Description

How to edit special characters in mobile communication terminal

The present invention relates to a method for editing a mobile communication terminal, and more particularly, to a method for facilitating the input of similar characters when editing an alphabet.

In general, mobile terminals have various functions such as schedulers as well as telephone numbers. Thus, in order to use such a function, a user may need to input various characters. For example, entering the name of a telephone number. By the way, when supporting the input of characters of various languages as well as the conventional English, it is necessary to input a number of special characters in addition to the basic 26 characters. So, it is necessary to input special characters such as "ε", "Ё", "ё", but conventionally, there was no function for inputting such special characters.

Accordingly, an object of the present invention is to provide a method for facilitating the input of special characters.

In order to achieve the above object, the present invention provides a special character input method of a mobile communication terminal having a memory for storing character data consisting of a plurality of representative characters and one or more special characters corresponding to each of the representative characters, A first step of checking whether an editing mode for inputting a character is selected, a second step of checking whether a representative character is designated if the editing mode is selected, and a second step of checking whether the designated representative character is selected if the representative character is designated; And a fourth step of checking whether a special character input mode is selected when the representative character is not selected, and displaying a special character corresponding to the stored representative character when the special character input mode is selected. The fifth step of checking whether one of the special characters is selected; Claim 3 is characterized in the process of or constituted by any of claim 6 and storing the representative character or a special character selected in said fifth step.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Specific details appear in the following description, which is provided to aid a more general understanding of the present invention, and it should be understood by those skilled in the art that the present invention may be practiced without these specific details. It will be self explanatory. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic block diagram of a mobile communication terminal according to an embodiment of the present invention.

The control unit 100 of the mobile communication terminal controls the overall operation of the terminal and performs a control operation for editing special characters according to the present invention. The key input unit 110 includes a plurality of numeric keys and function keys for performing various functions, and outputs key data to the controller 100 by an external operation. The display unit 120 is a display device such as a liquid crystal display (LCD). The display unit 120 displays a state of a mobile communication terminal or a progress of a program under the control of the controller 100. The memory 130 includes a ROM that stores an operating program, an electrically programmable EEPROM, and a RAM. Memory 130 has a character data storage area 131 for storing data consisting of a plurality of representative characters and one or more special characters corresponding to each of the representative characters according to the present invention. The signal processor 140 modulates a voice signal input from a microphone and converts the voice signal into voice data, demodulates the voice data input from the RF unit 150 into a voice signal, and outputs the voice signal through a speaker. . In a mobile communication system using a conventional CDMA (CODE DIVISION MULTIPLE ACCESS) method, the signal processor samples a voice input through a microphone, converts it into a PCM modulated signal, and converts it into a voice coded signal. The speech encoded signal is subjected to a process such as orthogonal modulation again. The RF unit 150 is controlled by the controller 100 and transmits and receives various data to and from the base station through the antenna. In the CDMA method, the quadrature-modulated signal is modulated into an analog signal, and the modulated analog signal is loaded on a high frequency radio signal and transmitted to the base station through an antenna.

2 is a control flowchart for editing an alphabet according to an embodiment of the present invention.

In step 200, the controller 100 determines whether the edit mode is selected through the key input unit 110. The editing mode refers to a mode requiring text input, for example, storing a phone number or creating a scheduler. Table 1 shows an example.

"◀ ▶" in Table 1 indicates the position of the cursor. If the edit mode is selected as described above, it is checked in step 210 whether a representative character is designated. The designation of the representative character refers to designation of a character by moving a cursor at the request of a user. Therefore, when the user moves the position of the cursor by using the direction key of the key input unit 110 or the like to enter the letter "N" after "MOO", the representative character is designated. In step 220, the controller 100 checks whether data for selecting the corresponding character, which is the designated representative character, is input from the key input unit 110. If the key data is input, the process proceeds to step 260, otherwise proceeds to step 230. In the above case, a plurality of representative characters are displayed on the display unit 120 so as to be selected by the user. However, the present invention can be applied to selecting a character by pressing a specific key. For example, by pressing the "1" key, "A", "B", and "C" can be specified in a toggle mode. If a certain time elapses or any other key is pressed, the character is not applied. It is possible. In step 230, the controller 100 checks whether a mode for receiving a special character is selected. If the special character input mode is selected, go to step 240; otherwise, go to step 270. In step 240, the control unit 100 displays the corresponding special character through the display unit 120. The displayed special character becomes a special character stored in connection with the corresponding character selected in step 220. If the user selects the representative character of "E" and the special character input mode can be shown as Table 2 below.

Therefore, the memory map of the data stored in the character data storage area 131 is made as shown in Table 3 below.

Address One ..... 5 ..... Representative A ..... E ..... Special Characters α ..... ε ..... ..... ..... ё ..... ..... ..... Ё ..... ..... ..... ..... .....

In step 250, the controller 100 checks whether key data for selecting a special character is generated. If the data has been generated, the process proceeds to step 260, otherwise proceeds to step 270. In step 260, the controller 100 stores the representative or special character selected in step 220 or 250 in the memory 130. In step 270, the control unit 100 checks whether end data is input. If the end data is generated, the program ends. If no end data is input, the process returns to step 210.

Briefly describing the present invention, a user selects a representative character input mode first and then selects a special character input mode in a state in which character data consisting of a plurality of representative characters and at least one special character is stored in each of the representative characters. This facilitates the input of special characters during character editing.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention stores text data consisting of a plurality of representative characters and at least one special character in each of the representative characters, and allows the user to select the representative character input mode first and then select the special character input mode again. Special characters can be easily entered during editing.
