3 is a flowchart illustrating a procedure of processing a Java middlelet protection function in a mobile terminal according to an embodiment of the present invention.

The present invention relates to a Java middlelet processing method of a mobile terminal, and more particularly to a method for processing a protection function of the Java middlelet.

Current portable terminals are equipped with various multimedia functions such as camera, satellite and terrestrial digital broadcasting (DMB, DVB) in addition to voice and data communication functions. The multimedia function mounted on the portable terminal may include a game. The mobile terminal may download a game through a wireless communication network, and in the case of downloading a game, the mobile terminal may download the game into a Java middlelet form.

The midlet is an application programming interface (API) for mobile phones and pagers for the Java 2 Platform, Micro Edition (J2ME). As a new function in the Java middlelet, a protection function is newly added. The protection function is a function for preventing the deletion of the middlelet whose value is active. That is, it is a function that can not be erased in the middle of the middlelet management.

1 is a flowchart illustrating a conventional procedure of downloading and deleting a middlelet in a portable terminal.

Referring to FIG. 1, when the portable terminal does not generate a command for installing or deleting a middlelet, the portable terminal processes a function of the portable terminal in step 131. In this case, when the Java middlelet is downloaded through OTA (Over the Air), the mobile terminal detects it in step 111, and in step 113 generates a related installation file for installing the Java middlelet, In step 115, the memory area is accessed for protection in the portable terminal, the memory area is added and managed for the newly added middlelet, and in step 117, the downloaded middlelet is installed to use the middlelet. In addition, when deleting the middlelet, when the middlelet deletion command is generated, the mobile terminal detects the detected middle terminal in step 121 and accesses a memory area allocated separately for protection of the selected middlelet in step 123. After the memory area for the deleted middlelet is reduced and managed in step 125, the middlelet-related installation file of the corresponding memory area is deleted in step 127.

As described above, in order to process the protection function of the Java middlelet in the conventional mobile terminal, it is necessary to allocate one memory area in the mobile terminal, and to size the memory area according to the number of how many games exist in the current terminal. In addition, you should be able to inspect which games have protection turned on and then change those values to suit your needs. That is, the area of the memory must be secured in proportion to the number of middlelets installed in the portable terminal, and the value of the memory must be controlled according to the setting value of the protection function.

However, the conventional Java middlelet protection function as described above should be managed after securing a specific memory area according to the number of middlelets to be installed. However, the above processing method has a problem in that the size of the memory area must be adjusted according to the number of middlelets installed in the portable terminal. If the above method is not used, the value of the memory must be allocated to some extent in consideration of the maximum number of middlelets that can be installed. In this case, a problem of causing memory waste occurs. That is, in order to reduce the waste of memory and to manage properly, the complexity of adjusting and managing the size of the memory reserved for the protection is caused whenever the number of middlelets is changed.

Accordingly, an object of the present invention is to provide a method for efficiently processing a protection function of a middlelet by inserting protection information when installing the middlelet in a mobile terminal.

Another object of the present invention is to provide a method for inserting protection information into a file added to a middlelet when a middlelet is installed in a mobile terminal and automatically deleting files generated when the middlelet is installed.

According to an embodiment of the present invention, a method of processing a middlelet protection function of a mobile terminal adds protection information to a specific file among files generated when installing a downloaded middlelet and protects the specific file. Managing the protection function of the installed middlelet by using information, and deleting the protection information of the middlelet by automatically deleting files of the installed middlelet when the middlelet deletion request is made.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. It should be noted that the same configurations of the drawings denote the same reference numerals as possible whenever possible.

The present invention efficiently handles memory management when installing and deleting a middlelet-related file in a mobile terminal. To this end, the portable terminal according to an embodiment of the present invention inserts protection information into a specific file among the files added to the middlelet when installing the downloaded middlelet, and automatically deletes files generated when the middlelet is installed. To help. That is, when each middlelet is installed, there are several files added together per middlelet, and one bit is added to a specific file among the added files to efficiently manage the protection function. In this case, the mobile terminal does not have to consider how many middlelets are installed separately. Also, when the middlelets are deleted, the protection values of the middlelets that are deleted are automatically deleted because the files generated when the middlelets are installed are automatically deleted. It is automatically removed so that you can efficiently manage your middlelets.

