KR20020095756A - Memory management method for mobile communication device - Google Patents

Abstract

PURPOSE: A method of managing a memory of a mobile communication terminal is provided to convert graphic contents stored in a temporary Internet file into a file format having an excellent compression rate, to store the converted graphic contents, and to convert into an original file format when re-accessing the same web page, thereby increasing using efficiency of the memory. CONSTITUTION: When a user accesses a web page by a web client(2), a web server(1) transmits various contents including a graphic image to the web client(2). The web client(2) displays the graphic image, and converts the graphic image into a file format having a high compression rate. The web client(2) stores the format-converted graphic image in a local memory. When the web client(2) re-accesses the same web page, the memory directly loads the same graphic image without downloading the graphic image. The web client(2) converts into an original file format before converting the file format of the loaded graphic image, and displays the graphic image.

Description

MEMORY MANAGEMENT METHOD FOR MOBILE COMMUNICATION DEVICE}

The present invention relates to a memory management method of a mobile communication terminal, and more particularly, to a memory management method of a mobile communication terminal to make the most of the limited memory capacity of the terminal when receiving a graphic-based web service using the mobile communication terminal. .

Most of the recent mobile communication terminals are capable of wireless Internet, and the next generation mobile communication terminals are also capable of video services.

On the other hand, in the case of accessing a web page using a PC (PC) in the past, the graphics-related contents of the previously accessed web page is temporarily stored in the local memory of the PC, and the next time to access the same web page By loading the temporary stored file without having to download the same graphic contents again, the graphic loading speed is increased.

Therefore, recently, even when accessing a web page using a mobile communication terminal, the web page access time is shortened by using the same method as described above.

However, as described above, the method of storing the graphic contents in the local memory to shorten the web page access time inevitably requires a large memory capacity.

Therefore, when using a hard disk as a storage device, such as PC is not a big problem, if there is a large storage device such as a mobile communication terminal there is a problem that the use of the storage memory of the terminal is limited.

That is, the method for storing graphic content related to web page display applied to a PC having sufficient memory capacity is limited to the amount of graphic content that can be stored when applied to a terminal that does not have sufficient memory capacity. Since the graphic content that consumes a lot of bandwidth must be newly downloaded, this causes a problem of slowing down the display speed of the web page.

Therefore, the present invention was created to solve the above-mentioned conventional problems. When accessing a web page using a mobile communication terminal, the graphic content stored as a temporary Internet file is converted into a file format having a high compression rate and stored. It is an object of the present invention to provide a memory management method of a mobile communication terminal that can improve the web page access speed while increasing the memory usage efficiency by converting and displaying the same web page in the original file format.

1 is an exemplary view illustrating a process of downloading a graphic image and converting and storing a file format when accessing a web page using a terminal according to the present invention.

FIG. 2 is an exemplary view illustrating a process of loading and displaying a graphic image stored in a memory when reconnecting to a web page accessed in FIG.

In order to achieve the above object, the present invention provides a method comprising: a first step of receiving various contents including a graphic image having a low compression rate of a web page when a user accesses a web page using a mobile communication terminal; A second step of displaying the received graphic image and converting the file into a file format having a high compression ratio; And a third step of storing the converted format graphic image in a local memory of the terminal.

According to the present invention made up of the above-described technical process, the first step of re-connecting to a web page that has already been accessed through the terminal, the same graphic image that was downloaded during the first connection directly without loading the image without downloading the image; And converting the file format of the loaded graphic image into an original file format before format conversion and displaying the converted file format.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

In general, the graphic content of a web page is in the form of GIF, BMP, and JPG files.

The most common file type is GIF, which is lower than JPG in terms of compression rate.

Therefore, in the present invention, when the downloaded graphic content in the form of GIF or BMP file is converted into a JPG file having a high compression rate and stored, and reconnected to a web page containing the graphic content, the original GIF or It is to restore and display in BMP file format.

This will be described in more detail with reference to the exemplary diagram of FIG. 1 as follows.

Once a user accesses a desired web page using a mobile client (Web Client) 2, the web server 1 which operates the web page has various contents including graphic images (File1.gif, File2.gif). Is transmitted to the terminal 2 via the wireless network.

Then, the terminal 2 displays the graphic images (File1.gif, File2.gif) as they are, and converts them into a JPG file format having excellent compression ratio by a graphic conversion algorithm and stores them in the memory.

That is, in the case of storing the graphic image in the GIF file format as in the prior art, if five images can be stored, the present invention can store more images in a memory having a storage capacity.

Of course, this time further includes information for restoring the JPG file format back to the GIF file format.

Next, FIG. 2 is an exemplary view illustrating a process of loading and displaying a graphic image stored in a memory when reconnecting to a web page accessed in FIG.

As shown in the figure, when the user reconnects to the web page connected in FIG. 1 using the web client 2, the web server 1 operating the web page is a graphic image (File1.gif). , File2.gif) is transmitted to the terminal 2 via a wireless network.

In this case, when the same graphic image to be transmitted from the web server is stored in its memory, the terminal 2 directly loads the image from the memory without downloading the image and displays the same.

However, since the original file format (GIF) and the file format (JPG) stored in the memory are different, the JPG file format is converted into the original file format and displayed by the graphic conversion algorithm.

At this time, by properly using the restoration information stored during the format conversion, it is possible to restore and display the same color and texture as the original file format.

In other words, by applying the present invention to the mobile communication terminal, the memory usage efficiency is increased, the web page access speed is improved, and the color and texture of the graphic content are not changed at all.

In other words, the technique according to the present invention uses the storage memory more efficiently than when it is not used. As a result, the already stored content does not need to be downloaded again, thereby reducing the bandwidth of the channel and also providing a web page. Can also increase the display speed.

In the above embodiment, the JPG and GIF file formats have been described as an example, but it will be apparent that the effect of the present invention may be further increased when another file format having excellent compression ratio is applied instead.

As described above, in the memory management method of the present invention, when accessing a web page using the mobile communication terminal, the graphic content stored as a temporary Internet file is converted into a file format having a high compression rate and stored, and the same web page is stored. By converting and displaying the original file format when reconnecting, the web page access speed can be improved while increasing memory usage efficiency.
