[0174] In the related art, Ambient IOT is an advanced IOT technology. Ambient IOT devices in Ambient IOT do not need to be built-in batteries or external power supplies, and can be activated and data transmission only by relying on external energy supply, thereby avoiding the maintenance cost and trouble caused by periodic battery replacement, reducing the use cost, and reducing energy consumption and adverse effects on the environment caused by battery use. In addition, Ambient IOT devices are small in size and easy to integrate into various objects, and can be more conveniently deployed in various environments.

[0175] 6G IOT technology is an IOT technology that is expected to achieve higher data transmission speed, lower latency, greater connection density, and more reliable communication, so that data transmission and communication between IOT devices can be faster and more stable, further pushing the network speed, capacity and connectivity of IOT technology, and providing better support for more smart devices and IOT applications.

[0176] Therefore, Ambient IOT technology and 6G IOT technology have become two important research directions for future IOT technology.

[0177] In some embodiments, Ambient IOT devices and IOT devices can access the network in various ways. Taking Ambient IOT devices as an example, Ambient IOT devices can achieve network access in the following two ways.

[0178] Referring to FIG. 2A, FIG. 2A is a network topology diagram according to an embodiment of the present disclosure, taking an access network device as a base station as an example, as shown in FIG. 2A, Ambient IOT devices and base stations can directly transmit and receive data (including uplink data and downlink data).

[0179] Referring to FIG. 2B, FIG. 2B is another network topology diagram according to an embodiment of the present disclosure, taking an access network device as a base station as an example, as shown in FIG. 2B, Ambient IOT devices and base stations can indirectly transmit and receive data (including uplink data and downlink data), and intermediate nodes can play a data forwarding function between Ambient IOT devices and base stations.

[0180] It should be noted that the above are only two exemplary access methods and do not constitute a limitation on the access method of Ambient IOT devices.

[0181] In some embodiments, Ambient IOT devices can be divided into type 1 (type 1) and type 2 (type 2).

[0182] Among them, the Ambient IOT device of type1 type has energy storage, but does not have independent signal generation and signal amplification, and needs to rely on backscatter to realize uplink transmission. The Ambient IOT device of type2 type has energy storage, and has independent signal amplification, and the uplink transmission can be generated internally or rely on backscatter to realize.

[0183] In some embodiments, the Ambient IOT device of type2 type can be further divided into type2a (type2a) and type2b (type2b).

[0184] Among them, the Ambient IOT device of type2a type has energy storage, and has independent signal amplification, and the uplink transmission relies on backscatter. The Ambient IOT device of type2b type has energy storage, and has independent signal amplification, and the uplink transmission can be realized based on the internally generated signal.

[0185] It should be noted that the Ambient IOT device needs a core network device (such as a core network function node) to support the processing of Ambient IOT services, and the IOT device (such as a 6G IOT device) needs a core network device (such as a core network function node) to support the processing of IOT services, that is, whether it is an Ambient IOT device or an IOT device, it needs a core network device to support the processing of services. However, different core network devices may support different services, so when selecting a core network device to provide services for the Ambient IOT device or the IOT device, it is necessary to ensure that the services supported by the selected core network device meet the service requirements of the Ambient IOT device or the IOT device, so as to avoid the initial blind selection of a core network device that does not support the corresponding service, resulting in subsequent services cannot be initiated, or the initial blind selection of a core network device that does not support the corresponding service, resulting in the need to perform core network device reselection, thereby introducing additional latency.
