Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a schematic block diagram of a mobile communication terminal for performing a method according to the present invention, which includes a key input unit 10, a control unit 20, a memory unit 30, and a display unit 40.

As shown, the key input unit 10 is composed of a soft-key 12 and a search key 14 according to the present embodiment, and various key signals, for example, numeric keys for inputting a telephone number. Signal, generates a character key signal for name input. The soft key 14 in the key input section 10 is a toggle type key input means, which allows input of letters and numbers as a string and outputs them to the screen. For example, when the soft key 12 is pressed once by the user, the user enters a number input mode for inputting a number. When the soft key 12 is pressed twice, the user enters a character input mode for inputting a character. Can be.

The search key 14 in the key input section 10 is a key input means provided on a normal terminal, and inputs of desired search data of the user, for example, predetermined number (12 ××) or character data (kim ××). It is used as a means to initiate a search after completion.

The control unit 20 according to the present invention performs overall control of the mobile communication terminal, and read and retrieve the telephone number data stored in the memory unit 30 to be described later, in accordance with the key signal of the key input unit 10 described above, and input Control to output the character data corresponding to the key signal to the outside.

The memory unit 30 stores various user information, namely, name and telephone number data, and is read out by the control unit 20 described above. The memory unit 20 is the same as the configuration and function of the memory unit provided in a conventional mobile communication terminal, a detailed description thereof will be omitted.

The display unit 40 may be configured as a display window provided on a mobile communication terminal, for example, a liquid crystal display (LCD). The display unit 40 may store a predetermined letter or number, for example, a name, a phone number, or the like, under the control of the controller 20. Displays the place (address), etc.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figure 2 attached to the phone number search process of the mobile communication terminal according to a preferred embodiment of the present invention will be described in detail.

Prior to the description, the method according to the present invention is characterized in that not only a number and a letter input can be performed simultaneously with the same single search engine, but also a phone number, a name, and a storage location (address) search are performed simultaneously.

As shown, in step S100, the control unit 20 determines whether there is a key input, that is, an input of the soft key 14.

As a result of the determination in step S100, if there is an input of the soft key 14, the controller 20 proceeds to step S102 to determine whether the current terminal mode is a numeric input mode or a character input mode. Judgment in this step (S102) is based on the above-described functional characteristics of the soft key 14, the mode setting can be switched according to the primary input, secondary input of the soft key 14, this fact is Those skilled in the art will readily appreciate, and a detailed description thereof will be omitted.

On the other hand, if it is determined in step S102 that the input of the soft key 14 is a mode setting key input for numeric input, the control unit 20 proceeds to step S104 to switch the terminal to the numeric input mode, and the key When the input of the numeric data from the input unit 10 is completed and the search start signal is applied from the search key 12, it is determined whether the input numerical data is within a storage location, that is, within the address range previously stored in the memory unit 30. . In this case, the display screen in the numeric input mode of the terminal, that is, the text output screen driven by the display unit 40 may be represented as shown in FIG. 3A.

As a result of the determination in step S104, if the input numerical data is within the address range, the flow advances to step S106, but if the input numerical data exceeds the address range, the control unit 20 proceeds to step S108. In step S106, the control unit 20 searches for a storage location matching the numeric data input from the key input unit 10 through the memory unit 30, and then proceeds to step S108 to perform the key input unit 10. The phone number matching the numeric data input through the memory unit 30 is searched. That is, in steps S104 to S108, when the input numerical data exceeds the address range stored in the memory unit 30, for example, the previously stored address range is "000 to 199" and the input numeric data is entered. In case of "1234", only the telephone number is searched, but when the input numeric data is within the address range stored in the memory unit 30, for example, the pre-stored address range is "000-199" and the input numeric data is "123". "If it is characterized by searching the storage location and the phone number at the same time.

After performing such a search process, the controller 20 proceeds to step S114 to determine whether there is telephone number data matching the input numeric data.

As a result of the determination in step S114, if there is telephone number data matching the input numeric data, the control unit 20 proceeds to step S116 and displays the telephone number data according to the search result on the display unit 40. .

However, if the phone number data matching the input numerical data does not exist as a result of the determination in step S114, the control unit 20 proceeds to step S118 and the data matching the search expression input by the user is stored in memory. Characters and sound sources indicating that they do not exist in the unit 30 are output. These characters are, for example, "no matching phone number." Or "it is an empty street."

On the other hand, as a result of the determination in step S102, if the input of the soft key 12 is a mode setting key input for inputting letters or numbers / characters, the control unit 20 proceeds to step S110 to switch the terminal to letters or numbers. It is switched to the / character input mode, and it is determined whether the input of the character or number / character data from the key input unit 10 is completed and the search start signal is applied from the search key 14. In this case, the display screen in the character input mode of the terminal, that is, the text output screen driven by the driving of the display unit 40 may be represented as shown in FIG. 3B, and the display screen in the number / character input mode is shown in FIG. 3C. It can be expressed as:

As a result of the determination in step S110, when a search start signal is applied from the search key 14, the control unit 20 proceeds to step S112, where the control unit 20 matches the letter or number / character data input from the key input unit 10. After the name data is retrieved through the memory unit 30, the flow advances to step S114.

In step S114, the controller 20 determines whether there is name data matching the input letters or numbers / letter data.

As a result of the determination in step S114, if there is name data matching the input letters or numbers / character data, the control unit 20 proceeds to step S116 and displays the name data according to the search result through the display unit 40. Display.

However, as a result of the determination in step S114, if there is no name data matching the input letters or numbers / character data, the control unit 20 proceeds to step S118 to match the search expression input by the user. Characters and sound sources indicating that data do not exist in the memory unit 30 are output. Such a character may be expressed, for example, as "no name found."

As described above, the present invention allows to enter letters and numbers in parallel with a toggle function of a soft key on a mobile communication terminal, and to search multiple search engines, for example, a phone number search engine, a name search engine, and a storage location search engine. It is integrated with a search engine and implemented to select and search storage locations and telephone numbers according to the input numerical data.

Therefore, the present invention can more easily perform a phone number search of the mobile communication terminal, there is an effect that can improve the ease of use for the user, and increase the sales to the terminal producer.
