[0055] To facilitate a better understanding of the embodiments of the present application, the Ambient Internet of Things (A-IoT) is described.

[0056] A-IoT devices have ultra-low complexity and ultra-low power consumption.

[0057] A-IoT, also known as ambient power-enabled Internet of Things (Ambient Power-Enabled IoT), is a type of Internet of Things (IoT) service. A-IoT devices are powered by energy harvesting. A-IoT devices lack batteries or have limited energy storage capabilities (for example, using a capacitor). Energy harvesting can be done from radio waves, light, motion, heat, or other suitable energy sources.

[0058] A-IoT devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, communication energy can come from environmental sources such as wind energy, kinetic energy, thermal energy, and radio frequency (RF) signals.

[0059] A-IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc., and can specifically include the following types of devices:

[0060] Passive Device: No independent signal generation / amplification, i.e. backscatter transmission;

[0061] Semi-passive devices also fall into the passive device category, but have energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy may include amplification of reflected signals.

[0062] Active Device: It has energy storage and independent signal generation, that is, it is an active RF component used for transmission.

[0063] To facilitate a better understanding of the embodiments of the present application, backscatter communication (BSC) is described.

[0064] Backscatter communication refers to the use of radio frequency signals from other devices or the environment to modulate the signal and transmit its own information. Backscatter technology, a passive or low-energy technology, is characterized by its ability to transmit its own signal by modifying the characteristics of the received ambient radio frequency signal, such as its phase or amplitude, achieving extremely low or zero power consumption.

[0065] For example, a backscatter transmission method based on binary on-off keying (OOK) can be as follows: Figure 2 As shown, a simple implementation method is that when the tag needs to send '1', the tag reflects the incident carrier signal, and when the tag needs to send '0', it does not reflect.

[0066] For example, backscatter communication can be as follows: Figure 3 As shown, the A-IoT device receives the wireless signal sent by the reading and writing device, modulates the wireless signal, loads the information to be sent, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication.

[0067] Backscatter communication devices (such as A-IoT) control the circuit's reflection coefficient Γ by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The signal reflection coefficient can be expressed as:

[0068]

[0069] Where Z0 is the antenna characteristic impedance and Z1 is the load impedance. Assume that the incident signal is S in (t), the output signal is Therefore, corresponding amplitude modulation, frequency modulation or phase modulation can be achieved by reasonably controlling the reflection coefficient.

[0070] Backscatter communication devices (such as A-IoT devices) typically use low-power reception, typically using low-power RF, IF, or baseband envelope detection. The waveform of the transmitted signal typically uses simple modulation methods such as on-off keying (OOK), amplitude shift keying (ASK), and frequency shift keying (FSK).

[0071] The device that communicates with such low-power devices (such as A-IoT devices) is called a read-write device or a first network element. For example, it can be a terminal or a relay device or a repeater, or a base station or TRP, or a device with read-write functions, such as a reader / writer. The specific details are not limited here.

[0072] To facilitate a better understanding of the embodiments of the present application, the A-IoT data / service types are explained.

[0073] Device-originating (DO) and device-terminating (DT) data indicate that the data flow originates from or is transmitted to an A-IoT device (similar to an RFID tag). Data flows originating from A-IoT devices, or DO data, can be further categorized as device-originating-autonomous (DO-A) and device-originating–device-terminated triggered (DO-DTT).

[0074] DO-A, which means devices autonomously initiate data transmission, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary.

[0075] DO-DTT refers to devices initiating data transmission after being triggered by the network. For example, asset identification, status reporting, and tracking are all downlink-triggered reports. Readers collect data from tags by triggering inventory processes. Because the data is generated / initiated in IoT devices, this service should be considered a DO service initiated by a tag, triggered by a command sent by the reader.

[0076] To facilitate a better understanding of the embodiments of the present application, the information transmission between the reader and the tag in the RFID is described.

