Description

[0001] Embodiments disclosed in this document relate to electronic devices and methods of operating electronic devices.

[0002] With the development of Internet of Things (IoT) technology, users can remotely control various types of IoT devices (e.g., smart TVs, air purifiers, air conditioners, refrigerators, or washing machines) through control devices (e.g., smartphones). User devices and IoT devices can communicate data using short-range wireless communication technologies (e.g., Bluetooth, near field communication (NFC)) and can be connected to an IoT server through an access point (AP) to form a local area network (LAN) (e.g., a WiFi network). IoT devices can use multiple networks, and network identifiers (e.g., service set identifiers (SSIDs)) and network passwords can be used for each network to connect to the network.

[0003] If the location of an IoT device changes (e.g., the device is moved to a location where it cannot receive signals from the AP) or the access point (AP) changes (e.g., network connection information changes), the IoT device may perform a procedure to reconnect to the AP. In this regard, if multiple IoT devices exist within an IoT environment, each electronic device must individually reconnect to the network.

For example, the IoT device (210) can include a user device (e.g., a smartphone, a tablet PC, a wearable device).

[0071] According to one embodiment, the AP (230) may include a device that enables devices to connect using a related standard using Wi-Fi in a computer network.

[0072] In one embodiment, the AP (230) can relay data between a wireless device and a wired device on a network. However, this is not limited to this, and the AP (230) can also relay data between wired devices or between wireless devices. Meanwhile, the AP (230) may also be referred to as a relay device.

[0073] According to one embodiment, the AP (230) can connect an IoT device (210), a control device (220), and an IoT server (240).

[0074] According to one embodiment, the AP (230) can transmit data received from the IoT server (240) to the IoT device (210) and / or the control device (220). In addition, the AP (230) can transmit data received from the IoT device (210) and / or the control device (220) to the IoT server (240).

[0075] According to one embodiment, the AP (230) may broadcast a reference signal (e.g., a beacon frame) according to a predetermined cycle.

[0076] According to one embodiment, when the AP (230) receives a connection request from the IoT device (210), it may connect the IoT device (210) and the IoT server (240) based on network connection information (e.g., network identifier, and / or network password) included in the connection request.

[0077] Figure 3 illustrates the signaling flow of devices in a network environment according to one embodiment.

[0078] According to one embodiment, in operation 302, the AP (230) may transmit a signal to the control device (220) and the IoT device (210). For example, the AP (230) may transmit a signal received from the IoT server (240) to the control device (220) and the IoT device (210).

[0079] According to one embodiment, the AP (230) can broadcast a reference signal. The reference signal can include a beacon frame. For example, the IoT device (210) and the control device (220) can scan the beacon frame broadcast from the AP (230). Although not shown in the drawing, the network environment (200) can include a plurality of APs (e.g., APs (230)). The IoT device (210) and the control device (220) can identify the strength of the reference signal detected through scanning and perform a connection with the AP (e.g., AP (230)) having the strongest signal strength in priority.

[0080] According to one embodiment, the IoT device (210) may transmit a probe request frame to the AP (230), and the AP (230) may receive a probe response frame in response thereto.

[0081] According to one embodiment, the control device (220) and the IoT device (210) can scan the reference signal received from the AP (230) to identify the presence of the AP (230) and request a connection with the AP (230). In the following description, the IoT device (210) and the AP (230) are described as having been previously connected, but this is only an example, and the embodiments of the present disclosure can be applied even when the IoT device (210) has never been connected to a network (e.g., the second network (199) of FIG. 1) via the AP (230).

[0082] In one embodiment, the reference signal may include a signal that the IoT device (210) transmits to adjacent devices based on a predetermined period. For example, the reference signal may include a beacon frame.

[0083] According to one embodiment, the AP (230) can transmit a reference signal to the IoT device (210) and / or the control device (220) through a broadcast method.

[0084] According to one embodiment, the reference signal may include connection information between the AP (230) and the IoT device (210). The IoT device (210) may identify that the reference signal is transmitted from the AP (230) based on the connection information between the AP (230) and the IoT device (210).

[0085] According to one embodiment, the reference signal may include a beacon response frame transmitted by the IoT device (210) in response to a request. For example, the IoT device (210) may transmit a probe request frame to connect to a network. The AP (230) that receives the probe request frame from the IoT device (210) may transmit a probe response frame to the IoT device (210).

[0086] According to one embodiment, the control device (220) may transmit a fourth packet to the IoT device (210) to notify a change in network connection information. In response to receiving the fourth packet, the IoT device (210) may transmit a first packet to the control device (220). The fourth packet may include an indicator notifying a change in network connection information.

