Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a file synchronization system according to Embodiment 1 of the present invention. In this system, the client PC 1 synchronizes the file 21 b in the predetermined directory 21 a of the mobile terminal device 2 and the file 31 b in the predetermined directory 31 a of the server device 3.

  The client PC 1 is a personal computer operated by a user. An input device 5 such as a keyboard and a mouse and a display device 6 such as a liquid crystal display are connected to the client PC 1. The client PC 1 includes an interface circuit 11, a communication circuit 12, a network communication processing unit 13, a synchronization processing unit 14, and a desktop processing unit 15. The interface circuit 11 is a circuit that performs data communication with a peripheral device based on the peripheral device interface standard. As the interface circuit 11, a wired circuit such as USB (Universal Serial Bus) or IEEE1394, or a wireless circuit such as infrared communication or Bluetooth (trademark) is used. For example, by using a USB mass storage class, file operation of a device connected to the client PC 1 can be realized. The communication circuit 12 is a circuit capable of data communication with the server device 3 via the computer network 4. As the communication circuit 12, a network interface card, a modem, or the like is used as appropriate. The computer network 4 includes, for example, a communication path for connecting to such a network in addition to a network such as the Internet and a LAN.

  The client PC 1 has a built-in computer, and the network communication processing unit 13, the synchronization processing unit 14, and the desktop processing unit 15 have programs stored in a recording medium (memory, hard disk, etc.) (not shown) in the client PC 1. It is a processing unit realized by being executed by a processor (not shown).

  The network communication processing unit 13 is a processing unit that controls the communication circuit 12 and performs data communication with the server device 3 according to a predetermined communication protocol.

  The synchronization processing unit 14 is a processing unit that controls file synchronization between the mobile terminal device 2 and the server device 3.

When the icon 45 is clicked (or double clicked), a window 46 is displayed in the display area 42, and a list of icons 46a corresponding to the files 31b included in the directory 31a is displayed in the window 46. As described above, in the desktop environment by the desktop processing unit 15, user file operations (addition, deletion, movement, change, change, etc.) are held in the server device 3 without being held in the client PC 1. File contents, file list, etc.). For example, when the file 31b is an image file and the icon 46a is clicked (or double-clicked), the desktop processing unit 15 acquires the file 31b from the server device 3, and acquires an image based on the file 31b. It is displayed in the display area 42.

  The mobile terminal device 2 is an electronic device that can be carried by the user, such as a mobile phone, a PDA (Personal Digital Assistant), a music player, and a digital camera. As an example of the portable terminal device 2, a large-capacity memory stick using a USB mass storage class may be considered. The mobile terminal device 2 includes a data storage device 21, an interface circuit 22, and a file operation unit 23. The data storage device 21 is a device having a recording medium such as a nonvolatile memory or a hard disk. A file system is constructed in the data storage device 21, and a file 21b is stored in the directory 21a. The interface circuit 22 is a circuit capable of data communication based on an interface of the same standard as the interface circuit 11. The file operation unit 23 is a processing unit that executes writing, reading, and changing of a file with respect to the data storage device 21 in accordance with a command supplied via the interface circuit 22. The file operation unit 23 may be realized by an ASIC (Application Specific IC) or the like, or may be realized by executing a program by a built-in processor. For example, a program that implements the file operation unit 23 may be installed in a mobile phone manufactured by NTT Docomo, and used as the mobile terminal device 2.

  The server device 3 is a server that can store a user file and can operate the user file in a desktop environment provided by the desktop processing unit 15 of the client PC 1.

  The network communication processing unit 33 is a processing unit that controls the communication circuit 32 and performs data communication with the client PC 1 according to a predetermined communication protocol.

  The file operation unit 34 has a function as an HTTP server, and is a processing unit that transmits and receives file operation commands, responses, and files in accordance with HTTP, and executes file operations in accordance with the commands. The file operation command and response are transmitted and received between the file operation unit 34 and the synchronization processing unit 14 of the client PC 1 and between the file operation unit 34 and the desktop processing unit 15. The synchronization processing unit 14 of the client PC 1 uses file operation commands and responses in the same format as those used between the desktop processing unit 15 and the file operation unit 34.

