When the middlelet is driven by the housekeeping machine, the middlelet converts the parameter value into the virtual machine. The virtual machine compares the hardcoded parameter value with the parameter value received from the middlelet, and returns a TRUE or FALSE value to the middlelet, and the middlelet is executed according to the returned value. Or installed.

In the prior art as described above, during execution or installation of the middlelet, the virtual machine receives a true or false value for the parameter value when receiving a new parameter or a parameter different from the hardcoded parameter value from the middlelet. ), The middlelet is not properly executed or installed on the mobile communication terminal. In addition, it does not provide a method for allowing a user to register and change parameter setting values set in the aforementioned virtual machine of the prior art.

Therefore, the above-described prior art has a problem in that when new parameter information is added to the middlelet MIDLet, it must be updated to a virtual machine having such new parameter information.

Accordingly, the present invention is to solve the above-mentioned problems in the prior art, the middlelet and the user when a new parameter is added to the Java program running in the mobile communication terminal, or has a setting value different from the hard-coded parameter value It is an object of the present invention to provide a Java program parameter setting method and a mobile communication terminal having the function of allowing a user to interact and register a new parameter or set a new parameter value.

In the above-described present invention, the Java program is produced as a middlelet (MIDLet), and the middlelet is provided in a JAVA (JAVA application descriptor) or JAR (JAVA archive) file format, and the parameter is a middlelet attribute parameter. It is done.

The virtual machine may be configured as one of a JAVA virtual machine (JVM) or a kilo virtual machine (KVM).

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram of a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 1, a mobile communication terminal 100 according to an embodiment of the present invention includes a control unit 110 for providing a voice and packet data service via a mobile communication system; A Java execution unit 120 for allowing a user to change a parameter setting by registering a parameter of the Java program or changing a parameter value, and including a virtual machine for executing the Java program according to the changed parameter setting value; A display unit 130 for outputting an execution state of a Java program in the Java execution unit 120; A key input unit 140 for receiving a user control command; An audio processor 150 for reproducing and encoding audio; A storage unit 150 for storing driving software and user input information of the mobile communication terminal; And an RF unit 160 for performing RF communication with the mobile communication system.

In the above-described configuration, the Java execution unit 120 includes: a WAP browser for providing a connection interface to a WAP server constructed in a wireless Internet network through a WAP gateway for providing a wireless Internet service; A JAAM application manager (JAM) for controlling the download of Java programs from the WAP server; A virtual machine such as a JVM (JAVA virtual machine) or a KVM (kilo virtual machine) for executing the downloaded Java program; It includes J2ME (JAVA 2 Mciro Edition), which provides programs for running Java programs. Here Java programs are usually written in the form of a middlelet (MIDLet) and provided in the form of JAD or JAR.

The user who wants to download the middlelet runs the above-described WAP browser to access the WAP server. After that, when the user selects the download of the MIDLet, JAM downloads the JAVA program according to the JAD or JAR file type, runs the virtual machine, and passes the downloaded Java program to the virtual machine. The virtual machine reads parameter information having middlelet attribute information mounted in the middlelet, interprets the parameter information, and performs setting for driving a Java program.

But. At this time, if the parameter included in the middlelet does not exist in the virtual machine, or if there is a parameter that is different from the parameter set value set in the virtual machine, the virtual machine may be newly registered by the user or the parameter of the middlelet. A user screen (interface screen) for inputting information for changing a value is output to the display unit 130. When the user inputs parameter information such as a parameter name, a parameter value, a range of parameter values, and the like, the parameter is stored to change the parameter setting value of the middlelet. Thereafter, the virtual machine installs or executes the middlelet according to the newly set parameter value, and outputs the installation or execution state of the middlelet to the display unit 130.

Table 1 shows the middlelet attribute as a parameter set to the above-mentioned middlelet.

Parameter name JAR JAD Setting value and meaning MIDlet-Name M M Middlelet name MIDlet-Version M M Middlelet version. The version value can be expressed as a.b.c (for example 1.2.3) MIDlet-Vendor M M Middlelet supplier name MIDlet- n M I Attribute describing the middlelet; the value contained in this attribute is described in text MicroEdition-Profile M I MIDP specification version in which the middlelet is driven MicroEdition-Configuration M I J2ME configuration information MIDlet-Description O O MIDlet description information MIDlet-Icon O O Middlelet icon MIDlet-Info-URL O O URL for additional information that the middlelet contains MIDlet-Data-Size O O Middlelet data size MIDlet-Jar-URL I M URL of the JAR file containing the attribute information of the middlelet MIDlet-Jar-Size I M Size of the middlelet JAR file in bytes MIDlet-Install-Notify I O URL of the MIDlet installation failure reporting location MIDlet-Delete-Confirm I O Display Information Before Deleting a Middlelet MIDlet-specific attributes O O Developer specific restriction information, such as the MIDlet execution time limit

2 is a flowchart illustrating a detailed process of a parameter setting method having attribute information of a middlelet among the mobile communication terminal 100 of FIG. 1 and the Java program setting method according to an embodiment of the present invention.

