Description

The present invention relates to a wireless connection system, a relay device, and a wireless connection method.

In recent years, with the spread of IoT (Internet of Things) devices, the number of devices connected to a home gateway (hereinafter abbreviated as HGW) is increasing. In order to wirelessly connect an IoT device, it is necessary to prepare HGW wireless profile information and perform wireless connection according to the procedure for each device.

However, it is often difficult for people without knowledge of wireless to prepare wireless profile information for wirelessly connecting an IoT device to an HGW. Therefore, there is a problem that such people cannot easily establish a wireless connection.

As a method for connecting an IoT device to the Internet, there is a method of connecting the device to an HGW and connecting to the Internet via the HGW.

As a method of connecting the IoT device to the HGW, there is a wireless connection method of connecting the IoT device and the HGW using a wireless function such as Wi-Fi (registered trademark). In order to establish a wireless connection, it is necessary to prepare in advance information necessary for wireless connection, such as the SSID (Service Set Identifier) of the access point and an encryption key. However, it is not easy for a user who has no knowledge of wireless settings to prepare the SSID and encryption key and connect the wireless terminal to the HGW.

There is a method called WPS (Wi-Fi (registered trademark) Protected Setup) connection as a method for wireless connection without requiring the input of the SSID of the access point to be connected, the encryption key, or the like. In the WPS connection, pressing a button mounted on the HGW device activates the WPS function and executes the WPS connection. However, in the WPS connection, it is necessary to activate the WPS function as many times as the number of terminals to be connected. If the number of wireless terminals to be connected to the HGW device increases at the same time, the burden of user operations increases. Also, when the HGW device starts WPS connection, if a wireless terminal unintended by the user is in a WPS connection waiting state near the access point, the wireless terminal unintended by the user may be connected to the HGW device. be.

In addition, as means for transmitting wireless profile information to a wireless terminal to be connected to the HGW device, in Patent Document 1, the HGW and the wireless terminal are connected by a method different from the wireless communication method to be connected (for example, USB (Universal Serial Bus)). ) or wired connection using a LAN (Local Area Network) cable or the like) to facilitate setting for wireless communication.

JP 2016-167702 A

However, in this method, the user needs to connect the HGW and the wireless terminal by wire once, and if the user can make the wired connection, it is possible to easily perform settings for wireless communication. However, wireless terminals that do not have a wired connection method, i.e., a method other than wireless connection, cannot use this method. do not have.

Further, when connecting with a wireless communication method different from the desired wireless communication method, the user needs to input the SSID, encryption key, etc., and connect the HGW and the wireless terminal once. Therefore, wireless connection is not easy for those who have no knowledge of wireless.

When the HGW 100 is powered on and a WAN (Wide Area Network) connection to the communication network 4 is established, the HGW 100 accesses the cloud server 200 (S501). The HGW 100 notifies the cloud server 200 that the access is from the HGW 100 when accessing the cloud server 200 . As a method of this notification, a message indicating that the access is from the HGW 100 may be transmitted in the access packet. When the cloud server 200 detects access from the HGW 100, it transmits access permission to the HGW 100 (S502). Cloud server 200 requests wireless profile information of HGW 100 from HGW 100 to which the access notification has been sent (S503). The HGW 100 transmits the wireless profile information to the cloud server 200 in response to the 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 them in the profile management unit 220 as shown in FIG. 5 (S505). Also, 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, it transmits the same user account information as the HGW 100 to the cloud server 200 (S507). Cloud server 200 links the accounts of HGW 100 and smart speaker 300 from the transmitted account information (S508), and registers the account information transmitted from HGW 100 in association with the wireless profile (S509). Thus, the smart speaker user account information and the HGW user account information are the same and are linked together.

