Description

[Detailed Description of the Invention] [Summary] Regarding a call waiting service control method for controlling the operation of a call waiting service, an object of the present invention is to enable a subscriber to stop a call waiting service for a subscriber who has registered the call waiting service. and a signal sending means for sending a service stop signal requesting a switch to stop the call waiting service to a registered terminal of a subscriber who has registered a call waiting service; and a call waiting service control means that receives the service stop signal from the signal receiving means and stops the call waiting service of the registered terminal.

[Industrial application field]

The present invention relates to a call waiting service control method for controlling the operation of a call waiting service.

In recent years, call waiting services that notify callers of incoming calls during calls have been widely used.

This call waiting service is a service that, when a subscriber who has been registered in advance as a user of the call waiting service receives a new call from a third party while the subscriber is on the phone, the exchange sends a call to the subscriber's terminal (hereinafter referred to as the registered terminal). This is a service that notifies you of an incoming call by sending an incoming call notification sound to a person (described below).

When the caller on the registered terminal listens to the incoming call notification tone and performs hooking, he or she can put the current caller on hold and answer the new caller, and when he or she hooks again, the caller will be connected to the first caller who was on hold. You can now make calls.

However, in conventional call waiting services, if the call cannot be answered because the current call is important, or if the registered terminal is engaged in non-voice communication such as facsimile, the call cannot be answered. There is no way for the subscriber to stop the call waiting service even in cases where it is desired not to include sounds that interfere with communication, such as notification sounds. Therefore, even if an important call or facsimile is in progress, if a new call arrives, an incoming call notification tone will be emitted, interrupting the call or communication, and may even prevent you from answering the new incoming call. The result is that the user is forced to send out a ringing tone and wait for a response.

In light of the above, there is a need for a call waiting service control system that allows the subscriber to stop the registered call waiting service.

[Conventional technology]

FIG. 4 is a block diagram of the prior art.

The registration terminal 51 of subscriber A who has registered the call waiting service is a call waiting equipment (CWE) 52
The communication path network (NW) 54 of the exchange 50 via
However, it has two terminals for the communication path network 54, a first terminal 53-1 and second terminals 53-2. Normally, the connection to and from the registration terminal 51 is made through the first terminal 53-I;
For example, when the registered terminal 51 receives a call from another subscriber C while talking with subscriber B, the call control device (CC) 55 of the exchange 50 queries the subscriber file 56 for subscriber accommodation location information. When the first terminal 53. , , are in use, the accommodation position of the second terminal 53-2 is answered.

As a result, when the call control device 55 connects the subscriber C to the second child 531, the call waiting device 52 sends an incoming call notification sound to the registered terminal 51 for a short period of time. In addition,
Generally, the incoming call notification sound is sent only to the 51 registered terminals. Furthermore, in this state, the registered terminal 51 and the subscriber C are separated within the call waiting device 52, so they cannot talk on the phone yet.

When the subscriber A of the registered terminal 51 who has heard the incoming call notification tone interrupts the call and performs hooking to answer the incoming call, the call line is switched in the call waiting device 52, and the subscriber who was in the middle of the call is switched. Subscriber B is placed on hold, and subscriber C, who has received a new call, connects to the registration terminal 51 at the second terminal 53-.
The connection is made through t, and calls are possible. Registration terminal 51
When the call between subscriber A and subscriber C ends, and the communication is performed again at the registered terminal 51, the call line is switched again in the call waiting device 52, and the registered terminal 51 and subscriber B, who is the first party to the conversation, are connected again. You can now make calls.

However, when the incoming call notification sound is sent out in the above process, the call is interrupted for a short time, and if the call is not a voice conversation but a data communication or facsimile communication, the data and images being sent and received may be affected. An abnormality occurs. For this reason,
It is effective to stop the call waiting service during important calls, data, facsimile, etc. communications, but in conventional technology, it is not possible to stop the call waiting service from the subscriber side. .

[Problems to be Solved by the Invention] In the conventional technology, once the call waiting service is registered, the subscriber cannot stop the call waiting service. There was a drawback that communication was interrupted by the incoming call notification sound.

An object of the present invention is to enable a subscriber to stop a call waiting service for a subscriber who has registered the call waiting service.

[Means for Solving the Problems] Figures 1 and 2 are basic configuration diagrams of the present invention, and Figure 1 shows a system in which a registered terminal for a call waiting service sends a service stop signal to an exchange when making a call or during communication. The basic configuration diagram of the call waiting service control system that stops the call waiting service by calling the registered terminal. Figure 2 shows the calling terminal that makes a call to the registered terminal and sends a service stop signal to the exchange along with the telephone number of the registered terminal to which it is connected. FIG. 2 is a basic configuration diagram of a call waiting service control method for stopping the call waiting service of a registered terminal.

