Referring to FIG. 4, when list selection information using an application virtual list is received (S400), the communication terminal determines whether an application corresponding to the selected list is stored (S402).

That is, when a user of a communication terminal requests a search for an application using a menu, the communication terminal displays an application virtual list, and the user selects an application list that he wants to execute from the displayed virtual list. Then, the communication terminal determines whether an application corresponding to the selected list is stored.

If it is determined in step 402 that the application is stored, the communication terminal executes the application (S404).

If it is determined in step 402 that the application is not stored, the communication terminal establishes a session for using an application providing server and an online application and downloading an application, respectively (S406).

After performing step 406, the communication terminal downloads a user interface program for executing the corresponding application online through the set online application use session and at the same time downloads the corresponding application through the application downloading session (S408). .

When downloading of the user interface program is completed by performing step 408 (S410), the communication terminal uses the corresponding application function online using the user interface program (S412).

That is, after downloading of the user interface program is completed, when the user of the communication terminal inputs a user command using the user interface program, the communication terminal transmits the input user command to the application through the online application use session. The application providing server transmits a result of the user command to the communication terminal.

Even when the application is used online as described above, the communication terminal downloads the application through the application download session.

After the execution of the step 412, if the command to terminate the use of the application online is selected (S414), the communication terminal determines whether the download of the application is completed (S416). In this case, when the command to terminate the use of the application online is selected, the communication terminal releases the session for using the online application established with the application providing server.

If it is determined in step 416 that the downloading of the corresponding application is completed, the communication terminal releases a session for downloading an application set with the application providing server (S418). Then, the connection between the communication terminal and the application providing server is released.

If it is determined in step 416 that the download of the corresponding application is not completed, the communication terminal displays an application download termination query screen (S420).

The communication terminal user selects whether to end the download through the displayed application download end query screen.

When the application download termination command is selected by the user (S422), the communication terminal stores the download interruption information according to the download end time of the corresponding application (S424) and releases the session for downloading the application set with the application providing server (S424). S426).

The application download interruption information refers to the amount of packets downloaded for the corresponding application and may be stored in the communication terminal or the application providing server. When the application download stop information is stored in the application providing server, it is stored together with the communication terminal identification information.

If it is determined in step 422 that an application download continuation command is received, the communication terminal releases the session with the application providing server after completing the download of the corresponding application (S428).

5 is a flowchart illustrating an application management method of a communication terminal according to another embodiment of the present invention.

Referring to FIG. 5, when list selection information using an application virtual list is received (S500), the communication terminal determines whether an application corresponding to the selected list is stored (S502). The communication terminal determines whether an application ID corresponding to the selected list exists in the database.

As a result of the determination in step 502, if the corresponding application is stored, the communication terminal determines whether the download of the corresponding application is stopped (S504).

That is, if an application ID corresponding to the selected list exists in the database, the communication terminal determines whether the download of the corresponding application is stopped by using download stop information stored for the application ID.

In addition, if the corresponding application ID exists, the communication terminal may access the application providing server and determine whether to stop downloading of the corresponding application by using the download stopping information stored in the application providing server.

If it is determined in step 504 that the download of the application is not interrupted, the communication terminal executes the application (S506).

In this case, the communication terminal may access the application providing server and compare the versions of the corresponding applications before the application is executed, and if necessary, the communication terminal may download and execute the corresponding application from the application providing server.

If it is determined in step 504 that the download of the application is stopped, the communication terminal establishes a session for using the application and the online application and downloading the application, respectively (S508).

After performing step 508, the communication terminal downloads a user interface program for executing the application online through the set online application use session and at the same time the download of the application is interrupted through the application download session. It carries out from (S508).

After performing step 510, the communication terminal performs step 516.

If it is determined in step 502 that the corresponding application is not stored, the communication terminal performs step 534 from step 512.

Since step 512 to step 534 correspond to step 406 to step 428 illustrated in FIG. 4, a description thereof will be omitted.

6 is a flowchart illustrating a method of upgrading an application stored in a communication terminal according to the present invention.

Referring to FIG. 6, the communication terminal determines whether a predetermined application version checking cycle is performed (S600). The version checking period may be a period commonly applied to each application or the entire application.

If it is determined in step 600 that the version check period, the communication terminal checks the version of the application after accessing the application providing server (S602), it is determined whether the upgrade of the application is necessary (S604).

The method of determining whether the communication terminal needs to upgrade the application is as follows.

First, when the version check period comes, the communication terminal accesses an application providing server and transmits a version comparison request signal including the communication terminal identification information, the application ID and the version information to the application providing server. When the version providing request signal is received from the communication terminal, the application providing server extracts version information of the corresponding application and compares the version information of each application included in the version comparison request signal.

Then, the application providing server transmits version comparison result information including the application ID that needs to be upgraded to the communication terminal, and the communication terminal displays a version upgrade whether to include version comparison result information transmitted from the application providing server. Is displayed.

Second, when the version check period comes, the communication terminal accesses the application providing server and transmits a version information request signal including the communication terminal identification information and the application ID. Then, the application providing server extracts the version information corresponding to the application ID included in the version information request signal and transmits it to the communication terminal.

Then, the communication terminal compares the version information transmitted from the application providing server with the version information of the corresponding application to determine whether an upgrade is necessary.

By the above method, the communication terminal determines whether to upgrade the application.

If it is determined in step 604 that the version upgrade is not necessary, the communication terminal executes the corresponding application (S638).

If a version upgrade is necessary as a result of the determination of step 604, the communication terminal displays a version upgrade query screen (S606).

The version upgrade query screen includes application information that needs to be upgraded, and the user determines whether to upgrade the version through the version upgrade query screen.

When a version upgrade command is input through the displayed version upgrade query screen (S608), the communication terminal performs steps 610 to 632. Since steps 610 through 632 correspond to steps 406 through 428 of FIG. 4, a description thereof will be omitted.

If, as a result of the determination in step 600, the list selection information using the application virtual list is received by the user instead of the application version checking cycle (S634), the communication terminal determines whether an application corresponding to the selected list is stored. (S636).

If it is determined in step 636 that the application is stored, the communication terminal performs step 602.

If it is determined in step 636 that the corresponding application is not stored, the communication terminal performs step 610.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive.
