2. After a multipart call connection

FIGS. 8A to 8D show examples of the statuses of the parties of the conference being displayed on the terminals of the respective parties.

⑴ Marking of the participants of the conference call

When the multi-party call is connected, the call status of the multi-party participants transmitted from the call server 130 may be displayed on each terminal of the multi-party participants other than the multi-party call participant.

That is, when the conference call is connected, the display unit 240 of the participants 110 connected with the conference call displays the presence or absence of the conference call of the participants of the conference and the name of the user of the first caller . In addition, the participant status may be displayed by a predetermined display method, for example, an icon may be displayed or a color may be different.

For example, referring to FIG. 8A, 'calling (811)' is displayed next to 'Gyeolgwang', which is a multi-party caller, and 'connection 814' is entered next to ' Can be displayed. 815 "or" Deny 813 "is displayed in the case of" Choi Jae Wook "when the user attempts to make a multi-party call but is not connected. . ≪ / RTI >

A participant of the conference can select a specific party by joining a conference by selecting a check box 830 in front of the telephone list based on the information and the call status during a conference call, Voice modulation, sound correction, and the like can be facilitated. The check box 820 next to the high school alumnus group name in FIG. 8A is for the entire selection.

For example, if the sound correction 860 of the sound pack 850 is selected in FIG. 8A, a check mark is displayed in the 'yellow light', 'amber light', and '3. sound pack 850) ', which is a submenu of' Voice Control '(860). You can also make a full selection by making a check mark in the check box 820 next to the group high school alumni.

⑵ Add a conference call participant

If a new recipient enters the call immediately after the conference call, or when the conference call participant is exited, the call server 130 or the corresponding terminal notifies the conference participant of the current conference call The guide letter can be sent on the terminal.

For example, referring to FIG. 8B, when 'Choi Je-wook' is connected to a multi-party call during a multi-party call, '' Choi Je- wook participated in the call (870) '' is transmitted to the terminals of the existing multi- .

However, since the callers do not make a call while viewing their terminal during the call, it is difficult to clearly recognize the entry and departure of the participants during the conference call. Therefore, not only the guide letter but also the voice information through the speakers (not shown) The user can be informed of the entry and exit during the call.

Conventional call participants, i.e., multi-call originators as well as multi-party call recipients can select the menu 840 on invitation (840), which is a submenu of menu items on the terminal screen, on Figure 8a, to add a new call participant. If the user selects the invite (840) menu, the user can return to the phone book 300 or the main menu 410 to select a call participant, as described with reference to FIG. 3 and FIG. When a new call participant is connected to a multi-party call, as described above, it is possible to notify the user of the call during the call by voice guidance as well as a guide letter.

In some cases, the conventional terminal user may select the invite (860) menu, which is a submenu of the menu item on the display unit 240 of the terminal 110, as in the case of the conventional two- When a multiparty call is requested to a third party, the already set currency call is converted into a multi-currency call and set.

3. Redial for multiparty calls

Referring to FIG. 8A, the status of the multi-party call connection status of the parties to be multi-party is displayed on the terminals of the respective parties. If there is no response to the request for the multi-party call or if it is explicitly denied, a character or icon indicating 'no answer (815)' or 'rejection (813)' may be displayed on the terminal of each multi-party.

If there is a member of the group to which the conference call is not connected, not only the conference call originator but also other recipients may attempt to call again by pressing the invite button (860).

For example, in FIG. 8A, a participant of a conference call can automatically request a terminal of a non-connected 'mobile station' to repeatedly request a conference call.

It is possible to set whether the automatic connection of the unconnected conference participants or the manual connection of the conference participants in the configuration setting 431 of the conference menu shown in FIG. 4B. Especially, in the case of automatic connection, it is possible to set the call interval and the number of repetitions.

Also, 'Hwang Seil', which is a multiperson call recipient, can also make a request for a multi-party call by directly pressing a move key and an invite button (840) on the menu.

This is also the case for multiparty participants who were interrupted during a call.

When a multilateral call recipient explicitly denies a multilateral call, the recipient can enter a reason for denial of the multilateral call in advance to prevent the subsequent request for re - calling.

For example, in FIG. 7, when the 'mobile station' explicitly rejects the confidentiality of the confidentiality of the confidential information (750) and inputs 'during a conference' as a reason for rejection in the rejection reason input window 770, , The letter 'during a meeting' is displayed next to the name of the mobile station.

Participants who support service packs in their mobile communication terminals among the conference participants can use sound packs, character packs, and visual packs during the conference call.

