As more IoT devices are introduced to the market, consumers are provided with various options to utilize the IoT devices. The tendency of consumers to use different IoT products that fit their needs (price, features, etc.) will cause the consumers to purchase IoT products from different vendors. On the other hand, the fragmentation in the IoT industry such as "No Global Standard" will lead the IoT vendors to build their own proprietary IoT services (cloud) and the IoT standard for their own IoT devices. This implication will make the consumer to register multiple accounts of the IoT services for the different IoT vendors and make consumers pair and manage their heterogeneous IoT devices and the IoT services by themselves.
To address arising issues in the heterogeneous IoT devices and IoT services, the apparatus and methods may simplify the pairing process of the IoT device and service. The disclosure will implement user authentication for the C2C pairing, the tag based on the pairing for D2C, the apparatus and the method to obtain device information from the scanned TAG, and the apparatus and the method to execute the pairing process of C2C or D2C.
The disclosure will bring advantages for the users such as: 1) easy pairing; The disclosure may allow pairing the IoT device with the IoT service automatically and simply using a tag-based identifier (an image tag or a radio tag) to identify the IoT devices, regardless of their vendor or standard; 2) single application pairing; Instead of installing IoT applications for every IoT vendors, the disclosure may allow users to pair their IoT devices from different vendors and connect the IoT devices to the external IoT services using the C2C mechanism only from a single IoT application; and 3) flexible pairing; user may enjoy the flexibility of choosing compatible IoT service to which he/she wants to connect his/her IoT device without difficulty.
Embodiments of the disclosure herein may have two main features. First, the embodiment herein will enable a seamless pairing process of the IoT devices and the IoT services in the heterogeneous IoT ecosystem by building an automatic pairing module (APM) which automates the pairing process seamlessly using the IoT information, the user preference, and/or the custom pairing procedure and utilizing the IoT information service which provides the IoT device information and the IoT service information for enabling the automatic pairing process.

The tag itself may include information to retrieve the IoT device information in the IoT information service entity. To be able to execute or perform pairing process between the IoT device and the IoT service, the client device may have an IoT application to send the tag information to the IoT service, a tag reader in the client device or the external tag reader device, and the network connection. For example, the tag may include a visual tag (ex. QR Code), a radio tag (ex. NFC TAG), and/or a tag via a wearable device, a camera, a radio reader, etc, but the tag is not limited thereto.
FIG. 12 illustrates how the IoT system to support the D2C pairing process according to an embodiment of the disclosure.
Referring to FIG. 12, it is illustrated how the IoT system may support the D2C pairing process, which has capability to: read the tag, obtain the IoT device information according to the tag information, create and execute the automation pairing procedure, and pair the IoT device with the external IoT service.
FIG. 13 is a flowchart illustrating the detailed process and the system to support the device to cloud (D2C) IoT pairing mechanism according to an embodiment of the disclosure.
Referring to FIG. 13, a user may scan the tag in the IoT device. The IoT device itself must be in the pairing state (state when the IoT device is able to be paired with the IoT service). There are 2 scenarios of scanning the tag based on the tag reader: (1) internal tag reader: The tag reader will scan the tag in the IoT device to obtain the tag information; and (2) external tag reader: The external tag reader will scan the tag in the IoT device to obtain the tag information, and send the tag information to the IoT application. The tag information and the request for the D2C pairing may be sent by the IoT application to the primary IoT service A. The primary IoT service A will process the pairing request and the tag information in the automatic pairing module (APM) to start the D2C pairing process. Information from the tag information will be used to obtain the device information in the IoT information service.
Referring to FIGS. 12 and 13, the automatic pairing module (APM) may request the IoT device information based on the tag information to the IoT information service. The APM may also request additional information like a custom pairing procedure, and the IoT service information from the storage module or the IoT information service. After receiving the IoT device information and/or the additional information, the APM will generate a pairing procedure and execute the pairing procedure to execute or call modules inside the primary IoT service. The automatic pairing module (APM) may request the C2C module or the D2C module to start the pairing process according to the execution of the pairing procedure. Based on the pairing procedure, there may be several pairing scenarios between the IoT device and the IoT services, such as: If the IoT device is paired with the external IoT service B, then the APM will first request or ask the C2C module to start the C2C pairing with the external IoT service B (if not paired yet). If the primary IoT service A is paired with the external IoT service B, then the APM will instruct the C2C module to start the pairing process between the external IoT service and the IoT device; If the IoT device is paired directly with the primary IoT service A, then the APM will instruct the D2C module to start the pairing procedure to the IoT device; If the IoT device is paired indirectly (via Hub) with the primary IoT service A, then the APM may instruct the D2C module to execute or call the paired IoT hub to execute or perform the pairing process with the IoT device. If the IoT device is already paired with the IoT service, then the user can monitor, control and manage the IoT device via the IoT application.
FIGS. 14A and 14B illustrate of the D2C pairing by scanning the tag which shows a flow of the user interface during the D2C pairing process according to various embodiments of the disclosure.
Referring to FIGS. 14A and 14B, in operation 1410, the user may select at least one option to add at least one new device to process the D2C pairing. In operations 1420 and 1430, the user needs to scan the tag attached to the IoT device. For example, in operation 1420, the user may scan the visual tag (ex. QR Code) attached to the IoT device. For another example, in operation 1430, the user may scan the radio tag (ex. NFC Tag) attached to the IoT device. In operation 1440, the user may select the IoT service which one the user wants to connect to the IoT devices. If the user selects the unpaired external IoT service, in operation 1450, the system may establish the C2C pairing between the external IoT services and the internal IoT service. In addition, the system will start the D2C pairing between the external IoT service and the IoT device via the C2C module after the C2C pairing process is finished. However, if the user selects the primary IoT service or the paired external IoT service, in operation 1460, the system may detect that the IoT device need to be connected to the IoT hub, then the user may select the IoT hub to which the user wants connect with the IoT device. In operation 1470, the user may go back to the main page of the IoT application.
