Abstract

PURPOSE:To realize a camp-on function adapted to actual circumstances, by making it possible that a camp-on registered subscriber selects whether this subscriber should transmit the special tone indicating the existence of a waiting call to a busy subscriber to be camped-on or not in the private branch exchange. CONSTITUTION:When the call from an extension subscriber A comes to an extension subscriber B speaking to an extension subscriber C and the extension subscriber A performs the operation for camp-on registering, a central controller 8 starts a timing generating circuit 10 and monitors hereafter the hooking state of the subscriber A and the detection output of a timing detecting circuit 11 through a scanner 6. A special tone is heard through a device 5 by the subscriber B if off-hook of the subscriber A continues over a certain time; and if the on-hook state of the subscriber A is discriminated within a certain time, the central controller exercises control over the normal camp-on connection without transmitting the special tone to the subscriber B.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a camp-on control system, a camp-on control system VCM in an automatic private branch exchange equipped with a camp-on function.

One of the features of the side automatic private branch exchange is that when a call is received to an extension subscriber who is currently talking, the calling extension subscriber must perform the prescribed operations, then put down the handset and wait. A so-called camp-on function is known that automatically calls a called extension subscriber as soon as the call ends.

FIG. 1 is a diagram showing an example of a conventional camp-on control method for an automatic private branch exchange. In FIG. 1, extension subscribers B and C are connected to communication path 3-1 within network 3.
Connected via and on a call. Kaheru extension subscriber B
An incoming call from another extension subscriber makes an incoming call, and the calling extension subscriber who hears the busy tone returned from the automatic switchboard using a known method, performs a special call for Camp-on registration after, for example, tucking. When the predetermined CampOn registration operation of the township of dialing a number is carried out, the central control device 8 registers extension subscriber Ministry and B as a CampOn registered subscriber and a CampOn registered subscriber, respectively, and handles calls within the network 3. After switching route 3-1 to short-time call route 3-3 and allowing extension subscriber BK to listen to the camp-on callee sound transmitted by the camp-on callee sound transmitter 5, the call route 3-1 is changed again to call route 3-3. 1 to continue the conversation with extension subscriber C.

At the same time, the central controller 8 connects the communication path 3- to the network 3.
2, and the camp-on registration sound transmitted by the camp-on registration sound sending device 4 is transmitted to the extension subscriber AKI11. The elderly extension subscriber who heard the Camp On registration sound knew that he had been registered as a Camp On registrant, and put down his handset and waited, and the extension subscriber B, who heard the Camp On registration sound for a short time, made a call. When an incoming call occurs during the call, the subscriber learns that he has been registered as a camp-on subscriber, and ends the call with extension subscriber C early. The central control unit 8 detects the termination of the extension subscriber B's call and connects the subscriber circuits 2-1 and 2.
-2 is controlled to send the extension subscriber ^ and BK calling signals, and after the response, a communication path 3-4 within the network 3 is set to enable the extension subscriber ^ and B to talk.

As is clear from the above explanation, in the conventional camp-on control system, when extension subscriber A executes a predetermined camp-on registration operation, extension subscriber B#IC is unconditionally delivered a camp-on registered sound. This results in prompting early termination of the call with extension subscriber C. The built-in subscriber AK has no choice but to allow the internal subscriber BK to listen to the camp-on sounds if necessary.

An object of the present invention is to eliminate the drawbacks of the conventional camp-on control method as described above, and to enable registered camp-on subscribers to send camp-on registered sounds to returning camp-on subscribers.
! This is a camp-on control method that allows you to select which songs to listen to depending on the situation.

This purpose is to provide an automatic private branch exchange equipped with a camp-on function with a timer for detecting the elapse of a predetermined time in a camp-on registered sound sending device that sends out a camp-on registered subscriber's KdP jump-on climbing sound, and to When the time measuring means activated at the start of transmitting the on-registered sound detects that the predetermined time has elapsed and also detects that the camp-on registered subscriber continues to be in an off-hook state, the camp-on registered subscriber joins. This is achieved by delivering the camp-on registered sound to the person.

