Description

  The present invention relates to a connection information sharing server, a connection information sharing method, and a connection information sharing server program that provide connection information to a nearby terminal in response to a request from a communication terminal.

  In recent years, various services are provided to users by connecting a mobile terminal connected to a public network to a Web server or the like. In particular, with the advent of smartphones (high-function mobile phones), it has become possible to perform advanced services that have been provided for personal computers with mobile phones.

  In addition to smartphones, various devices that have not been connected to the conventional network are compatible with network connections, and exchanges information with other devices while providing advanced functions are increasing. .

  On the other hand, there is a problem that the complexity and complexity of managing connection information for connecting to each terminal has increased due to the complexity of the network structure and the increase in the number of terminals connected to the network.

  In response to such a problem, a terminal management apparatus that manages information on terminals connected to a network has been disclosed.

JP 2013-69245 A

  According to Patent Document 1, the terminal management apparatus 10 acquires terminal identification information and terminal environment information of a terminal in response to being connected to a terminal, and uses the application service usage contract in advance in the terminal management apparatus 10. The server information for identifying the server of the provider providing the application service is stored in association with the terminal identification information of the terminal managing the terminal, and the terminal is authenticated depending on whether or not the acquired terminal identification information is stored. When the terminal is authenticated, the acquired terminal identification information and the terminal environment information are stored, and in response to the terminal environment information transmission request, the terminal identification information of the terminal requested to transmit is stored based on the acquired server information. The terminal is managed by transmitting the terminal environment information.

[Outline of device detection system]
FIG. 1 is a schematic diagram for explaining a connection information sharing system 1 which is a preferred embodiment of the present invention. The connection information sharing system 1 will be described with reference to FIG.

  In the connection information sharing system 1, first, the communication terminal 10 acquires current position information of the communication terminal 10 (step S01). Here, the location information is information for specifying a reference location for detecting a terminal existing in the vicinity, and it is common to acquire latitude and longitude using GPS or Wi-Fi. However, more detailed position information may be acquired via wireless communication based on the beacon terminal.

  Next, the communication terminal 10 transmits the acquired position information to the connection information sharing server 200 (step S02). When receiving the location information, the connection information sharing server 200 extracts the terminal 50 within the predetermined range from the terminal location database 250 (step S03). Here, the terminal 50 within the predetermined range refers to the terminal 50 existing in a circular or rectangular range centered on the received position information. This range may be arbitrarily determined for each system or communication terminal 10.

  Further, the connection information sharing server 200 extracts a connection method that can be used by each terminal 50 with reference to the connection method database 251 for the extracted terminal 50 (step S04). Here, since it is considered that information of the communication terminal 10 itself is also stored, connection methods that can be used by the communication terminal 10 are also extracted at the same time. By doing so, a common connection method can be specified as a connection method capable of connecting both terminals.

  Subsequently, the connection information sharing server 200 extracts authentication information and security conditions of each terminal with reference to the terminal security database 252 for the extracted terminal 50 (step S05). Further, information on whether the communication terminal 10 satisfies the security condition may be acquired from the communication terminal 10.

  Then, the connection information sharing server 200 transmits the extracted various types of information to the communication terminal 10 (step S06). However, for the terminal 50 for which the security condition is set, the authentication information may be transmitted only when the terminal 10 satisfies the security condition.

  Finally, the communication terminal 10 that has received the information uses the information to connect to each terminal 50 (step S07). The above is the outline of the connection information sharing system 1. In FIG. 1, the IP address is a private IP address. However, a global IP address may be used. If the IP address is a private IP address, information such as an SSID that can identify the network is also written. May be. Further, except for Wi-Fi, since many short-range wireless communications are irrelevant to the IP address at the time of connection, the use of the IP address is not an essential configuration.

[System configuration of device detection system]
FIG. 2 is a system configuration diagram of the connection information sharing system 1 which is a preferred embodiment of the present invention. The connection information sharing system 1 includes a public line network 3 (Internet network, third generation, fourth generation communication network, etc.), GPS 5, communication terminal 10, a plurality of terminals 50, and a connection information sharing server 200.

The communication terminal 10 and each terminal 50 are connected by a LAN. Communication in the connection information sharing system 1 may be wireless communication or wired communication.

  The terminal 50 is a home or business electronic device that can perform data communication. In addition, since the object of the present invention is to provide the communication terminal 10 with information for connecting to the terminal 50, the communication terminal 10 and each terminal 50 are not communicably connected at this stage.

