DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange system, and more particularly to a method and an apparatus for connecting an interrupt call.

[0002]

2. Description of the Related Art FIG. 2 is a connection diagram of an interrupt communication connection device in a conventional telephone exchange system.

Conventionally, this type of interrupt call connection method is:
In the case where the subscriber 2 is a registered subscriber of the interrupt call service, when a third party subscriber 4 originates a call with the subscriber 2 as a destination during a call with the subscriber 3, the exchange 2 If the call is busy, the outgoing call is connected to the interrupt call trunk 15, and an interrupt call is transmitted to the called party 2 while the line being held is held, thereby notifying that there is an interrupt call. The subscriber 4 is made to ring.

When the destination subscriber 2 informs the subscriber 3 that he / she will answer the interrupt call and then hooks up, the interrupt call trunk 15 holds the connection of the subscribers 2 and 3 by the exchange switch 1 while holding the connection. Exchange switch 1 for subscriber 4
Is connected to the subscriber 2 via a telephone, and a call can be made. afterwards,
When the subscriber 2 ends the call with the subscriber 4 and hooks, the interrupt call trunk 15 disconnects the subscriber 4 and restores the connection with the subscriber 3 held by the exchange switch to the callable state. I do.

[0005]

In the above-described conventional method of connecting to an interrupt call in a switching system, since the called subscriber does not know the contents of the interrupt call at all and does not hook up a response to the interrupt call without calling the other party, the call is interrupted. There is a drawback that if the call is interrupted as an urgent important call, it cannot be contacted.

An object of the present invention is to provide a method and an apparatus for connecting an interruption call of an exchange, which can notify the gist of the call so that the interruption call is not ignored when the interruption call occurs.

[0007]

SUMMARY OF THE INVENTION In an interrupt call connection method for a telephone exchange, when an incoming call to a subscriber registered for an interrupt service is encountered while the called party is busy, the caller is told the call summary of the incoming call and speaks. Storing and interrupting the stored call summary to the called party's busy line
And announcing to the called subscriber .

Also, the step of announcing to the called subscriber includes assigning to the called subscriber during a call.
Interrupt the write trunk, connected to interrupt sound, its
It has a step of connecting the announcement of the subject matter of the voice stored interrupt call following the record is a preferred embodiment of the interrupt call connection of the telephone exchange of the present invention.

[0009] The interruption call connecting device of the telephone exchange according to the present invention, when an incoming call to a subscriber registered for interruption service is encountered while the called subscriber is busy, allows the originator of the call to speak the point of the call. Means for making a guidance announcement, means for accumulating the voice of a call spoken by the caller of the incoming call in accordance with the announcement, and interruption of the called party during the call by an interrupt trunk.
And means for connecting an interrupt call sound and subsequently announcing the voice-stored summary.

[0010]

[Action] Since the call summary of the interrupted call is stored in voice and announced to the called party at the time of the interrupt notification, the called party can recognize the gist of the interrupted call and decide to start the answering operation. be able to.

[0011]

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

FIG. 1 is a connection diagram of an apparatus to which an interrupt call connection method for an exchange according to the present invention is applied.

This device comprises an interrupt call trunk 5;
It comprises a voice storage / reproduction device 6 and a guidance announcement unit 7, and cooperates with the exchange switch 1.

The interrupt call trunk 5 holds the interrupt call and first connects to the guidance announcement unit 7.
The guidance announcement unit 7 makes a guidance announcement so as to speak the call summary of the interrupt call or a simple message. When the requester of the interrupted call speaks the gist of the call according to the guidance, the voice storage / reproduction device 6 stores the voice. When the voice storage is completed, the interrupt call trunk 5 interrupts the call of the called party 2 via the exchange switch 1 and sends an interrupt call sound, and then summarizes the stored call call of the interrupter. Play and announce. The interrupt call trunk 5 repeats the announcement a predetermined number of times, and if there is no response by hooking, announces the fact to the interrupt call requester and disconnects the call. If there is hooking, the interrupt call trunk 5 connects the interrupt call to the subscriber 2 as before.

Next, the operation of this embodiment will be described.

Suppose that subscriber 2 is an interrupt service registered subscriber and is currently busy with subscriber 3. During this call, when the subscriber 4 originates a call with the subscriber 2 as a destination, the receiving exchange performs a busy test on the subscriber 2 and, when confirming that the subscriber 2 is busy, switches the incoming call to the exchange switch 1. To the call trunk 5 via an interrupt.

The interrupt call trunk 5 holds the connected incoming call, connects to the guidance announcement unit 7,
The subscriber 4 is made to speak the point of the call, and the voice is stored in the voice storage / reproduction device 6. When the voice storage is completed, the interrupt call trunk 5 interrupts the subscriber 2 to send out an interrupt sound, and subsequently reproduces and announces the stored call point. When the subscriber 2 hooks, the connection with the subscriber 3 during the call is suspended, and the incoming call is connected to the subscriber 2 from the interrupt call trunk 5 via the exchange switch 1.

When the subscriber 2 ends the call with the subscriber 4 and hooks, the interrupt call trunk 5 is switched to the subscriber 4
Then, the connection with the subscriber 3 is cut off, and the connection with the subscriber 3 that has been held can be communicated and restored.

[0019]

As described above, according to the present invention, when an interrupt tone is sent to the called subscriber, the gist of the interrupted call or a simple message is announced to the called subscriber. This makes it possible to grasp the contents of the interrupted call and to determine the reception of the interrupted call accurately and promptly.