Next, a method for connecting the wireless terminal 400 owned by the user to the HGW 100 will be described with reference to FIGS. As an example of the wireless terminal 400, a method of connecting a smart phone 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 using a mobile communication service or mobile communication network such as 3G (or 4G) or LTE (Long Term Evolution) provided by a mobile communication service provider (S601). The cloud server 200 generates a keyword for user authentication when the wireless terminal 400 is connected (S602). Furthermore, as shown in FIG. 6, the cloud server 200 associates and manages the individual identification number of the wireless terminal 400 and the keyword. The cloud server 200 sends a keyword for user authentication to the wireless terminal 400 using a mobile communication service or a mobile communication network such as 3G (or 4G) or LTE (Long Term Evolution) provided by a mobile communication carrier. Send (S603). The wireless terminal 400 transmits or notifies the user of the keyword received from the cloud server 200 (S604). For example, if wireless terminal 400 is a smartphone, the smartphone displays the keyword received from cloud server 200 on its display.

Next, with reference to FIG. 9, a process of transmitting the profile of the home gateway (HGW) 100 to the wireless terminal by authenticating the user through voice communication with the user will be described.
FIG. 9 is a sequence diagram of wireless profile transmission processing to a wireless terminal. The user 5 orally informs the smart speaker 300 connected to the HGW 100 that he/she wishes to connect the wireless terminal 400 to the HGW 100 (S701). For example, the user speaks to smart speaker 300, "connect smart phone to home gateway". The smart speaker 300 transmits voice data uttered by the user to the cloud server 200 (S702). Cloud server 200 analyzes the received voice data using a known voice recognition engine. When the cloud server 200 receives the request to connect the wireless terminal 400 to the HGW 100, it identifies the HGW 100 requesting the connection from the user information of the smart speaker that is the transmission source (S703). In order to specify the wireless terminal 400 to be connected to the HGW 100, the cloud server 200 transmits voice data asking the user for a keyword for user authentication to the smart speaker 300 (S704). For example, it transmits voice data saying "Please tell me the keyword of the terminal you want to connect to the HGW." The smart speaker 300 converts the audio data received from the cloud server 200 into an analog signal and transmits the audio signal (S705). The user verbally responds to the voice signal inquiring about the keyword transmitted from the smart speaker 300 (S706). For example, if the keyword sent to the wireless terminal 400 carried by the user and displayed on the display of the wireless terminal 400 is "aaaaa", the user accordingly utters the keyword "aaaaa". The smart speaker 300 transmits the audio data to the cloud server 200 (S707). Cloud server 200 analyzes the voice data using a known voice recognition engine, and identifies wireless terminal 400 that matches the keyword responded by the user (S708). The cloud server 200 uses mobile communication services or mobile communication networks such as 3G (or 4G, etc.) and LTE (Long Term Evolution) provided by mobile communication providers to provide HGW 100 to wireless terminals 400 with matching keywords. wireless profile is transmitted (S709).

Finally, with reference to FIG. 10, the process of connecting the wireless terminal to the HGW will be described.
FIG. 10 is a flowchart showing connection processing of a wireless terminal. After receiving the wireless profile of the HGW 100 (S801), the wireless terminal 400 notifies the user to perform wireless connection (S802). For example, a smartphone application notifies the user to press a connection button. Following the notification from the wireless terminal 400, the user presses the connection button on 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 notifies the cloud server 200 that the wireless terminal 400 has been 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 successfully connected to the smart speaker 300 (S806). For example, the voice data saying "The smart phone was successfully connected to the HGW 100" is transmitted. The smart speaker 300 converts the audio data transmitted from the cloud server 200 into an analog signal and transmits the audio signal.

When the user wants to connect multiple wireless terminals 400 at the same time, the cloud server 200 transmits voice data indicating that the connection has been made normally, and then transmits voice data confirming whether to connect another wireless terminal 400. can be For example, after the cloud server 200 transmits voice data indicating that the wireless terminal 400 has been successfully connected (S806), the cloud server 200 transmits to the smart speaker 300 voice data saying "Would you like to connect another wireless terminal?" do. At this time, if the user verbally informs that another wireless terminal will also be connected (for example, if the user answers "yes" to the question whether to connect another wireless terminal), the As described above, the voice data asking for the keyword again is transmitted to the smart speaker 300 (S704).

Alternatively, when the user is asked about keywords and responds (S706), a plurality of keywords may be given 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 "bbbbb", 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, specifies the wireless terminals 400 that match each keyword (S708), Send the profile (S709).
