However, since the connection destination setting requires input over a plurality of items, it is not always possible for the user of an information communication device such as a smartphone to easily perform the setting.

Therefore, for example, Japanese Patent Application Laid-Open No. 2015-084580 “Mobile Station Device and Position Management Device” and Patent Document 2 Japanese Patent Application Laid-Open No. 2017-022443 “Setting Information Generator, Method, Setting Terminal and Method”. The technology described in the above has been proposed, and an attempt is made to facilitate the setting by providing a communication device having a wireless relay function, for example, an APN list in which information on the connection destination is registered in advance on the wireless LAN router side. .. FIG. 7 is a block configuration diagram showing an internal configuration of a current communication device as described in Patent Document 1. As shown in FIG. 7, the current communication device 100a includes a control unit 101, a WAN (Wide Area Network) communication IF (Interface) 102, and a LAN (Local Area Network) communication IF 103, which are provided in a general communication device.

(Explanation of operation of the first embodiment of the present invention)
Next, an example of the operation of the wireless LAN network system shown in FIG. 1 as the first embodiment will be described in detail with reference to the flowcharts of FIGS. 2 and 3. First, the operation will be described with reference to the flowchart of FIG. FIG. 2 is a flowchart showing an example of the operation of the first embodiment of the wireless LAN network system shown in FIG. 1, and information about the connection destination registered in the APN list 301 held by the server 300. An example of the operation from the acquisition by the communication device 200 to the setting of the connection destination in the wide area communication network of the communication device 100 is shown.

In the flowchart of FIG. 2, first, the information communication device 200 connects the LAN communication IF 203 to the LAN communication IF 103 of the communication device 100 by Wi-Fi (wireless) (step S1). Next, the management unit 201 of the information communication device 200 acquires information on the connection destination in the wide area communication network of the communication device 100 from the communication device 100 by Wi-Fi (wireless) communication with the communication device 100. The selection condition information (that is, information on the model, carrier, destination, etc. of the communication device 100) required for this is acquired (step S2). After that, the management unit 201 of the information communication device 200 confirms whether or not the WAN communication IF 202 of the information communication device 200 is in a state where the WAN side communication with the server 300 is possible (step S3).

If communication with the server 300 is possible (in the case of Yes in step S4), the operation proceeds to step S6, but communication with the server 300 is impossible. If this is the case (No in step S4), the Wi-Fi function of the LAN communication IF203 is temporarily disabled in order to cancel the Wi-Fi (wireless) connection with the communication device 100. And requesting the communication device 100 to disable Wi-Fi (wireless) communication (step S5).

As a result, the Wi-Fi (wireless) connection with the communication device 100 is canceled, and WAN side communication with the server 300 becomes possible. Therefore, the management unit 201 of the information communication device 200 is based on the selection condition information required for acquiring the information regarding the connection destination in the wide area communication network of the communication device 100, which has been received earlier from the communication device 100. Information (APN, etc.) regarding an appropriate connection destination is selected and acquired from the APN list 301 of the server 300 (step S6). After that, the management unit 201 of the information communication device 200 connects the LAN communication IF 203 to the LAN communication IF 103 of the communication device 100 by Wi-Fi (wireless) (step S7). Then, the management unit 201 of the information communication device 200 transmits information (APN or the like) regarding the connection destination in the wide area communication network of the communication device 100 acquired from the server 300 in step S6 to the communication device 100, and the information communication device 200 is described.

Then, the control unit 101 of the communication device 100 records the time when the Wi-Fi (wireless) communication is disabled (step S13).

As a result, as described above in the description of FIG. 2, the information communication device 200 is disconnected from the Wi-Fi (wireless) connection with the communication device 100, and the WAN communication IF202 is an Internet line meaning a wide area communication network. Communication to 500 becomes possible, and communication with server 300 becomes possible. Thus, as described above in the description of FIG. 2, the information communication device 200 is a selection required for acquiring information regarding a connection destination in the wide area communication network of the communication device 100 that has been received earlier from the communication device 100. Based on the condition information, it is possible to perform an operation of acquiring information on a connection destination such as an appropriate APN from the APN list 301 of the server 300.