[0077] RFID is a traditional backscatter communication system whose primary design goal is to identify and read data from BSC devices (i.e., tags) within the reader's coverage area. Because RFID was initially used for automated inventory counting of large quantities of goods, the process of identifying and reading tags is also known as inventorying. Specifically, after the reader sends a query command (Query), the tag responds (Reply). For example, if the Reply is RN16, the tag generates a 16-bit random number and sends it to the reader. The reader then sends this sequence to the tag via an ACK command. After the tag successfully verifies the RN16 in the ACK, it sends subsequent data (such as PC / XPC, electronic product code (EPC), etc.) to the reader.

[0078] like Figure 4 As shown, the command (Command) of the reader (Reader) operation can be shown in the following Table 1, and the status of the tag (Tag) can be shown in the following Table 2.

[0079] Table 1

[0080]

[0081]

[0082] Table 2

[0083]

[0084] To facilitate a better understanding of the embodiments of the present application, the RFID inventory process and anti-collision are explained.

[0085] Specifically, the RFID inventory process and anti-collision process may include the following steps 1 to 4.

[0086] Step 1: The reader is first powered on and reset, and sends a Select command to indicate that the corresponding matching conditions select this tag; the tag immediately switches to the Ready state.

[0087] Step 2: The reader sends a query command, and the tag determines whether to respond based on the inventory mark and the select mark.

[0088] The Query command starts an inventory cycle. The Query command contains the Q value. The tag (Tag) is in (0,2Q -1) generates a random number as the initial value of the slot counter.

[0089] If the matching condition is met and the slot timer value is not 0, the arbitration state is immediately entered.

[0090] Then send a query response (Query_Rep) command to reduce the slot counter value by 1;

[0091] The QueryAdjust command can change the Q value and let the tag generate a new random number (0,2 Q -1) as the value of the slot counter.

[0092] If the matching condition is met and the slot counter is 0, the RN16 is responded and the state is immediately switched to the Reply state.

[0093] Step 3: The reader sends an ACK (RN16) command. The tag responds with the PC, ECP, and CRC-16 parameters and enters the Acknowledged state.

[0094] If the reader receives responses from multiple tags at the same time, it may not be able to process multiple tags' responses at once, thus assuming a collision has occurred. The reader may not send an ACK. If a tag does not receive an ACK, the counters of these tags will be randomly incremented by 0 or 1.

[0095] Step 4: In the Acknowledged state, after receiving the REQ_RN (RN16) command, the tag responds with RN16 and switches to the Open or Secured state. The reader can then perform read and write operations on the tag.

[0096] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0097] According to RFID anti-collision methods, A-IoT devices randomly respond to readers, which can be considered a random inventory. When deploying a large number of A-IoT devices, if the random number Q value is too small, the probability of collision increases. If the random number Q value is too large, the A-IoT devices may respond intermittently, meaning that some readers' queries will not be responded to, which will prolong the entire inventory process and reduce inventory efficiency.

[0098] Based on the above technical problems, this application designs an orderly inventory solution. For statically deployed or already inventoried A-IoT devices, a suitable anti-collision method can be designed based on known information such as configuration information or inventory history information, thereby making the inventory orderly and improving inventory efficiency compared to random inventory.

[0099] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0100] Figure 5 is a schematic flow chart of an inventory method 200 according to an embodiment of the present application, as shown in FIG. Figure 5 As shown, the inventory method 200 may include at least part of the following contents:

[0101] S210, the first device sends an inventory request to the A-IoT device;

[0102] S220, the A-IoT device receives the inventory request from the first device;

[0103] S230, the A-IoT device determines a target timing based on first information; wherein the first information includes at least one of the following: a first identifier, inventory order information, a valid time of the first identifier, a valid area of ​​the first identifier, a valid time of the inventory order information, and a valid area of ​​the inventory order information; wherein the first identifier is used to identify the A-IoT device, or the first identifier is used to identify the A-IoT device within the valid area of ​​the first identifier;

[0104] S240: The A-IoT device sends an inventory response to the first device according to the target timing;

[0105] S250: The first device receives an inventory response sent based on the target timing from the A-IoT device.

[0106] It should be understood that Figure 5 The steps or operations of the inventory method 200 are shown, but these steps or operations are only examples, and the present application may also perform other operations or Figure 5 Variations of the various operations in .

