Description

  The present invention relates to a module license management method executed by an information processing apparatus used in a client server type system.

  2. Description of the Related Art Conventionally, in a client server system including a client terminal and a server, it is known that a client terminal downloads a client application program from the server and realizes an automatic installation function of the downloaded program. Also in the system, a mode in which the client terminal downloads the application program from the server is conceivable.

  Such an automatic installation function is realized by an OS (Operating System) existing in the client terminal and the server. In addition, the client application program installed in the client terminal is controlled to start based on start permission information (license information) managed by the server.

  This license information is generally indicated by the total number of client terminals permitted to start the client application program. In the conventional management of license information, the client application program downloaded to each client terminal is included in the license information. Based on this, each client terminal accesses the server license management unit of the server, and the license management of the client application program is performed by limiting the number of licenses so as not to exceed the number of licenses on the server side.

  However, in the system as described above, since the client application program is automatically downloaded by the OS when the program is requested to start, the number of client terminals to which the client application program has been downloaded is determined by the application program. However, there is a problem that access from any client terminal is possible unless the server is accessed at the same time.

  To solve these problems, client application programs can be started only from fixed client terminals for the number of licenses allowed in a client server system that downloads and installs client application programs from the server to client terminals. A client license management system is disclosed (for example, Patent Document 1).

JP 2002-23882 A

  According to the technique disclosed in Patent Document 1, the number of remaining licenses in the server is confirmed. If the number of remaining licenses is 1 or more, the number of remaining licenses in the server license management unit is subtracted by 1, and the client license It is possible to control the client application program not to be activated by the client license management unit if the license is registered in the management unit and the client application program is activated and the remaining license number is zero.

  By the way, when a client server type system is used, a module different from the client application program may be required. For example, a TV conference system or a web conference system may require a module (for example, MPEG-4) or the like in order to display the other party's state as a still image or a moving image.

  At this time, each of the client application and the module is installed in the client terminal. This module is not original for client applications, and is often general purpose for using other applications on client terminals. For this reason, the user may download the client application and the modules required for using the application through different routes. For the system administrator, whichever number of users of the system It was difficult for only users to download modules via this system.

  Therefore, the present invention provides a mechanism capable of grasping how many users of a system have acquired a module via the system and appropriately managing the number of licenses from there. The purpose is to do.

That is, according to the present invention, a client terminal, a module required to execute a client module distributed to the client terminal, and an information processing apparatus that stores and manages license information of the module can be connected via a network. A first information processing apparatus that stores the number of modules distributed from the information processing apparatus to the client terminal and identification information of the client terminal that is the transmission destination of the module storage means, said modules being distributed from the information processing apparatus or the client terminal carrying the module that was distributed not through the information processing apparatus, available to the module in the information processing system User notification to notify the client terminal A user notification receiving means for receiving from the client terminal,
By using the user notification received by the user notification receiving means, the apparatus has second storage means for storing identification information of the client terminal that uses the information processing system, and is stored in the first storage means. By matching the client terminals stored in the second storage means, the client terminals are matched with each other from all client terminals using the information processing system via the information processing system. It is characterized by calculating how many client terminals have the module installed .
Furthermore, the information processing apparatus of the invention, an instruction receiving means for receiving the uninstall instructions of the client terminal from the module, when said accepting the uninstallation instruction of the module from the client terminal by said instruction accepting means, before Symbol first A determination unit that determines whether the client terminal has acquired the module from the information processing apparatus by using the identification information of the client terminal stored in one storage unit; and When it is determined that the module has been acquired from the information processing apparatus, the client terminal includes first notification means for notifying that the module can be uninstalled.
Furthermore, the information processing apparatus according to the invention is such that when the determination unit determines that the client terminal has not acquired the module from the information processing apparatus, the module cannot be uninstalled from the client terminal. It is characterized by comprising a second notification means for notifying.
Furthermore, the information processing apparatus according to the present invention includes the number of modules provided to the client terminal stored in the first storage unit and the identification information of the client terminal that is a transmission destination of the module by communication between the plurality of information processing apparatuses. Synchronizing means for synchronizing is provided.

  According to the present invention, there is provided a mechanism capable of grasping how many users of a system have acquired a module via the system and appropriately managing the number of licenses therefrom. It becomes possible to do.

<First embodiment>
Hereinafter, an embodiment of module license management in a web conference system according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a system configuration diagram showing an example of a web conference system including an information processing apparatus according to the present invention. The client terminal 110 suitable for the information processing apparatus of the present invention is, for example, a personal computer, has a network communication function, and via the LAN 105 (local area network), the web conference server 101, the listening server 102, and the recording server 103. And data communication is possible.