[0087] According to one embodiment, the IoT device (210) can measure the strength of a reference signal broadcast from the AP (230). For example, the IoT device (210) can measure the received signal strength indicator (RSSI) of the reference signal.

[0088] According to one embodiment, in operation 304, the IoT device (210) may monitor whether the strength of the reference signal (e.g., RSSI) is below a predetermined value.

[0089] In one embodiment, the IoT device (210) may monitor whether reconnection with the AP (230) is required. The IoT device (210) may determine that reconnection with the AP (230) is required when it does not receive a signal from the AP (230) (e.g., when a reference signal is not received for a predetermined period of time) or when the strength of a signal received from the AP (230) is below a predetermined value (e.g., when the strength of a received reference signal is below a predetermined value).

[0090] According to one embodiment, the IoT device (210) may identify that the strength of a signal received from the AP (230) is below a first threshold value. If the location of the AP (230) or the IoT device (210) changes to a location where they cannot exchange signals with each other, or if the AP (230) changes (e.g., network connection information changes), the IoT device (210) may not be able to receive a reference signal from the AP (230). Alternatively, the strength of a signal received by the IoT device (210) from the AP (230) may decrease below a predetermined value.

[0091] According to one embodiment, the IoT device (210) may determine that reconnection with the AP (230) is necessary if it does not receive a reference signal from the AP (230) for a predetermined period of time or longer (including if the time for which the strength of the reference signal remains below a predetermined value is a predetermined period of time or longer). Since there is no need to perform reconnection between the AP (230) and the IoT device (210) until a signal is not received due to temporary interference that occurs between the AP (230) and the IoT device (210), the IoT device (210) may determine that reconnection between the AP (230) and the IoT device (210) is necessary (change of the AP (230) is necessary) if the reference signal is not received or is weakly received for a predetermined period of time or longer.

[0092] According to one embodiment, in operation 306, the IoT device (210) may generate a first packet. The first packet may include a BLE advertising packet.

[0093] According to one embodiment, the IoT device (210) may generate a first packet in response to identifying that the strength of the reference signal is less than or equal to a predetermined value.

[0094] Figure 4 illustrates an example of a first packet according to one embodiment.

[0095] According to one embodiment, the first packet (400) may include a BLE advertising packet. The BLE advertising packet may include various information about an AP (e.g., AP (230)), an IoT device (e.g., IoT device (210)), a network (e.g., network environment (200)), and / or a surrounding channel environment.

[0096] Referring to FIG. 4, according to one embodiment, the first packet (400) may include packet version information, onboarding info (410), feature information, setup info, device status information (420), and / or device identification (device ID) information (430). The setup info may include information about the manufacturer of the IoT device (MnID) and / or information about the type of the IoT device (SetupID).

[0097] According to one embodiment, the connection history information (410) may include information regarding the connection history of the AP (230) and the IoT device (210). The connection history information (410) may include information indicating whether the IoT device (210) has ever been connected to the AP (230). In other words, the connection history information (410) may include information indicating whether an owner of the IoT device (210) exists. For example, the connection history information (410) may include information indicating whether the IoT device (210) is an owned device (e.g., a device owned by an account of the control device (220).

[0098] According to one embodiment, the connection history information (410) may include information about the time when the IoT device (210) connected to the network through the AP (230), the identifier of the network (e.g., SSID), and / or the network password (PW).

[0099] In one embodiment, the device status information (420) may include information regarding the device's connection status. For example, the device status information may include a network connection request indicator (e.g., "AP connection required") indicating whether the IoT device (210) requires a network connection. The network connection request indicator may indicate that a network connection is required or that a network connection is not required.

[0100] According to one embodiment, the first packet (400) may include device identification information (430) for identifying the device. For example, the first packet (400) may include device identification information (430) that includes all or part of a serial number of the IoT device (210).

[0101] According to one embodiment, in operation 308, the IoT device (210) may transmit a first packet to the control device (220).

[0102] In one embodiment, the control device (220) may include a device paired with the IoT device (210).

[0103] In one embodiment, the IoT device (210) may transmit the first packet to the control device (220) using a short-range wireless communication technology (e.g., Bluetooth).

[0104] In one embodiment, at operation 310, the control device (220) may determine whether the IoT device (210) is an authenticated device. The operation of determining whether the IoT device (210) is an authenticated device may include the operation of determining whether the IoT device (210) is connected to the same network as the control device (220) and is a device that can be controlled by the control device (220).

