Description

  The present invention relates to a remote file access terminal, a storage terminal, a remote file access method, and a remote file access terminal program for causing a file on a storage terminal to be processed by an application on the storage terminal.

  In recent years, various services are provided to users by connecting a mobile terminal connected to a public network to a Web server or the like. In particular, with the advent of smartphones (high-function mobile phones), it has become possible to perform advanced services that have been provided for personal computers with mobile phones.

  In addition, information sharing has become increasingly popular with the spread of information terminals and the improvement of line speed. Conventionally, sharing of documents and URLs by e-mail has been performed, but now it is possible to share even large capacity files such as voice and moving images.

  However, even if a file is shared, the received file cannot be processed if there is no application for reproducing and processing the file at the sharing destination terminal. In addition, when the receiving terminal is a mobile terminal or when the file capacity is extremely large, there is a problem that it takes time to send and receive the file and the file cannot be shared smoothly.

  In response to such a problem, a file transfer system for mobile phones is disclosed that enables a large file to be transferred to a mobile phone without being reduced or compressed and viewed on the received mobile phone.

  In Patent Document 1, a file format determination unit that determines a file format of a received file, a file format conversion unit that converts a file format to a predetermined image file format when the file format is not a predetermined image file format, and a file After the format is converted into a predetermined image file format, the number of pixels in the vertical and horizontal directions is acquired, divided into a plurality of tile-shaped child images of a predetermined size, and file division means for assigning sequential file names; Creates an e-mail that includes storage means for storing the position information for specifying the positional relationship in each image file after division and the entire image in a specific folder, and at least link information to the URL of the folder in the text. And an e-mail issuing means for transmitting to the recipient's mobile e-mail address. It is shown.

  According to the technique described in Patent Document 1, it is possible to perform high-speed sharing without reduction or compression even when the line speed between the sharing source terminal and the sharing destination terminal is low. However, in the method described in Patent Document 1, since it is assumed that the file is an image, and since it passes through the transfer server once in transmission / reception, the time when the file is transmitted from the sharing source terminal to the transfer server, There is a problem that it takes time for each file to be independently transmitted from the transfer server to the sharing destination terminal, and there is a possibility that it takes time as a whole.

  Therefore, the inventor of the present invention reproduces and processes the file on the storage terminal on the storage terminal that is the sharing source terminal instead of the sharing destination terminal, so that the sharing destination terminal directly processes the target file. We focused on whether it can be processed. In addition, the inventor of the present invention does not transmit / receive the file contents themselves in the sharing process, but only shares the processing contents by screen sharing, so that even if the original file capacity is extremely large, We focused on the fact that the capacity can be greatly reduced and processing can be started immediately.

  In view of these problems, the present invention causes a file on a storage terminal connected to be communicable to be processed by an application on the storage terminal that is the sharing source terminal, not the sharing destination terminal, and displays the processing contents on the screen.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. This is merely an example, and the technical scope of the present invention is not limited to this.

[Outline of Remote File Access System 1]
FIG. 1 is a schematic diagram for explaining an outline of a remote file access system 1 which is a preferred embodiment of the present invention. The remote file access system 1 includes a remote file access terminal 10, a storage terminal 50, and a public network 3 (Internet network, third generation, fourth generation communication network, etc.).

  First, the remote file access terminal 10 selects a file to be processed and requests an arrangement structure from the storage terminal 50 in order to specify a location (step S01). At this time, since it takes time to scan the arrangement structure of all the files, the reference position and the depth of the hierarchy to be read may be specified, or may be determined in advance on the storage terminal 50 side.

  In response to the request, the storage terminal 50 transmits the file arrangement structure to the remote file access terminal 10 (step S02). The remote file access terminal 10 that has received the arrangement structure displays the arrangement structure on the display unit, and the user designates a file to be processed on the arrangement structure.

  In the present invention, file processing refers to acquisition, reading, editing, writing, execution, and other file access of detailed information via a specific application or OS, but is not limited thereto.

  When the remote file access terminal 10 receives the designation of the file, the remote file access terminal 10 transmits the location on the file system of the file, so-called file path, to the storage terminal 50 (step S03). At this time, similarly, the location of the application that processes the target file may be transmitted as an application path.