[0107] In an embodiment of the present application, for A-IoT devices that are statically deployed or have been inventoried, a suitable anti-collision method can be designed based on known information such as the first identification or inventory order information, so as to make the inventory orderly and improve the inventory efficiency compared to random inventory.

[0108] The collision described in the embodiment of the present application may also be referred to as a conflict, and the collision avoidance method (collision avoidance) may also be understood as a collision resolution method (collision resolution).

[0109] The timing described in the embodiments of the present application can be a point in time, which can be represented by a frame, a subframe, a time slot, a slot, a sequence, an opportunity, etc. For example, the timing of responding to the inventory request is represented by a frame, that is, the sequence number of the timing is the number of the frame. For another example, the timing of responding to the inventory request is represented by a subframe, that is, the sequence number of the timing is the number of the subframe. For another example, the timing of responding to the inventory request is represented by a time slot, that is, the sequence number of the timing is the number of the time slot. For another example, the timing of responding to the inventory request is represented by a slot, that is, the sequence number of the timing is the number of the slot. For another example, the timing of responding to the inventory request is represented by a sequence, that is, the sequence number of the timing is the number of the sequence. For another example, the timing of responding to the inventory request is represented by an opportunity, that is, the sequence number of the opportunity is the number of the opportunity.

[0110] Exemplarily, in the above S230 , the A-IoT device determines the target timing according to the first information. Alternatively, the A-IoT device determines the order or sequence of its participation in the inventory response according to the first information.

[0111] In an embodiment of the present application, if the first device receives inventory responses from at least two A-IoT devices at the same time, the first device may not support processing the inventory responses of at least two A-IoT devices at one time, that is, it is considered that a collision has occurred.

[0112] In some embodiments, an A-IoT device may also be an A-IoT terminal, a Passive-IoT device, an Ambient Energy (AMP) device, a zero-power device, a zero-power terminal, a low-power IoT device, an IoT device, a transponder, a tag, a Radio Frequency Identification (RFID) tag, etc. Such devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the energy for communication can come from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency (RF) signals, etc.

[0113] In some embodiments, the first device includes but is not limited to at least one of the following: a reader or a read-write device, a terminal, a relay device, an auxiliary node, a repeater, an access network device (such as a base station or TRP), and a core network device.

[0114] In one embodiment, the first identifier is used to identify the A-IoT device, which can be understood as the first identifier including the identifier of the A-IoT device.

[0115] In one embodiment, the first identifier is used to identify the A-IoT device within the valid area of ​​the first identifier. It can be understood that after the A-IoT device leaves the valid area, the first identifier is not necessarily no longer the identifier of the A-IoT device.

[0116] In one embodiment, the first information includes the identification of one or more A-IoT devices or inventory order information of one or more A-IoT devices, and the identification of the one or more A-IoT devices includes the first identification.

[0117] In some embodiments, the first identifier is a permanent identifier of the A-IoT device, such as an A-IoT device identifier; or, the first identifier is a temporary identifier of the A-IoT device, such as a 5G mobile user temporary service identifier (5G-Serving-Temporary Mobile Subscriber Identity, 5G-S-TMSI) or a cell radio network temporary identifier (CellRadio Network Temporary Identity, C-RNTI), or other forms of temporary identifiers (Identity, ID).

[0118] In some embodiments, the A-IoT device reports an identifier of the A-IoT device in the inventory response, and the identifier of the A-IoT device may be the same as or different from the first identifier.

[0119] In some embodiments, the valid area of ​​the first identifier is one of the following: coverage of the first device, coverage of at least two first devices, a radio access notification area (RAN notification area, RNA), a tracking area (TA), a public land mobile network (Public Land Mobile Network, PLMN);

[0120] The at least two first devices include the first device.

[0121] In some embodiments, the valid area of ​​the inventory order information is one of the following: coverage of the first device, coverage of at least two first devices, RNA, TA, a PLMN;

[0122] The at least two first devices include the first device.

[0123] In an embodiment of the present application, the inventory order information can be used to determine the order or timing of A-IoT devices participating in the inventory.

[0124] In some embodiments, the inventory order information includes, but is not limited to, at least one of the following: the order in which the A-IoT devices historically participated in the inventory, the order or timing in which at least one A-IoT device configured by the first device participated in the inventory;

[0125] The at least one A-IoT device includes the A-IoT device.

