This application claims priority to and the benefit of Korean Patent Application Nos. 10-2021-0075888 and 10-2022-0042386 filed in the Korean Intellectual Property Office on Jun. 11, 2021, and Apr. 5, 2022, the entire contents of which are incorporated herein by reference.
The present invention relates to a method and apparatus for device provisioning, and more particularly, to a method and apparatus for device provisioning to provision an IoT (Internet of things) device so that the IoT device can connect to an existing IoT network.
Currently, IoT (Internet of things) devices are receiving services by connecting an IoT repeater [e.g., WiFi AP (Access Point), PAN (Personal Area Network) coordinator, Bluetooth pairing, gateway, etc.] according to a communication method [e.g., WiFi, Zigbee, BLE (Bluetooth Low Energy), IEEE 802.15.4, LPWA (Low Power Wide Area), etc.] supported by each device.
These IoT devices or IoT repeaters provide various types of connection methods for each selling company or communication method. In some cases, the smart terminal connects to the IoT device and changes the network setting of the IoT device so that the IoT device can connect to the IoT repeater. However, in the absence of the IoT repeater, there are many IoT devices in which it is difficult to set up a network through a smart terminal.
When a new IoT device is added to the currently operating general IoT network currently in operation or secure IoT network, connection initialization information must be provided in various forms depending on the communication method to the new IoT device. However, each company does not disclose connection initialization information, and most of the connection initialization information for each company is configured in a form that is difficult for third-party IoT devices to connect.
In addition, if a new IoT device can connect through one-to-one communication such as Bluetooth or WiFi, network setting is possible, but it is generally difficult to add various communication devices to an IoT device.
As such, the communication method or initial connection method is different depending on the manufacturer of the IoT device, so it is difficult to connect the IoT device and the IoT repeater. Even when the device is connected through standardized communication methods such as WiFi, Zigbee, BLE, IEEE 802.15.4, LPWA, etc., the network connection information of the currently operating IoT repeater is not set in the new IoT device, so a situation in which it is difficult for the device to initially access the operating IoT network or secure IoT network occurs.
The disclosure has been made in an effort to provide a method and apparatus for device provisioning capable of adding a new IoT device to an operating IoT network without affecting the operating IoT network.
According to an exemplary embodiment, a method for provisioning so that a new device can connect a first repeater in the smart terminal is provided. The method for device provisioning includes: changing the network setting information of a second repeater constituting a network for installation based on the initial setting information of the new device; and when the new device connects to the second repeater using the initial setting information of the new device, changing the network setting information of the new device to the network setting information of the first repeater.
The changing of the network setting information of the new device may include connecting to the second repeater; and searching the new device from among devices connected to the second repeater by using the initial setting information of the new device.
The method for device provisioning may further include obtaining the initial setting information of the new device, wherein the initial setting information may include network setting information for network connection of the new device.
The obtaining may include obtaining the initial setting information through at least one of a QR (Quick Response) code of the new device, barcode recognition, or information provided by the cloud.
The changing of the network setting information of the second repeater may include changing the network setting information of the second repeater to the network setting information of the new device.
The method for device provisioning may further include connecting, by the new device, to the first repeater using the changed network setting information.
According to another embodiment, an apparatus for device provisioning so that a new device can connect a first repeater is provided. The apparatus for device provisioning includes a communicator and a connection setter. The communicator supports a plurality of network communication methods and communicates through a network connection with a second repeater constituting a network for installation. The connection setter induces the new device to connect to the second repeater based on the initial setting information of the new device, searches the new device among devices connected to the second repeater, and changes the network setting information of the searched new device to the network setting information of the first repeater.
The apparatus for device provisioning may include a device information checker that obtains the initial setting information of the new device, and the initial setting information may include network setting information for network connection of the new device.
The device information checker may obtain the initial setting information through at least one of a QR (Quick Response) code of the new device, barcode recognition, or information provided by the cloud the device information.
The connection setter may change the network setting information of the second repeater to the network setting information of the new device.
Hereinafter, embodiments of the disclosure will be described in detail with reference to the attached drawings so that a person of ordinary skill in the art may easily implement the disclosure. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Like reference numerals designate like elements throughout the specification.
Throughout the specification and claims, when a part is referred to “include” a certain element, it means that it may further include other elements rather than exclude other elements, unless specifically indicated otherwise.
Now, a method and apparatus for device provisioning according to an embodiment will be described in detail with reference to the drawings.

An IoT device 110 participates in the IoT network by connecting to the operational IoT repeater 120. The IoT network may include both a general IoT network without security support or a secure IoT network with enhanced security.
The operational IoT repeater 120 collects data of the connected IoT device 110 and transmits the collected data to the cloud through interworking with an external Internet.
The IoT device 130 is a device intended to connect the IoT network in operation for the first time, and will be referred to as a new device 340 in order to distinguish it from the IoT device 110 already participating in the IoT network.
The new device 130 has initial setting information set at the time of manufacture. The initial setting information may include manufacturer initial information, network setting information for network connection, and the like.
In order for the new device 130 to connect the IoT network, it must know the network connection information of the IoT network. If the new device 130 cannot access the IoT network using the network setting information set in the new device 130, as the new device 130 needs to change the network setting information so that it can access the IoT network.
