Description

  The present invention relates to a file reservation management apparatus and method.

  Conventionally, files stored in a file server or the like that can be shared by a plurality of devices (editing devices) used by each of a plurality of users for editing files are edited by the same file by a plurality of editing devices. It is necessary to prevent conflicts of editing contents. In order to prevent conflicts in editing contents, there is a method of locking the file while the file stored in the file server or the like is being edited by the editing apparatus. By locking the file, it is impossible to edit the file from other than the corresponding editing device, and it is possible to prevent contention of editing contents between the editing devices.

Further, there is a method in which even a document file being edited by a certain editing device can be edited from another editing device (for example, Patent Document 1). According to this method, when a document file is shared by multiple editing devices and the document editing process is performed, if the editing device performs document editing and data change occurs, the editing request from other than the corresponding editing device is locked. The exclusive information is notified to the editing apparatus that has accessed the file about who updated the data.

  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.

(First embodiment)
[Network configuration surrounding the file reservation management device]
FIG. 1 is a diagram showing a file reservation management system 1 including a file reservation management apparatus 10 according to the first embodiment of the present invention. In the file reservation management system 1, a file reservation management apparatus 10 according to an embodiment of the present invention, a file server 20, a plurality of user terminals 30, and an IP phone 40 are connected via a network 50.

  The plurality of user terminals 30 are divided into a user terminal 30-1 requesting access to a file on the file server and another user terminal 30-2. Of the other user terminals 30-2, the user terminal 30-3 is the user terminal accessing the shared file of the file server 20, and the user terminal 30 is the user terminal of the user who is the next subscriber of the shared file. -4. In particular, when there is no need to distinguish between the user terminals 30-3 and 30-4, they are simply referred to as other user terminals 30-2. Of the user terminals 30-3 accessing the shared file of the file server 20, a user terminal (occupied user terminal) accessing the shared file for a certain period of time is referred to as a user terminal 30-3a (not shown). To do.

  The file reservation management system 1 is a system for managing access from the user terminal 30-1 to a shared file stored and managed by the file server 20 (hereinafter referred to as a file for simplification). Specifically, the file reservation management system 1 performs two processes: a process for managing file access reservations (reservation management process) and a process for notifying users who have made access reservations (notification process). . Hereinafter, the apparatus and the like constituting the file reservation management system 1 will be described separately in the reservation management process and the notification process.

  First, an apparatus and the like constituting the file reservation management system 1 in the reservation management process will be described. The user terminal 30-1 transmits a file access request to the file reservation management apparatus 10 in response to a user operation. Here, the file is a file stored and managed by the file server 20. The access request is transmitted from the file reservation management apparatus 10 to the file server 20, and the user terminal 30-1 receives the file requested to be accessed (hereinafter referred to as a request file) from the file server 20.

  When the request file is being accessed by another user terminal 30-2, the user terminal 30-1 receives the reservation status information from the file reservation management apparatus 10. The reservation status information is transmitted from the file reservation management apparatus 10 to the user terminal 30-1 so that the user of the user terminal 30-1 can make an access reservation for the requested file. Here, the reservation status information is information including reservations that have already been made for the request file, and is information that is used as a judgment material when the user makes an access reservation for the request file. The reservation status information includes, for example, the name of the user who has reserved the requested file and the time at which access to the file is desired. The user terminal 30-1 displays the received reservation status information on the screen of the user terminal 30-1.

  In addition, the user terminal 30-1 transmits reservation information for the request file input by the user operation to the file reservation management apparatus 10. Here, the reservation information is information for making a file access reservation, and includes, for example, a file name and a user name for accessing the file. The user terminal 30-1 transmits reservation information for the request file to the file reservation management apparatus 10, so that the user can make an access reservation for the request file.

  When the file reservation management apparatus 10 receives an access request to the file from the user terminal 30-1, if the requested file is being accessed from another user terminal 30-2, the reservation information is sent to the user terminal 30-1. Send. Further, the file reservation management apparatus 10 receives reservation information from the user terminal 30-1, and stores it in a reservation information DB 110 described later.

  The file server 20 stores and manages files shared by a plurality of user terminals 30. Further, the file server 20 transmits a request file in response to an access request from the user terminal 30-1, and the other user terminal 30-2 accesses while the request file is being accessed from the user terminal 30-1. Lock the file so that it cannot.