  The connection information sharing server 200 may be a general server having functions to be described later.

[Description of each function]
FIG. 3 is a diagram illustrating the functional blocks of the communication terminal 10, the terminal 50, and the connection information sharing server 200 and the relationship between the functions.

  The communication terminal 10 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like as the control unit 11, and the communication unit 12 is, for example, WiFi (Wireless) compliant with IEEE 802.11. Fidelity) compatible devices, wireless devices compliant with IMT-2000 standards such as third-generation and fourth-generation mobile communication systems, GPS and other location information acquisition devices, and other devices compatible with wireless communication standards.

  In the communication terminal 10, when the control unit 11 reads a predetermined program, the position information acquisition module 13, the position information transmission module 14, the connection method reception module 15, the authentication information reception module 16, in cooperation with the communication unit 12, The security condition related information transmission module 17 is realized.

  Similarly, the connection information sharing server 200 includes a CPU, a RAM, a ROM, and the like as the control unit 201, and includes, for example, a WiFi compatible device compliant with IEEE 802.11 (may be wired) as the communication unit 202. . In addition, the connection information sharing server 200 includes a data storage unit using a hard disk or a semiconductor memory as the storage unit 203. The connection information sharing server 200 includes a terminal location database 250, a connection method database 251, and a terminal security database 252 in the storage unit 203.

  When the control unit 201 of the connection information sharing server 200 reads a predetermined program, the terminal location acquisition module 204, the connection information transmission module 205, the authentication information transmission module 206, and the security condition determination module 207 cooperate with the communication unit 202. To realize. Further, the control unit 201 of the connection information sharing server 200 reads a predetermined program, so that the proximity terminal extraction module 208, the connection method identification module 209, the connection method extraction module 210, the authentication information extraction, in cooperation with the storage unit 203. A module 211 and a security condition extraction module 212 are realized.

[Connection information sharing process]
FIG. 4 is a flowchart of connection information sharing processing executed by the communication terminal 10 and the connection information sharing server 200. The processing performed by the module of each device described above will be described together with this processing.

  First, the communication terminal 10 and the connection information sharing server 200 execute proximity terminal extraction processing in order to detect a terminal in the vicinity of the communication terminal 10 (step S01).

[Nearby terminal extraction processing]
FIG. 5 is a flowchart of proximity terminal extraction processing executed by the communication terminal 10 and the connection information sharing server 200. The processing performed by the module of each device described above will be described together with this processing.

  First, the position information acquisition module 13 of the communication terminal 10 acquires the position information of the current position of the communication terminal 10 (step S31). Here, the location information is information for specifying a reference location for detecting a terminal existing in the vicinity, and it is common to acquire latitude and longitude using GPS or Wi-Fi. However, more detailed position information may be acquired via wireless communication based on the beacon terminal. Specifically, it is possible to acquire position information with an accuracy of several meters using power-saving short-range wireless communication such as BLE (Bluetooth Low Energy).

  Next, the communication terminal 10 transmits the acquired position information to the connection information sharing server 200 (step S32). The terminal location acquisition module 204 of the connection information sharing server 200 receives the location information (step S33).

  When the connection information sharing server 200 receives the position information, the proximity terminal extraction module 208 extracts the terminal 50 within the predetermined range from the terminal position database 250 (step S34). Here, the terminal 50 within the predetermined range refers to a terminal existing in a circular or rectangular range centered on the received position information. This range may be arbitrarily determined for each system or communication terminal 10.

  FIG. 6 is an example of a terminal location table in the terminal location database 250. In the terminal location table, the terminal ID and location information of the terminal 50, and the IP address for accessing the terminal are stored. Here, the position information is represented by latitude and longitude, but the position information is not limited to this as long as the position information can be uniquely represented. In the case of a terminal that does not use the Internet for connection, an IP address is not always necessary.

  In the terminal extraction by the proximity terminal extraction module 208, the conditional expression can be obtained by expressing the extraction range by a mathematical expression and applying the received position information of the communication terminal 10. Then, by extracting all the terminals 50 registered in association with the position information corresponding to the conditional expression, the terminals 50 within the predetermined range can be extracted.

  The above is the procedure of the proximity terminal extraction process. Returning to the connection information sharing process, the communication terminal 10 repeatedly executes the following processes from step S13 to step S24 for each extracted terminal 50 (step S12).

  First, the connection method extraction module 210 of the connection information sharing server 200 extracts connection methods that can be used by the terminal 50 from the connection method database 251 (step S13).

