  The communication unit 101 is a part that performs communication connection with the management server 300 via the network NW by wireless communication.

  The search unit 102 is a part that searches the management server 300 for one or more mobile devices 200 that are other communication devices via the communication unit 101. Specifically, in order to search for one or a plurality of mobile devices 200 located within a predetermined radius of the mobile device 100 that is the own device, the communication unit 101 is used to search for the telephone number and identification ID (for example, the mobile device 100). MAC address) is transmitted to the management server 300, and as a response, the telephone number and identification ID of one or a plurality of mobile devices 200 existing within a predetermined radius of the mobile device 100 stored in the management server 300 are received.

  The acquisition unit 103 is a part that acquires the telephone numbers and identification IDs of one or more mobile devices 200 received by the search unit 102. The acquisition unit 103 outputs the acquired telephone number and identification ID to the determination unit 104.

  The determination unit 104 is a part that determines whether or not the telephone number of one or more mobile devices 200 acquired by the acquisition unit 103 is included in the phone book data stored in the phone book data storage unit 105. . When determining that the telephone number is included in the telephone book data, the determining unit 104 stores the telephone number and identification ID of one or more mobile devices 200 acquired by the acquiring unit 103 in the permission table 106. Since the phone number registered in the phone book data is the phone number of an acquaintance or the like and not the phone number of a stranger, it can be determined that access to the shared folder may be permitted.

  The phone book data storage unit 105 is a part that stores a telephone number and its name in association with each other, and is information used for inputting a destination when making a call.

  The permission table 106 is a part that stores the identification ID of one or a plurality of mobile devices 200 that permit access to the shared folder and the folder ID of the shared folder to be accessed based on the result determined by the determination unit 104. is there. FIG. 4 is an explanatory diagram showing a specific example of the permission table 106. As shown in FIG. 4, the telephone number, identification ID, and time stored in the permission table 106 indicating one or more permitted mobile devices 200 are associated with the folder ID that uniquely identifies the folder. It is stored in association. The time here is the time when the search process is performed on the management server 300, and the search unit 102 repeatedly performs the search process for one or a plurality of mobile devices 200 at predetermined intervals using this time. Can do.

  When the determination unit 104 determines that one or more mobile devices 200 that may be accessed exist, the generation unit 107 generates a shared folder that the mobile device 200 can access. is there. The generation unit 107 assigns a folder ID to a shared folder to generate a shared folder, and stores the folder ID in the permission table 106 in association with the identification ID of one or more mobile devices 200 that are permitted to access. Let

  The folder storage unit 108 is a part that stores a shared folder. The folder storage unit 108 can store a plurality of shared folders separately for each folder ID. Further, the shared folder can hold a file and further hold another lower folder. The shared folder stored in the folder storage unit 108 may be generated by the generation unit 107 described above or may be generated in advance.

  When one mobile device 200 makes an access request (including the identification ID of the one mobile device 200) via the communication unit 101, the permission unit 109 stores the identification ID of the one mobile device 200 in the permission table 106. It is a part which judges whether it corresponds with the identification ID memorize | stored in this, and judges whether access is possible. If access is permitted here, access to the shared folder stored in the folder storage unit 108 is permitted. That is, the permission unit 109 can transmit a file or a lower folder held in the shared folder so that the mobile device 200 can view the file or the lower folder. If access from one mobile device 200 is rejected, access to the shared folder in the folder storage unit 108 is rejected, and a message to that effect is transmitted to the one mobile device 200.

  The folder storage unit 108 may store a plurality of shared folders. In this case, the permission unit 109 is associated with the identification ID of one mobile device 200 in the permission table 106. Access is permitted to the shared folder having the folder ID.

  In addition, the permission unit 109 allows access to the folder ID associated with the identification ID of one or more mobile devices 200 stored in the permission table 106. However, the present invention is not limited to this. Instead, an order may be added to the shared folders, and the shared folder to which access is permitted may be changed according to the communication partner. For example, the order may be determined in descending order of the communication amount with respect to the mobile device 100.

  The connection condition setting unit 111 is a part that accepts setting of access conditions for the shared folder, and accepts the setting input by a user operation. Further, a scheduler provided in the mobile device 100 may be used as the connection condition setting unit 111, and the permission unit 109 may perform access permission based on schedule information by the scheduler. That is, by using the action schedule (when and where it is located) determined by the schedule information, a user (mobile device 200) having the same action schedule is identified, and an access request from the user (mobile device 200) is issued. You may make it permit. The identification method, such as whether the schedule information is the same, stores the identification ID of the mobile device 100 and the schedule information on the management server 300 side, and the same schedule information according to the search request from the mobile device 100 A mobile device 200 having a Further, in the schedule information of the mobile device 100, a telephone number or identification ID for specifying a meeting partner, a meeting partner, etc. may be described, and that information may be used. Here, the scheduler is an application that creates schedule information describing time and place.

