Description

[Detailed Description of the Invention] An unfired tIA is an incoming call from a third party when the subscriber's telephone IIK' is in the middle of a call or communication. The present invention relates to an interrupt communication system that enables communication or telephone conversation between a recipient and a third party.

Figures 1 to 3 are schematic diagrams showing examples of interrupt communication systems that have been proposed in the past. FIG. 4 is a block diagram showing an example of the configuration of the digital telephone shown in FIGS. 1 to 3. Note that FIGS. tjA1 to 4 illustrate a case in which a digital telephone is used to implement a service similar to the call waiting service currently provided to analog telephones.

The details of FIGS. 1 to 4 will be explained next.

That is, in FIGS. 1 to 3, 1 is a signal decoding and generating section, 2 is a communication path switching section, 3 is a holding tone generating section, 4 is a busy tone generating section, M is a multiplied electric motor, and B is a transmitter. Telephone, OFi
3rd telephone, T is the terminal equipment, V is the voice channel, D
8 is a signal channel;
In the figure, 5Fi signal decoder, 6r! audible sound generator,
1 is a signal generator, 8 is a register recall button, 9 is a subscriber line, 10I! i7ykusuiy+, 111: is the transmission line m1ll, 1ffi is the line termination part, 13 is the communication circuit,
14 is a transmitting amplifier, 15 is a receiving amplifier, 1 is a dial, 11 is a transmitter, 18ti receiver, 1 #r! ) - Nringa.

In this case, FIGS. 1 to 3 show a case where a call is received from telephone C to M while telephones M and B are in the middle of a conversation. First, as shown in FIG. , the telephones M and B are connected to the terminal connection terminal 20 shown in FIG. 4 via the voice channel V for communication using the transmitter/receiver 17 and 18 shown in FIG. 4, or via the data channel D. keyboard and display or printer or terminal equipment such as telemail, fax, etc.! When a call is received from telephone 1 0, the colored telephone 5 receives a call ringing tone from signal decoding and generating unit 1 of exchange X via signal channel S. A command signal (code) is sent, this signal is decoded by the signal decoder 5 shown in FIG. 4, and simultaneously with the call or communication with telephone B,
The in-call ringtone generated by the audible sound generator 6 is received! It is given to the i unit 18.

Next, when the user of the telephone who has confirmed the ring tone during a call operates the register recall button 8 of the filling machine, the telephone AO color code generator 7 sends a signal to the signal channel 8.
As shown in FIG. 2, the signal decoding and generating unit 1 of the exchange Switch the communication path by connecting channel D from phone B to 0! 182, puts telephone B on hold, and controls the telephone B to transmit the hold tone from the hold tone generation s3 through the voice channel V. Therefore, the telephone B During a call or during communication, the user of telephone B receives a call and is able to make a call via voice channel V or communicate via data channel D. It becomes something to take.

Then, when the call or communication between the telephone set O and O is finished and the user of the telephone set to be colored presses the register recall button 8 again, the signal generator 7 sends ! through the signal channel 1. - Since the service change signal (code) is sent, as shown in FIG.
1 decodes this signal, 1 cancels the hold of the disconnected terminal B, and controls the communication path switching s2 so that the voice channel V and the data channel D are reconnected from the telephone 0 to the telephone B. 1, by stopping the transmission of the hold tone from the hold tone generation section 3 to the telephone BK, and controlling the busy tone generation section 3 to transmit the busy tone from the busy tone generating section s4 to the telephone OK via the audio channel V. The user goes on-hook.

Therefore, the telephone B can communicate again with the telephone B with which it was initially communicating.

However, according to the above explanation, in the conventional interrupt communication method, if a telephone that is in the middle of a call or is being colored is colored by a third telephone, the register recall button of the colored telephone is operated and the service is serviced. When the change signal is sent, the exchange If you have switched to another phone and are now able to talk or communicate between the called phone and a third phone, the call or communication with the phone that was originally making the call or communication has been forcibly interrupted. This is resulting in cracking.

In addition, if the user receives a call from a third phone and does not want to interrupt the original call or communication after the call is stuttered or colored, the user will not know that the call has arrived from the busy ringtone. However, it is not possible to know who the call is from and what the content is, and it is difficult to know which one should be prioritized, the first call or the call or communication with the third phone. The present invention has the purpose of fundamentally eliminating the drawback of the conventional method, and has the purpose of fundamentally eliminating the drawback of not being able to determine the If the user of the receiving telephone operates the first digitized recall button or the second register recall button according to his/her selection, &, 1 service change signal before #! 2
A Davis change signal is sent, and the switch decodes this signal and changes the data or voice channel to a third
The data channel A- between the third telephone and the called telephone is configured so that the connection is switched to the third telephone and the called telephone while maintaining the telephone call or communication with the telephone that was making the call or overconfidence. Alternatively, the present invention provides an extremely effective interrupt communication method that allows communication or telephone calls to be made via a voice channel.

