[0040] The following is an explanation of the terms used in the embodiments of the present application.

[0041] 1. Ambient IoT (AIoT)

[0042] Ambient IoT is a new 3GPP IoT technology. Ambient IoT devices have ultra-low complexity and ultra-low power consumption.

[0043] Ambient IoT, also known as ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an IoT service in which IoT devices obtain energy from the environment through energy harvesting, reducing the need to replace batteries or recharge. Energy sources for energy harvesting include radio waves, light, motion, heat or other suitable energy sources.

[0044] The energy of Ambient IoT devices comes from energy harvesting. Regarding energy storage, the device can have the following characteristics:

[0045] -No batteries, no energy storage. Completely dependent on external energy sources. Or,

[0046] - Limited energy storage capabilities, e.g. using capacitors to store energy.

[0047] Ambient IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc. It should be noted that Ambient IoT may include Passive IoT.

[0048] In the overall architecture of Ambient IoT accessing the 3GPP communication network, UE or RAN can be used as a reader to obtain data from the Ambient IoT device and transmit it to the Ambient IoT application server.

[0049] 2. IoT Terminals

[0050] IoT terminals generally refer to terminal devices used in certain specific scenarios or for specific services. IoT devices can be optimized for the specific needs of the services and applications to be performed (for example, smart homes / cities, smart utilities, e-health, and smart wearable devices).

[0051] 3. RFID tags

[0052] Radio Frequency Identification (RFID) tags can be considered as an environmental IoT terminal. RFID readers can use radio waves to read information from RFID tags.

[0053] Radio frequency identification technology can be divided into three types: active, passive and semi-active. Passive tags can also be called passive IOT, that is, passive IoT devices. The communication method of RFID devices can be based on backscattered RF signals for signal transmission (BSC); or, some RFID devices also have the ability to generate active signals. Because the energy of RFID devices can come from the environment, such as wireless signals, solar energy, thermal energy, wind energy, kinetic energy, etc., it can also be considered as an ambient IoT (Ambient IoT, AIOT) device.

[0054] 4. Reading and writing equipment

[0055] A read / write device is a device that reads information from a low-power device and can optionally write information to a low-power device. It can also be understood as a device that communicates with a low-power device or as an access point for a low-power device to access a wireless communication system. A read / write device can be a terminal, a base station, or a device with read / write functions, such as a reader / writer, which is not specifically limited here.

[0056] The 5G system includes terminals, access networks, and core networks. The 5G system provides a data channel between the terminal and the data network, allowing the terminal to access services in the data network. The terminal accesses the 5G core network, which can perform access control, authentication, and provide communication services to the terminal based on the terminal's identity and corresponding contract data.

[0057] Currently, in RFID technology, the distance between the reader and the tag needs to be relatively close to work. The 3GPP standard organization is discussing how to enable the IoT server to communicate with environmental IoT devices through the 3GPP network, for example, to control environmental IoT devices.

[0058] In an embodiment of the present application, after the first network element in the communication network receives the first control request message, the first network element sends a first message, and the functions of the first message include at least one of the following: triggering the acquisition of identification information of the IoT device, triggering the first control of the IoT device. In this way, through this method, when it is necessary to control the IoT device, the first message can be sent through the first network element to trigger the acquisition of identification information of the IoT device or trigger the first control of the IoT device, so that the IoT app can control the IoT device through the first network element in the network. In this way, the first network element can assist in the control of the IoT device, thereby improving the coverage of the network architecture including the IoT device, and supporting large-scale cellular network deployment, massive IoT devices and seamless coverage.

[0059] The following is a detailed description of the IoT device control method provided by the embodiment of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0060] Figure 2 A flowchart of the method for controlling an IoT device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method may include the following steps S201 and S202:

[0061] Step S201: A first network element receives a first control request message.

[0062] The first control request message is used to request a first control of the IoT device.

[0063] Optionally, in an embodiment of the present application, the above-mentioned first network element may be an AMF (Access and Mobility Management Function).

[0064] Optionally, in an embodiment of the present application, the above-mentioned Internet of Things device may be an environmental Internet of Things device, which may also be referred to as an environment-enabled Internet of Things device (ie, an AIOT device).

[0065] Optionally, in this embodiment of the present application, the first control request message includes at least one of the following:

[0066] Regional information of the area where the IoT device is located;

[0067] Device service identification of IoT devices;

[0068] The device group service identifier corresponding to the IoT device;

[0069] The control type corresponding to the first control.

