[0042] The embodiments of the present disclosure provide a communication method and apparatus that can solve the problem of how to page a specific A-IOT device in an A-IOT scenario.

[0043] In a first aspect, an embodiment of the present disclosure proposes a communication method, which is executed by a first device, and the method includes: sending a first command to one or more second devices, wherein the first command defines first information for indicating the second device to be paged; wherein the second device is an ambient Internet of Things device in an ambient Internet of Things (A-IOT) scenario, and the first device is a network device or an intermediate node in the ambient Internet of Things scenario.

[0044] In the above embodiment, in the A-IOT scenario, a first command is sent through a first device, wherein first information is defined in the first command, and the device to be paged is indicated by the first information, so that the A-IOT device receives the first command and determines whether it is a specific A-IOT device to be paged through the first information defined in the first command, thereby realizing paging of a specific A-IOT device, and solving the problem of how to page a specific A-IOT device through the first command in the A-IOT scenario.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the first command includes the first information, and the first information is a first identifier, used to indicate that the second device to be paged is a first specific device, and the first specific device refers to an environmental Internet of Things device among the environmental Internet of Things devices serving as the second device; the first command includes the first information, and the first information is a mask MASK, used to indicate that the second device to be paged is a second specific device, and the second specific device refers to at least one group of environmental Internet of Things devices among the environmental Internet of Things devices serving as the second device; the first command does not include the first information, used to indicate that the second device to be paged is a third specific device, and the third specific device refers to all second devices that have received the first command.

[0046] It should be understood that the expression "defining the first information in the first command" can be understood as indicating the inclusion relationship with the first information in the first command in some way, for example, reserving an information field for carrying the first information in the first command, or setting a field related to the first information in the first command. Specifically, for example, defining the first information in the first command can refer to whether the first information is included in the first command, and if so, what type of first information is included. In some embodiments, defining the first information in the first command can refer to including the first information in the first command, and the first information is a mask MASK; in some embodiments, defining the first information in the first command can refer to including the first information in the first command, and the first information is a first identifier; in some embodiments, defining the first information in the first command can refer to not including the first information in the first command. Depending on the situation of defining the first information in the first command, the situation of the second device to be paged can be indicated, for example, whether to page a specific second device, a group or several groups of second devices, or all second devices.

[0047] In the above embodiment, the first command may carry first information, which is a first identifier and is used to page a specific A-IOT device among the second devices that receive the first command; or, the first command carries first information, which is a MASK mask and can be used to select a group or multiple groups of specific A-IOT devices among the second devices that receive the first command; or, the first command does not carry the first information and can be used to select all second devices that receive the first command as specific A-IOT devices, thereby solving the problem of how to page a specific A-IOT device through the first command in the A-IOT scenario.

[0048] In combination with some embodiments of the first aspect, in some embodiments, the first command further includes second information, where the second information is used to identify a command type of the first command, and the command type is used to indicate that the first command is a paging command.

[0096] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, a first device and a second device. The number and configuration of devices shown in Figure 1 are for example purposes only and do not limit the present disclosure. In actual applications, two or more first devices and two or more second devices may be included. The communication system 100 shown in Figure 1 includes, for example, a first device 101 and a second device 102.

[0097] In some embodiments, the second device 102 can be one or more ambient Internet of Things (Ambient Internet of Things, also called Ambient IOT or A-IOT) devices in the ambient Internet of Things scenario. The A-IOT device does not need to generate energy by itself, but can collect energy, such as collecting energy based on the surrounding environment or signals sent by surrounding devices, and can communicate based on the collected energy. The device also does not need to be configured with batteries or replace batteries. In other words, the ambient Internet of Things device needs to collect radio waves sent by the surrounding environment or surrounding devices to obtain energy before it can drive itself to work. The ambient Internet of Things device has the characteristics of low memory, low processing power, low power, small data transmission, and massive deployment. The ambient Internet of Things device can be maintenance-free and have a long service life.

[0098] In some embodiments, the device types of the A-IOT devices include a first type and a second type. Among them, the A-IOT device of the first type has energy storage, no independent signal generation / amplification function, and the uplink transmission relies on backscatter transmission. Optionally, the peak power consumption of the A-IOT device of the first type is less than 1 microwatt (uw). The A-IOT device of the second type has energy storage, an independent signal amplification function, and the uplink transmission is based on an internally generated signal or the uplink transmission relies on backscatter transmission. Optionally, the peak power consumption of the A-IOT device of the second type is less than or equal to several hundred uw. Exemplarily, the first type refers to a device with energy storage and no independent signal generation and / or amplification function; the second type refers to a device with energy storage and a signal amplification function. Exemplarily, the first type refers to a device with a peak power consumption of less than 1 microwatt (uw); the second type refers to a device with a peak power consumption of less than or equal to several hundred uw (such as 100uw or 200uw, etc.). It should be noted that, in some embodiments, the several hundred uW is, for example, 100 uW or 200 uW, etc., which is an example given to facilitate the understanding of those skilled in the art. That is, the peak power consumption is less than or equal to other hundreds of uW, and this disclosure does not make a specific limitation on this.

