Description

JAVA PROGRAM FREE RUNNING METHOD FOR MOBILE COMMUNICATION TERMINAL}

1 is a flow chart showing the operation of the embodiment of the present invention.

The present invention relates to a method of freely executing a Java program of a mobile communication terminal. In particular, when a Java program for a Java virtual machine embedded in a mobile communication terminal is downloaded, the mobile communication is executed freely for a predetermined number of times to confirm a user's purchase intention. It relates to a method of running a Java program free of the terminal.

Recently, according to the trend that the functions of mobile communication terminals are diversified, SMS messages, phone books, schedule management, calculators, phone books, in addition to voice call processing, which are the functions of mobile communication terminals, Additional functions such as games and internet browsing functions have been added and used.

These functions are determined and released from the production of the mobile terminal in advance, and because similar functions and different functions are distinguished and provided according to the model of the mobile terminal, overlapping investment and mobile communication according to the development of the same function by the mobile terminal manufacturer. It is not possible to satisfy different tastes according to the age group of users who use the terminal.

In addition, when a function is added to a mobile communication terminal, in order to use the added program, the user has to visit a contact service center to upgrade the program as well as all functions of the mobile communication terminal. Follows.

That is, due to the structure of the mobile communication terminal, data cable must be used to change the function, so that the external interface is not easy and generalized dynamic program environment such as DOS or Windows in PC is not provided. Therefore, the manufacturer of the mobile communication terminal develops all the software (S / W) and the user has no choice but to upgrade it directly at the service center.

In order to improve such a disadvantage, a platform for providing a dynamic environment for a mobile communication terminal such as GVM, JAVA, BREW, etc. has been developed.

The GVM is a mini-C, JAVA is a Java language, BREW is written in C language can be stored and used in the user's mobile terminal through the data service of the mobile terminal. There are applications currently being serviced such as games, location information, securities, karaoke, and e-books.

The platform that provides such a dynamic environment currently operates as one of the menus of the mobile communication terminal, and if a user wants to use a desired application program, the user selects the menu driving the platform providing the dynamic environment from the menu of the mobile communication terminal. Then, the user selects and uses the desired application program according to the method of managing the application program of the platform providing the driven dynamic environment.

Among the various platforms, the Java platform has the largest user base, and the recently released mobile communication terminal basically supports the Java platform.

Downloading and executing these Java programs are carried out through the following process.

First, a Java application link is selected from a server on a network using a browser of a mobile communication terminal, and a Java Application Manager file (Java Application Descriptor (JAD)) is executed from the server by running a Java Application Manager program (JAM). Download.

In addition, the contents of the Java application manager file are analyzed to determine the location of the Java program file and the Java data file existing on the network, and the Java program file and the Java data file are downloaded to the mobile communication terminal. Save to storage area.

The Java application manager program is used to drive a Java virtual machine for executing the Java program file and the Java data file, and transmit the charging information to the server.

As described above, when a Java application is downloaded in the related art, a browser (a browser having the same function as a swap browser or a web browser) embedded in a mobile communication terminal is used to find and download a location on the network of the corresponding application. At this time, the charging process for the corresponding application is executed based on the completion of the download or the execution of the download.

That is, the user does not know the operation of the corresponding application until the application is downloaded to the mobile communication terminal equipped with the Java virtual machine, so if the user is operating differently than expected as a result of executing the already charged application, the user May cause a complaint about the purchase of the application.

Therefore, even if you download and run an application with a huge name or information, even if you provide inadequate content that does not meet the user's expectations, the billing has already been completed, and because the user used the application, the refund is difficult, and the user's complaints will increase. There is no choice but to.

As described above, in the case of downloading an application that can be executed by the Java virtual machine embedded in the mobile communication terminal, since the charging is performed at the start or completion of the download, the operation of the application can be confirmed in advance. After the buyer does not know how to purchase the desired application to run, if you purchase an application that works differently than expected to waste the cost and time, there was a big inconvenience for the user.

In view of the above problems, the present invention allows a server providing a download of a Java application to specify a free usage count of the corresponding application in a Java application manager file, and when the user who downloads the application performs the free usage count, Do not process the billing, and only if the number of free use is exceeded, the user is asked whether to purchase or not to select the billing or application deletion, so that the user can check the contents of the application before purchase Its purpose is to provide a free way to run Java programs.

