[0026] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0027] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0028] Please refer to FIG1 , which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 may include: a terminal device 10 , an access network device 20 , and a core network element 30 .

For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art may understand its meaning.

[0030] The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, APs (Access Points), etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR (New Radio) system, it is called gNodeB or gNB (Next Generation Node B). With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between the terminal device 10 and the core network network element 30 through the access network device 20. For example, in an LTE (Long Term Evolution) system, the access network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs in the EUTRAN. In a 5G NR system, the access network device 20 may be a Radio Access Network (RAN) or one or more gNBs in the RAN. In the embodiments of the present application, unless otherwise specified, the "network device" referred to refers to the access network device 20, such as a base station.

[0031] The core network element 30 is a network element deployed in the core network. The functions of the core network element 30 are mainly to provide user connection, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network elements in the 5G NR system may include network elements such as the AMF (Access and Mobility Management Function) entity, the UPF (User Plane Function) entity, and the SMF (Session Management Function) entity.

[0032] In some embodiments, the access network device 20 and the core network element 30 communicate with each other via an air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0033] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (e.g., B5G (Beyond 5G) systems, 6G systems (6th Generation System, sixth generation mobile communication systems)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, which are not limited in this application.

[0034] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0035] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0036] Ambient-powered IoT devices, such as low-power sensors and passive tags, generally lack a stable energy supply like mains electricity or long-lasting batteries. Instead, they rely on harvested ambient energy (including but not limited to light, heat, mechanical, and electromagnetic energy) to power their circuits and interact with the outside world. The key advantage of this design approach is that deployment locations are not restricted by power lines, and regular battery replacement is unnecessary, allowing for compact devices. The lack of a power supply also improves reliability, extending device lifespan and reducing overall system construction and maintenance costs. On the other hand, the total amount and efficiency of harvested ambient energy are limited by the scenario and device size, typically in the microwatt to milliwatt range. This limits the complexity of the device's processing circuitry, transmission power, and communication range. Furthermore, some energy harvesting technologies, such as electromagnetic wave energy harvesting, require a long time to harvest and store enough energy for data collection and communication due to low ambient energy levels. Consequently, they cannot operate continuously, for example, reporting information only once every few hours. In summary, environmentally powered IoT technology is more suitable for application scenarios with a large number of devices within a limited range that require long life, low cost, and maintenance-free automatic operation, such as natural environment monitoring, factory safety production, warehousing and logistics retail, and item positioning and tracking, and complements IoT devices powered by mains electricity or batteries.

[0037] Among various environmental energies, energy supply methods such as light energy, heat energy, and mechanical energy are often subject to environmental restrictions. For example, they require energy sources that are limited in time or location, such as sunlight or light exposure, running mechanical equipment, and heat generated by the operation of other equipment, and their deployment is restricted. Electromagnetic wave energy supply only requires a certain amount of electromagnetic wave power in an appropriate frequency band such as 900MHz. When necessary, a radio frequency energy supply device can be deployed to achieve radio frequency energy collection, so it can be deployed more widely. This application mainly discusses electromagnetic wave energy supply methods, and the main invention points are also applicable to other energy supply methods.

[0038] Figure 2 illustrates the operation of a wireless IoT system using electromagnetic wave energy harvesting. The energy generator is an optional device, deployed when the RF energy emitted by the controller is insufficient. At this point, the interaction between the controller and IoT devices primarily involves communication (control signaling and data transmission). The electromagnetic wave frequencies used for communication and RF energy transmission can be the same or different. An example application scenario involves using the 2.4 GHz ISM (Industrial Scientific Medical) unlicensed frequency band for communication and the 900 MHz frequency band for RF energy transmission. Note that due to compliance requirements for electromagnetic radiation safety, the transmission power of the controller and energy generator cannot be increased indefinitely and must meet the restrictions and requirements of national regulations.

