JPS5944162A - Response system in talking - Google Patents

Abstract

PURPOSE:To attain instantaneous response even if a subscriber originally desired to talk with is talking with aother subscriber by entering a call terminated to another telephone set during talking to a self-talking circuit. CONSTITUTION:During the talking (a) between subscribers A and B, a call is terminated from a subscriber C originally desiring to talk with the subscriber B and a subscriber D responds (e) to the call and informs the call (C) from the subscriber C to the subscriber B. If the subscriber B hooks, the hooking operation is discriminated by an IOT rear side monitoring circuit IOT-R, a scanning circuit SCN and a control circuit, a connection command to a trunk ORT is set to a network NW through a channel control device and the subscriber A is held (b). Dialing the specified No. of the subscriber B + the number of the subscriber D enables the subscribers B and C to talk with each other (c) and then the subscriber B can talk with also the holding subscriber A by hooking operation in a call waiting state. Disconnecting (d) the subscribers A and C causes a state (h).

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Portion of the Invention IMf The present invention relates to a service system for an electronic private branch exchange, and particularly relates to a mid-call response system for drawing other busy calls to the own call line.

(2) Prior art and problems Conventionally, when a subscriber who is currently talking receives a call on another telephone, that subscriber temporarily interrupts or disconnects the call and goes to the telephone that received the call. Otherwise, the incoming call is generally disconnected because the call is in progress, or the subscriber is asked to wait until the call ends.

Therefore, after the call is over, the user must either wait for the call to come in again or dial the number themselves to make the call, which is a problem for busy people or situations where a quick response is required. becomes very complicated. Furthermore, if the subscriber is asked to wait until the end of the call, the incoming call cutter will be used exclusively for that purpose and no other calls can be made or received, causing problems such as interruption of exchange services for other subscribers. .

(3) Purpose of the Invention The present invention eliminates the above-mentioned drawbacks, by providing a call to a subscriber who is on a call, after receiving an incoming call on another telephone and answering the call, the incoming call is transferred to the line where the call is being made. To provide a 6-in-6 response system that enables an immediate response even when the person you originally want to talk to is talking on another telephone.

(4) Structure of the Invention In order to achieve the above object, the present invention provides that, in an electronic private branch exchange, when a first subscriber is busy talking, an means for pulling the λf call into the active line of the first subscriber, and when the first subscriber receives a λf call to be terminated, the means enables the first subscriber to communicate with the incoming call. characterized in that the means for connecting to the line in use is r4f lr after hooking.
+e4'r 2 subscriber number" by dialing the characteristic number.

(5) Examples of the invention The present invention will be explained below in detail by way of examples.

FIG. 1 is a system configuration diagram for realizing the present invention, and FIG. 2 is a diagram showing a control procedure of the present invention. In Fig. 1, there are subscriber telephones in the switching network (communication route network) NW, H, C, and D (for internal communication).
OT, outgoing register trunk ORT, etc. are connected. Scanning circuit LSC from each telephone and trunk
N, TSCN, is connected to the control device CC via the communication path control device 5PCE.

Note that MM is a memory.

Based on this configuration, the in-call response system of the present invention will be explained using FIG.

In FIG. 2, (a) shows a state in which subscribers A and B are connected to their own intra-office trunk 10T (IOT-F indicates the frometo side, IOT-R indicates the rear side) and are talking.

On the other hand, Figure (E) shows a state in which a call has been received from subscriber C to subscriber C, and subscriber C has responded. Here, it is assumed that the incoming call (C1) was originally intended to be received by subscriber B.

Subscriber 1 notifies subscriber B that there is an incoming call (C).

Then, when subscriber B performs a hooking operation, the hooking information is detected by the rear monitoring circuit of the IOT, and the control 1 device CC recognizes it via the scanning circuit SCN, and sends the originating register trunk ORr connection command via the 5PCE. The subscriber A is sent to the NW and placed on hold (Figure (B)). The process up to this point is similar to the control of services such as well-known consultation hold. In the present invention, next, in the state shown in (b), dial [Special inquiry + subscriber number 1) where the call was received. do.

When the control device CC recognizes this dialing information via the scanning circuit TSCN, it indexes the memory based on the subscriber number and extracts information about the call status of the subscriber shown in the figure. Then, subscriber B and subscriber C are set to another IOT and are placed on the phone (see Figure (C)), and subscriber B and C are released. (Figure 1) Thereafter, subscriber B can talk to subscriber A who is on hold by a hooking operation, and becomes able to talk to subscriber C by hooking again, which is a known call waiting state. That is, due to the disconnection operation of subscribers A to C, respectively,
The situation will be as shown in Figure 2) and Figure 2).

A. The present invention is a split call system in which subscriber B is connected only to either subscriber A or C, and the state is not changed to a three-party call state via B.

In this embodiment, mutual extensions have been described, but the present invention is also applicable to the case where the incoming call is 7'+rM.
Even in that case, the effects of the present invention remain unchanged.

Also, when you need a king call, use the "
By separately setting a special number, it is also possible to implement the system according to the subscriber's choice.

In addition, as an application example, if another call interrupts during a call, the call can be transferred to another extension (contrary to the present invention, the call is separated), which can also be used as a control function. Dechiru.

(6) As described in detail, according to the present invention, even if an incoming call is received on another telephone during a call, the call can be routed to the own telephone line, and the service can be terminated. This will greatly contribute to the improvement of
