In addition to the above, it is also possible to mount a mobile phone OS to be used in the next-generation mobile phone IMT2000.

Based on the operating base environment construction apparatus of the mobile phone terminal as described above, a wireless download method of a browser and application programs is as follows.

First, according to the present invention, the entire program to be downloaded is changed into several small execution modules. When an updater is needed, each module can be updated. At this time, the types of modules to be rewritten are as follows.

1) card: A card is a minimum execution unit of software for a mobile phone terminal in which an operating infrastructure environment building device of the mobile phone terminal is installed, and becomes a wireless upgrade unit. As shown in FIG. 2, the structure includes function position information for each function and respective function code texts corresponding thereto.

2) Package: A package is composed of variables and functions commonly referred to by several cards. This is to minimize the size of an executable file. The structure is shown in FIG. It consists of a function pointer carrying information, a global variable data area, and a global variable code text stored at a location indicated by the function pointer.

Using the card and package concept as described above, the present invention firstly divides the software for a mobile phone terminal into a card which is the minimum unit for each function described above. Secondly, the functions and variables that are common to each card are bundled together into a unit called a package. Third, determine the version and execution of carcards and packages. Lastly, the virtual machine code is generated using the separated source program as described above using the compiler for the operating-based environment construction device for the mobile phone terminal.

The software for each mobile phone terminal generated as described above is provided in a server on a wireless network and downloaded for each terminal.

The download process will be described with reference to the flowchart shown in FIG.

As shown, the download operation is performed on the mobile phone terminal side (FIG. 4A) and on the server side having software reconfigured based on the operating base environment construction apparatus for the mobile phone terminal as described above (FIG. 4). (B)).

First, the mobile phone terminal side and the server side respectively perform a predetermined program to start the operation (s401, s410).

The mobile phone terminal attempts to access a server of a wireless network by executing an internal application program, and when connected to the server (s402), requests a version information of an application program or a mobile browser from the server (s403).

Then, the server side executes a predetermined application program and checks whether there is a version information request from the connected mobile phone terminal (s411).

As a result of the check, if there is a version information request from the mobile phone terminal, the provided application program storage database is searched, and the version of the requested application program or mobile browser is read and transmitted to the corresponding mobile phone terminal (s412).

After requesting the version information from the server, the mobile phone terminal checks whether the data containing the version information is received from the server (s404), and if the version information is received, the received version is the version of the software currently installed on the mobile phone terminal. Compare with (s405).

As a result of the comparison, if the version information matches, execution of the corresponding application program continues (s401). If the version information does not match, on the contrary, the application program is determined to be upgraded and a new module is requested to the server (s406). ).

On the other hand, the server side checks the version information request from each mobile phone terminal, transmits the version information, and then checks whether there is a new module request from the mobile phone terminal (s413). Here, since a new module request from the mobile phone terminal is generated after the comparison of the version information, it is checked only after a predetermined time (the time required for the comparison and module request in the mobile phone terminal) has passed after transmitting the version information. If there is no new module request until the set time elapses, it is determined that there is no new module request and the connection and request processing of another mobile phone terminal are performed.

When the new module request is received from the mobile phone terminal, the internal program database is searched and only the upgraded module of the corresponding software is transmitted to the mobile phone terminal (s414).

In response to the request from the server for a new module, the mobile phone terminal receives the data transmitted from the server and stores the received new module (S408).

At this time, the storage of the transmitted data to the internal memory is made by the file interface module 210 of the operating layer 200, and receives only the upgraded portion, and stores the received data in an appropriate location.

If there are no more modules to receive (s409). End the program and reboot the terminal to run the upgraded program.

As described above, the present invention has the effect of increasing the portability of the hardware and shortening the development period of the program by minimizing the portion adjacent to the hardware by implementing the virtual machine technique in the smart phone, and in addition, In addition, it is possible to use an application program without accessing a server in a mobile phone terminal, and by upgrading only a part of the changed wirelessly, reducing communication time, and consequently, has an excellent effect of activating mobile data communication.