[0070] The first control cycle;

[0071] The frequency of the first control.

[0072] Exemplarily, the above-mentioned area information describes the area where the AIOT device to be controlled is located.

[0073] Exemplarily, the device service identifier is used to identify the AIOT device in the AIOT App, that is, to indicate that the control operation is performed on the target AIOT device.

[0074] Exemplarily, the device group service identifier is used to identify a group of AIOT devices in the AIOT App. The AIOT device group can be pre-set by the operator or AIOT App, or can be used to describe a type of AIOT device, such as inventory type, sensor type, positioning type, and control type.

[0075] Exemplarily, the above control type includes at least one of the following: inventory, activation, deactivation, reading, writing, pushing data, and deleting data.

[0076] Exemplarily, the above-mentioned first control period or first control frequency can be carried in a Next Generation Application Protocol (NGAP) message or a Non Access Stratum (NAS) message to instruct the read-write device to repeatedly send device control information to the AIOT device according to the period or frequency.

[0077] In an embodiment of the present application, the first network element can receive at least one of the area information, device service identifier, device group service identifier, control type, period of device control command, and frequency of device control command of the IoT device sent by the IoT server, and send the first information based on the above, so as to accurately perform corresponding control operations on the IoT device that needs to communicate.

[0078] Optionally, in an embodiment of the present application, the first network element may receive a first control request message from the AIOT server. For example, taking the first network element as AMF as an example, the AIOT App may send the first control request message to the AMF in one of the following ways:

[0079] Send a control request message to AMF through the Network Exposure Function (NEF);

[0080] Send control request messages to AMF through NEF and Unified Data Management (UDM) network elements;

[0081] A control request message is sent to AMF through NEF and AIOT NF (Network Function).

[0082] Optionally, in an embodiment of the present application, when sending the first control request message, the first control request message is authorized by the NEF. For example, the NEF confirms whether the AIOT App is allowed to make a control request and whether the AIOT App is allowed to control the AIOT device in the control request message.

[0083] It should be noted that when the AIOT control request message is forwarded through an intermediate network element (such as NEF or other NF), the parameters therein may change. For example, the regional parameter sent by the AIOT App may be the geographic location, and the regional parameter received by the AMF may be the location information within the operator's network. The AIOT device service identification parameter sent by the AIOT App may be the identification parameter of the AIOT device in the operator's network received by the AMF.

[0084] Optionally, in an embodiment of the present application, the first control includes at least one of the following: inventory, reading, writing, data transmission, pushing, activation, deactivation, and data deletion.

[0085] It should be noted that the above-mentioned first control may also be other controls, which is not limited in the embodiments of the present application.

[0086] In an embodiment of the present application, the first network element can control at least one of inventory, reading, writing, data transmission, push, activation, deactivation and data deletion of the Internet of Things device, thereby improving the efficiency of inventory, data reading and writing and other operations of the Internet of Things device.

[0087] Step S202: The first network element sends first information, wherein the first information is used for at least one of the following:

[0088] Trigger the acquisition of identification information of IoT devices,

[0089] Trigger the first control of the IoT device.

[0090] Optionally, in the embodiment of the present application, the first information includes at least one of the following:

[0091] Device control information;

[0092] Device control type;

[0093] Device identification information of IoT devices;

[0094] The sending cycle of device control information;

[0095] The frequency with which device control information is sent;

[0096] A device control transaction identifier, where the device control transaction identifier is used to mark the device control process corresponding to the first information;

[0097] The device control information is used for at least one of the following:

[0098] Get the identification information of IoT devices,

[0099] Take first control over IoT devices.

[0100] Exemplarily, the above-mentioned device control type (ie, AIOT command type), corresponding to the control type, includes one of the following: inventory, activation, deactivation, reading, writing, pushing data, and deleting data.

[0101] Exemplarily, the above-mentioned device control information may be a device control command, which may be expressed as an AIOT NAScommand. The AIOT control request command encapsulated by the protocol stack (e.g., NAS) between the AIOT device and the AMF may include at least one of the AIOT command type and the AIOT command content.

[0102] Exemplarily, the AIOT command content may include at least one of the following: a security parameter corresponding to the AIOT command, a read parameter, a write parameter, a write parameter content, and a period / frequency of the AIOT command.