An embodiment of the present invention will be described below with reference to FIG. Figure 2 is part 1 of the present invention! FIG. 3 is a diagram illustrating a camp-on control method based on Note that the same reference numerals indicate the same objects throughout the figures. The difference between FIG. 2 and FIG. 4 is that the camp-on registration sound sending device 4 is provided with a timing generation circuit 10 that detects the passage of time, and a timing detection circuit 11 that detects that a predetermined time has elapsed. It is in the point where it is. Similar to FIG. 1, in FIG. 2, communication path 3-1 in network 3
When a call issued by extension subscriber BIIC extension subscriber A, who is currently talking to extension subscriber C via Subscribers A and B are registered as Camp-on registered subscribers and Camp-on registered Kama subscribers, respectively, and a call path 3-2 is set up in the network 3 to allow extension subscriber Am to listen to Camp-on subscriber sounds. 1 timing generation circuit 1O is started, and from then on, the extension subscriber saving state and the timing detection circuit 1! , are monitored via the scanning device 6. Timing generation circuit 1
When the timing detection circuit 11 detects that the predetermined time has elapsed after G starts, it sends a detection output to the scanning device 6.

When the central control device 8 receives the detection output via the scanning device 6, the central control device 8 identifies that the extension subscriber elderly who is a registered camp-on subscriber continues to be in an off-hook state. The communication path 3-1 is switched to the communication path 3-3 for a short time (for example, 1 second or less), and during that time, the camp-on subscriber's sound transmission device 5 is transmitted to the extension subscriber B who is the camp-on subscriber. At the same time, the timing generation circuit 1
Stop 0. Extension subscriber B learns of the existence of the incoming call for the first time and ends the call with four-line subscriber C early. On the other hand, the central control device 8 detects the on-footer of the extension subscriber before receiving the detection output of the tie-up detection circuit 11, and stops the timing generation circuit 10 to release the call jl 13-2 in the network 3. The central control device 8 connects the communication path 3-1 within the network 3 to s-3.
Since there is no KMIR support, extension subscriber B does not listen to the camp-on registered sound transmitted by the camp-on registered sound transmitting device 5, and becomes aware of the existence of the incoming call while talking. The call with extension subscriber C is immediately terminated. In either case, the central control unit 8 detecting the termination of the call of extension subscriber B carries out extension processing and Bf) connection processing using a known method.

As is clear from the above explanation, according to the present example, the subscriber who subscribes to the extension is asked whether or not extension subscriber B puts down the handset within a predetermined time after registering for Camp On. You can choose whether or not to listen to the registered sound.

It should be noted that FIG. 2 is only one embodiment of the present invention, and for example, the means for measuring a predetermined time provided in the camp-on registration sound sending device 4 is limited to the timing generation circuit 10 and the timing detection circuit 111. There are many other things, such as depending on the program! Although current means are considered, the effects of the present invention do not change in either case. Furthermore, if extension subscriber A continues the off-hook state until a predetermined period of time has elapsed after the camp-on operation, extension subscriber B who has heard the middle jump-on tone will end the call with extension subscriber C. It is not limited to ending the call early, but it is also possible to use a so-called call waiting function in which the call with extension subscriber C is temporarily put on hold and the extension subscriber responds with an AK by performing 7-talking. It goes without saying that the effects of the present invention will not change even if the structure is changed, and that the structure of the automatic private branch exchange to which the present invention is applied is not limited to that shown in the drawings.

As described above, according to Honjimeikaku, in an automatic private branch exchange equipped with a camp-on function, a camp-on registered subscriber makes a camp-on registered subscriber who is on a call listen to the camp-on registered tone, It becomes possible to freely choose whether or not to make the presence known, and it becomes possible to realize a camp-on function that suits the actual situation.