[0105] According to one embodiment, although not shown in the drawing, the control device (220) may perform a connection with the AP (230). If reconnection between the IoT device (210) and the AP (230) is required due to a change in the location of the AP (230), a separate connection between the control device (220) and the AP (230) may not be required. However, if the AP (230) itself is changed (e.g., a change in the network), the connection process between the control device (220) and the AP (230) may be performed in advance.

[0106] In one embodiment, although not shown in the drawing, the control device (220) may determine whether the IoT device (210) is a previously connected device based on connection history information (410) included in a first packet (400) received from an IoT server or an AP. The connection history information (410) may include information about a device that is currently connected to a network through an AP or has previously been connected.

[0107] According to one embodiment, the control device (220) may determine whether reconnection of the IoT device (210) is required based on the first packet. If the first packet includes information indicating that the IoT device needs to reconnect to the AP (e.g., a network connection request indicator of the device status information (420)), it may be determined that reconnection of the IoT device is required.

[0108] According to one embodiment, the control device (220) may determine whether the IoT device (210) is an authenticated device based on the first packet. For example, the control device (220) may determine whether the IoT device (210) is an authenticated device based on whether the serial number of the device included in the first packet is stored in the control device (220) or an IoT server (e.g., the IoT server (240)). If the first packet includes device identification information (430) of the IoT device (210), the control device (220) may determine that the IoT device (210) is an authenticated device. If the first packet does not include device identification information of the IoT device (210), the control device (220) may determine that the IoT device (210) is an unauthenticated device.

[0109] In one embodiment, the control device (220) may generate network connection information. The control device (220) may generate network connection information for the IoT device (210) in response to identifying that the IoT device (210) is an authenticated device.

[0110] According to one embodiment, the network connection information may include a network identifier (e.g., SSID), and / or a network password (PW).

[0111] According to one embodiment, the control device (220) can generate encrypted network connection information. The second packet and / or the network connection information included in the second packet can be encrypted using a secret key.

[0112] In one embodiment, although not shown in the drawing, the IoT device (210) may receive a secret key from the network when it is first connected to the network. The IoT device (210) may be connected to the network (200) through the AP (230) before operation 304 is performed. After the IoT device (210) is connected to the network (200) through the AP (230), the IoT device (210) may receive a secret key from the network (200). In other words, the secret key may include a value exchanged at a specific point in time after the IoT device (210) and the network (200) are connected.

[0113] Figure 5 illustrates an example of network connection information according to one embodiment.

[0114] Referring to FIG. 5, according to one embodiment, the second packet (500) may include first information (510), second information (520), and third information (530). In the following description, the network connection information is described as forming part of a BLE advertising packet, and is described as having a length of 22 bytes.

[0115] Network identifier (0) Before encryption mySsidIsNewAp After encryption 2nd information 3rd information 32 byte (0x1A) 34 35 63 62 62 35 64 61 38 36 64 30 35 39 62 37 66 38 64 32 38 30 39 65 62 30 30 66 61 65 62 65 Network password (1) Before encryption myPasswordIsNewPassword After encryption 2nd information 3rd information 64 byte (0x34) 39 61 38 38 38 63 32 63 61 39 63 32 39 31 33 65 62 34 37 33 62 35 36 39 39 34 32 65 63 64 37 65 39 37 34 64 30 37 36 32 38 66 30 64 32 34 36 31 65 30 33 32 37 39 38 36 32 61 63 37 35 30 37 35

[0116] According to one embodiment, the first information (510) may include a network connection information indicator. The network connection information indicator may indicate either a network identifier or a network password. For example, referring to Table 1, when the network connection information indicator of the second packet (500) has a value of 0, the network connection information of the second packet (500) may be identified by a network identifier (e.g., mySSidIsNewAP). When the network connection information indicator of the second packet (500) has a value of 1, the network connection information of the second packet (500) may include a network password (e.g., myPasswordIsNewPassowrd). According to one embodiment, the control device (220) may encrypt the network connection information using a secret key (e.g., AES 256, CBC) to obtain an encrypted hex value.

[0117] In one embodiment, the second information (520) may include information regarding the length of the network connection information. For example, referring to Table 1, the encrypted network identifier may have a length of 32 bytes, and the second information (520) may include information regarding the length of 32 bytes.

[0118] In one embodiment, the third information (530) may include network data. The network data may include actual data values ​​(bit values). For example, referring to Table 1, the third information (530) may include actual data values ​​(e.g., at least a portion of network identifier data or network encryption data).

[0119] According to one embodiment, in operation 312, the control device (220) may generate a second packet. The second packet may include generated network connection information (e.g., first information (510), second information (520), and third information (530)).