[0103] Part or all of the parameters in the device control information may be encrypted using a pre-configured key, a key negotiated with the AIOT device, or a key negotiated with the AIOT service provider. Optionally, the encrypted parameters are not visible to the reader, for example, the reader cannot decrypt the encrypted parameters.

[0104] Exemplarily, the sending period or the sending frequency of the device control information, that is, the AIOT command period / frequency, can be carried in the NGAP or NAS message, so that the reader repeatedly sends the AIOT NAScommand part to the AIOT device according to the period or frequency.

[0105] Exemplarily, device identification information, such as AIOT device identification information, is used to identify one or a group of AIOT devices in AMF and reader. The device identification information may include at least one of the following: AIOT device identification (i.e., AIOT device ID), AIOT device group identification (i.e., AIOT device group ID).

[0106] It should be noted that the AIOT device ID and AIOT device group ID correspond to the AIOT device service identifier and AIOT device group service identifier respectively, and the two can be the same or different. In the case where the two are different, AMF can determine the AIOT device identification information based on the stored relationship between the two and the AIOT device service identifier or AIOT device group service identifier.

[0107] Optionally, the AIOT device group ID may be a part of the AIOT device ID. The AIOT device type may also be a part of the AIOT device ID.

[0108] Optionally, the AIOT device identification information may be allocated by the read / write device to the AIOT device.

[0109] In a possible implementation, the AMF may determine the AIOT device identification information according to the AIOT device service identifier. The AMF sends a control request message to the reader, including the AIOT device identification information.

[0110] In another possible implementation, AMF sends a control request message to the reader, in which the AIOT device service identifier is a null value. The reader sends a control request message to the AIOT device, and after receiving a response from the AIOT device, allocates an AIOT device ID to the AIOT device and sends the AIOT device ID to AMF.

[0111] It should be noted that the AIOT device service identifier may be null. This may happen when AMF sends a control request message to the AIOT device for the first time, because AMF does not know how to mark the AIOT device on the reader. Or, AMF does not know which AIOT devices are within the reader's coverage. Or, the AIOT App's request is an inventory request, the purpose of which is to obtain the identification information of the AIOT device.

[0112] Exemplarily, the device control transaction identifier, ie, the AIOT NAS transaction ID, is used to mark the AIOT NAS command message, the AIOT NAS command process, the core network control request message, or the core network control request process.

[0113] In an embodiment of the present application, the first network element can send information such as device control information, device control type, or device identification information of the Internet of Things device to trigger the acquisition of identification information of the Internet of Things device or trigger the first control of the Internet of Things device, thereby accurately controlling the Internet of Things device that needs to be controlled.

[0114] Optionally, in an embodiment of the present application, the above-mentioned device control information is encapsulated through a specific communication protocol between the Internet of Things device and the first network element.

[0115] Optionally, in an embodiment of the present application, the above-mentioned device control information is information encrypted using a pre-configured key.

[0116] Optionally, in the embodiment of the present application, the device control information includes at least one of the following:

[0117] The control type corresponding to the device control information,

[0118] Security parameters corresponding to device control information,

[0119] The read parameters corresponding to the device control information,

[0120] Write parameters corresponding to device control information,

[0121] Write parameter content corresponding to the device control information,

[0122] The control cycle of the device control information,

[0123] The control frequency of the device control information.

[0124] In an embodiment of the present application, a first information is sent through a first network element to trigger the acquisition of identification information of the IoT device or to trigger a first control of the IoT device, thereby enabling the IoT server to control the IoT device through the first network element in the wireless network. In this way, the first network element can assist in the control of the IoT device, thereby improving the coverage of the network architecture including the IoT devices, and supporting large-scale cellular network deployment, massive IoT devices and seamless coverage.

[0125] Optionally, in the embodiment of the present application, the above step S202 can be implemented by the following step S202a.

[0126] Step S202a: The first network element sends first information to the read-write device.

[0127] Among them, the functions of the above-mentioned first information include at least one of the following: triggering the read-write device to obtain the identification information of the Internet of Things device, and triggering the read-write device to perform a first control on the Internet of Things device.

[0128] Optionally, in an embodiment of the present application, the first network element may determine the read / write device according to the parameter information in the received first control request message, and send the first information to the read / write device. Optionally, the AMF may also determine the read / write device according to the reader / writer information corresponding to the IoT device.

