Abstract

A character input method using a mobile standard platform in a mobile terminal is provided to enhance user convenience and practicability by changing an input method within a mobile terminal without having to connect the mobile terminal to an external PC. When the user inputs a particular key of a keypad to operate his mobile terminal, an application detects the key input(S301). A WMS(WIPI(Wireless Internet Platform) Messaging Solution) API(Application Program Interface) is called to transfer the key input signal to a terminal basic software of the terminal via a mobile standard platform(S302). The terminal basic software checks the received key input signal to check a pressed key, and transfers the check result to the mobile standard platform(S303). The mobile standard platform transfers the check result to the application via the called WMS API(S304). The application searches a key mapping table to check a pre-set key value corresponding to the pressed key(S305). The checked key value is outputted as a key value of the input key(S306).

The present invention relates to a mobile communication terminal, and in particular, a character input using a mobile standard platform of a mobile communication terminal that allows a user to easily and simply change the input method of the mobile communication terminal at any time without changing the basic software implemented by the terminal manufacturer. It is about a method.

A mobile communication terminal is a terminal that transmits and receives voice signals and data through a mobile communication system and provides a voice call service and a wireless Internet service to a user. The mobile communication terminal is implemented in a small size to facilitate portability. It is going on.

As described above, since the mobile communication terminal can be miniaturized, there is a limitation in the number and size of input keys of the input unit. Therefore, various input methods have been proposed to allow input of not only numbers from 0 to 9 but also characters such as English, Korean, Japanese, and Chinese using limited input keys.

For example, the input methods adopted and used as the Hangul input method in the current mobile communication terminal include the Cheonjiin method and the EZ Hangul method. The Cheonjiin method is a method of reducing the number of buttons required for Hangul input by allowing all vowels of Hangul to be completed by a combination of Cheon (·) and Ji (ㅡ) (ㅣ). This method is to set up and vowel and to change the consonant and vowel input according to the number of consecutive input of each button. In addition, various input methods have been proposed and used.

However, the above technology transfers an automata table configuration file (a table for managing consonant and vowel information set for each location set according to an input method) embedded in a wireless communication terminal to a PC via USB, and then sends After changing the automata table setting file through a software that can be changed, it is transmitted to the corresponding wireless communication terminal and set again, and it is inconvenient to use because it is not made in the terminal itself and must be processed in a separate PC. Since the method is set in the terminal basic software provided by the terminal manufacturer, the above method has a problem of changing the terminal basic software provided by the terminal manufacturer by transmitting the changed file back to the terminal.

An object of the present invention for solving the above problems is to provide a mobile standard platform of a mobile communication terminal that allows a user to easily and simply change the input method of the mobile communication terminal at any time without changing the basic software implemented by the terminal manufacturer. It is to provide a character input method.

Mobile standard API 14 represents an API for accessing the mobile standard platform 13. The mobile standard API 14 basically supports the functions of the terminal basic software 11, for example, a messaging API for supporting a messaging service capable of creating and sending a message such as SMS or MMS. Also known as the WIPI Messaging Solution) API.

The application program 15 is mounted to perform a predetermined function or service in the mobile communication terminal, and may be implemented by a mobile communication provider or implemented by a third-party content developer.

In FIG. 1, the application program 15 is implemented based on a mobile standard platform standard, and calls a specific function of the mobile standard platform 13 through the mobile standard API 14 so that the terminal basic software of the mobile communication terminal ( 11).

As a representative application program 15 mounted on a recent mobile communication terminal, there is a desktop service application that is executed on a desktop (also called a standby screen) of a terminal to perform a specified service. For example, there is a pop-up application such as a stock application that downloads and displays real-time stock information, and a content playback application that plays content of a specific format.

When the desktop service application is set on the desktop, the desktop service application remains driven until the setting release command is indicated. When the desktop service application is driven, a key input of the mobile communication terminal is generally performed by the desktop service application. Is first inputted, and communicates with the terminal basic software 11 through the mobile standard platform to confirm the corresponding key value, and then processes the function according to the confirmed key value.
