BACKGROUND OF THE INVENTION
The present invention relates to a button telephone apparatus, and more particularly to a button telephone apparatus that utilizes a call interruption incoming call service provided from a network.
[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 using this service with a button telephone device, for example, by performing a hooking operation in response to an incoming call interruption, the call destination is held on the network side, and the interrupt destination is switched and connected. You can start a call with the other party. Then, according to the subsequent hooking operation, either the interrupt partner or the original partner can be switched and selected alternately. In addition, by using the outside line transfer function, it is possible to form an interrupt call between a slave unit other than the slave unit of the original call and the interrupt partner.
[0003]
[Problems to be solved by the invention]
However, in such a conventional key telephone device, the user can switch the call by using the switching selection of the other party or the outside line transfer function by the hooking operation by the user, but this is not managed by the key telephone device itself. There is a problem that the user himself / herself has to memorize and cannot use the incoming call interruption service smoothly without any burden. For example, if another cordless handset responds to an incoming call interrupted to the telephone line held by the main unit and initiates a barge call, even if you want to resume the call on the cordless handset, Had to wait until the talk was over.
An object of the present invention is to solve such a problem, and an object of the present invention is to provide a telephone device that allows a user to smoothly use a call interruption incoming call service without feeling much of an operation burden.
[0004]
[Means for Solving the Problems]
In order to achieve such an object, a button telephone device according to the present invention includes a plurality of slave units including at least first and second slave units, and a main unit connected to a telephone line and controlling each of the slave units. A button telephone device that forms a barge call using the telephone line when a call is interrupted from the network side for a telephone line that is in a call, and detects that a call is interrupted during a call And a slave unit other than the first slave unit when the detection unit detects that a call interruption during a call to the telephone line held by the main unit in response to a hold operation of the first slave unit is detected Call forming means for forming an external line call between the other party on the call interrupt side and the second slave unit in response to an operation of responding to the call by the second slave unit. Provided by the calling means , Depending on the re-response operation to the telephone line by the first slave unit in outside call, in which to perform a call during the call to the second handset.
[0005]
For a call during a call, a voice call interruption from the first slave unit may be formed for the second slave unit during an external call. In addition, the call forming means determines whether the first caller and the other party of the original call held on the network side are in response to the call termination operation of the external call by the second caller after the call is started during the call. An external line call may be formed.

[0010]
Next, a processing operation according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a flowchart showing call interruption end processing in the main control unit, and FIG. 4 is a timing chart showing an example of call interruption end processing in FIG.
FIG. 3 is an explanatory diagram showing the connection state between the key telephone apparatus used in the call interruption process of FIG. 2 and the network side. In the following, the destination X (4X) and the destination Y (4Y) are connected to the network 4. It is assumed that the network 4 and the main device 1 are connected via the telephone line 11A, and the child device A (2A) and the child device B (2B) are connected to the main device 1.
[0011]
First, as shown in FIG. 4, before the time T ₁ , an external line call 41 is performed between the slave unit A and the destination X via the network 4, the telephone line 11 A, and the main device 1. At time T _1, when the external hold operation is performed by the slave unit A, the main control unit 15, to hold the telephone line 11A controls the exchange processing unit 14. Thereby, the other party X becomes a holding state in the main device 1, and the slave unit A shifts to an idle state (unused state) in response to an on-hook operation. In this state, if the external line call 42 to the telephone line 11A from the destination Y in time T _2, is performed, since the network 4 is the phone line 11A is a call, the telephone line 11A a predetermined signal Send out and notify the incoming call during a call.
[0012]
In the main control unit 15 of the main apparatus 1, the telephone line 11 </ b> A is on hold in the main apparatus 1 in response to an incoming call interruption from the network 4 detected by the information reception unit 17 (detection means). Then, a call 43 is made to the handset that can respond to the incoming call to the telephone line 11A among the handset 2A-2M. In this call 43, it is displayed that the incoming call is an interrupted call while being identified as a general incoming call. Further, information indicating a telephone line (telephone line 11A) where an interrupted incoming call during a call has occurred, and information indicating a slave unit (slave unit A) holding the telephone line may be displayed.
[0013]
When a slave unit other than the slave unit A, for example, the slave unit B responds to the call 43 from the time T ₂ (time T ₃ ), the main control unit 15 controls the exchange processing unit 14 to hold the telephone line 11A. Is released, a hooking signal (switching signal) is sent to the telephone line 11A, and the telephone line 11A and the slave unit B are connected (call forming means).
