Next, a charge advance notification service in the ISDN network will be described with reference to FIG. 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 calling operation is performed by the user on the calling telephone device 21, and in response to this, a call setting 24 including the 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 the charge data relating to the call (communication) with the called telephone device 22, that is, the call charge, the information charge, and the information charge non-charging time by the charge notification 25, 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.

Thus, in the calling 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 fee notification information element identifier 31 stores an identifier indicating that the following data is the fee notification information, and the fee notification content length 32 stores the length of the fee 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 charge 36 is a charge that is charged in addition to the normal call charge 35 for the paid 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 telephone directory registration process. RAM6
When registering a new calling party in the management table in the (storage means 14), first, the name or name of the calling party is input by operating the key unit 8 by the user, and the dial number of the calling party is input. (Step 4
0), these are associated with each other and registered in the management table by the management means 13 (step 41).

Subsequently, as an outgoing call request, call setting data including the dial number and a request for a fee advance notification service is sent to the ISDN network (step 42). Then I
When the charge data notified from the SDN network is received by the receiving means 11 (step 43), the call charge 35 and the information charge 36 are obtained from the received charge data as shown in FIG.
And the information fee non-charging time 37 is detected by the detecting means 12 (step 44).

Then, the obtained call charge 35 and information charge 36 are registered in the management table in association with the callee information as call charges required for the call with the caller (step 45), and the line is released. (Step 4
6), a series of processing ends. The management table in the storage unit 14 is configured as shown in FIG. FIG. 5 is an explanatory diagram showing a configuration example of the management table.

Here, in correspondence with the name of the calling party, for example, "Taro Ando", the dialed number "03-123-
4567 "is registered, and the call charge of the caller is registered. In particular, call charges
Although the value notified from the SDN network may be registered as it is, each call charge notified on a different basis is converted into a predetermined base, for example, a call charge (yen) per 3 minutes of unit call time and registered. Alternatively, this can be displayed as a value that can be easily compared and recognized by the user.

The call charges are registered for each of a plurality of time zones. In FIG. 5, the call charges for the time zones A to N are individually registered. As these time zones, in addition to daytime, nighttime or midnight, Saturdays, holidays, public holidays, and the like are assigned.

Therefore, the call charges in the time zone at the time of the registration process are automatically registered at the time of the registration process, and the call charges in the other time zones are set in the same manner as described above when the line is idle in those time zones. In this case, the information may be acquired and registered from the ISDN. In this way, by registering separately based on the time zone where the call fee was obtained, even if the call fee differs depending on the time zone, it is possible to use the accurate call fee corresponding to each time zone. it can.

On the other hand, if no charge data is obtained from the ISDN network in step 43 (step 4
3: NO), the process proceeds to step 46, the line is released (step 46), and a series of processing ends. It should be noted that, even if a valid call charge cannot be obtained in step 44, the process may be similarly shifted to step 46 and terminated after the line is released.

As described above, when a new caller is registered in the telephone directory, the call charge with the caller is automatically set to IS.
Since the information is acquired from the DN network and registered in the management table in association with the destination information, the call rate can be used immediately after the new call destination is registered, and the call rate by the user is collected. The call charge is displayed and confirmed without the need for an operation for making a call, and it is possible to accurately determine whether to stop calling to an arbitrary destination or to suppress a long telephone call.

Not only when a new caller is registered, but also when, for example, a dial number or name is changed, a call charge for the caller is automatically acquired from the ISDN network and the registration is updated. You may. Also in this case, the user does not need to perform an operation for collecting the call charge.

Further, the call charge may be registered and updated automatically at the time of calling.
The operation of registering and updating the call charge when making a call using the call function of the telephone directory will be described below. FIG. 6 is a flowchart showing the call registration processing.

First, when a call operation is performed by the user operating the key section 8, it is determined whether or not the operation is a telephone directory call operation (step 100). YES), the name of the caller and the call charge selected by the operation are read out from the management table of the storage means 14 and displayed on the display means 18 (step 102), and the flow shifts to a loop for waiting for a call start instruction.

On the other hand, if the operation is not a telephone directory transmission operation (step 100: NO), it is determined that the transmission is a dial input transmission, and whether the same transmission destination as the input dial number is registered in the management table. It is determined whether it is (Step 101). Here, if the calling party of the same dial number is registered (step 101: YES),
Move to step 102.

As described above, when a call is made to the telephone directory, or when the same caller as the input dial number is registered in the management table, the call charge required for calling the caller in accordance with the call operation is reduced. Since it is automatically displayed, it is possible to check the exact charge required for the call with the calling party when making a call, and when the user makes a call, cancel the call to the specified destination or make a long call It is possible to accurately judge whether or not the suppression is necessary.

If it is determined in step 101 that a caller of the same dial number is not registered (step 101: NO), the process proceeds to a call waiting instruction waiting loop. In the transmission start instruction waiting loop, the detection of the start of the transmission operation (step 103) and the determination of the termination of the transmission (step 104) are performed. Here, if the operation for instructing the stop of the transmission or the loop is continued for a predetermined time or more, it is determined that the transmission is to be stopped (step 104: YES), and a series of the transmission processing ends.

On the other hand, when the transmission start operation is detected in the transmission start instruction waiting loop (step 10).
3: YES), the call setting data including the dial number and the request for the advance notice service of the call
The data is sent to the N network (step 105). Then ISD
If the charge data notified from the N network is received by the receiving means 11 (step 106: YES), the call charge is detected by the detection means 12 from the received charge data (step 107) and displayed on the display means 18. (Step 108).

