For example, the mobile communication terminal has a user interface such as a standby screen, a phone book or an address book, a call list, etc., respectively, and is implemented as a Java application.

The memory 30 stores a plurality of data, and each application data required for driving the mobile communication terminal is stored. In addition, data transmitted and received through the communication module 40 is stored, and data generated during the operation of the mobile communication terminal are temporarily stored.

The application control unit 20 performs a management function of adding, deleting, modifying, and updating an application mounted on the mobile communication terminal. In this case, the application controller 20 manages the application by downloading upgrade data from the outside through the communication module 40 for the application mounted in the mobile communication terminal to repair or update a specific application.

In particular, the application control unit 20 enables selective updating of the respective Java modules among the plurality of applications of the user interface mounted in the mobile communication terminal.

In this case, the mobile communication terminal is provided with a protocol for transmitting multimedia and a browser for transmitting multimedia data for updating a Java application. For example, a WAP browser may be used.

The application control unit 20 downloads data for the application through the WAP browser when a guide message is received from the outside or a key is input according to a user selection. In addition, the application control unit 20 stores in the memory 20 information about an old version or a new version for the application to perform management functions such as maintenance, maintenance, and update for the application.

In addition, the application control unit 20 analyzes and installs the downloaded data, repairs or updates the application, and executes a specific application according to a control command of the control unit 10.

In particular, the application control unit 20 manages a Java application for each module of the user interface as described above.

Here, the platform structure of the application control unit 20 and the mobile communication terminal will be described in more detail as follows. 2 is a block diagram showing the structure of a mobile communication terminal according to the present invention.

As shown in FIG. 2, the mobile communication terminal includes hardware 110, an operating system 120 of the mobile communication terminal, a Java virtual machine (JVM) 140 that executes a Java application, and changes. And an application unit 150 capable of updating, adding, and deleting, a JAM (or AMS) 160 managing a Java application, and a native application 170 controlling call and data transmission and reception.

In this case, the Java virtual machine (JVM) 140 includes a connected limited device configuration (CLDC) 142 and a mobile information device profile MIDP (Mobile information device profile). In addition, the native application (170) includes a call manager (CM) and a data transmission and reception manager (RX, TX).

The application unit 150 includes a plurality of program modules for the user interface of the mobile communication terminal and program data according to additional functions of the mobile communication terminal.

In addition, the application unit 150 is configured to include an emergency agency module (151) for temporarily operating the mobile terminal when an application error occurs in the mobile communication terminal.

In this case, the emergency management module 151 provides a basic user interface screen and some basic functions or network functions according to the driving of the mobile communication terminal. For example, the emergency management module 151 performs a role such as a safe mode of a computer. ware) is preloaded and linked in advance, ie, ROMized.

Here, the application unit 150 includes an application program 152 according to the idle screen configuration, an application program 153 according to the call log list, a phone book application program 159 and the like. In this case, the plurality of application programs are Java applications.

In this case, the application unit 150 configures each application module independent of the middlelet suite (MIDlet suite), each descriptor file for each module JAD (JAva application descriptor), the class (Class) and the It consists of a Java application resource (JAR) composed of resources. In this case, the JAD file of each user interface module includes unique data called a MIDlet version.

When the Java virtual machine 140 receives data through the input unit 50 and a control command corresponding thereto is applied from the controller 10 to the application controller 20, a specific application is executed from the application controller 20. The control command in accordance with the authorization. It executes the application of the application unit 150.

The Java application manager (JAM or AMS) 160 downloads JAD and JAR files for the plurality of application modules of the application unit 150 through the communication module 40 using a WAP browser or the like. .

At this time, the Java application manager (JAM or AMS) 160 is an application management software for supporting a new application model of the CLDC / MIDP platform, and downloads, installs, upgrades, runs, and deletes MIDP applications, that is, MIDlets. .

In addition, the Java application manager (JAM or AMS, 160) manages the old and new versions of the application, at this time, it is managed based on the information of the JAD included in the MIDlet suit.

That is, the Java application manager (JAM) 160, as shown in Figure 3, the version for the module based on the unique attribute of the MIDlet version of the JAD file included in each application module of the application unit 150 Will be managed.

Here, when the Java application manager (JAM) 160 receives an upgrade guide message for a specific application of the mobile communication terminal from the outside through the communication module 40, the Java application manager (JAM) connects to the corresponding server using the browser. Upon receiving the upgrade data, the upgraded module installs and executes the upgraded new version of the application. In addition, the Java application manager (JAM) 160 upgrades a specific application through external access according to the upgrade request data input through the input unit 50.

Therefore, the mobile communication terminal is configured as a Java application implemented in Java as described above, so that the data can be updated by receiving data from the outside through the Java application manager, without upgrading the entire mobile terminal program Selective upgrades are available for each part, making it easy to maintain, manage, and update applications.

In addition, when the mobile communication terminal is later equipped with a CLDC HI (Host-pot implementation), it is easy to provide a multi-tasking (Multi tasking) function.

Looking at the operation of the present invention configured as described above are as follows. 4 is a flowchart illustrating a method of upgrading a mobile communication terminal according to the present invention.

When an upgrade guide message for a specific application is received from the outside (S1), the mobile communication terminal accesses the corresponding server using the URL information of the guide message. (S2)

In this case, the mobile communication terminal can access the application upgrade data of the mobile communication terminal through a predetermined authentication process.

The mobile communication terminal downloads a descriptor file (JAD) for the upgraded application, analyzes it, and compares the version information included in the descriptor file (JAD) with the version of the currently loaded application.

At this time, the mobile communication terminal checks the version through an attribute called MIDlet version of the descriptor file (JAD).

If the version of the upgrade data is newer than the version of the current application, the mobile terminal downloads the upgrade data. (S4, S5)

The mobile communication terminal installs and executes the downloaded upgrade data to perform the upgraded new version of the application. (S6, S7)
