The present invention relates to a character input method in a mobile communication terminal, and more particularly, to an automatic character input method using a shortcut key when inputting a character in a mobile communication terminal.

At present, three domestic telecommunication companies, radio research institute and Korea Information and Communication Technology Association have gathered the opinions of various contents companies, handset manufacturers and other related companies to create Wifi, a terminal middleware standard platform. Such a Wi-Fi is a standard standard for providing an application execution environment installed in a mobile communication terminal and downloaded through the wireless Internet. Wifi's supported languages support both C and Java at the same time, and can be implemented independently of the hardware. For example, Wi-Fi is designed so that CPU, LCD, and memory can be executed and ported regardless of the terminal hardware or operating system (OS) used by the terminal. In particular, WIPI2.0 has been adopted to support J2ME (JavaTM2Platform, Micro Edition). J2ME is a platform created by SUN, a lightweight virtual machine that supports a variety of embedded devices and tools in a variety of environments to meet the needs of users. Wifi also includes a security specification that prevents applications from accessing private carrier or device manufacturer secrets or terminal user personal information at will. Recently, most of the terminals produced in Korea are equipped with the same Wipi, and the Wiki is also mounted on terminals exported to overseas. In addition, as Wi-Fi is also installed in the Global European System for Mobile Communications (GSM) series, the spread of Wi-Fi is expected to spread worldwide.

A user must go through a user authentication process in order to access the WiPie application from a terminal capable of performing such a WiPie application. For example, to access cyworld, an online community site, a user first runs a Wi-Fi application. Then, as illustrated in FIG. 1, the ID input window 102 and the password input window 104 are displayed. Then, the user inputs the user's ID one by one in the ID input window 102 by using the keys of the terminal. Next, the user inputs the password using the key of the terminal in the password input window 104, and after the user authentication, if the authentication is successful, the user can use the application.

As described above, the method for accessing the conventional Wi-Fi application requires the user to directly input the ID input window 102 and the password input window 104 shown in FIG. 1 by using the keys of the terminal.

Accordingly, the present invention provides a method for automatically inputting a string that can store the ID or password string in advance corresponding to a shortcut key when inputting an ID and a password for performing the WIPI application, and automatically input the corresponding string using the shortcut key.

In accordance with another aspect of the present invention, there is provided a character input method using a shortcut key in a terminal, wherein at least one key input is input in a state in which a key for capturing a character is input in a Wi-Fi application mode. When capturing a character and the key for capturing the character is released, a process of storing the captured characters into a string and corresponding to the shortcut is stored in the shortcut set table, and inputting a shortcut in a state where a key for automatic character input is input. And when the key for automatic input of the character string is released, extracting a character string corresponding to the input shortcut key from the shortcut key table and displaying it on the screen.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

The present invention proposes a method of automatically storing a character string for automatic input in response to a shortcut key and automatically inputting the corresponding character string according to the user's input of a shortcut key when executing the Wi-Fi application.

Then, the operation of each of the internal components of the terminal in the terminal having the Wi-Fi application function will be described. An operation of each of the internal components of the terminal performing a function of automatically inputting a letter using a shortcut key according to the present invention will be described with reference to FIG. 2.

Referring to FIG. 2, the controller 200 processes and controls typical functions such as a phone call and data communication, and executes a Wi-Fi application according to an embodiment of the present invention, which will be described later. This function automatically inputs the saved string into the text input window. The controller 200 stores the shortcut keys and the captured characters in the shortcut key collection table of the memory unit 206. Referring to this process through an exemplary diagram showing information transmitted and received between layers when storing a character corresponding to the shortcut key of FIG. 6, when the OEM (Original Equipment Manufacturer) layer 604 detects a key event, the controller 200 Transmits the character corresponding to the key to the HAL (Handset Adapter Layer) 602. At this time, in general, since the ID or password is composed of a plurality of characters, the user inputs a plurality of characters in order to store the string in response to the shortcut key. Therefore, the key event occurs as many characters as the user inputs the ID or password. Subsequently, the controller 200 captures the characters corresponding to the keys sequentially transmitted from the OEM to the HAL 602, generates a plurality of captured characters as a character string, and temporarily stores the captured characters in the memory unit 206. send. In addition, the controller 206 extracts a character string corresponding to a shortcut key input according to a shortcut key input from the shortcut key table of the memory unit 206 and displays the string through the display unit 212. This process will be described through an exemplary view showing information transmitted and received between layers when a character string corresponding to the shortcut key of FIG. 7 is displayed. First, when the OEM layer 704 detects a shortcut key event, the controller 200 transmits a shortcut key value corresponding to the shortcut key to the HAL.

In addition, the controller 200 may edit a character string stored in the shortcut key table in response to the shortcut key of the memory 206.

The RF module 202 transmits and receives a radio signal with a mobile communication base station through an antenna, and modulates a signal to be transmitted from the control unit 200 through a baseband processor 204 to convert an RF signal into an antenna. And demodulates the RF signal received through the antenna and provides the demodulated RF signal to the controller 200 through the baseband processor 204.

The baseband processor 204 processes baseband signals transmitted and received between the RF module 202 and the controller 200.

The memory unit 206 stores various updateable storage data such as programs, reference data, and phone number information for processing and control of the controller 200, and is provided as a working memory of the controller 200. In particular, the memory unit 206 stores a temporary storage space for capturing and temporarily storing each character input when storing a character string, and a shortcut set table for storing the captured character string and a shortcut value corresponding thereto. At this time, the shortcut key table stores the shortcut key value and the key captured character string in the memory unit 206.

