In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a configuration diagram schematically showing a configuration of a status display apparatus using a Java icon according to an embodiment of the present invention.

The state display apparatus 100 according to the present invention has a configuration including a key input unit 110, a control unit 120, a display unit 130, and a virtual machine execution unit 140.

The key input unit 110 is used to select an arbitrary menu from among a plurality of menus displayed on the display unit 130. In addition, the key input unit 110 transmits a command such as adding or deleting a menu by the user's key input to the controller 120.

When the controller 120 displays the Java task menu of the Java middlelet on the display unit 130 by executing the multiple virtual machine (MVM), the controller 120 controls the state of each middlelet to be displayed together in the middlelet list.

The display unit 130 also displays and outputs the state of each middlelet when displaying the list of Java middlelets.

The virtual machine execution unit 140 operates together with the execution of the Windows API according to the operation of the operating system (OS) when the device is powered on to execute a multiple virtual machine. This multiple virtual machine is a Java virtual machine and displays a plurality of menus on the display unit 130 as Java icons.

In addition, the virtual machine execution unit 140 may execute multiple virtual machines under the control of the control unit 120 according to a key input related to the user's “view menu”. The multiple virtual machines load predetermined libraries, call predetermined functions, and generate various tasks. Here, the virtual machine execution unit 140 includes a plurality of classes, including a middlelet (MIDlet) class required to execute multiple virtual machines. It also includes the J2ME CLDC / MIDP package.

2 is a diagram illustrating a life cycle of a middlelet during operation of a virtual machine execution unit.

All middlelets must inherit from the MIDlet class, and unless the inherited class is an abstract class, they must implement the abstract methods startApp, pauseApp, and destroyApp.

The life cycle of the middlelet shown in FIG. 2 is in the Paused state by the stop function PauseApp () once the middlelet is started by the function New () which starts a new middlelet. .

The middlelet is then activated by the start function StartApp () to become active.

Then, when the operation of the middlelet is terminated by the termination function DestroyApp (), the middlelet is terminated. Of course, the middlelet may be destroyed by the termination function DestroyApp () in the paused state.

3 is a flowchart illustrating a state display method using a Java icon according to an embodiment of the present invention.

Most of the real-time operating systems (Operating Systems) mounted on mobile terminals use Rex (REX), which is Qualcomm's operating system.

First, when the device is powered on, the control unit 120 operates the Windows API according to the operation of the operating system, and transmits a menu display command for executing the multiple virtual machines to the virtual machine execution unit 140 ( S302).

Here, the menu display command may be input to the controller 120 as the user performs a key input related to the menu display through the key input unit 110 to select an arbitrary menu.

According to the menu display command, the virtual machine execution unit 140 loads the wireless toolkit file 'WTK dll' to start the Java virtual machine, and calls the wireless toolkit start function 'WTK_Start ()' from the main thread. do. Here, the 'WTK_Start ()' function initializes the environment for REX, and creates and initializes a plurality of tasks. At this time, the task can be additionally created as needed, and the Windows API is used during the task creation process.

Subsequently, the virtual machine execution unit 140 checks the middlelets that are activated after the Java virtual machine is operated (S304). That is, the virtual machine executing unit 140 checks which middlelet start function StartAPP () of the start function StartAPP () for activating the middlelet is being used while the multiple virtual machines are executed.

The virtual machine execution unit 140 displays a plurality of menus according to the middlelet to the display unit 130 when there is a middlelet in which the start function StartAPP () is used among the plurality of middlelets. Among the plurality of menu lists, the list of activated middlelets is displayed separately (S308).

That is, the virtual machine execution unit 140 displays a plurality of task menus as a list as shown in FIG. 4, and separately displays each state of the middlelet on the right side of the menu bar. For example, if a middlelet among a plurality of Java task menus is running but is suspended (410, 440), and if the middlelet is running and operating but is a background (420, 430), the middlelet is If it is running and running, but in the foreground (Foreground), and so on.

Here, when the middlelet is being executed but held (410, 440), it corresponds to the Paused state in the life cycle of the middlelet of FIG. 2, and "3. Pause" in the case of the status display menu (Status). Corresponds to 470.

Also, if the middlelet is running and operating but is in the background (420, 430), it corresponds to the active state in the lifestyle of the middlelet of FIG. 2, and in the case of the status display menu, "2.Run" Corresponds to 460.

If the middlelet is executed and operated but is in the foreground, it corresponds to an active state in the lifestyle of the middlelet of FIG. 2, and "1.Active" in the status display menu (Status). Corresponds to (450).

The list of the plurality of task menus including the task status shown in FIG. 4 includes a "Texas Hol'dem" menu, a "Tetris" menu, a "Golden Warrier 2" menu, a "Bricks" menu, and a status display menu ( It includes a Status, an OK menu, a List menu, and so on. Here, the status display menu shows "1. Active" 450, "2. Run" 460, "3. Pause" 470, and "4. Delete" 480.

Thus, in the list of multiple Java task menus, through the task states displayed in each menu bar, the "Texas Hol'dem" and "Bricks" menus indicate that the middlelet is running but held (410, 440). Able to know. In addition, it can be seen that the "Tetris" menu and the "Golden Warrier 2" menu are states 420 and 430 that are in the background while the middlelet is running.

In this case, the user may check a plurality of Java task menu lists through the key input unit 110, select an arbitrary task menu from the list of Java task menus, and stop the running task menu. In addition, any task menu can be selected and deleted from the list of Java task menus. In addition, the menu of the inactive state from the list of the Java task menu can be switched to the active state by key input.

As described above, according to the present invention, when executing a virtual machine (MVM) in a mobile terminal to display a Java middlelet to the user, by displaying the state of each middlelet in the middlelet list, the middlelet to the user It is possible to realize a status display method and apparatus using a Java icon to let the user know whether this is being performed.
