[0044] Ambient Internet of Things (A-IoT), also known as ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an Internet of Things (IoT) service in which IoT devices are powered by energy harvesting. IoT devices do not have batteries or have limited energy storage capabilities (for example, using a capacitor). Energy sources for energy harvesting include radio waves, light, motion, heat, or other suitable energy sources.

[0045] The energy of Ambient IoT devices comes from energy harvesting. Regarding energy storage, Ambient IoT devices can have the following features:

[0046] - No battery, no energy storage. That is, Ambient IoT devices are completely dependent on external energy sources. Or,

[0047] - Limited energy storage capacity; no battery replacement or charging required.

[0048] Typically, Ambient IoT devices do not have traditional batteries. Instead, the Ambient IoT devices themselves use energy harvested from radio waves, which can come from network equipment or user equipment, such as mobile phones.

[0049] Ambient IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc.

[0050] Among them, the passive or active transmission of ambient IoT devices has the following communication modes:

[0051] -Normal operation. In this case, the Ambient IoT device has power to operate continuously or for a period of time. The energy can come from continuous energy harvesting, or it may have a certain energy storage capability, such as being equipped with a capacitor.

[0052] - Active transmission, supporting device-triggered operations. Among them, the device can only support short-term active state and intermittent communication. Ambient IoT devices can decide when to communicate with the network. Ambient IoT devices do not necessarily monitor the network, that is, they may not monitor the called business for a long time.

[0053] - Passive transmission, only supports on-demand operations initiated by the network. Among them, Ambient IoT devices cannot initiate services by themselves.

[0054] Backscatter communication refers to the use of radio frequency signals from other devices or the environment by backscatter communication devices to modulate signals and transmit their own information. Backscatter communication terminal equipment (BSC Tag, also known as BSC UE) can be a tag in traditional RFID, or an ambient energy storage IoT (Ambient IoT), or a passive IoT (Passive-IoT) device.

[0055] Backscatter technology is a passive or low-energy technology. Its technical feature is that it can complete the transmission of its own signal by changing the characteristics of the received ambient RF signal, such as phase or amplitude information, to achieve extremely low power or zero power information transmission.

[0056] From the perspective of power supply, backscatter communication terminal equipment (BSC Tag) can be divided into three types: fully passive (Passive), semi-passive (Semi-passive) and active (active).

[0057] -For passive backscatter communication, BSC TAG first obtains energy from external electromagnetic waves (Energy harvesting) and supplies it to internal channel coding and modulation circuit modules, while communicating by reflecting and scattering RF signals, thereby achieving zero-power communication.

[0058] -For the semi-passive BSC TAG, its internal circuit module is powered by its own battery and communicates by backscattering RF signals. Since its internal battery is only used for simple channel coding and modulation and other internal circuit module operations, the power consumption is very low, so the battery life of the BSC TAG can reach more than ten years. All external RF signals can be used for reverse communication without storing part of the energy for power supply.

[0059] -For active BSC TAG, its built-in battery is not only used for simple internal circuit operations such as channel coding and modulation, but also for circuit operations such as power amplifier (PA) and low noise amplifier (LNA), thus realizing more complex signal modulation and demodulation of backscatter communication.

[0060] As a terminal device, if the A-IoT device needs to transmit data with the network side device, before the data transmission, the A-IoT device needs to report auxiliary information for assisting the data transmission to the network side device. Specifically, the A-IoT device reports the auxiliary information to the reader, and the reader sends the auxiliary information to the core network device. However, the actual business data block of the A-IoT device is small, so the air interface resources occupied by these auxiliary information are more than the air interface resources occupied by the transmission of business data. In addition, the transmission of auxiliary information will also increase the complexity of the high-level protocol stack of the A-IoT device. In view of this problem, the embodiment of the present application provides a reading and writing scheme for an environmental Internet of Things device. In the reading and writing scheme provided by the embodiment of the present application, the reader obtains operation configuration information from the core network device, and based on the operation configuration information, performs a read operation or a write operation on the target environmental Internet of Things device to realize data transmission between the environmental Internet of Things device and the environmental Internet of Things device. The environmental Internet of Things device does not need to report the auxiliary information of the data transmission, thereby saving the air interface resources occupied by the A-IoT device to report the auxiliary information to the reader, and reducing the complexity of the high-level protocol stack of the A-IoT device.

