Accordingly, an object of the present invention is to provide a method for performing a file search with one hand in a mobile communication terminal.

Another object of the present invention is to provide a method for performing a file search by mapping a specific search mode to a specific key in a mobile communication terminal.

According to a first aspect of the present invention for achieving the above object, a method for searching a file with one hand in a mobile terminal capable of searching for a file includes: mapping modes for searching for a file to specific keys; When a specific key mapped with file search modes is input, the method includes checking a file search mode mapped to the specific key and executing the identified search mode.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when 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.

Hereinafter, a description will be given of a technique for searching a file with one hand in a mobile communication terminal capable of file searching. In the following description, an upper directory search key, a more search key, a lower directory search key, and a file search key may be set to perform a file search with one hand. The search keys may be navigation keys (◀ / ▶ / An example of what is implemented using () is described.

2 shows a block configuration of a mobile communication terminal according to the present invention. In the following description, the mobile communication terminal is a personal data assistant (PDA), a smart phone, a cellular phone, a personal mobile communication phone (PCS: Personal Communication System) capable of file searching, It will be described with a general configuration of the mobile communication terminal, including all the IMT2000 (International Mobile Telecommunication 2000) terminal.

Referring to FIG. 2, first, a controller (MPU: Micro-Processer Unit) 200 controls the overall operation of the mobile communication terminal. For example, it performs processing and control of data management functions as well as voice calls and data communications, and in addition to the usual functions, the upper directory search key, more search key, lower directory search key, and file search key set in accordance with the present invention. Processes a function to perform a file search according to the input of. Therefore, in the following description, description about the process and control of the normal control part 200 is abbreviate | omitted.

The read only memory (ROM) 202 stores microcodes of programs and various reference data for processing and control of the controller 200. In particular, according to the present invention stores a program for performing a file search according to the input of the set search key (eg, upper directory search key, more search key, lower directory search key, file search key). For example, when the upper directory search key is input, the file search program moves to the upper directory of the currently selected directory, and when the more search key is input, folders or files included in the currently selected directory. Files or folders that are not displayed on the display unit 210 are displayed. In addition, when the sub directory search key and the file search key are input, the sub directory search file and the file search key are moved to the sub directory or file list included in the currently selected directory.

A random access memory (RAM) 204 is a working memory of the controller 200 and stores temporary data generated during execution of various programs. The flash ROM 206 stores various updatable archiving data such as a phone book, an outgoing message, and an incoming message.

Key pad 208 is a numeric key buttons of 0-9, menu button (menu), cancel button (clear), confirmation button, call button (TALK), end button (END), Internet access button, A plurality of function keys such as navigation key (or direction key) buttons (▲ / ▼ / ◀ / ▶) are provided, and key input data corresponding to a key pressed by the user is provided to the controller 200.

The display unit 210 displays status information generated during the operation of the mobile communication terminal, a limited number of characters, a large amount of video and still images, and the like. The display unit 210 may receive data by a user's manipulation using a touch screen.

The codec (Coder-Decoder) 212 connected to the control unit 200 and the speaker 216 and the microphone 214 connected to the codec 212 are voice input / output blocks used for phone calls and voice recording. . The codec 212 converts the PCM data provided from the controller 200 into an analog voice signal, transmits the same through the speaker 216, and converts the voice signal received through the microphone 214 into PCM data. It provides to the control unit 200.

In addition, the RF unit 220 reduces the frequency of the radio frequency signal received through the antenna 218 to the baseband processor 222 and provides the baseband signal from the baseband processor 222. The frequency is raised and transmitted through the antenna 218. The baseband processor 222 processes a baseband signal transmitted and received between the RF unit 220 and the controller 200. For example, in the case of transmission, the channel coding and spreading of data to be transmitted are performed, and in the case of reception, the function of despreading and channel decoding of the received signal is performed. To perform.

3 shows a procedure for searching for a file in a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 3, first, in step 301, the controller 200 determines whether a file search mode is selected by a user's manipulation (eg, a key input or an input using a stylus). If the file search mode is not selected, the controller 200 proceeds to step 313 to perform a corresponding mode (eg, a standby mode).