  The client terminal 110 is a personal computer operated by a user who uses the web conference system, and is installed with a web browser for accessing the web conference server 101, the listening server 102, and the recording server 103, and a dedicated module. Yes. Note that this dedicated module is an ActiveX component that is downloaded from the web conference server 101 via a web browser, for example. Note that a web camera (not shown) is connected when transmitting a moving image of itself in a web conference, and a microphone (not shown) is connected when transmitting audio. Also, a speaker (not shown) is connected to view the other party's voice.

  The web conference server 101 is a server for realizing a web conference using a web browser. By accessing the web conference server 101, the client terminal 110 can acquire a web conference screen (interface) and conduct a web conference.

  FIG. 2 is a diagram illustrating a hardware configuration of the web conference server 101, the listening server 102, the recording server 103, and the client terminal 110.

  As shown in FIG. 2, in the web conference server 101, the listening server 102, the recording server 103, and the client terminal 110, a CPU (Central Processing Unit) 201, a RAM (Random Access Memory) 202, a ROM via a system bus 204 (Read Only Memory) 203, an input controller 205, a video controller 206, a memory controller 207, and a communication I / F controller 208 are connected.

The CPU 201 comprehensively controls each device and controller connected to the system bus 204.
The ROM 203 or the external memory 211 that is a storage device can be read by a computer (BIOS) or OS (Operating System) that is a control program executed by the CPU 201, or can be read by a computer to realize this data destination designation method. It holds programs and various necessary data (including data tables).

  The RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 203 or the external memory 211 as a storage device to the RAM 202 and executing the loaded program.

  The input controller 205 controls input from the keyboard 209. The video controller 206 controls display output to a CRT 210 that is an example of a display unit. The memory controller 207 controls reading of information stored in the external memory 211 and writing of information to the external memory 211.

  The communication I / F controller 208 is connected to a communication line to control data transmission / reception. In the case of a client terminal, the communication I / F controller 208 controls transmission / reception of data via the LAN 105, while in the case of the web conference server 101, the listening server 102, and the recording server 103, the communication I / F controller 208 Similarly, control of data transmission / reception via the LAN 105 and control of data transmission / reception via the public line 106 are also performed.

  It is assumed that the external memory 211 of the web conference server 101, the listening server 102, and the recording server 103 stores a download number log file of FIG. It is assumed that a computer-readable program for executing a flowchart described in the drawings described later is also stored in the external memory 211. The external memory 211 of the web conference server 101 stores a user database (not shown) that uses the web conference system.

  The external memory 211 is a medium for permanently storing information, and the form is not limited to a storage device such as a hard disk. For example, a medium such as SSD (Solid State Drive) may be used.

  Processing in the embodiment of the present invention will be described with reference to FIG. This flowchart is realized by the CPU 201 executing the program of the present invention stored in the external memory 211 using the RAM 202 of the client terminal or the web conference server as a work area.

  First, in step S401, the client terminal 110 receives a user operation, transmits a web conference start instruction to the web conference server 101, and makes a web conference screen acquisition request. The web conference start instruction is transmitted to the web conference server by accepting a press of a “web conference start” button displayed on the initial menu screen (not shown) of the web conference. The web conference screen acquisition request method transmits an HTTP request, which is a request based on HTTP, to the server.

  In step S402, when the web conference server 101 receives a web conference start instruction (HTTP request) from the client terminal 110, the web conference server 101 acquires a request type, a requested file, other parameters, and the like from the received HTTP request, and is necessary. After performing this process, a response is transmitted to the client terminal 110. As response information, a web conference screen to be displayed on the client terminal 110 is transmitted (step S403). In step S404, the client terminal 110 receives the web conference screen and displays it on the display unit (display 210).

  Next, when starting a web conference, the client terminal 110 checks whether or not a client module necessary for using the web conference system is installed. If the client module is not installed (NO in step S404-2), the process proceeds to step S405. If the client module is already installed (YES in step S404-2), the process proceeds to step S409 without performing the processes in steps S405 to S408.

  In step S <b> 405, when it is determined in step S <b> 404-2 that the client module is not installed, the client terminal 110 transmits a client module acquisition request to the web conference server 101.

  Upon receiving the client module acquisition request, the web conference server 101 transmits the client module in step S407. In step S408, the client terminal 110 downloads the client module.

