 'Jewook Choi' and 'Nadaeyeol' are the same high school alumni group, but 'Kee Eun-gwang' is not a high school alumni, select the high school alumni item on the group menu of FIG. 5A and the direct input menu of FIG. 5B or the telephone of FIG. 5C The conference can be connected by selecting 'Kee Eun Kwang' from the directory menu.

As such, the additional input 442 may be manipulated in the phone book in FIG. 4D, and the group, phonebook, and direct input, which are submenus of the multi-call menu, may be repeatedly selected in FIGS. 5A to 5C. This gives you the flexibility to choose the participants in the conference.

FIG. 6 is a flowchart of a method for calling and receiving a conference call according to an embodiment of the present invention, and FIG. 7 is an example of a screen asking whether a conference call partner approves a conference call connection. Hereinafter, a description will be given with reference to FIGS. 6 and 7.

Referring to FIG. 6, a multi-party call caller selects a phone number of a counterpart belonging to a group to be conferenced in a multi-call menu 412 which is a submenu of the phone book 300 or the main menu (S610). Command (S620). In this case, the controller 230 controls the message input window to be automatically generated on the display unit 240 to input a matter related to the conference.

The controller 230 generates a telephone number list and a group name of the conference participants when the caller commands the conference call, and causes the mobile communication module 210 of the mobile communication terminal 110 to transfer the telephone number list and the group name to the call server. To transmit to 130 (S630). At this time, a multi-party call is connected between the mobile communication terminal and the call server 130 (S640).

The call server 130 receives the telephone number list of the multi-party counterparts from the mobile communication module 210 and requests a multi-party call call to the terminals of the multi-party counterparts included in the received telephone number list (S650).

At this time, the call server 130 transmits the telephone numbers and group names of the conference participants including the caller to the mobile communication terminals 110 of the conference counterparts, respectively. In addition, the call server 130 determines whether there is an approval for the call request from the mobile communication terminal 110 of the multiparty call counterpart (S660).

In the terminal display window of the multiparty call counterpart, names, phone numbers, and group names of the multiparty call participants are displayed, and a popup window is generated asking whether to approve the multiparty call request.

Referring to FIG. 7, the upper portion 710 of the display window displays a group name of a group of participants of a multi-party call, and a group name of a multi-party call participant including a caller is displayed below the group name 720. do.

The pop-up window 730 displays the contents of the message written by the sender 'Kee Eun Kwang', for example, "I'm in Gangnam SPACE 9". In addition, the pop-up window (730) prompts you to approve the conference call, "Do you want to accept the conference call from 'Kee Eun-Kwang'?" Along with a selection window, for example, " connection 740 ", " deny 750 ", " standby 760 "

When the multi-party call receiver selects "deny 750" or does not answer, the multi-party call is formed between the mobile communication terminal 110 and the call server 130 (S670).

When the conference call recipient selects "connect 740" and the approval of the conference call request is made, the conference call set up between the mobile communication terminal 110 and the call server 130 is connected to the terminal of the called party who has a response. (S680).

When the conference call receiver selects "standby 760", the connection of the conference call formed between the mobile communication terminal 110 and the call server 130 is suspended (S690).

2. After the conference call

8A to 8D illustrate screen examples of whether or not a multi-party call is connected to a multi-party call on a terminal of each caller.

표시 Status of participants in the conference

When the conference call is connected, each terminal of other conference participants except themselves may display the call status of the conference participants transmitted from the call server 130.

That is, when the conference call is connected, the conference call participant is displayed on the display unit 240 of the terminal 110 of the participant connected to the conference call in a predetermined display manner so that the name of the user who made the first call can be distinguished from the conference call participants. . In addition, the participant status may be displayed by using a predetermined display method, for example, an icon or a color.

For example, referring to FIG. 8A, 'call 811' is displayed next to the name of the multi-party caller, 'Kee Eun-gwang', and 'connect 814' is displayed next to the 'Sang-Sil' name connected to accept the conference. Can be displayed. If you attempted a conference call but did not connect, you would see "Connecting (812)", and if there was no answer or declined for the conference call request, you will see "No Answer (815)" or "Reject (813)". May be displayed.

Based on this information and call status, the conference participant simply marks the check box 830 in front of the phone list to participate in the conference or select a specific party to select group SMS, group MMS, Voice modulation, sound correction, etc. can be facilitated. In FIG. 8A, the checkbox 820 next to the high school group name is for the entire selection.