[0126] Exemplarily, the at least one A-IoT device may be some or all of the A-IoT devices within the coverage range of the first device.

[0127] For example, an A-IoT device records its historical inventory order, such as the order in which it responded to the last inventory. For example, if N A-IoT devices successfully participated in the inventory, the A-IoT device's inventory order would be the Mth, with 1 <= M <= N. In this way, the N A-IoT devices are arranged in an orderly fashion. In the next orderly inventory round, the A-IoT devices participate in the inventory in the same order as in the previous inventory.

[0128] For another example, the first device configures an inventory order to the A-IoT device, and the A-IoT device saves the inventory order for use in subsequent inventories.

[0129] In an embodiment of the present application, for non-mobile A-IoT devices, the first device can sequentially configure first information for at least two A-IoT devices, and these A-IoT devices participate in the inventory process in sequence according to the first information, thereby reducing collisions.

[0130] In some embodiments, the first device receives part or all of the first information from a base station or a core network device. For example, the first device is a terminal or a relay device, and the first device receives part or all of the first information from a base station or a core network device. For another example, the first device is an access network device (such as a base station or a TRP), and the first device receives part or all of the first information from other access network devices or core network devices. For another example, the first device is a core network device, and the first device receives part or all of the first information from an access network device or other core network device.

[0131] In some embodiments, the first identification or inventory order information of the A-IoT device corresponds to an identification of the A-IoT device, such as a permanent identification.

[0132] In some embodiments, the first information is configured (including provided, modified, or released) by the first device through the inventory request or inventory command.

[0133] In some embodiments, the first information is configured (including providing, modifying, or releasing) by the first device after the A-IoT device completes the inventory. For example, during the inventory process, after the A-IoT device reports the identifier of the A-IoT device to the first device, the first device configures the first information (including providing, modifying, or releasing) for the A-IoT device based on the identifier of the A-IoT device reported by the A-IoT device. The first identifier included in the first information may be a temporary identifier, which is different from the permanent identifier of the A-IoT device.

[0134] In some embodiments, the first information is configured (including provision, modification, or release) by the first device after the A-IoT device is first connected; or, the first information is configured (including provision, modification, or release) by the first device after the A-IoT device completes authentication or security activation. Optionally, the authentication described in this embodiment includes authentication of the A-IoT device by the first device, or authentication of the first device by the A-IoT device.

[0135] In the embodiment of the present application, by configuring the first information, including modification and release, the first information is effectively managed, thereby supporting sequential inventory and improving inventory efficiency.

[0136] In some embodiments, the above S230 may specifically include:

[0137] The A-IoT device determines the target opportunity according to the first identifier and the number of available opportunities; or

[0138] The A-IoT device determines the order in which the A-IoT devices participate in the inventory according to the inventory order information, and the A-IoT device determines the target timing according to the order in which the A-IoT devices participate in the inventory.

[0139] Exemplarily, the timing corresponding to the order in which the A-IoT devices participate in the inventory can be the target timing, or the serial number of the A-IoT devices participating in the inventory can be the serial number of the target timing. For example, the timing of responding to the inventory request is represented by the order. In this case, the order in which the A-IoT devices participate in the inventory is the target timing, or the serial number of the order in which the A-IoT devices participate in the inventory is the serial number of the target timing. For another example, the timing of responding to the inventory request is represented by the time slot. In this case, the time slot corresponding to the order in which the A-IoT devices participate in the inventory (such as the time slot occupied by the inventory response sent during the A-IoT device's participation in the inventory) is the target timing, or the time slot number corresponding to the order in which the A-IoT devices participate in the inventory is the serial number of the target timing. For another example, the timing of responding to the inventory request is represented by a subframe. In this case, the subframe corresponding to the order in which the A-IoT devices participate in the inventory (such as the subframe occupied by the inventory response sent during the A-IoT device's participation in the inventory) is the target timing, or the subframe number corresponding to the order in which the A-IoT devices participate in the inventory is the sequence number of the target timing.

