[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a button telephone device, and more particularly, to a button telephone device having a function of responding to an incoming call during an outside line call and a function of receiving and displaying a calling ID notified when an outside line is received.
[0002]
[Prior art]
In general, in a button telephone device that accommodates a plurality of slave units and external lines, the user of the slave unit is in an outgoing call with the other party via the external line, or in response to an incoming call on the external line, If there is an incoming call during a call from a third party via the exchange network, the user of the handset responds to the incoming call during a call by performing a hooking operation and makes a call with the third party. Yes.
[0003]
[Problems to be solved by the invention]
On the other hand, this type of button telephone device has a function to display the calling ID on the slave unit when receiving the calling ID (for example, caller information such as the calling phone number) notified from the switching network to the outside line when the outside line is received. There is something to have. This is to receive a predetermined information signal transmitted from the switching network immediately after the first incoming signal, extract the originating ID from the information signal, and display it on the display unit of the slave unit. As a result, the user can recognize the other party of the caller before answering the incoming call, but this caller ID notification function is also applied to the interrupted incoming call during the above-mentioned outside line call. There is a desire to display the caller ID of an interrupting caller who has made an incoming call during an outside line call on the slave unit.
[0004]
However, even if such a service is realized, the following problems occur. In other words, if an incoming call arrives on the outside line during an external line call with the other party, the destination of this incoming call is not addressed to the external handset that is on the external line, but to another handset connected to the key telephone device. In this case, there was a problem that the caller ID of the caller who made the incoming call cannot be displayed on the other slave unit.
[0005]
Accordingly, the present invention provides a caller of a caller who has made an incoming call even if the incoming call destination handset that has arrived on the outside line during a call is a different handset from the active handset via the external line. An object is to enable display of an ID.
[0006]
[Means for Solving the Problems]
In order to solve such a problem, the present invention provides a button telephone apparatus that accommodates a plurality of slave units and at least one external line connected to an exchange network. When an incoming call is received from the switching network, the first detecting means for detecting the incoming call and the other party information indicating the information of the caller who made the incoming call from the switching network are notified. Receiving means for receiving call destination information, and second detecting means for detecting a predetermined operation of the original call handset indicating the handset during the call after detecting the incoming call by the first detection means When the predetermined operation of the original telephone handset is detected by the second detecting means, an extension call is made to the interrupting telephone handset that performs an interrupt call to the outside line during the call, and the interrupting telephone handset And a control means for transmitting and displaying the called party information to Than it is.
In addition, the control means, after detecting the extension call end operation of the original call handset after the response of the interrupt call handset to the extension call, connects the external line that has received the incoming call to the interrupt call handset. It is.
In addition, the predetermined operation of the original handset includes a response operation for responding to the incoming call and an extension call operation for calling the interrupt handset after responding to the incoming call by the response operation. .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a button telephone apparatus according to the present invention. In the figure, 10 is a main unit connected to one or more telephone lines (hereinafter referred to as external lines) 11 from the switching network 1, and 20A to 20N are two units connected to the main unit 10 via an extension line 30. This is a key telephone (hereinafter referred to as a slave unit).
[0008]
In the main apparatus 10, 12 is an external line I / F unit that controls the termination of the external line 11, 13 is an internal line I / F unit that accommodates the slave units 20 (20 </ b> A to 20 </ b> N) via the internal line transmission path 30, and 17 is an external line I / F unit. An exchange processing unit for exchanging and connecting the F unit 12 and the extension I / F unit 13, 14 a main control unit for controlling the entire apparatus, and 15 for receiving various information transmitted from the switching network 1 side via an external line An information receiving unit 16 is a main storage unit that stores information necessary for control by the main control unit 14. The main storage unit 16 is provided with a buffer 16A for storing partner information for each slave unit 20.