For example, when the sound correction 860 of the sound pack 850 is selected in FIG. 8A, check boxes of 'Kee Eun-gwang' and 'Hwang Sae-il' connected to the conference call and select '3. It is possible to adjust the height of the sound for each participant in the conference by selecting the sound correction 860 item which is a submenu of '850'. In addition, by selecting a check box 820 next to the group name of the high school pupils, the entire selection can be made.

추가 Add conference participant

Immediately after the conference is connected, if a new recipient enters the call during the conference, or if the conference participant is exited, the call server 130 or the corresponding terminal may request that the conference participant know the current conference status. Guide text can be sent on the terminal.

For example, referring to FIG. 8B, when 'Chief Choi' is lately connected to the conference during a conference call, a message indicating that 'Chief Choi participated in the call (870)' is transmitted to the terminal of the existing conference participants. Can be.

However, during the call, each caller does not make a call while looking at his terminal, and during a multi-party call, it is difficult to clearly recognize the participants' positions and exits, so not only guide text but also voice guidance through other speakers of the conference participant's speaker (not shown) You can notify your entry and exit during the call.

Existing call participants, ie the conference call caller as well as the conference call recipient, may select the Invite 840 menu, which is a submenu of the menu item on the terminal screen, to add a new call participant. If you select the Invite (840) menu, the call participant may return to the phone book 300 or the main menu 410 as described with reference to FIGS. 3 and 4 to select a call participant. If a new call participant is connected to the conference call, voice announcements as well as guide text can be used to announce entry during the call.

In some cases, even when a general two-person call is not a multi-party call, the user of the existing terminal may select the Invite (860) menu which is a submenu of a menu item on the display unit 240 of the terminal 110 as described above. When a third party is requested to the third party, the already established call is switched to the conference.

3. Redial for a conference

Referring to FIG. 8A, a status of whether a conference is connected to a conference is displayed on a terminal of each caller. If there is no response to the multi-call call request or explicitly rejects, a letter or icon indicating 'no answer 815' or 'deny 813' may be displayed on the terminal of each multi-party call target.

If there is a member of the group to whom the conference is not connected, the conference caller as well as other recipients may attempt to recall by pressing the Invite 860 button.

For example, in FIG. 8A, the conference participant may automatically search for the terminal of the mobile terminal that is not connected and repeatedly request the conference call.

Whether the conference participant who is not connected is automatically connected or the conference participant is manually connected may be set in the configuration 431 of the conference menu of FIG. 4B. In particular, in case of automatic connection, call cycle and repetition frequency can be set.

In addition, the multi-party call recipient 'Han Sae-il' may also attempt a multi-party call request by pressing the direct move key and the invite button on the menu (840).

The same is true for a conference call interrupted during a call after the call connects.

For a conference call request, the conference recipient can enter the reason for the rejection of the conference to proactively block subsequent redial requests if the conference is explicitly rejected.

For example, in FIG. 7, the terminal of other conference participants other than Lee Dong-seok except for Lee Dong-seok, when the user explicitly entered the conference (750) and entered 'Conference' as the reason for rejection in the rejection input window (770). The letter 'in conference' is displayed next to the name 'Seong Dong-seok'.

Participants whose service packs are supported on their mobile terminals among the conference participants can use sound packs, text packs, and visual packs during the conference.

Referring to FIG. 3 or 4b, after selecting a target to send a group SMS, the group SMS can be sent using the 'SMS call 340' of FIG. 3 or the 'SMS call 427' menu of FIG. 4B. . In this case, the display unit 240 of the terminal of the recipient of the group SMS may display the names and phone numbers of other recipients as well as the sender of the group SMS. Thus, the recipient can reply to the SMS by selecting all or at least one person from among the other recipients, including the sender.

In addition, in another embodiment, the name of the conference participant together with the conference-related message (for example, a conference topic, etc.) written by the conference caller to the other party who does not respond to the conference call request because the conference is not connected. And phone numbers and group names are sent in the form of group SMS.

Referring to FIG. 8A, when the conference is connected, the connection status of the conference participant is displayed on each terminal screen of the conference participant. Therefore, the conference call receiver selects the group SMS by using the direction key and the selection key as well as at least one of the participants who are connected to the conference but not the participants who are rejected or waiting, or who are not connected to the conference without reply. Can transmit

The same may be applied to the case of sending a group MMS.

