Method for sharing memory of terminals and device for the same

The present invention relates to the sharing of storage space, and more particularly, to a method and apparatus for sharing a portion of the storage space between a plurality of terminals coupled via a communication network.

In recent years, in addition to the hard disk or external hard disk attached to your computer, USB memory, etc., the storage space provided by a specific server (for example, web hard) on the web in order to easily utilize the storage space in any internet-enabled space. The use of (for example, hard disks) is increasing. A general method of operating a hard disk on the web is a method of allowing a content provider server to distribute a hard disk connected to a server operated by the user to a plurality of users.

In particular, the storage space on the web is mainly used to share a large amount of data that can not be received by email. In other words, if you have more than a few tens of megabytes of data that aren't easily received by email, you're using storage on the Web.

In addition, if the user is a place where the Internet is available, there is an advantage that users can check files such as text, images, and videos stored in the storage space on the web anytime, anywhere, and users using the storage space on the web are increasing.

Moreover, in recent years, the use of digital cameras, camcorders, mobile phones with digital camera functions, and the like has increased, and the amount of multimedia data such as images and videos has increased. Accordingly, users store and manage multimedia data such as images and videos taken or taken by themselves using a removable storage device such as a USB memory or an external hard drive or by using a storage space on the web. Recently released mobile communication terminals such as mobile phones are equipped with a digital camera function and memory, it is possible to check the multimedia data such as images, videos anytime and anywhere. However, in order to accommodate a large number of image and video files in a mobile terminal, there is still a limitation of memory, and there is a inconvenience in that a large amount of multimedia files stored in a storage space on a computer or a web must be moved to a memory of a mobile terminal. do.

In addition, when managing multimedia data using a storage space on the web, in order to access the multimedia data, a user must log in to a content provider server that provides the storage space. Therefore, if you want to provide the data on the web to others, it is necessary to inform others of the ID and password to the content provider server may cause security problems accordingly.

As a technique for solving the problem, a method of sharing data without a separate login procedure using a server has been proposed, but similarly, by using the server, security problems such as hacking of data still remain. do.

In addition, a method of setting a part of a storage space of the terminal itself as a shared space and accessing other terminals through a communication network to use data stored in the shared space has been proposed. It only grants authority, and uses only shared data rather than using the storage space itself.

It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the specification and claims. The description will be omitted.

1 and 2 are schematic diagrams illustrating an entire system for sharing a storage space of terminals in each embodiment of the present invention.

Referring to FIG. 1, terminals 10-1, 10-2,..., 10-n, hereinafter referred to as 10, are terminal devices having a communication function as a communication network. It may be a personal portable terminal device such as a PDA, a tablet, and the like, and each terminal may be coupled through a communication network to transmit and receive data to and from each other.

In particular, each terminal 10 according to the present embodiment may set some or all of the provided storage means as shared spaces (12-1, 12-2, ..., 12-n, hereinafter referred to as 12) In the set shared space 12, a file to be shared is divided and stored.

For example, for convenience of understanding, when the first terminal 10-1 wants to share one video file, the first terminal 10-1 divides the video file into a plurality of pieces and divides each of the divided video files. Data (hereinafter referred to as divided data) is transmitted to the other terminals 10-2, ..., 10-n, respectively, and the other terminals 10-2, ..., 10-n receiving the corresponding data The partitioned data will be stored in its shared space. Subsequently, when any second terminal 10-2 attempts to access the corresponding video file, other terminals 10-1 and 10-3 storing divided data except for the second terminal 10-2. , ..., 10-n transmits the divided data stored therein to the second terminal, and the second terminal 10-2 merges the received respective divided data to display the first moving image file. You can create it.

In other words, each of the terminals set to share the storage space, if there is data to be shared, by dividing the data to be transmitted to other terminals, the data is divided and stored in each of the plurality of terminals.

According to the entire system according to FIG. 1, each terminal 10 stores access information (such as an IP address or a phone number) of other terminals (hereinafter referred to as member terminals) that share a storage space. By using the access information it is possible to send and receive data with the member terminals.

Referring to FIG. 2 according to another embodiment, the terminals 10 may transmit and receive data with member terminals via a relay server 50 connected through a communication network. The relay server 50 stores member information (eg, subscriber information, terminal access information, etc.) of terminals 10 that have promised sharing of storage spaces with each other, and stores data between terminals 10. Relay the transmission and reception.

Hereinafter, a process of sharing a storage space in the terminal 10 will be described in detail.

3 and 4 are flowcharts illustrating a process of storing a shared file in a terminal according to an embodiment of the present invention.

First, referring to FIG. 3, according to an embodiment, when a storage command for a shared file is input to a shared space (hereinafter, referred to as a self-shared space) (S310), the terminal uses the number of terminals using a shared service together. The shared file is divided (S320). As an easy example, if the number of terminals using the same shared service is ten, the shared file may be divided into ten. File division may be divided into blocks, or may be divided into a number of packet units suitable for a communication protocol, and may be variously divided according to operation. It will be more obvious.

The terminal generates data information for each divided data, for example, how many data of the shared file is stored, to which terminal each split data is stored, and what type of file the shared file is (S330). By using the above data information, the terminal can generate the original shared file by merging the split data acquired from other terminals. This will be described in detail later, but the data information may be implemented in the form of a header of the divided data (see FIG. 6). Hereinafter, for convenience of description, the data information is included as the header information in the divided data. An example will be described.

