  Exemplary embodiments of a communication system, a server device, and a program according to the present invention will be explained below in detail with reference to the accompanying drawings. Hereinafter, a communication system that includes a server as a server device, a terminal device, and a mobile terminal as an external device, and distributes distribution information from the server to the mobile terminal will be described as an example. For example, the present invention can be applied to the case where distribution information as conference material (distributed material) used in this conference is distributed to mobile terminals possessed by each conference participant. The applicable system is not limited to this.

  FIG. 1 is a block diagram illustrating a configuration example of a communication system according to the present embodiment. As shown in FIG. 1, the communication system according to the present embodiment has a configuration in which a server 100 and mobile terminals 200a and 200b are connected via a network. Any network form such as the Internet or an intranet can be applied to the network. The network may be either wired communication or wireless communication.

  The server 100 performs transmission / reception of distribution materials, determination of whether or not to view distribution materials, and the like. The portable terminals 200a and 200b are terminals serving as a transmission source and a transmission destination of distribution materials. In the following description, it is assumed that the mobile terminal 200a is a distribution material transmission destination and the mobile terminal 200b is a distribution material transmission source. In addition, the transmission source of the distribution material is also referred to as a master (mobile terminal 200b), and the transmission destination is also referred to as a slave (mobile terminal 200a). In addition, when it is not necessary to distinguish, the mobile terminals 200a and 200b may be simply referred to as the mobile terminal 200. The number of portable terminals 200 is not limited to two. The mobile terminal 200 may be configured to have both a master function and a slave function.

  FIG. 2 is a block diagram illustrating a configuration example of the server 100. As illustrated in FIG. 2, the server 100 includes a communication unit 101, a determination unit 102, a generation unit 103, a data processing unit 104, and a storage unit 121.

  The communication unit 101 transmits / receives various information to / from an external device such as the mobile terminal 200. For example, the communication unit 101 transmits / receives distribution material data (hereinafter, also simply referred to as distribution material), position information, a threshold value that determines a range of a viewable position (viewable threshold value), a material storage location, and the like.

  The determination unit 102 refers to the position information received from the mobile terminal 200 and the browsing threshold, and determines whether the slave can browse the material. For example, the determination unit 102 determines whether or not the slave position information is included in the distributable range defined by the master position information and the viewable threshold. The determination unit 102 determines that the slave can view the material when the position information of the slave is included in the distributable range.

  The generation unit 103 generates a distribution material in a distributable format (a format that can be output by a slave), and generates access information for accessing the distribution material. For example, the generation unit 103 converts the file format so that materials in various file formats acquired from the slave can be browsed and displayed. More specifically, the generation unit 103 converts the file transmitted from the master into a general-purpose file format such as a bitmap or EMF (Enhanced Meta File) format so that the file can be displayed on the slave browser or the like. Convert to Further, the generation unit 103 generates, as access information, a URL (Uniform Resource Locator) indicating, for example, a location where the distribution material is stored. In addition, when the distribution material includes a plurality of pages, the generation unit 103 generates information for displaying the specified page.

  The data processing unit 104 controls overall processing of the server 100. For example, the data processing unit 104 instructs communication by the communication unit 101, determination of whether or not browsing is possible by the determination unit 102, and generation of materials and information by the generation unit 103.

  The storage unit 121 stores various information. For example, the storage unit 121 stores the distribution material received from the communication unit 101, the browsing threshold, the position information, the distribution material generated by the generation unit 103, and the like.

  FIG. 3 is a block diagram illustrating a configuration example of the mobile terminal 200. In FIG. 3, the mobile terminal 200b functioning as a master is described as an example, but the mobile terminal 200a functioning as a slave can also be configured to have the same function. In addition, when functioning only as a master, you may comprise so that only the function required for a master may be provided. Similarly, when functioning only as a master, it may be configured to have only a function necessary for the master.

  As illustrated in FIG. 3, the mobile terminal 200 b includes a display unit 221, a communication unit 201, a display control unit 202, a position acquisition unit 203, and a data processing unit 204.

  The display unit 221 is a medium that displays various types of information, and includes, for example, a liquid crystal display.