The present invention will be described in detail below with reference to FIG. 5 showing an actual example.

Figure 5 to 8th W! J is a schematic diagram similar to FIG. 4 to FIG. 3, FIG. In Fig. 9, the same reference numerals as in Figs. 1 to 3 and Fig. 4 indicate corresponding parts, and 1' indicates the solution of the first service change signal (code) and the second t-bis change signal (code). ! 1! Signal decoding conversion with added functions
, 2' can independently switch between voice channel V and data channel D. 1. γ is the first service change signal (code) and the second ′! t is a second register recall button, and 8# is a second register recall button.

In addition, telephone 1. B and 0 are both connected to terminal connection terminals 20 shown in FIG. 4, such as a keyboard, a display, a printer, or a terminal device T such as a telemail machine or a fax machine.

In this case, first, when telephones M and B are talking through the voice channel V using the transmitter/receiver 17 and 18 shown in FIG. If you receive a call, explain that you are busy.

In other words, as shown in FIG.
& continued) From the signal decoding generation unit 1' of exchange X,
Since a call ringing tone generation command signal (code) is sent to the telephone B via the signal channel S, the telephone B decodes this signal using the signal decoder 5 indicated by IK, and transmits the signal to the telephone B. Simultaneously with the call, a ringtone during the call generated by the audible sound generating section 6 is sent to the receiver III. .

When the user of the attached power supply device confirms the ringtone during a call, the user presses the second power recall button V shown in FIG. 9 on the telephone device.
When is operated, a 1'F-bis change signal (code) is sent from the signal generator 1 via the signal channel S,
As shown in FIG. 6, the signal decoding and generating section 1' of the exchange
Controls communication switching 11.1 to switch the connection to #JC.

Therefore, the attached power supply device maintains the telephone conversation via the voice channel V with the telephone C and communicates using the terminal device τ via the data channel D. It can be carried out.

For example, if a keyboard and display are used as the terminal device T, when a key on the keyboard is operated, a code pattern corresponding to the fully operated key is transmitted via the terminal connection terminal 20 shown in Figure 9. is sent out and transmitted to the other party's telephone via data channel D, so that characters and numbers corresponding to the code pattern are displayed on the display via the terminal 20 of the other party's ML machine.

In addition, the communication between the caller and 0 using the terminal device T is completed, and the second terminal recall button V of the double charger
is operated, the signal channel S from the signal generation s7'
A first service change signal (code) is sent via the
As shown in FIG. 7, the signal decoding and generating unit 1' of the exchange
The communication channel switching function is controlled to switch back from aa to B, and the voice channel V is switched from the mid-call sound generating unit 4 to the telephone OK.
In this case, the user of telephone 0 goes on-hook.

Therefore, the telephone M can continue the conversation with B, and can also communicate with the telephone C via the data channel D in the same way.

Next, telephones A and B communicate with each other via data channel D. If overconfidence is being carried out using ``Mk#jA'', if a call is received from the third telephone C to Mk#jA.゛In other words, in this case, as shown in Figure 5, the telephone caller and B are communicating via the data channel D (voice channel V%ABr&jK! = not continuing), but the telephone In response to the incoming call from O, the signal decoding generator Ill' of exchange It decodes and sends the ringing tone during the call to the receiver 1B11.

However, if the user puts the handset 18 on his ear while communicating with the telephone flkB, he will be able to hear the ringtone during the call and use the speaker without knowing that the call is being sent. Adding a function to the r-filling machine, such as making the handset ring with the in-call ring tone and simultaneously lighting up a lamp, etc., in response to the deciphering of the in-call ring tone generation command signal when the in-call ring tone is activated. This allows for easy notification of incoming calls.

When the user of the redundant charger, who has confirmed the coloring during a call, presses the second register recall button V shown in FIG. 2 Davis change signal (code) is sent, so the 8th
As shown in the figure, the signal decoding generation s1' of the exchange
The communication path switching unit τ is controlled to switch the connection to

Therefore, the deposition doubler has secured communication with B via data channel D! Furthermore, it is possible to make a call using the handset 17 and 18 via the telephone 0 and the voice channel V.

When the telephone call between the telephone MU and 0 is completed and the 2nd register recall button V on the telephone MU is operated again, a 1D) is sent to the 2nd service luxury signal from the @ number generation unit γ via the signal channel 8. As shown in FIG. 7, the signal reading generation Ill' of the exchange X decodes this signal, and the communication path switching 11!
2' controls the voice channel master to return the connection from telephone &0 to B, and also controls the busy tone generator 114 to send the busy tone to the telephone SO via the voice channel V. User 0 goes on-hook.