[0099] In some embodiments, the device type of an A-IOT device can be divided into a first type and a second type. The first type of A-IOT device can refer to a "backscattering" A-IOT device, and the second type of A-IOT device can refer to a "non-backscattering" A-IOT device, where "backscattering" can, for example, refer to sending signals based on backscattering (or uplink transmission relies on backscattering transmission); and "non-backscattering" can, for example, refer to actively sending signals (or uplink transmission is based on internally generated signals).

[0100] In some embodiments, the device type of the A-IOT device can be divided into a first type, a second type, and a third type. Among them, the A-IOT device of the first type has energy storage, no independent signal generation / amplification function, and the uplink transmission relies on backscatter transmission. Optionally, the peak power consumption of the A-IOT device of the first type is less than 1 microwatt (uw). The A-IOT device of the second type has energy storage, an independent signal amplification function, and the uplink transmission is based on an internally generated signal. Optionally, the peak power consumption of the A-IOT device of the second type is less than or equal to several hundred uw. The A-IOT device of the third type has energy storage, an independent signal amplification function, and the uplink transmission relies on backscatter transmission. Optionally, the A-IOT device of the third type is less than or equal to the peak power consumption of several hundred uw. It should be noted that, in some embodiments, the several hundred uw is, for example, 100 uw or 200 uw, etc., which is an example given to facilitate the understanding of those skilled in the art, that is, the peak power consumption is less than or equal to other hundreds of uw, and this disclosure does not make a specific limitation on this.

[0101] In some embodiments, the first device 101 may be a network device or an intermediate node in an A-IOT scenario. In some embodiments, the first device 101 may perform an inventory or page on the first device 101.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0109] It's important to note that in today's IoT networks, traditional IoT devices are often powered by conventional batteries with limited lifespans, negatively impacting the user experience. The astronomical growth of IoT networks, coupled with the proliferation of IoT devices, has pushed maintenance expenses, including labor and battery costs, to a whole new level. Billions of conventional batteries are discarded each year, with only a small fraction effectively recycled, negatively impacting the Earth's ecosystem. Maintaining IoT network operations and replacing batteries can be extremely challenging in some extreme environmental conditions. Battery-free IoT communications have been proposed, promising improved network performance and sustainability, while expanding their application scenarios. Furthermore, battery-free communications are more environmentally friendly and safer for children and the elderly. By eliminating traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0110] In the 5G era, various LPWA (Low Power Wide Area) technologies, such as MTC (Machine Type Communication), NB-IoT (Narrow Band Internet of Things), and RedCap (Reduced Capability), have been developed to meet the growing needs of vertical fields. These LPWA technologies achieve low cost, low power consumption, and large-scale connectivity, which can meet the requirements of many applications. However, there are still many use cases and applications that cannot be solved in the following situations. First, devices driven by traditional batteries are not applicable, such as in extreme environmental conditions (such as high voltage, extremely high / low temperature, and humid environments). Second, maintenance-free devices are required (for example, traditional batteries that do not need to be replaced in the device). Finally, ultra-low complexity, very small device size / form factor (such as mm thickness), and longer life cycle are required.

[0111] Ambient-powered IoT is a promising technology that can address the aforementioned unmet needs. An ambient-powered IoT device is an IoT device powered by energy harvesting, either without a battery or with limited energy storage capabilities (e.g., using capacitors), by harvesting radio waves, light, motion, heat, or any other suitable power source.

[0112] Energy harvested from the environment can power sensor nodes for data transmission and wireless communication. Current mainstream low-power IoT communication chips (such as BLE, LoRa, and NB-IoT) consume tens or even hundreds of milliwatts of power for both transmission and reception. However, ambient energy harvesting only yields microwatts, making it inadequate for these nodes. Therefore, new wireless communication technologies are needed to reduce communication energy consumption to tens or even below ten microwatts. Backscatter communications is currently the mainstream approach. Backscatter communications is a key technology for building a green, energy-efficient, and flexibly deployable future IoT, and a crucial means of achieving the "Intelligent Connection of Everything."

[0113] Backscatter communication is a modulation and transmission technology designed with extremely low power consumption, which utilizes the principle of backscattering of radio frequency signals. For example, when a radio frequency signal reaches the surface of an object, a portion of it will be reflected. The sending node adjusts the matching between the receiving antenna and the impedance according to the information to be sent, thereby enhancing the reflection of the incident radio frequency signal and modulating the acquired sensing data onto the reflected signal to complete the transmission of the data. This process is similar to that of a reflector. Compared with other communication technologies, backscatter communication does not require a complex radio frequency structure, reduces the use of devices such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters, and does not require complex baseband processing. Therefore, it can simplify terminal design and significantly reduce the cost of terminal nodes.

[0114] Backscatter communication has been widely used in RFID (radio frequency identification) systems, with numerous large-scale commercial applications. Its operating principle is that a receiver (typically an RFID reader) transmits a radio frequency excitation signal, activating a passive node (typically an RFID tag). The tag then uses backscatter communication to modulate its information onto the radio frequency signal. The reader then receives the reflected signal from the passive tag and demodulates it, achieving information transmission.

[0115] Currently, RFID technology also has numerous drawbacks, such as limited coverage (the wireless signal experiences double-path fading during the round-trip communication process, resulting in high path loss and a short effective communication range), single-channel transmission, the need for strict tag alignment, and a lack of power control. RFID technology still has significant room for improvement in communication. Integration with 3GPP communication technologies is needed to improve the wireless communication performance of RFID technology in the passive IoT.

