A transmission system and a participation fee management method for the transmission system are disclosed. The transmission system comprises a transmission management system; and a fee management system. The transmission management system includes a communication control unit, a participation history management unit and a transmission unit. The communication control unit manages a session, which each of a plurality of transmission terminals participates in and leaves freely with the session being a session in which the plurality of transmission terminals transmits and receives content data. The participation history management unit manages history information including a participation date and time and a leaving date and time with the participation date and time indicating a time when each transmission terminal participates in the session and the leaving date and the time indicating a time when each transmission terminal leaves the session. The transmission unit that transmits participation time information for each transmission terminal to the fee management system through a communication network with the participation time information indicating a time period between the participation date and time and the leaving date and time managed by the participation history management unit for each transmission period. The fee management system includes a user management unit, a reception unit, a participation time calculation unit, a participation fee calculation unit and a participation fee summing unit. The user management unit manages user identification information for identifying a user of the transmission terminals and terminal identification information for identifying the transmission terminals used by the user in a manner linked to each other. The reception unit receives the participation time information transmitted from the transmission management system. The participation time calculation unit calculates a total participation time in which the session is made using each of the plurality of transmission terminals based on the received participation time information. The participation fee calculation unit calculates a participation fee for each of the plurality of transmission terminals based on the calculated total participation time with the participation fee being different from each of the plurality of transmission terminals. The participation fee summing unit refers to the user management unit, sums up the participation fee of each transmission terminal indicated by the corresponding terminal identification information for each user identification information, and calculates a total participation fee for each user. |