In the figure, 10a and 10b are registered terminals, and 20a is a terminal of a subscriber who has registered the call waiting service.

2Qb is an exchange having a call waiting service function, and 30 is a calling terminal that communicates with the registered terminal 10b. Further, 11 is a signal sending means provided in the registration terminal 10a and sends a service stop signal requesting the exchange 20a to stop the call waiting service when the registration terminal 10a makes a call or during communication; 12 is a registration terminal communication circuits 10a and 10b; 31 is a signal sending means provided in the calling terminal 30 for sending a service stop signal requesting the exchange 20b to stop the call waiting service of the registered terminal 10b when a call is made;
2 is a communication circuit within the calling terminal 30;

22a and 22b are signal receiving means provided in the exchanges 20a and 2Ob, respectively, and 22a is the registration terminal 10a.
22b is a signal receiving means for receiving the telephone number of the registered terminal and the service stop signal from the calling terminal 30, and 21a and 21b are the switching equipment 20a, respectively. , 20b
A call waiting service control means provided in the terminal receives the service stop signal or the telephone number and service stop signal of the registered terminal from the signal receiving means 22a or 22b, and stops the call waiting service of the registered terminal 10a or 10b. 23 is a communication monitoring means that is connected to the registration terminals 10a and 10b in the exchanges 20a and 20b and monitors the completion of communication of the registration terminals 10a and io'b; 24 is a communication monitoring means of the exchanges 20a and 20b; Call path network (
NW).

[For production]

In FIG. 1, when the registered terminal 10a sends out a service stop signal using the signal sending means 11 when making a call or during communication, the signal receiving means 22a of the exchange 20a receives it and sends it to the call waiting service control means 21a. Forward. The call waiting service control means 21
When a receives the service stop signal, the registered terminal 10
Stop a's call waiting service. While the call waiting service is stopped, the call waiting service is not performed for an incoming call while the registered terminal 10a is communicating, and a busy tone is outputted for the incoming call using a known method.

The call waiting service may be restarted automatically upon termination of the communication that sent the service stop signal, or the registered terminal 10a may use the signal sending means 11 to restart the service at the exchange 20a when the registered terminal 10a makes a call or during communication. This is done by sending out a signal. When restarting due to the end of communication, the communication monitoring means 23 detects the end of communication of the registered terminal 10a and notifies the call waiting service control means 21a, and the call waiting service control means 21a restarts the service. In addition, when restarting with a service restart signal, the exchange 20a
The signal receiving means 22a receives the service restart signal from the registered terminal 10a in the same way as receiving the service stop signal, and transfers it to the call waiting service control means 21a,
The call waiting service control means 21a restarts the service.

In FIG. 2, the calling terminal 30 that communicates with the registered terminal 10b sends out the telephone number of the registered terminal 10b and a service stop signal requesting to stop the call waiting service of the registered terminal 10b when making a call. The means 31 sends it to the exchange 20b. In the exchange 20b, the signal receiving means 22b receives this and transfers it to the call waiting service control means 21b, which stops the call waiting service of the registered terminal 10b and connects to the registered terminal 10b.

The call waiting service is basically restarted automatically upon termination of the communication that sent the service stop signal. That is, the call waiting service control means 21'b connects the calling terminal 30 to the registration terminal 10b, and when the registration terminal 10b responds, the communication monitoring means 24
monitors the communication of the registered terminal 10b, and when the communication is completed, it notifies the call waiting service control means 21b to release the stoppage of the call waiting service for the registered terminal 10b.

〔Example〕

FIG. 3 is a block diagram of an embodiment of the present invention, and shows a structure having all the functions shown in the basic block diagrams of FIGS. 1 and 2.

In the figures, the same symbols are used for the same objects as in Figures 1 and 2, but when one component serves as multiple components across Figures 1 and 2, numerical symbols are used. For example, the registration terminals 10a and 10b will be written as the registration terminal 10, and the exchanges 20a and 20b will be written as the exchange 20. In the figure,
Reference numeral 22 denotes an originating register (OR), and a signal receiving circuit 23 receives a dial signal, a service stop signal for a call waiting service, or a service restart signal from the registration terminal 10 or the calling terminal 30 when making a call or during communication.
23 is a subscriber circuit (LC) with a communication monitoring function, 23T is a trunk (TRK) which also has a communication monitoring function, 24 is a communication network (NW) of the exchange 20, and 25 is a call connection control in the exchange 20. call control device (C
C), 26 is a connection processing unit that performs call connection processing within the call control device 25; 27 is a connection processing unit that carries out call connection processing in the call control device 25; 27 stores subscriber information including whether the subscriber has registered for a call waiting service and the service status (whether or not it is stopped); The stored subscriber file 28 is an information receiving and distributing device (hereinafter referred to as SRD) that transmits and receives information between the communication path section of the exchange 20 and the call control device 25.