2. Comments MMS

9 is a flowchart illustrating a method for repeatedly sending a feedback by repeatedly replying to a multimedia message (MMS) in a mobile communication terminal according to an embodiment of the present invention.

First, the mobile communication terminal 110 of the multi-party caller transmits content such as a digital photo to the mobile communication terminal 110 of at least one or more participants among the multi-party participants.

In this case, the content may be transmitted using a multimedia messaging service (MMS). Multimedia messaging service is a service that can send and receive color pictures, characters, video, etc. between mobile communication terminals as in the wired Internet, and unlike the short message service that only sends and receives sentences, it is a service that can transmit and receive various multimedia contents.

In the mobile communication terminal receiving the content, the content transmitted from the mobile communication terminal of the multiparty caller is reproduced. The user can leave a comment after viewing the content. Such a comment is again transmitted to the mobile communication terminal of the multiparty call sender through the short message service (S920).

The mobile communication terminal of the multi-party caller attaches a comment received from another mobile communication terminal that has received the content to the corresponding content (S930), and reconstructs the content to which the comment is added.

Another mobile communication terminal 110 that has received the reconstructed content from the caller's mobile communication terminal may add a comment again to the content to which the comment is attached. Comments attached from the other mobile communication terminal 110 are retransmitted to at least one or more mobile communication terminals of the conference participants through a short service (S940).

The retransmitted mobile communication terminal may attach a comment received from another mobile communication terminal to the content again. Such a process may be repeatedly performed by the same process with respect to a comment transmitted from another mobile communication terminal 110.

<Sound Pack>

The effect sound, the background sound, the voice modulation data, or the vibration pattern data are downloaded from the call server 130 through the communication network 120 using the download unit 280 of the mobile communication terminal 110. The downloaded effect sound, background sound, voice modulation data, or vibration pattern data is stored in the storage unit 250 of the mobile communication terminal.

In particular, in the case of the effect sound and the background sound, the user of the mobile communication terminal may record a voice or a sound through a microphone (not shown) of the terminal, and store and set it in the storage unit 250. Therefore, during the sound effect, the caller can record the voice of the caller and then hear the conference call.

Subsequently, when the conference call is initiated, the conference call participant may first select at least one or more participants from the conference call participant, and select a desired sound effect, background sound, voice modulation, or vibration pattern for each participant by operating a separate button.

Finally, the selected sound effect, background sound, voice modulation or vibration pattern is output to the communication terminals of the selected conference participants.

10A to 10D are menu configurations in which voice modulation, effect sounds (sound cones), background sounds, and vibration (vicon) types are set according to an embodiment of the present invention.

The conference call participant may select at least one of voice modulation, an effect sound (sound cone), a background sound, and a vibecon by selecting another conference call participant connected to the conference in FIG. 8A and clicking the sound pack 850 in the menu.

For example, in the case of voice modulation, not only the conference call sender but also the conference call receiver may selectively perform voice modulation. For example, referring to FIGS. 8A and 10A, after checking 'Kee Eun-gwang' as a multi-party caller in FIG. 8A and selecting 'Bee' in FIG. 10A, the voice of the multi-party caller may be referred to as 'bee'. Can be modulated The same is true for the conference recipient. In FIG. 8A, not only the multi-party call originator but also one or more multi-party call receivers may simultaneously perform voice modulation.

Also in the case of the effect sound (sound cone), the background sound, and the vibration (vicon), the menu screens of FIGS. 10B to 10D can be used in the same manner as in the case of the voice modulation.

<Visual Pack>

If a capture operation key signal is input through a separate key or a menu button for capturing during use of the mobile communication terminal 110, the controller 230 captures screen information currently displayed on the LCD screen and stores the information on the storage 250. Save it.

Explain, for example, a case where an appointment is made to meet at a specific location for a high school reunion.

When a multi-party call participant using the mobile communication terminal 110 having a GPS function searches for directions of an appointment place of a high school reunion meeting using GPS, the multi-call participant may capture and transmit the directions to other multi-party call participants.

Referring to FIG. 8A, during a conference call, after capturing directions of a high school reunion meeting location using a 'screen capture' menu, which is a submenu of the visual pack 870 on the menu, or a specific key for capturing, the conference call participant You can select some or all of them to send the captured directions using group MMS.