  Next, devices and the like constituting the file reservation management system 1 in the notification process will be described. The user terminal 30-1 of the user who made the access reservation receives an access permission notice from the file reservation management apparatus 10 when the reservation order comes and the access to the requested file becomes possible. In addition, the user terminal 30-3 accessing the file receives a notification from the file reservation management apparatus 10 informing the reservation waiting status of the file while accessing the file.

  The file reservation management apparatus 10 monitors the file on the file server 20 and, when unlocked by accessing the file, releases a file access permission notification to the user terminal 30-4 of the next reservation user. In addition, when the file reservation management apparatus 10 detects an occupied file accessed by the same user for a predetermined time or more, if there is a next reserved user in the occupied file, the file reservation management apparatus 10 occupies a notification notifying the reservation waiting status of the file. Transmit to the user terminal 30-3a accessing the file.

  The IP phone 40 receives an access permission notification from the file reservation management apparatus 10 when the user who made the access reservation has reached the reservation order and can access the file.

[Function block of file reservation management device]
FIG. 2 is a block diagram showing a functional configuration of the file reservation management apparatus 10 according to the first embodiment of the present invention. The file reservation management apparatus 10 includes an access request reception unit 101, an access status determination unit 102, a reservation status acquisition unit 103, a reservation status transmission unit 104, a reservation registration unit 105, a monitoring unit 106, and a user information acquisition unit. 107, a notification unit 108, an update unit 109, and a reservation information DB (reservation information storage unit) 110. Hereinafter, each functional unit will be described separately in the reservation management process and the notification process.

  First, each functional unit in the reservation management process will be described. The access request receiving unit 101 receives request file information from the user terminal 30-1. The request file information is information for accessing a file designated by a user operation in the user terminal 30-1, and is, for example, a path to a file or a file name.

  The access status determination unit 102 specifies a request file based on the information of the request file received by the access request reception unit 101, and the request file is being accessed (opened) from another terminal 30-2. Judge if there is. When the request file is being accessed from another terminal 30-2, the request file cannot be accessed from the user terminal 30-1 that made the access request. This is because the request file is locked because it is accessed from another user terminal 30-2.

  If the access status determination unit 102 determines that the request file is being accessed from another user terminal 30-2, the access status determination unit 102 transmits information on the request file to the reservation status acquisition unit 103. On the other hand, if it is determined that the request file is not being accessed, an instruction to transmit the request file specified by the information of the request file to the user terminal 30-1 that requested access is transmitted to the file server 20.

  The reservation status acquisition unit 103 acquires the reservation information for the request file from the reservation information DB 110 based on the request file information received from the access status determination unit 102. That is, reservation information of an access reservation already made for the request file is acquired. The reservation status acquisition unit 103 transmits all the acquired reservation information to the reservation status transmission unit 104 as the reservation status information of the request file.

  The reservation information DB 110 stores reservation information of access reservations for each file in a reservation information table divided for each file. FIG. 3 is an example of a reservation information table according to the first embodiment of the present invention. The reservation information table includes a user name field 111a, a waiting order field 111b, a usage time setting field 111c, a notification means field 111d, and a reservation time field 111e. In addition, the item shown here is an illustration, and may not have all and may have another item.

  The user name column 111a stores the user name of the user who made the file reservation. Note that the user name column 111a is not limited to the user name but may store information for identifying the user, for example, a user ID. In FIG. 3, initials as user names are stored.

  The waiting order column 111b stores the waiting order assigned at the time of access reservation. The waiting order is assigned in ascending order of access reservation. Further, the waiting order is incremented to 0 one by one every time file access ends. The reason why the waiting order is set to 0 is to leave information on the currently accessed user in order to notify the currently accessed user. By providing the waiting order column 111b, the user's access to the file can be set in the order of reservation. In FIG. 3, since the waiting order “1” is the user “YO”, when the access to the current file is released, the user “YO” is permitted to access the file. When a use time setting field 111c described later is set, as shown in FIG. 3, the waiting order is not stored in the waiting order field 111b.