[0009]
On the other hand, the subunit | mobile_unit 20 (20A-20N) has the same structure, 21 is a transmission I / F part which performs data transmission with the main apparatus 10 via the extension line 30, 22 is transmission I / F. A speech circuit that decodes voice data received by the unit 21 into a voice signal and outputs it from a receiver or a speaker, and encodes a voice signal input from the transmitter and outputs it to the transmission I / F unit 21; 20 is a slave unit control unit for controlling each unit, 24 is an operation input unit for detecting operations of various keys such as a hook switch and a dial key, 25 is a display unit for displaying various information, and 26 is a unit for the slave unit control unit 23. It is a memory for storing control information used for processing.
[0010]
In the key telephone apparatus configured as described above, when a user operates the operation input unit 24 of the slave unit 20 to perform an outside line transmission operation, the slave unit control unit 24 detects this and transmits the transmission I / F unit. The transmission operation information is transmitted to the main apparatus 10 via 21. When the main control unit 14 of the main apparatus 10 receives the call operation information via the extension I / F unit 30, the main control unit 14 transmits the call operation information to the external line I / F unit 12 to capture the corresponding external line 11. The dial call information is transmitted to the exchange network 1 via the capture outside line 11 and the exchange processing unit 17 is controlled to connect the call path between the capture outside line 11 and the corresponding slave unit 20. Thus, the other party is called, and when the other party answers, an outside line outgoing call through the user's handset 20 is performed.
[0011]
On the other hand, when the caller makes a call to the button telephone apparatus and an incoming call arrives from the switching network 1 to the external line 11, the main control unit 14 of the main apparatus 14 receives the incoming call via the external line I / F unit 12. Is detected, and the incoming call information is transmitted to the slave unit 20 via the extension I / F unit 13 to call the slave unit 20. In response to this call, when the user of the slave unit 20 operates the operation input unit 24 to perform a response operation, the response operation information is transmitted to the main device 20. When the main control unit 14 of the main apparatus 10 receives the response operation information via the extension I / F unit 30, the main control unit 14 controls the outside line I / F unit 12 to respond to the incoming call outside line 11, and also causes the exchange processing unit 17 to The call path between the incoming call response outside line 11 and the corresponding handset 20 is connected by control. As a result, an incoming call answering call through the user's handset 20 is performed.
[0012]
Here, the button telephone device has a function that allows an external call to the outside line during a call, and the user can connect the switching network 1 during an outside line outgoing call or an incoming call answering call with the other party. In this way, it is possible to receive a call interrupted call from the third party to the outside line 11 during the call. When such a call interruption incoming call is performed, the user responds to the incoming call by performing a hooking operation using the handset 20, and makes a call with a third party.
The button telephone apparatus has a function of notifying the telephone number of the caller (hereinafter referred to as the calling ID) from the switching network 1 when an external line is received, and the calling ID notified from the switching network 1 when the call is received. Is received by the information receiving unit 15 via the corresponding incoming line 11 and the external line I / F unit 12. When the main control unit 14 of the main apparatus 10 inputs the originating ID received by the information receiving unit 15, the main control unit 14 transmits the ID to the slave unit 20 via the extension I / F unit 13 and displays it on the display unit 25 of the slave unit 20. Thus, when an incoming call is received from the outside line, the calling ID is displayed on the handset 20, so that the user can recognize in advance who the phone is from and respond to the incoming call.
[0013]
FIG. 2 is a flowchart showing the first embodiment of the present invention, and shows a response operation for an incoming call during a call when the aforementioned incoming call during a call is made during an outside line call. . Here, in order to distinguish between two calls at the time of call interruption, a call made before the call interruption state is called an original call, and a call that interrupts the original call later is called an interrupt call. And the subunit | mobile_unit which performs the said interruption call is called an interruption telephone subunit | mobile_unit.
In FIG. 2, when a user of the handset 20A performs an outside line call operation and the other party answers, the outside line call is in progress (step S1). Further, when the user of the slave unit 20A responds to the incoming incoming call, the incoming call answering call is in progress (step S1). During an incoming call with such a partner, the caller ID of the partner notified from the switching network 1 at the time of the incoming call is displayed on the display unit 25 of the handset 20A. ID is displayed.
