That is, first, when there is a user's instruction to validate the Wi-Fi (wireless) communication via the operation IF 104 (Yes in step S15), the process proceeds to the operation in step S17. However, if there is no instruction from the user (in the case of No in step S15), then it is checked whether a predetermined time (for example, 3 minutes) which has been determined in advance has elapsed (step S16). If the predetermined time has not elapsed (in the case of No at step S16), the process returns to step S14, and returns to the operation of confirming whether the user's instruction from the operation IF 104 is given. When a predetermined time (for example, 3 minutes) has passed (in the case of Yes in step S16), the process proceeds to step S17.

  Communication is performed when there is a user's instruction to enable Wi-Fi (wireless) communication via the operation IF 104 or when a predetermined fixed time (for example, 3 minutes) elapses and the operation of step S17 is performed. The control unit 101 of the device 100 controls the LAN communication IF 103 of the communication device to validate 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) on the latest connection destination regarding the communication device 100 acquired from the server 300 in the information communication device 200 is transmitted. .

The operation of switching the LAN communication state to the state of performing WAN communication is performed. Thus, the information communication device 200 is ready to be connected to the Internet line 500 of a wide area communication network that can use 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 does not connect the information communication device 200 itself to the server 300 via the Internet line 500, but other devices capable of Internet communication. Even when trying to connect to the server 300 using an access point, Wi-Fi (wireless) connection with another access point by disabling the Wi-Fi (wireless) communication of the communication apparatus 100 As a result, 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 connection with the server 300.

Second Embodiment of the Present Invention
Next, a second embodiment of a 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 related to the original Service Set Identifier (SSID) and password currently set in the communication device 100 shown in FIG. Even when the Wi-Fi (wireless) connection between the communication device 100 and the information communication device 200 can not be set, the Wi-Fi (wireless) connection between the communication device 100 and the information communication device 200 is assured To make it possible to set the information on the connection destination in the wide area communication network of the communication apparatus 100, and at the same time, enable the information communication device 200 to make a Wi-Fi (wireless) connection with the communication apparatus 100. The case of automatically setting to the normal state is described. The system configuration of the wireless communication network system and the internal configuration 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 duplicates here are I will omit my explanation.

(Description 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 below with reference to the flowcharts of FIGS. 4A and 4B. The two drawings of FIG. 4A and FIG. 4B constitute one flow chart. It is difficult to draw an entire flow chart on a single sheet because it is difficult to limit the dimensions of the sheet, so the first half of the flow chart is depicted in FIG. 4A and the second half of the flowchart is depicted in FIG. And, A and B indicated by encircled at the lower end of FIG. 4A are respectively connected to A and B indicated by encircled at the upper end of FIG. 4B. That is, FIG. 4A and FIG. 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 can not be established, the user of the communication device 100 first operates The IF 104 is operated to temporarily change the original Service Set Identifier (SSID) and password currently set in the communication apparatus 100 to a known fixed SSID and password which are previously determined (step S21). Here, the communication apparatus 100 set to the fixed SSID and password is set in a state where the setting change of the communication apparatus 100 can not be performed from any external apparatus or device in consideration of security measures ((1) Step S22). That is, while in a state where the SSID and password of the communication device 100 are temporarily switched to the fixed SSID and password set in advance and set, wide area communication of the communication device 100 transmitted from the information communication device 200 is performed. It is set in a state in which reception of external information is completely prohibited except during a period of receiving information on the latest connection destination in the network.

  Next, the management unit 201 of the information communication device 200 performs Wi-Fi (wireless) connection with the communication apparatus 100 set to the fixed SSID and the password (step S23). Thereafter, the management unit 201 of the information communication device 200 performs the same operation as steps S2 to S6 in FIG. That is, first, the management unit 201 of the information communication device 200 selects, from the communication device 100, selection condition information required to acquire information on the connection destination in the wide area communication network of the communication device 100 (that is, the model of the communication device 100). (Step S24), the WAN communication IF 202 of the information communication device 200 confirms whether or not WAN communication with the server 300 is possible (step S24). S25), if possible (if Yes at step S26), based on the selection condition information required to obtain the information on the connection destination of the communication device 100 received from the communication device 100, The information (APN etc.) regarding an appropriate connection destination is selected and acquired from the APN list | wrist 301 of 300 (step S44).

