Definitions
- the present invention relates to a simultaneous conversation system, and in particular, for example, a Push To Talk system and Push.
- PTT Push To Talk
- the PTT system described in Reference 1 and Reference 2 mainly includes a mobile phone (PTT client) used by a user for a call, a group list management server that manages group information, and a user interface. PTT server power is also configured to manage and control calls.
- the user selects a call partner (user or group) on the mobile phone and requests the PTT server to establish a call session.
- the PTT server establishes a session with the specified party in response to a request from the user.
- a group is specified as a partner, the user who is registered in the group is acquired the group list management server power, and a session with the user is established.
- the PTT server holds and manages one floor for one group call session, and assigns and releases a floor to a user according to a floor acquisition / release request from the user. [0007] When a user acquires a floor and another user requests acquisition of the floor, the PTT server rejects the request or the current user acquires the floor and the user Hold the request until it is released.
- the PTT server gives a floor to the requested PTT client in response to a floor acquisition request from each PTT client. Therefore, in order for each PTT client to send data in order, each PTT client holds information about the order, obtains the current status (order), and requests the floor at the time when its order comes. Then you need to have a mechanism. Because of this, conventional
- Another object of the present invention is to allow a certain PTT client to give a floor to another PTT client and request transmission of designated data.
- Still another object of the present invention is to reduce the overhead of the PTT system related to floor control by / J.
- the simultaneous conversation system of the present invention provides a plurality of terminals communicating via a network, and grants and releases a floor as a speaking right to the terminals.
- a server for controlling the floor and the server stores floor control information, which is set by a specific terminal among the terminals, and controls floor granting and releasing.
- the terminal is connected to a session capable of simultaneous conversation.
- a floor control unit that transmits data when a floor grant is received from the floor control unit and terminates data transmission when a floor release is received.
- the terminal of the present invention is based on a session control unit that controls connection to a session in which simultaneous conversation is possible, and floor control information that is information for controlling the granting and releasing of a floor that is a floor.
- the communication unit that receives the information indicating the difference between granting and releasing floors generated in this way, and if the received information is granting floors, send data, and if it is releasing floors And a floor control unit that controls to end data transmission.
- the server of the present invention stores in advance floor control information, which is information for controlling the granting and releasing of a floor as a right to speak !, a floor control information storage unit, and the floor control information And a floor control unit that controls the granting and releasing of the floor to the terminal according to the floor control information stored in the storage unit.
- floor control information which is information for controlling the granting and releasing of a floor as a right to speak !
- a floor control information storage unit and the floor control information
- a floor control unit that controls the granting and releasing of the floor to the terminal according to the floor control information stored in the storage unit.
- the simultaneous conversation method of the present invention is a method in which a terminal is connected to a session that allows simultaneous conversation. Transmitting the information indicating the grant of the floor to the server terminal in accordance with the steps and the floor control information that is the information for controlling the grant and release of the floor that is the floor that is set in advance. And a step of transmitting data when the terminal receives information indicating the provision of a floor.
- the floor is not assigned to the server in response to a request from each terminal.
- the floor is automatically assigned to the terminal based on the order described in the floor control information. This makes it easy for each terminal connected to a session that allows simultaneous conversations to transmit data in order.
- the type of data desired to be acquired can be specified in the floor control information set by the terminal. For this reason, a terminal can give a floor to another terminal and request transmission of designated data.
- the terminal does not require a floor acquisition request or a re-request when a floor acquisition fails.
- the server does not need to handle floor acquisition requests at the server.
- the server can automatically release the floor, the floor release request at the terminal is not necessary. For this reason, the overhead of the simultaneous conversation system related to floor control can be reduced.
