Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a telephone device,
More particularly, the present invention relates to a telephone device connected to a telephone line provided with a call termination destination notification service from a telephone network.

[0002]

2. Description of the Related Art In a public telephone network, a call end destination notification service is provided. This service is a service in which, when a calling party is busy, a predetermined registration operation is performed from the calling side telephone apparatus to the network side to notify the calling side telephone apparatus of the subsequent call destination end call. Hereinafter, FIGS. 8 to 1
With reference to FIG. FIG. 8 is a sequence diagram showing the operation of the call termination notification service, FIG. 9 is a signal waveform diagram showing an incoming signal at the time of call termination notification, and FIG. 10 is a timing chart of the call termination notification. .

In FIG. 8, a calling telephone device and a called telephone device are connected to a telephone network via telephone lines, respectively. First, it is assumed that the caller telephone device captures the telephone line in response to the user's operation and transmits the call destination, that is, the telephone number of the receiver telephone device, thereby making a call to the receiver telephone device (step 70). In response to this, the telephone network checks the status of the receiving telephone device, and if the receiving telephone device cannot be called, for example, when the receiving telephone device is busy with another telephone device, the receiving telephone device receives a busy tone. The side telephone device is notified that it is in use (step 71). In response, the calling telephone device disconnects the telephone line (step 72).

[0004] Here, when the user wants to make a telephone call to the called side, the user performs a service registration operation in order to use the caller's end-of-call notification service. First, the calling telephone device captures the telephone line and sends out a dial "159" (step 73). As a result, a voice message regarding the contents of the service is notified from the telephone network (step 7).
4). Then, by sending a dial "1" for instructing service registration from the calling side telephone device, service registration is performed (step 75), and a voice message regarding completion of service registration is notified from the telephone network (step 76). ), The registration process of the call destination end call notification service ends.

Accordingly, the telephone network starts a call destination call end notification service, and in response to the registered call termination of the called-side telephone device, the calling-side telephone device is called by an SIR incoming call described later (step). 80). When the originating telephone device responds to this SIR call (step 81), a voice message regarding the termination of the receiving telephone device is notified from the telephone network (step 82). As a result, the user knows that the receiving-side telephone device has finished talking and is ready to call, and once disconnects the telephone line (step 83).

Subsequently, the telephone line is recaptured and the dial "159" is transmitted (step 84).
A voice message about the contents of the service from the telephone network is notified (step 85). Then, by sending a dial "3" for instructing the other party to call from the originating telephone device (step 86), a call is made from the telephone network to the receiving telephone device (step 87). (Step 88), the calling telephone device and the called telephone device are connected via the telephone network,
A call between the two is started (step 89). By using such a destination-end-call notification service, the calling-side telephone device can know the end of the called-side telephone device, and can easily perform the operation after the destination-end notification from the telephone network. Can call the called telephone device.

In this service, when the telephone network notifies the calling side telephone device of the other party's end call, as shown in FIG. 9, an SIR incoming call different from a normal IR incoming call is used. As shown in FIG. 9B, the ringing pattern of the IR
Ringing for 1 second ON period (16H for analog telephone line)
z frequency signal) is repeated at a cycle of 3 seconds. On the other hand, in the ringing pattern of the SIR incoming call, 0.25 to 0.3
After a short on-period sound of seconds (t1),
There is a short off-period of 0.3 seconds (t2) and an additional 0.
A short on-period sound of 25 to 0.3 seconds (t1) is provided. And sandwich such a short off period,
Two on-period sounds (16 Hz for analog telephone lines)
Frequency signal) is 3 seconds cycle, 12 times in total (about 36 seconds)
Repeated.

In the telephone network, assuming that the originating telephone device cannot respond to such an SIR reception for some reason, as shown in FIG. 10, a 5-minute interval (T2) from the first SIR reception. Is used to call the outgoing telephone apparatus by using the SIR reception four times. At this time, the period during which the call can be recalled from the telephone network with the dial “3” following the dial “159” after responding to the SIR call is within 5 minutes from the response to the SIR call in consideration of the reduction of the load on the telephone network side. Is restricted to Further, when the response to the SIR call arrives, it is considered that the caller's end-of-call notification service has been completed. Therefore, for example, when responding to the first SIR call, the remaining three SIR calls are terminated.