[0140] Optionally, the resources used by the inventory responses sent by A-IoT devices during the inventory process can be configured using inventory commands. For example, inventory command 1 carries the resources used by the A-IoT device during the inventory process corresponding to inventory command 1, inventory command 2 carries the resources used by the A-IoT device during the inventory process corresponding to inventory command 2, and so on. Inventory command m carries the resources used by the A-IoT device during the inventory process corresponding to inventory command m.

[0141] In some embodiments, the A-IoT device determines the sequence number of the target opportunity according to the following formula:

[0142] Ts = ID1 mod N;

[0143] Ts represents the sequence number of the target opportunity, ID1 represents part or all of the bits of the first identifier, and N represents the number of available opportunities (Number of Occasions).

[0144] In an embodiment of the present application, when configuring the first identifier, the first device needs to consider the number of available opportunities and the number of A-IoT devices to avoid the same or conflicting sequence numbers of target opportunities determined by different A-IoT devices based on the above formula. For example, the first device can sequentially and continuously configure the first identifier for at least two A-IoT devices, and during the configuration, it is necessary to avoid the same or conflicting sequence numbers of target opportunities determined by different A-IoT devices based on the above formula.

[0145] In the embodiment of the present application, the Ts determined by different A-IoT devices based on the above formula are ordered and continuous, so that the A-IoT devices can participate in the inventory in an orderly manner based on the sequence number of the target opportunity.

[0146] For example, the value of N can be associated with the random number Q, or the value of N can be determined based on the random number Q. For example, N=2 Q .

[0147] In this embodiment, the target timing for each A-IoT device to respond to an inventory request can be determined, so that the target timing is allocated in order according to the first identifier, which can reduce the collision of multiple A-IoT devices sending response messages at the same time.

[0148] In some embodiments, the above S240 may specifically include:

[0149] The A-IoT device receives the inventory command, and when the timing information included in the inventory command matches the target timing, the A-IoT device sends the inventory response to the first device.

[0150] Alternatively, the first device may broadcast an inventory command.

[0151] In this embodiment, the inventory command includes an inventory sequence number or timing information corresponding to the current inventory command. When the timing information indicated by the inventory command matches the target timing, the A-IoT device responds to the first device.

[0152] In this embodiment, the inventory sequence number or timing information included in the inventory command can remain unchanged to complete the inventory of one A-IoT device. After the first device completes the inventory of one A-IoT device (successfully or unsuccessfully), it changes the inventory sequence number or timing information included in the second inventory command and continues to inventory other A-IoT devices.

[0153] In some embodiments, the above S240 may specifically include:

[0154] The A-IoT device receives the inventory command and counts the received inventory commands through a counter. When the count value of the counter matches the target timing, the A-IoT device sends the inventory response to the first device.

[0155] In this embodiment, the A-IoT device sets a counter. Inventory commands do not include an inventory sequence number or timing information, for example, if the inventory command is a query or a repeated query. The A-IoT device counts received inventory commands, incrementing or decrementing the counter by 1 each time it receives an inventory command. When the counter reaches 0 or when the counter equals the sequence number corresponding to the target timing, the A-IoT device responds to the first device.

[0156] It should be noted that the inventory command can be sent multiple times to trigger the A-IoT device to respond. In the embodiment of the present application, the inventory request and the inventory command can be different.

[0157] In some embodiments, the inventory request includes but is not limited to at least one of the following:

[0158] Information on conditions for participating in inventory counting, inventory counting mode information, and timing-related configuration information;

[0159] The condition information for participating in the inventory is used to determine the A-IoT devices participating in the inventory, and the inventory mode information is used to indicate the inventory mode used in the inventory process.

[0160] Optionally, the condition information for participating in the inventory includes but is not limited to at least one of the following: having the first identifier, having some or all bits of the first identifier, and having an inventory order.

[0161] For example, the condition information for participating in the inventory includes having the first identifier. In this case, the A-IoT device having the first identifier participates in the inventory.

[0162] For another example, the condition information for participating in the inventory includes some or all bits of the first identifier. In this case, A-IoT devices that have some or all bits of the first identifier participate in the inventory.

[0163] For another example, the condition information for participating in the inventory includes having an inventory order. In this case, the A-IoT devices that have the inventory order participate in the inventory.