  The connection condition storage unit 112 is a part that stores settings accepted by the connection condition setting unit 111. For example, the connection conditions include a connectable time zone or schedule information.

  The deletion unit 113 is a part that deletes the shared folder stored in the folder storage unit 108 in accordance with a predetermined condition, and periodically searches the search unit 102 for the presence or absence of one or more other mobile devices 200. When one or a plurality of other mobile devices 200 are all gone, the shared folder indicated by the folder ID associated with the other mobile device 200 is deleted. The deletion unit 113 can also operate in conjunction with the scheduler. For example, based on the conference end time determined by the scheduler, the deletion unit 113 can be used to share a shared folder for attendees of the conference and access permission thereof. The folder ID and identification ID in the permission table 106 may be deleted.

  The positioning unit 114 is a part that measures the position of the mobile device 100 at predetermined intervals. The measured information is transmitted to the management server 300 via the communication unit 101 and stored in the position information table.

  With such a configuration, the mobile device 100 that has received an access request from the mobile device 200 can permit the access request. Here, the access request from the mobile device 200 is made via the communication unit 101 here, but the access request is not limited to this. For example, the mobile device 200 and the peer to the mobile device 200 are connected by short-range wireless communication such as Bluetooth. An access request may be accepted by communication connection with Peer.

  A process of creating a shared folder for the mobile device 100 configured as described above will be described. FIG. 5 is a flowchart showing a process for creating a shared folder. When a search operation is performed by the user, the search unit 102 transmits a search request for one or a plurality of mobile devices 200 (S101). Here, the search unit 102 transmits a search request including the identification ID and telephone number of the mobile device 100 to the management server 300.

  In the management server 300, the location information of the mobile device 100 is extracted based on the transmitted identification ID or telephone number of the mobile device 100, and one or more movements within a predetermined range based on the location information of the mobile device 100 The telephone number and identification ID indicating the machine 200 are extracted, and the telephone number and identification ID are returned. In the mobile device 100, the search unit 102 receives the confirmation result including the telephone number and identification ID of the mobile device 200 from the management server 300 via the communication unit 101 (S102).

  Then, the determination unit 104 determines whether or not the received telephone numbers of the one or more mobile devices 200 are the telephone numbers stored in the telephone directory data storage unit 105 (S103). Here, if it is determined that the telephone number is stored in the telephone directory data storage unit 105, one or a plurality of mobile devices that are subject to access permission together with a mobile device list indicating one or a plurality of mobile devices 200. A screen for selecting 200 is displayed on a display unit (not shown) (S104).

  Here, when an operation unit (not shown) is operated by the user and a mobile device 200 to be permitted to access is selected (S105: YES), one or a plurality of mobile devices 200 that permit connection by the determination unit 104. Are stored in the permission table 106 (S106). These telephone numbers and identification IDs are stored, and a shared folder is generated and stored in the folder storage unit 108 by the generation unit 107 (S107). A folder ID that can uniquely identify the shared folder generated together with the storage process of the shared folder is stored in association with the identification ID of the selected mobile device 200 in the permission table 106.

  In this way, the shared folder that can be accessed by the mobile device 200 within a predetermined range from the mobile device 100 that is its own device is stored in the folder storage unit 108. Here, the mobile devices 200 that are permitted to access using the phone book data are limited so that an unspecified number of people are not accessed.

  Next, access permission processing for the shared folder generated by the mobile device 200 in the mobile device 100 will be described. FIG. 6 is a flowchart showing the access permission process. When the communication unit 101 receives an access request from one mobile device 200, a connection is established by Peer to Peer (S201). Then, the permission unit 109 determines whether or not the identification ID of the one mobile device 200 transmitted when the connection is established matches the identification ID stored in the permission table 106 (S202). If it is determined that they match, the permission unit 109 permits the access request to the shared folder having the folder ID associated with the matching identification ID from the one mobile device 200, and Arbitrary files in the shared folder are transmitted to the mobile device 200 and can be browsed on the mobile device 200 (S203).

  In this way, the mobile device 100 can permit an access request to the shared folder from the mobile device 200, and the mobile device 200 can browse files held in the shared folder.