Referring to FIG. 3, one of the operations shown in FIG. 1, in which the registration terminal 10 requests stop of the call waiting service when making a call, will be explained. When the registered terminal 10 makes a call by going off-hook with a handset (not shown), the subscriber circuit 23 corresponding to the registered terminal 10 is connected to the calling register 2 via the channel network 24 in the exchange 20.
Connected to 2. The calling register 22 is normally connected to receive dialing signals. In this state, if the registration terminal 10 wants to stop the call waiting service until it sends a service restart signal using the keypad 11 such as a button dial that constitutes the signal sending circuit, the service stop signal requesting the stop may be, for example, "## 3'', the calling register 22 identifies this as a service stop signal and sends it to the call control device 25 via 5RD2B. In the call control device 25, the call waiting service control unit (hereinafter referred to as CW control unit) 21 receives the service stop signal, but the CW control unit 21 sends the service stop signal via the connection processing unit 26. The accommodation location or telephone number of the registered terminal 10 is identified, and the call waiting service of the corresponding registered terminal IO in the subscriber file 27 is stopped. At this time, the connection processing unit 26 sends a service tone or talkie to the registration terminal 10 via the transmission register 22 to notify that the service stop signal has been received. Registration terminal 10
If the above-mentioned call is only for the purpose of requesting termination of call waiting, the service tone is heard and the call is turned on-hook. After this, while the registered terminal 10 is communicating, the registered terminal 1
When there is an incoming call to 0, call waiting service is not performed, and a busy tone is sent to the caller using a known method.

When the registered terminal IO makes a call using an off-footer or the like to restart the call waiting service, the calling register 22 is connected in the same way as described above, so when the registered terminal 10 dials, for example, "##4" as a service restart signal, it performs the same procedure as described above. The suspension of the call waiting service for the corresponding registered terminal 10 in the subscriber file 27 is canceled, and the call waiting service is performed when the registered terminal 10 receives an incoming call from now on while the registered terminal 10 is talking.

When the registration terminal 10 performs the operation of transmitting the above-described service stop signal or service restart signal during communication, the registration terminal 10 performs known hooking during communication. The linking information is sent from the subscriber circuit 24 to the call control device 25 via the 5RD 28, and the connection processing section 26 connects the calling register 22 to the subscriber circuit 23. Outgoing register 2
Terminal 2 is connected to registered terminal 1 by a tone signal etc.
0 (not shown), the registered terminal 10 inputs a service stop signal or a service restart signal from the keypad 11 to stop or restart call waiting in the same way as when making a call.

The above is the operation when the call waiting service is stopped between the sending of the service stop signal and the sending of the service restart signal, but then the call waiting service is automatically restarted when the communication that sent the service stop signal ends. The operation in this case will be explained.

When the registered terminal 10 performs communication, if it is desired to stop the call waiting service only during the communication, the keypad 11 is used when making a call or during communication to send out a service stop signal as described above. However, as the service stop signal in this case, a signal different from r##3J in the above example, for example "##5" is used. The service stop signal is sent to the CW control unit 21 via the calling register 22 in exactly the same manner as described above, and the call waiting service of the registered terminal 1° is stopped in the subscriber file 27.

In this state, the registration terminal 10 communicates, but the end of communication is monitored by the subscriber circuit 23 by a known method. When the registered terminal 10 goes on-hook, the joining sound begins! 23
identifies this as the end of communication, and notifies the CW control unit 21 via the connection processing unit 26 of the call control device 25. C.W.
! II? Upon receiving this, the call waiting service of the registered terminal 10 in the subscriber file 27 is released from the stopped state.

In the above description, the service stop signal is sent when a call is made or during communication, but as a modification, it is also possible to send a service stop signal when a call is received. That is, registered terminal 1
By setting 0 in advance, it responds to an incoming call, performs a funking operation, and sends a service stop signal when the calling register 22 is connected to the exchange 20. As a result, the call waiting service is stopped until the communication with the answered incoming call is completed in the same way as described above.

