Description

TECHNICAL FIELD The present invention relates to a method of incoming call interruption to a subscriber who is in a call with an arbitrary party.

[Conventional technology]

FIGS. 3 (a) to 3 (c) are explanatory views showing a conventional telephone interruption receiving method.

FIG. 3 (a) shows a state in which A (subscriber who receives an incoming call interruption) -B (call partner) is in a call. FIG. 3 (b) shows the incoming call detection state in the case where an incoming call arrives at A due to the outgoing call of C (the other party who interrupts) in this state. The subscriber line exchange 1 performs a process of pulling an AB communication path into a CWC (call weighting circuit) 5, and then the CWC circuit sends an IIT (incoming call display tone) 2 to A and A
-B Make a call possible. In addition, the subscriber line exchange 1
Send RBT (ring tone) 3 to C.

Next, FIG. 3 (c) shows a state after the subscriber A who receives the call interruption incoming call makes a hooking (switching instruction signal) to talk with C. The subscriber exchange 1 re-establishes the direct call path between A and C by the switching signal and enables the call, and disconnects CWC5 and at the same time HST (waiting sound) to B.
4 is sent out.

 The above is the conventional telephone interruption receiving method.

[Problems to be solved by the invention]

As can be seen from the above description, when subscriber A calls the interruption sound indicating the incoming call from the second callee who is not known during the call with B, the call to the second callee is unconditionally made. It was switching. That is, the subscriber A has a drawback that at the time of selecting whether to continue the call with the original caller or switch to the second callee, the subscriber A does not yet know who the second callee is. It was

SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-mentioned drawbacks and to provide a telephone interrupting incoming call method capable of selecting whether to switch to the second callee after knowing who the second callee is.

[Means for solving problems]

In order to solve the problem, in the present invention, the exchange is provided with at least a source of an incoming call display sound, a source of a waiting back music sound, a voice response processing unit, a call waiting circuit or a three-way unit.

[Action]

Subscriber A of subscriber line telephone exchange or private telephone exchange
However, when a new incoming call C is made to the subscriber A during a call with an arbitrary call partner B, the exchange detects the fact and the call state between the subscriber A and the call partner B is established. Pull the call path into the call waiting circuit or three-way unit in the exchange,
In addition to the voice of the other party B, the incoming call display sound is sent to the subscriber A to notify that there is a new incoming call C. In response to this, when the subscriber A sends a switching instruction signal by hooking, the call waiting circuit. In response to this, the three-way unit establishes a one-way call path to the other party B, sends back-back music tones through the one-way call path, and sends a new response to the voice response processing section in the exchange. A two-way communication path is provided to the person C and a one-way monitoring communication path is provided to the subscriber A.

Then, while the voice response processing unit sends a voice guidance for guiding the caller's name to the new callee C, when the new callee C announces the caller's name, the conversation contents are described above. The subscriber A is made to monitor through the one-way call path for monitoring, and the subscriber A is returned to the other party B who was in the call until then, or a new callee C is entered.
Let's make a selection.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 (a) to 1 (d), the present invention is applied to a subscriber line exchange 1
It is an explanatory view showing an example when applied to.

It is assumed that subscriber A has a single telephone number and is subscribed to a call interruption incoming call. Subscriber Line Switch 1 is II
T (incoming call display sound) 2, RBT (ringing sound) 3, BGM (waiting chattering sound) 6, and a voice response processing unit 7 that automatically responds to the second callee C by voice and obtains the caller name. , C and a voice response processing section 7 are composed of a CWC (call weighting circuit) 5 for monitoring a call situation.

As shown in FIG. 1 (b), when a new call is received from the second called party C while the subscribers A and B are talking, the subscriber line exchange 1
Detects that event, pulls in the call path in the AB call state shown in FIG. 1 (a) to CWC5, sends the voice of IIT2 and the other party B to subscriber A, and confirms that there is a second incoming call. Inform.

When the subscriber A makes a hooking (switching instruction signal) in order to know the sender name of the second recipient C who does not know who he / she is, the subscriber A shifts to the monitor state as shown in FIG. 1 (c).

At this time, a one-way call path is applied to the other party B who is talking and BG
Send M6. The CWC 5 establishes a bidirectional path to the second callee C and the voice response processing section 7, and at the same time, makes a one-way path to the subscriber A so that the subscriber A can monitor the contents obtained by adding those voice inputs. To be provided. Voice response processing unit 7
When the voice guidance for inducing the caller's name is sent to the second callee C, the second callee C becomes a conversation in which the name is announced in response.

By monitoring the caller name of the second called party C, the subscriber A can select whether to return to the called party B or to enter the call with the second called party C without talking to C.

2 (a) to (d) show the present invention in a subscriber line exchange 1.
It is an explanatory view showing an example when applied to a subscriber line side terminal of.

The subscriber A has a representative number assembled by the subscriber line exchange 1 and has a representative telephone number and a child telephone number, and the subscriber line side terminal is a private branch exchange 10 capable of implementing the telephone interruption receiving method of the present invention.
(The same applies hereinafter) is connected with a pair of parent and child lines. Private branch exchange 10 has IIT (incoming call tone) 2 and RBT
(Ringing tone) 3, BGM (waiting feedback message) 6, and a voice response processing unit 7, C and voice response processing unit 7 for automatically responding to the second callee C by voice and acquiring the caller name. It comprises a TWU (three-way unit) 9 for monitoring the call situation and a common control device 8 for controlling the call path.

As shown in FIG. 2 (b), when subscribers A and B are talking on the parent line and there is a second incoming call on the child line, the private branch exchange 10 detects the event, and FIG. A- shown in a)
The call path in the B call state is pulled into TWU9 and II is given to subscriber A.
The voices of T2 and the other party B are sent to notify that there is a second incoming call.

When subscriber A makes a hooking (switching instruction signal) in order to know the sender name of second recipient C who does not know who he / she is, the subscriber A shifts to the monitor state, as shown in FIG. 2 (c).

At this time, a one-way call path is applied to the other party B who is talking and BG
Send M6. The TWU 9 provides a bidirectional path to the second callee C and the voice response processing section 7, and at the same time, makes a one-way path to the subscriber A so that the subscriber A can monitor the content obtained by adding the voice inputs. To be provided. Voice response processing unit 7
When the voice guidance for inducing the caller's name is sent to the second callee C, the second callee C becomes a conversation in which the name is announced in response.

By monitoring the caller name of the second called party C, the subscriber A can select whether to return to the called party B or to enter the call with the second called party C without talking to C.

The overall control of these processes is performed by the common control device 8.

In the above description, a means for responding by voice to a subscriber who has a telephone having only a call function and notifying the subscriber by voice is used. However, the telephone and the terminal having the multimedia function are used. For subscribers who own
A telephone interruption receiving method having a means for responding with a code signal or a pattern signal and notifying the subscriber by characters can be applied.

〔The invention's effect〕

By using the telephone interruption incoming call method according to the present invention, in the conventional telephone call function, the incoming call display sound due to the incoming call from the second called party C was heard while AB was talking. Since the conversation with the called party C is complicated, it is not possible to return to the call with the first called party B, that is, if the person is hooked, the call with the second called party C is entered and the other party cannot be selected. , There is an advantage that the name of the second called party can be monitored at the time of walking and the calling party can be selected.
