Meanwhile, the mobile communication network may be directly connected to the multimedia messaging service center. At this time, the mobile communication network is connected to the multimedia messaging center through a relay.

2 is a process flowchart for providing a group service according to the present invention.

A user requests a group service using a mobile communication terminal. The mobile communication terminal has a built-in dedicated program for providing a group service. The dedicated program is driven when the user selects a group service and supports the mobile terminal to update and register the group information. That is, the user drives a dedicated program for group service in the mobile communication terminal. Then, group information may be loaded using the dedicated program. The group information is the same as the information stored in the group database. After the user loads the group information, the user can update the group information. When the group information is updated, the dedicated program sets a flag for the updated group. That is, a flag is set in the group identifier to indicate that there is updated information.

When the user requests the group service using the mobile communication terminal (101), the dedicated program is driven and connected to the group application server using the wireless application protocol (WAP) (102). When the group application server is connected to the mobile communication terminal, the phone number of the mobile communication terminal, that is, the MIN information is checked to confirm the group information of the subscriber corresponding to the MIN information. The group application server checks whether there is a group identifier with a flag set among the group information of the mobile communication terminal. If there is a flagged group identifier, the group application server updates the group information of the subscriber stored in the group database with the group information stored in the mobile communication terminal. Through this process, the group information stored in the mobile communication terminal and the subscriber group information stored in the group database are synchronized (103). In this synchronization process, the subscriber directly accesses the group application server to omit the procedure for updating the group information. That is, the subscriber simply updates the group information in his terminal, and his group information stored in the group database is automatically updated.

When the group information stored in the mobile communication terminal and the group information stored in the group database are synchronized, menus for group service are displayed on the mobile communication terminal. The group service includes a group call capable of simultaneous call among a plurality of subscribers, a voice group transmission service capable of simultaneously transmitting a voice message to a plurality of subscribers, and a text group transmission capable of simultaneously transmitting a text message to a plurality of subscribers. There is a service.

When the user selects a group call from the displayed service menu (104), the group information currently registered is displayed on the display window of the terminal. The group information may include something like "high school friends, family members, torrent school, college motives, company". When the user selects a specific group from the displayed group information (105), the group application server establishes a voice call call with the mobile communication terminal of the calling subscriber who requested the group call using the ARS system (105). In this case, the group application server releases the currently connected data channel and sets up a voice call when the mobile communication terminal is not an SVD terminal that simultaneously provides voice and data. If the mobile communication terminal of the calling subscriber is an SVD terminal, the voice channel may be connected while the data channel is connected. In other words, when the user selects the group information, the group application server knows the selected group information and the user's telephone number. Therefore, the group application server performs the processing procedure for the group call service using the user's telephone number and the selected group information. The group application server sets up a call to the user's telephone number using the ARS system, and the ARS system provides guide voice to the user. For example, the announcement may be as follows: "The selected group is a family. You are currently connected to the phone. Please wait." The ARS system then reports to the user the results of the call connection to the group members, and then combines the calls of the connected group members to provide a group call. The technique for providing the group call is a known technique, and further detailed description thereof will be omitted.

On the other hand, when the voice group transmission is selected from the displayed group service list (104), the group application server provides the group information registered as the mobile communication terminal. The provided group information is displayed on the display window of the mobile communication terminal. If the user selects a specific group from the displayed group information (107), the voice mailbox function is driven to record the voice message. In this case, the group application server releases the currently connected data channel and connects to the voice mailbox when the calling subscriber terminal is not the SVD terminal, and connects to the voice mailbox while connecting the data channel in case of the SVD terminal. You can also connect directly.

When a voice call is connected between the voice mailbox and the calling subscriber terminal, a voice message to be transmitted is recorded according to a conventional procedure (108). When recording is complete, all of the group members selected by the user are notified that there is a received voice message (109). The technique of recording and transmitting the voice message is achieved by using a conventional technique, and a detailed description thereof is omitted.

On the other hand, when the character group transmission is selected from the displayed group service list (104), the group application server provides the group information registered as the mobile communication terminal to be displayed on the display window of the mobile communication terminal. When the user selects a specific group among the displayed group information (110), a text to be transmitted for text message transmission is received. After the input of the text to be transmitted is completed, if transmission is selected, the text is stored (111), and the text message is sent to the selected group members (112). Meanwhile, another method of text transmission may include a method of receiving a character to be transmitted first and then selecting and sending a group. The technology of receiving the text and simultaneously transmitting the same to a plurality of subscribers belonging to the group may be achieved by using a conventional technology, and a detailed description thereof will be omitted.

According to the present invention as described above, by installing a dedicated program for the group service in the mobile communication terminal, by using the program to update the group information, the group information is automatically updated when the group application server and the mobile communication terminal is connected By doing so, the user can easily update the group information, and the group call, the voice group transmission, and the text group transmission service can be provided using the group information.
