Description

Conference call service method in exchange

The present invention relates to a method of a conference call service in an exchange, and more particularly, a conference call having a function of allowing a master subscriber to make a single call with one of slave subscribers during a conference call. It relates to a service method.

The conference call service in the exchange is a service that allows three or more subscribers to conduct a call at the same time. The call is divided into a master subscriber and a slave subscriber. That is, only one subscriber is set as a master subscriber and the other subscribers are set as slave subscribers when the call proceeds using the conference call service. However, during the conference call service, there is a problem that the master subscriber cannot make a 1: 1 call alone with one of a plurality of slave subscribers connected to a speech path.

Accordingly, an object of the present invention is to provide a conference call service method having a function of allowing a master subscriber to perform a single call with one of slave subscribers during a conference call service in an exchange.

In order to achieve the above object, in the conference call service method according to the present invention, when a predetermined subscriber's telephone is hook flashed, a specific dial tone is connected to a predetermined subscriber, and a hold tone is set to a subscriber telephone set as a slave subscriber for a conference call. A first checking step of checking whether a predetermined subscriber is a conference call service registered subscriber and a master subscriber; and as a result of performing the first check step, if the predetermined subscriber is a conference call service registered subscriber and a master subscriber, the predetermined subscriber dials. Receiving a called party number; A second checking step of checking whether the called party number is equal to the number of slave subscribers; If the check result of the second check step is not the same, reconstructing the conference call path to include a corresponding subscriber and proceeding with the conference call; after performing the call reconstruction step, if a hook flash is generated from the master subscriber Conducting a conference call using the reconstructed communication path; if the result of the check in the second check step, disconnects the hold tone provided to the corresponding slave subscriber and forms a single communication path with the master subscriber to conduct the call; And if a hook flash is generated from the master subscriber during the exclusive call, returning to the conference call progress state before the exclusive call.

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, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram in an exchange capable of performing a method of a conference call service according to the present invention, which is referred to as a line processor (100, hereinafter referred to as a line processor) for matching processing with a domestic subscriber. And the main processor 110 (hereinafter referred to as MP) for performing a matching process with the LP 100, a matching process with a trunk not shown, and other control functions for call processing.

The MP 110 includes Subscriber Call Control, System Status Control, Call Register Handling, Attendant Call Control, and Centrex Call Processing. Subscriber line subsystem (111, hereinafter referred to as Subscriber Line Subsytem) which performs control, number translation, time switch, telephony device control and subscriber data matching And a switch control and number translation unit 112 (hereinafter abbreviated as Switching Number Translation Subsytem) for subscriber data handling processing.

2 is a flowchart illustrating a conference call service method according to the present invention.

Next, the flowchart of FIG. 2 will be described in detail with reference to FIG. 1.

When the hook flash is generated from the subscriber phone not shown in step 200, the LP 100 connects a specific dial tone to the subscriber phone that generated the hook flash in step 201, and all existing in the conference call. Connect the hold tone to the slave subscriber.

In operation 202, the subscriber who generated the hook flash is a conference call (also referred to as a conference call (CC)) registered subscriber and a master subscriber. Such a check is made in the SLS 111. That is, when the LP 100 transmits the subscriber number generated the hook flash to the SLS 111, the SLS 111 translates the number through the SNS 112 to check whether the corresponding subscriber is a CC registered subscriber and a master subscriber. It becomes possible.

As a result of such a check, if the subscriber who generated the hook flash is a CC registered subscriber and a master subscriber, the process proceeds to step 203 through step 202, and the LP 100 receives dial information from the corresponding subscriber phone and transmits it to the SLS 111. . When the dial information is received, the SLS 111 proceeds to step 204 and performs a number translation through the SNS 112 to check whether the SLS 111 is the same as the existing slave subscriber number provided with the CC service.

If the check result is not the same, the process proceeds from step 204 to step 205 and the called party calls the number through the SNS 112. When the called party responds, the called party is reconfigured into a conference call by setting up the called party as the slash subscriber as in the conventional CC service method. That is, for example, when there are five slave subscribers in the condition that up to six-way call is possible, if a new incoming subscriber is connected as described above, the subscriber line participating in the conference call service is disconnected in the last order and newly A conference call path is established containing the attempted called party. However, as described above, when there are four or fewer slave subscribers when attempting to connect with a new incoming subscriber, the conference call path is re-formed without disconnecting the subscriber line.

However, if the received dialing information is the same as the slave subscriber number as a result of the check in step 204, the process proceeds to step 206 to cause the LP 100 to cut off the hold tone provided to the corresponding slave subscriber. In step 207, a single call path is formed between the corresponding slave subscriber and the master subscriber to proceed with the call.

If the hook flash is generated in step 208 after performing a single call or reconstructing the conference call made in step 205 described above, the process proceeds to step 209 and the SLS 111 determines whether the subscriber who generated the hook flash is the master. Check

If it is checked, the master proceeds to step 210 and proceeds with the conference call. That is, in the case of the hook flash generated after the reformation of the conference call made in step 205, the conference call proceeds through the newly set call path, and in the case of the hook flash generated in the course of the single call performed in step 207, the single call Terminate and continue the conference call by cutting off the hold tone to the slave subscriber to which the hold tone was provided.

On the other hand, if the subscriber who generated the hook flash as the check result of step 202 is not a CC registered subscriber, a CC registered subscriber and not a master subscriber, or is not a CC registered subscriber and a master subscriber, the process proceeds to step 211. It returns without ignoring the corresponding operation (Don't care). As a result of the check in step 209, if the subscriber who generated the hook flash is not the master, the process proceeds to step 211 described above and operates as described above.

As described above, the present invention provides a conference call service method in which the master subscriber can return to the conference call state after the master subscriber talks alone with one of the slave subscribers during the conference call service provided by the exchange. There is an effect to improve the conference call service provided.