Subsequently, if the calling party who is making a call is registered in the management table (109: YES), a new I
The latest call charge notified from the SDN network is compared with the call charge in the transmission time period registered in the management table (step 110). If the two do not match (step 111: YES), the user is notified by the display means 18 that the call charge has been changed (step 112), and the call charge of another call partner is updated. It is determined that it is necessary to perform the update, and system information indicating the necessity of updating is set in the storage unit 14 (step 113).

Thereafter, the call charge is registered and updated (step 114), and the call charge registration process at the time of calling the telephone directory is terminated, and the state shifts to a calling state and a subsequent call state. If both match in step 111 (step 111: NO), and if they are not registered in the telephone directory in step 109 (step 109: N
O) The call state and the subsequent call state are shifted without executing the call charge registration process.

Further, if the charge data cannot be received from the ISDN network in step 106 (step 10).
6: NO), without executing the call charge registration processing, the state shifts to the calling state and the subsequent calling state. Then, if there is a call termination operation in the subsequent call state (step 115: YES), the line is released, and a series of transmission processing ends.

As described above, at the time of making a call, the latest call charge is acquired from the ISDN network and updated as necessary, so that the latest call charge is automatically registered each time a call is made to each caller. Will be updated,
This eliminates the need for the user to perform operations for collecting call charges. In addition, not only when making a call from the phonebook, but also when the user directly enters a dial number to make a call, the dial number is detected and the corresponding call charge is registered and updated. Regardless of the difference, the call charge in the management table is reliably updated.

Next, if necessary, the telephone device
A case will be described in which a call charge is updated automatically when a line is idle. As described above (FIG. 6), if the calling rate of any of the calling parties is different from the latest one, the calling rate of the other time zone and further the calling rate of the other calling party will be reduced. Can also be determined to have been changed.

Accordingly, it is determined that the call charge needs to be updated, and if the update is set as the system information in the storage means 14, the following call charge update processing is executed to update the call charge. No registration updates for each call rate are made in order. If a call charge is registered for each time slot, a call charge update process as shown in FIG. 7 is performed when the ISDN line is idle in that time slot.

FIG. 7 is a flowchart showing the call charge updating process. First, from the management table of the storage unit 14,
It is determined whether or not there is a caller who has not processed the call charge for the time period (step 70). If there is a caller who has not processed the call charge (step 70: YES), the dial number and the request for the charge advance notification service are sent. Call setup data including ISD
It is sent to the N network (step 71). Then ISDN
When the charge data notified from the network is received by the receiving means 11 (step 72: YES), the call charge is detected from the received charge data by the detection means 12 (step 73).

Then, the obtained call charge is registered and updated as the call charge in the corresponding time zone of the corresponding destination information (step 74), and the line is released (step 7).
5) Returning to step 70, the processing for the next destination is executed. If the charge data cannot be received in step 72 (step 72: NO), the process proceeds to step 75.

On the other hand, in step 70, if there are no unprocessed callers except for those for which charge data could not be received (step 70: NO), a series of processing ends. In this way, as necessary, the call charges of each calling party in each time zone are automatically registered and updated, so that the user can make individual calls for a large number of calling parties and even for each time zone. Eliminates the need to set fees and saves a lot of work.

Next, as an example of the effective use of the call charge registered in the management table of the storage means 14, a case where the call charge is used for judging the presence / absence of transmission restriction will be described. FIG. 8 is a flow chart showing the call regulation control processing for telephone directory transmission. When a call is made by the telephone directory function, it is executed before shifting to actual call processing, and based on the processing result, that is, based on the presence or absence of call restriction. It is determined whether or not subsequent transmission processing can be performed.

First, the name or name of the caller is selected by the user operating the key section 8 (step 8).
0), the call charge of the calling party in the time zone is read from the management table of the storage means 14 by the management means 13 and displayed on the display means 18 (step 81). Subsequently, the comparison unit 16 stores the call charge and the storage unit 1.
4 is compared with the regulation amount set in advance (step 82).

In this case, when the base of the call charge is different from the base of the regulation amount, the base is converted into a predetermined base, for example, a charge per three minutes, and compared. If the call charge is equal to or less than the regulated amount (step 83: YES), "no call regulation" is set as the result of the call regulation decision (step 8).
4), a series of processing ends.

On the other hand, if the call charge is higher than the regulated amount (step 83: NO), "outgoing call restricted" is set as the outgoing call restriction determination result (step 85), and the outgoing call is visually displayed on the display unit 7, Or speaker S
Audible display by P or handset of handset HS (display means 1
The user is notified according to 8) (step 86), and the series of processing ends. As described above, the individual call charges registered for each caller are compared with a predetermined regulated charge, so that it is possible to accurately determine whether or not there is call regulation before performing the call processing. it can.

[0053]

As described above, according to the present invention, after transmitting the call setting data, it receives the charge data notified from the ISDN network, detects the call charge required for the call from the charge data, Means for associating destination information indicating the destination of a call with a call charge required for a call with the destination in a management table, and associating the detected call charge with the callee information of the destination. In addition, when an arbitrary destination is selected by a predetermined operation, a call charge corresponding to the destination information of the destination is read out from the management table and displayed. Therefore, when making a call, it is possible to check the exact charge required for the call with the caller, and when the user makes a call, it is possible to accurately determine whether it is necessary to stop calling the specified destination or to suppress long calls it can.