On the other hand, the control unit 101 of the communication device 100 is instructed by the user to enable Wi-Fi (wireless) communication via the operation IF 104, or a predetermined fixed time (for example, 3 minutes) elapses. Wait until (step S14). That is, first, when there is an instruction from the user to enable Wi-Fi (wireless) communication via the operation IF 104 (in the case of Yes in step S15), the operation proceeds to step S17. However, if there is no instruction from the user (No in step S15), then it is confirmed whether or not a predetermined fixed time (for example, 3 minutes) has elapsed (step S16), and still, If the fixed time has not elapsed (No in step S16), the process returns to step S14 and returns to the operation of confirming whether or not there is a user's instruction from the operation IF 104. Further, when a predetermined fixed time (for example, 3 minutes) has elapsed (in the case of Yes in step S16), the operation proceeds to step S17.

When there is an instruction from the user to enable Wi-Fi (wireless) communication via the operation IF104, or when a predetermined fixed time (for example, 3 minutes) elapses and the operation shifts to the operation of step S17, communication occurs. The control unit 101 of the device 100 controls the LAN communication IF 103 of the communication device to enable Wi-Fi (wireless) communication with the information communication device 200 (step S17). As a result, the communication device 100 is reconnected to the information communication device 200, and information (APN or the like) regarding the latest connection destination regarding the communication device 100 acquired from the server 300 in the information communication device 200 is transmitted. .. When the control unit 101 of the communication device 100 receives the latest information (APN or the like) regarding the connection destination in the wide area communication network of the communication device 100 sent from the information communication device 200, the control unit 101 of the communication device 100 in the wide area communication network of the communication device 100. As information about the connection destination, it is set in the communication device 100 (step S18). After that, the control unit 101 of the communication device 100 connects to the Internet line 500, which means a wide area communication network such as an LTE network, via the WAN communication IF 102, based on the information about the set connection destination ( Step S19).

That is, in the first embodiment, the communication device 100 is connected to the communication device 100 having a wireless relay function by LAN, and the information regarding the connection destination in the wide area communication network is already set. By using an information communication device 200 capable of WAN connection with a server 300 that has information on the latest connection destination required for connecting to a wide area communication network as an APN list 301, the communication device 100 can be used. On the other hand, since the information (APN, etc.) regarding the latest connection destination required for connection in a wide area communication network such as an LTE network can be automatically set, the user of the communication device 100 is complicated about the connection destination. It is possible to automatically set the information about the latest connection destination of the wide area communication network in the communication device 100 and perform communication without making the setting.

The reason is that the information communication device 200 can receive selection condition information necessary for acquiring information (APN, etc.) regarding the latest connection destination of the communication device 100 from the communication device 100 by LAN connection. This is because the WAN connection can independently communicate with the server 300 and acquire information (APN, etc.) regarding the latest connection destination of the target communication device 100 from the server 300. Thus, the communication device 100 can receive information (APN, etc.) regarding the latest connection destination of the communication device 100 from the information communication device 200 by LAN connection, and can automatically set the connection destination. Therefore, the user of the communication device 100 does not need to perform complicated input for setting the connection destination.

Further, the information communication device 200 receives the selection condition information required for acquiring the latest connection destination information of the communication device 100 from the communication device 100, and then the server via the Internet line 500 which means a wide area communication network. When a situation occurs in which wireless communication with the 300 is not possible, the user of the information communication device 200 temporarily disables Wi-Fi (wireless) communication with the communication device 100 without performing any operation. , The operation of switching the LAN communication state to the state of performing WAN communication is performed. Thus, the information communication device 200 is in a state where it can be connected to the Internet line 500 of the wide area communication network capable of using the Internet communication, and accesses the server 300 via the Internet line 500. be able to. Although the details will be described later in the third embodiment, the information communication device 200 is not connected to the server 300 via the Internet line 500, but is capable of Internet communication. Even if you try to connect to the server 300 using an access point, you can make a Wi-Fi (wireless) connection with another access point by disabling the Wi-Fi (wireless) communication of the communication device 100. Therefore, it is possible to eliminate the need for the user of the information communication device 200 to select another access point and perform an operation for connecting to the server 300.

Next, a second embodiment of the wireless communication network system according to the present invention will be described in detail with reference to the drawings. In the second embodiment, since the information communication device 200 does not hold information on the original SSID (Service Set Identifier) and password currently set in the communication device 100 shown in FIG. 1, the communication device 200 Even if the Wi-Fi (wireless) connection between the 100 and the information communication device 200 cannot be set, the Wi-Fi (wireless) connection between the communication device 100 and the information communication device 200 is ensured. At the same time, the information communication device 200 can make a Wi-Fi (wireless) connection with the communication device 100 at the same time as enabling the operation of setting information about the connection destination in the wide area communication network of the communication device 100. Explains the case of automatically setting to the above state. The system configuration of the wireless communication network system and the internal configurations of the communication device, the information communication device, and the server in the second embodiment are the same as those in FIG. 1 in the first embodiment, and are duplicated here. I will omit the explanation given.