[0039] For IoT systems that harvest electromagnetic wave energy, electromagnetic waves attenuate as the propagation distance increases due to their propagation characteristics. Obstacles in the deployment environment, such as walls and surrounding objects, also cause penetration loss and losses due to electromagnetic wave refraction, reflection, and scattering. Environmental energy harvesting IoT devices deployed in different locations have different paths between their locations and the relatively fixed controllers and energy suppliers, resulting in different energy losses in electromagnetic wave propagation. Their energy harvesting efficiency and the minimum uplink transmission power required to ensure reliable signal transmission to the controller (to overcome the impact of path loss) are also different.

[0040] As mentioned above, three possible IoT work scenarios are analyzed:

[0041] 1. The power supply for IoT devices is sufficient or relatively sufficient:

[0042] a) Connect to mains power. In this case, the equipment can continue to operate and energy saving does not need to be a priority;

[0043] b) Devices with large internal batteries—for example, nb-IoT (Narrow Band Internet of Things) technology. These devices can operate as designed throughout their lifecycle (for example, with a low duty cycle to conserve energy and extend battery life) without having to consider harvesting ambient energy.

[0044] 2. IoT devices lack energy storage and rely on readers / power supplies to provide sufficient energy for timely communication. A typical example is passive RFID (Radio-Frequency Identification) tags. In this case, the device circuitry can only be powered and operational when the reader / power supply begins emitting electromagnetic waves (typically continuous waves). The operating range is short (dependent on the reader's transmit power, antenna gain, and receiver sensitivity, and the tag's circuit power consumption and antenna gain and receiver sensitivity, typically on the order of ~10 meters). There's no need for a long energy accumulation process; upon receiving the electromagnetic waves from the reader / power supply, the circuitry can immediately activate and begin operating. Devices outside the coverage area are inoperative (in a dormant state).

[0045] 3. Between scenarios 1 and 2: The IoT device is not connected to a reliable power source and has a limited energy storage device (such as a small energy storage capacitor or a small-capacity rechargeable battery); the device is far away from the reader, and the reader / controller is subject to legal and regulatory restrictions, with limited transmission power (this may be relaxed appropriately in industrial application scenarios), making it difficult to increase the range or power level of wireless power supply. As a result, the RF (Radio-Frequency) energy emitted by the reader is insufficient to support real-time reading and writing operations, requiring the use of pre-collected ambient energy for storage (this patent only considers RF power supply methods using readers, energizers, etc., and other energy collection methods such as solar energy, thermal energy, and mechanical vibration energy are not discussed). One possible working scenario is that the communication distance of devices such as sensors is long, and the actual working characteristics determine that frequent reading and writing are not required, allowing the device to accumulate energy over a long period of time to support information interaction on a cycle of hours or days, or information transmission triggered by occasional events.

[0046] Please refer to FIG3 , which shows a flow chart of a registration method for an environmental energy supply device provided in one embodiment of the present application. The method is executed by the environmental energy supply device and includes the following step 310 .

[0047] Step 310: The environment energy supply device sends first information to the first control device. The first information is used to request access to the first control device. The first control device is used to exchange information with the environment energy supply device.

[0048] Correspondingly, the first control device receives the first information sent by the environmental energy supply device.

[0049] In some embodiments, the ambient energy supply device obtains the required power through multiple ambient energy sources (micro-light energy, radio frequency energy, micro-kinetic energy, and temperature difference energy). Micro-energy management technology optimizes and stores the collected energy, ultimately achieving a self-powered state. For example, the ambient energy supply device can be a passive tag, such as an RFID.

[0050] In some embodiments, the first control device is configured to exchange information with the environmental energy supply device. For example, the environmental energy supply device is configured to collect environmental information, such as humidity, temperature, and other environmental data, and the first control device is configured to read the environmental information collected by the environmental energy supply device. For example, the first control device may be a reader.

[0051] In some embodiments, the first control device is further configured to provide energy to the environment energy supply device. For example, the first control device sends a wireless signal for supplying energy to the environment energy supply device, and the environment energy supply device receives the wireless signal and obtains energy.