The key input unit 208 corresponds to menus, selections, calls, erases, power / shutdowns, and volumes (0, 9), *, # keys, and various functions of the corresponding mobile communication terminal. It is provided with a plurality of function keys, such as adjusting the volume and provides the control unit 200 with key input data corresponding to the key pressed by the user. In general, the volume control key is used as a key for volume control and direction key functions, but in the present invention, the volume control key is used as a function key for storing and outputting a character string corresponding to a shortcut key. Among the volume control keys, the volume up key is used as a key for capturing characters, and when there is a key input for character input while the volume up key is input, the character corresponding to the input key can be captured. In addition, when the volume up key is released, it is used as a key to perform a function of storing a string of captured characters in a shortcut set table. In addition, the volume down key is a key for automatic text input. When a specific shortcut key is input while the volume down key is input, a volume string corresponding to the shortcut key is extracted from the shortcut set table, and the volume down key is extracted when the volume down key is released. Character strings can be displayed on the terminal screen. In an embodiment of the present invention, the volume control key is used as a function key for storing and outputting a character string corresponding to a shortcut key. However, a separate key for such a function may be provided, and a specific key other than the volume control key is already provided. You can also assign these functions to keys.

The voice processor 210 processes a voice signal input or output to the mobile communication terminal for a phone call, voice recording, voice output, and the like.

The display unit 212 displays various image information and images stored in the reception or memory unit 206 on the screen under the control of the controller 100.

Then, in the terminal configured as shown in FIG. 2, the control process of storing a character string corresponding to a shortcut key for automatic character input, automatically outputting the character string using the shortcut key, and editing the stored character string is described with reference to FIGS. 3 to 5. Let's take a look.

Next, a control process for storing a character string corresponding to a key input by a user using a volume up key in the Wippy application mode will be described with reference to FIG. 3.

In step 300, if there is a selection for the user to perform the Wipy application mode, the controller 200 executes the Wipy application mode. Then, in step 302, if there is a key input for character input while the volume up key is input through the key input unit 208, the controller 200 proceeds to step 304 to capture a character corresponding to the input key value and to store the memory. Temporarily stored in the unit 206. In step 306, the controller 200 determines whether the volume up key is released. In this case, releasing the volume up key means releasing the volume up key held by the user. If the volume up key is released in step 306, the control unit 200 proceeds to step 308, otherwise proceeds to step 304 and continues to detect and capture characters input through the key input unit 208, and then the memory unit. Temporarily store at 206.

In step 306 to step 308, the controller 200 stores the captured character string that is temporarily stored in the memory unit 206 in the shortcut key collection table of the memory unit 206. Thereafter, in step 310, if there is a key input for terminating the Wi-Fi application through the key input unit 208 from the user, the controller 200 terminates the Wi-Fi application mode. That is, the user may input a predetermined plurality of characters for automatic input while the volume up key is input. For example, when a user inputs a key for character input while the volume up key is input, the character corresponding to the key for character input is captured and temporarily stored. In this case, the characters inputted before the volume up key is released are stored by gaps. Then, when the volume up key is released, all captured characters are composed of a string, and the string is stored in the shortcut set table corresponding to the shortcut. The above-mentioned shortcut key may be configured in various forms. For example, the shortcut key may be composed of keys such as numeric keys, alphabet / Korean keys, and the like. In addition, as a method of storing a shortcut key corresponding to a string in the shortcut set table, the captured string may be sequentially stored in a sequence of numbers from 0 to 9, alphabets of a to z or alphabetical order of a to ㅎ. In addition, the user can designate and save the captured string as a shortcut key.

Next, a control process for automatically inputting a string corresponding to the input shortcut key according to the shortcut key input will be described with reference to FIG. 4.

In step 400, if there is a selection for the Wi-Fi application from the user, the control unit 200 executes the Wi-Fi application mode. Thereafter, in step 402, if the shortcut key is input while the volume down key is input through the key input unit 208, the control unit 200 proceeds to step 404 to check whether the volume down key is released, and then the volume down key If it is released, it proceeds to step 406, otherwise, it waits for the volume down key release in step 404.

In step 406, the controller 200 extracts a string corresponding to the input shortcut key from the shortcut key table, and then proceeds to step 408 to display the extracted string in a corresponding region in the text input window. Then, if there is a key input for terminating the Wi-Fi application through the key input unit 208, the control unit 200 ends the Wi-Fi application mode.

Next, a control process for editing the shortcut key table will be described with reference to FIG. 5.

Referring to FIG. 5, in step 500, the controller 200 maintains a standby state. Thereafter, if there is a key input for selecting a shortcut editing menu through the key input unit 208 in step 502, the process proceeds to step 504. In step 504, the controller 200 displays a shortcut key editor 800 for editing a pre-stored shortcut key as shown in FIG. 8A through the display unit 212. Thereafter, the user may select one of submenus composed of an ID or a password displayed in the shortcut editor 800, and when the submenu is selected, the terminal displays a string corresponding to the submenu on the screen. In this case, an example of the display screen may be illustrated in FIG. 8B. Thereafter, the controller 200 proceeds to step 506. If there is a key input for editing through the key input unit 208, the controller 200 proceeds to step 508. In operation 508, the string edited by the user is stored as a string corresponding to the shortcut key of the shortcut key table. In operation 510, if there is a key input for ending the shortcut editing menu through the key input unit 208, the controller 200 ends the shortcut editing menu.

In the foregoing description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, in the embodiment of the present invention, the shortcut key has been described as a numeric key, but all keys provided in the terminal other than the numeric key can be used as the shortcut key. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention stores a frequently used string such as an ID or a password in response to a shortcut key when the WiPi application is executed. Therefore, when inputting a character for user authentication for accessing the Wi-Fi application, the user may input a character string at a time using only a shortcut key instead of inputting the character one by one. Therefore, when executing the Wi-Fi application, it is possible to save time for inputting a string for user authentication and to eliminate the possibility of typos.