Therefore, telephone 0 can continue to communicate with B, and at the same time can also talk to telephone 0 via voice channel V.

In addition, if there is a possibility that a call is received from the first and third telephone SO while telephones A and B are simultaneously communicating through voice channel V and data channel D, Depending on the judgment of the user of the receiving telephone ^, telephone B
If you are having an important call with
button to temporarily interrupt communication while continuing the conversation with phone B, and communicate with phone 0 using data channel DK. ;- Operate the 'RL button, temporarily interrupt the call while continuing communication with packing machine B, and press the 'RL' button.
A conversation can be made with the i-device 0 using the voice channel V.

Note that if you do not want to interrupt either the call or communication between telephones M and B, you can continue both the call and communication with K without operating any of the register recall buttons. In this case, the in-call ring tone is sent out until telephone 0 abandons the call, so when it is troublesome, the in-call ring tone is generated by the town hearing sound generator 6 in the telephone. Therefore, it is sufficient to add a button and a circuit to stop the transmission of the ringing tone during a call so that the user of the receiving telephone can stop the ringing tone during the call.

In addition, if telephone C receives a call from telephone C while telephone B is in the middle of a call, or if it is okay to interrupt the call with telephone B, or if the user of telephone B displays a color during a call, If you wish to talk to a telephone, you can make a second call with the consent of the user of telephone B, and you may interrupt communication with telephone C. If the user of the telephone MU receives a call during communication and wishes to communicate with the Kyuden Tsumeki, the user of the MU operates the second register recall button C, and communication with the telephone 0 is possible. becomes.

Therefore, depending on the selection made by the user of the deposited double charger, one call (41!0) can be interrupted during a call with B, during an overreach, or during a call and communication at the same time. can.

In addition, if a call is received from telephone C while telephone MU and B are talking, the user of telephone MU operates the 1st register recall button, and at the same time as telephone 1 communicates with B, telephone 1 communicates with 0. In addition, depending on the content of communication with phone C,
When the user of telephone 1aB wishes to make a call to telephone 0, the user of telephone 1aB must obtain consent from the user of telephone 1aB, and then the user of telephone 1aB operates the second register recall button.
Since #f trade is established and the telephone set M can talk and communicate with C, a situation similar to the conventional interrupt overconfidence system can be realized.

Furthermore, after the call between telephone M and 0 ends, if the user of M operates the IK2 register recall button again after the call, telephone M can return to the state of talking with B and communicating with telephone 0. In addition, if the user of the telephone operates the first register call button after finishing fading between the telephone and In addition to this, when telephones M and B are on a call, a call arrives from telephone 0 to M, and the first digital recall button on telephone M is operated. Phone 4! ! Under these conditions, if a call can be received from the fourth telephone to O, the signal decoded by exchange X and generated if! 1' controls the busy tone generating section 4;
Send speech and sound to the telephone. Further, when a call arrives from the telephone set @4 to B or 0, exchange X sends a busy tone to the fourth telephone in order to prevent confusion in the exchange processing during billing processing, etc.

The above theory #JK is obvious) According to the present invention, the telephone &,! ! - If there is a possibility that a call is received from the 1st and 3rd telephone 0 to M while B is in the middle of communication, the second register recall button or the second register recall will be activated depending on the selection by the user of the double charger. When the button was pressed, jlI
A service change number 1N or a second service change signal is sent, and exchange X decodes this signal and switches data channel D or voice channel V from telephone B to telephone O. While communication with B via voice channel V or data channel D is secured, communication with o via data channel D or voice channel M can be carried out.

Therefore, it is possible to make a call to the newly incoming phone without interrupting the call or communication with the phone that was originally conducting the call or Fi communication.
You can find out who the call is from and whether the call is of any kind.

In addition, by pressing the second register recall button O], while maintaining the call with the telephone that was originally making the call,
If the user of the called telephone is in the middle of a call and is communicating with the telephone that received the call, if the user of the called telephone operates the second register recall button, the telephone that was originally making the call will be placed on hold and the call will be continued. You can make a call to the telephone that received the call.

Therefore, the contents of the interrupt communication service in calls and communications for various purposes are improved, and remarkable effects can be obtained.

For example, in addition to using the above-mentioned Digimel telephone, analog telephones that use a P-wave device to divide the transmission frequency band into one for voice and one for signals and data, or for voice data and signal wavebands (e.g. IQ
OKM (above)), and uses an f-wave device to separate voice, data, and signals, or telephones that transmit voice, data, and signals using separate lines, etc., with a data channel and The figure is a block diagram showing a conventional example of a digital telephone, FIGS. 5 to 8Ii are schematic diagrams showing an embodiment of the present invention, and FIG.