In addition, when monitoring the call termination of the destination telephone device, a period during which the call termination of the destination telephone device is monitored, that is, the waiting time (T
1) is limited to 45 minutes from the point of service registration. As a voice message from the telephone network to the calling telephone device, a registration completion notification message (M
In addition to 1), there is an end-of-call notification message (M2) that is sent out when the calling telephone device responds to the SIR call. If the other party's call waiting time (T1) exceeds 45 minutes, a service end notification message (M3) is sent out when responding to the first SIR call.

[0010]

In such an end-of-call notification service, for example, a user presses the dial "159" to use this service, and then dials "1". When this service is registered on the telephone network side by pressing the button, the user is charged a predetermined registration fee. However, in the conventional telephone device, a telephone charge corresponding to an area code and a time zone is registered in advance in an internal table, and the dial number and the dial time transmitted by the user are detected, and the dial number and the dial Only the charge based on the call charge according to the area code and the time zone in the table corresponding to the time is performed, and the charge is displayed. For this reason, it is not possible to manage the charging fee to the user caused by the registration of the above-mentioned call termination notification service of the transmission destination, etc. There is a problem that the telephone number is not known, and therefore the call charge charged to the user cannot be managed.

Accordingly, an object of the present invention is to accurately manage a charging fee charged to a user.

[0012]

A clock circuit 14, a BT detection circuit 15, and a voice recognition circuit 16 are provided.

The diode bridge DB1 is connected to both ends of the analog telephone lines L1 and L2, rectifies the loop current from the analog telephone lines L1 and L2, and supplies the rectified loop current to the subsequent loop closing circuit 3 and communication circuit 5. . The loop connection circuit 3 is connected between the diode bridge DB1 and the communication circuit 5, and closes the DC loop of the analog telephone lines L1 and L2 according to an instruction from the CPU 1. A hook switch HS1 is provided in parallel with the loop closing circuit 3. The state of the hook switch HS2 linked with the hook switch HS1 is also input to the CPU1.

The diode bridge DB2 is connected to both ends of the analog telephone lines L1 and L2 via the capacitor C1, and receives an incoming signal (16 Hz frequency signal) from the telephone network.
And the rectified output is supplied to the incoming signal detection circuit 2. The incoming call detection circuit 2 identifies and detects a normal IR incoming call and an SIR incoming call used in the caller's call termination notification service based on the rectified output from the diode bridge DB2. Buzzer B according to the ringing pattern at the time of incoming call
Drive Z to send out a ringtone.

In response to an instruction from the CPU 1, the dial circuit 4 converts a predetermined dial signal such as "159" used in the destination telephone end-of-call notification service into an analog telephone through the loop closing circuit 3. Send to the lines L1 and L2. In the communication circuit 5, the handset TR is operated in accordance with the loop current supplied via the loop closing circuit 3 or the hook switch HS1 to perform a voice communication. In the case of the speaker receiving operation, the amplifying circuit 6 amplifies the call voice from the call circuit 5 and outputs it from the speaker SP. The voice recording / reproducing circuit 8 records the call voice from the amplifier circuit 6 as necessary, and further reproduces and outputs the voice to the amplifier circuit 6. Sound source circuit 7
Then, various signal sounds such as a ringing sound to the user, an alarm sound, and a confirmation sound are output to the amplifier circuit 6.

The CPU 1 operates according to a predetermined program stored in an internal memory (not shown) to control each circuit. The memory 11 stores information necessary for the processing operation of the CPU 1,
For example, while storing the operating state of the telephone device, the state of the destination communication end notification service, the shortened telephone number, the redial telephone number, and the destination telephone number of the transmission destination communication termination notification service, FIG. 2 and a charge management area 11B shown in FIG. 2 (b).

The display circuit 12 uses display elements such as LEDs and LCDs to display the states of the analog telephone lines L1 and L2,
In addition to visually displaying the operating state of the telephone device, the call charge, and the like, the status of the caller's call termination notification service is visually displayed. The printing unit 13 prints out call charges and the like. In the clock circuit 14, in addition to calendar management and timekeeping operation,
A clock signal of a predetermined frequency required for timekeeping processing using the timer 1A of PU1 is supplied to CPU1. The BT detection circuit 15 detects a BT (busy tone) arriving at the lines L1 and L2 and outputs it to the CPU 1. Voice recognition circuit 1
6 recognizes voice messages arriving on the lines L1 and L2 and outputs them to the CPU 1.