  In step S <b> 409, the client terminal 110 transmits a license information acquisition request to the web conference server 101. At this timing, the client terminal 110 makes an inquiry to obtain license information of the web conference system supported by the web conference server 101. In executing the web conference system, the web conference server 101 has, for example, licenses for moving images (for example, MPEG-4) and still images (for example, JPEG 2000). Depending on whether one of these licenses is held, in the subsequent steps, it is determined whether or not to install the installer of the moving image playback module (for example, MPEG-4) on the client terminal. That is, the license information refers to a module issuance authority for executing the web conference system held by the web conference server 101.

  In step S410, when the web conference server 101 receives the license information acquisition request, the web conference server 101 confirms the license information of the playback module for playback of the web conference system held by the apparatus, and in step S411, there is a request. License information is issued to the client terminal 110. In step S412, the client terminal 110 acquires license information.

  In step S413, the playback module held by the web conference server 101 is confirmed. Specifically, it is confirmed whether or not the license information held by the web conference server 101 is a video playback module (for example, MPEG-4). If the video playback module is available, the process proceeds to step S414. . If the web conference server 101 cannot issue the moving image playback module (has no license information), the process according to this sequence chart is terminated.

  In step S414, it is confirmed whether or not a moving image playback module is already installed in the client terminal 110. If installed, the process proceeds to step S420 to display a video and start a web conference. The already installed situation refers to the case where the client terminal 110 has been previously used in the web conference system of the present invention and is installed from the web conference server 101. In addition, when using other systems, the same moving image playback module used in the present embodiment may already be installed in the client terminal 110. If the video playback module is not installed, the process advances to step S415 to transmit a video playback module installer acquisition request to the web conference server 101.

  In step S <b> 416, when the web conference server 101 receives the moving image playback module installer acquisition request from the client terminal 110, the web conference server 101 transmits the moving image playback module installer to the client terminal 110 in step S <b> 417. In step S419, the web conference server 101 generates a download number log file in order to record the number of issued animation playback module installers. Since the web conference server 101 has an upper limit on the number of installers issued based on its own license information, the web conference server 101 issues an unlimited number of installers unless the number of installers issued is stored in the client terminal 110. Will be possible. In order to prevent this situation, the number downloaded by the client terminal 110 needs to be recorded. The download number log file will be described in detail with reference to FIG.

  In step S418, the client terminal 110 downloads an installer for the moving image playback module. After the download, when the video playback module is installed in the client terminal, in step S420, the client terminal 110 transmits a user notification to use the web conference system.

  In step S419, the web conference server 101 generates a log (download information) of the client terminal 110 that has downloaded the video playback module. The download information generated here includes the information shown in FIG.

  In step S421, when the use notification of the web conference system is received from the client terminal 110, the number-of-users log file is updated.

  FIG. 3 is a diagram showing a data table configuration of a download number log file for recording the number of client terminals 110 that have issued the installer of the video playback module by the web conference server 101 in step S419.

  301 is information for uniquely identifying the client terminal. For example, as the client terminal information, a personal computer serial number, a MAC address, a management number, and the like are recorded in this item.

  Reference numeral 302 denotes registration date and time information indicating the date and time when the module is installed. The date and time when the web conference server 101 transmits the module installer to the client terminal 110 is recorded in this item.

  Reference numeral 303 denotes information indicating the update date and time. For the client terminal 110 that downloads the video playback module for the first time, the same date and time value as the registration date and time information is recorded. For the client terminal 110 that has already registered once, the date and time when this module was acquired is displayed in this item. To be recorded.

  In addition, by recording the license issuance number 300, the number of download log files is made to coincide with the number of moving image playback modules issued.

  By recording the download information in FIG. 3, the web conference server 101 can easily confirm to which client terminal 110 the license of the video playback module has been granted.

FIG. 5 is a block diagram showing a functional configuration of the web conference server 101 used in the web conference system of the present invention.
The web conference server 101 includes the user management unit 501, the room management unit 502, the reservation management unit 503, and the system management unit 504 of the present embodiment as a web conference system reservation system 500.
The video conference unit 510 includes a download number control unit 512, a user number control unit 513, an entrance / exit control unit 514, and a media control unit 515 as a response control unit 511, and a media data distribution control unit 520. There is.

<Second Example>
In the first embodiment, the web conference server 101 transmits the client application and the video playback module to the client terminal 110, and stores the number of downloaded modules and the identification number of the downloaded client terminal 110. In the second embodiment, when a special server such as the listening server 102 and the recording server 103 that is different from the original function of the web conference server 101 is incorporated in the configuration of the web conference system, or the web conference A case where the web conference system in the present embodiment is realized by using a plurality of servers 101 will be described.