[0014]
When a third party makes a call to the corresponding outside line via the switching network 1 during such an external line call with the other party, the above-mentioned call interruption incoming call is made, and the main control unit 14 of the main apparatus 10 has the external line I. The call interruption incoming call is detected via the / F unit 12 (step S2). The incoming call is sent to the slave unit 20A via the external line I / F unit 12, the exchange processing unit 17, and the extension line I / F unit 13, and is transmitted to the user from the call circuit 22 of the slave unit 20A. Recognizes that there was an incoming call during a call.
[0015]
In addition, when a call is interrupted during a call, the switching network 1 notifies the caller ID of the third party who is the caller, and the main control unit 14 receives the caller ID as call destination information and receives a buffer in the main storage unit 16. 16A is stored (step S3).
On the other hand, when the user of the handset 20A recognizes the incoming call during a call, the user performs a hooking operation using the operation input unit 24 in order to respond to the incoming call. Thereby, a flash signal is transmitted to the main apparatus 10 (step S4). The main control unit 14 that has received the flash signal controls the external line I / F unit 12 to transmit the flash signal from the corresponding external line 11 to the switching network 1 side, thereby interrupting the user of the slave unit 20A during the call. The above-described interrupted call is started with the party (that is, the caller who made the incoming call) (step S5). In this case, the original call described above is put on hold by the switching network 1.
[0016]
Here, when the destination of a call interrupting call recipient is not the child device 20A but the child device 20B (that is, the interrupt call child device), for example, the user of the child device 20A receives the operation input unit 24. A hold operation is performed (step S6). Then, the hold operation information is transmitted to the main device 10 side. When the main control unit 14 of the main apparatus 10 receives the hold operation information, the main control unit 14 controls the exchange processing unit 17 to disconnect the call path between the slave unit 20A and the corresponding external line 11, and also controls the external line I / F unit 12. Then, the interruption call on the corresponding outside line 11 is put on hold (step S7). In this case, the user of the slave unit 20A performs an extension call operation addressed to the slave unit 20B by the operation input unit 24. Then, this extension call operation information is transmitted to the main apparatus 10 side. When the main control unit 14 receives this extension call operation information, it makes an extension call of the handset 20B (step S8). At this time, the main control unit 14 transmits the caller ID of the interrupted caller who has already been received and stored in the buffer 16A of the main storage unit 16 to the slave unit 20B which is the called slave unit, and the display unit 25 Are displayed as call destination information for interrupt incoming calls (step S9).
[0017]
After the extension call to the slave unit 20B is made in this way, when the slave unit 20B side responds to the call, the main control unit 14 controls the exchange processing unit 17 to control the call path between the slave units 20A and 20B. Connect. Thereby, the extension call is started between the slave units 20A and 20B (step S10). In this extension call, after the user of the slave unit 20A, which is the extension calling side slave unit, notifies the user of the slave unit 20B that a call is interrupted during a call, the extension call is terminated using the operation input unit 24. When this is done, the main control unit 14 detects this and performs extension termination processing (step S11). At this time, the main control unit 14 controls the external line I / F unit 12 to cancel the holding of the interrupted call on the corresponding external line 11 and controls the exchange processing unit 17 to control the extension called side slave unit. A call path between a certain handset 20B and the corresponding outside line 11 is connected (step S12). As a result, an interrupt call is performed between the interrupting call recipient on the calling side and the user of the handset 20B, which is the interrupt call slave (step S13).
[0018]
Thereafter, when the user of the slave unit 20B performs the call termination operation, the call path between the corresponding external line 11 and the slave unit 20B is disconnected, and the interrupted call between the interrupting call recipient and the slave unit 20B is terminated ( Along with step S14), by connecting the call path between the child device 20A, which is the original call child device, and the corresponding external line 11, the call with the original partner by the child device 20A is resumed (step S15).