[0116] To conserve power and reduce device complexity in communication systems, new devices, such as the Ambient Internet of Things (A-IoT) devices, have been introduced. These A-IoT devices require energy from radio waves emitted by the surrounding environment or surrounding devices before they can operate. Therefore, before sourcing energy, A-IoT devices are typically powered off, meaning they are disconnected from the network. To address this, communication systems must support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to expedite data communication.

[0117] In some embodiments, the present disclosure implements a wireless communication design based on backscatter technology to communicate with an ambient energy device (also referred to as an ambient IoT device, i.e., the first device in this article). Optionally, the above-mentioned ambient IoT device (also called an Ambient IOT device, or an A-IOT device) can be applicable to a variety of different communication architectures in a communication system, wherein Figures 2A-2E are schematic diagrams of the architecture when an A-IoT device communicates with a network device and / or a terminal according to an embodiment of the present disclosure. Optionally, as shown in Figure 2A, data or signals can be directly received and sent between the A-IoT device (i.e., the Ambient IoT device in Figure 2A) and the network device (such as a base station (BS)).

[0118] Optionally, as shown in FIG2B , the A-IoT device and the network device (such as a base station (BS)) can indirectly receive and send data or signals through an intermediate node, where the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

[0119] Optionally, as shown in FIG2C , uplink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and downlink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, which can be, for example, a relay, an IAB device, a terminal, or a repeater.

[0120] Optionally, as shown in FIG2D , downlink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node.

[0121] Optionally, as shown in FIG2E , data can be directly received and sent between the A-IoT device and the terminal (or user equipment (UE)), and the terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0122] Based on the above content, the embodiments of the present disclosure provide a communication method and apparatus that can solve the problem of how to page a specific A-IOT device through a first command in an A-IOT scenario.

[0123] Figure 3A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3A, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0124] Step S3101: The first device 101 sends a first command.

[0125] In some embodiments, the first command is sent by the first device 101. For example, in an A-IOT scenario, the first device 101 sends the first command, and accordingly, one or more second devices 102 in the A-IOT scenario can receive the first command sent by the first device 101. In some embodiments, the second device 102 can be an A-IOT device in the A-IOT scenario, and the first device 101 can be a network device or an intermediate node in the A-IOT scenario.

[0126] In some embodiments, the first command may be a paging command. In some embodiments, the first command defines first information for indicating the second device to be paged. The second device to be paged may be one of the one or more second devices 102 (i.e., the second device to be paged may be one of the second devices that received the first command), or the second device to be paged may be at least one group of second devices among the one or more second devices 102 (i.e., the second device to be paged may be one or more groups of second devices among the second devices that received the first command), or the second device to be paged may be all second devices 102 that received the first command. In some embodiments, the terms "paging command," "selection command," and "search command" may be used interchangeably. In some embodiments, the terms "paging," "selection," and "search" may be used interchangeably.

[0127] In some embodiments, the first command sent by the first device 101 to the second device 102 may include first information, wherein the first information may be a first identifier or a MASK (mask), or may not include the first information. That is: the first command sent by the first device 101 to the second device 102 may carry a first identifier or a MASK (mask), or may carry neither the first identifier nor the MASK (mask). In some embodiments, the first command includes first information, and the first information is a first identifier, which can be used to indicate that the second device to be paged is a first specific device, that is: the first identifier can be an identifier of the first specific device or a unique identifier of the first specific device, such as an EPC (Electronic Product Code) code or other identifier, which is not specifically limited in this disclosure. Among them, the first specific device can be an A-IOT device among the environmental Internet of Things devices serving as the second device. That is: the first device 101 in the A-IOT scenario can send a first command to one or more A-IOT devices in the A-IOT scenario. The first information included in the first command can be a first identifier, and the first identifier can be the identifier of a specific A-IOT device among the one or more A-IOT devices, so as to facilitate paging the specific A-IOT device, thereby achieving the purpose of paging a specific A-IOT device through the first command.

[0128] In some embodiments, the first command includes first information, and the first information is a MASK mask. Exemplarily, the above-mentioned MASK mask can be a File (document) or a bitstring (bit string, also called bit string). In some embodiments, the first command includes first information, and the first information is a MASK mask, which can be used to indicate that the second device to be paged is a second specific device, and the second specific device refers to at least one group of A-IOT devices among the A-IOT devices serving as the second device. That is: the first device 101 in the A-IOT scenario can send a first command to one or more A-IOT devices in the A-IOT scenario. The first information included in the first command can be a MASK mask, which can be used to identify at least one group of specific A-IOT devices among the one or more A-IOT devices, so as to facilitate paging of at least one group of specific A-IOT devices, thereby achieving the purpose of paging at least one group of specific A-IOT devices (such as a group of A-IOT devices or multiple groups of A-IOT devices) through the first command.

[0129] In some embodiments, the first command does not include the first information (that is, the first command carries neither a MASK nor a MASK mask), which is used to indicate that the second device to be paged is a third specific device, and the third specific device refers to all second devices that have received the first command. That is, the first device 101 in the A-IOT scenario can send a first command to one or more A-IOT devices in the A-IOT scenario, and the first command carries neither a MASK nor a MASK mask, so as to facilitate paging all A-IOT devices that have received the first command, thereby achieving the purpose of paging all A-IOT devices through the first command.

