  Here, an example in which a plurality of sets of setting information is stored in the setting information 121 has been described. However, only one set of setting information may be stored in the setting information 121.

[Signal format]
FIG. 3 is a diagram showing an example of a signal format used for short-range wireless communication and wireless network communication in the embodiment of the present invention.

  The short-range wireless communication unit 130 of the communication terminal 100 transmits a BLE packet 710 according to the BLE standard as a link layer packet. The BLE packet 710 includes a 1-octet preamble 711, a 4-octet access address 712, a 2- to 39-octet PDU (Protocol Data Unit), and a 3-octet CRC (Cyclic Redundancy Check) 715.

  The preamble 711 is a signal added to the head of the packet for frequency synchronization, symbol timing estimation, and AGC adjustment on the receiving side. The access address 712 is a physical address used as a correlation code for matching with a physical channel. CRC 715 is a cyclic redundancy check code for detecting an error that has occurred in the course of communication.

  The short-range wireless communication unit 230 of the wireless communication device 200 receives the BLE packet 710 transmitted from the communication terminal 100. Then, the network communication unit 240 of the wireless communication device 200 converts the BLE packet 710 into a wireless network communication protocol and transmits it to the access point 300. In this embodiment, IEEE802.11 is assumed as a wireless network communication protocol, and the network communication unit 240 transmits a PLCP (Physical Layer Convergence Protocol) frame 720.

  The PLCP frame 720 includes a PLCP (Physical Layer Convergence Protocol) preamble 721, a PLCP header 722, and a PSDU (PLCP Service Data Unit). The PLCP preamble 721 is a bit string of a synchronization signal added to the head of the PLCP frame 720. The PLCP header 722 includes information such as a modulation scheme and a data length. A MAC (Media Access Control) frame is stored in PSDU that is data of the PLCP frame 720.

Thereby, the network communication unit 240 of the wireless communication device 200 tries to connect to the access point 300 by including the setting information in the data 724 of the PLCP frame 720. The processing unit 110 of the communication terminal 100 receives notification of the result of the connection attempt from the processing unit 210 of the wireless communication device 200, and as a result, a wireless network connection is established between the access point 300 and the wireless communication device 200. In such a case, the processing unit 110 of the communication terminal 100 instructs the processing unit 210 of the wireless communication device 200 to store the setting information at that time in the storage unit 220.

  As processing when the processing unit 110 of the communication terminal 100 instructs the processing unit 210 of the wireless communication device 200 to try to connect to the access point 300, for example, the setting information is transmitted by the payload 714 of the BLE packet 710. It is also possible to transmit a connection trial program including the program and execute the program in the processing unit 210 in the wireless communication device 200.

  As another example of processing for instructing an operation to try to connect to the access point 300, the processing unit 110 of the communication terminal 100 generates a control signal for requesting connection to the access point 300, and BLE. By transmitting by the payload 714 of the packet 710, the control signal including the setting information is transmitted to the wireless communication device 200. The processing unit 210 on the wireless communication device 200 side may directly convert the contents of the payload 714 received through the short-range wireless communication unit 230 into data 724 and supply the data 724 to the network communication unit 240.

An instruction to perform is given (step S912). The processing unit 110 receives the notification of the result of the connection attempt at this time, analyzes the content, and when the wireless network connection is established between the access point 300 and the wireless communication device 200 (step S913: Yes), the processing unit 110 of the communication terminal 100 instructs the processing unit 210 of the wireless communication device 200 to store the setting information at that time in the storage unit 220 (step S916).

  On the other hand, when the wireless network connection is not established (step S913: No), if the setting information of the untrial is stored in the storage unit 120 (step S914: Yes), the setting information is included in the payload 714. (Step S915) Transmit and instruct the processing unit 210 of the wireless communication device 200 to try to connect to the access point 300 (Step S912). If there is no setting information that can be connected to the access point 300 (step S914: No), the connection trial process ends in an error.

  When the communication terminal 100 and the wireless communication device 200 enter a range in which communication by near field communication is possible, communication by near field communication is started (step S811). The communication terminal 100 transmits the setting information and the command to the wireless communication device 200 and instructs to try to connect to the access point 300 (step S812). Accordingly, the wireless communication device 200 requests connection to the access point 300 (step S813).

  In response to a connection request from the wireless communication device 200, authentication processing of setting information is performed with the access point 300 (step S814). Specifically, it is a requirement necessary for authentication that the SSID of the setting information matches the SSID of the access point 300, and that the encryption format and the encryption key match those assumed in the access point 300. Become.

  If the authentication is successful, connection between the wireless communication device 200 and the access point 300 is established, and connection for wireless network communication is started (step S815). When this connection is established, the wireless communication device 200 notifies the communication terminal 100 to that effect (step S816).

  Upon receiving a connection establishment notification from the wireless communication device 200, the communication terminal 100 instructs the wireless communication device 200 to store the setting information used for the connection in the storage unit 220 (step S817). As a result, the setting information used for the established connection is stored as the setting information 221 in the storage unit 220.

  As described above, in the embodiment of the present invention, the communication terminal 100 sets the setting information for connecting to the access point 300 of the wireless network for the small-scale wireless communication device 200 having no wireless network setting function. Let Thereby, the setting for connecting the wireless communication device 200 to the access point 300 of the wireless network can be performed.