[0129] Optionally, in an embodiment of the present application, the above-mentioned reading and writing device may be a terminal device (ie, UE) or a base station (ie, RAN).

[0353]

[0354] When executing step 13, the reader sends an inventory message to the AIOT device, the AIOT NAS command part can be omitted or set to empty.

[0355] Step 16: The AIOT device sends an AIOT NAS command response to the reader.

[0356] Exemplarily, the NAS command response is an AIOT control response encapsulated by a protocol stack (e.g., NAS) between the AIOT device and the AMF, including at least one of an AIOT command response type and an AIOT command response content.

[0357] Exemplarily, the AIOT command response content includes at least one of the following: the processing result of the AIOT device on the AIOT NAS command, the reason value, the read result, the write result, the AIOT command cycle / frequency, the AIOT device identification information, the service identification of the AIOT device, and the service identification of the AIOT device group. Optionally, some or all of the parameters can be encrypted using a pre-configured key or a key negotiated with the core network.

[0358] Optionally, the AIOT device may also send at least one of the AIOT device identification information and the AIOT NAS transaction ID to the reader.

[0359] For example, the message format of AIOT device->reader is as follows:

[0360]

[0361] It is worth noting that the messages in steps 14 and 16 can be combined into a unified message format:

[0362]

[0363] Among them, when the AIOT device sends an inventory response to the reader, the AIOT NAS command response part can be omitted or set to empty.

[0364] It is worth noting that the reader can determine which AIOT NAS command the AIOT NAS command response is associated with based on the AIOT NAS transaction ID parameter, and then send an AIOT NAS command response to the AMF that sent the AIOT NAS command.

[0365] Step 17: The reader sends the AIOT NAS command response to the AMF.

[0366] Optionally, the reader also sends AIOT command response type and AIOT device identification information to AMF, where AIOT command response type indicates the type of the AIOT command to be responded to, corresponds to AIOT command type, can be the same as AIOT command type, or can indicate a response to AIOT command type.

[0367] For example, the message format of reader->AMF is as follows:

[0368] RAN reader:

[0369]

[0370] UEreader:

[0371]

[0372]

[0373] It is worth noting that AMF can determine which AIOT NAS command the AIOT NAS command response is associated with based on the AIOT NAS transaction ID parameter.

[0374] Step 18: AMF sends a control AIOT response message to the AIOT App.

[0375] The AIOT response message includes at least one of the following parameters: region, AIOT device service identifier, AIOT device group service identifier, and response type.

[0376] Exemplarily, AMF may send a control response message to the AIOT App in one of the following ways:

[0377] A) Send a control request message to the AIOT App through the capability exposure platform NEF.

[0378] B) Send control request messages to AIOT App through NEF and UDM.

[0379] C) Send control request message to AIOT App through NEF and AIOT NF.

[0380] In a possible implementation, step 13 and step 14 are omitted. After step 12, the reader sends an AIOT NAS command to the AIOT device. At this time, the reader can broadcast or send the AIOT NAS command in a group manner. The AIOT device that receives the AIOT NAS command can determine whether it needs to process the message based on the AIOT device identifier in the message. Exemplarily, if the AIOT device identifier matches its own identifier, the AIOT device executes step 16.

[0381] Embodiment 2:

[0382] There is an independent protocol stack between the AIOT device and AMF to encapsulate the command signaling to the AIOT device and the corresponding response message of the AIOT device;

[0383] AMF receives the request from the App and sends an encapsulated control command to the AIOT device. AMF sends the encapsulated control command to the reader. The inventory command is also encapsulated and executed by the core network. The message sent by the reader to the device is a unified command + Tag ID + Tag group ID. After the device receives the message from the reader, it first checks whether the Tag ID and Tag group ID point to itself (or default, indicating all devices). If so, it continues to parse the command. Otherwise, it discards the command and does not respond. The device needs to parse the command part to know what operation it is.

[0384] In some possible implementations, various operations must first execute inventory, then the first encapsulation command is inventory, and after the device responds to the inventory back to AMF, AMF sends subsequent commands to the device again.

[0385] AMF and the device maintain a "transaction connection" during the process. This interaction path is long. Inventory actually has 4 messages in RFID, which is more convenient for interaction between reader and tag.