  The communication unit 201 transmits and receives various types of information to and from external devices such as the server 100 and a slave (mobile terminal 200a). For example, the communication unit 201 transmits / receives a distribution material, position information, a viewable threshold, a material storage location, and the like.

  The display control unit 202 controls display of information on the display unit 221. For example, the display control unit 202 displays the distribution material received from the communication unit 201 on a browser displayed on the display unit 221. Note that the program (software) for displaying information is not limited to the browser, and any program may be used as long as the distribution material can be displayed.

  The position acquisition unit 203 acquires position information of the mobile terminal 200b. For example, the position acquisition unit 203 acquires position information represented by latitude and longitude using GPS or the like. The acquisition method and expression method of position information are not limited to these. Dead reckoning, entrance / exit management by IC card, human detection by human sensor, method using distance from wireless LAN access point, method using indoor GPS (IMES: Indoor Messaging System), image captured by camera Any conventionally used method such as a processing method, a method using active RFID, and a method using visible light communication can be applied.

  The data processing unit 204 controls the overall processing of the mobile terminal 200b. For example, the data processing unit 204 instructs communication by the communication unit 201, display by the display control unit 202, and position acquisition by the position acquisition unit 203.

  Next, the operation flow of the communication system according to the embodiment as described above will be described. FIG. 4 is a sequence diagram schematically illustrating an example of an operation flow of the communication system according to the embodiment.

  The master transmits the distribution material, the master position information, and the viewable threshold value to the server 100 (step S101). The master position information is position information acquired by the master position acquisition unit 203. The server 100 stores the received distribution material, master position information, and viewable threshold in the storage unit 121 (step S102).

  The server 100 generates a URL for browsing the distribution material (material browsing URL) and transmits it to the master (step S103). The master transmits a material browsing URL to the slave using infrared rays, NFC (Near Field Communication), mail, or the like (step S104). If infrared rays, NFC, or the like is used, the document browsing URL can be transmitted only to the slave that is actually close to the master. When mail is used, for example, a method of acquiring a slave's mail address in advance using NFC or the like and transmitting a material browsing URL to the acquired address can be applied.

  The slave accesses the document browsing URL received from the master (step S105). At this time, the slave transmits slave position information to the server 100 (step S106). The slave position information is position information acquired by the slave position acquisition unit 203.

  The server 100 determines whether or not the slave is within a viewable range (step S107). For example, the server 100 determines whether the slave position information is within the browseable threshold of the master position information (step S107). If it is within the browseable range (step S107: Yes), the server 100 transmits the distribution material to the slave (step S108). The slave displays the received distribution material (step S109). The slave returns to step S106 after a certain time and repeats the process.

  If it is not within the viewable range (step S107: No), the server 100 ends the transmission of the distribution material (step S110). In response to the notification of the end of transmission from the server 100, the slave ends the display of the distribution material (step S111).

  Hereinafter, the sequence of FIG. 4 will be described in more detail. FIG. 5 is a sequence diagram illustrating an example of processing from the start of the system to acquisition of a material browsing URL.

  The master data processing unit 204 instructs the communication unit 201 to access the material distribution URL (step S201). For example, when the user designates access to the material distribution URL using a browser or the like, the data processing unit 204 instructs access to the designated material distribution URL.

  The material distribution URL is information indicating a resource such as a web page defined for distributing the material. For example, a URL of a homepage defined as a material distribution route is used as the material distribution URL. By making it possible to specify the URL for material distribution, for example, it is possible to specify the URL under which the material is distributed. For example, when there are a plurality of servers 100, it is possible to specify which server 100 is used. When the material distribution URL is fixed (when the server 100 is determined in advance), processing such as access to the material distribution URL may be omitted.

  The communication unit 201 accesses the document distribution URL according to the instruction (step S202). The server 100 transmits the contents of the material distribution URL to the master (step S203).

  The master communication unit 201 acquires the contents of the material distribution URL (step S204). The master data processing unit 204 instructs the display control unit 202 to display the contents of the material distribution URL (step S205). In response to the instruction, the display control unit 202 displays the contents of the material distribution URL (step S206).

