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.

Claims

1. An integrated accounting system for a network structure which includes a telephone network and a packet network, said integrated accounting system comprising:

a telephone exchange within the telephone network;

a packet exchange within the packet network;

a gate way coupling said telephone exchange and said packet exchange;

a first terminal having an advance payment function and coupled to said telephone exchange, said first terminal including collecting means for collecting an amount of money;

a second terminal coupled to said packet exchange, said second terminal being a packet mode terminal;

said packet exchange including means for measuring a communication data quantity within the packet network during a communication between said first and second terminals, means for sending a control signal to said gate way every time a measured communication data quantity reaches a predetermined accounting unit of the telephone network, and means for initially sending the control signal when a call out from said first terminal is detected;

said telephone exchange including means for generating a control signal for every said predetermined accounting unit which is dependent on a duration and distance of a communication within the telephone network, means for sending the control signal generated therein and the control signal received from said gate way to said first terminal, and means for initially sending the control signal when a call out from said first terminal is detected; and

said collecting means of said first terminal collecting the amount of money responsive to the control signal received from said telephone exchange.

2. The integrated accounting system as claimed in claim 1 wherein said collecting means of said first terminal collects the amount of money by collecting coins inserted into said first terminal.

3. The integrated accounting system as claimed in claim 1 wherein said collecting means of said first terminal collects the amount of money by subtracting units from a card which has units equivalent to an arbitrary amount of money recorded thereon.

4. The integrated accounting system as claimed in claim 3 wherein said card is selected from a group which includes at least an integrated circuit card and a magnetic card.

5. The integrated accounting system as claimed in claim 1 wherein said collecting means of said first terminal collects the amount of money by collecting coins inserted into said first terminal and/or by subtracting units from a card which has units equivalent to an arbitrary amount of money recorded thereon.

6. The integrated accounting system as claimed in claim 1 wherein said control signal is transmitted on a signal line which is independent of a data line on which data is transmitted.

7. The integrated accounting system as claimed in claim 1 wherein said control signal is transmitted on a data line together with data.

8. The integrated accounting system as claimed in claim 1 wherein said means of said packet exchange for initially sending the control signal detects whether or not the call out is received from a terminal having an advance payment function and sends the control signal to said gate way only when the call out is received from the terminal having the advance payment function.

9. The integrated accounting system as claimed in claim 1 wherein said means of said packet exchange for measuring the communication data quantity counts a number of packets transmitted and received in the packet network.

10. The integrated accounting system as claimed in claim 9 wherein said means of said packet exchange for sending the control signal sends the control signal to said gate way when a counted number of packets reaches a predetermined number which corresponds to one predetermined accounting unit of the telephone network.

11. The integrated accounting system as claimed in claim 10 wherein said means of said packet exchange for sending the control signal further includes means for looking up a table which stores said predetermined number for a plurality of kinds of packets having mutually different number of bytes.

12. The integrated accounting system as claimed in claim 1 wherein said means of said telephone exchange for initially sending the control signal detects whether or not the call out is received from a terminal having an advance payment function and sends the control signal to said first terminal only when the call out is received from the terminal having the advance payment function.

13. The integrated accounting system as claimed in claim 1 wherein said means of said telephone exchange for generating the control signal detects a duration of the communication within the telephone network.

14. The integrated accounting system as claimed in claim 13 wherein said means of said telephone exchange for sending the control signal sends the control signal to said first terminal when a detected duration reaches a predetermined time which corresponds to one predetermined accounting unit of the telephone network.

15. The integrated accounting system as claimed in claim 14 wherein said means of said telephone exchange for sending the control signal further includes means for looking up a table which stores said predetermined time for a plurality of kinds of accounting rates dependent on the distance of the communication within the telephone network.