The terminal transmits the divided data including the data information to the member terminal (S340). In this case, the terminal may transmit different pieces of divided data to member terminals, but any terminal may later become incapable of communication or may lose or lose the divided data itself. It can also be sent to the member terminal. For example, in case of generating 10 divided data by dividing a shared file, the terminal stores one divided data in its own shared space and transmits the remaining data to nine member terminals in the storage space of each member terminal. There may be a method of storing each, and as described above, by transmitting two or more pieces of divided data to each member terminal, a plurality of member terminals may store the same divided data.

The member terminals that receive the divided data store the divided data in the shared space and transmit a return message to the terminal. Therefore, when the terminal receives all of the above return messages from the member terminal, the terminal completes the storing (S350).

Although omitted in the embodiment with reference to the drawings, of course, the step of setting a shared space according to some or all of the provided storage medium, and setting a member terminal that can store or acquire data in the shared space may be preceded. Of course.

In the present embodiment, all the terminals store the divided data for one shared file. Alternatively, the divided data is stored in only some of the terminals using the shared service according to the size and type of the file. May be used.

Referring to FIG. 4, which illustrates an embodiment thereof, when a storage command for a shared file is input (S410), the terminal divides the shared file according to a preset rule according to the size of the shared file (S420). For example, if the divided data is set to generate 50 megabytes (Mbytes), when the shared file is 220 megabytes, 4 divided data having a size of 50 megabytes and 1 divided data having a size of 20 megabytes The dog is created.

The terminal selects a member for storing the divided data generated using the storage space information of the member terminals using the shared service together (S430). That is, each member terminal measures the information about the total size of its shared space, the size of the currently stored data and the size of the storage space, and uses the information on the other member terminals as its storage space information. You can inform. In this case, the terminal may request and receive the storage space information from another member terminal at this point in time for storing the shared file, or may acquire and have the storage space information in advance.

According to an embodiment, in this step, a terminal having a large available storage space may be selected first. Here too, it is obvious that the same divided data can be transmitted to a plurality of other terminals.

In the present embodiment, the split data is generated and transmitted to correspond to the size of the shared file. However, the type of the shared file may be used. For example, a method of dividing the terminals using the shared service into groups and transmitting the divided data only to the terminals belonging to any group according to the type of the shared file may be used. For example, if the shared file is a video file, the divided data should be sent and stored only to the terminals of group A. If the shared file is a music file, the divided data is stored in the storage space of the terminals of the group B and the group C if the image file is an image file. Can be stored. In other words, the terminal for storing the shared file is selected according to the type of the shared file.

Of course, in this case, the terminal may transmit information on the divided data to the remaining member terminals that do not store the divided data so that other terminals that do not store the divided data can also acquire the corresponding shared file. That is, even if the divided data is not stored, the shared file can be used at any time by having information about where each divided data of the shared file is stored.

Referring back to the drawings, the terminal transmits the divided data to the selected member terminal (S440). The member terminals that receive the data store the divided data in their storage space.

Hereinafter, a process of generating a shared file using the divided data by an arbitrary member terminal receiving the divided data will be described.

5 is a flowchart illustrating a process of generating a shared file using split data in a terminal according to an embodiment of the present invention, and FIG. 6 is an exemplary diagram showing header information of split data according to an embodiment of the present invention. .

First, referring to FIG. 6, as header information of split data, a shared file information field 610, a split number field 620, and other data information fields 630-1, 630-2,. , Hereinafter referred to collectively as 630).

In the shared file field 610, identification information such as the name or serial number of the shared file for identifying the shared file may be stored, and related information about the type, data amount, etc. of the shared file may be stored. In the split number field 620, split data identification information for identifying the number of pieces of split data is stored.

Finally, each other data information field 630 stores information on the terminal storing the remaining divided data (such as an IP address or a phone number), and corresponding partition data identification information (ie, information about the number of data). .

Referring to FIG. 5, when an import command for a shared file according to the divided data is input (S510), any terminal storing divided data checks the header information of the divided data and stores the divided data in its shared space. In order to acquire the remaining divided data other than the data, each divided data is requested to the member terminals through the communication network (S520).

For a predetermined time, the terminal receives respective divided data from the member terminals (S530), and when the predetermined time has elapsed, it determines whether all the divided data have been received (S540).

When all the divided data is received, the terminal merges all the divided data using the header information to generate a shared file (S550).

On the contrary, when there is the split data not received, the terminal requests the split data to another member terminal other than the terminal requested in S520 among the member terminals having the split data not received (S560). That is, as described above, since a plurality of terminals own the same divided data, when the response is not received from the first requested member terminal, the same divided data may be requested to another member terminal. Of course, before proceeding to S560, it is possible to request the split data again with the member terminal requested in S520 once again, and may proceed to S560 only when there is no response for a predetermined number of times (for example, two times).

According to the present embodiment, all the member terminals using the shared service do not need to store all the data according to the shared file, but only some of them are stored, and the rest are stored in the storage spaces of other member terminals at any time. Collect and use shared files.

Therefore, not only can the file store a larger capacity than the provided storage space, but also can easily share the data with other terminals without a separate server device, and moreover, the server that stores the shared file, such as Web hard Compared to using it, it provides the advantage of strengthening security by fundamentally blocking the way others can access the shared file.

Hereinafter, the configuration of the terminal will be described.
