this communication terminal that has made a call and a communication terminal that has been called are participating terminals is established. In the communication session, voice communication is relayed by transferring a voice signal which is transmitted from the participating terminals to another at least one communication terminal. A virtual device is registered as a participating terminal of the communication session and the voice signal which is transmitted from the communication session to the virtual device is recorded in the relaying device.

Relaying device and monitoring method of voice communication

[Problem] To enable priority communication using a terminal device by setting a particular mode in the terminal device by user operation and thereby increasing a priority of the terminal device. [Solution] A server as a relay device, in forming a new session, compares the priority of an existing session with the priority of the new session, and, if the priority of the new session is higher than the priority of the existing session, removes a competing terminal device participating in the existing session from the existing session and makes the competing terminal device participate in the new session. Further, upon reception of a specific calling voice signal specifying the terminal device participating in the existing session as a communication partner from the terminal device set to a particular mode, the relaying device removes the terminal device participating in the existing session from the existing session and makes the terminal device participate in a session to be formed by the specific calling voice signal regardless of the priority of the session.

Voice communication system, relaying device, terminal device, session management method and non-transitory computer-readable recording medium

[Problem] To provide am audio communication system configured such that a relaying device and terminal devices are connected via a communication network, and communication between terminal devices is managed on the relying device side on the basis of the priority of communications. [Solution] The relaying device is provided with a network communication unit, a control unit, and a priority information storage unit. A network communication unit communicates with a plurality of terminal devices via a communication network. A control unit transfers audio signals between terminal devices participating in a communication session. When a calling audio signal specifying a terminal device participating in the existing communication session as a communication partner is received, and the priority of the new communication session is higher than the existing communication session, the control unit causes the terminal device participating in the existing communication session to participate in the new communication session. The terminal devices transmit, to the relaying device, the audio signals to which transferring destination information indicating the transferring information of the audio signal has been applied.

Relaying device, audio communication system, and relaying method

[Problem] To provide an audio communication system in which a relaying device is connected to communication devices via a communication network, the communication devices being terminal devices, and the current location of each terminal device is managed by the relaying device. [Solution] this relaying device is provided with a network communication unit, a control unit, and a storage unit. The control unit divides the communication area of a communication network into a plurality of partial communication areas and stores, in the storage unit, location information indicating which partial communication area each terminal device is in. Upon a partial communication area specifying call from a calling terminal device, the calling terminal device being one of the aforementioned terminal devices, the control unit establishes a communication session in which the calling terminal device and terminal devices in the specified partial communication area participate, and audio signals received from terminal devices participating in the communication session are transferred by the control unit to the other terminal devices participating in the communication session.

Relaying device, audio communication system, and relaying method of audio signal

[Problem] To provide an audio communication system in which a relaying device is connected to terminal devices via a communication network and said terminal devices communicate with each other on the basis of assignments for said terminal devices. [Solution] This relaying device is provided with a network communication unit, a storage unit, and a control unit. The network communication unit is connected to a communication network and communicates with a plurality of terminal devices over said communication network. The storage device assigns each terminal device to one of a plurality of subsystems and stores, for each terminal device, the assigned subsystem and identifying information. When an audio signal is received from a given terminal device, the control unit identifies the subsystem to which said terminal device is assigned from originating-terminal-device information attached to the audio signal and forwards the audio signal to another terminal device assigned to the identified subsystem. The terminal devices transmit audio signals to the relaying device, each of said audio signals having forwarding-destination information that specifies the forwarding destination for said audio signal attached thereto.

A relaying device is provided, which can mediate by using communications of a wireless apparatus without clipping off the beginning of verbal communication. The relaying device includes: a network interface that receives an audio signal as a group of packet trains via a network; a wireless apparatus interface to which a wireless apparatus is connected; a voice buffer that temporarily stores the audio signal; and a control unit that starts temporarily storing the audio signal in the voice buffer and requests the wireless apparatus to reserve a channel, when a leading packet of the group of packet trains is received, and that reads the temporarily stored audio signal from the voice buffer and transfers the audio signal to the wireless apparatus, after receiving from the wireless apparatus a reply indicating that a channel has been reserved.
