1A to 3 are diagrams for explaining registration of a WiFi device according to an embodiment.

Referring to FIG. 1A , a WiFi device 110 , an access point (AP) 120 , and a server 130 are shown.

The WiFi device 110 is a device capable of WiFi communication, and may correspond to, for example, an Internet of Thing (IoT) device. As an example, the WiFi device 110 may include, but is not limited to, a smart home appliance or a smart home device capable of WiFi communication.

A user may subscribe to the WiFi device 110 in order to use the WiFi device 110 . The server 130 stores information of the WiFi device 110 in the device database. The information of the WiFi device 110 may include, for example, at least one of a type of the WiFi device 110 , a MAC (Medium Access Control) address, a serial number, and a model name, but is not limited thereto.

The AP 120 provides a hidden Service Set Identifier (SSID) for a predetermined time. As will be described later, the AP 120 also provides an SSID for a service purpose (or service access). Here, the service may be, for example, an IoT service, but is not limited thereto. The SSID for service use is separated or separated from the hidden SSID.

The WiFi device 110 stores the hidden SSID of the AP 120 in advance, and the WiFi device 110 can access the AP 120 based on the hidden SSID. When the WiFi device 110 accesses through the hidden SSID, the AP 120 transmits AP information (or AP connection information) to the WiFi device 110 through server authentication. The AP information may include, for example, an SSID for service provision of the AP 120 , a password, a WiFi encryption method, and the like. The WiFi device 110 may use the AP information received from the AP 120 to access the AP 120 and perform server registration.

According to an embodiment, the hidden SSID can be operated only on the AP 120 designated by the user, so that the WiFi device 110 can be attached to the desired AP 120 , and the AP 120 is a WiFi device authenticated through server authentication. You can only allow access. Also, the AP 120 may transmit the corresponding AP information to the WiFi device 110 without storing the AP information in the server 130 . Accordingly, the WiFi device 110 can access the AP 120 even if the user does not input AP information into the WiFi device 110 . Hereinafter, it will be described in detail with reference to FIG. 1B.

Referring to FIG. 1B , the AP 120 may drive (or activate) the hidden SSID ( 140 ). For example, when the user presses a specific button of the AP 120 , the AP 120 may drive (or activate) the hidden SSID “1234”. The specific button may be, for example, a WPS button, but is not limited thereto. Previously, the hidden SSID was exemplified as “1234”, but this is only an example, and the hidden SSID of the AP 120 is not limited to “1234”.

The hidden SSID does not appear normally, but appears or operates for a certain period of time when the user presses a specific button of the AP 120 . The predetermined time may be, for example, a timeout time of the WPS, but is not limited thereto.

AP 120 may open a pairing port (141). The AP 120 has a daemon process for pairing (in other words, a pairing daemon), and when the hidden SSID operates, the AP 120 may open a pairing port.

The WiFi device 110 may access the AP 120 with a hidden SSID (142). For example, when the WiFi device 110 is powered on and booted, it may check whether an SSID for a service is stored in its memory. If the SSID for the service purpose is stored, the WiFi device 110 may perform a WiFi access procedure with the corresponding SSID. If the SSID for the service is not stored, the WiFi device 110 may scan a predefined hidden SSID “1234” in its memory and access it using a password for the hidden SSID “1234”. In other words, the WiFi device 110 may perform scanning based on the hidden SSID "1234" and discover the AP 120 according to the scanning, and may use the hidden SSID "1234" and password to scan the AP 120 can connect to Since the hidden SSID “1234” is operated or activated in the AP 120 , the AP 120 may allow an access request attempted by the WiFi device 110 through the hidden SSID “1234”. The WiFi device 110 may access an open pairing port.

Since the WiFi device 110 is not yet registered with the server 130 on the application of the user's terminal, the WiFi device 110 cannot be remotely controlled. As will be described later, the WiFi device 110 is registered with the server 130 , and accordingly, the user can remotely control the WiFi device 110 through an application of the terminal.

The WiFi device 110 may request AP information from the AP 120 (143). In step 143 , the WiFi device 110 may transmit its information to the AP 120 . The information of the WiFi device 110 may include, for example, one or more of a type, a MAC address, a serial number, and a model name.

The AP 120 may request authentication for the WiFi device 110 from the server 130 ( 144 ). For example, the pairing daemon of the AP 120 may request authentication for the WiFi device 110 from the server 130 while transmitting information of the WiFi device 110 to the server 130 .

The server 130 may perform authentication for the WiFi device 110 (145). For example, the server 130 may check whether the WiFi device 110 information received from the AP 120 is stored in the device database 130-1. In other words, the server 130 may check whether the WiFi device 110 corresponds to the WiFi device subscribed to by the user through the WiFi device 110 information. Here, when the WiFi device 110 information is stored in the device database 130-1, the server 130 may determine that the authentication of the WiFi device 110 is successful. If, the server 130 does not store the WiFi device 110 information in the device database 130-1, it may determine that the authentication of the WiFi device 110 has failed.