  Next, the operation of each device of the system and the file synchronization process will be described. FIG. 3 is a flowchart for explaining the operation of the synchronization processing unit 14 of the client PC 1 in FIG.

  In the client PC 1, the synchronization processing unit 14 monitors whether or not the mobile terminal device 2 is electrically connected to the interface circuit 11 (step S1).

  And the synchronization process part 14 will perform the initial synchronization process (synchronization process A), if the connection of the portable terminal device 2 is detected (step S2).

  In the synchronization process A, first, the synchronization processing unit 14 transmits a command for requesting a file list in a predetermined directory 21 a of the data storage device 21 of the mobile terminal device 2 to the mobile terminal device 2 via the interface circuit 11. . In the mobile terminal device 2, the command is received by the file operation unit 23 via the interface circuit 22. Correspondingly, the file operation unit 23 accesses the data storage device 21, acquires the file list in the predetermined directory 21a, and transmits the file list via the interface circuit 22 as a response to the command. The synchronization processing unit 14 receives the file list via the interface circuit 11. Further, the synchronization processing unit 14 transmits a command for generating a directory 31 a corresponding to the directory 21 a of the mobile terminal device 2 to the server device 3. This command is received by the file operation unit 34 via the network communication processing unit 13, the communication circuit 12, the computer network 4, the communication circuit 32, and the network communication processing unit 33. The file operation unit 34 generates a directory 31a in the data storage device 31 in accordance with the command. Thereafter, the synchronization processing unit 14 sends a command to the mobile terminal device 2 to acquire all the files 21b in the file list, and causes the files to be written in the directory 31a of the server device 3. As described above, in the synchronization process A, when the portable terminal device 2 is connected, the directory 31a corresponding to the directory 21a of the portable terminal device 2 is generated in the server device 3, and the file 21b in the directory 21a is copied to the directory 31a. The Note that, hereinafter, the exchange of commands and responses between the synchronization processing unit 14 and the mobile terminal device 2 and the exchange of commands and responses between the synchronization processing unit 14 and the server device 3 are the same paths as described above. Is done through.

  On the other hand, the desktop processing unit 15 of the client PC 1 monitors a predetermined storage area of the server device 3 by polling. When the directory 31a is generated, the directory 31a is detected, and as shown in FIG. The display of the indicated icon 45 is started.

  When the synchronization process A is completed, the synchronization processing unit 14 starts monitoring the directory 21a of the mobile terminal device 2 and the directory 31a of the server device 3 (step S3). In monitoring the directory 21a of the portable terminal device 2, the synchronization processing unit 14 periodically acquires a file list in the directory 21a by polling and determines whether there is an increase, decrease, or change of files in the directory 21a (step S4). ). Further, in the monitoring of the directory 31a of the server device 3, the synchronization processing unit 14 periodically acquires a file list in the directory 31a by polling, and determines whether there is an increase, decrease, or change of a file in the directory 31a (step S5). Further, the synchronization processing unit 14 monitors whether or not the mobile terminal device 2 is connected to the client PC 1 (step S6).

  When the synchronization processing unit 14 detects any increase, decrease, or change of the file in the directory 21a of the mobile terminal device 2 due to other than the synchronization processing, the synchronization processing unit 14 executes the synchronization processing B (step S7). FIG. 4 is a diagram for explaining the synchronization process B in the first embodiment.

  As illustrated in FIG. 4, in the synchronization process B, when an increase or change in the file 21 b is detected, the synchronization processing unit 14 acquires the added or changed file 21 b from the mobile terminal device 2 and stores it in the server device 3. Supply. In the server device 3, the file operation unit 34 adds the added file 21b to the directory 31a, and overwrites the file before the change in the directory 31a with the changed file 21b. When the decrease in the file 21 b is detected in the synchronization process B, the synchronization processing unit 14 transmits a command for deleting the deleted file 21 b to the server device 3. In the server device 3, the file operation unit 34 deletes the file 31b specified by the command. In this way, the change in the contents of the directory 21a of the portable terminal device 2 is reflected in the contents of the directory 31a of the server device 3 by the synchronization process B, and synchronization between the two is ensured.

