BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing content download in a mobile phone. More particularly, the present invention relates to a method and a download medium for splitting content in a mobile phone, which enables a mobile phone having a limited memory space to download a large amount of content provided by a mobile communication network. will be.

The download process refers to a series of processes for receiving content and installing the received content in an executable form on a wireless Internet platform.

With the development of mobile communication technology and wireless internet technology, mobile internet platform has begun to be installed in mobile phones.In order to facilitate the development of wireless internet service, we have standardized the wireless internet platform in Korea. Platform for Interoperability).

Most mobile phones on the market today come equipped with wireless Internet platforms such as WIPI. As the wireless internet platform is installed in the mobile phone, users can download and use various contents or Wi-Fi applications through the wireless internet network in addition to the additional services provided by the mobile phone by default.

A process of downloading content from a network in a conventional mobile phone will be briefly described.

First of all, 1). The mobile phone knows the size of the content (eg, an application) to be downloaded from the corresponding download server of the network. 2). The mobile phone pre-allocates a working memory (heap memory) corresponding to the content size. 3). Requests content transfer from the download server. 4). The content received from the download server is stored in the allocated operation memory. 5). When the download is completed, the contents are stored in the permanent memory while installing the contents stored in the working memory. 6). Run the saved content.

However, in the above-described conventional content download processing method, if the size of the content is larger than the size of the heap memory available in the mobile phone, the download cannot be processed, and if the content is compressed, the content size including the memory to be decompressed is included. It requires twice as much operating memory space, making it impossible to download large amounts of content, such as 3D games.

On the other hand, as the performance of mobile phones is getting very good, the contents (including applications) such as games with large capacities are increasing.In response to these trends, mobile phone manufacturers can use a motion memory (Heap) to download and process large contents. Memory capacity is being increased.

However, the price of the operating memory is quite expensive, and if the operating memory is increased every time the content capacity is increased, the unit price of the mobile phone increases and the product competitiveness becomes low.

Disclosure of Invention The present invention has been made in view of the conventional problem, and an object thereof is to provide a method for splitting a content download in a mobile phone, which enables download processing of a large amount of download content using a limited memory of a mobile phone.

According to an aspect of the present invention, there is provided a content download method in a mobile phone that downloads and installs content from a download server located in a network, the method comprising: informing a download server of a currently available heap memory size; A second step of allocating a download read buffer corresponding to a download size of the set session when the download server establishes a session and divides content in consideration of the available heap memory size; A third step of downloading divided content through the set session and monitoring occurrence of a download error; A fourth step of performing downloading after deleting the downloaded content if the download error occurs, and installing the downloaded divided content if the download error does not occur; A fifth step of checking whether there is remaining data to download from the download server; A sixth step of de-allocating the allocated download read buffer if there is remaining data to be downloaded, and repeating the first to fifth steps to download new divided contents; And a seventh step of releasing the allocated download read buffer and terminating the download if there is no remaining data to download.

The second step is characterized in that the download size of the established session is the same as the size of the available heap memory.

In the fourth step, when the download error occurs, the download content is restarted from the beginning after deleting both the currently downloaded divided content and the already downloaded and installed divided content, or the currently downloaded divided content is deleted, and the download error occurs. And downloading again for the divided content.

In the fourth step, when the split content is successfully downloaded, the downloaded split content is installed according to the additional installation operation if the split installation is already started, and according to the installation start operation if the split installation is not started. And installing the downloaded divided content.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

1 is a view showing the download environment and configuration in a typical mobile phone.

As shown in Fig. 1, the network environment to which the present invention is applied is the same as a typical mobile phone download environment. That is, the network environment is located in a network such as a mobile communication network or an internet network, and downloads the content selected by the user to the mobile phone 200 through wireless data communication, and connected to the download server 100 It includes a mobile phone 200 for requesting the download of a specific content and receiving and installing the corresponding content downloaded from the download server 100.

In addition to providing a general download service, the download server 100 performs a distributed transaction operation for content divisional download of the present invention at the request of the mobile phone 200. That is, the session for downloading the divided content (hereinafter referred to as "divided content") in order to download the divided content in consideration of the size of the available heap memory of the mobile phone 200 for the content divided download. Set to download the divided content to the mobile phone (200). Thus, the download content size of the session is equal to or smaller than the size of the available heap memory of the mobile phone.

Here, the mobile phone 200 may have a different usage space of the heap memory 200 according to the execution environment, that is, whether the application is executed and the size of the running application, as shown in FIG. 1. Therefore, since the execution environment of the mobile phone 200 is not the same every time the session is set, the download content size of the session is changed.

The mobile phone 200 collectively refers to all types of remote and short-range mobile communication terminals equipped with a wireless Internet platform (eg, Wi-Fi).

