Abstract

An integrated accounting system is applied to a network structure which includes a telephone network and a packet network. A packet exchange in the packet network includes a circuit for measuring a communication data quantity within the packet network during a communication between a first terminal which has an advance payment function and is connected to a telephone exchange in the telephone network and a second terminal which is a packet mode terminal connected to the packet exchange. The packet exchange also includes a circuit for sending a control signal to a gate way which couples the telephone exchange and the packet exchange every time a measured communication data quantity reaches a predetermined accounting unit of the telephone network, and a circuit for initially sending the control signal when a call out from the first terminal is detected. The telephone exchange includes a circuit for generating a control signal for every predetermined acocunting unit which is dependent on a duration and distance of a communication within the telephone network, a circuit for sending the control signal generated therein and the control signal received from the gate way to the first terminal, and a circuit for initially sending the control signal when a call out from the first terminal is detected. The first terminal collects an amount of money responsive to the control signal received from the telephone exchange.
