Transmission terminal, communication system, and computer-readable storage medium

摘要

A transmission terminal is connected to a management device via a network. The transmission terminal includes an acquisition unit configured to acquire a communication state of another transmission terminal from the management device; a selection accepting unit configured to accept a selection of the another transmission terminal from a user to participate in an established session that has been already established for the another transmission terminal; a participation determination unit configured to determine that it is not possible to participate in the established session when the communication state of the another transmission terminal whose selection has been accepted indicates participation restriction; and a communication unit configured not to transmit a participation request to the management device when it is determined that the participation is not possible.

1. A transmission terminal connected to a management device via a network, the transmission terminal comprising:
processing circuitry configured to
transmit, to the management device, a request for retrieving communication state information of one of a first transmission terminal and a second transmission terminal, wherein the first and second transmission terminals are different from the transmission terminal, and the first terminal is in an established communication system session with the second terminal, which is indicated by the communication state information,acquire the communication state information of the one of the first transmission terminal and the second transmission terminal from the management device;determine that it is not allowable to participate in the established session when the communication state information of the one of the first transmission terminal and the second transmission terminal indicates a participation restriction; anddetermine to not transmit a participation request to the management device when it is determined that the participation is not allowable.