[0130] In some embodiments, the first command may further include second information, where the second information is used to identify a command type of the first command, where the command type is used to indicate that the first command is a paging command. For example, a second information is defined in the first command, where the second information may identify a command type of the first command, where the command type may be used to indicate that the first command is a paging command, so that the second device 102 can determine whether the first command is a paging command based on the command type.

[0131] In some embodiments, the second information included in the first command for paging the first specific device is the same as the second information included in the first command for paging the second specific device and the second information included in the first command for paging the third specific device. That is, the first command for paging a specific A-IOT device, the first command for paging at least one group of specific A-IOT devices, and the first command for paging all A-IOT devices can share a common command type (command type). Exemplarily, the first command can include a first identifier, a MASK mask, or neither the first identifier nor the MASK mask. The first command including the first identifier and the first command including the MASK mask, as well as the first command including neither the first identifier nor the MASK mask, can share the same command type, for example, to indicate that the first command is a paging command.

[0132] In some embodiments, the above-mentioned first command may further include indication information, which may be used to indicate that the first command includes the first information and the first information is a first identifier or a MASK, or does not include the first information (i.e., it carries neither the first identifier nor the MASK); wherein the indication information is a first value, used to indicate that the first command includes the first information, and the first information is a first identifier; the indication information is a second value, used to indicate that the first command includes the first information, and the first information is a MASK; the indication information is a third value, used to indicate that the first command does not include the first information. The first value may be 00, the second value may be 01, and the third value may be 10 or 11. Exemplarily, an indication information may be defined in the first command to indicate whether the first command includes the first identifier or the MASK mask, or includes neither the first identifier nor the MASK. For example, the number of bits of the indication information may be 2, 00 indicates that the first command includes the first information, and the first information is the first identifier (or, the first command includes the first identifier), 01 indicates that the first command includes the first information, and the first information is a MASK mask (or, the first command includes a MASK mask), 10 or 11 indicates that the first command does not include the first information (or, the first command carries neither the first identifier nor the MASK). Alternatively, the indication information may have other value options to indicate that the first command carries the first identifier or the MASK, or carries neither the first identifier nor the MASK, and this disclosure does not specifically limit this.

[0133] Step S3102: The indication information in the first command is a first value, and the second device 102 determines that the first command includes first information, and the first information is a first identifier.

[0134] In some embodiments, the second device 102 receives the first command sent by the first device 101, and can determine whether the first command includes the first information based on the indication information in the first command (or determine whether the first command carries the first information). If the first command includes the first information, determine whether the first information is a first identifier or a MASK mask, that is: the second device 102 can determine based on the indication information whether the first command carries the first identifier or the MASK mask, or carries neither the first identifier nor the MASK mask. Exemplarily, if the indication information in the first command is a first value, the second device 102 can determine that the first command includes the first information and the first information is the first identifier (that is, it can be determined that the first command carries the first identifier), so that the second device 102 can determine whether the second device 102 is the first specific device based on the first identifier, that is, determine whether the second device 102 is the specific A-IOT device to be paged.

[0135] Step S3103: The second device 102 determines whether the second device 102 is the first specific device based on the first identifier included in the first command.

[0136] In some embodiments, the second device 102 determines that the first command sent by the first device 101 includes first information and the first information is a first identifier. The second device 102 can determine whether the second device 102 is a first specific device (i.e., a specific A-IOT device associated with the first identifier) ​​based on the first identifier included in the first command. Exemplarily, the second device 102 matches its own identifier with the first identifier. If the identifier of the second device 102 is consistent (or the same) as the first identifier, the second device 102 can determine that it is the first specific device (i.e., a specific A-IOT device associated with the first identifier), that is, the second device 102 can determine that it is the specific A-IOT device to be paged. Exemplarily, if the identifier of the second device 102 is inconsistent (or different) from the first identifier, the second device 102 can determine that it is not the first specific device, that is, the second device 102 can determine that it is not the specific A-IOT device to be paged.

[0137] In step S3104, the indication information in the first command is the second value, and the second device 102 determines that the first command includes first information, and the first information is MASK.

[0138] In some embodiments, when the second device 102 receives the first command sent by the first device 101, it can determine whether the first command includes the first information based on the indication information in the first command (or determine whether the first command carries the first information). If the first command includes the first information, determine whether the first information is a first identifier or a MASK mask, that is: the second device 102 can determine based on the indication information whether the first command carries the first identifier or the MASK mask, or carries neither the first identifier nor the MASK mask. Exemplarily, if the indication information in the first command is the second value, the second device 102 can determine that the first command includes the first information and the first information is a MASK mask (that is, it can be determined that the first command carries a MASK mask), so that the second device can determine whether the second device 102 is included in the second specific device based on the MASK mask, that is, determine whether the second device 102 is included in the at least one group of specific A-IOT devices to be paged.

[0139] In step S3105 , the second device 102 determines whether the second device 102 is included in the second specific device based on the MASK included in the first command.