  FIG. 6 is a diagram showing an example of the contents (setting screen) of the URL for material distribution. In the example of FIG. 6, an example is shown in which a distribution material, a viewable threshold value, master position information, and a position information confirmation cycle are displayed as the content of the material distribution URL described at the top.

  The distribution material is a column for specifying the distribution material. For example, the user inputs the file path of the distribution material in the distribution material column. The file format is a format that can be distributed by the server 100 (for example, pdf, jpg, bmp, png, etc.).

  The viewable threshold value is a column for setting a threshold value for determining a distributable range with reference to the master position information. FIG. 6 shows an example in which a latitude difference and a longitude difference are set as browseable threshold values. dd, mm, ss and sss represent degrees, minutes, seconds and milliseconds, respectively. In this case, the range of the position where the difference with respect to the latitude and longitude of the master position information is equal to or less than the values specified by the longitude difference and the latitude difference is the distributable range.

  Note that the delivery range designation method is not limited to this. Instead of using the threshold value, the distribution possible range itself may be designated. Instead of using the master position information as a reference, a reference position may be designated. The distributable range may be specified by specifying the radius (diameter) of a circle centered on the specified reference position. When the floor (floor) and room to which the material is distributed are managed by the map information, the information specifying the floor and the room may be designated. Moreover, you may comprise so that it can designate using other scales, such as a meter, instead of specifying with scales, such as a latitude and a longitude.

  The master position information is a field for inputting the position information of the master. The position information may be automatically input by pressing a “position information acquisition” button. It is also possible to manually input position information.

  The position information confirmation cycle is a column for setting a cycle time for updating the slave position information. The server 100 requests the slave to transmit position information every time set in this field.

  When the user presses the “Send” button, the set information is sent to the server 100. When the user presses the “Cancel” button, the system ends.

  FIG. 7 is a diagram illustrating an example of a setting screen displayed after the “Send” button in FIG. 6 is pressed. As shown in FIG. 7, in this case, the document browsing URL generated by the server 100 is displayed.

  Returning to FIG. The user sets (inputs) each information on the displayed setting screen as shown in FIG. In response to the input from the user, the master display control unit 202 performs setting of the distribution material file path (step S207), setting of the browsing threshold (step S208), and setting of the position information (step S209). Display the setting screen.

  The master data processing unit 204 instructs the position acquisition unit 203 to acquire position information (step S210). The position acquisition unit 203 acquires current position information (step S211). The data processing unit 204 instructs the communication unit 201 to transmit the information set by the display control unit 202 (step S212). The communication unit 201 transmits the setting content to the server 100 in response to the instruction (step S213).

  The server 100 generates a document browsing URL according to the setting contents (details will be described later), and transmits the generated document browsing URL to the master (step S214).

  The master communication unit 201 acquires a document browsing URL (step S215). The data processing unit 204 instructs the display control unit 202 to display the document browsing URL (step S216). The display control unit 202 displays the document browsing URL (step S217). FIG. 7 shows an example of the setting screen displayed as a result of step S217.

  FIG. 8 is a sequence diagram showing an example of processing from the URL for browsing the document to the browsing of the document by the slave.

  The slave communication unit 201 designates the document browsing URL and transmits an access request to the distribution document (step S301). The slave data processing unit 204 instructs the position acquisition unit 203 to acquire position information (step S302). The slave position acquisition unit 203 acquires position information (step S303). The slave communication unit 201 transmits the acquired position information (slave position information) to the server 100 (step S304).

  The server 100 acquires slave position information (step S305). The server 100 determines whether or not the slave is within a viewable range (step S306). If it exists within the range (step S306: Yes), the server 100 transmits the material to the slave (step S307).

  The slave communication unit 201 acquires the material (step S308). The slave data processing unit 204 instructs the display control unit 202 to display the material (step S309). The slave display control unit 202 displays the material according to the instruction (step S310). After a predetermined time, the slave returns to step S302 and repeats the process.

  If it is determined in step S306 that it does not exist within the range (step S306: No), the server 100 stops the material transmission (step S311). For example, the server 100 transmits material transmission stop information indicating that the material transmission is stopped to the slave.

