Next, with reference to FIG. 2, a charge advance notification service in the ISDN network will be described. Figure 2 shows the IS
It is explanatory drawing which shows the charge advance notification service in a DN network, (a) is a system block diagram, (b) is a sequence diagram which shows operation | movement.

In FIG. 2A, a calling telephone device 21 is a telephone device to which the present invention is applied, and is accommodated in an ISDN network 23. Note that the receiving-side telephone device 22 directly
It is not necessary to be accommodated in the SDN network 23, and it may be connected to the ISDN network 23 via another network.

First, a user performs a calling operation on the calling telephone device 21, and in response, a call setting 24 including a dial number of the called telephone device 22 is sent from the calling telephone device 21 to the IS.
It is sent to the DN network 23. In this case, an activation number for activating the advance fee notification service is set in the call setting 24.

In accordance with the call setting 24, the ISDN network 23 transmits, based on the charge notification 25, the charge data relating to the call (communication) with the called telephone device 22, ie, the call charge, the information charge, and the information charge non-charging time. Notify the calling telephone device 21.
Almost in parallel with this, the ISDN network 23 sends out a call 26 to the destination telephone device 22 to start the call.

Thereafter, when a response operation is performed on the called telephone device 22, a response 27 is sent from the called telephone device 22 to the ISDN network 23, and a response is sent from the ISDN network 23 to the calling telephone device 21. 28 is sent out. This allows
The calling telephone device 21 and the called telephone device 22 are connected via the ISDN network 23, and a telephone call (communication) is started.

As described above, in the calling side telephone device 21,
By using the advance fee notification service, it is possible to acquire, from the ISDN network 23, fee data relating to a call (communication) with the called telephone device 22 at the time of calling, that is, a call fee, an information fee, and an information fee non-charging time. .

FIG. 3 is an example of a format showing fee data notified from the ISDN network. Note that this charge data is actually stored and notified in a predetermined message such as an additional information message sent from the ISDN network 23 to the calling telephone device 21.

The charge notification information element identifier 31 stores an identifier indicating that the following data is the charge notification information, and the charge notification content length 32 stores the length of the charge notification information. The information type 33 stores the type of each charge information stored in the information field 34 described later.
The information field 34 stores actual charge data, here, a call charge 35, an information charge 36, and an information charge non-charging time 37.

In particular, the information fee 36 is a fee charged in addition to the normal call fee 35 for the fee-based service provided by the called telephone device 22. Will be notified as needed. Generally, as for the charging of the information fee 36, the charging is started after a lapse of a predetermined time from the start of the telephone call (communication) with the called telephone device 22, as the paid service selection time by the calling user. The time is notified as the information fee non-charging time 37.

The call charge 35 is a pay-per-use system.
In addition to being notified of the time during which a call can be made with a predetermined amount (talk time per unit amount), such as being able to talk for 45 seconds at 0 yen, the amount charged per predetermined time (the amount per unit time) ). On the other hand, the information fee 36 is notified in the same manner as the call fee 35 in the case of the subordinate system, but one call (communication) in the case of the flat-rate system.
Only the amount charged for each is notified.

Next, the operation of the present invention will be described with reference to FIG. FIG. 4 shows the operation of the telephone device of the present invention.
It is a flowchart which shows a transmission process. In addition, the calling telephone apparatus sets a regulated call charge and a regulated information charge with respect to the call charge and the information charge as a condition for outgoing call regulation.
(See FIG. 1) and is registered in the RAM 6.

At the time of making a call, first, the user enters the key unit 8
Is operated to input a dial number (step 4).
0), call setting data including this dial number and a request for a charge advance notification service is sent to the ISDN network as a call request (step 41). Thereafter, the charge data notified from the ISDN network is received by the receiving means 13, and FIG.
As shown in (2), the detecting means 14 detects the call charge 35, the information charge 36, and the information charge non-charging time 37 (step 42).

Next, it is determined whether the fee data notified from the ISDN includes an information fee (step 43). If the information fee 36 is included, the information fee 36 and the regulated information fee are converted by the conversion / comparison means 15 into a unit amount basis or a unit time basis as necessary, and both are compared (step S1). 4
4).

Then, based on the result of the comparison, the necessity of transmission restriction is judged by the transmission restriction means 16 (step 4).
5). At this time, if the notified information fee 36 is equal to or more than the regulation information fee, it is determined that transmission regulation is necessary (step 45: YES), and the display is visually displayed on the display unit 7 or the handset HS. The user is notified by an audible display that the transmission to the dialed number is restricted (step 48), and the line is released (step 4).
9).

On the other hand, if the notified information fee 36 is less than the regulation information fee, it is determined that the transmission regulation is unnecessary (step 45: NO), and the process proceeds to the transmission regulation determination based on the call fee 35. I do. First, the conversion and comparison means 15 converts the call charge 35 and the regulated call charge into a unit amount basis or a unit time basis as necessary, and compares them (step 46).

Then, based on the comparison result, the necessity of transmission restriction is judged by the transmission restriction means 16 (step 4).
7). At this time, if the notified call charge 35 is equal to or greater than the regulated call charge, it is determined that call regulation is necessary (step 47: YES), and the aforementioned step 4 is performed.
8 and the user is notified that transmission to the dialed number is restricted (step 48), and the line is released (step 49).

On the other hand, if the notified call charge 35 is less than the regulated call charge, it is determined that the call regulation is not necessary (step 47: NO), the call processing is terminated, and the call is terminated. Move on to processing. As described above, the necessity of the outgoing call regulation is determined based on the latest charge data notified from the ISDN network for each call before the call starts.
The user does not need to manage the charge setting as in the related art, and the call regulation based on the charge can be accurately performed for each call with a very small work load.

