Abstract

PURPOSE: A method for performing a user interface of a mobile communication terminal by using a WML(Wireless Markup Language) interpreter is provided to implement the user interface by using a WAP browser online and offline, thereby reducing burden of a UI task and easily upgrading a function. CONSTITUTION: When a terminal is booted, the terminal outputs a WAP page set to an initial screen to a WAP browser. If an optional event is generated while the initial screen is outputted, the terminal moves to other WAP page linked to the initial screen. The terminal interprets contents described in a WML on the corresponding WAP page, without moving the WAP page according to a kind of the event. The terminal outputs an interpreted result to a display device or a peripheral device such as an audio output device. The terminal describes portions of functions performed in each state on many WAP pages by the WML, and stores the functions, then moves to the corresponding pages by the event. The terminal interprets contents described on the pages, and performs a corresponding function.

Description

USER INTERFACE METHOD FOR MOBILE COMMUNICATION DEVICE USING WML INTERPRETER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user interface method of a mobile communication terminal using a wireless markup language translator (WML Interpreter). The present invention relates to a user interface method of a mobile communication terminal using a wireless markup language translator for implementing a user interface of a communication terminal.

WAP (Wireless Application Protocol) is a protocol implemented to be suitable for the Internet and mobile communication for application services operated through a mobile communication network.WML (Wireless Markup Language) is suitable for a mobile communication having low bandwidth and characteristics of a wireless terminal. Is used as the language.

WML is one of the markup languages based on eXtensible Markup Language (XML). It provides text-based content and considers limited user interface characteristics in wireless terminals such as mobile phones, personal digital assistants (PDAs), and two-way pagers. Made for

Unlike conventional browsers that use Hyper Text Markup Language (HTML) to display a variety of information on a computer screen, WML was developed for small devices such as wireless terminals.

For convenience of explanation, some terms used in the WAP will be defined first.

In the case of WAP, the content is sent to the client as WML and WML Script files rather than HTML. Here, WML and WML Script are the languages used to design and write WAP content.

WAP Browser is software that runs on a WAP device that translates WAP content from the Internet and determines how to display it on the screen of a WAP device (phone, PDA, etc.), which interprets WML as graphics or text. It includes a kind of WML interpreter that converts and outputs to an output device (LCD Screen, Speaker, etc.).

The WAP server is a wireless Internet host that contains wireless Internet contents produced in WML (Wireless Markup Language) for providing wireless Internet services based on the WAP protocol.

The operation of WAP differs only in that a WAP gateway exists between the WAP browser of the Internet and the wireless Internet.

In other words, the WAP gateway plays a role of converting between the WAP protocol and the HTTP protocol between the Internet and a wireless portable device such as a PDA or a mobile phone with a WAP browser.

Conventionally, when an event such as a key input occurs in a mobile communication terminal, a user interface task (hereinafter, referred to as a UI task) processes the event in the current state (displaying a screen or outputs an alarm sound), or When processing is difficult in a state, the event is processed by transitioning to another state.

In other words, all UI-related events are handled within the context of the UI Task.

1 is an exemplary diagram for explaining a state and a transition relationship therebetween in a conventional UI task.

As shown here, 'A state' corresponds to an idle state of the wireless portable terminal, and this state and the state transitioned therefrom may stay in the state, and a condition is met or a specific event is If it does, it can transition to another state.

At this time, each state has a function corresponding to the state in order to perform a corresponding function, which calls an UI related utility function to process an event that the UI should perform.

However, in the above method, when a menu list is changed during the development of an individual mobile communication terminal, the states are adjusted and thus the transition relationship is changed, and the addition of a new function or deletion of an existing function is followed. However, due to the characteristics of the terminal implementation, the UI task is overloaded, or the problem occurs in the priority setting of the event processing. .

Accordingly, the present invention was created to solve the above-mentioned conventional problems, and implements the user interface of the mobile communication terminal using the WML Interpreter of the WAP browser not only in the on-line state but also in the off-line state. It is an object of the present invention to provide a user interface method of a mobile communication terminal using a wireless markup language translator.