  The storage terminal 50 that has received the file path and the application path starts processing the target file using the application specified by the application path (step S04). Here, when the application path is not received, an application defined in advance on the storage terminal 50 may be used. The application may be in a format that can be executed on the OS, or may be a processing system of the OS itself.

  Finally, the remote file access terminal 10 starts screen sharing with the storage terminal 50 (step S05). By doing so, the processing result can be referred regardless of the capacity of the target file itself. Further, even if there is no application capable of processing the file on the remote file access terminal 10, the file processing can be executed. Here, in principle, the screen sharing is the entire screen of the storage terminal 50. However, when an application drawing range, for example, an application window can be specified, only the drawing range may be shared.

  The above is the outline of the remote file access system 1.

[System configuration of remote file access system 1]

It may be a typical information device or electronic device.

[Description of each function]
FIG. 3 is a diagram illustrating the functional blocks of the remote file access terminal 10 and the storage terminal 50 and the relationship between the functions.

  The remote file access terminal 10 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like as the control unit 11, and the communication unit 12 is, for example, WiFi compliant with IEEE802.11. (Wireless Fidelity compatible device or wireless device compliant with IMT-2000 standard such as 3rd generation mobile communication system, etc. (equipped with wired LAN connection).

  Further, the remote file access terminal 10 includes, as the input / output unit 13, a display unit configured to output and display data and images controlled by the control unit, a speaker that reproduces sound, and the like. Touch panel, keyboard, mouse, etc.

  In the remote file access terminal 10, the control unit 11 reads a predetermined program, thereby realizing the arrangement structure acquisition module 14, the file path transmission module 15, and the application path transmission module 16 in cooperation with the communication unit 12. In the remote file access terminal 10, the screen sharing module 17 is realized in cooperation with the communication unit 12 and the input / output unit 13 by the control unit 11 reading a predetermined program. In the remote file access terminal 10, the control unit 11 reads a predetermined program, thereby realizing a file designation receiving module 18 and an application designation receiving module 19 in cooperation with the input / output unit 13.

  Similarly, the storage terminal 50 includes a CPU, a RAM, a ROM, and the like as the control unit 51, and an IMT-device such as a WiFi compatible device compliant with IEEE 802.11 or a third generation mobile communication system as the communication unit 52, for example.

Realize. In the storage terminal 50, the control unit 51 reads a predetermined program, thereby realizing the screen sharing module 58 in cooperation with the communication unit 52 and the input / output unit 53.

[Remote file access processing]
FIG. 4 is a flowchart of remote file access processing executed by the remote file access terminal 10 and the storage terminal 50. The processing performed by the module of each device described above will be described together with this processing.

  First, the arrangement structure acquisition module 14 of the remote file access terminal 10 and the arrangement structure transmission module 54 of the storage terminal 50 execute an arrangement structure acquisition process in order to acquire the arrangement structure in the file system of the storage terminal 50 (step S11). ).

[Arrangement structure acquisition processing]
FIG. 5 is a flowchart of an arrangement structure acquisition process executed by the remote file access terminal 10 and the storage terminal 50. The processing performed by the module of each device described above will be described together with this processing.

  First, the arrangement structure acquisition module 14 of the remote file access terminal 10 transmits a reference directory as a reference for acquiring the arrangement structure and a maximum acquisition hierarchy to the storage terminal 50 (step S21), and transmits the arrangement structure of the storage terminal 50. The module 54 receives this (step S22).

  Similarly, the arrangement structure acquisition module 14 of the remote file access terminal 10 transmits an arrangement structure acquisition request to the storage terminal 50 (step S23), and the arrangement structure transmission module 54 of the storage terminal 50 receives the request (step S23). Step S24). The transmission / reception of the reference directory and the maximum acquisition hierarchy and the transmission / reception of the acquisition request may be performed simultaneously in one communication.

  Here, the reference directory may be consciously input by the user, or may be automatically specified, for example, the directory that lastly processed the file during the previous execution. The storage terminal 50 may perform any setting without receiving, but it is possible to specify the reference directory and the maximum acquisition hierarchy from the remote file access terminal 10 side, and by performing repeated acquisition, the sequential arrangement structure Acquisition is possible.