[0140] In some embodiments, the second device 102 determines that the first command sent by the first device 101 includes first information and the first information is a MASK. The second device 102 can determine whether the second device 102 is included in the second specific device based on the MASK included in the first command. Exemplarily, the second device 102 matches itself with the value of the MASK. If the second device 102 matches the value of the MASK, the second device 102 can determine that it is included in the second specific device (i.e., the at least one group of specific A-IOT devices identified by the MASK), that is, the second device 102 can determine that it is included in the at least one group of specific A-IOT devices to be paged, that is, the second device 102 belongs to the specific A-IOT device to be paged. Exemplarily, if the second device 102 does not match the value of the MASK, the second device 102 can determine that it is not included in the second specific device (i.e., the at least one group of specific A-IOT devices identified by the MASK), that is: the second device 102 can determine that it is not included in the at least one group of specific A-IOT devices to be paged, that is, the second device 102 does not belong to the specific A-IOT device to be paged.

[0141] Step S3106: The indication information in the first command is the third value, and the second device 102 determines that the first command does not include the first information.

[0142] In some embodiments, the second device 102 receives a first command sent by the first device 101 and can determine whether the first command includes the first information (or determine whether the first command carries the first information) based on the indication information in the first command. If the first information is included in the first command, determine whether the first information is a first identifier or a MASK mask, that is, the second device 102 can determine based on the indication information whether the first command carries the first identifier or the MASK mask, or carries neither the first identifier nor the MASK mask. Exemplarily, if the indication information in the first command is the third value, the second device 102 can determine that the first command does not include the first information, that is, it can be determined that the first command carries neither the first identifier nor the MASK mask.

[0143] In step S3107 , the second device 102 determines that it is included in the third specific device.

[0144] In some embodiments, the second device 102 that receives the first command sent by the first device 101 determines that the first command does not include the first information, that is: the first command sent by the first device 101 carries neither the first identifier nor the MASK mask, then the second device 102 can determine that it is included in the third specific device, that is, all second devices that receive the first command are A-IOT devices to be paged.

[0145] In step S3108, the second device 102 determines that it is the first specific device, and then the second device 102 sends a response message.

[0146] In some embodiments, the above-mentioned response message may be sent by the second device 102 to the first device 101. In some embodiments, the second device 102 determines that it is the first specific device, and the second device 102 sends a response message to the first device 101. Correspondingly, the first device 101 receives the response message sent by the second device 102. That is, the second device 102 determines that it is the specific A-IOT device to be paged, and the second device 102 sends a response message to the first device 101. Exemplarily, the response message may be an ACK (Acknowledge) message, and the ACK message may carry an identifier of the second device 102. For example, the identifier of the second device 102 included in the ACK message may be an EPC code, that is, the identifier of the second device 102 included in the ACK message is the same as the above-mentioned first identifier.

[0147] Optionally, in some embodiments, if the second device 102 determines that it is not the first specific device, the second device 102 does not send a response message to the first device 101.

[0148] It is worth noting that in some embodiments, in the A-IOT scenario, there is an inventory process between the first device (i.e., the network device or intermediate node in the A-IOT scenario) and the point-to-point command (such as the third command directed to a specified A-IOT device, such as the access command, including but not limited to: read command, write command, lock command, kill command, etc.) to the A-IOT device, that is, the A-IOT devices are first classified into groups through paging, and then one or more groups of these A-IOT devices are inventoried through inventory. During the inventory process, the A-IOT device needs to report the identifier of the A-IOT device (such as an EPC code or a random number similar to a handle, etc., or other identifier) ​​to the first device to realize the communication authentication between the first device and the A-IOT device. After the first device and the A-IOT device complete the communication authentication, the first device will send the third command (such as the access command, including but not limited to: read command, write command, lock command, kill command, etc.) to the specified A-IOT device (i.e., an A-IOT device among the A-IOT devices that have completed the communication authentication). Exemplarily, the second device 102 determines that it is included in the second specific device or the third specific device. Then, after subsequently receiving the second command (such as a query command or an inquiry / inventory command) sent by the first device 101, the second device 102 can, under certain conditions, generate a random number (such as a random number from 0 to 2 to the power of Q) based on the first parameter (such as the Q value), and use the random number as the initial value of the counter. Each time a queryrep command (a command in the second command) is received, the value of the counter is subtracted by 1. When the value of the counter is reduced to a certain value (such as 0), the second device 102 can send a response message to the first device 101, and the response message can carry the random number. That is to say, if the second device 102 determines that it is included in the second specific device or the third specific device, the second device 102 may not immediately respond to the first command sent by the first device 101, but may wait to receive the second command (such as a query command) sent by the first device 101, and then respond to the second command sent by the first device 101 to complete the communication authentication between the second device 102 and the first device 101. Subsequently, the third command (such as an access command, including but not limited to: a read command, a write command, a lock command, a kill command, etc.) may be directly sent to the second device 102 that has completed the communication authentication.