[0052] In some embodiments, the first control device is further configured to control at least one energy supply device, which is configured to provide energy to the ambient energy supply device. For example, the first control device controls at least one functional device to transmit a wireless signal for energy supply to the ambient energy supply device, which then receives the wireless signal and obtains energy. In some embodiments, the energy supply device is specifically configured to transmit wireless signals for energy supply.

[0053] In some embodiments, when the energy level of the ambient energy supply device reaches a second threshold, the ambient energy supply device transmits the first information to the first control device. In some embodiments, the second threshold is a preset threshold value. In some embodiments, the second threshold value may be predefined, preconfigured, or determined by the ambient energy supply device based on its own implementation, which is not limited in this application.

[0054] In some embodiments, the first information includes at least one of the following: access type, identification information of the ambient energy supply device, energy level of the ambient energy supply device, timestamp information of the ambient energy supply device, and sleep time of the ambient energy supply device.

[0055] In some embodiments, the access type refers to the type of access of the environmental energy supply device to the first control device. Exemplarily, the access type may include initial access. For example, the process of accessing the first control device when the environmental energy supply device is first put into use is called initial access.

[0056] In some embodiments, the identification information of the environment energy supply device is used to uniquely identify the environment energy supply device. For example, the identification information of the environment energy supply device can be the ID (Identity Document) of the environment energy supply device, or can be determined based on the ID of the environment energy supply device.

[0057] In some embodiments, the energy level of the ambient power supply refers to the energy stored by the ambient power supply.

[0058] In some embodiments, the timestamp information of the ambient energy supply device refers to the time of a clock maintained locally by the ambient energy supply device. In some embodiments, to reduce the energy required to send the first information, the timestamp information of the ambient energy supply device may be a truncated time. For example, the timestamp information of the ambient energy supply device may include only minute and second information.

[0059] In some embodiments, to further reduce energy consumption of the environment energy supply device, the environment energy supply device enters a dormant state after sending the first information to the first control device.

[0060] In some embodiments, the first information also includes the sleep time of the environment power supply device. In some embodiments, the sleep time of the environment power supply device can be the length of the sleep time of the environment power supply device, or it can be the time when the environment power supply device wakes up after sleeping, which is not limited in this application.

[0061] In some embodiments, the sleep time of the environmental energy supply device can be in time units (such as minutes or seconds) or in units of the broadcast cycle of the first control device, which is not limited in this application. The broadcast cycle of the first control device refers to the period during which the first control device sends broadcast information. Exemplarily, the sleep time of the environmental energy supply device is 50s. Exemplarily, the sleep time of the environmental energy supply device is 127 broadcast cycles.

[0062] The technical solution provided in the embodiment of the present application is to send a first message for requesting access to the first control device through the environmental energy supply device to the first control device, so that the environmental energy supply device can establish an association relationship with the first control device. The first control device can manage the environmental energy supply device based on the association relationship established with the environmental energy supply device, which can effectively avoid problems such as the loss of the environmental energy supply device.

[0063] In some embodiments, after receiving the broadcast information sent by the first control device, the environment energy supply device sends the first information to the first control device based on the broadcast information.

[0064] In some embodiments, before step 310 , the method further includes at least one of the following steps 320 to 330 .

[0065] Step 320: The environmental energy supply device receives broadcast information sent by at least one control device, where the broadcast information is periodic information.

[0066] In some embodiments, the at least one control device includes a first control device.

[0067] In some embodiments, when the energy level of the environment power supply device reaches a first threshold, the environment power supply device receives broadcast information respectively sent by at least one control device.

[0068] In some embodiments, the first threshold is a preset threshold value. In some embodiments, the first threshold value may be predefined, preconfigured, or determined by the environmental energy supply device based on its own implementation, which is not limited in this application. In some embodiments, the first threshold value is greater than or equal to the second threshold value.

[0069] In some embodiments, the broadcast information includes at least one of the following: broadcast period, timestamp information of the broadcast information, broadcast message sequence number of the broadcast information, maximum value of the broadcast message sequence number, receiving capability of the control device, and transmission power of the broadcast information.