  Next, processing for deleting a shared folder will be described. Since the shared folder is generated when one or a plurality of mobile devices 200 exist within a predetermined range from the mobile device 100, the shared folder is unnecessary when all of the mobile devices 200 no longer exist. Become. Therefore, it is preferable to delete the shared folder when all of one or a plurality of mobile devices 200 move out of a predetermined range from mobile device 100. Here, processing when deleting a shared folder in this way will be described. FIG. 7 is a flowchart showing processing when deleting a shared folder.

  The search unit 102 in the mobile device 100 transmits a search request for one or a plurality of mobile devices 200 at a predetermined timing to the management server 300 (S301), from the management server 300, the telephone numbers of the one or more mobile devices 200 and A confirmation result including the identification ID is received (S302). Based on the confirmation result, the mobile device 200 existing in the vicinity (within a predetermined range) of the mobile device 100 is determined by the determination unit 104 (S303).

  Here, if it is determined that all of one or a plurality of mobile devices 200 exist, the process returns to S301, and a search request is made at predetermined intervals (S301). If it is determined that some or all of the one or more mobile devices 200 do not exist, the deletion unit 113 deletes the identification ID of the non-existent mobile device 200 from the permission table 106 (S304). That is, the identification ID of the mobile device 200 included in the confirmation result is compared with the identification ID stored in the permission table 106, and if all match, it is determined that all of the mobile devices 200 exist. If it is determined that an identification ID that is not included in the confirmation result exists in the permission table 106, the identification ID that is not included is deleted from the permission table 106 by the deletion unit 113.

  When the deletion unit 113 determines that all the identification IDs associated with the folder ID of one shared folder in the permission table 106 have been deleted (S306: YES), the corresponding shared folder is retrieved from the folder storage unit 108. It is deleted (S108). If it is determined that all identification IDs have not been deleted (S306: NO), the process returns to S301, and a search request is made at predetermined intervals (S301).

  As a result of such processing, the identification IDs of the mobile devices 200 that do not exist in the neighboring area within the predetermined range of the mobile device 100 are sequentially deleted from the permission table 106, and the identification IDs of all the mobile devices 200 are deleted from the permission table 106. In the case where it is done, the corresponding shared folder is deleted from the folder storage unit 108.

  Next, a modified example of the shared folder generation method shown in FIG. 5 will be described. FIG. 8 is a flowchart showing processing when a shared folder is generated with connection conditions.

  As shown in FIG. 8, when the mobile device 100 performs a search process for confirming the presence of the mobile device 200 in the vicinity, the mobile device list is transmitted from the management server 300, and an arbitrary mobile device is selected by the user. The identification ID of the selected mobile device is stored in the permission table 106, and a shared folder having a folder ID is generated (S401-S407). These processes are the same as S101 to S107 in FIG.

  When the shared folder is generated, an inquiry to the user is displayed on the display unit (not shown) as to whether or not the connection condition setting unit 111 gives a condition for connecting to the shared folder. Done. When the user gives an instruction to give (S408: YES), the connection condition setting unit 111 displays the folder condition selection screen on the display unit, and the user inputs the folder condition (S409). The folder conditions are stored in the connection condition storage unit 112, and the connection conditions are set (S410). This connection condition is, for example, a time period during which the mobile device 200 can connect to the mobile device 100.

  Next, a description will be given of processing when connection processing is performed for a shared folder in which connection conditions are set as described above. FIG. 9 is a flowchart showing a process for performing a connection process for a shared folder in which connection conditions are set.

  When the communication unit 101 receives an access request from one mobile device 200, a connection is established by Peer to Peer (S501). Then, the permission unit 109 determines whether or not the identification ID of the one mobile device 200 transmitted when the connection is established matches the identification ID stored in the permission table 106 (S502). If it is determined that they match, the permission unit 109 further determines whether there is a connection condition for the shared folder (S503). If there is a connection condition, whether the connection condition is satisfied. Is determined (S504). If the permission unit 109 determines that the connection condition is satisfied (S504: YES) or the connection condition is not set (S503: NO), an access request from one or more mobile devices 200 is permitted. Then, an arbitrary file in the shared folder stored in the folder storage unit 108 is transmitted to the mobile device 200 and can be browsed on the mobile device 200 (S505). In S502 and S504 described above, browsing of the teacher folder is not permitted if the table does not match the permission table or if the connection condition is not satisfied.