  On the other hand, when the WAN communication IF 202 of the information communication device 200 can not communicate with the server 300 on the WAN side (No in step S26), the management unit 201 of the information communication device 200 temporarily In addition to the setting for disabling the Wi-Fi (wireless) communication with the communication device 100, the communication device 100 is requested to disable the Wi-Fi (wireless) communication (step S27). In addition, the control unit 101 of the communication apparatus 100 that has received the request for invalidation performs the same operation as steps S11 to S13 in FIG. 3. That is, when a request for temporary invalidation of Wi-Fi (wireless) communication is received from the information communication device 200 (step S28), the control unit 101 of the communication device 100 determines the Wi-Fi with the information communication device 200. The (wireless) communication is invalidated (step S29), and the time when the Wi-Fi (wireless) communication is invalidated is recorded (step S30).

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

  When the operation of step S30 is completed, the control unit 101 of the communication apparatus 100 performs the same operation as that of steps S14 to S17 of FIG. 3. That is, the control unit 101 of the communication apparatus 100 receives a user's instruction to enable Wi-Fi (wireless) communication via the operation IF 104, or a predetermined time (for example, 3 minutes) elapses in advance. Until waiting (step S32), there is a user's instruction (in the case of Yes in step S33), or when the predetermined time (for example 3 minutes) elapses (in the case of Yes in step S34), the LAN communication of the communication device 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 step S7 of FIG. 2 and performs Wi-Fi (wireless) connection with the communication apparatus 100 in which the fixed SSID is set (step S36).

  However, here, since the communication apparatus 100 is set in a state where setting can not be performed at all from an external device or apparatus in step S22, the management unit 201 of the information communication apparatus 200 sets a fixed SSID. In a state where it is possible to change the setting of the communication device 100 from the information communication device 200 which is an external device of the communication device 100 by operating the operation IF 104 of the communication device 100 with respect to the communication device 100 being The setting is requested (step S37). The control unit 101 of the communication device 100 that has received the request from the information communication device 200 displays the request on the screen and notifies the user of the communication device. The user who has visually recognized the notification performs an operation for permitting the setting of the communication apparatus 100 from the external information communication device 200 via the operation IF 104 (step S38).

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

  Next, when the information on the connection destination of the communication device 100 in the wide area communication network is set, the control unit 101 of the communication device 100 causes the information communication device 200 to obtain the original SSID before the change of the communication device 100. After notifying information on 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 on the original SSID and password of the communication device 100 transmitted from the communication device 100, the management unit 201 of the information communication device 200 returns to the original SSID and password. A connection profile for performing Wi-Fi (wireless) connection is created and stored (step S42).

  Furthermore, the control unit 101 of the communication apparatus 100 performs the same operation as step S19 in FIG. 3, and based on the set connection destination information, the wide area communication network such as the LTE network via the WAN communication IF 102. A connection with the Internet line 500 is made (step S43).

  As described above in detail, 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 does not hold the information. Even if the Wi-Fi (wireless) connection between the device and the information communication device 200 can not be set, the communication device 100 is temporarily changed to a predetermined fixed SSID and password which are determined in advance and set. By doing this, it is possible to securely make a Wi-Fi (wireless) connection between the communication device 100 and the information communication device 200. Since the operation of setting the information on the connection destination in the wide area communication network of the communication device 100 is enabled, and the information on the original SSID and password of the communication device 100 is received to create the connection profile, Thereafter, the information communication device 200 can also perform Wi-Fi (wireless) connection with the communication device 100.

  In addition, when changing to a fixed SSID and password and setting, except for a period in which the information communication device 200 performs an operation to set information related to the connection destination of the communication device 100, the external device or device does not By shifting to a state in which the setting for the communication apparatus 100 is completely prohibited, a security measure to prevent unauthorized access is also realized.

