Abstract

A transmission terminal communicates contents data with a counterpart transmission terminal through a first session, and transmits management data to a management system through a second session. When a predetermined event that may prevent or interrupt communication with a user at the counterpart terminal is detected, the transmission terminal obtains countermeasure data, and transmits the countermeasure data to the management system through the second session.

Claims

1. A transmission terminal, comprising:

a first data communication unit to communicate contents data with a counterpart transmission terminal through a first session;

a second data communication unit to transmit management data to a transmission management system through a second session, and to keep the second session active at least for a time period between the time when the first session starts and the time when the first session ends;

an event detector to detect a predetermined event that may prevent or interrupt communication between a user at the transmission terminal and a user at the counterpart transmission terminal; and

a countermeasure data generator to obtain countermeasure data for the predetermined event and to cause the second communication unit to transmit the countermeasure data to the transmission management system through the second session, the countermeasure data specifying an action to be taken by the user at the transmission terminal or the user at the counterpart transmission terminal in response to the predetermined event.

2. The transmission terminal of claim 1, further comprising:

a user interface to notify the user at the transmission terminal of the predetermined event detected by the event detector.

3. The transmission terminal of claim 2, further comprising:

a storage device to store event data to be used for identifying the predetermined event, in association with the countermeasure data specifying the action to be taken in response to the predetermined event, wherein

the countermeasure data generator receives event data from the event detector when the predetermined event is detected, and obtains countermeasure data that is stored with respect to the received event data as the countermeasure data to be transmitted.

4. The transmission terminal of claim 3, wherein:

when the action specified by the countermeasure data includes a plurality of different actions each of which can be taken by the user at the transmission terminal or the user at the counterpart transmission terminal,

the user interface requests the user at the transmission terminal to select at least one of the plurality of different actions specified by the countermeasure data, and

the countermeasure data generator obtains countermeasure data specifying the selected one of the plurality of different actions, as the countermeasure data to be transmitted to the transmission management system through the second session.

5. The transmission terminal of claim 1, further comprising:

a converter to convert between voice data and text data, wherein

when the countermeasure data generator determines that the predetermined event detected by the event detector may prevent or interrupt communication of voice data between the transmission terminal and the counterpart transmission terminal, the countermeasure data generator performs at least one of;

converting the voice data generated based on a voice of the user at the transmission terminal to text data using the converter, and generating the countermeasure data based on the converted text data; and

converting text data generated based on a user input received at the transmission terminal to voice data using the converter, and generating the countermeasure data based on the converted voice data.

6. The transmission terminal of claim 1, wherein

the predetermined event that may prevent or interrupt communication between the user at the transmission terminal and the user at the counterpart transmission terminal detected by the event detector includes:

an event that may prevent or interrupt communication of the contents data between the transmission terminal and the counterpart transmission terminal.

7. A transmission system, comprising:

a first transmission terminal; and

a second transmission terminal configured to communicate contents data with the first transmission terminal, wherein

the first transmission terminal includes;

means for communicating contents data with the second transmission terminal through a first session;

means for transmitting management data to a transmission management system through a second session, while keeping the second session active at least for a time period between the time when the first session starts and the time when the first session ends;

means for detecting a predetermined event that may prevent or interrupt communication between a user at the first transmission terminal and a user at the second transmission terminal;

means for obtaining countermeasure data for the predetermined event; and

means for transmitting the countermeasure data to the transmission management system through the second session, the countermeasure data specifying an action to be taken by the user at the first transmission terminal or the user at the second transmission terminal in response to the predetermined event, and the second transmission terminal includes;

means for receiving the countermeasure data obtained by the first transmission terminal from the transmission management system, and

means for outputting information generated based on the countermeasure data to the user at the second transmission terminal.

8. The transmission system of claim 7, further comprising:

the transmission management system to manage a state of communication between the first transmission terminal and the second transmission terminal based on the management data, wherein

the transmission management system includes;

a storage device configured to store time information indicating the time when the first session is established between the first transmission terminal and the second transmission terminal, and to store time information indicating the time when the countermeasure data is received from the first transmission terminal.

9. The transmission system of claim 8, further comprising:

a first relay terminal to relay the contents data to be transmitted between the first transmission terminal and the second transmission terminal through the first session, and wherein

the transmission management system further includes;

a relay terminal selection unit to obtain information regarding a second relay terminal that is previously selected as a candidate relay terminal that is suitable for relaying contents data between the first transmission terminal and the second transmission terminal; and

a selector to obtain the information regarding the second relay terminal when the countermeasure data is received from the first transmission terminal, and to cause the second relay terminal to relay contents data between the first transmission terminal and the second transmission terminal in replace of the first relay terminal.

10. A transmission management method, comprising:

communicating contents data with a counterpart transmission terminal through a first session;

transmitting management data to a transmission management system through a second session, while keeping the second session active at least for a time period between the time when the first session starts and the time when the first session ends;

detecting a predetermined event that may prevent or interrupt communication between a user at the transmission terminal and a user at the counterpart terminal;

obtaining countermeasure data for the predetermined event; and

transmitting the countermeasure data to the transmission management system through the second session, the countermeasure data specifying an action to be taken by the user at the transmission terminal or the user at the counterpart transmission terminal in response to the predetermined event.