[0149] In some embodiments, the embodiments of the present disclosure support directly locating and selecting an A-IOT device through paging. For example, the first device sends a first command to one or more A-IOT devices in the A-IOT scenario. The first information carried in the first command is a first identifier. The first identifier is used to indicate that the second device to be inventoried is one of the one or more A-IOT devices. The A-IOT device that receives the first command determines that it is the A-IOT device based on the first identifier. Then, the A-IOT device sends a response message to the first device. The response message can be an ACK message. The ACK message can carry the identifier of the A-IOT device (such as an EPC code or a random number similar to a handle, etc., or other identifiers), so that the communication authentication between the first device and the A-IOT device can be completed. In this way, the first device can directly send a third command (such as an access command, including but not limited to: read command, write command, lock command, kill command, etc.) to the A-IOT device. That is to say, by carrying the first identifier in the first command, a specific A-IOT device can be paged directly, so that the specific A-IOT device can report the identifier of the specific A-IOT device to the first device to complete communication authentication, so that the first device can send a third command (such as an access command, including but not limited to: a read command, a write command, a lock command, a kill command, etc.) to the specific A-IOT device. It can be seen that by adopting this solution, before the first device executes the third command (such as an access command, including but not limited to: a read command, a write command, a lock command, a kill command, etc.) on a specified A-IOT device, there is no need to perform an inventory process. The specified A-IOT device can be determined in the paging stage, and the third command (such as an access command, including but not limited to: a read command, a write command, a lock command, a kill command, etc.) can be sent directly to the specified A-IOT device subsequently.

[0165] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 3A .

[0166] Figure 3B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3B, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0167] Step S3201: The first device 101 sends a first command.

[0168] In some embodiments, the first command is sent by the first device 101. For example, in an A-IOT scenario, the first device 101 sends the first command, and accordingly, one or more second devices 102 in the A-IOT scenario can receive the first command sent by the first device 101. In some embodiments, the second device 102 is an A-IOT device in the A-IOT scenario, and the first device 101 is a network device or an intermediate node in the A-IOT scenario.

[0169] In some embodiments, the first command may be, for example, a paging command. In some embodiments, the first command defines first information for indicating a second device to be paged. The second device to be paged may be one of the one or more second devices 102 (i.e., the second device to be paged may be one of the second devices that received the first command), or the second device to be paged may be at least one group of second devices among the one or more second devices 102 (i.e., the second device to be paged may be one or more groups of second devices among the second devices that received the first command), or the second device to be paged may be all second devices 102 that received the first command.

[0170] In some embodiments, the first command sent by the first device 101 to the second device 102 may include first information, wherein the first information may be a first identifier or a MASK (mask), or may not include the first information. That is: the first command sent by the first device 101 to the second device 102 may carry a first identifier or a MASK (mask), or may carry neither the first identifier nor the MASK (mask). In some embodiments, the first command includes first information, and the first information is a first identifier, which can be used to indicate that the second device to be paged is a first specific device, that is: the first identifier can be an identifier of the first specific device or a unique identifier of the first specific device, such as an EPC (Electronic Product Code) code or other identifier, which is not specifically limited in this disclosure. Among them, the first specific device can be an A-IOT device among the environmental Internet of Things devices serving as the second device. That is: the first device 101 in the A-IOT scenario can send a first command to one or more A-IOT devices in the A-IOT scenario. The first information included in the first command can be a first identifier, and the first identifier can be the identifier of a specific A-IOT device among the one or more A-IOT devices, so as to facilitate paging the specific A-IOT device, thereby achieving the purpose of paging a specific A-IOT device through the first command.

[0171] In some embodiments, the first command includes first information, and the first information is a MASK mask. Exemplarily, the above-mentioned MASK mask can be a File (document) or a bitstring (bit string, also called bit string). In some embodiments, the first command includes first information, and the first information is a MASK mask, which can be used to indicate that the second device to be paged is a second specific device, and the second specific device refers to at least one group of A-IOT devices among the A-IOT devices serving as the second device. That is: the first device 101 in the A-IOT scenario can send a first command to one or more A-IOT devices in the A-IOT scenario. The first information included in the first command can be a MASK mask, and the MASK mask can be used to identify at least one group of specific A-IOT devices among the one or more A-IOT devices, so as to facilitate paging of at least one group of specific A-IOT devices, thereby achieving the purpose of paging at least one group of specific A-IOT devices (such as a group of A-IOT devices or multiple groups of A-IOT devices) through the first command.

[0172] In some embodiments, the first command does not include the first information (that is, the first command carries neither a MASK nor a MASK mask), which is used to indicate that the second device to be paged is a third specific device, and the third specific device refers to all second devices that have received the first command. That is, the first device 101 in the A-IOT scenario can send a first command to one or more A-IOT devices in the A-IOT scenario, and the first command carries neither a MASK nor a MASK mask, so as to facilitate paging all A-IOT devices that have received the first command, thereby achieving the purpose of paging all A-IOT devices through the first command.

[0173] In some embodiments, the first command may further include second information, where the second information is used to identify a command type of the first command, where the command type is used to indicate that the first command is a paging command. For example, a second information is defined in the first command, where the second information may identify a command type of the first command, where the command type may be used to indicate that the first command is a paging command, so that the second device 102 can determine whether the first command is a paging command based on the command type.

[0174] In some embodiments, the second information included in the first command for paging the first specific device is different from the second information included in the first command for paging the second specific device, and the second information included in the first command for paging the third specific device. In other words, the first command for paging a specific A-IOT device, the first command for paging at least one group of specific A-IOT devices, and the first command for paging all A-IOT devices may include different command types.