The server 130 may transmit the authentication result for the WiFi device 110 to the AP 120 (146). As an example, the server 130 may transmit authentication success or authentication failure for the WiFi device 110 to the pairing daemon of the AP 120 .

The AP 120 may check the server authentication result ( 147 ), and if the server authentication result is authentication success, the AP 120 may transmit AP information to the WiFi device 110 ( 148 ). As an example, the pairing daemon of the AP 120 may read the SSID, password, and WiFi encryption method of the service purpose of the AP 120 when the authentication result received from the server 130 indicates authentication success, and the pairing port The SSID for the service use of the AP 120 , the password, and the WiFi encryption method may be transmitted to the WiFi device 110 connected to the . The WiFi encryption method may be, for example, Wired Equivalent Policy (WEP), WiFi Protected Access (WPA), WPA 2, and the like, but is not limited thereto.

The AP 120 may close the pairing port (149) and terminate (or disable) the hidden SSID (150).

The WiFi device 110 may access the AP 120 by using the AP information received from the AP 120 (151). For example, the WiFi device 110 may transmit a probe request frame including an SSID for a service to the AP 120 , and may receive a probe response frame from the AP 120 . Thereafter, the WiFi device 110 may access the AP 120 by performing an authentication procedure and an association procedure with the AP 120 .

The WiFi device 110 may store AP information received from the AP 120 in a memory. Accordingly, the WiFi device 110 can access the AP 120 by using the AP information stored in the memory even if the connection with the AP 120 is cut due to some factor (eg, booting, etc.).

The WiFi device 110 may register with the server 130 (152). For example, since the WiFi device 110 is connected to the AP 120 , it can access the server 130 through a network and register the WiFi device 110 itself with the server 130 .

When the WiFi device 110 is registered, the server 130 may transmit a push message to the application of the user's terminal ( 153 ). Since the WiFi device 110 is in a registered state on the application, the user can remotely control the WiFi device 110 .

An example of step 145 is shown in FIG. 2 .

Referring to the example shown in FIG. 2 , the server 130 may receive an authentication request for the WiFi device 110 from the AP 120 ( 210 ). For example, the server 130 may receive the WiFi device 110 information and the AP 120 information from the AP 120 . As described above, the WiFi device 110 information may include, for example, at least one of a type, a MAC address, a serial number, and a model name of the WiFi device 110 . The AP 120 information may include, for example, at least one of a MAC address, a serial number, and a model name of the AP 120 .

The server 130 may check whether the WiFi device 110 information is stored ( 220 ), and check whether the WiFi device 110 and the AP 120 are mapped ( 230 ). As an example, the server 130 may check whether the WiFi device 110 information is stored in the device DB 130-1, and the WiFi device 110 information and the AP 120 on the device DB 130-1. You can check whether the information is mapped or not.

The server 130 may transmit the authentication result based on the steps 220 and 230 to the AP 120 (240). For example, when the WiFi device 110 information is stored in the device DB 130-1 and the WiFi device 110 and the AP 120 are mapped to each other, the server 130 transmits authentication success to the AP 120. can be sent to The server 130 detects an authentication failure when the WiFi device 110 information is not stored in the device DB 130-1 and/or when the WiFi device 110 and the AP 120 are not mapped to each other. It can be transmitted to the AP (120).

In the case of the example shown in FIG. 2 , the server 130 may prevent the WiFi device 110 from accessing another AP by checking whether the AP 120 and the WiFi device 110 are mapped to each other.

An example of step 142 is shown in FIG. 3 .

Referring to the example shown in FIG. 3 , the WiFi device 110 may transmit a probe request frame to the AP 120 ( 310 ). In this case, the probe request frame may include, for example, an SSID previously stored in the WiFi device 110 .

The AP 120 may transmit a probe response frame to the WiFi device 110 ( 320 ). For example, the AP 120 may transmit the probe response frame to the WiFi device 110 because its hidden SSID is the same as the SSID included in the received probe request frame. According to an embodiment, the AP 120 may calculate a signal strength value (eg, received signal strength indication (RSSI)) of the probe request frame. The AP 120 may not transmit the probe response frame to the WiFi device 110 when the calculated signal strength value is less than a predetermined strength value, and transmits the probe response frame to the WiFi device ( 110) can be transmitted. This is only an example, and even if the calculated signal strength value is less than a predetermined strength value, the AP 120 may transmit a probe response frame to the WiFi device 110 .

The WiFi device 110 may perform an association procedure with the AP 120 ( 330 ). In step 330 , the WiFi device 110 may transmit an association request frame to the AP 120 and receive an association response frame from the AP 120 . According to an embodiment, the WiFi device 110 may calculate a signal strength value of the probe response frame. The WiFi device 110 may not transmit the association request frame to the AP 120 if the calculated signal strength value is less than a predetermined strength value, and transmits the association request frame to the AP 120 if the calculated signal strength value is greater than or equal to the predetermined strength value ) can be transmitted. This is only an example, and even if the calculated signal strength value is less than a predetermined strength value, the WiFi device 110 may transmit the association request frame to the AP 120 .