  Next, the arrangement structure transmission module 54 of the storage terminal 50 changes the current directory to a reference directory that is a reference for obtaining the arrangement structure (step S25). Then, the arrangement structure is acquired within the range of the maximum acquisition hierarchy (step S26). Here, since the directory structure is generally a tree structure, the maximum acquisition hierarchy is represented by an integer. Unless otherwise specified, each of the upper and lower ranges may be acquired. By using symbolic links, it is possible to realize a more complicated structure than a general tree structure.

  Finally, the arrangement structure transmission module 54 transmits the acquired arrangement structure to the remote file access terminal 10 (step S27), and the arrangement structure acquisition module 14 of the remote file access terminal 10 receives it (step S28). The above is the procedure of the arrangement structure acquisition process.

  Returning to the remote file access process, the remote file access terminal 10 displays the acquired arrangement structure on the screen, and the file designation receiving module 18 receives the designation of the processing target file (step S12).

  Next, the file path transmission module 15 of the remote file access terminal 10 transmits the file path to be processed to the storage terminal 50 (step S13), and the file path reception module 55 of the storage terminal 50 receives this (step S13). S14).

  Similarly, the remote file access terminal 10 displays the acquired arrangement structure on the screen, and the application designation receiving module 19 receives the designation of the application that processes the processing target file (step S15). Then, the application path transmission module 16 of the remote file access terminal 10 transmits the file path to be processed to the storage terminal 50 (step S16), and the application path reception module 56 of the storage terminal 50 receives this (step S17). ).

  FIG. 6 is an example of a screen of the remote file access terminal 10 that accepts input of file designation. The received arrangement structure 61 is shown on the screen, and the background of the currently selected hierarchy 62 is displayed in black. A directory or file can be selected using the pointer 63 or a tap. For example, a file is designated as a processing target file by double-tapping the file. Further, by depressing the button 64 for acquiring the upper hierarchy and the button 65 for acquiring the lower hierarchy, it is possible to acquire or update the arrangement structure based on the currently selected directory.

  Next, the file processing start module 57 of the storage terminal 50 starts processing the target file using the application specified by the received application path (step S18). Here, when the application path is not received, an application defined in advance on the storage terminal 50 may be used.

  In addition, an application for processing a file is not only an executable application. For example, when the extension of a file to be processed is “exe”, “bat”, or “sh”, the OS itself performs processing. It may be.

  Then, the screen sharing module 58 of the storage terminal 50 acquires screen display content and transmits it to the remote file access terminal 10, thereby starting screen sharing (step S19). Here, the display content range to be acquired may be the entire screen, or if the drawing range of the application can be specified such as a single window, only the drawing range is acquired and transmitted. You can do it.

  Finally, the screen sharing module 17 of the remote file access terminal 10 receives the display content from the storage terminal 50 and displays it on the display unit of the remote file access terminal 10 to perform screen sharing (step S20).

  FIG. 7 is an example of the screens of the remote file access terminal 10 and the storage terminal 50 that share the screen of only the drawing range of the application. Since the processing contents of the application are displayed in the window 71, only the window 71 is shared with the remote file access terminal 10 as the application drawing range and displayed as the window 72.

  In FIG. 7, the screens in the other ranges are not shared. For example, the location 74 where the folder 73 on the desktop is to be drawn is not displayed on the remote file access terminal 10. As a result, the amount of data transfer can be reduced, and at the same time, even if the screen resolutions of both terminals are different, the reduction ratio can be reduced.

  In the above processing procedure, the arrangement structure and the processing contents are shared as output, but the file itself is not transmitted or received at all. As a result, it is possible to perform file processing remotely regardless of the capacity of the file and regardless of whether the remote file access terminal 10 can process the file. The above is the procedure for remote file access processing.

  The means and functions described above are realized by a computer (including a CPU, an information processing apparatus, and various terminals) reading and executing a predetermined program. The program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, CD (CD-ROM, etc.), DVD (DVD-ROM, DVD-RAM, etc.), for example. In this case, the computer reads the program from the recording medium, transfers it to the internal storage device or the external storage device, stores it, and executes it. The program may be recorded in advance in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provided from the storage device to a computer via a communication line.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
