TEXT MESSAGE EDITING METHOD FOR MOBILE COMMUNICATION TERMINAL}

1 is a screen example showing a conventional text message editing method.

Figure 2 is an exemplary screen showing a text message editing method of an embodiment of the present invention.

Figure 3 is a flow chart showing the operation of the embodiment of the present invention.

The present invention relates to a text message editing method of a mobile communication terminal, and more particularly to a text message editing method of a mobile communication terminal which increases the editing speed by deleting a part of an input text message by a line unit rather than a character unit. will be.

As the use of mobile communication terminals is becoming more common, the necessity of information transmission using a mobile terminal is gradually increasing. In particular, the broadcast transmission function of a short message service (SMS) or a long message service (LMS), which can deliver the same information to multiple users at the same time, is more convenient and useful due to various user interface improvements. In particular, when the mobile phone terminal stores a phone book function for storing contact information, the group management function, which has emerged, is enhanced, and a message can be sent to all members of a group by designating a group and then sending a message. Therefore, it is easy to deliver information to a large number of users without the trouble of inputting or retrieving phone numbers to be delivered. In addition, as the group management function is more actively and complexly improved (cross grouping, selective grouping, etc.), the application flexibility is increased, and more users are using the broadcast transmission of short or long messages.

In addition to using such a text message, various functions that require the user to input a multi-line sentence by directly operating the keypad, such as writing and storing a simple memo content or writing a schedule content, are also provided.

However, as it is known, a task of making a sentence by inputting letters and symbols using a limited keypad of a mobile communication terminal is not very easy, and even if a little mistake is made, unwanted characters or symbols are input. Therefore, it is easy to make a case where editing is necessary to correct a typo, and it is often a case of modifying and reusing some of the existing contents to reduce the input time.

The only way to delete the wrong part of the string editing operation is to repeatedly enter the "Erase" key and erase the previous characters one by one.

FIG. 1 is an exemplary view showing a method of deleting a character used when inputting and editing a character. As shown in FIG. 1A, when a user writes a sentence by inputting a keypad, the character is assigned to the "erase" key when the user wants to erase a character in a certain area. If any key is pressed, the front letter of the part where the cursor is located is deleted as shown in FIG. 1B, and the cursor is moved by the deleted letter to wait for another input.

If the letters to be deleted are entire one line, the "Delete" key can be erased as many times as the number of the letters of the line to be erased to erase the entire line as shown in FIG. 1C.

Therefore, if there are many letters to be erased, the "Erase" key has to be entered several times, which is cumbersome and time consuming.

As described above, the method of deleting a desired string among the string editing methods of the conventional mobile communication terminal has to press a predetermined "Erase" key as many times as the number of letters to be erased. There was a problem that took a long time.

In view of the above problems, the present invention adds a menu for erasing an entire line in which a cursor is located on a character input screen, or assigns the function to a predetermined key to erase a large amount of character strings at a faster time, thereby greatly improving editing time. An object of the present invention is to provide a text message editing method of a mobile communication terminal.

According to an aspect of the present invention, there is provided a method of inputting a character or a symbol or displaying an existing character string by executing a character string creation or editing function of a mobile communication terminal; Moving the cursor to the row to be deleted; Specifying one line deletion using a menu or a shortcut key includes deleting all characters of the line where the cursor is located.

Deleting all the characters of the row where the cursor is located comprises: determining the position of the character designated by the cursor in a memory storing the displayed character; Identifying a memory start address and an end address corresponding to a display line in which the identified character is located and erasing all contents of the memory; The method may further include moving all memory contents after the erased memory area based on the start address of the erased row and updating the display unit contents using the modified memory contents.

Hereinafter, with reference to the accompanying drawings, the present invention configured as described above will be described in detail.

FIG. 2 is an exemplary view illustrating a method of operation according to an exemplary embodiment of the present invention. As shown in FIG. 2A, a user inputs a character string or reads an input message. If you want to delete the information, press the menu key to display the menu selection screen as shown in FIG. 2B and select "one line deletion" from the provided submenus.

When the "single line" menu is selected as described above, as shown in FIG. 2C, all rows in which the cursor is positioned are deleted, and the cursor is positioned at the end of the previous row, that is, the front of the deleted row.

In the illustrated case, the last row is deleted, and when the middle row is deleted, the next row of the deleted row is moved to the deleted row portion.

In the above embodiment, the menu is used to select “one line erase”, but a predetermined key may be assigned to operate as “one line erase” when the corresponding key is pressed. In addition, it is possible to designate a hot key (or a soft key) so that when the existing "erase" key is pressed for a long time, it can operate as "one line erase".

FIG. 3 is a flowchart illustrating an operation of an embodiment of the present invention, which illustrates an operation when the user selects the "one line" function as described above (using a menu or a hotkey) when composing a message.

When the user selects "single line", the mobile terminal determines the position of the character corresponding to the position of the cursor. In general, a message is created by allocating a predetermined memory area to a message area, and writing a character code or data to the message area by user input or calling existing content. In addition, since the memory area is configured to correspond to the screen, a predetermined area of the memory has a size corresponding to the screen, and addresses having a predetermined rule correspond to each row. That is, address 0 may correspond to the first letter of the first line, and address 16 may be defined to correspond to the first letter of the second line.

Therefore, if the character address of the part where the cursor is located is known, the start address and the end address of the row where the cursor is located can be known, and thus all the corresponding memory contents can be deleted.

If character data exists after the erased memory area, the memory data is updated by sequentially moving them based on the start address of the erased row. The screen is displayed again using the updated memory data.

If necessary, the position of the cursor may be moved to the beginning of the erased display line or to the last of the previous line of the erased display line to correspond to subsequent editing by the user.

As described above, when the editing method of the present invention is used, it is possible to quickly erase a certain character string during character editing without additional hardware changes, thereby reducing the editing time without the need for repetitive key input. Will be.

As described above, the text message editing method of the text mobile communication terminal of the present invention adds a menu for erasing the entire line where the cursor is located on the input screen, or assigns the function to a predetermined key, thereby increasing the volume in a faster time. Delete the string of characters to greatly reduce the editing time, thereby improving the user's convenience.
