The present invention relates to a content download system and a method thereof, and more particularly, to a content download system and a method in a WIPI terminal.

Current Internet technology has been developed to sufficiently reflect the needs of general users. In particular, the high speed of wired internet and the emergence of wireless internet are maximizing human information capability, and these technologies are already deeply penetrated into our society to be expressed as invisible industrial revolution.

The transition from analog society to digital society means revolutionary change, such as the quantum jump as discussed in quantum mechanics in physics. Even in the case of communication, the change from voice communication to data communication has a huge meaning such as quantum leap. In this situation, the implications of the emergence of data-centric wireless Internet can be very large. In short, it is the arrival of the personal mobile information age of dream that can exchange information anytime and anywhere smoothly. Of course, the development of related technologies is still more necessary than the user's demand for smooth two-way multimedia information exchange, but the emergence of the wireless Internet, which had not been imagined just a few years ago, and the structural change of the entire industry derived from it are very great. It must be work. From this point of view, wireless Internet is increasingly becoming an essential communication tool in our real life, and although it is not too long, its spread is enormous and is already entering the age of m-commerce.

On the other hand, if the technical classification of services based on the wireless platform can be largely divided into VM (Virtual Machine) technology and Native binary technology. These two technologies have mutually exclusive characteristics, so that the advantages of one technology are the disadvantages of the other, and the disadvantages of the other are the advantages of the other.

VM technology uses virtual machines to run programs. In other words, the written program is converted into intermediate code that can be operated in the virtual machine, and the virtual machine translates the corresponding code and converts the actual language into machine language for the CPU. This technology is already common through Java, and the Java VM is already being applied to the wireless Internet platform.

Another technology, native binary technology, generally follows the same process as how we write, compile, and run a program on a PC. In other words, the developed program is executed by creating a machine language that can operate on the CPU on which the program is executed.

VM-based wireless Internet platform has the burden of translating intermediate code into the execution process using a virtual machine, which is a major disadvantage in mobile phones with limited CPU performance and resources. However, VM technology has the advantage of providing system stability and complete security.

Unlike VM technology, the platform using native binary can utilize 100% of the performance of the onboard CPU, thus providing a very fast execution speed compared to the VM. However, the technology that uses native binary now has the disadvantage that it can harm the system stability by enabling malicious memory access by program developer.

Accordingly, the Wireless Internet Platform For Interoperability (WIPI) wireless Internet platform has been designed and developed as a platform with the advantages of these two distinct technologies. That is, it has the advantages of Java language and execution performance of Native binary. Therefore, the WIPI platform adopts C and Java as basic languages, and the application loaded on the mobile terminal is made of native binary to improve execution performance.

However, in the case of WIPI-Java based content, the performance of the mobile terminal was slow due to the nature of Java.

In addition, since the execution speed of the CPU mounted on the mobile terminal increases with the development of the mobile terminal technology, there is a need to differentiate it from the download method according to the conventional CPU speed.

An object of the present invention is to provide a system and a method for downloading a content in a WIPI terminal that can run WIPI-java-based content more quickly in a mobile terminal.

In addition, another object of the present invention is to provide a content download system and method in a WIPI terminal that varies the format of the download content according to the CPU type of the mobile terminal.

In order to achieve the above object, a content download system in a WIPI terminal according to the present invention, a content provider server for generating WIPI content (hereinafter referred to as CP server); A download server that receives content from the CP server and downloads the content to a mobile terminal through a mobile communication network; A user side mobile terminal which downloads and executes content from the download server; And a WAP server for providing a content menu page to the mobile terminal so that the mobile terminal user can select desired content.

In addition, the content download method in a WIPI terminal according to an aspect of the present invention, (a) a content registration server to register the WIPI content divided into WIPI-C and WIPI-Java from the CP server; (b) a download server receiving a request for downloading the WIPI content from the mobile terminal; (c) downloading, by the download server, the installation file for the WIPI content to the mobile terminal; (d) the download server performing content provisioning through terminal information transmitted from the mobile terminal; (e) downloading, by the download server, an executable file of the WIPI content to the mobile terminal; And (f) performing a charging after the download server receives an installation completion response from the mobile terminal through an HTTP header of a predetermined protocol.

In addition, the content download method in the WIPI terminal according to another aspect of the present invention, (a) a content registration server to register the WIPI content divided into WIPI-C and WIPI-Java from the CP server; (b) a download server receiving a request for downloading the WIPI content from the mobile terminal; (c) downloading, by the download server, the installation file for the WIPI content to the mobile terminal; (d) the download server performing content provisioning through terminal information transmitted from the mobile terminal; (e) converting, by the download server, the binary code content that can be transmitted to the mobile terminal through a COD server if the content requested by the mobile terminal is WIPI-Java content; (f) downloading, by the download server, an executable file of the WIPI content to the mobile terminal; And (g) performing a charging after the download server receives an installation completion response from the mobile terminal through an HTTP header of a predetermined protocol.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments. Like reference numerals refer to like or similar elements throughout the drawings.

1 is a block diagram showing a content download system in a WIPI terminal according to an embodiment of the present invention.