[0120] According to one embodiment, the first information (510) may include a value indicating the order of the packets. For example, if the packet includes information about a network identifier and is the first packet, the first information (510) may have a value of 00000001. For example, if the packet includes information about a network identifier and is the second packet, the first information (510) may have a value of 00000010. For example, if the packet includes information about a network password and is the first packet, the first information (510) may have a value of 10000001. For example, if the packet includes information about a network password and is the second packet, the first information (510) may have a value of 10000010.

[0121] According to one embodiment, the control device (220) may generate at least one second packet. Each of the at least one second packet may include first information (510), second information (520), and third information (530).

[0122] According to one embodiment, the number of second packets may be determined according to network connection information. In the following description, the length of the third information (530) is 22 bytes as an example, but the length of the packet may vary. For example, referring to FIG. 5, since the maximum length of data that can be expressed in one packet is 18 bytes of the third information, two packets may be generated to transmit a network identifier (e.g., 0x41 0x50 0x01 0x1A 0x34 0x35 … 0x38) having a length of 32 bytes. Additionally, four packets may be generated to transmit a network password having a length of 64 bytes.

[0123] According to one embodiment, in operation 314, the control device (220) may sequentially transmit at least one second packet generated in operation 312 to the IoT device (210). For example, the control device (220) may transmit the at least one second packet to the IoT device (210) in a unicast, multicast, or broadcast manner.

[0124] According to one embodiment, in operation 316, the IoT device (210) may transmit a network connection request to a new AP based on the second packet received from the control device (220). In various embodiments of the present disclosure, the AP to which the IoT device (210) is previously connected may be referred to as a first AP (or old AP), and the AP to which the IoT device (210) is newly trying to connect may be referred to as a second AP (or new AP).

[0125] According to one embodiment, the IoT device (210) can decrypt at least one second packet received from the control device (220) using a secret key. The IoT device (210) can identify network connection information through decryption and, based on the decryption, transmit a network connection request to a new AP. If the IoT device (210) cannot decrypt the second packet based on the secret key, the IoT device (210) cannot transmit a network connection request to the new AP.

[0126] According to one embodiment, the control device (220) may identify that the IoT device (210) has been reconnected to the network when it receives a signal regarding network reconnection from a new AP or the IoT device (210). For example, when the control device (220) receives information from an IoT server (e.g., IoT server (240)) through an AP that the IoT device has been connected, the control device (220) may identify that the IoT device (210) has been reconnected to the network. For example, when a reconnection request indicator (e.g., AP Connection request) included in device status information of a packet received by the control device (220) from the IoT device indicates that the IoT device does not require reconnection, the control device (220) may identify that the IoT device (210) has been reconnected to the network.

[0127] Fig. 6 illustrates an operational flow of an electronic device according to one embodiment. The electronic device of Fig. 6 may include a device corresponding to an IoT device (210).

[0130] In one embodiment, the electronic device may monitor whether the strength of a reference signal (e.g., RSSI) is below a predetermined value.

[0131] In one embodiment, the electronic device may monitor whether reconnection to an AP is required. The electronic device may determine that reconnection to the AP is required if it fails to receive a signal from the first AP (e.g., if a reference signal is not received for a predetermined period of time) or if the strength of the signal received from the first AP is below a predetermined value (e.g., if the strength of the received reference signal is below a predetermined value).

[0132] In one embodiment, the electronic device can identify that the signal strength received from the first AP is below a first threshold value. If the location of the first AP or the electronic device changes to a location where they cannot exchange signals with each other, or if the first AP changes (e.g., network connection information changes), the electronic device may not be able to receive the reference signal from the first AP. Alternatively, the signal strength received by the electronic device from the first AP may decrease below a predetermined value.

[0133] According to one embodiment, the electronic device may determine that reconnection to the AP is necessary if the electronic device does not receive a reference signal from the first AP for a predetermined period of time or longer (including if the time for which the strength of the reference signal remains below a predetermined value for a predetermined period of time or longer). Since reconnection between the AP and the electronic device is not necessary until the signal is not received due to temporary interference that occurs between the AP and the electronic device, the electronic device may determine that reconnection between the AP and the electronic device is necessary (needs to change the AP) if the reference signal is not received or is weakly received for a predetermined period of time or longer.

[0134] According to one embodiment, the electronic device may generate a first packet. The first packet may include a BLE advertising packet.

[0135] According to one embodiment, the electronic device may generate the first packet in response to identifying that the strength of the reference signal is less than or equal to a predetermined value.

[0146] According to one embodiment, the second information may include information regarding the length of the network connection information.