In the case of the example shown in FIG. 3 , the WiFi device 110 and the AP 120 may prevent the WiFi device 110 from accessing another AP by checking whether they are close to each other.

4 to 5 are diagrams for explaining registration and remote control of a WiFi device according to an embodiment.

Referring to FIG. 4 , the AP 120 is connected to each of the WiFi device 1 410 , the WiFi device 2 420 , and the WiFi device 3 410 . The user may control each of the WiFi device 1 410 , the WiFi device 2 420 , and the WiFi device 3 410 through the application of the user's terminal 440 . The terminal 440 may be, for example, a smartphone or a tablet PC, but is not limited thereto.

A user may purchase the WiFi device 110 and try to connect it with the AP 120 . A user may place the WiFi device 110 within the coverage 400 of the AP 120 and turn on the WiFi device 110 . Even if the user does not input AP connection information to the WiFi device 110 , the WiFi device 110 may be automatically connected to the AP 120 . 5 , the WiFi device 110 may be connected to the AP 120 and may be registered with the server 130 . The user may control the WiFi device 110 through the application of the terminal 440 .

6 is a flowchart illustrating a method of operating a wireless network device according to an embodiment.

The wireless network device to be described with reference to FIG. 6 may correspond to the AP 120 , and the communication device may correspond to the WiFi device 110 .

Referring to FIG. 6 , the wireless network device activates a first identifier of the wireless network device based on a user input to the wireless network device itself ( 610 ). Here, the user input may indicate an input for a specific button (eg, a WPS button) of the wireless network device, and the first identifier of the wireless network device may correspond to a hidden SSID.

The wireless network device performs a first access procedure with the communication device storing the first identifier of the wireless network device ( 620 ).

As an example of step 620 , the wireless network device may receive a probe request frame from the communication device, and transmit a probe response frame to the communication device when an identifier in the received probe request frame is the same as the activated first identifier. . For example, the wireless network device may receive a probe request frame from the communication device while the hidden SSID “1234” is activated. At this time, if the identifier in the received probe request frame is “1234”, the wireless network device may transmit the probe response frame to the communication device. If the identifier in the received probe request frame is not “1234”, the wireless network device transmits the probe response frame to the communication device. may not After the communication device receives the probe response frame from the wireless network device, the communication device and the wireless network device may perform an association procedure.

As another example of step 620, when the identifier in the probe request frame received from the communication device is the same as the activated first identifier and the signal strength of the corresponding probe request frame is equal to or greater than a predetermined strength, the wireless network device communicates the probe response frame can be sent to the device. After the communication device receives the probe response frame, the communication device and the wireless network device may perform an association procedure.

The communication device may transmit the association request frame to the wireless network device when the signal strength of the probe response frame is equal to or greater than a predetermined strength. When receiving the association request frame from the communication device, the wireless network device may transmit an association response frame to the communication device.

As another example of step 620, when the identifier in the probe request frame received from the communication device is the same as the activated first identifier and the signal strength of the probe request frame is equal to or greater than a predetermined strength, the wireless network device communicates the probe response frame can be sent to the device. The communication device may transmit the association request frame to the wireless network device when the signal strength of the probe response frame is equal to or greater than a predetermined strength. When receiving the association request frame from the communication device, the wireless network device may transmit an association response frame to the communication device.

When the communication device accesses the wireless network device, the wireless network device receives device information of the communication device from the communication device ( 630 ). The device information of the communication device may include, for example, a MAC address and a serial number of the communication device.

The wireless network device transmits device information of the communication device to the server 130 to request authentication for the communication device from the server 130 ( 640 ). The server 130 may authenticate the communication device through whether device information of the communication device is registered or stored in the device DB 130-1. In an embodiment, the wireless network device may transmit its own device information and device information of the communication device to the server 130 . The device information of the wireless network device itself may include, for example, a MAC address and serial number of the wireless network device. The server 130 may check whether device information of the communication device is registered or stored, and may check whether device information of the communication device and device information of the wireless network device are mapped to each other. In other words, the server 130 may authenticate the communication device based on whether device information of the communication device is registered or stored and whether the communication device and the wireless network device are mapped to each other.

When the wireless network device receives a result indicating that authentication for the communication device is successful from the server 130, it transmits access information including the second identifier of the wireless network device to the communication device (650). Here, the second identifier of the wireless network device may correspond to an SSID for a service purpose. The access information may further include a password corresponding to the second identifier and a WiFi encryption method.

The wireless network device performs a second access procedure with the communication device based on the access information to connect with the communication device ( 660 ). Since the description of the step 151 may be applied to the description of the step 660 , a detailed description of the step 660 will be omitted.