Next, the operation of the main part of the telephone apparatus will be described with reference to FIGS. First, the line transmission processing of FIG. 3A will be described. When the user goes off-hook to make a call to the destination, the analog telephone lines L1, L2 (hereinafter, lines L1, L2) are closed by closing the hook switch HS1.
2) is captured (step S1). Here, when the user operates the dial key 9 to dial the destination telephone number, the CPU 1 confirms off-hook according to the state of the hook switch HS2 and outputs these dial numbers to the dial circuit 4. As a result, a dial signal corresponding to the other party's telephone number is transmitted from the dial circuit 4 to the lines L1 and L2 via the loop closing circuit 3 (step S).
2).

In this case, if the other party corresponding to this telephone number is not busy, and therefore "other party busy?" In step S3 becomes "N", a call is made to the other party,
A call process is performed according to a response to the call of the other party (step S4). On the other hand, if the other party is busy, step S
The "other party busy?" Of No. 3 becomes "Y", and a busy tone is transmitted from the telephone network to the user side. In such a case, the user presses the on-hook notification service key in the function keys 10 to use the on-hook notification service of the outgoing call, or ends the call by on-hook.

Here, when the user presses the other party's end call notification service key, "press the end call notification service key?" In step S5 becomes "Y", and in this case, the CPU 1 terminates the call destination in step S7. Perform registration processing to register the notification service. On the other hand, when the user who hears the busy tone from the telephone network during the other party's talk on-hook to end the call, the CPU 1 detects the on-hook of the user based on the state of the hook switch HS2, and the "end call?" It is determined as “Y”. In this case, the capture state of the lines L1 and L2 is released (step S8), and the process ends.

Next, with reference to the flowchart of FIG. 3 (b), the above-described call destination end-of-call notification service registration processing will be specifically described. When the other party's end call notification service key is operated as described above, the above-mentioned call destination's end call notification service registration processing is performed. In this case, the CPU 1 stores the above-mentioned call stored in the redial area of the memory 11. The destination telephone number is copied to the idle dial area of the memory 11 (step S11). Thereafter, the CPU 1 automatically reacquires the lines L1 and L2 (step S1).
2) The dial circuit 4 sends out the dial "159" to the re-acquired lines L1 and L2 (step S13).
Further, the CPU 1 sets the dial “159” to the line L1,
After being sent from L2, a fixed pause time P is taken, and then dial "1" is dialed from dial circuit 4 to lines L1 and L2.
2 (step S14).

In response to the transmission of such a dial "159P1" (where P is a pause time), the telephone network performs registration processing of a service corresponding to the dial "159P1", and completes the registration of the service. The notification is made based on the presence / absence of the notification message and the transmission of the BT after a predetermined time. That is, when the service is registered in the telephone network, a voice message regarding the completion of the service registration is notified. In the telephone network, if the service cannot be registered after receiving the dial “159P1”, a BT (busy tone) is transmitted about 10 seconds later, and if the service can be registered, the BT is transmitted about 1 minute later. The telephone device determines whether or not the service is registered in the telephone network by a voice recognition circuit 16.
Is detected based on whether or not the message is recognized, or based on whether or not the BT is detected by the BT detection circuit 15 within a fixed time (for example, about 15 seconds) of the timer 1A. If it is determined that the service has been registered, the “service accepted?” Of step S15 is determined to be “Y”.

In this case, the CPU 1 displays the charge of 30 yen on the display circuit 12 and controls the printing unit 13 to print out on a recording paper (step S16). Further, the user is charged 30 yen as a service registration fee (step S17). That is, when it is determined that the service has been registered in the telephone network, the CPU 1 stores the clock circuit 1 in the charging management area 11B in the memory 11 as shown in FIG.
2 (for example, 00 / in FIG. 2B)
10:10:20 (October 10, 2000 at 10:20 am)), and stores and manages a service registration fee of 30 yen as a charging fee to the user, and also sets the transmission date and time and the service registration fee of 30 yen. The circle is recorded on the recording paper by the printing unit 13, and the service registration fee of 30 yen is displayed on the display circuit 12. Thereafter, when the lines L1 and L2 are released by the user on-hook (step S18),
The CPU 1 starts the idle waiting timer in the timer 1A (step S19).