(Explanation of operation of the second embodiment of the present invention)
An example of the operation of the second embodiment in the wireless LAN network system shown in FIG. 1 will be described in detail with reference to the flowcharts of FIGS. 4A and 4B. Two drawings, FIG. 4A and FIG. 4B, constitute one flowchart. Since it is difficult to draw the entire flowchart on one paper due to the size limitation of the paper, the first half of the flowchart is drawn in FIG. 4A and the second half of the flowchart is drawn in FIG. 4B. Then, A and B circled at the lower end of FIG. 4A are connected to A and B circled at the upper end of FIG. 4B, respectively. That is, FIGS. 4A and 4B are flowcharts showing an example of the operation of the second embodiment of the wireless LAN network system shown in FIG.

In the flowcharts of FIGS. 4A and 4B, since the Wi-Fi (wireless) connection between the communication device 100 and the information communication device 200 cannot be established, the user of the communication device 100 first operates. The IF 104 is operated to temporarily change the original SSID (Service Set Identifier) and password currently set in the communication device 100 to a predetermined known fixed SSID and password (step S21). Here, the communication device 100 set to the fixed SSID and password is set to a state in which the setting of the communication device 100 cannot be changed from any external device or device in consideration of security measures ( Step S22). That is, while the SSID and password of the communication device 100 are temporarily switched to the predetermined fixed SSID and password and set, the wide area communication of the communication device 100 transmitted from the information communication device 200 is performed. It is set to a state in which reception of information from the outside is prohibited at all, except for the period for receiving information on the latest connection destination on the network.

Next, the management unit 201 of the information communication device 200 makes a Wi-Fi (wireless) connection with the communication device 100 set to the fixed SSID and password (step S23). After that, the management unit 201 of the information and communication device 200 performs the same operation as in steps S2 to S6 of FIG. That is, first, the management unit 201 of the information communication device 200 receives selection condition information (that is, the model of the communication device 100) required for acquiring information on the connection destination in the wide area communication network of the communication device 100 from the communication device 100. After acquiring (information on the carrier, destination, etc.) (step S24), it is confirmed whether or not the WAN communication IF 202 of the information communication device 200 is capable of WAN side communication with the server 300 (step). S25), if possible (in the case of Yes in step S26), the server is based on the selection condition information required to acquire the information regarding the connection destination of the communication device 100 received from the communication device 100. Information (APN, etc.) regarding an appropriate connection destination is selected and acquired from the APN list 301 of 300 (step S44).

On the other hand, when the WAN communication IF 202 of the information communication device 200 cannot communicate with the server 300 on the WAN side (No in step S26), the management unit 201 of the information communication device 200 is temporarily used. Is set to disable Wi-Fi (wireless) communication with the communication device 100, and requests the communication device 100 to disable Wi-Fi (wireless) communication (step S27). Further, the control unit 101 of the communication device 100 that has received the invalidation request performs the same operation as in steps S11 to S13 of FIG. That is, when a request for temporarily disabling Wi-Fi (wireless) communication is received from the information communication device 200 (step S28), the control unit 101 of the communication device 100 receives the Wi-Fi (wireless) communication with the information communication device 200. The (wireless) communication is disabled (step S29), and the time when the Wi-Fi (wireless) communication is disabled is recorded (step S30).

On the other hand, in the information communication device 200, the Wi-Fi (wireless) communication with the information communication device 200 is invalidated on the communication device 100 side as well, and the Wi-Fi (wireless) connection with the communication device 100 is canceled. In this state, the WAN communication IF 202 of the information communication device 200 is in a state where WAN side communication with the server 300 is possible. Therefore, the management unit 201 of the information communication device 200 performs the same operation as in the case of step S44, and is based on the selection condition information required for acquiring the information regarding the connection destination of the communication device 100 received from the communication device 100. Then, information (APN, etc.) regarding an appropriate connection destination is selected and acquired from the APN list 301 of the server 300 (step S31).

Further, when the control unit 101 of the communication device 100 finishes the operation of step S30, the control unit 101 performs the same operation as steps S14 to S17 of FIG. That is, the control unit 101 of the communication device 100 is instructed by the user to enable Wi-Fi (wireless) communication via the operation IF 104, or a predetermined fixed time (for example, 3 minutes) elapses. (Step S32), if there is a user instruction (in the case of Yes in step S33), or after the certain time (for example, in the case of Yes in step S34) elapses, LAN communication of the communication device is performed. The IF 103 is controlled to enable Wi-Fi (wireless) communication with the information communication device 200 (step S35). As a result, the information communication device 200 performs the same operation as in step S7 of FIG. 2, and makes a Wi-Fi (wireless) connection with the communication device 100 in which the fixed SSID is set (step S36).