As shown in Fig. 1, the system includes a content provider server (hereinafter referred to as CP server) 300; A content registration server (DCMF, Digital Contents Management Framework) 600 that receives content from the CP server 300 and transmits meta information and physical files of the content to a download server to be described later; A download server (hereinafter referred to as a download server) 200 of a mobile communication system operator for downloading the registered contents to a mobile terminal through a mobile communication network; A COD (Compile On Demand) server 400 connected to the download server 200 to receive the contents of the WIPI-Java based bytecode and convert the contents into binary coded contents; A user side mobile terminal 100 which downloads and executes content from the download server 200; And a WAP server 500 for providing a content menu page to the mobile terminal 100 so that the mobile terminal 100 can select a desired content.

The download server 200 receives the WIPI-based content from the CP server 300, and when the content download request is received from the mobile terminal 100, analyzes the information of the mobile terminal 100. In addition, a file transmission method (eg, file compression) is determined and the content is downloaded to the mobile terminal 100 through the mobile communication network. In addition, when the content is WIPI-Java based content, the content converted into binary code is downloaded to the mobile terminal 100 through the COD server 400.

The COD server 400 receives the WIPI-Java based bytecode content (jar file), and generates a binary file executable file (extension is dlf) and a resource file (extension jar) except for the executable file. Thereafter, the executable file having the extension of dlf and the executable file related resource file having the jar extension are packaged and provided to the download server 200 in a file format for download having an extension of smf.

Hereinafter, a content download method in a WIPI terminal according to an embodiment of the present invention will be described.

First, the content registration server 600 receives the WIPI-C, WIPI-Java content from the CP server 300 (S201).

At this time, in the case of content that is WIPI-C, the CP server 300 registers a daf file, an icon, and an animation icon file, which are executable files, and provisions information (eg, GIGA information, platform version information, and mobile terminal color) of the content. Information, audio information, LCD size information), and information required to generate DD (Download Descriptor) are inputted. If there is a library, dlf related information is inputted, and then DRM or upgrade related option information is inputted.

On the other hand, in the case of WIPI-Java content, items necessary for provisioning (eg, GIGA information, platform version information, mobile terminal color information, audio information, and LCD size information) are registered, and information required for DD generation (eg, platform). Register name, version, DLF information and optional information related to upgrade.

Subsequently, when a download request is transmitted from the WIPI content from the mobile terminal 100, the download server 200 first downloads the DD file which is the installation information on the WIPI content (S202-S203).

At this time, the upgrade information and the DRM information for the content are recorded in the DD file. In addition, in the DD information, the proxy IP and port can be changed, and thus can be downloaded directly from an external download server (not shown) instead of the download server 200.

Subsequently, the download server 200 performs content provisioning through terminal information (transmitted in an HTTP body) transmitted from the mobile terminal 100 to check whether the content is suitable for the mobile terminal 100. (S204).

Thereafter, the download server 200 downloads the executable file of the content to the mobile terminal 100, and when the content is completed in the mobile terminal 100, through the HTTP header of the protocol determined from the mobile terminal 100 After the response is uploaded, billing is performed (S205-S206).

On the other hand, after step 204, the download server 200 converts the binary code content that can be transmitted to the mobile terminal 100 through the COD server 400, if the content requested by the mobile terminal 100 is WIPI-Java content Transmission to the mobile terminal 100.

That is, in the case of the WIPI-Java content, the execution speed of the mobile terminal 100 is slower than that of C, so that the byte code of the jar file registered by the CP server 300 is compiled through the COD server 400 so that the binary content of C can be obtained. Convert to Accordingly, the COD server 400 receives and compiles a jar file, which is a byte code of WIPI-Java contents, and, as a result of the compilation, a dlf file in which an executable file is converted into binary, and a jar file except an executable file. It is divided into two, which is packaged in a smf file (eg, Sktelecom coMpression Format of SKT's WIPI service standard) according to a predetermined standard and transmitted to the download server 200. Then, the download server 200 transmits the smf file of the content requested by the mobile terminal 100 to the mobile terminal 100. Then, step 206 and later are performed.

On the other hand, in step 204, the download server 200 performs a different download service according to the type of the mobile terminal 100 that requested the content.

That is, in the case of the general mobile terminal 100, the mobile phone number and the mobile terminal 100 information are acquired through a mobile identity number (MIN) included in the terminal information of the mobile terminal 100. However, in the case of the client ID for protecting the MIN information and the URI mobile terminal 100, the mobile terminal 100 obtains a phone number after the authentication process in step 204, and the mobile terminal 100. After acquiring the mobile terminal 100 information in association with the UAProfile according to the URI information included in the information, it is determined whether to provide an installation file.

On the other hand, after step 205, the following process may be added. In other words, as a result of the provisioning of step 204, the content requested by the mobile terminal 100 is downloaded by changing the file transfer form according to the CPU type of the mobile terminal 100. That is, when the CPU of the mobile terminal 100 is a terminal having excellent performance (for example, the ARM9 series), the smf file is compressed and downloaded to the mobile terminal 100, and then the steps 206 and below are performed.

While the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will recognize that various modifications or changes can be made without departing from the spirit and scope of the invention.

As described above, according to the present invention, in the case of WIPI-Java content, by packaging and downloading resource files, executable files, libraries, etc. registered by CP using a COD server, content execution speed in a mobile terminal can be improved. It can be effective.

In addition, according to the present invention, if the CPU of the mobile terminal more than a certain performance by transmitting the compressed executable file, there is an effect that can reduce the call charges and improve the download speed.