On the other hand, if the service registration cannot be identified and the "service accepted?" Of step S15 becomes "N", the CPU 1 turns on the line L by the user on-hook.
When L1 and L2 are released (step S20), the timer 1
Start the idle waiting timer in A (step S2)
At the same time as 1), the 159 accounting flag provided in the memory 11 is set (step S22). In this manner, the registration processing of the call destination end call notification service is performed.

After the above-described registration processing of the call termination service by the CPU 1 by the CPU 1, if this service is registered in the telephone network, the telephone network monitors the call destination in the busy state and transmits the call. When the other party becomes free, the SIR incoming signal having a sound pattern different from the normal IR incoming sound pattern is sent to the user's telephone device.

When the CPU 1 identifies the ringing pattern of the incoming call which arrives at the lines L1 and L2 and is detected and output by the incoming call detection circuit 2, and determines that the incoming sound is an SIR incoming call different from the sounding pattern of the normal IR incoming call, In step S31 of 4 (a), it is determined whether or not the 159 charging flag has been set.
And if the 159 billing flag is not set,
The fact that the service has already been registered on the telephone network side when the dial "159P1" has been sent is identified by the CPU 1, and therefore a service registration fee of 30 yen has already been stored and managed in the charging management area 11B as a charging fee to the user. Further, it is determined that the service registration fee of 30 yen is displayed on the display circuit 12 or the like, and only the SIR incoming processing for displaying an SIR incoming call in a separate display area of the display circuit 12 is performed (step S35).

On the other hand, if the 159 charging flag is set, the CPU 1 cannot detect that the service has been registered on the telephone network side when the dial "159P1" is sent out. It is determined that charge management has not been performed, and a charge totaling process is performed (step S32). In this charge totaling process, the service registration fee of 30 yen is stored and managed in the charging management area 11B as described above as the charging fee to the user, and the fact is displayed on the display circuit 12 and the printing unit 13 The service registration fee of 30 yen is printed. Thereafter, the 159 charging flag is cleared (step S33), and the service charge display flag in the memory 11 is set (step S3).
4). Thereafter, an SIR incoming process for displaying an SIR incoming display on the display circuit 12 is performed (step S35).

When the user responds to such an SIR call by going off-hook, a call termination notification message indicating that the call destination has ended is notified from the telephone network. In this case, the user once goes on-hook to release the lines L1 and L2, then goes off-hook again and operates the dial key 9 to input a predetermined dial number. Then, the CPU 1 inputs this dial number in step S41 of FIG. 3B, and determines in step S42 whether or not the dial number is a dial "159P3" (where P is a pause time).

Here, the dial entered is "159P".
In the case of "3", the CPU 1 performs an idle waiting dial transmission process by retransmitting the call to the transmission destination (step S43). In this idle waiting dial transmission process, C
PU1 transmits the dialed number of the called party copied to the idle waiting dial area in the memory 11, and in this case, the CPU 1 preliminarily sets each area code and the telephone number for each time zone. Memory 11 in which carrier (line connection company) numbers are registered corresponding to charges
Referring to the table 11A shown in FIG. 2A, first, a time zone corresponding to the current time of the clock circuit 14 is selected, and the selected time zone matches the area code of the idle waiting dial area. And select the carrier number with the lowest call rate. Then, the selected carrier number is transmitted from the dial circuit 4 to the lines L1 and L2, and after selecting the line of the carrier, the dial number in the idle waiting dial area is continuously transmitted from the dial circuit 4 to the lines L1 and L2.

Calling of the calling party is performed by sending the dial number, and when the calling party answers the call, a call is started between the user and the calling party. During such a call, the CPU 1 determines whether or not the service charge display flag is set (step S44). If the service charge display flag is not set, the service registration charge is not displayed and the service registration charge is not displayed. Is stored and managed in the charge management area 11B as a charge to the user, and displayed on the display circuit 12, and the selected call charge is stored and managed in the charge management area 11B as a charge to the user. Then, the information is displayed on the display circuit 12 (step S45). Further, it controls the printing unit 13 to print the service registration fee and the call fee.