[0175] In some embodiments, the second information included in the first command used to page the above-mentioned first specific device is a fourth value, used to indicate that the first command includes the first information and the first information is a first identifier; the second information included in the first command used to page the above-mentioned second specific device is a fifth value, used to indicate that the first command includes the first information and the first information is MASK; the second information included in the first command used to page the above-mentioned second specific device is a sixth value, used to indicate that the first command does not include the first information. For example, taking the fourth value as 00, the fifth value as 01, and the sixth value as 10 or 11 as an example, if the second information included in the first command (or the second information in the first command) is 00, it indicates that the first command includes the first information and the first information is the first identifier, that is, the first command is a command for paging the above-mentioned first specific device; if the second information included in the first command (or the second information in the first command) is 01, it indicates that the first command includes the first information and the first information is a mask, that is, the first command is a command for paging the above-mentioned second specific device; if the second information included in the first command (or the second information in the first command) is 10 or 11, it indicates that the first command does not include the first information (the first command carries neither the first identifier nor the mask), that is, the first command is a command for paging the above-mentioned third specific device. Alternatively, the second information may have other value options to indicate that the first command carries the first identifier or the mask, or carries neither the first identifier nor the mask, and this disclosure does not specifically limit this.

[0176] Step S3202: The second device 102 receives a first command sent by the first device 101 and the second information included therein is a fourth value, and determines that the first command sent by the first device 101 includes first information and the first information is a first identifier.

[0177] In some embodiments, when the second device 102 receives a first command sent by the first device 101, it may determine whether the first command includes the first information (or determine whether the first command carries the first information) based on the second information included in the first command. If the first command includes the first information, it may determine whether the first information is a first identifier or a mask. That is, the second device 102 may determine, based on the second information, whether the first command carries the first identifier or the mask, or carries neither the first identifier nor the mask. Exemplarily, if the second information in the first command is the fourth value, the second device 102 may determine that the first command includes the first information and that the first information is the first identifier, thereby facilitating the second device 102 determining, based on the first identifier, whether the second device 102 is the first specific device, i.e., whether the second device 102 is the specific A-IOT device to be paged.

[0178] Step S3203: The second device 102 determines whether the second device 102 is the first specific device based on the first identifier included in the first command.

[0179] The optional implementation of step S3203 can refer to the optional implementation of step S3103 in Figure 3A and other related parts in the embodiment involved in Figure 3A, which will not be repeated here.

[0180] Step S3204: The second device 102 receives the first command sent by the first device 101 and the second information included therein is the fifth value, and determines that the first command sent by the first device 101 includes the first information and the first information is MASK.

[0181] In some embodiments, when the second device 102 receives a first command sent by the first device 101, it may determine, based on the second information included in the first command, whether the first command includes the first information (or whether the first command carries the first information). If the first command includes the first information, it may determine whether the first information is a first identifier or a mask. In other words, the second device 102 may determine, based on the second information, whether the first command carries the first identifier or the mask, or carries neither the first identifier nor the mask. For example, if the second information in the first command is the fourth value, the second device 102 may determine that the first command includes the first information and that the first information is a mask (i.e., it may determine that the first command carries the mask). This facilitates the second device determining, based on the mask, whether the second device 102 is included in the second specific device, i.e., whether the second device 102 is included in the at least one group of specific A-IOT devices to be paged.

[0182] In step S3205 , the second device 102 determines whether the second device 102 is included in the second specific device based on the MASK included in the first command.

[0183] The optional implementation of step S3205 can refer to the optional implementation of step S3105 in Figure 3A and other related parts in the embodiment involved in Figure 3A, which will not be repeated here.

[0184] Step S3206: The second device 102 receives the first command sent by the first device 101 and the second information included therein is the sixth value, and determines that the first command does not include the first information.

[0185] In some embodiments, the second device 102 receives the first command sent by the first device 101, and can determine whether the first command includes the first information based on the second information included in the first command (or determine whether the first command carries the first information). If the first command includes the first information, determine whether the first information is a first identifier or a MASK mask, that is: the second device 102 can determine based on the second information whether the first command carries the first identifier or the MASK mask, or carries neither the first identifier nor the MASK mask. Exemplarily, if the second information in the first command is the sixth value, the second device 102 can determine that the first command does not include the first information (that is, it can be determined that the first command carries neither the first identifier nor the MASK mask), so that the second device can determine whether the second device 102 is included in the third specific device based on the first command, that is, determine whether the second device 102 is included in all A-IOT devices to be paged.

[0186] In step S3207 , the second device 102 determines that it is included in the third specific device.

[0187] In some embodiments, the second device 102 that receives the first command sent by the first device 101 determines that the first command does not include the first information, that is: the first command sent by the first device 101 carries neither the first identifier nor the MASK mask, then the second device 102 can determine that it is included in the third specific device, that is, all second devices that receive the first command are A-IOT devices to be paged.

[0188] In step S3208, the second device 102 determines that it is the first specific device, and then the second device 102 sends a response message.

[0189] The optional implementation of step S3206 can refer to the optional implementation of step S3106 in Figure 3A and other related parts in the embodiment involved in Figure 3A, which will not be repeated here.

[0273] Step S5301: Receive a first command sent by a first device, where the first command defines first information for indicating a second device to be paged.

[0274] In some embodiments, the second device is an environmental Internet of Things device in an environmental Internet of Things scenario, and the first device is a network device or an intermediate node in the environmental Internet of Things scenario.