[0070] In some embodiments, the broadcast cycle refers to the cycle in which the first control device sends broadcast information. In some embodiments, the timestamp information of the broadcast information refers to the time information of sending the broadcast information, such as the time when the broadcast information is sent. In some embodiments, the broadcast message sequence number of the broadcast information refers to the sequence number of the broadcast information. Exemplarily, the first control device sends broadcast information 1 and broadcast information 2, which means that there is a broadcast cycle between the two broadcast messages, and broadcast information 1 is sent first. In some embodiments, the broadcast message sequence number of the broadcast information can also be called the timestamp sequence number of the broadcast information. Within a period of time, different broadcast information has different broadcast message sequence numbers, which are used to characterize the sending timing of the broadcast information within the period of time.

[0071] In some embodiments, because broadcast messages are sent periodically, maintaining an infinite broadcast message sequence number is unrealistic. Therefore, a maximum broadcast message sequence number can be specified. Upon reaching the maximum broadcast message sequence number, the broadcast message sequence number corresponding to the next broadcast message is renumbered starting from the minimum broadcast message sequence number. For example, if the maximum broadcast message sequence number is 10 and the minimum broadcast message sequence number is 1, then if the first broadcast message has a broadcast message sequence number of 10, the broadcast message sequence number corresponding to the next broadcast message is renumbered starting from 1.

[0072] In some embodiments, the receiving capability of the control device refers to the minimum receiving power at which the control device can correctly parse information.

[0073] Step 330: The environment energy supply device determines a first control device from the at least one control device based on the broadcast information respectively sent by the at least one control device.

[0074] Accordingly, the first control device sends broadcast information to the environmental energy supply device.

[0075] In some embodiments, step 330 includes at least one of the following steps 331 - 332 .

[0076] Step 331: The environmental energy supply device determines the path loss corresponding to each piece of broadcast information based on the transmit power corresponding to each piece of broadcast information.

[0077] In some embodiments, for any one of the broadcast information, the environment energy supply device determines the path loss corresponding to the broadcast information based on the transmission power of the broadcast information.

[0078] In some embodiments, for any one of the broadcast information, the environment energy supply device determines the path loss corresponding to the broadcast information based on the transmission power of the broadcast information and the reception power of the broadcast information.

[0079] Step 332: The environmental energy supply device determines a first control device from at least one control device based on the path losses corresponding to each broadcast information, and determines the transmission power of the first information.

[0080] In some embodiments, the environmental energy supply device determines the control device corresponding to the broadcast information with the smallest path loss as the first control device based on the path losses corresponding to the respective broadcast information. This can reduce the transmission power of the first information and reduce the energy required by the environmental energy supply device to send the first information.

[0081] In some embodiments, the environmental energy supply device determines the first control device from the at least one control device based on the path losses corresponding to the respective broadcast information and the received powers corresponding to the respective broadcast information.

[0082] In some embodiments, based on the path losses corresponding to the respective broadcast messages, the environmental energy supply device determines the control device corresponding to the broadcast message with the highest received power among H broadcast messages with the smallest path losses as the first control device, where H is a positive integer. This reduces the transmit power of the first message and the energy required by the environmental energy supply device to transmit the first message, while also ensuring the stability of subsequent information exchange between the environmental energy supply device and the first control device.

[0083] In some embodiments, after determining the first control device, the environmental energy supply device determines the minimum transmit power of the first information based on the path loss corresponding to the first control device and the receive capability of the control device carried in the broadcast information sent by the first control device. In some embodiments, the minimum transmit power of the first information is greater than or equal to the sum of the path loss corresponding to the first control device and the receive capability of the first control device. In some embodiments, the transmit power of the first information is greater than or equal to the minimum transmit power of the first information.

[0084] In some embodiments, step 330 further includes the following step 333 .

[0085] Step 333: The environmental energy supply device calibrates the local clock based on the timestamp information of the broadcast information.