The mobile phone 200 is a downloader (210) for downloading and processing the content of the download server 100, a heap memory (RAM) 220 for storing the content received in the downloader 210, and the content is installed ROM 230 (or flash memory).

The ROM 230 stores an installation result of content stored in the heap memory 220.

2 is a flowchart illustrating a preprocessing process performed before performing a content division download method in a mobile phone according to the present invention. The preprocessing process shown in FIG. 2 is a process generally performed when downloading content to a mobile phone.

The user who wants to download the content is connected to the mobile phone 200 to the download server 100 (S210), after selecting the desired content from the content provided by the download server 100 (S220), corresponding to the download server 100 The download request for the content (S230).

Then, the downloader 210 determines the size of the content selected by the user (that is, the content to be downloaded) (S240) and compares the size of the heap memory with the size of the heap memory (S250).

In the comparison process (S250), if the size of the heap memory is larger than the size of the content, the downloader 210 allocates the heap memory as much as the content size as in the conventional process, that is, normal processing (S270).

On the other hand, in the comparison process (S250), if the size of the heap memory is smaller than the size of the content, the downloader 210 can not be processed by the conventional processing method, and performs the content split download processing method according to the present invention ( S280).

Hereinafter, referring to FIG. 3, a content splitting download method for a mobile phone according to an exemplary embodiment of the present invention will be described. 3 is a flowchart illustrating a method for splitting and downloading content for a mobile phone according to an embodiment of the present invention.

As shown in FIG. 3, when the downloader 210 determines the content divisional download process of the present invention, the downloader 210 requests the download server 100 to start downloading.

In this case, the downloader 210 and the download server 100 establish a session in consideration of the size of the download content corresponding to the size of the heap memory 220 available in the mobile phone 200 for the divided download of the content.

When the size of the divided content is determined according to the session setting, the downloader 200 calculates the size of the heap memory (that is, the size of the HTTP read buffer) that can store the divided content (S301), and calculates the HTTP as much as the calculated size. (hypertext transfer protocol) Read buffer 221 is allocated (S302).

When the downloader 210 allocates the HTTP read buffer 221, the downloader 210 performs an HTTP session to receive the divided content from the download server 100 through HTTP and stores it in the HTTP read buffer 221 (S303).

At this time, the downloader 210 monitors the occurrence of an error when downloading the content. If an error occurs before the divided contents are all stored in the HTTP read buffer 221 (S305), the contents stored up to this time and the divided contents ( In other words, the content stored in the HTTP read buffer is the content stored in the ROM in the divided installation) (S306).

Deleting both the content stored in the HTTP read buffer 221 and the content installed in the ROM 230 in response to an error in downloading the content is because the mobile phone 200 does not have a download inheritance function. The download download function refers to a function of downloading and storing and installing the broken part when the downloaded content is broken. If the mobile phone 200 is equipped with the download function, the downloader 210 deletes only the divided content in which a download error occurs when a download error occurs, and then downloads and deletes the deleted divided content again.

On the other hand, if the downloader 210 is divided content is successfully filled in the HTTP read buffer 221 (S304), after confirming whether the split installation has already started (S307), if the split installation is not started (S308), The install open API is called to install the content and install the divided content filled in the HTTP read buffer 221 (S309). On the other hand, when the split installation is started, the downloader 210 calls the Install Append API to perform additional installation on the split content filled in the HTTP read buffer 221 (S311).

When the downloader 210 installs the divided content stored in the HTTP read buffer 221 ROM 230, the downloader 210 gives an enable-temp attribute to the installed content to allow access to the installed content (S310). ).

When downloading and installation of one piece of content are completed in this way, the downloader 210 notifies the download server 100 of the currently available heap memory with the completion of the download process for the divided content, thereby downloading server 100. Tells you if there is any residual data to install.

If there is residual data to be installed, the downloader 210 releases the allocation of the HTTP read buffer 221 to download the new divided content (S314), establishes a session with the download server 100 again, and sets the session according to the session setup. The process returns to step S301 of allocating an HTTP read buffer corresponding to the size of the divided content to be downloaded.

On the other hand, if there is no remaining data to be installed, the download 210 calls the Install Commit API to perform the split content installation termination (S315), and additional work is required if additional installation work is required, such as registering a menu or saving an MSD for the downloaded content. After performing the operation, a disable-temp attribute is applied to the installed content to prevent access to the content (S316).

Then, the allocation of the currently allocated heap memory (that is, the HTTP read buffer) is deallocated and the download of the split content is completely terminated.

When the content is downloaded and the installation is completed, the mobile phone 200 executes the installed content so that the execution can be known on the screen.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

The present invention has the effect of allowing a large amount of content to be downloaded even in a mobile phone having a small operating memory (heap memory).