  On the other hand, the desktop processing unit 15 monitors the directory 31 a of the server device 3, and when the contents of the directory 31 a are displayed in the window 46, the change in the contents of the directory 21 a of the mobile terminal device 2 is changed. When reflected in the contents of the directory 31a, the display state of the window 46 also changes accordingly. FIG. 5 is a diagram illustrating an example of a change in the display state of the window 46 according to a change in the contents of the directory 21a of the mobile terminal device 2 in the desktop environment according to the first embodiment. When one file 21b is added to the directory 21a from the state in which there is no file in the directory 21a, the display state of the window 46 for displaying the contents of the directory 31a is changed from the display state shown in FIG. The display state changes to 5 (B). In the display state in FIG. 5B, an icon 46 a indicating the file 31 b in the server device 3 corresponding to the file 21 b added in the mobile terminal device 2 is displayed in the window 46.

  When the synchronization processing unit 14 detects any increase, decrease, or change of the file in the directory 31a of the server device 3, the synchronization processing unit 14 executes the synchronization process C (step S7).

  The increase, decrease, and change of the file in the directory 31a of the server device 3 due to other than the synchronization process occur, for example, by a user operation in the desktop environment of the client PC1. FIG. 6 is a diagram illustrating an example of a change in the display state of the window 46 in response to a change in the contents of the directory 31a of the server device 3 in the desktop environment according to the first embodiment.

  For example, as shown in FIG. 6A, in the desktop environment of the client PC 1, a file icon 47 in another directory of the server device 3 displayed on the desktop by drag and drop based on the GUI is displayed in the directory. When moved to the window 46 indicating 31 a, the desktop processing unit 15 transmits a command to add the file to the server device 3. In the server device 3, the file operation unit 34 adds the received file to the directory 31a in accordance with the command. Since the desktop processing unit 15 monitors the directory 31a of the server device 3, when the file addition processing for the server device 3 is completed, if the contents of the directory 31a are displayed in the window 46, the directory processing unit 15 A change in the content of 31a is detected. Therefore, the display state of the window 46 changes as shown in FIG.

  As described above, when the contents of the directory 31a change, the synchronization process C is executed. FIG. 7 is a diagram for explaining the synchronization process C in the first embodiment.

  As shown in FIG. 7, in the synchronization process C, when an increase or change in the file 31 b is detected, the synchronization processing unit 14 acquires the added or changed file 31 b from the server device 3 and stores it in the mobile terminal device 2. Supply. In the mobile terminal device 2, the file operation unit 23 adds the added file 31b to the directory 21a, and overwrites the file before the change in the directory 21a with the changed file 31b. When the decrease in the file 31b is detected in the synchronization process C, the synchronization processing unit 14 transmits a command for deleting the deleted file 31b to the mobile terminal device 2. In the mobile terminal device 2, the file operation unit 23 deletes the file 21b specified by the command. In this way, the change in the contents of the directory 31a of the server device 3 is reflected in the contents of the directory 21a of the mobile terminal device 2 by the synchronization process C, and synchronization between the two is ensured.

  Further, the synchronization processing unit 14 executes the synchronization release processing when the mobile terminal device 2 is not connected to the client PC 1, that is, when the connection between the mobile terminal device 2 and the client PC 1 is released (step S9). After executing the synchronization release processing, the synchronization processing unit 14 returns to the standby state in step S1.

  In the synchronization cancellation process, the synchronization processing unit 14 transmits a command to the server apparatus 3 to delete the directory 31a corresponding to the mobile terminal device 2 that has been disconnected. In the server device 3, when receiving the command, the file operation unit 34 deletes the designated directory 31a and all the files 31b in the directory 31a.