  FIG. 7 is an example of a connection method table in the connection method database 251. In the connection method table, the terminal ID of each terminal 50 and the available connection methods are stored in association with each other. Here, the terminal ID in the connection method table and the terminal ID in the terminal position table correspond to 1: 1. Therefore, by extracting information with the terminal ID of the terminal 50 that is currently processing, the connection methods that can be used by the terminal 50 can be extracted.

  Subsequently, the connection method specifying module 209 of the connection information sharing server 200 specifies a connection method capable of connecting the communication terminal 10 and the terminal 50 (step S14). Specifically, a connection method that can also be used for the communication terminal 10 may be extracted from the connection method database 251 and a common connection method may be extracted. However, depending on the communication standard, the standby for transmission and reception may not be common, so if it is limited to either transmission or reception, it may be considered that the correspondence is shared.

  Then, the connection information transmission module 205 of the connection information sharing server 200 transmits the identified connection method to the communication terminal 10 (step S15). At this time, if there is necessary terminal information, for example, an IP address, depending on the connection method, it may be transmitted simultaneously. The connection method receiving module 15 of the communication terminal 10 receives the connection method and the like (step S16).

  Next, the security condition extraction module 212 of the connection information sharing server 200 extracts the security conditions of the terminal 50 from the terminal security database 252 (step S13).

  FIG. 8 is an example of a terminal security table in the terminal security database 252. In the terminal security table, the terminal ID of each terminal 50, authentication information, and security conditions serving as a reference for determining whether authentication information can be provided are stored in association with each other. Here, the terminal ID in the connection method table and the terminal location table and the terminal ID in the terminal security table correspond to 1: 1. Therefore, the security conditions and authentication information of the terminal 50 can be extracted by extracting information with the terminal ID of the terminal 50 that is currently processing.

  After extracting the security conditions, the security condition determination module 207 of the connection information sharing server 200 requests the communication terminal 10 to transmit information of the communication terminal 10 regarding the security conditions (step S18). On the other hand, the security condition related information transmission module 17 of the communication terminal 10 acquires the related information from the terminal and transmits it to the connection information sharing server 200 (step S19).

  Here, as related information, for example, data stored in a storage unit such as an address book, and device-specific information such as a MAC address can be cited, but the related information is not limited thereto. If no security condition is set for the terminal 50, steps S18 and S19 may be omitted.

  Next, the security condition extraction module 212 determines whether the communication terminal 10 satisfies the security condition of the terminal 50 based on the security condition related information received from the communication terminal 10 (step S20). Here, when the communication terminal 10 does not satisfy the security condition of the terminal 50 (step S20: “NO”), the authentication information is not shared, the processing relating to the terminal 50 is finished, and the next terminal 50 is finished. To step S13 (step S24).

  On the other hand, when the communication terminal 10 satisfies the security conditions of the terminal 50 (step S20: “YES”), the authentication information extraction module 211 of the connection information sharing server 200 authenticates the terminal 50 from the terminal security database 252. Information is extracted (step S21), and the authentication information extracted by the authentication information transmission module 206 is transmitted to the communication terminal 10 (step S22). The authentication information receiving module 16 of the communication terminal 10 receives the authentication information (step S23).

  With the above processing, the processing related to the terminal 50 ends, and when there is an unprocessed terminal 50, the processing returns to step S13 regarding the terminal 50 (step S24). When the process is completed for all the terminals 50 extracted by the proximity terminal extraction process, the connection information sharing process is terminated as it is.

  Through the above processing, the communication terminal 10 can receive a connection method with a nearby terminal 50, and can receive authentication information if the security setting is satisfied. Thereby, since communication with the terminal 50 becomes possible, you may start communication with the terminal 50 as needed.

  FIG. 9 is an example of a display of the communication terminal 10 that has received the connection method and the authentication information. The terminal 50 in the vicinity of the extracted information is represented by icons 91, 92, and the like, and information 93 of the terminal 50 is displayed beside it. When the connection button 94 is pressed down, connection to the terminal 50 is started. If the connection method cannot be specified or the security conditions are not satisfied, the connection button 94 may be hidden.

  The above is the procedure of the connection information sharing process.

  The means and functions described above are realized by a computer (including a CPU, an information processing apparatus, and various terminals) reading and executing a predetermined program. The program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, CD (CD-ROM, etc.), DVD (DVD-ROM, DVD-RAM, etc.), for example.