In network 4, in response to a hooking signal from telephone line 11A, destination X is put on hold in network 4 and destination Y is exchange-connected to telephone line 11A. Thereby, an outside line call (interrupt call) 44 between the destination Y and the slave unit B is formed.
[0014]
In response to the formation of the external line call 44, the main control unit 15 starts the call interruption process of FIG.
First, call loop processing is started in steps 100 and 110. In this call loop processing, when a re-response (hold release) operation to the telephone line 11A is performed at time T ₄ in the hold handset A, here the handset A that previously held the other party X (step 100: YES) The main control unit 15 calls the handset B that is talking on the telephone line 11A from the handset A, and forms a voice call interruption 45 here (step 101: calling means).
[0015]
Thereby, the user of the slave unit A notifies the user of the slave unit B that he / she wants to resume the call with the destination X. In response to this, when the handset B ends the external line call 44 with the partner Y at time T ₅ (step 102), the main control unit 15 sends a hooking signal to the telephone line 11A (step 103). Then, the exchange processing unit 14 is controlled to connect the telephone line 11A and the slave unit A (step 104: call forming means).
In the network 4, in response to the hooking signal, the destination X that has been put on hold is switched and connected to the telephone line 11A. Thereby, the outside line call 46 between the other party X and the slave unit A is resumed.
[0016]
In this way, the handset B other than the handset A holding the telephone line responds to the interrupted incoming call on the telephone line 11A that is on hold to form an interrupted call, and the handset A during the interrupted call is formed. In response to the re-response operation at, a call during a call is made to handset B, so that handset A can re-send to the on-hold telephone line and can be held by hand of handset A. In response to operations in response to a series of responses, the handset for barge calls is automatically notified that it wants to resume the call, so the call interrupt call receiving service can be provided without the user feeling much of the operation burden. It can be used smoothly.
[0017]
Since the call interruption 45 by the voice of the user of the slave unit A is formed as a call during the call from the slave unit A to the slave unit B, the call from the user of the slave unit A to the slave unit of the interrupt call is resumed. It is possible to convey to the user of handset B accurately by voice. As a call during a call from the slave unit A to the slave unit B, a three-party call in which the slave unit A directly interrupts the external line call 44 between the slave unit B and the destination Y may be formed. Alternatively, a voice call for outputting voice from the speaker of the slave unit B may be formed. Furthermore, the present invention is not limited to voice call interruption, and a ringing sound or information display indicating that a call resumption is desired may be output to the slave unit B.
[0018]
Furthermore, after the call during the call from the slave unit A to the slave unit B is started, in response to the call termination operation of the external line call by the slave unit B during the call, the destination X and the child of the original call held on the network side Since the external call with the device A is automatically formed, the user of the slave device A can shift to the call resumption without performing a complicated operation.
[0019]
In the above-described call loop processing, a communication handset that is making an external line call 44 with the other party X. Here, when a call end operation is performed at the handset B, as shown in FIG. Here, a hold alarm may be output to the handset A. In this case, in response to the call termination operation at the handset B at time T ₆ (step 110: YES), the main control unit 15 sends a hooking signal to the telephone line 11A (step 111) and the exchange processing unit 14 To hold the telephone line 11A (step 112). Then, a hold alarm 47 is output to the child device A (step 113).
[0020]
In the network 4, in response to the hooking signal, the destination X that has been put on hold is switched and connected to the telephone line 11A. As a result, the destination X is put on hold in the main device 1 and if a re-response operation is performed on the slave A at time T ₇ in response to the hold alarm 47, the external call 48 between the slave A and the counterpart X Is reformed.
In this way, the slave of the original call is automatically notified that the interrupted call has been terminated, and the user can smoothly use the interrupt incoming call service without feeling the burden of operation.
[0021]
【The invention's effect】
As described above, according to the present invention, a second slave unit other than the first slave unit that calls a predetermined slave unit in response to the detection of a call interruption interrupt on the held telephone line and holds the telephone line is provided. In response to a call response operation by the slave unit, there is provided a call forming means for forming an external line call between the other party on the call interrupt side and the second slave unit, and the first slave unit during the external line call is provided. In response to the re-response operation to the telephone line, the call to the second handset is made during a call. Therefore, the first handset can perform a simple operation of re-answering the hold telephone line and the first handset. The user of the slave unit is automatically notified that the caller wants to resume the call to the slave unit of the interrupted call according to the operation along the sequence of hold → re-response. Smoothly use the incoming call interrupt service without feeling Kill.