According to an aspect of the present invention, a mobile communication terminal having a built-in WAP browser for wireless communication includes outputting a WAP page (WAP page 1) set as an initial screen when the terminal boots up to a WAP browser. Step 1; A second step of moving to another WAP page (WAP page N) linked to the initial screen when any event occurs while the initial screen is output; And a third step of interpreting the contents described in the WML language in the corresponding WAP page without outputting the WAP page according to the type of the event and outputting the result to a peripheral device such as a display device or an audio output device. It is done.

1 is an exemplary diagram for explaining a state and a transition relationship between them in a conventional UI Task.

2 is an exemplary view for explaining a user interface method of a mobile communication terminal using a WML translator according to the present invention.

The present invention processes a screen display function according to a state cloth or each state that has been processed using a function in a conventional 'UI task' by using a WAP browser used for wireless data communication, thereby allowing an event in each state of a mobile communication terminal. Is generated, the WAP page written in WML displays each scene on the screen of the terminal and processes an event.

In other words, conventionally, when an event is detected, the process of calling the corresponding function, calling the screen control function again to output the result, or transitioning to the state for performing such processing is the context of the UI task. In the present invention, some of the functions are performed by a WAP page written using WML, thereby reducing the load of the 'UI Task'.

2 is an exemplary view for explaining a user interface method of a mobile communication terminal using a WML translator according to the present invention.

In the present invention, 'UI Task' is basically provided, and performs overall tasks for terminal management required for the terminal to operate, such as key input or event occurrence detection.

However, some of the functions previously performed by the 'UI Task', such as the state transition process caused by the occurrence of the event, can be processed in the page itself by the WAP page format, thereby reducing the load of the 'UI Task' It is.

As described above, the WAP page is written in the WML language, and the content and grammar are interpreted by the WML interpreter and output through the WAP browser.

The grammar format for composing WAP pages using the WML language may also include formats for graphics, images, and sound control. When the supported format is upgraded, more functions are also described in the WML language. It is self-explanatory.

When the terminal is booted as described above, the 'UI Task' is activated, and the WAP browser is driven in an off-line state without wireless data communication.

Accordingly, the WAP browser reads the initial screen (WAP page 1) corresponding to the idle state of the terminal from the memory, interprets it using a WML translator, and accordingly, the display device (LCD) and the audio output device (Speaker) of the terminal. ), Data (or signal) is output to the warning device (LED) and the like, to provide information to the user.

For example, when the terminal is booted, it displays the initial screen, outputs a warning sound indicating the completion of booting, describes the blinking LED on the WAP page using the WML language, and translates the WML interpreter into WAP. To perform these operations via a browser.

When a certain event (UI event A) occurs in the booting state through the above process, the 'UI Task' delivers it to the WAP browser, and the WAP browser is defined on the initial screen (WAP page 1). Accordingly, the user processes the 'UI event A' within the page or moves to WAP page 2 or 3 according to the link described in the page.

For example, if the initial screen (WAP page 1) is a screen displaying the date and time, and the linked page is the menu output screen (WAP page 2) when a flip or folder opening event (UI event A) occurs, the corresponding screen is displayed. When an event occurs, it moves to the page linked to it.

In this case, the movement from the current page to the linked page may be automatically moved to the corresponding page after a predetermined time, depending on whether the movement occurs when a certain event occurs. It can be done.

Therefore, in the above case, the flip or folder is opened and closed when an event occurs, and when the event occurs, it is linked to move to the corresponding page.

In this case, the WAP pages corresponding to each case are stored in the internal memory of the terminal, and the WAP browser reads each page from the memory, interprets the page through a WML translator, and uses the peripheral device to interpret the result. To provide.

On the other hand, in the on-line state, the WAP page downloaded from the content providers on the network is provided to the user through a peripheral device, and is off-line as in the case of the WAP browser. Return to the previously saved WAP page.

As described above, the user interface method of the mobile communication terminal using the wireless markup language translator of the present invention implements a user interface using a WAP browser both on-line and off-line, thereby reducing the burden of UI tasks and later. This has the effect of facilitating feature upgrades.