Further, not only the notified call charge 35 but also the information charge 36 is compared with the regulated information charge, and if either the call charge or the information charge is higher than the call control condition, the call is regulated. As a result, it is possible to accurately regulate outgoing calls for which the information fee is high, as compared to the case where outgoing calls are restricted based on only the call charges. In addition, using only one of these call charges and information charges,
Transmission restriction may be performed.

Further, FIG. 4 illustrates an example in which the information fee is compared with a regulated information fee that has been set and registered in advance, as in the case of the call fee, to determine whether transmission regulation is necessary. However, the necessity of transmission regulation may be determined according to the presence or absence of an information fee. For example, if it is confirmed in step 43 that the information fee 36 of a valid value has been notified from the ISDN network (step 43: Y
ES), skips steps 44 and 45 and proceeds to step 48
, And the call may be immediately regulated.

Next, a description will be given of a method of setting outgoing call restriction conditions and an actual amount comparison process. When the regulated call charges and the regulated information charges are set and registered in the telephone device in advance, as a method of setting the regulated conditions, there is a method of setting an amount charged per unit time, for example, 50 yen on a 3-minute basis. is there. On the other hand, there is a method of setting a time during which a call can be made with a unit price, for example, 10 seconds on a 100 yen basis.

In any case, both the time and the amount of money may be set by the user, and the user can set the regulation condition in arbitrary units. The unit time or the unit price may be fixed in advance by the telephone device itself, and the user may set either the amount or the call time serving as the regulation condition, thereby setting the calling regulation condition. Operation burden can be reduced.

As described above, there are two notification methods for the call charge and the information charge notified from the ISDN network, as there are two kinds of the calling restriction conditions on the telephone device side, that is, the unit time base and the unit price base. is there. In the present invention, as shown in FIG. 1 (a), a conversion comparing means 15 is provided so that the conversion conditions are converted so that the regulation condition on the telephone device side and the base of the communication charge and the information charge notified from the ISDN network match. Comparing.

FIG. 5 is an explanatory view showing a specific example of the determination of the necessity of outgoing call restriction, and shows a case where the call charge notified from the ISDN network is converted into a unit time base and compared with the regulated call charge. As shown in FIG. 5 (a), as a regulated call charge, a unit time base of 3 minutes and 50 yen is set in advance, and if a call charge of 45 seconds base of 10 yen is notified from the network, this call charge is reduced to the unit time. Converted to a 3 minute base.

In this case, the call charge from the network is 4
It is 0 yen, which is less than the regulated call charge, so it is determined that outgoing calls are possible. On the other hand, as shown in FIG. 5 (b), when a communication charge of 20 yen on a 45-second basis is notified from the network, the communication charge from the network is converted to 60 yen on a 3-minute basis, which is higher than the regulated call charge. Is determined to be outgoing.

FIG. 6 is an explanatory diagram showing another specific example of the determination of the necessity of regulation, showing a case where the information fee notified from the ISDN network is converted into a unit amount basis and compared with the regulated information fee. ing. As shown in FIG. 6 (a), a unit price of 100 yen base 10 seconds is set in advance as a regulation information fee, and when an information fee of 45 seconds base 10 yen is notified from the network, this information fee is set to the unit price. It is converted to 100 yen base.

In this case, the information fee from the network is 20 seconds on a 100 yen base, which is less than the regulation information fee, so it is determined that transmission is possible. On the other hand, as shown in FIG.
When the information fee of 50 yen per second is notified, the information fee from the network is 8 seconds per 100 yen by conversion, and it is judged that transmission is impossible because it is more than the regulated information fee.

FIG. 7 is an explanatory view showing another specific example of the determination of the necessity of regulation. In the case where the information fee notified from the ISDN network at a fixed amount is regarded as a unit time basis, converted and compared with the regulated information fee. It is shown. As shown in FIG.
A unit price of 100 yen base 50 seconds is set in advance as a regulation information fee, and when the information fee of a fixed amount of 100 yen is notified from the network, this information fee is regarded as an amount of 60 seconds per unit time and converted. . As the unit time, a time set by the user may be used, or a fixed time in the telephone device may be used.

In this case, the information fee from the network is 60 seconds on a 100 yen basis, which is less than the regulation information fee, so it is determined that transmission is possible. On the other hand, as shown in FIG. 7 (b), when the information fee of the fixed amount of 150 yen is notified from the network, the information fee from the network is converted into 100 yen base 40 seconds by conversion, and is transmitted because it is more than the regulated information fee. It is determined to be impossible.

In the above description, the case where the communication charge or the information charge notified from the ISDN network is converted and compared with the transmission restriction condition has been described as an example, but the transmission restriction condition is converted and notified from the network. The call fee or the information fee may be compared. Alternatively, both may be converted to a fixed base, for example, a base of 1 yen per unit or a base of 1 second per unit of time, and the transmission restriction conditions set and registered by the user may be converted into these bases in advance. It may be stored.

[0042]

As described above, according to the present invention, the receiving means for receiving the charge data notified from the ISDN after the transmission of the call setting data at the time of calling, and the communication from the charge data received by the receiving means to the call. Detection means for detecting a required charge and transmission restriction means for restricting transmission based on a charge required for a call obtained from the charge data by the detection means. The outgoing call is regulated based on the charge required for the call. Therefore, as before,
Investigate the call charges and information charges for each call destination, and compare them with those that individually set the necessity of outgoing call restriction for these numbers. Outgoing calls can be regulated.