  The usage time setting field 111c stores a user's desired access time to the file. The usage time is a time arbitrarily set by the user, and is blank when not specified by the user. Thus, the user can access the file at a desired time. In FIG. 3, the user “UA” designates the usage time, so that if the access to the file is canceled within this usage time, the user “UA” is permitted to access the file. . If access to the file is not canceled within the specified usage time, the notification specified in the notification means column 111d at the end time of the usage time, 17:00 for the user “UA” This is notified by means.

  When the user with the waiting time “1” competes with the user who has set the usage time, the user who has set the usage time may be given priority, or priorities may be given to the users in advance, and the priority order may be based on the priorities. May be determined as the next accessor. For example, when the user with the waiting order “1” and the user who has set the usage time compete with each other in the file having the reservation information in the reservation information table shown in FIG. In addition, the user “YO” with the priority “1” and the user “UA” who has set the usage time from 16:00 to 17:00 compete as the next reservation person.

  The notification means column 111d stores means for notifying the user of access permission when the order of reservation comes. Examples of the notification means include mail and IP phone. The notification means column 111d may store a mail address or IP phone number, or may store only the notification means and manage the mail address or IP phone number in a separate table. The reservation time column 111e stores the time when the user made an access reservation.

  The reservation status transmission unit 104 transmits the reservation status information of the request file received from the reservation status acquisition unit 103 to the user terminal 30-1 or the user terminal 30-2 that accessed the request file. In addition, information on a reservation registration screen that allows the user to make an access reservation for the requested file is transmitted to the user terminal 30-1 or the user terminal 30-2. The user terminal 30-1 or the user terminal 30-2 displays the reservation status information of the request file received from the reservation status transmission unit 104 and information on the reservation registration screen on an output unit such as a display of the user terminal. When the other user terminal 30-2 receives the reservation status information of the request file that has already been reserved for access from the reservation status transmission unit 104, the user of the other user terminal 30-2 has reserved the status of the file that has already been reserved for access. Can be confirmed.

  The reservation registration unit 105 receives, from the user terminal 30-1, reservation information for access reservation for the request file, which is input on the reservation registration screen displayed on the user terminal 30-1. The reservation registration unit 105 gives a waiting order to the received reservation information and stores it in the reservation information table of the corresponding request file. This reservation information includes at least user information such as a user name and notification means. When the usage time is input on the reservation registration screen, the reservation information includes the usage time. In this case, the reservation registration unit 105 does not assign a waiting order.

  In order to reduce the load on the server, the reservation registration unit 105 can also reject an access reservation when reservation information of a predetermined number or more is stored in the reservation information table. The predetermined number is the number arbitrarily determined by the administrator of the file reservation management apparatus or the like, and may be, for example, 30. By refusing access reservations of a predetermined number or more, the load on the server can be reduced. When rejecting the access reservation, a message notifying the reservation status of the request file such as “waiting for 30 or more people” may be displayed.

  In this way, even when the user cannot access the requested file, the user can make an access reservation and can ensure access to the file. In addition, when an access reservation is made, the reservation status of the requested file is presented, so that the time for accessing the file can be estimated.

  Next, each functional unit in the notification process will be described. The monitoring unit 106 monitors the access status of a file with an access reservation. Specifically, the access status of the file having the reservation information in the reservation information DB 110 is periodically checked, and among the files having the reservation information in the reservation information DB 110, the access is performed for a predetermined time or more at the same user terminal 30-3a. Check periodically whether there are any occupied files. Here, the term “periodic” refers to a certain time interval such as an interval of 5 minutes, and the predetermined time is a time arbitrarily set by an administrator of the file reservation management system 1 or the like such as 1 hour. The change in access status means that a file changes from accessing to non-accessing. In other words, the locked file is unlocked.

  In response to the change in the access status of the file, the monitoring unit 106 transmits information on the file whose access status has changed to the user information acquisition unit 107. Similarly, even if the same user terminal 30-3a detects a file being accessed for a predetermined time or longer, the file information is similarly transmitted to the user information acquisition unit 107. Here, the file information is information for specifying a file, for example, a file path or a file name.

  The user information acquisition unit 107 acquires the user name and notification means from the reservation information DB 110 based on the file information received from the monitoring unit 106. When the monitoring unit 106 detects that the access status has changed, the monitoring unit 106 acquires the user name and notification means of the next reserved user whose waiting order is “1” from the reservation information DB 110. On the other hand, when the monitoring unit 106 detects a file being accessed by the same user terminal 30-3a for a predetermined time or more, the currently-accessed user whose waiting rank is “0” and the waiting rank is “1”. The user name and notification means of each next reserved user are acquired. Furthermore, the user information acquisition unit 107 may acquire the number of reserved users based on the file information received from the monitoring unit 106.

