BACKGROUND OF THE INVENTION
The present invention relates to a button telephone apparatus, and more particularly to a button telephone apparatus that temporarily interrupts an original call in response to an interrupt incoming call during a call and forms an interrupted call with a handset different from the original call.
[0002]
[Prior art]
In a general telephone network, when a call is received from another party on the telephone line during a call, a predetermined notification signal is sent to the telephone line to notify the user of a call interrupted call. An interrupt incoming call service (so-called call waiting service) is provided. When this service is used in a button telephone device, an interrupted call may be transferred to a desired handset using general external line transfer. For example, the slave A in a call responds to an incoming call interrupt, listens to the call partner from the interrupt partner, temporarily holds the interrupt call, calls the extension of the call partner B, and interrupts it. Calls can be transferred outside the line.
[0003]
When the interrupted call ends, the user of the slave unit B notifies the user of the slave unit A that the interrupted call has ended, and in response to this notification, the user of the slave unit A makes the original call What is necessary is just to reform. As a notification method, the notification may be made verbally, or the user of the slave unit B may notify the user of the slave unit A through an extension call.
[0004]
[Problems to be solved by the invention]
However, in such a conventional button telephone device, when the interrupt call is ended, the user of the slave unit B indicates that the interrupt call has ended with respect to the user of the slave unit A. Since it is necessary to notify by an extension call, there is a problem that the trouble and operation burden at the end of the interrupt call for the user of the slave unit B increase. Further, if the user of this handset B fails to notify, the original call cannot be recreated in cooperation with the end of the interrupted call, and the destination of the original call held on the network side New incoming call from. When the other handset responds to the incoming call, it is necessary to transfer the incoming call to the handset A, and there is a problem that it is not possible to smoothly shift to the re-formation of the original call.
An object of the present invention is to solve such a problem, and to provide a button telephone device capable of smoothly transitioning from the interruption call termination to the re-formation of the original call without requiring a complicated operation. Yes.
[0005]
[Means for Solving the Problems]
In order to achieve such an object, the button telephone device according to the present invention temporarily interrupts the call by the first slave unit using the telephone line when there is an incoming call interrupted to the telephone line during the call, In the button telephone device that forms a barge call with another second handset using a telephone line, the end of the barge call is notified by calling the first handset in response to the end of the call. An interrupt end notification means is provided, and when the first slave unit does not respond to the call with this interrupt end notification means, a third slave unit different from the first slave unit is called. .
[0006]
In this case, the interrupt end notification means calls the first slave unit for a predetermined period, and if there is no response from the first slave unit, calls the third slave unit different from the first slave unit. May be. As this third handset, a second handset may be selected, or a handset that can normally receive a call may be selected. Further, a plurality of slave units may be selected.
Further, when the third handset responds to the call by the interruption end notification means, the original call by the third handset using the telephone line may be automatically reconfigured.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a button telephone apparatus according to an embodiment of the present invention. In the figure, 1 is a main device connected to one or more telephone lines 11, and 2A to 2N are N (N ≧ 2) slave devices (buttons) connected to the main device 10 via an extension transmission line 3. Telephone).
[0008]
In the main apparatus 1, 12 is an external line I / F unit for terminating and controlling the telephone line 11, 13 is an internal line I / F unit for accommodating the slave units 2 (2 </ b> A to 2 </ b> N) via the internal line transmission line 3, and 14 is an external line I. / F unit 12 and exchange I / F unit 13 are exchange processing units, 15 is a main control unit that controls the entire apparatus, and 16 is a main unit that stores various control information necessary for control by main control unit 15 A storage unit 17 is an information receiving unit that receives various types of information transmitted from the network side via the telephone line 11. The main control unit 15 is provided with a call timer 15A for monitoring the elapsed time of extension calls.
[0009]
The subunit | mobile_unit 2 (2A-2N) has comprised the substantially same structure, 21 is a transmission I / F part which performs data transmission with the main apparatus 1 via the extension line 3, and 22 is a transmission I / F part 21 A speech circuit that decodes the voice data received in step S1 to a voice signal and outputs the voice signal from a handset or a speaker (not shown); encodes voice input from the handset into voice data and outputs the voice data to the transmission I / F unit 21; 23 is a slave unit control unit that controls each unit of the slave unit 2, 24 is an operation input unit that detects operation of various keys such as a hook switch and dial keys, 25 is a display unit that displays various information in characters and symbols, 26 Is a memory for storing control information used for processing of the handset controller 23.
[0010]
In the main storage unit 16 of the main apparatus 1, individual incoming call information including correspondence relationships between each destination number and one or more handset numbers is registered. In the main control unit 15, when an information receiving unit 17 receives a destination number from the network when an incoming call or a call interruption is received, the corresponding slave unit is registered by referring to the individual incoming information in the main storage unit 16. Check if it is. Here, when the slave unit number is registered corresponding to the destination number, the incoming call display is performed only on the slave unit of the slave unit number by individual incoming call processing. If the corresponding handset number is not registered, incoming calls are displayed on all handset.
