Abstract

PURPOSE:To report a message, which is desired to be reported from a person to be held in a holding state to a holding person before a talking finish operation, to the holding person when the holding person cancels holding by registering or selecting this message when there is such a message. CONSTITUTION:When hooking is performed at a telephone set 2 while talking between telephone sets 1 and 2, this talking is held, and a holding tone is sent from a holding tone sending device 8 to the telephone set 1. When hooking is performed at the telephone set 1 in such a state, a subscriber circuit 3 is connected to a message registering device 9, and the person to be held registers the message desired to be reported to the holding person. When the holding person performs hooking at the telephone set 2 and holding is released, the message registered on the message registering device 9 is transmitted through a time division switch 5 (link (d)) and a subscriber circuit 4 to the subscriber of the telephone set 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hold release control system capable of releasing a hold by a person to be held in a telephone exchange having a hold function for putting a line in a call on hold according to an instruction from a hold requester. .

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing an example of a conventional telephone exchange having a holding function.

Referring to FIG. 2, the telephone exchange of this example has subscriber circuits 3 and 4 which interface with the telephones 1 and 2 through subscriber lines, a time division switch 5 which accommodates the subscriber circuits 3 and 4, and a telephone. A central processing unit 6 that controls all sequence control of the exchange, and a main storage unit 7 that stores subscriber data and programs executed by the central processing unit 6.
And a holding sound sending device 8 for sending a holding sound to the person to be held under the control of the central processing unit 6.

Next, the operation of this example will be described.

While the telephone 1 and the telephone 2 are in a call through the subscriber circuit 3, the time division switch 5 (link a) and the subscriber circuit 4, for example, the hold person performs a hold operation (hooking) on the telephone 2 to make this call. , The central processing unit 6 controls the time divisional switch 5 to connect the subscriber circuit 3 to the holding tone transmitting unit 8, and the subscriber's telephone 1 has the subscriber circuit 3 and the time divisional switch 5 (link). The hold sound is transmitted from the hold sound sending device 8 through b).

In this state, when the person to be put on hold puts the telephone 1 on the hook and puts it into the call-ending state, the central processing unit 6 detects the call-ending from the subscriber circuit 3 and outputs the hold tone transmitting device 8 and the subscriber circuit 3. The link b between and is disconnected, and at the same time the subscriber circuit 4 is made to send a busy tone to the telephone set 2.

[0007]

In the conventional telephone exchange having the hold function, when the person to be held on-hooks to end the call while in the hold state, the busy tone is sent to the hold person. There was a problem that the message could not be transmitted even if the person on hold had something to tell the person on hold before the end of the call.

[0008]

According to the present invention, in a telephone exchange having a hold function for putting a line in a call on hold in accordance with an instruction from a hold requester, a means for requesting a hold release from a person to be held. A message registration means for registering a message to be sent from the person to be held to the holder at the time of this hold release request, and sending the registered message to the holder when the holder releases the hold state. It is possible to obtain a hold release control method characterized by

Also, a plurality of fixed messages are registered in advance in the telephone exchange, and when the holding person releases the holding state, a desired message is selected from the plurality of fixed messages and the holding is performed. It may be configured to include a message selection unit for sending to a person.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a hold release control system of the present invention.

In FIG. 1, the same components as those of the conventional telephone exchange are designated by the same reference numerals as those in FIG. The telephone exchange according to this embodiment includes subscriber circuits 3 and 4 and a time division switch 5.
A message registering device 9 for sending a message from a person to be held to a person on hold is added to a conventional telephone exchange composed of a central processing unit 6, a main memory 7, and a holding tone sending device 8. The subscriber circuits 3 and 4 each have an LSI configuration having various subscriber control functions (so-called BORSHT function).

Next, the operation of this embodiment will be described.

While the telephones 1 and 2 are calling through the subscriber circuit 3, the time division switch 5 (link a) and the subscriber circuit 4, hooking is performed on the telephone 2 of the holder,
The subscriber circuit 4 detects a momentary interruption of the call current and sends it to the central processing unit 6.

The central processing unit 6 judges that this momentary interruption of the call current is a holding request and controls the time divisional switch 5 to connect the subscriber circuit 3 to the holding sound transmitting unit 8. Hold tone sending device 8
Sends a hold tone to the telephone 1 through the time division switch 5 (link b) and the subscriber circuit 3, and the subscriber of the telephone 1 recognizes that the call is put on hold by the holder (phone 2).

The operation up to this point is similar to the operation in the conventional example.

When the person to be held performs hooking on the telephone 1 in this state, the subscriber circuit 3 detects a momentary interruption of the call current and informs the central processing unit 6.

The central processing unit 6 judges that this momentary interruption of the call current is a hold release request from the person to be held, and the time divisional switch 5
To set the link c between the subscriber circuit 3 and the message registration device 9.

The person to be put on hold sends a message from the telephone 1 to the person on hold, for example, "Hang up the phone for the purpose.
I'll call again later. Or a voice message such as “Hang up. Please call later.” Is registered in the message registration device 9.

In addition, a plurality of fixed messages corresponding to the selected special number are registered in advance in common to all subscribers in the message registration device 9, and the person to be held dials the special number to obtain the desired message. You may make it select.

After the registration of the message or the selection of the message is completed, the held person goes on-hook.

In this state, when the hold person hooks the telephone 2, the hold is released and the telephone call between the telephone 2 and the telephone 1 can be resumed as is generally known. Since it is on-hook, the central processing unit 6 controls the time divisional switch 5 and sets the link d to connect the message registration unit 9 and the subscriber circuit 4.

As a result, the reservation person hears the message addressed to the reservation person from the message registration device 9 registered or selected by the person to be held.

[0023]

As described above, the present invention is provided with the message registration means for registering a message to be sent from the held person to the holding person when the held person requests the holding release, and the holding person is in the holding state. Since the registered message is sent to the holding person when it is released, there is an effect that the message can be transmitted to the holding person even if the held person goes on hook.
