[0043] The embodiments in the present application and the features in the embodiments can be combined with each other under the condition of no conflict.

[0044] Future development of the Internet of Things (IoT) can result in the deployment of networks of millions or even billions of small, low-power IoT devices to meet the needs of various applications. However, it is unrealistic for all IoT devices to rely on batteries that need to be manually replaced or charged, which is not only costly but can also cause environmental and safety problems. What is needed in practical applications are small, simple battery-free devices or devices with limited energy storage and no need for manual charging, which typically output power between 1 microwatt and a few hundred microwatts.

[0045] Wireless radio frequency identification devices, i.e. RFID (Radio Frequency Identification) devices, although low power consumption, have limited communication distance and capacity, resulting in high cost of deploying IoT and not suitable for the development of future IoT. In addition, due to the lack of interference management solutions, serious interference and capacity problems between RFID readers are particularly prominent, especially in the case of dense deployment. It is difficult for RFID to support large-scale IoT networks with seamless coverage. Therefore, ambient power-enabled IoT (ambient power-enabled IoT), abbreviated as AIoT (Ambient IoT), has emerged.

[0046] In the 5G Release 19 work plan published by 3GPP, the following two types of AIoT network deployments will be supported (in actual deployment, there can be a mixed deployment of the two types). Figure 1a provides a schematic diagram of one type of network deployment, in which AIoT devices can directly send their AIoT information / data (i.e. send AIoT messages) to a base station and directly receive AIoT information / data (i.e. receive AIoT messages) from the base station. Here, a base station can be defined as a radio access network AIoT reader (RAN AIoT reader).

[0047] Figure 1b provides a schematic diagram of another network deployment, as shown in Figure 1b. In the AIoT system, considering that the coverage area of the base station and the AIoT device in the 5G AIoT network is limited (for example, the transmission and / or reception range is limited), one or more intermediate nodes between the base station and the AIoT device can be used to expand the coverage area. Generally, a user equipment UE (User equipment) or a relay node can be used as an intermediate node. The AIoT device can send its AIoT information / data (i.e., send AIoT messages) to the base station through a certain AIoT-capable UE, and receive AIoT information / data (i.e., receive AIoT messages) from the base station through a certain AIoT-capable UE. Here, the base station and one or more UEs within the coverage area of the base station can be defined together as a wireless access network AIoT reader.

[0048] The wireless access network AIoT reader can receive operation instructions for AIoT from the 5G core network, and the operation instructions can include at least one of an inventory or a command, the meanings of which in this document are as follows:

[0049] Inventory: a process for discovering and obtaining the identifier of a single or a group of AIoT devices, and can also require the AIoT device to report additional data (such as device production date, device type, and device location) at the same time; Command: a process for sending an operation request (for example, read, write) to the AIoT device.

[0050] In some embodiments, the first communication node can be a wireless access network AIoT reader, for example, a base station; the second communication node can be an AIoT device. The third communication node can be a core network (CN, Core Network).

[0053] The first request information can be understood as an indication information indicating the second communication node to execute a corresponding command, for example, to execute an inventory operation, to execute a command operation, etc. The device identifier can be understood as an information uniquely identifying the device, which can be a number, a letter, a special character, etc., or can be composed of one or more characters such as a number, a letter, and a special character. In this application, the device identifier generally refers to device identification information, which can be used to identify the device. The invisible data refers to data processed by encryption or the like, so that the content cannot be directly obtained. Any private data that needs to be kept secret can be processed as invisible data for transmission.

[0054] The first communication node sends the first request information to one or more second communication nodes. The first communication node can send the first request information to one or more second communication nodes within the coverage range of the first communication node.

The first request information includes at least one device identifier and corresponding invisible data for each device identifier. The device identifier is visible data. The first request information is used to instruct the second communication node to execute a corresponding command. The device identifier in the first request information can be used to indicate whether the second communication node needs to execute the corresponding command. The invisible data can be information required during the execution of the command, or any data that needs to be transmitted.

The first communication node receives one or more first feedback information fed back by the second communication node for the first request information.

[0064] The first feedback information includes at least one of the device identifier and the invisible data of the second communication node, that is, the second communication node carries one of the device identifier and the invisible data of the device in the first feedback information when generating the first feedback information; the invisible data is data invisible to the first communication node, that is, invisible to the first communication node, to avoid data leakage; the device identifier is visible data.

[0067] The second request information can be understood as an indication information for requesting the first communication node to execute a corresponding command for the corresponding second communication node, for example, to execute an inventory operation, to execute a command operation, etc.

[0068] The first communication node receives the second request information sent by the third communication node before sending the first request information to the second communication node, and executes a corresponding command for the corresponding second communication node according to the indication of the second request information. The second request information includes: device identifiers of at least one second communication node and corresponding invisible data of each device identifier, the invisible data being data invisible to the first communication node, and the invisible data including command information of the device. After receiving the second request information, the first communication node determines the second communication node that needs to execute the corresponding command according to the device identifier carried in the second request information.

[0078] In some embodiments, before the first communication node sends the first request information to the second communication node, the first communication node can also send an inventory message to the second communication node to inventory the second communication node. The first communication node saves the device identifier of the second communication node after receiving the feedback information of the second communication node, at this time, it can be considered that the first communication node discovers this second communication node, or the first communication node establishes an association relationship with this second communication node. The first communication node can send the first request information to the second communication node after establishing the association relationship with the second communication node, and request the second communication node to execute the corresponding command.
