Abstract

The present invention relates to an out-of-office guidance service method for an out-of-electronic exchange for allowing a subscriber who requests a call to a CENTREX subscriber in an electronic exchange, to receive an out-of-office guidance service. If the Centrix subscriber could not answer the call due to a missed call when there was a call request from the outside, the external subscriber heard a ringing sound several times, and then hung up the call again. In the present invention, when a Centrix subscriber registered for the Missing Guidance Service is absent in the electronic switchboard, the subscriber requesting the call to the Centrix Subscriber is provided with the Missing Guidance Service, thereby preventing the caller from making unnecessary phone calls several times. Can To be capable of improving the above-mentioned drawbacks.

Description

Out of service guidance method of electronic exchange

The present invention relates to a missed guidance service method of an electronic switchgear, and in particular, a subscriber requesting a call to a CENTREX subscriber in the electronic switchgear for the absence guidance service of the electronic switchboard for receiving the absence guidance service. It is about.

In this regard, in the related art, when a call request is received from an external CENTRIC subscriber, the CENTRIC subscriber and the external subscriber can make a phone call by receiving the call.

However, in this conventional technique, when a Centrix subscriber is called from an external caller, and the Centrix subscriber cannot receive a call for reasons such as being absent, the external subscriber hears a ringing sound several times and hangs up immediately. There was a drawback of wasting unnecessary time by calling.

The present invention has been made to improve the above-described drawbacks, and if the subscriber to the absentee information registered in the missed guidance service in the electronic exchange is absent, the subscriber requesting the call to the subscribers to receive the absence guidance service It is an object of the present invention to provide a method for the absence guidance of an electronic exchange.

1 is a block diagram showing an embodiment of an electronic switchboard for applying the method of the absence guidance service of the electronic switchboard according to the present invention;

FIG. 2 is a flowchart illustrating an embodiment of a method for providing an out-of-office guidance service for an electronic switch according to FIG. 1.

<Description of Symbols for Main Parts of Drawings>

10: line control subsystem 12: centric line subsystem

14: subscriber line subsystem 16: trunk line subsystem

18: number translation unit 20: Centrix data processing unit

22: input and output unit 24: personal computer

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

1 is a block diagram showing an embodiment of an electronic switchboard for applying the missed guidance service method of the electronic switchboard according to the present invention, wherein a line control subsystem 10 includes an extension subscriber, a general subscriber and a subscriber. It connects incoming subscriber's call into trunk inside the exchange system.

Next, the CENTREX line subsystem 12 performs an exchange service for the Centrix subscribers among the incoming calls from the line control subsystem 10, and the subscriber line subsystem 14 ) Performs a switching service for the general subscriber among the incoming calls from the line control subsystem 10, and the trunk line subsystem 16 relays the trunk line among the incoming calls from the line control subsystem 10. Perform exchange service for incoming subscribers.

In addition, the number translation unit 18 receives the above-mentioned incoming call through the corresponding subsystem, performs the translation of the caller's number, and informs the corresponding subsystem so that the exchange service is properly performed. 20 is sequentially connected via the input / output unit 22 and the personal computer 24, and receives the data related to the Centrix function by the operation of the operator's personal computer 24, and performs appropriate processing to be applied to the exchange system.

FIG. 2 is a flowchart illustrating a step-by-step embodiment of the missed-information service method of an electronic switch according to FIG. It is determined whether (30, 32).

Next, if the missed announcement service function is not activated in the above-described steps 30 and 32, a ring is connected to the extension subscriber so that the caller and the called party can make a call when the extension subscriber answers (34, 36, 38). ).

On the other hand, if the missed guidance service function is activated in the above-described steps (30, 32), the caller sends a guide broadcast notifying the caller that he or she is away to prevent the caller from making an unnecessary call (40).

As described above, according to the present invention, when a Centrix subscriber registered for the Missing Guidance Service is absent in an electronic switchboard, the caller unnecessarily makes a call by allowing the subscriber requesting the call to the Centrix Subscriber to receive the Missing Guidance Service. There is an effect that can be easily prevented from doing several times.

Claims (1)

A first step (30, 32) of judging whether an out-of-office guide service function of the extension subscriber is activated when a call request is made to any Centrix extension subscriber; If the missed announcement service function is not activated in the first step (30, 32), the second step 34 of connecting the ring to the extension subscriber to allow the caller and the called party to make a call when the extension subscriber answers; 36,38); And a third step (40) of transmitting a guide broadcast notifying the caller that the other party is absent when the absence guide service function is activated in the first step (30, 32).