[0061] The following, in conjunction with the accompanying drawings, describes in detail the reading and writing solutions of the environmental Internet of Things devices provided by the embodiments of the present application through some embodiments and their application scenarios.

[0062] Figure 2 A flowchart of a method for reading and writing an environmental Internet of Things device in an embodiment of the present application is shown, and the method 200 can be executed by a reader / writer. In other words, the method can be executed by software or hardware installed on the reader / writer.

[0063] In the embodiments of the present application, Figure 3a As shown in Figure 1, the reader can be deployed as a functional module of the base station, and the base station can directly communicate with the A-IoT device. Figure 3b As shown, the reader can be integrated into the base station as a functional unit, and the base station communicates with the A-IoT device through an auxiliary node such as a Network Controlled Repeater (NCR) node or a Reconfigurable Intelligent Surface (RIS) node. Figure 3cAs shown, the reader is a unit deployed separately from the base station. The AmbientIoT setting involved can be a terminal device based on passive communication or a fixedly deployed reader / writer device controlled by the base station. The reader / writer device communicates with the A-IoT device under the control of the base station. The communication between the reader and the A-IoT device can be based on the backscatter communication mechanism or the active communication method in which the ambient IoT device generates and transmits radio waves by itself.

[0064] like Figure 2 As shown, the reading and writing method of the environmental Internet of Things device mainly includes the following steps.

[0065] S210, the reader / writer obtains operation configuration information from the core network device.

[0066] In an embodiment of the present application, the operation configuration information is used to indicate a target operation to be performed on an IoT device in a target environment, wherein the target operation includes one of the following: a read operation and a write operation.

[0067] In the embodiment of the present application, the reader / writer obtains the operation configuration information from the core network device. Figure 3a and Figure 3b In the core network, the reader can directly receive the operation configuration information sent by the core network device, and Figure 3c In the process, the reader / writer can obtain the above operation configuration information from the core network device through the base station. For example, the core network device can send the above operation configuration information to the reader / writer through the base station.

[0068] In the embodiment of the present application, the core network device can send the above-mentioned operation configuration information to the reader / writer based on the request of the environmental Internet of Things application server. For example, if the environmental Internet of Things application server needs to obtain a certain target information on a certain environmental Internet of Things device, the environmental Internet of Things application server can send a read request and operation auxiliary information to the core network device, and the operation auxiliary information can include at least one of the identification information of the environmental Internet of Things device, the identification information of the target information to be obtained, and the storage address of the target information. After receiving the read request and the operation auxiliary information, the core network device generates the above-mentioned operation configuration information based on the read request and the operation auxiliary information and sends it to the reader / writer.

[0069] Optionally, the operation configuration information may include at least one of the following:

[0070] (1) First identification information, the first identification information is used to identify one of the following: the target environment IoT device, the target environment IoT device set; the target environment IoT device set includes at least one of the target environment IoT devices; for example, the first identification information may include the identification of at least one environment IoT device, which is used to indicate the environment IoT device corresponding to the target operation. Alternatively, the first identification information may also include the identification of at least one environment IoT device set, which is used to indicate that the environment IoT device corresponding to the target operation is each environment IoT device in the at least one environment IoT device set.

[0071] (2) second identification information, the second identification information is used to identify the target information operated by the target operation; for example, the second identification information may be a service identifier corresponding to the target information to be read or written. For another example, the second identification information may also be a name for storing the target information in the target IoT device.

[0072] (3) Address information, where the address information is used to indicate the storage address of the target information on the target environment IoT device; the address information can determine the location where the target information corresponding to the target operation is stored in the target environment IoT device.

[0073] (4) First indication information, where the first indication information is used to indicate the size of the target information; the first indication information can be used to indicate the size of the target information to be read or written.