The present invention for achieving the above object comprises the steps of a terminal user accessing the server to download a Java program including information on the number of free execution; If the user is instructed to execute the Java program, executing the corresponding program while reducing the number of free executions, and when the free execution is completed, inquiring whether the user purchases the program; Providing billing information to the Java server when the user selects a purchase, cancels the restriction on execution, and restricts the execution of the application when the purchase is not selected; Generating related information upon deletion of the Java program, and based on this, characterized in that it comprises the step of preventing the duplicate download or free running of the same Java program that can be used for free.

The means built in the mobile communication terminal may include a browser for connecting to the server and downloading files, a Java virtual machine and a Java application manager program for managing and executing a Java program.

When described in detail with reference to the embodiments of the present invention as described above.

1 is a flowchart illustrating an operation according to an exemplary embodiment of the present invention, and may be divided into two cases as shown. That is, the method may be divided into a case of downloading a Java application using a means built in the mobile communication terminal and a process of executing the Java application.

In the following description, it should be noted that the present invention focuses on allowing a user to check a desired application and then purchase it by downloading a Java application and using it for a predetermined number of times for free.

In order to carry out the present invention, whether or not to execute the free execution of the Java application to be downloaded and the number of free executions must be specified on the Java server side. . In other words, when a user downloads an application, the information related to free execution is added to the Java application manager file (Java Application Descriptor (JAD)) which is downloaded first. Can be provided to the terminal. Although not shown in the flowchart shown, this is basically a task that must be performed on the Java server side.

Now, let's look at an example of how to download a real Java application, run it for free, and handle billing.

First, the user selects a desired application link by accessing a Java server on a communication network through a browser (a swap browser or an equivalent function browser) built in the mobile communication terminal. That is, a user downloads a Java application by accessing a web page for mobile communication terminal (WML, HDML) having a link to a Java application, and then selecting a desired Java application link by the user's designation. .

When the Java application link is selected, the Java application manager (JAM) embedded in the mobile communication terminal is driven to download and analyze the Java application manager file from the Java server. In this process, the Java application manager program of the mobile communication terminal analyzes the Java application manager file (descriptor) and checks information on the corresponding application, information on whether or not to run free of charge, and the number of free executions, so as to obtain free execution count information. Will be set.

In addition, after confirming a location on a communication network of an actual Java application included in the Java application manager file, and downloading a Java application (Java program and Java data) based on the content, the Java application manager file is stored in a preset Java application storage area in the mobile communication terminal. Save it.

If a free execution item included in the Java application manager file is not set, that is, an application that cannot be freely executed, the application is executed by executing a Java virtual machine, and charging information is provided to the Java server or the charging server. To be charged. In other words, the conventional method is used as it is.

However, if the application can be executed for free, run the Java virtual machine to execute the application, and reduce the preset number of free execution (managed by the Java application manager program).

If the reduced number of free execution is greater than zero, the application can be reused. If the number of free execution is zero, that is, if the number of free execution is executed, the user can display a screen asking whether to purchase the application. Allows you to decide whether to buy.

If the user selects a purchase, the purchase selection result and billing information are transmitted to the Java server or the billing server. If the purchase is not selected, the purchase selection result is transmitted to the Java server or the billing server, and the application (Java program, Java). Data, files generated through the application execution) are removed from the mobile communication terminal. Of course, you can also ask whether or not you want to purchase without restricting use.

If the user downloads the same application again to repeat the free use without choosing to purchase, the user may leave some information when the application is deleted or the Java application manager may recognize it to prevent free use again. The Java server itself can detect this and disable the free execution if it is downloaded repeatedly.

As described above, the method for freely executing the Java program of the mobile communication terminal of the present invention designates the number of free use times of the corresponding application in the Java application manager file on the server providing the download, and provides the download, and the user who downloads the application executes it. If the number of free usage is exceeded, the user may be asked whether or not to purchase the product, and the charge or deletion of the application may be performed. Therefore, the user may decide to purchase the application after executing the downloaded application free of charge before selecting the purchase. Therefore, it is possible to prevent unnecessary billing payments and allow users to experience various applications, thereby ultimately expanding the application market.