Third Embodiment of the Present Invention
Next, a third embodiment of a wireless communication network system according to the present invention will be described in detail with reference to the drawings. In the third embodiment, the wide area of the communication apparatus 100 is obtained using the information communication device 200A having the LAN communication IF 203 but not the WAN communication IF 202 instead of the information communication device 200 shown in FIG. A case where information on a connection destination in a communication network is set in the communication device 100 will be described. Even when the information communication device 200A according to the third embodiment includes the WAN communication IF 202, the information communication device 200A can not be used due to a failure or the like.

(Configuration Example of 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 is configured to include at least a communication device 100, an information communication device 200A, a server 300, and an access point 400. Here, although the communication apparatus 100 and the server 300 have the same internal configuration as in the case of FIG. 1, the information communication device 200A is an inside in which the WAN communication IF 202 is deleted from the information communication device 200 of FIG. It consists of composition.

  Further, the access point 400 shown in FIG. 5 is, for example, a device similar to a public wireless router device having a wireless relay function used in a public wireless LAN or the like, and information of connection destinations in a wide area communication network such as an LTE network It is internally held and is configured to include at least a WAN communication IF 402 and a LAN communication IF 403. Then, Wi-Fi (wireless) connection is established with the information communication device 200 not provided with the WAN communication IF, and data transmitted / received to / from the server 300 via the Internet line 500 meaning wide area communication network is transmitted to the information communication device. It is possible to relay to 200A.

(Description of the operation of the third embodiment of the present invention)
Next, an example of the operation in the wireless LAN network system shown in FIG. 5 as the third embodiment will be described in detail with reference to the flowchart of FIG. FIG. 6 is a flow chart showing an example of the operation of the wireless LAN network system shown in FIG. 5 as the third embodiment, wherein the information communication device 200A acquires the communication device 100 acquired from the server 300 via the access point 400. An example of operation until information on a connection destination is set in the communication device is shown. The operation of the control unit 101 of the communication apparatus 100 when the Wi-Fi (wireless) function of the communication apparatus 100 is disabled is the same as that of the flowchart of FIG. 3 in the first embodiment, The description here is omitted. The following description will be made focusing on differences from the flowchart of FIG. 2 of the first embodiment 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 IF 202, the information communication device 200A alone is an Internet line that means a wide area communication network. It is not possible to communicate via 500. Therefore, the information communication device 200A in the third embodiment searches as a access point 400, for example, a public wireless LAN router (public access point) used in a public wireless LAN or the like, and is detected as a search result. Using the wireless relay function using the LAN communication IF 403 and the WAN communication IF 402 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 IF 203 of the information communication device 200A and the LAN communication IF 403 of the access point 400 can connect via Wi-Fi (wirelessly) using the access point 400 as a parent device and the information communication device 200A as a child device. . Then, the access point 400 having the relay function can communicate with the Internet line 500 via the WAN communication IF 402. Therefore, the information communication device 200A can communicate with the Internet line 500, which means a wide area communication network, via the LAN communication IF 203, the LAN communication IF 403, and the WAN communication IF 402.

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

  As a result of the search, when the access point 400 can be detected, the information communication device 200A checks whether or not the Wi-Fi (wireless) connection with the access point 400 can be performed ( Step S57), if Wi-Fi (wireless) connection can not be performed (No in step S57), the process returns to step S56 and the Wi-Fi (wireless) connection can be performed , Search operation of another access point 400 is repeated.

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

  In the following step S59 and step S60, the same operation as step S7 and step S8 in FIG. 2 of the first embodiment is performed, and the management unit 201 of the information communication device 200A -Fi (wireless) connection is made (step S59), information (APN etc.) on the latest connection destination in the wide area communication network acquired from the server 300 in step S58 is transmitted to the communication apparatus 100, and the communication is performed 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 connected to the communication device 100 with Wi-Fi (wirelessly) does not have the WAN communication IF 202, a public wireless LAN or the like can be used. 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 on the connection destination in the wide area communication network of the communication apparatus 100.

  The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such an embodiment is merely an example of the present invention and does not limit the present invention. It will be readily understood by those skilled in the art that various modifications and variations can be made according to a particular application without departing from the scope of the present invention.
