4 is a charge display diagram that charges according to the amount of received data for each service content.
The present invention relates to a distributed download control system and a method of a mobile communication terminal, and more particularly, to receive a multimedia content service by synchronizing a plurality of user terminals located in a short distance when receiving multimedia content from a mobile communication terminal. Afterwards, the present invention relates to a distributed download control system of a mobile communication terminal and a method for merging all of them to complete a single content.
Mobile communication terminals that have enabled multimedia display have become commonplace in recent years when IMT-2000 (International Mobile Telecommunications-2000) technology is being pushed forward.
In this way, the mobile communication terminal equipped with the multimedia function is larger than before and adopts a color LCD (Liquid Crystal Display) instead of a single color to enable video on demand (VOD). You can talk while watching the video of the other party.
However, in the related art, since the service fee for downloading multimedia contents using the multimedia terminal is very expensive, a problem arises that the terminal user is economically burdened.
As shown in FIG. 4, a service fee for downloading multimedia content using the multimedia terminal is charged according to the amount of data received for each service content.
For example, e-mail charges 6.5 won per packet of 512 bytes, and 2.5 won per packet of 512 bytes for movies (VOD).
Therefore, when a terminal user downloads and watches a VOD movie, a huge service fee of tens of thousands to hundreds of thousands of won is charged.
Accordingly, the present invention has been proposed to solve the above-mentioned problems. In the mobile communication terminal, when receiving multimedia content, a plurality of user terminals located at a short distance are synchronized with each other, and each of them receives a multimedia content service, and then merges all of them. An object of the present invention is to provide a distributed download control system and a method of a mobile communication terminal which complete one content.

In order to achieve the above object, the present invention provides a method of designating a server terminal among a plurality of terminals that will use a download service, obtaining content information using the designated server terminal, synchronizing the plurality of terminals, and the server. A terminal for dividing a multimedia content file using the content information to designate a location to be downloaded from each of the plurality of terminals, and the plurality of divided multimedia content files corresponding to the plurality of terminals according to the designated location; Independently downloading and storing the plurality of terminals, and each of the plurality of terminals merging the divided multimedia content files, wherein the divided multimedia content files respectively stored by the plurality of terminals are stored between the plurality of terminals. Prize Exchanging the divided multimedia content files and the downloaded divided multimedia content files by each of the plurality of terminals, and storing the merged multimedia content files by each of the plurality of terminals. Provided is a distributed download control method of a mobile communication terminal, including the merging step.
The present invention also provides a multimedia content server that provides a predetermined multimedia content file as a download, and downloads and stores the multimedia content file from the multimedia content server in synchronization with each other, and merges the divided multimedia content files. A plurality of terminals, wherein each of the plurality of terminals exchanges the divided multimedia content files between the plurality of terminals, merges the exchanged divided multimedia content files and the downloaded divided multimedia content files, and the plurality of terminals. A distributed download control system for a mobile communication terminal, including the plurality of terminals, each storing a merged multimedia content file is provided.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Currently, the download service uses a protocol called HyperText Transfer Protocol (HTTP).
In the download service, the mobile communication terminal can designate the start and end positions of the content to be downloaded in the "Range" header in the HTTP GET method.
If the start position is specified, the multimedia content server transmits the multimedia content as a download from the designated position.
In the present invention, if any one of the N (multiple) terminals is designated as a server terminal, then predetermined information (for example, size information of the total file to be downloaded) is requested to the multimedia content server using the designated server terminal. The server searches the data file (content file) stored in the database to find out the size information of the total file to be downloaded of the corresponding data file and transmits it to the server terminal.
In the present invention, when there are several (N) mobile communication terminals at a short distance, the total file size (S) of the entire multimedia content is divided by the number of terminals (N), and each terminal divides the file size by S / N. Download it.
Each terminal downloads a file size divided by S / N, and then merges all the content files distributed in each terminal into one to complete one content file.
In this way, each terminal user can download and store the content that they want to download at a low cost (S / N).
Since the method of the present invention can be extended without limit to the number of terminals that can be interworked, at least two or more terminals can be used to use the download service at a rate that is at least 1/2 lower than that of the conventional method.

In this way, when three terminal users receive and store any arbitrary content download, the receiving burden is distributed to one third, thereby reducing the economic burden.
Meanwhile, in the above embodiment, data is exchanged between terminals using short-range communication such as infrared (IrDA), Bluetooth, and wireless LAN, but in another embodiment, various wired networks such as a USB cable may be used. Data exchange between terminals is also possible.
As described in detail above, the present invention synchronizes a plurality of user terminals located in a short distance when receiving multimedia content in a mobile communication terminal using short-range communication, receives a multimedia content service by dividing each of them, and then merges all of the predetermined content. By completing the above, it provides a useful effect that can be used with a small burden (1 / N) of the content files that you want to download each other between terminal users.
In addition, since the download time is actually reduced to 1 / N in the wireless network using the mobile communication terminal, the download speed felt by the user is increased by N times.