[0086] In some embodiments, since the environment power supply device is in a dormant state when the energy does not reach a certain threshold, and the environment power supply device is not communicated with the network device, the local clock of the environment power supply device cannot be aligned with the clock of the network device, so the clock maintained locally by the environment power supply device may be offset.

[0087] In some embodiments, the environmental energy supply device determines the time information maintained by the control device corresponding to the broadcast information based on the timestamp information of the broadcast information, and then calibrates the local clock.

[0088] In some embodiments, the above step 310 can be implemented as the following step 311 .

[0089] Step 311: If M broadcast messages are successfully parsed among the N consecutive broadcast messages sent by the first control device received by the environmental energy supply device, the first message is sent to the first control device, where M is a positive integer less than or equal to N and N is a positive integer.

[0090] In some embodiments, the broadcast information sent by the control device and received by the environmental energy supply device may fail to be parsed due to various reasons. For example, the receiving power of the broadcast information is too low, resulting in failure to successfully parse. Similarly, unsuccessful parsing may also occur in other interactive information between the environmental energy supply device and the control device. Therefore, before sending the first information to the first control device, it is first necessary to determine the probability that the information interaction between the environmental energy supply device and the first control device may fail to be parsed.

[0091] In some embodiments, N and M are pre-set. In some embodiments, N and M may be pre-defined, pre-configured, or determined based on the implementation of the ambient energy supply device itself, which is not limited in this application.

[0092] Through the above method, a method for an environmental energy supply device to determine a first control device is provided, so that the environmental energy supply device can determine a suitable control device among multiple control devices, while ensuring the stability of information interaction between the environmental energy supply device and the first control device.

[0093] In some embodiments, after receiving the first information, the first control device sends second information to the environmental energy supply device, where the second information is used to approve the access request of the environmental energy supply device, or the second information is used to reject the access request of the environmental energy supply device.

[0094] In some embodiments, after step 310 , the method further includes the following step 340 .

[0095] Step 340: The environment energy supply device receives the second information sent by the first control device. The second information is used to approve the access request of the environment energy supply device, or the second information is used to reject the access request of the environment energy supply device.

[0096] Accordingly, the first control device sends the second information.

[0097] In some embodiments, the first information includes timestamp information of the ambient energy supply device. After receiving the first information, the first control device determines a clock offset of the ambient energy supply device based on the timestamp information of the ambient energy supply device and the timestamp information of the first control device.

[0098] In some embodiments, the first control device sends the second information to the ambient energy supply device based on the clock offset of the ambient energy supply device to improve the success rate of the ambient energy supply device receiving the second information.

[0099] In some embodiments, after receiving the first information, the first control device establishes and maintains local identification information of the environmental energy supply device.

[0100] In some embodiments, in order to reduce the storage pressure of the first control device, local identification information of the environmental energy supply device can be established and maintained locally on the first control device. In some embodiments, the local identification information of the environmental energy supply device is associated with the identification information of the environmental energy supply device. In some embodiments, the local identification information of the environmental energy supply device can be obtained by performing a variant based on the identification information of the environmental energy supply device. Exemplarily, the identification information of the environmental energy supply device is the ID of the environmental energy supply device, and the local identification information of the environmental energy supply device can be a variant of the ID of the environmental energy supply device, such as a hash value.

[0101] In some embodiments, the environment energy supply device goes into sleep mode after sending the first information, and after waking up from sleep mode, receives the second information sent by the first control device.

[0102] In some embodiments, the first control device may send the second information multiple times to improve the success rate of the environmental energy supply device receiving the second information.

[0103] In some embodiments, the time-frequency resource used by the first control device to send the second information is preset. In some embodiments, the first control device sends the second information on a fixed time-frequency resource. In some embodiments, the fixed time-frequency resource may be predefined or preconfigured, which is not limited in this application.

[0104] In some embodiments, the time-frequency resources for transmitting the second information by the first control device are determined based on the identification information of the environmental energy supply device. For example, a mapping relationship exists between the identification information of the environmental energy supply device and the time-frequency resources for transmitting the second information. In some embodiments, this mapping relationship may be predefined or preconfigured, and this application does not limit this.