  The slave communication unit 201 acquires material transmission stop information (step S312). The slave data processing unit 204 instructs the display control unit 202 to end the document display (step S313). The slave display control unit 202 ends the display of the material according to the instruction (step S314).

  FIG. 9 is a sequence diagram illustrating an example of browsing permission / inhibition determination and material transmission processing performed by the server 100. It is assumed that master position information and a browseable threshold are set in the server 100.

  The communication unit 101 of the server 100 acquires slave position information from the slave (step S401). The data processing unit 104 of the server 100 instructs the determination unit 102 to determine whether browsing is possible (step S402). The determination unit 102 of the server 100 determines whether or not browsing is possible based on the master position information, the slave position information, and the browsing threshold (step S403).

  If it is determined that browsing is possible, the process proceeds to step S404. If it is determined that browsing is not possible, the process proceeds to step S407.

  In step S404, the data processing unit 104 of the server 100 instructs the generation unit 103 to transmit the distribution material (step S404). In response to this instruction, the generation unit 103 of the server 100 generates contents to be displayed from the distribution material (step S405). For example, the generation unit 103 generates display contents including a designated page of the distribution material (for example, the first page in the first case). The communication unit 101 of the server 100 transmits the display content generated to the slave (step S406). Thereafter, the communication unit 101 acquires the slave position information again after the time set in the position information confirmation cycle has elapsed. When the acquisition is unsuccessful, the data processing unit 104 instructs the material transmission to be stopped.

  In step S407, the data processing unit 104 of the server 100 instructs the communication unit 101 to stop sending the distribution material (step S407). The communication unit 101 of the server 100 stops transmitting the material to the slave according to the instruction (step S408).

  Next, an example of determining whether browsing is possible by the determination unit 102 of the server 100 will be described. FIG. 10 is a diagram illustrating an example of each piece of information when it is determined that browsing is possible. The server 100 calculates a viewable range from the master position information and the viewable threshold value. In the example of FIG. 10, when the longitude of the master position information is “35.44.33.150” and the viewable threshold is “0.0.0.10”, the viewable range is “35.44”. .33.140 to 35.44.33.160 "are calculated. Since the slave position information is within the browseable range for both latitude and longitude, it is determined that browsing is possible.

  FIG. 11 is a diagram illustrating an example of each piece of information when it is determined that browsing is impossible. In the case of FIG. 11, the longitude of the slave position information is “35.44.33.161”, which is out of the viewable range, so it is determined that viewing is not possible.

  FIG. 12 is a sequence diagram illustrating an example of a page control process performed by the server 100. When the distribution material includes a plurality of pages, the slave can operate the browsing information by page control (page advance, page return, enlargement / reduction, etc.) when browsing the material. FIG. 12 shows an example of processing when transition to the next page is designated.

  When the user presses the next page display button on the browser, the slave receives the press of the next page display button (step S501). The slave transmits to the server 100 a next page display instruction indicating that the next page display button has been accepted.

  The communication unit 101 of the server 100 receives the next page display instruction (step S502). The data processing unit 104 of the server 100 instructs the generation unit 103 to generate the next page (step S503). The generation unit 103 of the server 100 generates display content for the next page (step S504). The data processing unit 104 of the server 100 instructs the communication unit 101 to transmit the generated display content (step S505). The communication unit 101 of the server 100 transmits the display content generated to the slave in response to the instruction (step S506). The slave displays the acquired display content (next page) (step S507).

  FIG. 13 is a diagram illustrating an example of a display screen displayed by the slave display control unit 202. The slave display control unit 202 displays the material obtained by designating the material browsing URL via the browser. The display control unit 202 can perform page control (page advance, page return, enlargement / reduction) by pressing a button arranged on the browser.

  As described above, in the communication system of the present embodiment, the server 100 can provide materials based on the result of comparing the position information of the master and the slave. As a result, it is possible to distribute the material to an unexpected participant without having to register in advance. Further, since the material is distributed only to slaves within the distributable range, it is possible to reduce the possibility of unauthorized access to the material and improve the security.