  Similar to the web conference server 101, the listening server 102 and the recording server 103 issue a client application acquisition request from the client terminal 110 and issue a client application. (When the video playback module is not installed in the terminal 110).

  At this time, each of the servers 101 to 103 stores the identification information (301 in FIG. 3) of the client terminal 110 that received the access, and generates a download number log file. In this case, since the number of downloaded modules and the identification information of the client terminal are stored in each server, it is necessary to synchronize the information stored in the server at an appropriate timing.

  For example, when the client terminal 100 accesses the web conference server 101 to participate in the web conference, installs the video playback module, and then accesses the recording server 103, the recording server 103 identifies the identification information of the client terminal 110. Is not stored, it cannot be determined whether the client terminal has installed the video playback module via the web conference system or the external system. In addition, if there is an upper limit on the number of module downloads as a web conferencing system, the total number of the system cannot be grasped even if the number of downloads is managed only on each server. There is also a risk of it.

  Therefore, each server that constitutes the web conference system stores a download count log file of the client terminal, and periodically has a high specification such as a processing speed and the parent server of the system. The download number log file and the client terminal identification information are transmitted to a server or the like to synchronize the information. Alternatively, it is desirable that each server transmits each other's information, and all the servers have the same information.

  As described above, in the second embodiment, the number of downloads of the client terminal 110 and the identification information of the downloaded client terminal 110 are stored in one server or all the servers, so that the client terminal 110 is used differently from normal use. Even when the web conferencing system is accessed by the method, it is possible to grasp whether the video playback module is installed via the web conferencing system or from the outside.

  In a normal client-server system, the video playback module installed in the client terminal 110 is not a dedicated video playback module used only for the system (the web conference system in the present embodiment). However, a standard module that can be applied when other applications are used is assumed (for example, MPEG-4). Therefore, when the client application (or client module) is uninstalled from the client terminal, the video playback module cannot be uninstalled from all the client terminals 110 (the video playback module is changed to another client application). Because it is likely to be applied).

  However, in the present embodiment, at the time of downloading, the web terminal transmits the client terminal identification information (301 in FIG. 3) and the user notification from the client terminal 110 (receives the client terminal identification information in step S421). Since storage management is performed by the server 101, among actual users, if the user has acquired the module via the web conference system, the module is also uninstalled at the same time when the client application is uninstalled. It is possible.

  In the present embodiment, when the client application 110 receives an instruction to uninstall the client application, the client application 110 uninstalls the client application and the video playback module, and identification information of the client terminal (301 in FIG. 3). Send. When the web conference server 101 receives an uninstall instruction and client terminal information from the client terminal 110 (corresponding to an instruction accepting unit), the web conference server 101 determines whether or not a module installed in the client terminal should be uninstalled at the same time. When installing the video playback module, the terminal identification information 301 of the client terminal can be acquired from the download count log file (FIG. 3) stored in the web conference server 101. Therefore, when uninstalling the client module (client application) from the client terminal 110, if the terminal identification information 301 of the client terminal 110 is confirmed, it is determined whether or not the video playback module has been downloaded when using the web conference system. It becomes possible to judge.

  When it is determined that the downloaded video playback module is used when using the web conference system, the client terminal 110 can be notified that the video playback module can be uninstalled. In addition, if the video playback module is not downloaded when the web conference system is used, the module is not uninstalled at the same time when the client application is uninstalled.

  Furthermore, in the embodiment of the web conference system according to the present invention, a user notification (specifically, terminal identification information) is transmitted to use the web conference system (step S421). The web conference server 101 matches the terminal identification information (301) stored in each of the user log file and the download log file of the web conference system, so that all users can pass through the web conference system. Thus, it is possible to calculate how many users (client terminals 110) have installed the moving image reproduction module (corresponding to the calculating means of the present invention). Thereby, it is assumed that it is used for the user marketing tool of this web conference system.

  Furthermore, as another use case, among the client terminals 110 (information of the client terminals 110 that can be acquired from the user number log file) used in the web conference system, the client that downloaded the video playback module from the web conference system If the royalty of royalty payments varies depending on the number of downloads by obtaining the exact number of terminals 110, this web conferencing system is not calculated based on the number of users of the video playback module. It is possible to adopt a method for calculating a payment fee based on the number of downloads from the module, which can be a means for realizing royalty payment at an appropriate amount for a module distributor.

  As described above, according to the present invention, it is possible to grasp how many users of a system have acquired a module via the system, and appropriately manage the number of licenses therefrom. Can be provided.

Specifically, according to the present invention, a client terminal, a module required to execute a client module distributed to the client terminal, and an information processing apparatus that stores and manages license information of the module are connected via a network.
