A method and apparatus simultaneously displays the main text and/or more attached filed of a message received in a mobile terminal. This simultaneous display allows a user to confirm the main text and attached files in the message. The main text and attached files may be shown in respective areas of the display.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to wireless communications, and more particularly to systems and methods for displaying messages on a mobile terminal.

2. Background of the Related Art

A message system is a communication scheme for transmitting and receiving various kinds of data such as letters, etc. between users through one or more communication networks. Users knowing message addresses, for example, can transmit and receive messages with other parties through a wired or wireless Internet. The messages may include main text and one or more attached files to be transmitted to the other party. The attached files may include text files, image files, moving picture files, sound files, etc. which are independent of the main text.

Messages including one or more attached files are described above can be confirmed with mobile terminals connected to communication networks. Mobile terminals such as portable mobile phones and personal digital assistants (PDAs), have been more widely used for confirming messages in recent times.

FIG. 1shows how part of the main text of a message including an attached file may be displayed. In this figure, only file names of the attached files are displayed. As shown inFIG. 1, when the message is confirmed using a mobile phone having a display unit which is much smaller than display units of stand-type personal or notebook-type personal computers, only the file names of the attached files are displayed. Their names can be selected one-by-one to confirm details thereof. This method of display and confirmation is troublesome because it requires multiple key manipulations.

Also, when an attached file directly related to details of the main text is displayed, it is impossible to simultaneously confirm the main text and the attached file, so there is a disadvantage in that all the details of the message and file cannot be understood.

Japanese Patent Application Laid-open No. 2000-285047 discloses a technique of automatically reproducing an attached file included in a message, but this technique has a problem in that since the main text cannot be simultaneously confirmed even if the attached file is reproduced, the main text and the attached file cannot be simultaneously confirmed.

SUMMARY OF THE INVENTION

Another object of the present invention is to provide a method of and an apparatus for displaying a message on mobile terminal, which when a message sent to an account (message address) of a user is intended to be confirmed, allows a user to more conveniently confirm the message by simultaneously displaying main text of the message and an attached file included with the message preferably in respective specified areas of a display unit.

In order to accomplish the foregoing objects, according to an aspect of the present invention, there is provided a method of displaying a message on mobile phone, comprising a main text of the message; at least one attached file of the message; a displaying unit simultaneously both the main text and the attached file.

The method further comprising a converting process of message into a synchronized multimedia integration language (SMIL) file that is set to execute the attached file and display it at the display unit simultaneously with the main text; and a displaying process of message in such way by driving the SMIL file in response to press of the key indicating the confirmation of the message.

In the converting process the SMIL file is set to allot display area for the attached file and main text to display the attached file and the main text simultaneously using display-specifying data stored in a memory.

The method further comprises a setting process of user by inputting the display-specifying data to be stored in a memory. The display-specifying data may contain inputting data indicating whether a sound file would be executed or not, and/or inputting data indicating when the sound file to be executed. In the converting process if a number of attached file exceeds that of displaying area to display the attached file allotted by display-specifying data, the attached file is set to be displayed sequentially and rotationally.

The attached file may be set to be displayed sequentially and rotationally in response to press of a predetermined key. Alternatively, the attached file may be set to be displayed sequentially and rotationally with a predetermined cycle. The predetermined cycle with which the attached file is set to be displayed sequentially and rotationally is set using the display-specifying data.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 2is a block diagram illustrating a structure of a mobile terminal to which the present invention may be applied,FIG. 3is a diagram illustrating a screen of the mobile phone to which the present invention is applied when confirming a message, andFIG. 4is a flowchart illustrating a procedure of displaying a message in the mobile phone according to the present invention.

Referring toFIG. 2, the mobile terminal basically comprises a key input unit10. A control unit20, a radio frequency (RF) transmitting and receiving unit30, a display unit40, a memory50, a sound processing unit60, and an e-mail display setting module70. The key input unit includes a plurality of numeral keys and functional keys, which output key data corresponding to the key pressed by a user. The control unit performs general operation controls of the mobile phone. The radio frequency (RF) transmitting and receiving unit carries out amplification, filtering, modulation, and demodulation of RF signals transmitted and received through an antenna. The memory stores data received through the RF transmitting and receiving unit30and key data input through the key input unit10, and specifically stores display-area specifying data of a message input by a user. The sound processing unit carries out modulation and demodulation of sound signals input and output through a microphone and a speaker under control of control unit20.

The mobile phone transmits and receives a message through a wireless communications network such as the Internet. That is, when a user establishes an account (message address) in the mobile terminal, the user confirms messages by inputting an identifier and a password of the account.

When a message arrives at the account established in the mobile terminal and a key for confirming the message is pressed, the control unit20outputs a control signal for displaying the received message in the display unit40. The message display setting module70then converts the format of the message before displaying the message in the display unit after the message is receivecd.