On the other hand, if the service charge display flag is set, it means that the service registration charge has already been displayed, so that only the display of the call charge is displayed on the display circuit 12 and printed on the recording paper by the printing unit 13 (step S1). S
46). That is, in this case, the transmission date and time (00/10/10 10:20 in FIG. 2B (October 1, 2000)
10:20 am on the 0th) and the service registration fee of 30 yen are stored and displayed in the charging management area 11B in the memory 11, and subsequently the transmission date and time by retransmission (FIG. 2B) 00/10/10 10:40 (2
2000, 10:40 am on October 10, 2000), its re-transmitted telephone number (06-4321-3333), and the call charge 60 charged to the user are stored and managed in the charging management area 11B. The charge is recorded on the recording paper by the printing unit 13 and the charge 60 yen is displayed on the display circuit 12.
To be displayed. In this case, the call fee of 60 yen may be added to the service registration fee of 30 yen and displayed. afterwards,
End call by user on-hook, or BT detection circuit 1
5 determines the end of the call destination based on the detected BT (step S47). If any end is detected, the CPU 1 counts only the call charges during this period and charges the user. The charge is stored and managed in the charge management area 11B, and is displayed on the display circuit 12 and the like (step S48). Then, the service charge display flag is cleared, and the process ends (step S49).

After the dial "159P1" is transmitted and the caller's call end notification service is registered, the user goes off-hook and dials "159P9" (however,
When the transmission operation of (P is a pause time) is performed, the CPU 1
It is determined that “159P9 dial?” In step S51 of (b) is “Y”. In this case, the CPU 1 determines whether or not the 159 charging flag has been set (step S52).
9 If the charging flag is set, it means that the call termination destination notification service is registered in the telephone network but is not charged, and the service registration fee of 30 yen is charged as a charging fee to the user. It is stored and managed in the management area 11B (step S53), and the indication of the 30 yen charge is displayed on the display circuit 12 and recorded on the recording paper by the printing unit 13 (step S54). Thereafter, the dial "159" is transmitted from the dial circuit 4 to the lines L1 and L2, and after the pause time P, the dial "9" is transmitted to the line L.
A dial transmission process for sending to L1 and L2 is performed (step S55). As a result, the telephone network cancels the registration of the call destination call end notification service.

If the 159 billing flag is not set when the dial "159P9" is transmitted, it means that the billing management and billing display for the registration of the service have already been performed. Dial "159" is sent from dial circuit 4 to lines L1 and L2.
After the pause time P, dial "9" to the line L
A dial transmission process for sending to L1 and L2 is performed (step S55). As a result, the telephone network cancels the registration of the call destination call end notification service. When the user goes off-hook and performs a dial operation other than the dials “159P3” and “159P9”, the dial operated in step S55 via “N” in step S42 and “N” in step S51 is transmitted from the dial circuit 4 to the dial circuit 4. A dial transmission process for making a transmission to the lines L1 and L2 is performed.

As described above, according to the present invention, as a call termination notification service for a call destination, when the call destination is busy, the line is reacquired and a predetermined dial is transmitted from the caller. By registering the end-of-call notification on the telephone network side, the call is connected to a line that provides a service for notifying the end of the call destination by a special incoming call to the caller from the telephone network. The telephone device detects whether a service has been registered in the telephone network after a predetermined service registration operation, and stores and manages a service registration fee in a charging management area when service registration is detected. Therefore, it is possible to store and manage the billing fee to the user generated by registering the call termination notification service, etc., so that the billing fee charged to the user can be accurately managed. .

Further, when a retransmission operation to the destination is detected after detecting the end notification signal for notifying the end of the destination transmitted from the telephone network after the predetermined service registration operation, the billing information is registered in advance. The charging of the user is controlled based on the charging table and the telephone number of the other party, and the call charge based on the result of the charging control is stored and managed in the charging management area. When the call is re-transmitted to the other party, the call charge can be accurately managed, and similarly, the charge to be charged to the user can be accurately managed. Further, the registration fee for the service is stored in the charging management area, and the call charge based on the result of the charging control is stored in the charging management area. Since the call charge when re-calling can be managed, more accurate charge management can be performed. In addition, since the transmission means for transmitting the information stored in the charging management area to the user is provided, the user can easily identify the amount charged to the user. In addition, since the transmitting means is a display unit or a printing unit, the billing fee can be transmitted to the user with a simple configuration.