[0164] Optionally, the inventory mode includes but is not limited to at least one of the following: a first inventory mode and a second inventory mode, wherein the first inventory mode is a sequential inventory or an inventory based on the first information, and the second inventory mode is a random inventory or an initial inventory.

[0165] Exemplarily, the first inventory mode may also be an inventory of A-IoT devices that have been inventoried before, or an inventory of A-IoT devices with the first identifier.

[0166] It should be understood that the first inventory mode can be understood as an inventory based on historical and known information to improve inventory efficiency. For example, the first identifier is the information that the first device configured for the A-IoT device during a previous inventory process, which can be understood as historical information. In the first inventory mode, the inventory of A-IoT devices with the first identifier is performed in sequence, which is also an inventory based on historical information.

[0167] It should be understood that the second inventory mode can be understood as a random inventory or an initial inventory, and an inventory is performed on A-IoT devices that participate in the inventory for the first time, or an inventory is performed on A-IoT devices that do not have the first information such as the first identifier.

[0168] Optionally, the timing-related configuration information includes but is not limited to at least one of the following: the number of available timings (NumberOfOccasion), and the inventory order information.

[0169] For example, the number of available opportunities can also be indicated by the Q value, so the number of opportunities is 2 Q For example, the timing number is in the range (0,2 Q -1).

[0170] Exemplarily, the inventory order information is used to indicate the order or timing of the A-IoT devices participating in the inventory. Optionally, the configured timing can be multiple timings, or multiple occurrences or periodic occurrences.

[0171] For example, the first device may configure a corresponding inventory order for each A-IoT device within its coverage area, and each A-IoT device may participate in the inventory as needed.

[0172] In some embodiments, the above S230 may specifically include:

[0173] The A-IoT device determines whether a first condition is satisfied according to at least one of the following, and when the first condition is satisfied, the A-IoT device determines the target timing according to the first information:

[0174] the first identifier;

[0175] The inventory order information;

[0176] Information on the conditions for participating in the inventory;

[0177] The inventory mode used by the A-IoT device during the inventory process;

[0178] Configuration information related to the timing.

[0179] In some embodiments, satisfying the first condition includes at least one of the following:

[0180] The A-IoT device is configured with the first identifier;

[0181] The A-IoT device is configured with the inventory order information;

[0182] The A-IoT device meets the conditions for participating in the inventory;

[0183] The inventory mode used by the A-IoT device during the inventory process is the first inventory mode;

[0184] The A-IoT device is configured with the timing-related configuration information.

[0185] In some embodiments, the inventory mode used by the A-IoT device during the inventory process is configured by the first device through the inventory request, or the inventory mode used by the A-IoT device during the inventory process is configured by the first device through whether the inventory command carries the inventory order or timing.

[0186] For example, one bit in the inventory request is used to indicate the inventory mode used by the A-IoT device during the inventory process; wherein, a value of 0 indicates that the inventory mode used by the A-IoT device during the inventory process is the first inventory mode, and a value of 1 indicates that the inventory mode used by the A-IoT device during the inventory process is the second inventory mode; or, a value of 1 indicates that the inventory mode used by the A-IoT device during the inventory process is the first inventory mode, and a value of 0 indicates that the inventory mode used by the A-IoT device during the inventory process is the second inventory mode.

[0187] For another example, the inventory command carries the inventory order or timing to indicate that the inventory mode used by the A-IoT device during the inventory process is the first inventory mode, while the inventory command does not carry the inventory order or timing to indicate that the inventory mode used by the A-IoT device during the inventory process is the second inventory mode.

[0188] In some embodiments, the A-IoT device releases the first information when at least one of the following conditions is met:

[0189] The validity period of the first identifier expires;

[0190] The validity period of the inventory order information has expired;

[0191] The A-IoT device is located outside the valid area of ​​the first information;

[0192] The inventory counting device is located outside the effective area of ​​the inventory counting sequence information;

[0193] Other first devices except the first device configure new first information for the A-IoT device (that is, the old first information is invalid);

[0194] The A-IoT device is inventoried by other first devices other than the first device;

[0195] The A-IoT device is inventoried by other first devices outside the valid area of ​​the first information;

[0196] The A-IoT device is not inventoried or the inventory fails in the inventory of the first inventory mode.

