Communication control device, communication system, and communication control method
First Claim
1. A communication control device configured to control data communication between a plurality of terminals over a communication network, the communication control device comprising:
- processing circuitry configured to;
acquire pieces of status information, each piece of status information representing an operating state of a corresponding terminal of the plurality of terminals;
acquire pieces of reception information, each piece of reception information representing a state of the communication network when a corresponding terminal of the plurality of terminals has received data;
determine whether communication is one-way communication or two-way communication based on a combination of the pieces of status information of multiple terminals that participate in a same communication; and
when the communication is determined to be one-way communication, determine a terminal, participating in the one-way communication, that is leading the one-way communication; and
control a quality of data that each terminal transmits or receives in the communication based on the type of communication and the pieces of reception information, whereineach piece of status information includes an on/off state of a corresponding microphone that inputs voice,when the combination of the pieces of status information of the multiple terminals that participate in the same communication indicates that a microphone of only one terminal is in an on state and microphones of the other terminals are all in an off state, the processing circuitry determines that the communication is one-way communication and that the terminal whose microphone is in an on state is leading the one-way communication, andwhen the communication is determined to be one-way communication, the processing circuitry controls the quality of data transmitted by the terminal leading the one-way communication to be higher than a quality of data transmitted or received by terminals subordinate in the one-way communication.

Abstract
A communication control device is configured to control data communication between terminals using a communication network. The communication control device include: a status-information acquiring unit configured to acquire respective pieces of status information which represent operating states of the terminals; a reception-information acquiring unit configured to acquire respective pieces of reception information which represent states of the communication network when the terminals have received data; a communication determining unit configured to determine a type of communication on the basis of a combination of pieces of status information of multiple terminals that participate in the same communication; and a quality control unit configured to control quality of data that each terminal transmits or receives on the basis of the determined type of communication and the acquired reception information.