[0074] (5) Second indication information, the second indication information is used to indicate one of the following: encrypting the data transmitted between the target environment IoT device and the reader / writer, or not encrypting the data transmitted between the target environment IoT device and the reader / writer. Through the second indication information, it can be known whether it is necessary to encrypt the data transmitted between the reader / writer and the target environment IoT device, that is, whether to perform encrypted transmission between the reader / writer and the target environment IoT device. The reader / writer can perform corresponding operations based on the second indication information. For example, if the second indication information indicates that encrypted transmission is required, the reader / writer transmits data after completing the air interface encryption parameter interaction with the target A-IoT device. If the second indication information indicates that encrypted transmission is not required, the reader / writer does not need to complete the air interface encryption parameter interaction with the target A-IoT device to transmit data. In addition, if the application layer of the target A-IoT device has encrypted the data, the air interface does not need to encrypt the read data.

[0075] S212, the reader / writer performs the target operation on the target environment IoT device based on the operation configuration information.

[0076] The reader / writer performs corresponding operations on the target environment IoT device based on the operation configuration information. For example, if the operation configuration information is used to perform a read operation on the target environment IoT device, the reader / writer performs a read operation to read the target information stored in the target environment IoT device; if the operation configuration information is used to perform a write operation on the target environment IoT device, the reader / writer performs a write operation to write the target information into the target environment IoT device.

[0077] Through the technical solution provided in the embodiments of the present application, the reader / writer performs target operations on the IoT devices in the target environment based on the operation configuration information from the core network. There is no need for the A-IoT device to report auxiliary information of uplink data reading, such as SR / BSR. The application layer on the A-IoT device can be omitted or the application layer on the A-IoT device can be greatly simplified. The reader / writer can directly read and write specific memory areas on the A-IoT device, thereby saving air interface resources and reducing the complexity of the high-level protocol stack of the A-IoT device.

[0078] In an optional implementation, before S212, the method may further include the following steps:

[0079] Step 1: The reader / writer reads the third identification information of the candidate environment Internet of Things device from the candidate environment Internet of Things device.

[0080] In this implementation, after obtaining the above operation configuration information, the reader can read the third identification information of each candidate environment IoT device within its communication range to determine the target environment IoT device. Figure 3a In the case of a base station, the reader can read the third-party identification information of the IoT devices in the environment within the coverage area of ​​the base station, and in Figure 3b In the case of , the reader can obtain the third identification information of the candidate environment IoT device through the auxiliary node within the coverage range of the base station, while in Figure 3c In the process, the reader can obtain the third identification information of the candidate environment IoT devices within its communication range.

[0081] Step 2: When the read third identification information matches the first identification information, the reader / writer determines that the candidate environment IoT device is the target environment IoT device.

[0082] After acquiring the third identification information of the candidate environment IoT device, the reader / writer can determine whether the third identification information matches the first identification information. For example, if the first identification information includes identification information of at least one target environment IoT device, then determine whether the third identification information is one of the at least one identification information included in the first identification information; if the first identification information includes identification information of at least one target environment IoT device set, then determine whether the third identification information belongs to the identification information of a target environment IoT device in the target environment IoT device set indicated by the first identification information, and take the candidate environment IoT device whose third identification information matches the first identification information as the target environment IoT device.

[0083] In an optional implementation, the operation configuration information may be read configuration information, which is used to instruct a read operation on the target environment IoT device. Then in S212, the reader / writer may perform a read operation of reading the target information from the target environment IoT device based on the operation configuration information. Through this optional implementation, the reader / writer may read the target information from the target environment IoT device based on the read configuration information of the core network. Prior to this, the target environment IoT device does not need to report auxiliary information of the uplink data reading, and the application layer of the target environment IoT device may be omitted or simplified, thereby saving air interface resources and reducing the complexity of the target environment IoT device.

[0084] In the above optional implementation, the above operation configuration information may also include at least one of the following (1) to (4).

[0085] (1) Third indication information, the third indication information is used to indicate that a read operation is to be performed on the target environment IoT device. Therefore, the third indication information can also be called a single read indication, indicating the reader / writer to read the target information from the target environment IoT device once.

[0086] (2) Fourth indication information, the fourth indication information is used to indicate to perform a periodic reading operation on the target environment IoT device. Therefore, the fourth indication information can also be called periodic reading configuration information.

