Abstract

PURPOSE:To display and recognize a communication charge for each terminal equipment by adding and storing a communication charge corresponding to a subaddress to a memory corresponding to the subaddress of each terminal equipment. CONSTITUTION:When a calling is made from one of plural terminal equipments TE1-TE8, the calling is detected by a line monitor 6 and its outgoing number and a subaddress are sent via a line 5. When the end of communication is detected and the presence of the caller is discriminated, the communication charge received via an ISDN line 1 is received by the monitor 6. A control collection circuit 7 adds a data representing the received communication charge and stores it to a storage area storing the communication charge corresponding to the calling terminal equipment in a memory 10. The communication charge charged by the communication of the terminal equipment is integrated and revised in a storage area storing the communication charge of the subaddress corresponding to the calling terminal equipment. The storage content of the memory 10 is given to an output circuit 8 and printed out on recording paper 9 for each subaddress.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to ISDN (Integrated Digital Communication Network)
ated 5ervieee Digital Netw
Regarding devices that communicate using ISDN lines, more specifically, we will introduce a new communication fee system that allows you to manage communication fees by receiving data representing communication fees at the end of communication via the ISDN line. Connect to manageable ISDN communications equipment.

Conventional technology In the analog telephone network that has been used for a long time.

Communication f1 from the telephone office! Il notifications are not sent for each communication.In the past, you could only find out about your communication charges by receiving a monthly bill or postcard from the telephone office that contains the details of your communication charges. .

Problems to be Solved by the Invention It is an object of the present invention to provide a new communication fee management system that enables communication fees to be successfully managed and known.
An object of the present invention is to provide an SDN communication device.

Means for Solving the Problems The present invention provides 'l'! for one calling number of an ISDN line. The terminal is connected by adding a number of sub-addresses, and at the end of the communication, the data representing the communication fee is sent to the calling party from the ISDN.
ISD that can manage communication charges received via line
The N communication device has an individual storage area corresponding to the sub-address of each terminal, and this store WI area has a memory for storing communication charges and a memory for storing communication charges via the ISDN line. A method for managing communication charges characterized by comprising: means for adding and storing in a store area corresponding to a sub-address of a terminal that has been sent, and means for displaying communication fi money stored in a store area of a memory. It is an ISDN communication device.

According to the present invention, a terminal is connected by adding a plurality of subaddresses f1 to one calling number of an ISDN line. This terminal may be, for example, a facsimile device or a telephone.

When making a call, each terminal transmits its calling number and subaddress to the ISDN line. The subaddress at the time of this call is detected. I at the end of the communication
Data representing communication charges received via the SDN line is detected. The memory has individual storage areas corresponding to the sub-address of each terminal, and data representing the received storage area is stored in the storage area individually corresponding to the sub-address of the terminal that made the call. Add and store.

Therefore, the communication charges stored in the storage area of this memory are printed on recording paper and displayed, or visually displayed on a liquid crystal display element, cathode ray tube, etc., or audibly displayed to calculate communication charges. You can know this for each terminal. In this way, communication charges can be managed successfully.

Embodiment FIG. 1 is a block diagram of an embodiment of the present invention. IS
DN line 1 has DS U (DigiLalServ
A charge information management device 3 is connected via a line 4 via the ice l1nit) circuit 2 . This charge information management device 3 connects a plurality of terminals TEI to TE via a line 5 (in this embodiment, a maximum of 8 terminals) as shown in FIG.
8 are commonly connected in a so-called multi-point connection. Terminal I! TE1 to TE8 may be, for example, facsimile means or alternatively telephones.

When these terminals TEI to TE8 make a call, as shown in FIG. B and other information C are sent to the ISDN line 1 via the line 5, further via the line monitor 6 of the rate information management device 3, and further from the line 4 via the DSU circuit 2.

This calling number A is sent from the other party via I SDN line 1.
By inputting and specifying subaddress B, one of the terminals IITE1 to TE8 can be selectively called.

The line monitor 6 detects and monitors the electric signal of the basic interface flowing to the line 4.5 (S point), and in particular, the subaddress at the time of calling and the signal received from the ISDN line 1 at the end of the communication. The data representing the communication charges received is detected and provided to a control/summing circuit 7 realized by a microcomputer or the like. An output circuit 8 is connected to this circuit 7 . The output circuit 8 is, for example, a printer, and can print and display communication charges individually corresponding to the terminal devices to TE8 according to the subaddresses on the recording paper 9. The output circuit 8 may be a visual display means such as a liquid crystal display element or a cathode ray tube, or may be an audio output display means having an audio generation circuit.

A memory 10 is connected to the control/summing circuit 7. As shown in FIG.
A store charge for storing communication charges is prepared for each sub-address individually corresponding to 8.

Referring to FIG. 5, when making a call and communicating with one of the plurality of terminals TE1 to TE8, the process moves from step n1 to step n2 as shown in FIG.
The line monitor 6 in the t'+* information management device 3 detects that the call is an outgoing call, and at this time, one of the terminals to the TE8 making the outgoing call, for example, sends the calling number and subaddress. It is sent out via line 5. The line monitor 6 detects this subaddress in step rr3. The IIIrn/aggregation circuit 7 is in a ready state for updating by adding the communication charge to the storage area of the memory 10 corresponding to the sub-address detected by the line monitor 6.

Referring to FIG. 6, when the communication ends, the end of the communication is detected in step rn2, and it is determined in step m3 that it is the calling party. ′
Qr! ' If it is determined that it is the P side, step m4
Then, the communication charge received via the ISDN line 1 is received at the line monitor 6. In step rn5, the III/AM aggregation circuit 7 adds data representing the received communication charge to a store area in the memory 10 for storing the communication charge corresponding to the calling terminal, for example, and stores the added data. In this way, the terminal If! The communication charges charged when the TE L communicates are accumulated and updated. Thereafter, in step m6, the device enters a receiving state and waits.

The contents stored in the memory 10 can be printed on a recording paper 9 by the output circuit 8 by the function of the control/summing circuit 7, and can be printed and displayed for each sub-address of each terminal to TE8.

Effects of the Invention As described above, according to the present invention, a plurality of sub-addresses are added to one calling number and the terminals are connected to each other, and a memory corresponding to the sub-address of each terminal is stored in memory. Since the communication charges are added up and stored, the communication charges for each terminal can be displayed and known, thus making it possible to successfully manage the communication charges for each terminal.
