Abstract

To transmit content data to a second terminal while transmitting content data to a first terminal, a management system includes a receiver configured to receive a request sent from a first terminal for establishing a first session between the first terminal and a second terminal, and a session controller configured to send the request for establishing the first session to the second terminal while a second session, other than the first session, is underway between the first terminal and a third terminal, upon receiving the request for establishing the first session.

Claims

1. A management system comprising:

a receiver configured to receive a request sent from a first terminal for establishing a first session between the first terminal and a second terminal; and

a session controller configured to send the request for establishing the first session to the second terminal while a second session, other than the first session, is underway between the first terminal and a third terminal, upon receiving the request for establishing the first session.

2. The management system according to claim 1,

wherein the session controller determines whether to send the request for establishing the first session to the second terminal, based on information indicating whether the first terminal is capable of establishing the first session and the second session at the same time.

3. The management system according to claim 1,

wherein, upon receiving the request for establishing the first session while the second terminal is in the second session, the session controller sends the request for establishing the first session to the second terminal after excluding the second terminal from the second session.

4. The management system according to claim 1,

wherein the session controller halts distribution of sound data transmitted from the first terminal in the second session in an event of establishing the first session while the second session is underway.

5. The management system according to claim 4,

wherein the session controller informs the third terminal, at the time of halting the distribution of the sound data, that the distribution of sound data is halted.

6. A transmission terminal comprising:

a session controller configured to change a quality of transmission of content data in a second session, in an event of establishing a first session with a first terminal while the second session is underway with a second terminal; and

a communicator configured to perform the transmission of content data in the second session in accordance with the changed quality.

7. The transmission terminal according to claim 6,

wherein the first session is for communicating with the first terminal,

wherein the second session is for distributing content data including sound data to the second terminal, and

wherein the session controller halts the distribution of sound data through the communicator, so as to change the quality of transmission of content data in the second session.

8. The transmission terminal according to claim 7,

wherein the session controller records content data in an event that the first session is not able to be established, and

wherein the communicator sends the recorded content data to the first terminal.

9. The transmission terminal according to claim 6, the transmission terminal further comprising:

a communication band acquirer configured to acquire information concerning a communication band provided for communication with a relay device that relays content data in the first session and the second session; and

a quality determiner configured to determine the quality of transmission in the first session and the second session, based on the acquired information concerning the communication band,

wherein the session controller changes the quality of transmission of content data in the second session, based on the determined quality of transmission.

10. The transmission terminal according to claim 9,

wherein the quality determiner determines the quality of transmission of content data based on a rate assigned to the transmission of content data or a minimum communication band corresponding to the transmission of content data.

11. A method for transmission management implemented by a management system, the method including:

receiving a request sent from a first terminal for establishing a first session between the first terminal and a second terminal; and

sending the request for establishing the first session to the second terminal, in an event that the receiver receives the request for establishing the first session while a second session, other than the first session, is underway between the first terminal and a third terminal.