[0087] Optionally, the fourth indication information may include: time-related information of the first reading and reading cycle information, wherein the time-related information of the first reading includes one of the following: time offset information of the first reading and reading time of the first reading. The reader / writer may determine the time of first reading the target information from the target environment IoT device according to the time-related information of the first reading in the fourth indication information, and then read the target information for the first time at that time, and then, when the reading cycle indicated by the reading cycle information arrives, perform a second reading, and thus periodically read the target information from the target environment IoT device.

[0088] Optionally, the time offset information of the first reading may be the offset of the time of the first reading relative to the time of receiving the operation configuration information. For example, the time offset information of the first reading may indicate n time slots, and the reader performs the first reading in the nth time slot after receiving the operation configuration information.

[0089] (3) fifth indication information, wherein the fifth indication information is used to indicate to perform a semi-static read operation on the target environment IoT device.

[0090] Optionally, the fifth indication information may include: time-related information of the first reading and reading cycle information, wherein the time-related information of the first reading includes one of the following: time offset information of the first reading and reading time of the first reading. The reader / writer may determine the time of first reading the target information from the target environment IoT device based on the time-related information of the first reading in the fourth indication information, and then read the target information for the first time at the time, and then perform a second reading when the reading cycle indicated by the reading cycle information arrives.

[0091] In this optional implementation, when the operation configuration information includes fifth indication information indicating the execution of a semi-static read operation, the reader / writer may determine the total number of reads in accordance with the protocol agreement or default configuration, or determine the time period for executing the semi-static read operation in accordance with the protocol agreement or default configuration, or, alternatively, stop the periodic reading of the target information the next time the operation configuration information indicating the read operation is received.

[0092] Optionally, the fifth indication information may further include at least one of the following:

[0093] a) an indication for activating or reactivating the semi-static read operation; through the indication, the reader can determine to activate or reactivate the semi-static read operation, and read the target information from the target environment Internet of Things in a semi-static reading manner.

[0094] b) an instruction to stop or pause the semi-static read operation; through this instruction, the reader can be instructed to stop or pause the semi-static read operation currently being performed. For example, if the reader is currently performing a semi-static read operation on a certain information stored in the target IoT device, the fifth instruction information can instruct to stop or pause the semi-static read operation.

[0095] c) An indication of the time period for executing the semi-static read operation; through this indication, the reader can be instructed to execute the semi-static read operation on the target information for a period of time, that is, to perform periodic reading on the target information within this period, and stop reading the target information after exceeding this period.

[0096] d) The number of times the semi-static read operation is performed. This indication can indicate the number of times the reader performs the semi-static read operation on the target information, that is, the number of times the target information is read according to the read cycle indicated by the read cycle information. After the number is exceeded, the target information is stopped from being read.

[0097] (4) The transceiver capability information of the target environment IoT device. By indicating the transceiver capability information of the target environment IoT device, the reader can read data according to the transceiver capability of the target environment IoT device to avoid data reading interruption. For example, for an A-IoT device that provides power based on energy collection, the transceiver capability information may include energy collection duration parameters, continuous transceiver duration after full charge, and maximum uplink transmission power, etc. The reader can read data in a manner that matches the transceiver capability of the target A-IoT device to avoid data reading interruption.

[0098] In an optional implementation, the reader / writer may perform a read operation of reading the target information from the target environment IoT device, including the following steps:

[0099] Step 1, the reader / writer sends the first downlink control information to the target environment IoT device, wherein the first downlink control information includes at least one of the following: a read operation instruction, the second identification information, the address information, and the first instruction information;

[0100] Step 2: The reader receives the reading result returned by the target environment IoT device.

[0101] The above optional implementation method provides an optional implementation method for a reader to perform a read operation, but is not limited to this. In specific applications, the reader can also read the target information from the target environment IoT device in other ways. For example, the reader sends a query instruction for querying the target information to the target environment IoT device. After receiving the query instruction, the target environment IoT device responds to the query instruction, queries the locally stored target information, and returns it to the reader.

[0102] In the above optional implementation, the target A-IoT device directly sends the data specified by the reader to the reader, thereby eliminating the need to obtain the process of sending data from the application layer, thereby reducing the complexity of the target A-IoT device.

[0103] In order to avoid reading failure or meaningless reading, in an optional implementation, before the reader sends the first downlink control information to the target environment IoT device, the method may further include the following steps:

[0104] Step 1: The reader sends an inquiry request to the target environment IoT device, wherein the inquiry request is used to inquire at least one of the following: whether the target information is stored, and whether the target information has changed relative to the content last read;

[0105] Step 2: The reader receives feedback information returned by the target environment IoT device.

