BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ISDN terminal device connected to an ISDN (Integrated Service Digital Network) that provides information between users.

0002

[Prior Art] In recent years, ISDN has become popular, and
A large number of various ISDN terminal devices connected to the Internet have been developed. One of the characteristics of communication using ISDN is that billing information is sent to the ISDN terminal device after communication, allowing users to know the cost of each communication. .

[0003] Also, some ISDNs, such as INSnet in Japan, provide information between users (user-to-user information) using the D channel.

By using such inter-user information, it becomes possible to exchange information for setting protocols, code systems, etc. between ISDN terminal devices before setting up a B channel.

[0005]

[Problem to be solved by the present invention] However, currently INS
On the Internet, billing information does not include usage fees for user-to-user information, and even when using a network where billing information includes usage fees for user-to-user information, the billing information is not sent to the calling party. Therefore, when the called side uses inter-user information, there is a problem in that neither party is notified of the communication charges.

The present invention has been made in view of the above circumstances, and provides an ISDN terminal device that allows both the calling side and the called side to know the usage fee for information between users used for communication. The purpose is to

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides, in an ISDN terminal device connected to an ISDN that provides user-to-user information, a registration means for registering communication charges for the user-to-user information; a storage means for storing the number of times the user-to-user information was used from the start of calling or receiving the call until the end of the disconnection; and a notification means for notifying the calling side and the called side of the usage fee calculated by the calculating means. .

[0008]

[Operation] Communication charges for user-to-user information are registered in the registration means, and the number of times the user-to-user information is used from the start of calling or incoming calls to the end of disconnection is stored in the storage means and registered in the registration means. Based on the communication fee and the number of uses stored in the storage means, the calculation means calculates the usage fee for the information between users, and the calculated usage fee is sent to the calling and called parties by the notification means. will be notified.

[0009] This makes it possible for both the calling side and the called side to check the usage fee for the inter-user information used for communication.

[0012] Table 1 below is a classification table of user information standardized by CCITT (International Telegraph and Telephone Consultative Committee) and TTC (Telegraph and Telephone Technical Committee), and as is clear from this table, service 1 is information between users that is transferred in call control messages such as call setup, paging, response, circuit disconnection, etc. at the time of call setup and disconnection. Service 2 is inter-user information that is transferred using a user information message between calling and answering during call setup. Service 3 is
This is information between users that is transferred using user information messages during communication. As of 1990, INS Net only provides Service 1.

[0013]

[Table 1] Next, Figure 2 shows an example of the flow of inter-user information transmitted and received between ISDN terminal devices from the start of call setup to the end of call disconnection.
This will be explained based on the sequence diagram.

In the figure, an ISDN terminal device 11 on the calling side communicates with an ISDN terminal device 12 on the called side via an ISDN 13. In FIG. 2, messages containing inter-user information include a call setup message, a paging message, a response message, a disconnection message, and a user information message.

First, at the time of call setup, the ISDN terminal device 11 on the calling side notifies the ISDN terminal device 12 on the called side of user information included in a call setup message (steps S1 and S2). Then, the call setting is accepted (step S3), and the inter-user information is reported from the ISDN terminal device 12 on the called side to the ISDN terminal device 11 on the calling side in a paging message (steps S4, S5).

Next, the process continues until user-to-user information is notified from the ISDN terminal device 12 on the called side to the ISDN terminal device 11 on the calling side in a response message (step S1).
0, S11), inter-user information carried in a user information message can be transmitted and received between the ISDN terminal devices 11 and 12 an arbitrary number of times (steps S6 to S9).

[0017] After confirming the response (step S12), user information can be sent and received any number of times between the ISDN terminal devices 11 and 12 in the user information message during communication as well (steps S13 to S16). ).

At the time of disconnection, the ISDN terminal device 12 on the called side notifies the user-to-user information included in the disconnection message to the ISDN terminal device 11 on the calling side (steps S17, S18).

In FIG. 2, the ISDN terminal 11 on the calling side
uses inter-user information in each step S1, S6, S13, and S19. In addition, the I
The SDN terminal device 12 performs each step S4, S8, S10,
In S15 and S17, inter-user information is used, respectively.

Next, in FIG. 2, the processing procedure for calculating and displaying the usage fee for the inter-user information used by both ISDN terminal devices 11 and 12 will be explained in FIGS. 3 and 4.
This will be explained using a flowchart.

FIG. 3 is a flowchart showing the basic operation of the ISDN terminal device 1 of the present invention.

First, in a standby state, it is determined from the input unit 8 whether there is a request for registration of communication charges for information between users (step S1), and if there is a request, the communication charges are input via the input unit 8 and the display unit 9. (Step S2) At the same time, R
The information is stored (recorded) in AM4 (step S3) and the present processing operation is ended.

[0023] Note that the initial value of the communication charge is the communication charge at the time of factory shipment (for example, in the case of INS Net, 1990
As of 2017, the price is set at 0.4 yen). If there is no request in step S1, it is determined whether there is a call (step S4), and if there is, the count value of the counter for counting the number of times the user-to-user information is used is set to "0".
” (step S5), and the calling procedure (step S6
), communication procedure (step S7), disconnection procedure (step S
8) respectively.

The message transmission processing operation in each of the steps S6 to S8 is shown in the flowchart of FIG. That is, in FIG. 4, when a call process is first performed (step S1), it is determined whether or not inter-user information was used when performing the call process (step S1).
2). If it is used, the count value of the counter is incremented by one (step S3) and the present processing operation is ended. Moreover, if it is not used, this processing operation is ended without executing step S3.

Based on the flowchart of FIG. 4, after performing the calling processing operation in each step S6 to S8 of FIG. If it is not received, step S9 in FIG. 3 is executed until it is received. If it is received, the communication at the time of calling is completed and the count value of the counter is set to R.
The usage fee for the inter-user information required for the communication is calculated by multiplying by the communication fee stored in AM4 (step S10 in FIG. 3).

Then, the calculated usage fee information is output to the display unit 9 and the printer unit 10, and the usage fee is displayed on the display unit 9 and printed by the printer unit 10 (see FIG. 3). Step S11), and then the present processing operation ends.

On the other hand, in step S4 of FIG.
If there is no call, the process proceeds to step S12 to determine whether there is an incoming call, and if there is no incoming call, the process ends.

[0028] Furthermore, when there is an incoming call, the count value of the counter for counting the number of times the inter-user information is used is set to "0" (step S13 in FIG. ), an incoming call procedure (step S14), a communication procedure (step S15), and a disconnection procedure (step S16).

In each of these steps S14 to S16, as in the case of the above-mentioned call, the message is sent based on the flowchart shown in FIG. to the count number of R
The usage fee for the inter-user information required for communication is calculated by multiplying by the communication fee stored in AM4 (step S17 in FIG. 3).

[0030]Then, the calculated usage fee information is output to the display unit 9 and printer unit 10, and this usage fee is displayed and printed (step 18 in FIG. 3). After this, this processing operation is performed. finish.

[0031] In the above-described embodiment, the usage fee information of the inter-user information is output after the end of each communication, but the information is not limited to this. After the communication charge is stored in the RAM 4, it may be automatically output.

[0032] Furthermore, in the ISDN terminal device on the calling side, the usage fee for the inter-user information may be added to the amount of the billing information sent after the communication, and then displayed and printed.

[0033]