  As described above, according to the first embodiment, the synchronization processing unit 14 as the connection detection unit detects that the mobile terminal device 2 is connected, and the synchronization processing unit 14 as the synchronization processing unit While the mobile terminal device 2 is connected, the directory 21a of the mobile terminal device 2 and the directory 31a in the server device 3 are monitored, and the contents of the two directories 21a and 31a are synchronized. Thereby, the client PC 1 automatically executes file synchronization between the mobile terminal device 2 and the server device 3 that are not directly connected by monitoring both file storage areas (that is, the directories 21a and 31a). be able to.

  Further, according to the first embodiment, the directory 31a of the server device 3 is a file storage area whose contents are manipulated in a desktop environment based on the GUI in the client PC 1. Thereby, the contents of the directory 21a of the mobile terminal device 2 can be operated in a desktop environment where the user file is stored on the server side.

  Further, according to the first embodiment, the synchronization processing unit 14 uses the same command group as the command group used when the contents of the directory 31a are operated in the desktop environment based on the GUI in the client PC 1. The directory 31a is monitored and synchronized. Thus, since the same command group as the existing command group used in the desktop environment is used, this file synchronization can be realized without adding a processing system of the command group for the synchronization process in the server device 3. Can do.

  Further, according to the first embodiment, when the synchronization processing unit 14 detects that the mobile terminal device 2 is connected, the synchronization processing unit 14 refers to the contents of the directory 21 a of the mobile terminal device 2 and stores the directory 31 a in the server device 3. And synchronize by reflecting the contents of the directory 21a of the portable terminal device 2 to the directory 31a. Thereby, the directory 21 a of the mobile terminal device 2 can be automatically mounted on the file system of the server device 3.

It may be. In this case, when a command for acquiring the main body of the file 21b is received from the desktop processing unit 15, the file operation unit 34 notifies the synchronization processing unit 14 of the command, and the synchronization processing unit 14 The file main body is acquired from and transmitted to the file operation unit 34. When the file operation unit 34 receives it, it transfers it to the desktop processing unit 15.

  For example, when addition / deletion of the file 21a of the mobile terminal device 2 by the client PC 1 is prohibited, the directory 21a in the mobile terminal device 2 and the directory 31a in the server device 3 to be monitored are compared. The file is added / deleted to / from the directory 21a only when adding / deleting the file to / from the directory 31a, or the file is added / deleted to / from the directory 31a only when adding / deleting the file to / from the directory 21a. May be performed.

  Further, there may be a plurality of directories 21a in the mobile terminal device 2 and directories 31a in the server device 3 to be monitored.

  Further, in each embodiment, the synchronization processing unit 14 and the desktop processing unit 15 detect changes in the contents of the directories 21a and 31a by polling. However, the server device 3 and / or the mobile terminal device detects a predetermined event occurrence. 2 may notify the synchronization processing unit 14 and / or the desktop processing unit 15, and the synchronization processing or the like may be executed using the notification as a trigger.

  In each embodiment, the server device 3 holds a table indicating the correspondence between the user ID and the user-dedicated storage area of the user ID in the data storage device 31, and the synchronization processing unit 14 and the desktop processing unit 15 may transmit the user ID to the server device 3, and the file operation unit 34 of the server device 3 may operate the file in the directory 31a in the storage area corresponding to the user ID. Thereby, the files of a plurality of users are managed independently for each user. In addition, when managing a file for every user group, a file should just be managed by a group ID and a user group exclusive storage area instead of a user ID and a user exclusive storage area.

  In each embodiment, the file list displayed in the desktop environment window 46 may be a text format list instead of the icon list as shown in FIG.

  In each embodiment, in the file synchronization between the directory 21a and the directory 31a, it is not necessary to synchronize all the files 21b and 31b, and only some of the files 21b and 31b are synchronized. You may do it.

  In each embodiment, the directory 31a is created when the portable terminal device 2 is connected, and the directory 31a is deleted when the connection is released. Instead, the portable terminal device 2 is connected and released regardless of the connection. The server device 3 may continuously hold the directory 31a. In that case, when the mobile terminal device 2 is connected, only the copy of the file in the directory 21a to the directory 31a is executed, and when the connection is released, only the file in the directory 31a is deleted.

  The present invention is applicable to, for example, a system for managing user files on the web server side, web groupware, and the like.
