If the user selects 'retransmission' after selecting a message to be retransmitted from the transmitted message list stored in the submenu 'sent message', the controller 180 of the calling terminal 100A may select the message Provides an environment for editing messages. At this time, the controller 180 of the calling terminal 100A may read and display the previous recipient list based on the header information of the transmitted message.

In the message editing environment, the calling terminal 100A adds the missing receiving terminal 2 (100C) to the called party list (S107) according to user input as shown in FIG. 6C. At this time, the controller 180 of the originating terminal 100A updates the header of the message to be retransmitted according to the modification. In other words, since the header of the message to be retransmitted is updated by modification of the receiver list, update information on the modified receiver list information, retransmission status, whether to update the header or the like can be inserted into the header of the message to be retransmitted.

Then, the originating terminal 100A retransmits the updated header message (S109). The server 400 having received the retransmitted message transmits the retransmitted message to the receiving terminals 100B and 100C based on the header information of the retransmitted message. The server 400 transmits only the update information to the receiving terminal 1 (100B) which receives the re-transmitted message repeatedly (S111). The receiving terminal 1 (100B) updates the header of the previously received message according to the update information (S113). Accordingly, the receiving terminal 1 (100B) does not display the same message in duplicate, but outputs an indicator indicating that the header has been updated in the received message.

In addition, the server 400 transmits the retransmitted message to the receiving terminal 2 (100C) added to the receiver list (S115). In other words, the receiving terminal 2 (100C) receives the retransmitted message as a new message. The received message is stored in the memory 160.

As described above, the calling terminal 100A generates a message to be transmitted according to the operation of the user input unit 130, and transmits the message to the inputted receiving terminal (S201 to S205).

Thereafter, when retransmission of the message is requested due to a change in the transmitted message content, the originating terminal 100A modifies the content of the message according to a user input (S207). In other words, the calling terminal 100A moves to the 'outbox' menu as shown in FIG. 6A according to the input data from the user input unit 130, moves to the 'outgoing message' submenu, and selects a message to be retransmitted. If the user selects 'retransmission' after selecting a message to be retransmitted from the transmitted message list stored in the submenu 'sent message', the controller 180 of the calling terminal 100A may select the message Provides an environment for editing messages.

Then, in the message editing state, the calling terminal 100A modifies the contents of the message from '4th floor small conference room' to '6th floor conference room' according to input data from the user input unit 130 as shown in FIG. 8A.

When the modification of the message content is completed, the originating terminal 100A retransmits the updated message (S209). At this time, the control unit 180 of the calling terminal 100A inserts information related to the update of the message content into the header of the modified message.

The server 400 having received the retransmitted message transmits the retransmitted message to the receiving terminals 100B and 100C based on the header information of the retransmitted message. The server 400 transmits only the update information to the receiving terminal 1 (100B) that receives the re-transmitted message repeatedly (S211). The receiving terminal 1 (100B) updates the contents of the previously received message according to the update information (S213). At this time, the receiving terminal 1 (100B) controls the underline, the font color, and the background color of the updated part so that the recipient can easily check the contents of the updated message, as shown in FIG. 8B. Then, the receiving terminal 1 (100B) may not display the re-transmitted message in the received message list, but may switch the message to an unread message so as to output or identify an indicator that the corresponding message is updated.

In addition, the server 400 transmits the retransmitted message to the receiving terminal 2 (100C) added to the receiver list (S215). In other words, the receiving terminal 2 (100C) stores the retransmitted message as a new message.

9 is a flowchart illustrating a mail / message retransmission method of a mobile terminal according to another embodiment of the present invention. The present embodiment will be described by taking as an example a case where a message is retransmitted after adding a recipient and modifying the contents of a message.

As described above, the calling terminal 100A generates a message to be transmitted according to an operation of the user input unit 130, and transmits the message to the inputted receiving terminal (S301 to S305).

When the sender adds the missing recipient in the previous message transmission and corrects the transmitted message contents, the originating terminal 100A corrects the contents of the message according to the user's input, and sends a desired recipient to the recipient list (S307). First, the calling terminal 100A moves to the 'outbox' menu as shown in FIG. 6A according to the input data from the user input unit 130, moves to the 'outgoing message' submenu, and selects a message to be retransmitted. 6B, when the 'retransmission' button is selected after selecting a message to be retransmitted from the transmitted message list stored in the submenu 'sent message', the controller 180 of the calling terminal 100A transmits Provides a state in which the selected message can be edited.

Then, the originating terminal 100A adds the removed recipient as shown in FIG. 6C according to the input data generated from the user input unit 130, and transmits the message content to the 'fourth floor small conference room' To 'Sixth Floor Conference Room'.

When the editing of the message is completed, the calling terminal 100A retransmits the updated message of the recipient list and the message content (S309). At this time, the controller 180 of the originating terminal 100A inserts the update information related to the update of the recipient list and the message contents into the header of the modified message. In this embodiment, the update information is inserted into the header of the transmitted message. However, the update information may be separately transmitted.

The server 400 having received the retransmitted message transmits the retransmitted message to the receiving terminals 100B and 100C according to the header and the update information of the retransmitted message. The server 400 transmits only the update information to the receiving terminal 1 (100B) in which the retransmitted message is duplicated (S311). The receiving terminal 1 (100B) updates the header and contents of the previously received message according to the update information (S313). At this time, the receiving terminal 1 (100B) controls the underline, the font color, the background color, and the like in the updated part so that the recipient can easily check the contents of the updated message, as shown in FIG. 8B.
