Description

How to service a conference call {METHOD FOR PROVIDE MULTIPLEX CALL SERVICE}

TECHNICAL FIELD The present invention relates to telecommunications services, and in particular, to a method for multilateral calling services.

Currently, a mobile phone has been commercialized to allow a wireless call.

In addition to the 1: 1 call function, the wireless call service also provides conference call service for simultaneous multi-party calls.

In the conference call method, when a user wants to talk with another person at the same time, he / she calls the other party by pressing the corresponding phone number to enable simultaneous conferences.

In other words, while simultaneously maintaining the call for the multi-party simultaneous call to the desired counterpart to attempt the simultaneous call.

There is currently a TRS (Trunked Radio System) which is intended only for multi-party simultaneous calls. This method does not dedicate a constant frequency but binds each independent channel into one so that a large number of users share it, and thus requires a dedicated base station and a dedicated terminal.

However, in the related art, when it is necessary to make a simultaneous call with a plurality of people in a meeting or the like, it is inconvenient to attempt to make a call by inputting each desired counterpart phone number in turn while maintaining a call with an arbitrary counterpart.

That is, in the related art, when it is necessary to make a call with several people at the same time, it is inconvenient to attempt a call after individually searching or inputting each counterpart phone number to be called.

Therefore, the present invention is to make it easy to talk with a large number of people to make a phone call at the same time after entering all of the phone numbers to be called when a number of people should be talking at the same time to improve the conventional inconvenience The purpose of the present invention is to provide a method for multi-party call service.

1 is an exemplary view showing a screen showing a conference call in an embodiment of the present invention.

2 is an operational flow diagram for a multi-party call process in an embodiment of the present invention.

The present invention comprises the steps of setting up a multi-call service in order to achieve the above object, inputting a plurality of counterpart phone numbers to be called, attempting to make a call connection simultaneously with the plurality of input phone numbers; And performing a multi-party call while displaying a call connection state according to the incoming call.

In the above, the plurality of phone number inputs may be input by searching a phone book or directly by key selection.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the embodiment of the present invention, it will be described on the assumption that the multi-call is conducted to the mobile phone and the multi-party call uses the TRS method.

FIG. 2 is a flowchart illustrating a multi-party call process according to an embodiment of the present invention. As shown in FIG. 2, a first step of displaying a plurality of phone number input screens for a multi-party call, and a multi-party call using a phone book or a keypad. A second step of inputting a desired phone number; and a third step of simultaneously calling the plurality of input phone numbers when the call button is pressed; and the incoming call response while keeping the call waiting state for the other party who does not answer the call. And performing a fourth step of checking whether there is a call and the fifth step of proceeding with the simultaneous call between the parties having an incoming response to the call.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

When the user wants to conduct a multi-party call, the user selects the telephone function menu on the menu screen of the mobile phone.

In this case, a screen for selecting a telephone function is displayed on the mobile phone screen as shown in FIG. Here, it is assumed that the multi-call service is set by selecting the 'multi-call number' item.

Subsequently, when a screen for inputting a multi-call number as shown in FIG. 1 (b) is displayed, the user inputs a phone number of a counterpart who wants to make a call, using the menu button as shown in FIG. 1 (c). The phonebook is searched and the corresponding phone number is entered. In this case, the number stored in the phone book can be searched or a number that has been recently called can be searched to conveniently enter a multi-phone number. At this time, an example of the input multi-phone number is shown in FIG.

Subsequently, when the input of the phone number of the counterpart who wishes to make a multi-call is completed, the user presses a call button and simultaneously attempts to connect the call to the plurality of inputted phone numbers.

Thereafter, a response to the incoming call is received from the called party's telephone.

At this time, depending on whether the call is connected to the mobile phone screen as shown in Fig. 1 (f) [call] indicating that the call is in progress, [waiting] indicating the call waiting state, [reject] indicating the state that the other party rejected the call and The call connection status with each called party is displayed.

Accordingly, the multiparty call including the user is made.

If the other party in the standby state allows the call, the [wait] state is displayed as the [call] state for the corresponding party as shown in FIG. 1 (g). The other party can immediately join the ongoing conference.

That is, when a call is connected to another person who is in a call waiting while talking with some person who attempted the call, the user can join the ongoing call without additional work. At this time, when the call status is changed, for example, when the call is transferred from the call waiting state to the call connection state or when the call state is changed from the call state to the call reject state, a sound effect is generated so that the user can easily recognize the call state with each caller. Make sure

As described in detail above, the present invention has an effect of providing convenience to a user by inputting a plurality of counterpart phone numbers desired for a multi-party call and simultaneously attempting a call and displaying a call state with each counterpart.

In addition, the present invention has the effect that the phone number input time can be shortened by inputting a plurality of counterpart phone numbers desired for the multi-party call before the call connection using the phone book or the like.