Here, the midlet refers to an application programmed using MIDP, and in order to serve a mobile terminal user, the middlelet is a JAR file downloaded and installed to the mobile terminal.

 The middlelet inherits and executes javax.microedtion.midlet.MIDlet. The mobile information device profile (MIDP) is a mobile information device profile, and refers to a J2MEAPI that defines a method for a wireless telephone and a two-way pager to interact with a software application. Applications written in compliance with this standard are called middlelets.

The portable terminal may be connected to a public wireless communication network (for example, CDMA, GSM, UMTS, etc.) through the wireless communication unit 220, and to a local area wireless communication network (for example, WAP, WiBro, etc.) through the local area communication unit 230. Can be connected. The WAP (Wireless Application Protocol) is a published specification that adds a large portion of the Web protocol or adds new functions so that a portable terminal can perform a wireless network usefully. Therefore, the mobile terminal can be connected to a web server through the WAP. Accordingly, the mobile terminal may download a middlelet created on a web server or the Internet through the local area communication unit 230 or the wireless communication unit 220.

To deploy and install the middlelet, you usually need jar and jad files. All class files and resources (image and audio, etc.) of the middlelet should be contained in one jar. In addition, in order to perform the function of installing, executing and removing the middlelets, the control unit 200 should be provided with the middlelet management software. The middlelet management software is called a Java Application Manager (JAM). The role of the JAM is to install, execute, and remove the middlelet, but the JAM may be configured and implemented differently according to a mobile terminal.

The Java middlelets vary in size. That is, when downloading the game by the middlelet, the size of the game may vary depending on the type. Therefore, in a situation where it is difficult to predict the number of middlelets that can be stored in the portable terminal, when a specific area of the data memory of the memory 210 is separately allocated to manage the protection, for the size and management of the memory 210 Several considerations can arise. Accordingly, in order to efficiently manage the memory 210, one file is selected from several files additionally generated when one middlelet is generated in the mobile terminal, and a protection bit is added to the selected file. can do. In this case, the memory does not need to be managed separately for the protection function of the middlelet, and the middlelet management can be efficiently performed.

According to an embodiment of the present invention, when processing the middlelet, by adding protection information to a specific file of the downloaded middlelet to protect the middlelet from being accidentally deleted, the files generated by the middlelet installation when deleting the middlelet It automatically deletes the protection value of the middlelet that is deleted.

Referring to FIG. 3, when a middlelet is downloaded through the wireless communication unit 220 or the short range communication unit 230, the controller 200 detects this in step 311 and stores the downloaded middlelet in the memory in step 313. Store in 210, and install the middlelet. In this case, the controller 200 sets protection information in a specific file among files generated when the middlelet is installed. In this case, the protection information may be configured with 1 bit, and the file to which the protection bit is added may be a specific location of a preset file. In step 315, the control unit 200 operates the installed middlelet.

If the user wants to delete the installed middlelet as described above, the user may request deletion of the installed specific middlelet through the key input unit 270. When the middlelet deletion request is generated, the control unit 200 detects this in step 321 and deletes the associated installation file of the corresponding middlelet in the memory 210 in step 323.

After downloading one Java middlelet as described above through a wireless communication network, setting protection information is added to a specific file among various files generated in the process of installing the downloaded middlelet, and protection in the specific file. Manage the values. When deleting a middlelet to which protection information is added to the specific file, the controller 200 automatically deletes the protection value of the middlelet which is deleted by automatically deleting files generated when the middlelet is installed.

As described above, the protection function of the middlelet according to the embodiment of the present invention can solve the trouble of memory management, and there is an advantage of not needing to store the protection information by allocating a predetermined size of the memory in the mobile terminal. That is, when each middlelet is installed in the mobile terminal, there are several files added per middlelet, and the protection function can be managed efficiently by adding protection information in a specific file among the added files. Therefore, it is possible to reduce the waste of memory and to simplify the management of the middlelet since it is not necessary to adjust the size of the memory held for the protection.