[0019]
In this way, when there is an incoming call on the outside line during an external call of the slave unit 20A, and the slave unit 20A responds to the interrupt incoming call during a call, an interruption occurs between the interrupting call recipient during the call and the slave unit 20A. When a call is made and the destination of the interrupted incoming call is not the original handset 20A, for example, the handset 20B, the interrupted call is put on hold and interrupted by the operation of the original handset 20A. An extension call is made to the handset 20B, which is a handset, and the calling party's caller ID notified from the switching network 1 at the time of the incoming call is sent to the interrupt handset 20B to display the display unit 25. On the other hand, when the extension call end operation by the original call handset 20A is detected after the response to the extension call of the interrupt call handset 20B is detected, between the interrupt recipient and the interrupt call handset 20B So that you can make a barge call with Even if the incoming call receiving device for an incoming call that arrives on an external line is not a mobile device that is calling through the external line, the caller ID of the interrupted callee can be displayed on the called external device. As a result, the user of the destination slave unit can identify in advance who the incoming call is from before the incoming call response, and the usability of the apparatus is improved.
[0020]
Next, FIG. 3 is a flowchart showing a second embodiment of the present invention. Here, since the processes of steps S21 to S25 shown in the flowchart of FIG. 3 are the same as the processes of steps S1 to S5 of the flowchart of FIG. 2, detailed description thereof will be omitted, and will be briefly described below.
That is, in FIG. 3, when an external line outgoing operation is performed by the user of the slave unit 20A and the other party answers, the external line outgoing call is in progress, and when the user of the slave unit 20A responds to the external line incoming call, the incoming call answering call is in progress. (Step S21). When the user of the handset 20A is in an outside line call and a call interrupt incoming call from a third party arrives on this external line, the main control unit 14 of the main device 10 detects the call interrupt incoming call. (Step S22). Further, when such an incoming call is received, the third party's calling ID is notified, and when the main control unit 14 receives this calling ID as the callee information, it stores it in the buffer 16A of the main storage unit 16 (step S23).
[0021]
When the user of handset 20A recognizes the incoming call during a call, in order to respond to the incoming call, the operation input unit 24 performs a hooking operation. Thereby, a flash signal is transmitted to the main apparatus 10 (step S24). The main control unit 14 that has received the flash signal controls the external line I / F unit 12 to transmit the flash signal from the corresponding external line 11 to the switching network 1 side. As a result, the above-described interrupted call is started between the user of handset 20A and the interrupt call recipient (that is, the caller who made the interrupt call) (step S25).
[0022]
Here, when the destination of the call interrupting call recipient is not the slave unit 20A but the slave unit 20B, for example, the user of the slave unit 20A as the original call slave unit performs the first implementation of FIG. Without performing the hold operation as in the embodiment, the operation input unit 24 is used to perform an extension call operation addressed to the handset 20B that is an interrupt call handset. Then, this extension call operation information is transmitted to the main apparatus 10 side. When the main control unit 14 receives this extension call operation information, it makes an extension call to the interrupt call handset 20B (step S26). At this time, the main control unit 14 controls the exchange processing unit 17 to disconnect the call path between the slave unit 20A and the corresponding external line 11, and also controls the external line I / F unit 12 to interrupt the call on the corresponding external line 11. Is suspended (step S27). Further, the main control unit 14 transmits the caller ID of the interrupt callee that has been received and stored in the buffer 16A of the main storage unit 16 to the interrupt call handset 20B that is the called slave unit and displays it on the display unit 25. Then, it is displayed as call destination information for an interrupt incoming call (step S28).
[0023]
After detecting the response to the call on the interrupt call handset 20B side after the extension call to the interrupt call handset 20B is made in this way, the main control unit 14 controls the exchange processing unit 17 to The call path between the original call slave unit 20A and the interrupt call slave unit 20B is connected. As a result, the extension call is started between the original call handset 20A and the interrupt call handset 20B (step S29). In this extension call, after the user of the original call handset 20A, which is the extension caller handset, notifies the user of the interrupt call handset 20B that an incoming call is in progress, the extension call is terminated. If it does, the main control part 14 will detect this and will perform an extension line end process (step S30). At this time, the main control unit 14 controls the external line I / F unit 12 to cancel the holding of the interrupted call on the corresponding external line 11 and controls the exchange processing unit 17 to control the extension called side slave unit. A call path between a certain interrupt handset 20B and the corresponding outside line 11 is connected (step S31). As a result, the interrupt call is performed between the interrupting callee on the calling side and the user of the interrupt call handset 20B (step S32).