[0386] In some other possible implementations, other operations do not need to execute inventory first, so the first encapsulated command is the control request. The request message group is sent out, and the AIOT device determines whether it is a message sent to itself, and only responds if it is. The response carries its own identification.

[0387] For example, Figure 6 As shown, the IoT device control method provided in the embodiment of the present application may include the following steps 21 to 30:

[0388] Step 21: AIOT App sends an AIOT control request message to AMF.

[0389] Step 22: AMF sends a NAS inventory request message to the reader.

[0390] Exemplarily, AMF can determine the reader according to the parameter information in the AIOT control request in step 1, and send a NAS inventory request message to the reader. Exemplarily, the NAS inventory request message can be represented by an AIOT NAS command. Optionally, AMF also determines the reader according to the reader / writer information corresponding to the AIOT device. Optionally, AMF also sends at least one of the following to the reader: AIOT command cycle / frequency, AIOT device identification information, AIOT NAS transactionID.

[0391] The AIOT NAS transaction ID is used to mark this NAS inventory request or this NAS inventory request process.

[0392] Exemplarily, the AIOT NAS command may be replaced with an AIOT NAS Inventory Request.

[0393] The reader can be RAN or UE. The following describes the message formats sent by AMF when the reader is RAN or UE.

[0394] AMF->reader RAN: It is a NGAP message (with NGAP header).

[0395]

[0396] AMF->reader UE: It is a NAS message (with NAS header)

[0397]

[0398] Step 23: The reader sends a NAS inventory request message to the AIOT device.

[0399] Optionally, the reader further sends at least one of AIOT device identification information and AIOT NAS transaction ID to the AIOT device. The AIOT device identification information indicates the AIOT device that needs to process the AIOT NAS command.

[0400] For example, the message from reader->AIOT device is encapsulated with AIOT AN header:

[0401]

[0402] Exemplarily, the AIOT NAS command may be replaced with an AIOT NAS Inventory Request.

[0403] Step 24: The reader receives the NAS inventory response message from the AIOT device.

[0404] Optionally, the reader also receives AIOT device identification information from the AIOT device.

[0405] Optionally, the AIOT device also sends an AIOT NAS transaction ID to the reader.

[0406] For example, the message format of AIOT device–>reader is as follows:

[0407]

[0408] Exemplarily, the AIOT NAS command response may be replaced with an AIOT NAS InventoryResponse.

[0409] Optionally, the reader records the AIOT device identification information of the AIOT device. If a link is established between the reader and the AIOT device, the reader records the corresponding relationship between the AIOT device identification information and the link.

[0410] Step 25: The reader sends a NAS inventory response message to AMF.

[0411] Optionally, the reader also sends at least one of the following to the AMF: AIOT command cycle / frequency, AIOT device identification information, and AIOT NAS transaction ID. The AIOT command cycle / frequency comes from the message in step 2. The AIOT device identification information comes from the message in step 4.

[0412] For example, the message format of reader–>AMF is as follows:

[0413] reader RAN->AMF: It is a NGAP message (with NGAP header).

[0414]

[0415] reader UE->AMF: is a NAS message (with NAS header)

[0416]

[0417] Step 26: AMF sends a core network control request message to the reader.

[0418] The core network control request message includes at least one of the following parameters: AIOT device identification information, AIOT NAS command, AIOT command period / frequency, and AIOT NAS transaction ID.

[0419] Optionally, when the AIOT device identification information in step 21 or 22 matches the AIOT device identification information in step 21 or 22, AMF sends a core network control request message to the reader.

[0420] For example, the message format of AMF–>reader is as follows:

[0421] AMF->reader RAN: It is a NGAP message (with NGAP header).

[0422]

[0423] AMF->reader UE: It is a NAS message (with NAS header)

[0424]

[0425] Step 27: The reader sends the AIOT NAS command to the AIOT device.

[0426] Optionally, the reader sends an AIOT NAS command to the AIOT device whose identifier matches the AIOT device identification information in step 26 .

[0427] For example, the message format of reader–>AIOT device is as follows:

[0428]

[0429] Step 28: The AIOT device sends an AIOT NAS command response to the reader.

[0430] Optionally, the AIOT device also sends AIOT device identification information to the reader.

[0431] For example, the message format of AIOT device–>reader is as follows:

[0432]

[0433] Step 29: The reader sends the AIOT NAS command response to the AMF.