The message display setting module70sets (converts) display formats of the main text and the attached file based on a language such as but not limited to a synchronized multimedia integration language (SMIL). SMIL is an integrated language which can temporally and spatially reproduce various multimedia data such as text, image, audio, video, etc.

When a message is received, the message display setting module70specifies the display areas for the main text and attached files, or sets a reproduction time for an audio file when the audio file is attached, and then converts the message to an SMIL file. The control unit then displays the received message in the display by driving the SMIL files in response to activation of a key indicating confirmation of the message by the user.

A message can include main text and at least one attached file. Confirmation of a message includes a main text and a plurality of attached files which will be now described.

When a message is received, message display setting module70specifies the attached file to be executed and displayed in the specified display areas at the display unit simultaneously with the main text.

The areas may also be divided up and down or left and right. The user may input, in advance, the display-specifying data for dividing the display area up and down, or left and right, for the purpose of convenient confirmation of the message. The display-specifying data directly input by the user are stored in the memory.

When a message is received, display setting module70detects the display-specifying data from the memory and allots the display areas of the main text and/or the attached file of the message in accordance with the display-specifying data input in advance by the user.

Input of the display-specifying data may be carried out using a predetermined input menu, and then inputting set values for prepared items by manipulating of the key input unit relative to the menu.

In the aforementioned example, when two or more attached files are included in the message, the number of attached files (corresponding to the number of areas allotted to display the attached files) are displayed and the other attached files are sequentially and rotationally displayed.

For example, when the message includes four attached files and the number of areas which are allot to display the attached files is two, two attached files are first displayed and the other two attached files are then sequentially displayed.

When the user first confirms two displayed attached files and then press a predetermined key, the other attached files are sequentially displayed.

In the mobile phone shown inFIG. 3, the main text of the message is displayed in an area indicated by reference numeral10and the attached files are displayed in areas indicated by reference numerals20and30. That is, when two or less attached files are included in the message, all the attached files are simultaneously displayed in the display unit.

When two attached files are displayed and when the message includes three or more attached files, two attached files may be displayed in the areas indicated by reference numerals20and30and the other attached files may be sequentially and rotationally displayed in the area indicated by20or30automatically or in response to press of a predetermined key by the user.

In the areas which are set to display the attached files, image file may be displayed in the area indicated by20and a text file may be displayed in the area indicated by30.

The other attached file is displayed in the area indicated by20or30in the following way. That is, the next attached file may be displayed in the corresponding area with a predetermined cycle, or the next attached file may be displayed in the corresponding area in response to press of a key or icon indicating display of the next attached file by the user. The cycle when the next attached file is rotationally displayed may be set on the basis of the display-specifying data input by the user.

The attached file may include text files, image files, moving picture files, sound files, etc., and when two or more image files are included as the attached files it can be set to display the respective image files in the same size.

When a sound file is included as the attached file, the sound file may be executed at the point in time when a key indicating confirmation of the message is pressed. Alternatively, when the execution time of the sound file is set after the message is confirmed in accordance with the display-specifying data, the sound file may be executed in the set execution time after press of the key indicating confirmation of the message.

FIG. 3illustrates an example of the areas in which the main text and the attached files of the message may be displayed in the display unit. It can be seen from this figure that the areas can be changed.

FIG. 4shows a message display process in a mobile terminal according to the present invention.

First, a user account is established to transmit and receive messages in a mobile phone, and display-specifying data are input.

When a message arrives at a message address of the account (S10), the message display setting module detects attached files included in the message (S20), and also detects the number of display areas allotted by display-specifying data stored in the memory50.

The message display setting module converts the message into SMIL file, such that if a number of attached files exceeds that of displaying area to display the attached file, the number of attached files which can be displayed in the display areas in the display unit is displayed. Then, the other attached files may be sequentially and rotationally displayed.

When an attached file is displayed in a corresponding area, scroll bars may also be displayed as shown inFIG. 3, and the user can confirm the attached files by moving the scroll bars up and down or left and right.

The message display setting module also determines whether a main text exists, so as to specify the area in which the main text of the message is to be displayed in the display unit (S40).

When the main text of a text type exists, the display area for the main text is additionally specified (S50). The main text may be displayed in the area of the display unit set to display the main text.

As described above, when the key indicating the confirmation of the received message is pressed (S60) after the display areas for the main text and the attached files of the message, the main text and the attached files are displayed in the corresponding areas of the display unit40(S70). The main text and the attached files of the message can therefore be simultaneously displayed in a screen of the display unit thereby making it possible to more easily confirm the message.

Also, when a message is confirmed using a mobile phone according to the present invention, the main text and attached files of the message are displayed in the specified areas of the display unit, so that it is possible to confirm the message at first glance.

In addition, when the main text of the message is related to the attached files, it is possible to more easily confirm the message.
