First, a method of transmitting the wireless profile of the HGW 100 to the cloud server 200 will be described with reference to FIG. 7. FIG. 7 is a sequence diagram of the radio profile registration process.

The HGW 100 accesses the cloud server 200 when the power is turned on and the WAN (Wide Area Network) connection to the communication network 4 is established (S501). When accessing the cloud server 200, the HGW 100 notifies the cloud server 200 that the access is from the HGW 100. As a method of this notification, a message indicating that the access is from the HGW 100 may be transmitted to the packet at the time of access. When the cloud server 200 detects the access from the HGW 100, the cloud server 200 transmits the access permission to the HGW 100 (S502). The cloud server 200 requests the wireless profile information of the HGW 100 from the HGW 100 to which the access notification is sent (S503). The HGW 100 transmits wireless profile information to the cloud server 200 in response to a request from the cloud server 200 (S504). After receiving the wireless profile information, the cloud server 200 associates the MAC address of the HGW 100 with the wireless profile information and registers the wireless profile information in the profile management unit 220 (S505). Further, the HGW 100 transmits the user account information to the cloud server 200 (S506).

When the smart speaker 300 is connected to the HGW 100, the same user account information as the HGW 100 is transmitted to the cloud server 200 (S507). The cloud server 200 links the accounts of the HGW 100 and the smart speaker 300 from the transmitted account information (S508), and registers the account information transmitted from the HGW 100 in association with the wireless profile (S509). In this way, the user account information of the smart speaker and the user account information of the HGW are the same, and they are linked to each other.

Next, a method of connecting the wireless terminal 400 owned by the user to the HGW 100 will be described with reference to FIGS. 8, 9 and 10. As an example of the wireless terminal 400, a method of connecting a smartphone to the HGW 100 will be described.
FIG. 8 is a sequence diagram when the wireless terminal accesses the cloud server. The wireless terminal 400 accesses the cloud server 200 by using a mobile communication service or a mobile communication network provided by a mobile communication operator such as 3G (or 4G or the like) or LTE (Long Term Evolution) (S601). The cloud server 200 generates a keyword for user authentication when the wireless terminal 400 is connected (S602). Further, as shown in FIG. 6, the cloud server 200 manages the individual identification number of the wireless terminal 400 in association with a keyword. The cloud server 200 uses a mobile communication service or a mobile communication network provided by a mobile communication operator such as 3G (or 4G, etc.) or LTE (Long Term Evolution) for the wireless terminal 400 to use a keyword for user authentication. Transmit (S603). The wireless terminal 400 transmits or notifies the user of the keyword received from the cloud server 200 (S604). For example, when the wireless terminal 400 is a smartphone, the smartphone displays the keyword received from the cloud server 200 on the display.

Next, with reference to FIG. 9, a process of transmitting the profile of the home gateway (HGW) 100 to the wireless terminal by performing user authentication by voice exchange with the user will be described.
FIG. 9 is a sequence diagram of wireless profile transmission processing to the wireless terminal. The user 5 verbally informs the smart speaker 300 connected to the HGW 100 that he / she wants to connect the wireless terminal 400 to the HGW 100 (S701). For example, the user issues a message to the smart speaker 300, "Connect the smartphone to the home gateway." The smart speaker 300 transmits the voice data emitted by the user to the cloud server 200 (S702). The cloud server 200 analyzes the received voice data using a known voice recognition engine. When the cloud server 200 receives a message that the wireless terminal 400 wants to be connected to the HGW 100, the cloud server 200 identifies the HGW 100 having a connection request from the user information of the source smart speaker (S703). The cloud server 200 transmits voice data inquiring the user for a keyword for user authentication to the smart speaker 300 in order to identify the wireless terminal 400 that wants to connect to the HGW 100 (S704). For example, send voice data such as "Please tell me the keyword of the terminal you want to connect to the HGW." The smart speaker 300 converts the voice data received from the cloud server 200 into an analog signal and transmits the voice signal (S705). The user verbally responds to the voice signal inquiring about the keyword transmitted from the smart speaker 300 (S706). For example, when the keyword transmitted to the wireless terminal 400 owned by the user and displayed on the display of the wireless terminal 400 is "aaaaaa", the user issues the keyword "aaaaa" accordingly. The smart speaker 300 transmits voice data to the cloud server 200 (S707). The cloud server 200 uses a known voice recognition engine to analyze voice data and identify a wireless terminal 400 that matches a keyword that the user has responded to (S708). The cloud server 200 uses a mobile communication service or a mobile communication network provided by a mobile communication operator such as 3G (or 4G, etc.) or LTE (Long Term Evolution), and uses the HGW 100 for a wireless terminal 400 having a matching keyword. (S709).

