2 is a flowchart illustrating a data transmission method to a mobile device according to the prior art.

3 is a view for explaining a data data file applied to the divided data transmission method according to an embodiment of the present invention.

4 is a flowchart illustrating a method of transmitting divided data to a mobile device according to an embodiment of the present invention.

The present invention relates to a data transmission method, and more particularly, to a data transmission method to a mobile device.

Recently, the use of mobile devices has become common due to the activation of mobile devices, and it is possible to use mobile devices regardless of region, time and space constraints. In addition, mobile devices, such as IMT-2000, can transmit and receive text information as well as image information.

As such, as the application range of the mobile device is expanded, as shown in FIG. 1, many users frequently request specific data data through the mobile device.

2 is a flowchart illustrating a data transmission method to a mobile device according to the prior art. Referring to FIG. 2, a data transmission method of a conventional mobile device will be described.

First, when a transfer request of the data data file 11 is generated from the specific mobile device 20 to the main server 10, the main server 10 recognizes the transfer request (S101). In operation S203, it is determined whether the data data file 11 received from the specific mobile device 20 is being transmitted to the other mobile device 20 ′. If the data data file 11 is in the state of being transmitted, after waiting for a predetermined time (S205), it is determined whether the transmission to the other mobile device 20 'is completed (S207). After the transmission to the other mobile device 20 'is completed, the file is transferred to the specific mobile device 20 (S209).                         

However, as shown in FIG. 2, in the data transmission method according to the related art, after the data transmission to another mobile device 20 ′ previously requested to be transmitted is completed, data to a specific mobile device 20 is completed. The transmission is advanced. For example, if the time required for data transmission to one mobile device is T, and the data files are requested to be transmitted from five mobile devices at about the same time, the data transmission to the mobile device that requested the latest transmission is 4T. After elapse, it progresses.

Therefore, the data transmission method to the mobile device according to the prior art has a problem that the waiting time for data transmission increases.

An object of the present invention is to solve the problems of the prior art, to provide a data transmission method to a mobile device that minimizes the waiting time for data transmission.

One aspect of the present invention for achieving the above technical problem relates to a split data transmission method for providing a predetermined data data file from the main server to a plurality of mobile devices. The split data transmission method of the present invention comprises the steps of: dividing the data data file into n parts (where n is a natural number of 2 or more) and providing the main server to access it; B) the main server recognizing a request for transmission of the data data file from a specific mobile device; C) determining the number (m) of other mobile devices currently transmitting the data data file; And if the m is smaller than the n, transmitting the part file which is currently not transmitted to the specific mobile device.

For a better understanding of the present invention and its operational advantages, and the objects attained by the practice of the present invention, reference should be made to the accompanying drawings, which illustrate preferred embodiments of the invention, and the accompanying drawings. In understanding each of the figures, it should be noted that like parts are denoted by the same reference numerals whenever possible. In addition, in the following description, numerous specific details, such as specific processing flows, are described to provide a more general understanding of the invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. Incidentally, detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a diagram for explaining a data data file 11 applied to a method of transmitting divided data according to an embodiment of the present invention. The data data file 11 is divided into n parts. Each part of the data data file 11 can be independently accessed from the main server 10 and the mobile devices 20 and 20 'of FIG. 1.

4 is a flowchart illustrating a method of transmitting divided data to a mobile device according to an embodiment of the present invention. With reference to Fig. 4, the divided data transmission method of the present invention is described.

First, as shown in FIG. 3, a data data file divided into n parts is provided to the main server 10 (S401). As described above, each part of the data data file is accessible from the main server 10 and each of the mobile devices 20 and 20 '. Then, when a transfer request of the data data file 11 is generated from the specific mobile device 20 to the main server 10, the main server 10 requests the transfer of the data data file from the specific mobile device. It is recognized (S403). In operation S405, it is determined whether the data data file 11 received from the specific mobile device 20 is being transmitted to the other mobile device 20 ′.

If the data data file 11 is being transmitted, the number m of other mobile devices currently transmitting the data data file 11 is determined to determine whether m is smaller than n. It is determined (S407). If m is a value smaller than n, among the parts of the data data file 11, a part that is not currently being transmitted is searched (S411), and the searched part is converted into the specific mobile device 20; 20 ') (S413).

As a result of the determination in step S409, when m is not smaller than n (here, m is the same value as n), after the predetermined time has elapsed (S415), step S407 is performed again.

In addition, when there is no mobile device 20 'that transmits the data data file as a result of the determination in S405, step S411 is performed.

According to the data division transmission method of the present invention as described above, the waiting time for data transmission is significantly reduced. If a transmission request for the same data data file occurs in five mobile devices at the same time, if n is 5 or more, data can be transmitted without waiting. In addition, even when data transmission requests are generated simultaneously from five or more mobile devices, if some parts of the data file are not transmitted, the data can be transmitted immediately. do.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

According to the divided data transmission method of the present invention as described above, by dividing the data data file to be transmitted into a plurality of parts and storing them in an accessible state, a transmission request for the same data data file is generated from a plurality of mobile devices at the same time. Even if it is, the waiting time in the mobile device can be significantly reduced by first transmitting the part that is not in the state of being transmitted.
