Patent ID: 8713148

Claim:
A transmission terminal, comprising: circuitry configured to: communicate contents data, which includes at least voice data, with a counterpart transmission terminal through a first session, 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, 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 through the first session, and obtain countermeasure data for the predetermined event and to cause the circuitry to transmit the countermeasure data to the counterpart transmission terminal via the transmission management system through the second session, the countermeasure data specifying an action to be taken by the user at the counterpart transmission terminal in response to the predetermined event; and a storage device configured to store a plurality of event data in association with a plurality of countermeasure data specifying an action to be taken in response to a respective event, the countermeasure data for the predetermined event being obtained from the stored plurality of countermeasure data, and the stored plurality of countermeasure data including at least one action to be taken by the user that is based on a loss of voice data communication through the first session.