  In this way, the mobile device 100 can permit the access request to the shared folder from the mobile device 200 using the connection condition, and only the mobile device 200 that satisfies the connection condition can store the file held in the shared folder. You can browse.

  Next, an overview of these overall processes will be described. FIG. 10 is a sequence diagram showing processing of mobile device 100, mobile device 200, and management server 300.

  A search request is transmitted from the mobile device 100 to the management server 300 (S601), and a confirmation result is returned as a response (S602). Then, the mobile device 100 performs a shared folder generation process based on the confirmation result (S603).

  After that, when an access request is transmitted from the mobile device 200 to the mobile device 100 by Peerto Peer (S605), the mobile device 100 performs a permission process for the access request, such as a file held in the shared folder. The data is transmitted to the mobile device 200 and can be viewed on the mobile device 200 (S607).

  Thereafter, the mobile device 100 periodically accesses the management server 300 to make a search request for confirming the location of the mobile device 200 (S608). Here, the mobile device 200 is in a predetermined range of the mobile device 100. As a response, a confirmation result including the telephone number and identification ID of the mobile device 200 is returned (S609). Here, the identification ID stored in the permission table 106 is compared, and if it is determined that they all match, it is determined that it is OK.

  Thereafter, when the mobile device 200 moves out of the neighboring area outside the predetermined range of the mobile device 100 (S610), the position information is transmitted to the management server 300, and the position information after the movement of the mobile device 200 is stored in the position information table. Is stored (S611). For example, as shown in FIG. 1, the mobile device 200 moves outside the area A.

  Then, when a search request periodically executed from the mobile device 100 is executed, the management server 300 determines that the mobile device 200 is out of the predetermined range based on the position information. A confirmation result that does not include the identification ID is transmitted to the mobile device 100. In the mobile device 100, the identification ID stored in the permission table 106 is compared. If there is a mismatch, the mobile device 100 includes one of the mobile devices 200 included in the confirmation result but not included in the permission table 106. The identification ID is deleted. (S613).

  When the mobile device 200 outputs an access request to the mobile device 100 from the moved position (S614), the identification ID of the mobile device 200 has been deleted from the permission table in the mobile device 100. A message indicating permission is output (S615).

  As described above, when the mobile device 200 is within the predetermined range of the mobile device 100, the mobile device 200 can access the shared folder generated in the mobile device 100. Access to the shared folder is not allowed.

  Next, a modification of this embodiment will be described. FIG. 11 is a system configuration diagram showing a system configuration of a communication system including the mobile device 100a in the modification. As shown in FIG. 11, the communication system in this modification uses a wireless LAN system that includes an AP (Access Point) 500a and an AP 500b.

  Each of the mobile device 100a and the mobile device 200a can perform communication using a wireless LAN. When the mobile device 100a and the mobile device 200a are located in an access point formed by the AP 500a or AP 500b, the mobile device 100a and the mobile device are moved to the AP 500a and AP 500b. The telephone number and identification ID (MAC address) of the machine 200a can be stored as the location information. Then, upon receiving a search request from the mobile device 100, the AP 500a can return the stored location information as a confirmation result. The mobile device 100a can store the identification ID of the mobile device 200a in the permission table 106 based on the location information, and can perform permission processing for the access request to the shared folder from the mobile device 200a.

  The mobile device 100a has substantially the same configuration as the mobile device 100 shown in the block diagram of FIG. 2, but the function as the communication unit 101 mainly performs wireless LAN communication. That is different. The search server 102 that is the management server 300 as a partner to which the search request is transmitted is the AP 500a. In addition, the positioning unit 114 is not indispensable, and instead of managing the location information, the AP 500a and AP 500b manage the location information to determine a predetermined range (region A in FIG. 1) that enables access to the shared folder. Is.

  FIG. 12 shows the detailed processing. FIG. 12 is a sequence diagram showing processing of mobile device 100, mobile device 200, and AP 500a in a communication system using a wireless LAN.

  As shown in FIG. 12, when the mobile device 100a and the mobile device 200a are in the AP 500a, the AP 500a stores the identification IDs and telephone numbers of the mobile device 100a and the mobile device 200a as the location information (S701).

  A search request is transmitted from the mobile device 100a to the AP 500a (S702), and a confirmation result is returned as a response (S703). Then, the mobile device 100a performs a shared folder generation process based on the confirmation result (S704).

  After that, when an access request is transmitted from the mobile device 200a to the mobile device 100a by Peerto Peer (S705), the mobile device 100a performs a permission process for the access request, such as a file held in the shared folder. The data is transmitted to the mobile device 200a and can be browsed on the mobile device 200a (S708).