Finally, the connection process of the wireless terminal to the HGW will be described with reference to FIG.
FIG. 10 is a flowchart showing the connection process of the wireless terminal. After receiving the wireless profile of the HGW 100 (S801), the wireless terminal 400 notifies the user to make a wireless connection (S802). For example, it notifies the user to press the connection button in the smartphone application. Following the notification of the wireless terminal 400, the user presses the connection button in the smartphone application to connect the wireless terminal 400 to the HGW 100 (S803). The wireless terminal 400 accesses the access point in the received profile and wirelessly connects with the HGW 100 (S804). After the wireless terminal 400 is connected to the HGW 100, the HGW 100 transmits to the cloud server 200 that the wireless terminal 400 is connected (S805). After receiving the MAC address of the wireless terminal 400, the cloud server 200 transmits voice data indicating that the wireless terminal 400 has been successfully connected to the smart speaker 300 (S806). For example, the voice data "The smartphone was able to connect to the HGW100 normally" is transmitted. The smart speaker 300 converts the voice data transmitted from the cloud server 200 into an analog signal and transmits the voice signal.

When the user wants to connect a plurality of wireless terminals 400 at the same time, the cloud server 200 transmits voice data notifying that the connection was successful, and then transmits voice data confirming whether to connect another wireless terminal 400. You may. For example, the cloud server 200 transmits voice data indicating that the wireless terminal 400 has been successfully connected (S806), and then transmits voice data "Do you want to connect another wireless terminal?" To the smart speaker 300. To do. At this time, if the user verbally informs that another wireless terminal will be connected (for example, if the user answers "yes" to the question of whether to connect another wireless terminal), FIG. 9 shows. As described above, the voice data for inquiring the keyword again is transmitted to the smart speaker 300 (S704).

Alternatively, when the user is asked for a keyword and responds (S706), a plurality of keywords may be transmitted in one response. For example, when the keyword of the first wireless terminal 400 is "aaaaa" and the keyword of the second wireless terminal 400 is "bbbbbb", the user may answer "aaaaa and bbbbb" when answering the keywords. At this time, when the cloud server 200 analyzes the voice data, it recognizes that there are two keywords, identifies the wireless terminal 400 that matches each keyword (S708), and wirelessly attaches the HGW 100 to each wireless terminal 400. The profile is transmitted (S709).

The effect of the wireless connection system according to the present embodiment described above will be described. According to this embodiment, the wireless connection can be performed without the need to prepare the information necessary for the wireless connection in advance. In addition, even people who have no knowledge of wireless can easily set wireless. Wireless connection of many IoT devices can be easily made. Even if you want to connect multiple wireless terminals at the same time, you can do it with a single voice operation. It is possible to prevent a wireless terminal that is not intended by the user from connecting to the HGW device. A wireless connection can be easily made even with a wireless terminal that does not support WPS.

(S904).

The user informs the smart speaker 300 connected to the HGW 100 that he / she wants to connect the wireless terminal 400 to the HGW 100 (S905). For example, the smart speaker 300 says "I want to connect a smartphone to a home gateway." The smart speaker 300 transmits the voice data emitted by the user to the cloud server 200 (S906). The cloud server 200 manages the received voice data as shown in FIG. 13 in the profile management unit 220 in association with the wireless profile of the HGW (S907). The cloud server 200 recognizes the speaker from the voice data transmitted from the smart speaker 300 and the voice data transmitted from the wireless terminal 400 (S908).