If the file search mode is selected, the control unit 200 proceeds to step 303 and displays a file search window on the display unit 210. For example, as illustrated in FIG. 4, a file search window having a star structure is displayed. In the file search window of the molding structure, the home / root directory is located at the center, and the upper directory search is performed by a search key operation of up (▲), down (▼), left (◀) and right (▶). 401 (e.g., ◀ key input), mower search 403 (▶ key input), subdirectory search 405 (▲ key input) and file search 407 (▼ key input) mode can be switched to . In addition, although the subdirectory is displayed at the upper part and the file is displayed at the lower part as shown, the subdirectory and the file may be mixed.

In operation 305, the controller 200 determines whether the upper directory search key ◀ is input.

If the upper directory search key is input, the controller 200 proceeds to step 307 and checks whether a higher directory exists than the currently selected directory. If the upper directory exists, the controller 200 proceeds to step 309 and moves to the upper directory of the currently selected directory. When the user moves to the upper directory, the file search window is reconfigured using the lower directories and files included in the upper directory.

If the upper directory does not exist, the control unit 200 proceeds to step 311 and displays a warning message indicating that the upper directory does not exist and thus cannot be moved. Thereafter, the controller 200 ends the present algorithm.

On the other hand, if the upper directory search key is not input, the controller 200 proceeds to step 321 and searches whether the more search key ▶ is input.

If the more search key is input, the controller 200 proceeds to step 323 and displays directories or files not displayed on the current screen among subdirectories or files included in the currently selected directory. For example, if the number of directories or files that can be displayed on one screen is 10, and if the number of subdirectories or files included in the currently selected directory is 20, the first 10 directories or files are displayed first, and the mower When the search key is input, the remaining ten directories or files that were not displayed are displayed on the display unit 210.

In operation 325, the controller 200 determines whether an upper directory search key is input. If the upper directory search key is not input, the controller 200 ends the present algorithm.

If the upper directory search key is input, the controller 200 proceeds to step 327 and moves to the previous screen. That is, in the more search mode, the upper directory search key is used as the previous screen moving key. Here, the upper directory search key operates as the previous screen moving key and moves to the first screen, that is, the first displayed screen from the currently selected directory, to perform the upper directory search mode again. Thereafter, the controller 200 ends the present algorithm.

On the other hand, if the mode search key is not selected, the controller 200 proceeds to step 331 and checks whether a lower directory search key ▲ is input.

If the subdirectory search key is input, the controller 200 proceeds to step 333 and moves to the subdirectory list included in the currently selected directory. In this case, the navigation left / right keys (◀ / ▶) set as the upper directory search key and the more search key perform a general navigation key operation. Here, in order to move into a specific directory, a confirmation key may be input to move into the selected specific directory. In addition, when the navigation down key (▼) is input in the sub directory search mode, the home / root directory is switched.

Thereafter, the controller 200 ends the present algorithm.

If the lower directory key is not input, the controller 200 proceeds to step 341 and checks whether a file search key (▼) is input. If the file search key is not input, the controller 200 returns to step 305.

If the file search key is input, the controller 200 proceeds to step 343 and moves to the file list included in the currently selected directory. In this case, the navigation left / right keys (◀ / ▶) set as the upper directory search key and the more search key perform a general navigation key operation. In addition, after moving to a desired file using a navigation key and inputting a confirmation button, a corresponding executable file corresponding to the type of the file is started. For example, if the selected file has an executable file extension such as exe, the executable file can be directly executed. If the selected file has an extension such as doc, txt, or hwp, a corresponding viewer is executed. When the navigation down key (▼) is input in the sub directory search mode, the home / root directory is switched.

Thereafter, the controller 200 ends the present algorithm.

As described above, when searching for a file using the upper directory search key (◀), the mower search key (▶), the lower directory search key (▲), and the file search key (▼), access of O (log n) is performed. Take time. For example, if a file to be searched in the currently selected directory is included in the parent directory, enter the parent directory search key (◀) to move to the parent directory, and if the directory or file to be selected is not displayed, Enter a search key to display undisplayed directories or files.

In addition, in the case of the currently displayed directory or file, a search using the sub directory search key or the file search key can be performed, thereby reducing the file access time.

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 determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, a file is searched by specifying a search key (upper directory search key, more search key, lower directory search key, file search key) having different functions in a mobile communication terminal capable of file search, thereby providing information display space. In this limited situation, you can easily perform a multi-layered search with one hand and reduce the file search time.