The detailed processing of the above-described method of setting the middlelet parameter will be described in detail with reference to the mobile communication terminal 100 of FIG. 1.

As shown in FIG. 2, when the user runs the WAP browser of the mobile communication terminal 100 to access the WAP server and selects the download of the desired middlelet, the JAM controls the download of the middlelet selected by the user. Download it (S10).

When the download of the middlelet is finished, JAM starts the virtual machine and passes the middlelet to the virtual machine. At this time, the virtual machine extracts the parameters included in the Java program and sets the conditions for the execution of the middlelet according to the set value. In this process, the virtual machine determines whether there is a parameter having a value different from the addition of a new parameter value or a preset hard-coded parameter value (S20).

As a result of the determination in S20, when there is a new parameter that is not parsed or a parameter having a value different from the preset parameter value is output, an information input screen of the corresponding parameter is output to the display 130 (S30).

The user inputs parameter information on the parameter information input screen output to the display unit 130 through the key input unit 140. The parameter information input at this time is shown in Table 1 above, and the set value is a parameter name, a type such as a string or a number, and a string comparison function (equal or not equal). Etc.), in the case of a number, has a number comparison function (>,> =, <, <=, equal, not equal, etc.), a set value, and the like (S40).

When the parameter information is input by the above-described process S40, the virtual machine changes and stores the setting of the parameter according to the input parameter information (S50).

Next, the virtual machine interprets the byte code of the middlelet and installs or executes the corresponding middlelet at the parameter value set by the process S50 (S60).

FIG. 3 is a flowchart illustrating an execution procedure of a middlelet after setting and storing parameter information by a user as an embodiment of process S60 of FIG. 2.

As shown in FIG. 3, after the parameter for the middlelet is set, the virtual machine receives parameter information from the middlelet MIDLet (S61).

After that, the virtual machine compares the parameter information input from the middlelet with the parameter values input by the process of FIG. 2, and determines whether the strings match, the number range matches, the screen output size, and the like according to the determination result. Alternatively, the middlelet is installed or executed by outputting a result value such as FALSE, and the installed or executed state of the middlelet is output to the display unit (S62).

The present invention described above allows the virtual machine to interact with the virtual machine by installing a setting information on a parameter value defining a new middlelet attribute when the middle machine is installed. This allows the user to change the settings of the middlelet or the hardcoded settings of the virtual machine. That is, in the present invention described above, when a question for installing or executing a middlelet is asked to a virtual user through a parameter included in the middlelet, the user answers the middlelet by inputting corresponding parameter setting information. Install or execute the middlelet according to the user's parameter setting information.

For example, if the parameter MIDlet-fullsize-support indicating the screen size is set to YES among the attribute values of the middlelet included in the middlelet, and the parameter is not specified in the existing virtual machine, the virtual machine may display the display unit ( After outputting the parameter setting screen named MIDlet-fullsize-support in 130), the user can select YES or NO so that the user can register and set the parameter MIDlet-fullsize-support. And if the user sets MIDlet-fullsize-support: no, the virtual machine reads the MIDlet-fullsize-support: YES parameter setting information from the middlelet and compares it with the information set by the user. When returned to the middlelet, the middlelet is installed or executed to not support fullscreen.

In another example, when the MIDlet-network-support parameter value is set to yes among the parameter values included in the middlelet, but the parameter is not specified in the existing virtual machine, the virtual machine is displayed on the display unit 130. Print the parameter -support and let the user select YES or NO to allow the user to register and set the parameter MIDlet-network-support. If the value registered by the user in the above-described process is MIDlet-network-support: no, the middlelet is installed by using the comparison value when the middlelet is installed or executed by the company providing the service by the middlelet. The middlelet executed in the mobile communication terminal may be set not to support a network service.

The present invention described above allows the user to register a new parameter or change the setting value when the middlelet has a new parameter that is not recognized by the virtual machine of the mobile communication terminal or has a setting value different from the preset value. This allows you to install a middlelet with new parameters without updating the virtual machine.

Therefore, the present invention described above solves the inconvenience of updating the virtual machine when a new version of the middlelet is provided in the prior art.