[0106] Through this optional implementation method, the reader / writer can know whether the target information is stored in the target environment IoT device or whether the target information has changed compared to the most recently read content before sending the first downlink control information. Therefore, it can determine whether to send the first downlink control information based on the feedback information returned by the target environment IoT device to avoid reading failure or invalid reading.

[0107] In the above implementation, optionally, the reader / writer sending the first downlink control information to the target environment IoT device may include: when the feedback information indicates that the target information is stored and the target information has changed relative to the content of the last read, the reader / writer sends the first downlink control information to the target environment IoT device. This optional implementation can avoid reading failures due to the target information not being stored in the target environment IoT device or invalid reading due to the target information stored in the target environment IoT device not changing relative to the last read.

[0108] In the above implementation, when the feedback information indicates that the target information is not stored or the target information has not changed compared with the content read the most recently, the reader / writer terminates the process of reading the target information.

[0109] In an optional implementation, after the reader / writer performs a read operation of reading the target information from the target environment IoT device based on the operation configuration information, the method further includes: the reader / writer sends a read result of performing the read operation to the core network device. The read result may include one of the following: the read target information, the read operation was not successfully performed, and the read operation was not performed. For example, if the reader / writer reads the target information, the reader / writer sends the read target information to the core network device. If the reader / writer fails to perform the read operation, for example, the target information is not stored in the target environment IoT device, the reader / writer sends a message to the core network device that the read operation was not successfully performed. If the reader / writer does not perform the read operation, for example, the target information stored in the target environment IoT device has not changed relative to the most recent read, the reader / writer sends a message to the core network device that the read operation was not performed.

[0110] In an optional implementation, when the read result is that the read operation was not successfully executed or the read operation was not executed, the reader / writer may also send read execution information to the core network device, wherein the read execution information is used to indicate the reason why the read operation was not successfully executed or the read operation was not executed.

[0111] Optionally, the reason why the read operation is not successfully performed or the read operation is not performed includes one of the following:

[0112] (1) The target environment IoT device is not found; for example, the identification information of all candidate environment IoT devices read does not match the first identification information.

[0113] (2) The target environment IoT device is found, but reading the target information fails; for example, the target information is not stored in the target environment IoT device.

[0114] (3) The target environment IoT device is found, but the target information has not changed since the last reading.

[0115] Through the above optional implementation method, when the target information is not read, the core network device can know the reason why the target information is not read.

[0116] In an optional implementation, the operation configuration information may be read configuration information, which is used to instruct to perform a read operation on the target environment IoT device. Then in the above S212, the reader / writer may perform a write operation to write the target information into the target environment IoT device based on the operation configuration information.

[0117] In the above optional implementation method, the reader / writer directly writes the target information to the target A-IoT device, and the target A-IoT device stores the received data stored in the specified memory area in the specified memory area, without submitting the received data to the application layer, thereby reducing the complexity of the target A-IoT device.

[0118] In the above optional implementation, the operation configuration information may also include: the capability information of the target environment IoT device for downlink reception. For example, the capability information of the target environment IoT device for downlink reception may include the duration of continuous reception of the target environment IoT device and the time parameters for energy collection of the target environment IoT device. Thus, the reader / writer can write the target information to the target environment IoT device according to the capability information of the target environment IoT device for downlink reception, thereby avoiding write failure.

[0119] In an optional implementation, the reader / writer may perform the following steps to write the target information to the target environment IoT device for reading based on the operation configuration information:

[0120] Step 1, the reader sends second downlink control information to the target environment IoT device, wherein the second downlink control information includes at least one of the following: a write operation indication, second identification information for identifying the target information for performing a write operation on the target A-IoT device, storage address information of the target information on the target A-IoT device, and the first indication information; wherein the second identification information can be used by the target A-IoT device to determine the storage file, storage space, etc. of the target information.

[0121] After receiving the second downlink control information, the target A-IoT device receives and stores the target information from the reader / writer according to the second downlink control information.

[0122] Step 2: The reader / writer obtains the operation result of the target environment IoT device performing the write operation.