[0105] In some embodiments, if the second information is used to agree to the access request of the environmental power supply device, the second information includes at least one of the following: an access confirmation command, local identification information of the environmental power supply device, timestamp information of the first control device, power control information, MCS (Modulation and Coding Scheme) adjustment information, and key exchange information.

[0106] In some embodiments, the local identification information of the environmental energy supply device may be the same as or different from the identification information of the environmental energy supply device, and this application does not limit this.

[0107] In some embodiments, to reduce the amount of data in the second information, the access confirmation command and / or the access rejection command may be a predefined binary field. For example, if the value of the information field is 1, it indicates an access confirmation command, and if the value of the information field is 0, it indicates an access rejection command.

[0108] In some embodiments, the amount of data in the second information may also be used to determine whether the second information is used to approve or reject the access request of the environmental energy supply device. For example, if the amount of data in the second information is greater than a third threshold, the second information is used to approve the access request of the environmental energy supply device; if the amount of data in the second information is less than the third threshold, the second information is used to reject the access request of the environmental energy supply device.

[0109] In some embodiments, whether the second information is used to approve or reject the access request of the environment power supply device can be determined based on the value of one or more information fields in the power control information, the MCS adjustment information, and the key exchange information. Exemplarily, the value of the information field where the power control information is located is 0, indicating that the second information is used to reject the access request of the environment power supply device. Exemplarily, the value of the information field where the MCS adjustment information is located is 0, indicating that the second information is used to reject the access request of the environment power supply device. Exemplarily, the value of the information field where the key exchange information is located is 0, indicating that the second information is used to reject the access request of the environment power supply device.

[0110] In some embodiments, if the second information is used to approve the access request of the environment energy supply device, the method further includes at least one of the following steps 350 to 380 .

[0111] Step 350: The environmental energy supply device calibrates the local clock according to the timestamp information of the first control device.

[0112] Step 360: The environmental energy supply device adjusts the transmission power of the third information according to the power control information, where the third information is used for information interaction with the first control device.

[0113] In some embodiments, the third information may be any piece of interactive information between the environment energy supply device and the first control device.

[0114] Step 370: The environmental energy supply device adjusts the modulation and coding scheme of the third information according to the MCS adjustment information.

[0115] In some embodiments, the MCS adjustment information is used to indicate a modulation scheme and / or coding scheme of the third information.

[0116] In step 380 , the environmental energy supply device encrypts the data according to the key exchange information.

[0117] In some embodiments, if the second information is used to reject the access request of the environment power supply device, the second information includes at least one of the following: an access rejection command, identification information of the environment power supply device, and timestamp information of the first control device.

[0118] In some embodiments, if the first control device rejects the access request of the environmental energy supply device, there is no need to maintain the local identification information of the environmental energy supply device. Therefore, if the second information is used to reject the access request of the environmental energy supply device, the second information does not include the local identification information of the environmental energy supply device, but includes the identification information of the environmental energy supply device.

[0119] In some embodiments, if the second information is used to reject the access request of the environment energy supply device, the method further includes the following step 390 .

[0120] In step 390 , the environmental energy supply device sends fourth information to the second control device. The fourth information is used to request access to the second control device. The second control device and the first control device are different control devices.

[0121] In some embodiments, when there is no second control device, or when there is no control device that agrees to the access request of the environment power supply device, the environment power supply device enters a dormant state, and the second control device and the first control device are different control devices.

[0122] In some embodiments, if the environment energy supply device fails to find a second control device that meets the conditions, or all control devices reject the access request of the environment energy supply device, the environment energy supply device enters a dormant state.

[0123] In some embodiments, when the energy level of the ambient power device reaches a first threshold, or when the energy level of the ambient power device reaches a second threshold, the ambient power device may wake up and re-execute the above process.

[0124] Through the above method, the environmental energy supply device can determine whether to access the first control device, reselect other control devices, or enter a sleep state based on the second information sent by the first control device, thereby avoiding the loss of the environmental energy supply device when it cannot access the control device.