For example, when using a WiFi network, the operating IoT repeater 120 supports the AP function, and the new device 130 requires network connection information such as an SSID (Service Set Identifier), secure-type, and password, which are information necessary for WiFi access to the AP. However, since the new device 130 does not know the network connection information for accessing the IoT network, it cannot access the IoT network.
In addition, when the new device 130 and the smart terminal 150 are directly connected through a communication method such as Bluetooth pairing, the network setting information of the new device 130 can be changed to the network connection information of the IoT network through the smart terminal 150. However, in the case of the new device 130 that cannot support direct connection with the smart terminal 150, a method for setting the network connection information of the IoT network to the new device 130 is required.
According to an embodiment, an installed IoT repeater 140 is used for initial connection to the IoT network of the new device 130.
Since the installed IoT repeater 140 supports various communication methods, it is possible to provide a communication method suitable for the new device 130.
The smart terminal 150 checks the initial setting information of the new device 130, connects to the installed IoT repeater 140, and changes network setting information of the installed IoT repeater 140 using the network setting information of the new device 130, so that the new device 130 can connect to the installed IoT repeater 140. Next, when the new device 130 connects to the installed IoT repeater 140, the smart terminal 150 changes the network setting information of the new device 130 so that the new device 130 can connect the IoT network.
Referring to
First, the smart terminal 150 obtains the initial setting information provided by the new device 130 (S210). The smart terminal 150 can check initial setting information provided by the new device 130 through QR (Quick Response) code using a camera, barcode recognition, a serial number provided by the manufacturer of the new device 130, or information provided by the cloud. The new device 130 tries to connect the network according to the network setting information among the initial setting information.
After checking the initial setting information of the new device 130, the smart terminal 150 connects to the installed IoT repeater 140. The smart terminal 150 may connect to the installed IoT repeater 140 by using a communication method suitable for the smart terminal 150 among the network communication methods provided by the installed IoT repeater 140. For example, assuming that the installed IoT repeater 140 supports various network communication methods including WiFi or Bluetooth communication methods, the smart terminal 150 may connect to the installed IoT repeater 140 using the internally set WiFi or Bluetooth communication method.
Next, the smart terminal 150 changes the network setting information of the installed IoT repeater 140 based on the network setting information of the new device 130 so that the new device 130 can connect to the installed IoT repeater 140 (S220). For example, if the network setting information of the installed IoT repeater 140 is set to the A network environment, and the network setting information of the new device 130 is set to the B network environment, the smart terminal 150 changes the network setting information of the installed IoT repeater 140 to the B network environment so that the new device 130 can connect to the installed IoT repeater 140.
After changing the network setting information of the installed IoT repeater 140, the new device 130 can connect to the installed IoT repeater 140 (S230).
Next, the smart terminal 150 connects to the installed IoT repeater 140 in which the network setting information is changed (S240), and searches the new device 130 among the devices connected to the installed IoT repeater 140 based on the initial setting information of the new device 130 obtained through the step (S210).
Next, the smart terminal 150 changes the network setting information of the new device 130 searched based on the already known network connection information of the IoT network to the C network environment (S250).
Then, the new device 130 connects to the operational IoT repeater 120 based on the changed network setting information (S260). In addition, the new device 130 stores network connection information of the IoT network in firmware.

In the QR code or barcode recorded when the new device 130 is manufactured, the communication physical address (MAC address in the case of WiFi, MAC address in the case of Zigbee) of the new device 130 and information of the repeater (WiFi AP, gateway, coordinator, etc.) for access of the new device 130 and the like as the basic network setting information for network connection of the manufactured new device 130 are included. However, since it is difficult to connect to the existing IoT network or secure IoT network using the initially recorded information, the initial connection is resolved through the following process.
For the initial connection of the new device 130, the smart terminal 150 may connect to the installed IoT repeater 140 using an accessible communication method provided by the installed IoT repeater 140.
The installation application included in the smart terminal 150 connects to the installed IoT repeater 140 of the network environment A, and then changes the network setting of the installed IoT repeater 140 to the B network environment using the initial setting information obtained from the new device 130 and restarts the installed IoT repeater 140, so that the new device 130 can connect to the installed IoT repeater 140.
The smart terminal 150 connects to the installed IoT repeater 140 in the B network environment, checks the physical address of the new device 130 obtained from a QR code or barcode among device information connected to the installed IoT repeater 140, selects the new device 130, and sets the network connection information of the C network environment for the IoT network in operation to the selected new device 130 by using prior knowledge of the IoT network in operation. In the case of WiFi environment setting, the network connection information includes the WiFi SSID, security type, password, etc. of the operating IoT repeater 120, and in the case of the IEEE 802.15.4 series Zigbee environment setting, the network connection information includes PAN-ID, access channel, code, and the like.
The new device 130 records network connection information of the C network environment in the firmware.
When the new device 130 for which the network setting is completed is restarted, the new device 130 connects to the IoT network of the C network environment in operation according to the network setting information of the C network environment set in the firmware of the new device 130, and then various cloud applications can be interworked through the application service.