[0123] For example, after successfully storing the target information locally, the target environment IoT device can return a response to the reader / writer indicating that the write operation is successfully completed, and the operation result obtained by the reader / writer is that the write operation is successfully completed. If the identification information of all candidate environment IoT devices read by the reader / writer does not match the first identification information, the operation result obtained by the reader / writer may be that the write operation is not performed. If the target environment IoT device fails to store the target information locally, for example, due to insufficient storage space, the target environment IoT device can return a response to the reader / writer indicating that the write operation failed, and the operation result obtained by the reader / writer is that the write operation was not successfully performed.

[0124] In an optional implementation, after the reader / writer obtains the operation result of the target environment IoT device executing the write operation, the method may also include: the reader / writer sends the execution information of the write operation to the core network device, wherein the execution information of the write operation includes one of the following: successful completion of the write operation, unsuccessful execution of the write operation, or the reason for not executing the write operation.

[0125] Optionally, the reason why the write operation is not successfully performed or is not performed may include one of the following: the target environment IoT device is not found; the target environment IoT device is found, but the write operation fails.

[0126] Through the above optional implementation method, the reader / writer can send the execution information of the write operation to the core network device, so that the core network device can obtain the execution information of the write operation.

[0180] Figure 6 A flowchart of a method for reading and writing an A-IoT device in an embodiment of the present application is shown. In the method 600, the reader receives read configuration information about a target A-IoT device or a target A-IoT device set from the core network, performs a read operation on the target A-IoT device or a target A-IoT device set, and sends the read operation result to the core network. Figure 6 As shown, the method mainly includes the following steps:

[0181] S601, the application server sends a read request to the core network device.

[0182] The read request may carry the read auxiliary information, or the read auxiliary information may be sent together with the read request.

This transceiver capability information enables the reader to read data according to the transceiver capability of the target A-IoT device, thus avoiding data reading interruption.

[0194] (9) Implicitly or explicitly indicate whether encrypted transmission is required over the air interface. For example, if encrypted transmission is required, the reader is instructed to transmit after completing the air interface encryption parameter interaction with the target A-IoT device. Otherwise, transmission can be performed without completing the air interface encryption parameter interaction with the target A-IoT device. If the application layer of the target A-IoT device has encrypted the data, the air interface does not need to encrypt the read data.

[0195] S603, the reader / writer reads the identification information of the A-IoT device from the A-IoT device. If the read identification information matches the identification information of the target A-IoT device received from the core network device, it is determined that the target A-IoT device is found and S604 is executed.

[0196] S604, the reader / writer performs a read operation on the target A-IoT device.

[0204] Step 3, the reader receives feedback information about 1) or 2) from the target A-IoT device; if the target information is not ready or has not changed compared to the content of the last read / write, the reader can terminate the process of reading information from the target A-IoT device; otherwise, the target information is read from the target A-IoT device;

[0205] Step 4: If the reader terminates the target information reading process, it sends an indication message to the core network indicating that the target information has not been read or has not changed.

[0209] (3) The A-IoT device is found but the target information has not changed since the last read, so no reading is required.

[0210] S605, the reader / writer sends the reading result to the core network.

[0211] S606: The core network sends the received reading result to the application server.

In the method 700, the reader receives write operation configuration information about a target A-IoT device or a target A-IoT device set from the core network, performs a write operation on the target A-IoT device or a target A-IoT device set, and sends the write operation result to the core network. Figure 7 As shown, the method mainly includes the following steps:

[0213] S701, the application server sends a write operation request to the core network device.

[0214] Among them, the write operation request can be used to request that the target information be written into the target A-IoT device or the target A-IoT device set. The write operation request can carry write operation auxiliary information, or the application server can send the write operation request and the write operation auxiliary information together to the core network device. The write operation auxiliary information can be used to indicate the target A-IoT device or the target A-IoT device set, target information, etc.

[0222] (6) Implicitly or explicitly indicate whether encrypted transmission is required over the air interface. For example, if encrypted transmission is required, the reader is instructed to transmit after completing the air interface encryption parameter interaction with the target A-IoT device. Otherwise, the reader is instructed to transmit without completing the air interface encryption parameter interaction with the target A-IoT device.
