Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to an environmental Internet of Things (IoT) communication method, system, environmental IoT access network device, environmental IoT core network device, terminal reader / writer, environmental IoT device, electronic device, medium, and program product. Background Technology

[0002] Currently, barcodes and Radio Frequency Identification (RFID) technologies are widely used in many industries. RFID technology is a non-contact automatic identification technology that uses wireless radio frequency signals for two-way data communication to identify target objects and exchange data. An RFID system typically consists of RFID tags, readers, and a backend database system. When an object with an RFID tag approaches the reader, the reader emits a specific frequency radio frequency signal. The tag obtains energy through electromagnetic induction or microwave energy harvesting to activate its own circuitry, and then feeds back the information stored in its chip to the reader in the form of a radio frequency signal. The reader then decodes this information and transmits it to the backend system for processing. Barcode technology is already very mature and is widely used in almost all retail and logistics industries. Both technologies offer the advantages of extremely low tag complexity and small size.

[0003] Because barcode and RFID tags have limited reading range (typically only effective within a few meters), they often require scanning with handheld devices, leading to additional labor costs and time-consuming operations. In some scenarios, RFID access control systems may be installed to address these issues, but this introduces cost problems, as deploying RFID access control systems is often accompanied by high deployment costs. Furthermore, due to the lack of suitable interference management solutions, especially in dense deployment scenarios, RFID readers often experience severe interference and capacity issues.

[0004] Based on this, environmental IoT technology has emerged. Application scenarios for environmental IoT include various asset identification and management, covering fields such as logistics, warehousing, smart cities, precision agriculture, medical systems, and consumer electronics. Among these, environmental IoT devices are IoT devices that do not require built-in batteries or external power sources, achieving data acquisition and communication by collecting environmental energy (such as radio frequency signals, light energy, and heat energy).

[0005] In contrast, environmental IoT solutions in 3GPP scenarios, based on high-performance cellular base stations and continuous tag networking, have significant advantages in coverage, inventory accuracy, and passive positioning capabilities. Relevant standard documents define representative use cases, deployment scenarios, connection topologies, environmental IoT devices, design goals, and required functionalities.

[0006] However, the environmental IoT communication methods disclosed in related technologies are usually mainly aimed at non-3GPP systems or focus on the configuration methods related to the physical layer of A-IoT wireless air interface, without clearly describing the overall communication process. That is, the related technologies have not designed the necessary communication and signaling processes between environmental IoT devices, access network devices and core network devices, resulting in poor operability in specific implementation.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

Specifically, the collected data can be transmitted to the environmental IoT access network node via the A-IoT radio interface, and control commands can be received from the terminal reader or core network node. The A-IoT radio interface is a wireless communication interface used between the environmental IoT access network node and the environmental IoT device to ensure low-power, long-distance wireless communication, thereby supporting data transmission by the environmental IoT device.

[0115] In one embodiment of this disclosure, if no manual intervention is required or the environmental IoT device can be directly deployed, the environmental IoT communication method can be realized only by the environmental IoT core network node, the environmental IoT access network node, and the environmental IoT device; if manual intervention is required or the environmental IoT device cannot be directly deployed, the communication between the environmental IoT device and the environmental IoT access network node needs to be realized indirectly through a terminal reader / writer, thereby realizing the environmental IoT communication method.

[0116] In one embodiment of this disclosure, the terminal reader / writer serves as the entry point for interaction between the user or device and the A-IoT network. It is used for data collection, uploading, and issuing control commands. Specifically, it communicates with environmental IoT devices via an A-IoT radio interface and with environmental IoT access network nodes via a Uu interface, enabling remote monitoring and management of these devices. The Uu interface is typically a wireless interface between the user equipment and the base station. In this embodiment, the Uu interface is a wireless communication interface used between the terminal reader / writer and the environmental IoT access network nodes, allowing the terminal reader / writer to send query requests or control commands and receive data feedback from the environmental IoT devices.

[0117] In one embodiment of this disclosure, if the environmental IoT device can communicate directly with the environmental IoT access network node, the environmental IoT device collects environmental data (such as temperature, humidity, etc.) through sensors and sends the data to the environmental IoT access network node through an A-IoT radio interface. After receiving the data, the environmental IoT access network node forwards the data to the environmental IoT core network node through an interface. The environmental IoT core network node processes and analyzes the received data, thereby generating corresponding control commands or decision results. The environmental IoT core network node sends the control commands back to the environmental IoT access network node through an interface. The environmental IoT access network node then sends the commands to the corresponding environmental IoT device through the A-IoT radio interface. The environmental IoT device performs corresponding operations according to the received control commands and sends new status or data to the environmental IoT access network node as needed through the A-IoT radio interface.

[0118] In one embodiment of this disclosure, if the environmental IoT device cannot communicate directly with the environmental IoT access network node, the environmental IoT device sends data to the terminal reader / writer through the A-IoT radio interface; the terminal reader / writer can interact with the environmental IoT access network node through the Uu interface to obtain real-time data or issue control commands.

Any number of environmental IoT access network nodes, environmental IoT devices, and terminal readers can be used as needed. This disclosure does not limit the number of such elements.

After pre-determining the estimated number of devices to be inventoried, the A-IoT RAN node can monitor and determine the end time of the ongoing A-IoT device inventory process.