  Thereafter, the mobile device 100a periodically accesses the AP 500a and makes a search request for confirming the location of the mobile device 200a (S709). Here, the mobile device 200a is located in the AP 500a. As a response, a confirmation result including the telephone number and identification ID of the mobile device 200a is returned (S710). Here, the identification ID stored in the permission table 106 is compared, and if it is determined that they all match, it is determined that it is OK.

  Thereafter, when the mobile device 200a moves from the AP 500a to the AP 500b (S711), the AP 500a detects that fact and deletes the mobile device 200a from the location information (S712). For example, in FIG. 11, the location information is deleted when the mobile device 200a moves from the AP 500a to the AP 500b.

  Then, when a search request periodically performed from the mobile device 100a is executed, the AP 500a does not include the mobile device 200a in the location information, and therefore a confirmation result not including the mobile device 200 indicates that the mobile device 100a does not include the mobile device 200a. Sent to. In the mobile device 100a, the identification ID stored in the permission table 106 is compared, and if there is a mismatch, the mobile device 100a includes one of the mobile devices 200 included in the confirmation result but not included in the permission table 106. The identification ID is deleted. (S714).

  When the mobile device 200a located in the area of the AP 500b after moving outputs an access request to the mobile device 100a (S715), the identification ID of the mobile device 200a is deleted from the permission table in the mobile device 100a. Since there is, it is output that it is not permitted (S716).

  By such processing, when the mobile device 200b is located in the AP 500a, the telephone number of the mobile device 200b is registered in the AP 500a together with the location information, and the location information in which the mobile device 100a is registered in the AP 500a. Based on the above, the access request from the mobile device 200a can be permitted. Therefore, the shared folder can be set without setting by the user, and a user-friendly device can be realized.

  Next, operational effects of the mobile device 100a of the present embodiment will be described. In the mobile device 100 of the present embodiment, the search unit 102 searches for the mobile device 200 that is another communication device located within a predetermined range from the mobile device 100, and the acquisition unit 103 searches for the mobile device 200 that has been searched. An identification ID is acquired. The permission table 106 stores the identification ID of the mobile device 200 acquired by the acquisition unit 103. Upon receiving an access request for the shared folder from the mobile device 200 having the identification ID stored in the permission table 106, the permission unit 109 permits the access request. Accordingly, it is possible to set access to the shared folder without performing user setting, and it is possible to realize a user-friendly device.

  Further, in the mobile device 100 of the present embodiment, when the identification ID of the mobile device 200 is stored in the permission table 106, the generation unit 107 creates a shared folder that allows access from the mobile device 200 having the identification ID. By generating, it is possible to perform automatic setting processing without setting by the user including generation of the shared folder.

  Further, in the mobile device 100 of the present embodiment, the phone book data storage unit 105 stores phone book data used for making a phone call in advance. Then, the acquisition unit 103 acquires the identification ID and telephone number of the mobile device 200 searched by the search unit 102, and the determination unit 104 determines whether the acquired telephone number is included in the phone book data. to decide. When the determination unit 104 determines that the data is included in the phone book data, the permission table 106 stores an identification ID corresponding to the telephone number. Thereby, since the mobile devices 200 to which access is permitted using the phone book data are limited, access is not permitted from an unspecified number of users, and security can be improved.

  Further, in the mobile device 100 of the present embodiment, the search unit 102 periodically executes a search process for the mobile device 200 within a predetermined range with respect to the management server 300 or the AP 500a. If the determination unit 104 determines that the mobile device 200 having the identification ID stored in the permission table 106 does not exist in the predetermined range as a result of the periodic search, the deletion unit 113 does not exist. The identification ID of the mobile device 200 is deleted from the permission table 106. If the identification IDs of all the mobile devices 200 are deleted from the permission table 106 as a result of deletion, the deletion unit 113 can delete the shared folder with the folder ID corresponding to the identification ID. As a result, when there is no mobile device 200 that is an access request permission target, the storage area can be efficiently used by deleting the shared folder for the mobile device 200.

  In the mobile device 100 of the present embodiment, the connection condition setting unit 111 receives a connection condition for the shared folder from the user and stores it in the connection condition storage unit 112. Then, the permission unit 109 can perform permission for the access request based on the identification ID stored in the permission table 106 and the connection condition. Therefore, security can be further improved. For example, the connection condition includes an accessible time zone and a scheduled action set in the scheduler (such as a stay planned position).
