- the electronic tag can use the energy obtained from the electromagnetic field generated in the space to transmit the information stored in the electronic tag.
- the reader can read the information and decode it to identify the electronic tag.
- Zero-power technology mainly combines RF energy collection technology, backscattering technology, and low-power computing technology to achieve the advantage of device nodes not carrying power supplies.
- the core of RF energy collection is to convert RF energy into DC.
- the energy can be stored in batteries or capacitors, or it can be directly used to drive logic circuits, digital chips or sensor devices after collection, to complete the modulation and transmission of backscattered signals, the collection and processing of sensor information and other functions and applications.

- terminals can be divided into three categories based on their energy sources and energy usage: passive zero-power terminals, semi-passive zero-power terminals, and active zero-power terminals. They are introduced below.
- Passive zero-power terminals do not need internal batteries.
- a zero-power terminal When a zero-power terminal is close to a reader (such as a reader of a radio frequency identification (RFID) system), the zero-power terminal is within the near field formed by the radiation of the reader antenna.
- the passive zero-power terminal antenna generates an induced current through electromagnetic induction, which drives the low-power chip circuit of the zero-power terminal, thereby realizing the demodulation of the forward link signal and the modulation of the backward link signal.
- the passive zero-power terminal uses the backscatter implementation method to transmit the signal.
- the passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link, and is a truly zero-power terminal.
- Passive zero-power terminals do not require batteries, and the RF circuit and baseband circuit are very simple. For example, they do not require low-noise amplifiers (LNA), power amplifiers (PA), crystal oscillators, analog-to-digital converters (ADC), etc. Therefore, passive zero-power terminals have many advantages such as small size, light weight, low price, and long service life.
- LNA low-noise amplifiers
- PA power amplifiers
- ADC analog-to-digital converters
- passive zero-power terminals may also include: 1) no battery; 2) the ability to obtain energy from the surrounding environment (such as radio waves, solar energy, wind energy, mechanical kinetic energy, etc.); 3) no universal subscriber identity module (USIM) card.
- This type of terminal device can also store a certain amount of energy through the surrounding environment, but the energy is very small. Therefore, compared with ordinary mobile phone terminals, passive zero-power terminals support much less functional logic.
- the semi-passive zero-power terminal itself does not have a conventional battery installed, but can use a radio frequency (RF) energy harvesting module to harvest radio wave energy and store the harvested energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can drive the low-power chip circuit of the zero-power terminal to achieve forward link signal demodulation and backward link signal modulation. For the backscatter link, the semi-passive zero-power terminal uses the backscatter implementation method to transmit the signal.
- RF radio frequency
- the semi-passive zero-power terminal does not need a built-in battery to drive the forward link or the reverse link.
- the energy stored in the energy storage unit is used in the work, the energy comes from the radio energy collected by the energy collection module. Therefore, this type of terminal equipment is also a true zero-power terminal.
- Semi-passive zero-power consumption terminals inherit many advantages of passive zero-power consumption terminals, namely, small size, light weight, very cheap price, long service life and many other advantages.
- the zero-power terminal can also be an active zero-power terminal, which can have a built-in battery.
- the battery is used to drive the low-power chip circuit of the zero-power terminal, thereby realizing the demodulation of the forward link signal and the signal modulation of the reverse link.
- the zero-power terminal uses the backscatter implementation method to transmit the signal. Therefore, the zero power consumption of this type of terminal is mainly reflected in the fact that the signal transmission of the reverse link does not require the terminal's own power, but uses the backscatter method.
- Active zero-power terminals can have built-in batteries to power RFID chips, thereby increasing the read and write distance of tags and improving communication reliability. Therefore, such terminal devices can be used in some scenarios with relatively high requirements for communication distance, reading delay, etc.
- the above-mentioned zero-power terminal device may include: an ambient power-enabled internet of things (AIoT) device.

For example, before the first terminal device sends the first information, the first terminal device can send the first request. When the first terminal device receives a response to the first request, the first terminal device can send the first information.
- the present application does not limit the message that carries the first request.
- the first request can be carried in an uplink (UL) non-access stratum (NAS) transmission message.
- the first request can be carried in the request type (request type) in the uplink NAS transmission message. That is, the request type can indicate that the first request is used to discover the first core network element.

- the first indication information may be information related to the selection or determination of the first core network element. That is, according to the first indication information, the network device may select or determine a suitable first core network element, thereby optimizing the communication process. For example, when the network When there are multiple optional core network elements for collecting AIoT device information in the network, the network side can further select a core network element for collecting AIoT device information that meets the requirements of the first indication information as the first core network element.
- the first indication information may, for example, include one or more of the following information: an indication of a core network element requesting discovery of terminal device information, an identifier of the AF, an identifier of a service provider, and an identifier of an application.
- the indication of requesting to discover the core network element for collecting terminal device information can be represented by one bit.
- the one bit can be 0 or 1.
- the terminal device requests to discover the first core network element through the indication; when the indication of requesting to discover the core network element for collecting terminal device information is 0, the terminal device does not request to discover the first core network element through the indication.
- the terminal device requests to discover the first core network element through the indication; when the indication of requesting to discover the core network element for collecting terminal device information is 1, the terminal device does not request to discover the first core network element through the indication.

- the first core network element may be different from any core network element shown in FIG1.
- a core network element specially set up for collecting terminal device information can make the function of the network element relatively independent, so that the operation efficiency of the network element is higher.

That is, the first core network element can be used not only to collect information of terminal devices, but also to perform other functions. On the one hand, this can reduce the number of core network elements set up, thereby reducing the network deployment cost of the communication system.
- the first core network element may be a core network element that needs to be selected during the establishment of a PDU session.