  The notification unit 108 notifies the user with the user name received from the user information acquisition unit 107 using the notification unit received from the user information acquisition unit 107. When the monitoring unit 106 detects that the access status has changed, the notification unit received from the user information acquisition unit 107 is used to access the next reserved user of the user name received from the user information acquisition unit 107. Notify permission.

  On the other hand, when the monitoring unit 106 detects a file that is being accessed by the same user terminal 30-3a for a predetermined time or more, the user information is received using the notifying means of the accessing user received from the user information acquisition unit 107. The user who is accessing the user name received from the acquisition unit 107 is notified of the user name of the next reserved user received from the user information acquisition unit 107 together with a message that there is a waiting user.

  In any case, the number of reserved users acquired by the user information acquisition unit 107 may be notified as the waiting number. Furthermore, the waiting time may be calculated based on the number of waiting people, and the waiting time may also be notified.

  As described above, since the user can receive a notification of access permission when access to the file becomes possible, it is not necessary to frequently check the access status of the file. As a result, the operating rate of the file server 20 can be reduced, and consequently the power consumption can be reduced. In addition, the user who is accessing is notified of the user of the next reservation and the number of waiting persons, thereby prompting the user to shorten the access time. As a result, the file access waiting time can be shortened.

[Access reservation management process]
FIG. 4 is a flowchart showing processing for managing access reservation for a file according to the first embodiment of the present invention. The process starts when the access request receiving unit 101 receives information on the request file from the user terminal 30-1.

  S10: The access status determination unit 102 determines whether or not the request file is being accessed by another user terminal 30-2. Specifically, the file is specified based on the information of the request file received from the user terminal 30-1, and it is determined whether or not the file is being accessed by another user terminal 30-2. If the determination result is YES, the process moves to step S20, and if the determination result is No, the process moves to step S50.

  S20: The reservation status acquisition unit 103 acquires all the reservation information for the request file from the reservation information DB 110 as reservation status information based on the information of the request file.

  S30: The reservation status transmission unit 104 transmits to the user terminal 30-1 the reservation status information acquired in step S20 and information on a reservation registration screen that allows the user to make an access reservation for the requested file. Receiving the reservation status information and the reservation registration screen information, the user terminal 30-1 presents the reservation status information and the reservation registration screen to the user via an output means such as a display.

  S40: Reservation registration unit 105 receives the reservation information for the request file input on the reservation registration screen presented to the user in step S30 from user terminal 30-1, and stores the received reservation information in the corresponding reservation information DB 110. Store.

  S50: The access status determination unit 102 transmits an instruction to transmit the request file specified by the information of the request file to the user terminal 30-1 that requested the access.

[Notification processing]
FIG. 5 is a flowchart showing notification processing for notifying a user who made an access reservation for a file of the reservation status and the like according to the first embodiment of the present invention.
S100: The monitoring unit 106 periodically checks the access status of a file having reservation information in the reservation information DB 110, and determines whether there is a file whose access status has changed. If the determination result is YES, the process proceeds to step S110, and if the determination result is NO, the process proceeds to step S140.

S110: The user information acquisition unit 107 acquires the user name and notification means of the next reserved user whose waiting order is “1” from the reservation information DB 110 as the next reserved user information.
S120: The notification unit 108 notifies the next reservation user of access permission based on the information of the next reservation user acquired in step S110.
S130: The updating unit 109 deletes the reservation information whose waiting order is “0”, and updates the reservation information DB 110 to “0” as the waiting order of the next reservation user acquired in step S110.

S140: The monitoring unit 106 periodically checks whether there is a file being accessed by the same user terminal 30-3a for a predetermined time or longer in the file being accessed. If the determination result is YES, the process proceeds to step S150, and if the determination result is NO, the process returns to step S100.
S150: The user information acquisition unit 107 uses the user name of the accessing user whose waiting order is “0” and the notification means as the information of the accessing user, and the user name and each of the next reserved users whose waiting order is “1”. The notification means is acquired as information on the next reserved user.
S160: Based on the information on the user being accessed and the information on the next reserved user acquired in step S150, the notification unit 108 adds a message indicating that there is a user waiting for the user name of the next reserved user to the accessing user. Notice.