<Character pack>

1. Group SMS or Group MMS

Referring to FIG. 3 or 4B, after selecting a person to whom the group SMS is to be sent, the group SMS can be originated by using the 'SMS sending (340)' of FIG. 3 or the 'SMS sending (427) . In this case, the name and telephone number of not only the caller who sent the group SMS but also other recipients may be displayed on the display unit 240 of the recipient's terminal receiving the group SMS. Thus, the recipient may select all or at least one of the other recipients, including the sender, to reply the SMS.

Further, in another embodiment, when a call is not answered in response to a request for a multi-party call, a message (for example, a multi-party call subject) created by the call originator of the multi- Phone number, and group name are sent in group SMS format.

Referring to FIG. 8A, when the conference call is connected, the connection status of the conference participants is displayed on each terminal screen of the conference call participant. Accordingly, the multi-party call recipient can select at least one of the participants who have not been connected with the conference call without returning the rejected or standby message, as well as the participant who is connected with the conference call using the direction key and the selection key, Lt; / RTI &gt;

The above description can be applied equally to a case where a group MMS is transmitted.

2. Comment MMS

9 is a flowchart illustrating a method of 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-call originator transmits content such as digital photographs to the mobile communication terminal 110 of at least one participant of the conference call at step S910.

At this time, the transmission of the content can be performed using a multimedia messaging service (MMS). Multimedia messaging service is a service that can exchange color pictures, characters, videos, etc. between mobile communication terminals as in the wired Internet, and is a service capable of transmitting and receiving various multimedia contents unlike a short message service which exchanges sentences only.

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

The mobile communication terminal of the multi-party caller attaches a comment received from another mobile communication terminal receiving the content to the corresponding content (S930), and the comment is reconstructed as the added content.

The other mobile communication terminal 110 having received the reconfigured content from the sender's mobile communication terminal can add a comment to the commented content again. The comment attached to the other mobile communication terminal 110 is retransmitted to at least one of the mobile communication terminals through the short message service at step S940.

The re-transmitted mobile communication terminal can attach a comment received from another mobile communication terminal to the content again. Such a process can be repeatedly performed on the comment transmitted from another mobile communication terminal 110 by the same process.

<Sound Pack>

[ And stores the downloaded sound effect, background sound, voice modulation data, or vibration pattern data in the storage unit 250 of the mobile communication terminal.

In particular, in the case of effect sound and background sound, a user of the mobile communication terminal may record voice or sound through a microphone (not shown) of the terminal and store and record the voice or sound in the storage unit 250. Therefore, among the effect sounds, the caller's own voice can be recorded and then heard during the multi-party call.

Then, when the conference call is started, the participant of the conference call first selects at least one participant of the conference participants, and operates a separate button to select a desired effect sound, background sound, voice modulation, or vibration pattern for each participant selected.

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

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

The conference participant can select at least one of voice modulation, effect sound (sound deicon), background sound, and vibrate by clicking on the sound pack 850 in the menu after selecting another conference call participant to which the conference call is connected in FIG. 8A.

For example, in the case of voice modulation, not only a multi-call originator but also a multiparty call recipient can selectively voice-modulate. For example, referring to FIG. 8A and FIG. 10A, if 'Vice' is selected in FIG. 10A after checking 'Gyeolgwang' as a caller of a multiparty call in FIG. 8A, the voice of the caller of the multi- Modulation is possible. The same applies to multiperson call recipients. In FIG. 8A, it is possible to voice-modulate not only a multi-call originator but also one or more multi-party call recipients at the same time.

In the case of an effect sound (sound decon), a background sound, and a vibration (vibe con), a menu screen of Figs. 10B to 10D can be used in the same way as in the case of voice modulation.

<Visual Pack>

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

For example, a high school reunion meeting is held in a specific place.

When a conference participant using the mobile communication terminal 110 having the GPS function searches the map of the appointed place of the high school alumni association using the GPS, the map can be captured and transmitted to other conference participants.

8A, during a conference call, a map of a promised place of a high school alumni association is captured using a 'screen capture' menu or a specific key for capturing, which is a sub menu of the visual pack 870 on the menu, The user can select a part or all of them and transmit the captured map using the group MMS.

Referring to FIGS. 3 and 4B, a route is captured using a specific key for capturing, not during a multi-party call, and the captured route is captured using the MMS originating 350 of FIG. 3 or the MMS originating 428 menu of FIG. 4B Lt; / RTI &gt;

As another embodiment of the visual pack, it is possible to provide a service in the form of a theme photo album that provides basic themes such as entrance and graduation albums. For example, in the case of a multi-talk group of a high school alumnus, a photograph may be uploaded to a theme photo album stored in the mobile communication terminal 110 or the call server 130 so that only a high school alumni who has been granted the sharing permission can access the photo.