[0275] In some embodiments, the first command includes first information, and the first information is a first identifier, used to indicate that the second device to be paged is a first specific device, and the first specific device refers to an environmental Internet of Things device among the environmental Internet of Things devices serving as the second device; the first command includes first information, and the first information is a mask MASK, used to indicate that the second device to be paged is a second specific device, and the second specific device refers to at least one group of environmental Internet of Things devices among the environmental Internet of Things devices serving as the second device; the first command does not include the first information, used to indicate that the second device to be paged is a third specific device, and the third specific device refers to all second devices that have received the first command.

[0276] In some embodiments, the first command further includes second information, where the second information is used to identify a command type of the first command, and the command type is used to indicate that the first command is a paging command.

[0277] In some embodiments, the second information included in the first command for paging the first specific device is the same as the second information included in the first command for paging the second specific device and the second information included in the first command for paging the third specific device.

[0278] In some embodiments, the first command also includes indication information; wherein the indication information is a first value, used to indicate that the first command includes first information, and the first information is a first identifier; the indication information is a second value, used to indicate that the first command includes first information, and the first information is MASK; the indication information is a third value, used to indicate that the first command does not include the first information.

[0283] For optional implementations of the second device side method involved in the embodiments of the present disclosure, please refer to the descriptions of the relevant steps of the second device 102 in Figures 3A and 3B above, which will not be repeated here.

[0284] Figure 6 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 6, the method involved in the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0285] Step S6101: The first device 101 sends a first command to one or more second devices 102.

[0286] In some embodiments, first information is defined in the first command to indicate the device to be paged; wherein the second device is an ambient Internet of Things device in an ambient Internet of Things scenario, and the first device is a network device or an intermediate node in the ambient Internet of Things scenario.

[0287] The optional implementation of step S6101 can refer to the optional implementation of step S3101 in Figure 3A, step S3201 in Figure 3B, and other related parts in the embodiments involved in Figures 3A and 3B, which will not be repeated here.

[0288] In some embodiments, the above method may include the method described in the above embodiments of the first device side, the second device side, etc., which will not be repeated here.

[0289] It is worth noting that the embodiments of the present disclosure provide a paging command design method in an A-IOT scenario, which solves the problem of how to select one or at least a group of specific A-IOT devices or all A-IOT devices through a selection or paging command in an A-IOT scenario. In some embodiments, the selection or paging command can carry a first identifier or a mask.

[0290] In some embodiments, the first identifier can be an identifier or a unique identifier of the A-IOT device, and can also be called an A-IOT device identifier, or can have other names. The MASK mask can be a file or a bitstring. The first identifier is carried in the selection or paging command to select / page a specific A-IOT device. The MASK mask is carried in the selection or paging command to select / page at least one group of A-IOT devices, such as a group of A-IOT devices, or multiple groups of A-IOT devices or all A-IOT devices.

[0291] In some embodiments, if the selection or paging command carries neither the first identifier nor the MASK mask, it is used to select or page all A-IOT devices.

[0292] In some embodiments, a common selection or paging command is defined. The selection or paging command for paging a specific A-IOT device and the selection or paging command for paging a group / all A-IOT devices share the same command type.

[0293] In some embodiments, the selection or paging command may carry a first identifier or a MASK mask, or may carry neither the first identifier nor the MASK mask. The selection or paging command carrying the first identifier, the selection or paging command carrying the MASK mask, and the selection or paging command carrying neither the first identifier nor the MASK mask share the same command type, for example, to indicate that this is a paging command.

[0294] In some embodiments, an indicator bit (i.e., the indication information in this article) is defined to indicate whether the selection or paging command carries the first identifier or the MASK mask, or neither the first identifier nor the MASK mask, and specifically to indicate whether the paging command is used to select or page an A-IOT device, a group of A-IOT devices, or all A-IOT devices. For example, a 2-bit indicator bit, 00 indicates that the selection or paging command carries the first identifier, 01 indicates that the selection or paging command carries the MASK mask, and 10 or 11 indicates that the selection or paging command carries neither the first identifier nor the MASK mask. Or there are other indication forms, which are not limited. The A-IOT device uses this indicator bit to distinguish whether the selection or paging command carries the first identifier or the MASK mask, or neither the first identifier nor the MASK mask.

[0295] In some embodiments, three types of paging commands are defined. A paging command for paging a specific A-IOT device, a paging command for paging at least a group of A-IOT devices, and a paging command for paging all A-IOT devices are associated with different command types. Exemplarily, one paging command carries a first identifier, one carries a mask, and one carries neither the first identifier nor the mask.

[0296] In some embodiments, a paging command that carries a first identifier and a paging command that carries a MASK mask have different command types from a paging command that carries neither the first identifier nor the MASK mask. Exemplarily, different command types are used to indicate whether the paging command carries the first identifier, the MASK mask, or neither the first identifier nor the MASK mask. The A-IOT device uses different command types to distinguish whether the paging command carries the first identifier, the MASK mask, or neither the first identifier nor the MASK mask.

[0297] The embodiments of the present disclosure further provide apparatuses for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing each step performed by the first device in any of the above methods. For another example, another apparatus is provided that includes units or modules for implementing each step performed by the second device in any of the above methods.

The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