(Second Embodiment)
In the first embodiment, the case where the user occupies the file in units of files and the access reservation is also performed in the unit of files has been described. However, the file is divided into a plurality of areas, and the user occupies the areas in units of areas. Access reservations can also be made on an area basis. In the second embodiment, changes in that case will be described. By making an access reservation for each area, the user's access waiting time can be shortened. In the case of a file composed of a huge amount of data, it is particularly effective because locations where users want to access are often dispersed. Except for the points described below, the second embodiment is the same as the first embodiment.

  As a method of dividing a file into a plurality of areas, the conventional technique (Patent Document 1) is used. In the related art, one area is one page, but in the second embodiment, one area is not limited to one page, and a plurality of pages may be one area, or one paragraph may be one area. When the file is divided into regions, as in the prior art, the file is divided into a plurality of regions and stored in the file server 20, and the file server 20 includes a plurality of regions that hold configuration information for each region. An area management storage unit for storing an area management table composed of management blocks is required.

  In the second embodiment, all locations that are files in the description of the first embodiment are regions. In the second embodiment, the file server 20 locks the request area so that the other user terminal 30-2 cannot access the request area while the request area is being accessed from the user terminal 30-1. Lock the area management table of the area.

(Third embodiment)
In the first embodiment, there is one user who can access a file, and the case where the order of accessing a file is reserved has been described. However, a plurality of users who can access a file are described. The order in which the files are updated may be reserved. In the third embodiment, changes in that case will be described. By reserving the order in which the files are updated, the number of users who can access the file can be increased, and the waiting time for accessing the file can be eliminated. Except for the points described below, the second embodiment is the same as the first embodiment.

  FIG. 6 is a block diagram showing a functional configuration of the file reservation management apparatus 10 according to the third embodiment of the present invention. As shown in FIG. 5, the file reservation management apparatus 10 according to the third embodiment does not have the access status determination unit 102 in the first embodiment. This is for making an access reservation regardless of whether the request file is being accessed by another user terminal. In other words, in the third embodiment, the reservation information for the access reservation of the request file is always stored in the reservation information DB 110. The waiting order of the reservation information stored for each file in the reservation information DB 110 is used as the update order of the file, and a user with a lower order may update the file unless the user with a higher order updates the file. Can not. However, this is not the case when a high-ranking user cancels access to a file.

  The file reservation management apparatus 10 according to the third embodiment includes a reservation status confirmation unit 120. The reservation status confirmation unit determines whether or not an update reservation has already been made in the request file, or whether or not the user who has requested access has an update reservation rank “1”. When the update reservation is not made in the request file or the user who requests access is in the update reservation order “1”, the user who requested the access has the file of the file transmitted from the file server 20 to the user terminal 30-1. View and update rights are granted. On the other hand, when the user who has requested access is other than the update reservation order “1”, the user who has requested access is given only the viewing authority for the file transmitted from the file server 20 to the user terminal 30-1. In addition, when there is a user whose usage time is set as in the first embodiment, the user may be prioritized in usage time.

  In the third embodiment, the monitoring unit 106 monitors whether or not access to a file of a user having browsing authority and update authority has been completed. In response to the end of the access to the file of the user having the viewing authority and the update authority, the information of the file whose access is completed and the update information of the file are transmitted to the user information acquisition unit 107. The update information is information indicating whether or not the file has been updated. In addition, the monitoring unit 106 deletes the update reservation made by the user having browsing authority and update authority from the reservation information DB 110.

  The notification unit 108 uses the notification unit received from the user information acquisition unit 107 to update information received from the monitoring unit 106 via the user information acquisition unit 107 to the user having the user name received from the user information acquisition unit 107. Notification according to If the update information indicates that the file has been updated and the access has been completed, a message that the file has been updated is sent along with a notification of update permission. On the other hand, when the update information indicates that the access has been terminated without updating the file, only the update permission notification is performed. In this way, the next updater is notified of whether or not the file has been updated, thereby preventing the next updater from updating the old file.

  The user of the user terminal that has received the update permission notification from the notification unit 108 is given the browsing authority and the updating authority by reopening the file opened with the browsing authority, and can be updated.