However, here, since the communication device 100 is set in a state in which no setting can be made from an external device or device in step S22, a fixed SSID is set in the management unit 201 of the information communication device 200. The operation IF 104 of the communication device 100 is operated with respect to the communication device 100, so that the setting of the communication device 100 can be changed from the information communication device 200 which is an external device of the communication device 100. Request to set (step S37). Upon receiving the request from the information communication device 200, the control unit 101 of the communication device 100 displays the request on a screen and notifies the user of the communication device. The user who has visually recognized the notification performs an operation of permitting the setting of the communication device 100 from the external information communication device 200 via the operation IF 104 (step S38).

When the communication device 100 in which the fixed SSID is set shifts to a state in which it can be set from the outside, the same operation as in step S8 of FIG. 2 is performed, and the management unit 201 of the information communication device 200 performs step S31 or step S44. Information (APN, etc.) regarding the latest connection destination in the wide area communication network of the communication device 100 acquired from the server 300 is transmitted to the communication device 100, and the communication device 100 is set (step S39).

Next, when the control unit 101 of the communication device 100 is set with the information regarding the connection destination in the wide area communication network of the communication device 100, the original SSID of the communication device 100 before the change is set for the information communication device 200. After notifying the information regarding the password (step S40), the SSID and password of the communication device 100 are returned to the original SSID and password before the change (step S41). On the other hand, when the management unit 201 of the information communication device 200 receives the information regarding the original SSID and password of the communication device 100 transmitted from the communication device 100, the management unit 201 and the communication device 100 in a state of being returned to the original SSID and password. Create and save a connection profile for making a Wi-Fi (wireless) connection (step S42).

Further, the control unit 101 of the communication device 100 performs the same operation as in step S19 of FIG. 3, and based on the information regarding the set connection destination, establishes a wide area communication network such as an LTE network via the WAN communication IF 102. The connection with the meaning Internet line 500 is performed (step S43).

As described in detail above, in the second embodiment, since the information communication device 200 does not hold the information (SSID and password) required for connection with the communication device 100, the communication device 100 Even if the Wi-Fi (wireless) connection between the information communication device 200 and the information communication device 200 cannot be set, the communication device 100 is temporarily changed to a predetermined known fixed SSID and password to be set. By doing so, it is possible to reliably make a Wi-Fi (wireless) connection between the communication device 100 and the information communication device 200. Therefore, the connection profile is created by receiving the information on the original SSID and password of the communication device 100 while enabling the operation of setting the information on the connection destination in the wide area communication network of the communication device 100. After that, the information communication device 200 can also make a Wi-Fi (wireless) connection with the communication device 100.

Further, when the SSID and the password are changed to a fixed SSID and the password is set, the information and communication device 200 may be affected by the external device or device except for the period during which the information and communication device 200 sets the information regarding the connection destination of the communication device 100. By shifting to a state in which the setting for the communication device 100 is completely prohibited, a security measure for preventing unauthorized access is also realized.

<Third Embodiment of the present invention>
Next, a third embodiment of the wireless communication network system according to the present invention will be described in detail with reference to the drawings. In the third embodiment, instead of the information communication device 200 shown in FIG. 1, an information communication device 200A having a LAN communication IF203 but not a WAN communication IF202 is used, and a wide area of the communication device 100 is used. A case where information about the connection destination in the communication network is set in the communication device 100 will be described. The information communication device 200A of the third embodiment includes a case where the information communication device 200A cannot be used due to a failure or the like even if the WAN communication IF202 is provided.

(Structure example of the third embodiment of the present invention)
First, a third embodiment of the system configuration of the wireless communication network system according to the present invention will be described in detail with reference to FIG. FIG. 5 is a system configuration diagram showing a third embodiment of the system configuration of the wireless communication network system according to the present invention. Unlike the case of FIG. 1, the wireless communication network system shown in FIG. 5 includes at least a communication device 100, an information communication device 200A, a server 300, and an access point 400. Here, the communication device 100 and the server 300 have exactly the same internal configuration as in the case of FIG. 1, but the information communication device 200A has an internal structure in which the WAN communication IF 202 is deleted from the information communication device 200 of FIG. It consists of a composition.