[0434] Optionally, the reader also sends at least one of the following to the AMF: AIOT command cycle / frequency, AIOT device identification information, wherein the AIOT command cycle / frequency comes from the message in step 2, and the AIOT device identification information comes from the message in step 4.

[0435] For example, the message format of reader–>AMF is as follows:

[0436] reader RAN->AMF: It is a NGAP message (with NGAP header).

[0437]

[0438] reader UE->AMF: is a NAS message (with NAS header)

[0439]

[0440] Step 30: AMF sends a control AIOT response message to the AIOT App.

[0441] It should be noted that for the relevant explanations of this embodiment, reference may be made to the description of the above-mentioned embodiment 1.

[0442] Embodiment three:

[0443] There is no independent protocol stack between the AIOT device and AMF, only a protocol stack between the AIOT device and the reader (UE or RAN).

[0444] In some possible implementations, the AMF needs to instruct the reader what control command to execute. This can reuse the capability opening channel for transmission of control signaling.

[0445] In some other possible implementations, the command to the AIOT device is issued by the reader, but the part that is not desired to be visible to the reader may be encrypted.

[0446] For example, Figure 7 As shown, the IoT device control method provided in the embodiment of the present application may include the following steps 31 to 38:

[0447] Step 31: AIOT App sends an AIOT control request message to AMF.

[0448] Step 32: AMF sends a core network control request message to the reader.

[0449] Exemplarily, the core network control request message includes at least one of the following parameters: AIOT command, AIOT device identification information, AIOT command period / frequency, and AIOT transaction ID.

[0450] Exemplarily, the reader may be a RAN or a UE. The following describes the message formats sent by the AMF when the reader is a RAN or a UE by way of example.

[0451] AMF->reader RAN: It is a NGAP message (with NGAP header).

[0452]

[0453] AMF->reader UE: It is a NAS message of UE (with NAS header).

[0454]

[0455] Step 33: The reader sends an inventory request message to the AIOT device.

[0456] Exemplarily, the inventory request message may include at least one of the following: AIOT device identification information, AIOT transaction ID.

[0457] For example, reader->AIOT device:

[0458]

[0459] AIOT Inventory command is an inventory request message.

[0460] As a possible implementation manner, optionally, when the AIOT command in step 32 indicates inventory control, the reader executes step 33; otherwise, step 33 is not executed.

[0461] As another possible implementation, the reader executes step 33 without considering what type of control command is indicated by the AIOTcommand in step 32. In other words, after receiving the message in step 32, the reader executes step 33.

[0462] Step 34: The reader receives an inventory response message from the AIOT device, which includes the AIOT device identification information.

[0463]

[0464] Step 35: The reader sends an AIOT reader control request message to the AIOT device.

[0465] Exemplarily, the AIOT reader control request message includes at least one of the following: AIOT device identification information, AIOT reader command.

[0466] For example, the message format of reader->AIOT device is as follows:

[0467]

[0468] Optionally, the reader sends the AIOT reader command only to the AIOT device matching the AIOT device service identifier in the control request message in step 32 .

[0469] Step 36: The AIOT device sends an AIOT reader control response message to the reader.

[0470] For example, the message format of AIOT device–>reader is as follows:

[0471]

[0472]

[0473] When the AIOT device sends an inventory response to the reader, the AIOT reader command response part can be omitted or set to empty.

[0474] Step 37: The reader sends an AIOT control response message to AMF.

[0475] For example, the message format of reader->AMF is as follows:

[0476] RAN reader:

[0477]

[0478] UEreader:

[0479]

[0480] It should be noted that the parameters in the AIOT command response can be determined according to the corresponding parameters in the AIOT reader command, and may be the same or different.

[0481] Step 38: AMF sends an AIOT control response message to the AIOT App.

[0482] As another possible implementation, step 33 and step 34 are omitted. After step 32, the reader sends an AIOT reader control request message to the AIOT device. At this time, the reader can broadcast or send the AIOT reader control request message in a group manner. The AIOT device that receives the AIOT reader control request message can determine whether it needs to process the message based on the AIOT device identifier in the message. Exemplarily, if the AIOT device identifier matches its own identifier, the AIOT device executes step 36.

[0483] It should be noted that for the relevant explanations of this embodiment, reference may be made to the description of the above embodiment.