[0024]
After that, when the user of the interrupt call handset 20B performs the call closing operation, the main control unit 14 detects this and disconnects the call path between the corresponding outside line 11 and the interrupt call handset 20B. The interrupting call between the incoming caller and the interrupt call handset 20B is terminated (step S33), and the call path between the original call handset 20A and the corresponding external line 11 is connected, whereby the original call handset 20A The call with the original partner is resumed (step S34).
[0025]
In this way, when an incoming call is received on the outside line during an external call of the slave unit 20A, and the slave unit 20A responds to the interrupt incoming call during a call, an interrupt call is made between the interrupt recipient and the slave unit 20A. In the case where the destination of the incoming call is not the original call handset 20A but an interrupt call handset, for example, the handset 20B, the extension addressed to the interrupt call handset 20B by the original call handset 20A. When a call operation is performed, an extension call is made to the interrupt call handset 20B, the interrupt call is put on hold, and the caller ID of the interrupt callee is transmitted to the interrupt call handset 20B for display. When the extension terminal call operation by the original call handset 20A is detected after the handset 20B responds to the extension call, an interrupt call is made between the interrupt call receiver and the interrupt call handset 20B. So, the incoming call arrived on the outside line during the call Even if the receiver's receiver is not a slave that is calling through the external line, the calling party's caller ID can be displayed on the receiver's receiver similarly. This makes it possible to identify in advance who the incoming call is from, and the usability of the apparatus is improved.
[0026]
In the present embodiment, when the original call handset 20A calls the interrupt call handset 20B as an extension, the caller ID of the interrupt callee is displayed on the display unit of the interrupt call handset 20B that is the call forwarding destination. Although it is displayed, it may be displayed when the interrupt handset 20B responds to the extension call.
Further, in the present embodiment, when the original call handset 20A terminates the extension call with the interrupt call handset 20B, the interrupt call hold of the corresponding external line 11 is released and the interrupt call handset that is the call forwarding destination is released. 20B and the interrupting callee are connected, but when the interrupting call handset 20B ends the extension call first, the interrupted call is released from hold, and the original calling handset 20A that is the call forwarding source You may make it connect an interruption call party.
Further, in the present embodiment, the original call handset 20A cancels the hold of the interrupted call at the end of the extension call with the interrupt call handset 20B, and interrupts the interrupt call handset 20B that is the incoming call transfer destination. Although the caller is connected to the caller, the interrupting caller 20B in the extension call and the original caller 20A catches the corresponding outside line 11, thereby canceling the hold of the interrupted call and at the call forwarding source. A certain original handset 20A may be connected to the interrupt callee.
[0027]
【The invention's effect】
As described above, according to the present invention, when an incoming call arrives from an exchange network to an external line during a call by a slave unit, the incoming call is detected and information on a caller who has made an incoming call is obtained. When the destination information is indicated from the exchange network, the destination information is received, and after detecting the incoming call, the predetermined operation of the original handset indicating the handset that is talking is detected. An extension call is made to the interrupt call handset, and the other party's information is sent to the interrupt call handset and displayed. Even if the handset is different from the handset that is in a call, the callee information can be displayed on the destination handset, so that the user of the handset can receive the incoming call. It can be identified before answering the incoming call.
In addition, after detecting the extension call end operation of the original call handset after answering the call to the extension call, the external line that received the incoming call was connected to the interrupt call handset. Even if the incoming cordless handset that arrived on the outside line during a call is not a cordless handset via the external line, the interrupt incoming call was transferred to the called cordless handset and made an incoming call. You can talk to the caller.
In addition, the predetermined operation includes a response operation for responding to the incoming call and an extension call operation for calling the interrupt handset after responding to the incoming call by the response operation. In response to the incoming call, the called child device can be called after confirming the called child device. Therefore, this interrupt incoming call can be accurately transferred to the called child device.