[0197] Optionally, the validity period or validity area of ​​the first information may also be agreed upon by a protocol.

[0198] In some embodiments, after the A-IoT device releases the first information, the A-IoT device participates in subsequent inventory checks using the second inventory check mode; or

[0199] After the A-IoT device is not counted or fails in the inventory in the first inventory mode, the A-IoT device participates in a subsequent inventory using the second inventory mode.

[0200] Exemplarily, after the A-IoT device releases the first information, it participates in subsequent inventories using the second inventory mode. It is understood that after the A-IoT device releases the first information, it cannot participate in the first inventory mode, but can participate in the second inventory mode. For example, after not being inventoried or failing in the first inventory mode, the A-IoT device may participate in a subsequent inventory in the second inventory mode.

[0201] In some embodiments, before the A-IoT device determines the target timing according to the first information, the wireless communication method 200 further includes:

[0202] The A-IoT device sends capability information to the first device;

[0203] The capability information includes but is not limited to at least one of the following:

[0204] The A-IoT device supports configuration or use of the first identifier or the inventory order information;

[0205] The A-IoT device supports determining the target timing based on the first information;

[0206] The A-IoT device supports the first inventory mode.

[0207] Specifically, after receiving the capability information, the first device configures the first information to the A-IoT device, or sends the inventory request to initiate inventory in the first inventory mode.

[0208] This embodiment facilitates the first device to initiate inventory when the A-IoT device has the capability of the first inventory mode, thereby avoiding inconsistent understanding between the A-IoT device and the first device, thereby avoiding disordered configuration of the first information and ensuring subsequent inventory efficiency.

[0209] In some embodiments, the wireless communication method 200 further includes at least one of the following:

[0210] The first device preferentially performs an inventory of the A-IoT device having the first information among the at least two A-IoT devices based on the first inventory mode;

[0211] The first device performs an inventory on an A-IoT device that does not have the first information among the at least two A-IoT devices based on the second inventory mode.

[0212] For example, if there are A-IoT devices with the first information, the first device first performs an inventory on the A-IoT devices with the first information based on the first inventory mode. Then, if there are other A-IoT devices, the first device performs an inventory on the A-IoT devices that do not have the first information based on the second inventory mode.

[0213] In this embodiment, multiple inventory counting modes are adopted, such as a combination of initial inventory counting (second inventory counting mode) and efficient inventory counting (first inventory counting mode), to reduce the probability of collision and improve inventory counting efficiency.

[0214] In some embodiments, the wireless communication method 200 further includes: the first device configuring the first information for the A-IoT device among the at least two A-IoT devices that has been successfully inventoried using the second inventory mode. This facilitates sequential inventorying of A-IoT devices using the first inventory mode in the future.

[0215] In some embodiments, after an A-IoT device equipped with first information receives a first inventory request of a first inventory mode, the A-IoT device determines a target timing to participate in the inventory according to the first information. If the A-IoT device fails to successfully complete the inventory triggered by the first inventory request, the A-IoT device participates in the inventory of the second inventory mode. For example, the A-IoT device deletes or releases the first information. In this case, the A-IoT device does not respond to the first inventory request or the specific inventory command of the first inventory mode, but participates in the inventory of the second inventory mode; wherein the specific inventory command may be an inventory command that does not carry inventory order or timing information.

[0216] Therefore, in an embodiment of the present application, the A-IoT device can determine the target timing based on the first identifier or inventory order information, and the A-IoT device sends an inventory response to the first device based on the target timing. When determining the timing of responding to the inventory request, the first identifier or inventory order information is referenced, so that the timing of responding to the inventory request can be arranged in an orderly manner, thereby achieving orderly inventory, improving inventory efficiency, and reducing collisions between different A-IoT devices when responding to inventory requests.

[0217] The technical solution of this application is described below through Example 1 and Example 2.

[0240] S2-1. The A-IoT device receives an inventory request sent by the first device, wherein the inventory request includes at least one of the following: condition information for participating in the inventory, inventory mode information, and timing-related configuration information.