Further, the access point 400 shown in FIG. 5 is a device similar to a public wireless router device having a wireless relay function used in, for example, a public wireless LAN, and provides information on connection destinations in a wide area communication network such as an LTE network. While holding it inside, it is configured to include at least WAN communication IF402 and LAN communication IF403. Then, a Wi-Fi (wireless) connection is made to an information communication device 200 that does not have a WAN communication IF, and data transmitted / received to / from the server 300 via the Internet line 500, which means a wide area communication network, is transmitted to the information communication device. It is possible to relay to 200A.

(Explanation of Operation of Third Embodiment of the Present Invention)
Next, as a third embodiment, an example of the operation in the wireless LAN network system shown in FIG. 5 will be described in detail with reference to the flowchart of FIG. FIG. 6 is a flowchart showing an example of the operation of the wireless LAN network system shown in FIG. 5 as a third embodiment of the communication device 100 acquired by the information communication device 200A from the server 300 via the access point 400. An operation example until the information about the connection destination is set in the communication device is shown. The operation of the control unit 101 of the communication device 100 when the Wi-Fi (wireless) function of the communication device 100 is disabled is the same as that of the flowchart of FIG. 3 in the first embodiment. The description here will be omitted. Hereinafter, the difference from the flowchart of FIG. 2 of the first embodiment will be mainly described with reference to the flowchart of FIG.

As shown in the system configuration of FIG. 5, since the information communication device 200A in the third embodiment does not include the WAN communication IF202, the information communication device 200A alone is an Internet line meaning a wide area communication network. Communication via 500 is not possible. Therefore, the information communication device 200A in the third embodiment searches for a public wireless LAN router (public access point) used as an access point 400, for example, in a public wireless LAN or the like, and is detected as a search result. Using the wireless relay function using the LAN communication IF403 and the WAN communication IF402 of the access point 400, communication is performed via the Internet line 500, which means a wide area communication network. That is, the LAN communication IF203 of the information communication device 200A and the LAN communication IF403 of the access point 400 can be Wi-Fi (wirelessly) connected by using the access point 400 as a master unit and the information communication device 200A as a slave unit. .. Then, the access point 400 having a relay function can communicate with the Internet line 500 via the WAN communication IF402. Therefore, the information communication device 200A can communicate with the Internet line 500, which means a wide area communication network, via the LAN communication IF203, the LAN communication IF403, and the WAN communication IF402.

In the flowchart of FIG. 6, each step from step S51 to step S55 performs exactly the same operation as step S1 to step S5 of FIG. 2 of the first embodiment, and thus the description thereof will be omitted here. Then, in the flowchart of FIG. 6, since the information communication device 200A itself cannot communicate on the WAN side (in the case of No in step S54), the Wi-Fi (wireless) communication with the communication device 100 is temporarily disabled. After the conversion (step S55), in the next step S56, the information communication device 200A searches for the access point 400 used for the public wireless LAN or the like (step S56).

If the access point 400 can be detected as the search result, the information communication device 200A confirms whether or not the Wi-Fi (wireless) connection with the access point 400 can be made ( In step S57), if the Wi-Fi (wireless) connection cannot be made (in the case of No in step S57), the process returns to step S56 until the Wi-Fi (wireless) connection can be made. , The search operation of another access point 400 is repeated.

If a Wi-Fi (wireless) connection with the detected access point 400 can be made (in the case of Yes in step S57), the information communication device 200A accesses the server 300 via the access point 400. Then, as in the case of step S6 of FIG. 2, based on the selection condition information required for acquiring the information regarding the connection destination in the wide area communication network of the communication device 100 previously received from the communication device 100, Information (APN, etc.) regarding an appropriate connection destination is selected and acquired from the APN list 301 of the server 300 (step S58).

In the subsequent steps S59 and S60, exactly the same operations as in steps S7 and S8 of FIG. 2 of the first embodiment are performed, and the management unit 201 of the information communication device 200A performs Wi with the communication device 100. -Fi (wireless) connection is made (step S59), and information (APN or the like) regarding the latest connection destination in the wide area communication network acquired from the server 300 in step S58 is transmitted to the communication device 100 to perform the communication. It is set as information indicating the connection destination of the device (step S60).

As described above, as in the third embodiment, even when the information communication device 200A for Wi-Fi (wireless) connection with the communication device 100 does not have the WAN communication IF202, a public wireless LAN or the like By searching for the access point 400 used in the above and accessing the server 300 via the access point 400, it is possible to set information regarding the connection destination of the communication device 100 in the wide area communication network.