[0011]
Next, with reference to FIGS. 2 to 5, the operation of the present invention will be described by taking as an example the case where the incoming call during a call is an individual incoming call. FIG. 2 is a flowchart showing call interruption processing (individual incoming call) in the main control unit, and FIG. 3 is a flowchart showing interruption call end processing. 4 and 5 are explanatory diagrams showing call connection states at various points in the flowcharts of FIGS.
First, as shown in FIG. 4 (a), a partner X (4X) connected to the network 4 and a handset A (2A) are connected via a telephone line 11 and a main unit 1, and an external line call 41 Is assumed to have been performed. In this state, when an incoming call 42 is generated from the other party Y (4Y) connected to the network 4 to the telephone line 11, the network 4 is busy on the telephone line 11, so that a predetermined signal is sent to the telephone line 11 To notify the incoming call during a call.
[0012]
In response to this, the main control unit 15 of the main apparatus 1 receives the destination number of the destination Y notified from the network 4 via the telephone line 11 by the information receiving unit 17, and performs the call interruption process of FIG. Start.
First, referring to the individual incoming information in the main storage unit 16, the corresponding slave unit number is acquired, and the incoming call is displayed only to the slave unit corresponding to the slave unit number, for example, the slave unit B (2B) (step 50). . At this time, the other party number may be displayed from the display unit 25 of the slave unit B.
[0013]
As a result, the slave unit B enters a calling state, and in response to a response from the slave unit B (step 51: YES), the main control unit 15 sends a call interrupt response to the slave unit A of the original call on the interrupted side. A standby notification sound indicating that it is waiting is output (step 52).
In response to this, the slave unit A can recognize that an interruption due to an individual incoming call has occurred by outputting a standby notification sound in the state of the external line call 41.
[0014]
Here, when a hold operation is performed in the handset A (step 53: YES), the main control unit 15 controls the exchange processing unit 14 to perform an outside line call on the telephone line 11 as shown in FIG. 41 is put on hold (step 54), and the extension call 43 is placed between handset A and handset B (step 55).
As a result, when the user of the handset A and the handset B has a discussion about the barge call, and the user of the handset A permits the temporary interruption of the external line call 41, the handset A first takes the extension call. Ends 43.
[0015]
In response to the end of the extension call 43 (step 56: YES), the main control unit 15 controls the external line I / F unit 12 to send a hooking signal to the telephone line 11 (step 57). 14 is connected to connect the handset B to the telephone line 11 (step 58).
In the network 4, the external line call 41 on the other party X side is put on hold in the network 4 in response to a hooking signal from the telephone line 11, and the other party Y side is switched and connected to the telephone line 11. Thereby, as shown in FIG.4 (c), the external line call 44 of the other party Y and the subunit | mobile_unit B is formed.
[0016]
Thereafter, when the handset B ends the external line call 44 (step 59: YES), the main control unit 15 performs an interrupt call end process shown in FIG. 3 (step 60).
In the interrupt call termination processing of FIG. 3, first, as shown in FIG. 5 (a), the calling 45 of the handset A that has performed the original external line call 41 is started (step 70), and the calling timer 15A is started. (Step 71).
[0017]
If the handset A responds to this call 45 (step 72: YES), the outside line I / F unit 12 is controlled to send a hooking signal to the telephone line 11 (step 73). In response to this, the network 4 cancels the hold of the destination X and switches and connects the telephone line 11 from the destination Y to the destination X. Further, the main control unit 15 controls the exchange processing unit 14 to connect the telephone line 11 and the handset A (step 74), and returns to FIG. 2 to end a series of call interruption processing.
Thereby, as shown in FIG.5 (b), the original outside line call 41 by the other party X and the subunit | mobile_unit A is reformed.
[0018]
In this way, in response to the end of the interrupting external line call 44, the original handset A is called, and in response to the response operation, the original external line call 41 between the destination X and the handset A is reformed. Therefore, as in the past, for example, in response to the extension call from the slave unit B, the completion of the interrupt call is confirmed, and after the extension call is once ended, the telephone line 11 is recaptured. Need not be performed by the slave unit A, and the original call can be recreated smoothly in cooperation with the end of the interrupt call.
[0019]
On the other hand, when the handset A does not respond in step 72 and the call timer 15A times out after a predetermined period has elapsed since the start of calling the handset A (step 80: YES), as shown in FIG. The main control unit 15 stops the calling 45 of the child device A (step 81), and performs calling of another child device, that is, a call back process on behalf of the child device A.
In this call back process, when any one of the child devices is designated in advance as a call child device (step 82: YES), a call 46 is made to the designated child device (step 83).
[0020]
For example, when the slave unit B is selected as the recall slave unit, the process proceeds to step 73 according to the response of the slave unit B (step 85: YES). Thereby, as shown in FIG.5 (d), the original outside line call 41 by the other party X and the subunit | mobile_unit B is reformed. Therefore, when re-creating the original call after the interruption call ends, if the user of the slave unit A cannot respond to the call to the slave unit A for some reason, the other slave unit is called as a proxy and used. The user is notified of the barge call. As a result, the destination X of the original outside line call 41 is not left unintentionally, and an appropriate call interruption incoming call service can be provided.
