Abstract: In an accounting system for a multimedia communications system, an additional information storage unit stores additional information to be supplied to subscriber terminals in the multimedia communications system by one or a plurality of additional information suppliers. An additional information adding unit adds the additional information to communication information transmitted between subscriber terminals communicating with each other. A measurement unit measures a degree of supply of the additional information supplied to at least one of the subscriber terminals communicating with each other. A database unit stores accounting information used to calculate a fee for a communication between the subscriber terminals communicating with each other. A control unit calculates the fee for the communication between the subscriber terminals communicating with each other on the basis of the accounting information and the degree of supply of the additional information measured by the measurement unit.