This method is effective when the registration terminal 10 is, for example, an answering machine set to answering mode or a facsimile machine set to automatic call receiving mode. For example, when the registered terminal 10 is an answering machine and the registered subscriber is away, incoming calls are often automatically answered and a message from the caller is recorded. If there is another incoming call while recording, the incoming call notification sound will be added to the message being recorded, which may make it difficult to hear the recorded message. Furthermore, if the registered terminal 10 has a facsimile device and is switched to the automatic facsimile receiving state and receives a facsimile call, the facsimile will be received by automatic response, but if the facsimile is received during facsimile communication, the facsimile will be received. , the incoming call notification sound causes disturbances in the image being received. In the above example, it is desirable to stop the call waiting service when the answering machine is set to the answering state or when the facsimile machine is set to the automatic receiving state, but this can be done by the method described above.

As described above, if the registered terminal 10 sends a service stop signal when making a call or during communication (including when responding to an incoming call), the call waiting service will be stopped until the end of the communication, so important calls and facsimile communication will no longer be interrupted by the incoming call notification sound caused by the call waiting service.

Next, referring to FIG. 3, the operation of stopping the call waiting service, which is the effect of FIG. 2, will be explained. The calling terminal 30 that communicates with the registered terminal 10 is the registered terminal 10.
It is assumed that the registered terminal IO has previously approved that the call waiting service of the terminal IO may be stopped, and that the exchange 20 stores that the terminal is an approved terminal. When the calling terminal 30 communicates with the registered terminal 10, it sends the telephone number of the registered terminal 10 and a service stop signal requesting to stop the call waiting service of the registered terminal 10, for example, r##6. is sent from the key band 31 to the exchange 20. In the exchange 20, when the calling terminal 30 makes a call, the calling register 22 is connected as in a normal call, and receives the telephone number and the service stop signal. At this time, as a method of confirming that the calling terminal 30 is a subscriber authorized to stop the call waiting service of the registered terminal 10, the exchange 20 identifies the accommodation location information of the calling terminal 30. , or by a known method such as having the calling terminal 30 send its own telephone number.

When the calling terminal 30 is confirmed, the calling register 22 transfers the telephone number and the service stop signal to the call control device 25. In the call control device 25, the connection processing unit 26 connects the calling terminal 3
0 to the registered terminal 10, and the CWIIJ control unit 21 stops the call waiting service of the registered terminal 10 in the subscriber file 27. When the registration terminal 10 responds in this state, communication between the calling terminal 30 and the registration terminal 10 starts, but when the communication ends, the subscriber circuit 23 detects this and notifies the call control device 25. This results in
The suspension of the call waiting service of the registered terminal 10 is canceled, and the call waiting service is restarted.

The above example applies, for example, when the calling terminal 30 is an important party to the subscriber of the registered terminal 10 who does not want to be disturbed by the incoming call notification sound during a call, or when the calling terminal 30 is a non-telephone terminal such as a facsimile machine. effective in some cases.

In addition, since the above operation is for the calling terminal 30, which is not a registered subscriber, to stop the call waiting service of the registered terminal 10, the service stop state means that the call waiting service of the registered terminal 10 is stopped by the calling terminal 30 that is not a registered subscriber. In principle, it is limited to. Therefore, as explained above, the call waiting service is automatically restarted when the communication with the calling terminal 30 that sent the service stop signal ends, but when it becomes possible to hear the incoming call notification sound, It is also possible to restart the call waiting service by sending a service restart signal from the calling terminal 30 or the registration terminal 10.

Although the present invention has been explained in detail with reference to FIG. 3 above, FIG. For example, in FIG. 3, the subscriber circuit 23 monitors the end of the communication of the registered terminal 10, but the same effect can be obtained even if the communication is monitored in the trunk 23T after passing through the communication path network 25. It is clear that

In addition, although the connection relationship between the connection processing section 26 and the CW control section 21 in the call control device 25 is omitted in FIG. 3, the configuration is different from the above, including the integration of both, and is explained above. It is easily possible to perform the same effect using a different signal transmission/reception method.

Although FIG. 3 shows an example in which the exchange 20 is a space division (analog) exchange, the exchange 20 is a digital exchange, and the signals from the registration terminal 10 and the calling terminal 30 are digital signals, and the calling register 22 is a digital exchange. It is clear that a digital signal receiving circuit can be substituted to perform the same function. The present invention does not exclude variations in these configurations and signal exchange methods.

〔Effect of the invention〕

As explained above, according to the present invention, a subscriber who has registered a call waiting service or a calling party communicating with the subscriber requests the exchange to stop the call waiting service, and the call waiting service is terminated. This makes it possible to stop non-telephone communications such as important calls and facsimile communications from being interrupted by incoming calls from third parties, thereby increasing the convenience of such call waiting services. It has a remarkable effect on improving sex.