[0021]
Further, since the original external line call 41 between the destination X and the slave unit is reconfigured in response to the response operation of the other slave unit that has been called back, for example, the slave unit B It is not necessary to perform complicated operations such as re-capturing the telephone line 11 after confirming the end of the interrupt call in response to the extension call from the terminal, and once the extension call is ended, and linked with the end of the interrupt call. And can recreate the original call smoothly.
[0022]
As the call back device, it is only necessary to specify a handset that the user can always respond to, and the call back device may be specified for each management unit such as the entire key telephone apparatus or extension group. In addition, it is possible to select the slave unit B that has been making an interrupt call instead of a fixed slave unit as the recalling slave unit. In this case, it is expected that there is a user near the slave unit B. Therefore, there is a high probability that the external line call 41 can be recreated in response.
In addition, it is possible to call a handset that can respond to a general normal incoming call that is not an individual incoming call, thereby increasing the possibility of a response. Furthermore, it is possible to call back to a plurality of child devices instead of calling back to one child device, and the possibility of a response becomes higher.
[0023]
In step 82, if a call back handset is not designated (step 82: NO), a handset that can respond to a general normal call that is not an individual call may be called (step 84). . As a result, the call back can be executed reliably regardless of whether or not the call back device is specified, and it is possible to flexibly cope with the case where it differs especially for each management unit.
[0024]
In the above, the case where the interrupted incoming call is an individual incoming call has been described as an example. However, the present invention is not limited to this, and the incoming call interrupted during a call is a normal incoming call not associated with a specific slave unit. The present invention can also be applied to the above, and the same effects as described above can be obtained.
FIG. 6 shows another processing operation up to the transition to the interrupt call.
When a call interruption incoming call is a normal call that is not associated with a specific child device, the call interruption incoming call is not displayed on the other child device, but only to the child device A that is talking on the telephone line 11. Be notified.
[0025]
First, as shown in FIG. 4 (a), when an incoming call during a call is detected while the other party X and the handset A are making an external line call 41 (step 100), The destination number is received by the information receiving unit 17. In handset A, the other party is switched in response to a busy interrupt incoming call display such as a busy interrupt ringing tone from network 4 or a display of the other party number from main apparatus 1 (step 101). As a result, a hooking signal is sent to the telephone line 11, and the network 4 is switched to the partner Y, and an external line call with the handset A is started (step 102).
[0026]
By this outside line call, the user of the handset A confirms the call partner from the destination Y and performs an external line transfer operation to the handset of the call partner, for example, the handset B. Here, the telephone line 11 is put on hold (step 103), an extension call is made from the slave unit A to the slave unit B (step 104), and an extension call is performed in response to the slave unit B (step 105).
In this extension call, the user of the slave unit B is informed that the incoming call is interrupted from the destination Y, and the slave unit A ends the extension call (step 106). The handset B captures the telephone line 11 that is on hold (step 107) and starts an interrupt call with the partner Y (step 108). Then, in response to the end of the interrupt call at the slave unit B (step 109), the process proceeds to the interrupt call end process of FIG. 6 (step 110).
[0027]
If the other party number is displayed from the other party number displayed at the time of a call interruption, the outside line call between the other party Y and the slave unit A is omitted, and the call is made to the slave unit of the call partner, for example, the slave unit B. The middle interrupt incoming call may be transferred outside the line. In this case, instead of steps 101 to 105, operations of steps 120 to 123 are performed. That is, when a call interruption incoming call is detected, an extension button is operated on the slave A to call the extension on the slave B (step 120).
[0028]
In response to this, the main control unit 15 sends a hooking signal to the telephone line 11 (step 121), puts the telephone line 11 on hold (step 122), and makes an extension call in response to the slave unit B (step 123). .
As described above, the present invention can also be applied to the case where the interrupted incoming call during a call is a normal incoming call that is not associated with a specific slave unit, and the same effects as described above can be obtained.
[0029]
【The invention's effect】
As described above, according to the present invention, when there is an incoming call interruption during a call to a telephone line that is in a call, the call by the first handset using the telephone line is temporarily interrupted, and another call using the telephone line is made. In the button telephone device that forms an interrupt call by the second handset, the end of the interrupt call is notified by calling the first handset in response to the end of the interrupt call. It is no longer necessary for the user of the second slave unit to notify the end of the call by verbal or extension call, and the labor and operation burden at the end of the interrupt call to the user of the second slave unit can be greatly reduced. In cooperation with the end of the interrupt call, the end of the interrupt call can be notified to the first slave unit, and the transition from the end of the interrupt call to the re-formation of the original call can be made smoothly.
In addition, when the first handset does not respond to the call, since the third handset different from the first handset is called, by appropriately selecting the third handset, Even if the first handset does not answer, the other third handset is automatically called, and the original call can be reliably reshaped.