[0147] In one embodiment, the third information may include network data. The network data may include actual data values ​​(e.g., at least a portion of network identifier data or network encryption data).

[0148] In one embodiment, the first information may include a value indicating the order of the packets. For example, if the packet contains information about a network identifier and is the first packet, the first information may have a value of 00000001. For example, if the packet contains information about a network identifier and is the second packet, the first information may have a value of 00000010. For example, if the packet contains information about a network password and is the first packet, the first information may have a value of 10000001. For example, if the packet contains information about a network password and is the second packet, the first information may have a value of 10000010.

[0149] In one embodiment, the number of second packets may be determined based on network connection information.

The electronic device can identify network connection information through the decryption and transmit a network connection request to the second AP based on the network connection information. If the electronic device cannot decrypt the second packet based on the secret key, the electronic device cannot transmit the network connection request to the second AP.

[0155] Fig. 7 illustrates an operational flow of a control device according to one embodiment. The control device of Fig. 7 may include the control device (220) of Fig. 2. In addition, the IoT device of Fig. 7 may include the IoT device (210) of Fig. 2 and the electronic device of Fig. 6.

[0158] In one embodiment, the control device can determine whether the IoT device is an authenticated device. Determining whether the device is an authenticated device may include determining whether the device is connected to the same network as the control device and can be controlled by the control device.

[0159] In one embodiment, although not shown in the drawing, the control device may establish a connection with the AP. If a reconnection between the IoT device and the AP is required due to a change in the location of the AP, a separate connection between the control device and the AP may not be required. However, if the AP itself changes (e.g., due to a network change), the connection process between the control device and the AP may be performed first.

[0160] In one embodiment, although not shown in the drawing, the control device may determine whether the IoT device is a device that has previously been connected based on connection history information (e.g., connection history information (410) of FIG. 4) included in a first packet (e.g., first packet (400) of FIG. 4) received from an IoT server or an AP. The connection history information may include information about a device that is currently connected or has been connected to the network via the first AP.

[0161] In one embodiment, the control device may determine whether reconnection of the IoT device is required based on the first packet. If the first packet includes information indicating that the IoT device needs to reconnect to the AP (e.g., a network connection request indicator in the device status information), the control device may determine that reconnection of the IoT device is required.

[0162] In one embodiment, the control device may determine whether the IoT device is an authenticated device based on the first packet. For example, the control device may determine whether the IoT device is an authenticated device based on whether the serial number of the device included in the first packet is stored in the control device (220) or an IoT server (e.g., IoT server (240)). If the first packet includes device identification information of the IoT device, the control device may determine that the IoT device is an authenticated device. If the first packet does not include device identification information of the IoT device, the control device may determine that the IoT device is an unauthenticated device.

[0163] In one embodiment, the control device may generate network connection information. The control device may generate network connection information for the IoT device in response to identifying the IoT device as an authenticated device.

[0167] According to one embodiment, the second packet may include first information (e.g., first information (510)), second information (e.g., second information (520)), and / or third information (e.g., third information (530)).

[0168] In one embodiment, the first information may include a network connection information indicator. The network connection information indicator may indicate either a network identifier or a network password. For example, referring to Table 1, if the network connection information indicator of the second packet has a value of 0, the network connection information of the second packet may be identified by a network identifier (e.g., mySSidIsNewAP). If the network connection information indicator of the second packet has a value of 1, the network connection information of the second packet may include a network password (e.g., myPasswordIsNewPassowrd).

[0169] According to one embodiment, the control device can obtain an encrypted hex value by encrypting network connection information using a secret key (e.g., AES 256, CBC).

[0170] In one embodiment, the second information may include information regarding the length of the network connection information. For example, the encrypted network identifier may be 32 bytes long, and the second information may include information regarding the 32-byte length.

[0171] In one embodiment, the third information may include network data. The network data may include actual data values. For example, the third information may include actual data values ​​(e.g., at least a portion of network identifier data or network password data).

[0172] In one embodiment, the control device may generate a second packet. The second packet may include generated network connection information (e.g., first information, second information, third information).

[0173] In one embodiment, the first information may include a value indicating the order of the packets. For example, if the packet contains information about a network identifier and is the first packet, the first information may have a value of 00000001. For example, if the packet contains information about a network identifier and is the second packet, the first information may have a value of 00000010. For example, if the packet contains information about a network password and is the first packet, the first information may have a value of 10000001. For example, if the packet contains information about a network password and is the second packet, the first information may have a value of 10000010.

[0174] According to one embodiment, the control device may generate at least one second packet. Each of the at least one packet may include first information, second information, and / or third information.
