It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a special hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0047] AIoT, also known as Ambient power-enabled Internet of Things (Ambient power-enabled IoT), is a kind of IoT business, in which IoT devices are powered by energy harvesting, and the IoT devices have no battery or have limited energy storage capability (for example, using a capacitor). The energy sources for energy harvesting include radio waves, light, motion, heat or other suitable energy sources.

[0048] Low-power IoT devices are a kind of IoT devices, which have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the communication energy can come from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency (RF) signals, etc. It can also be called AIoT, passive IoT device or responder device.

[0049] The signal transmission mode of the IoT device can be backscattering radio frequency (RF) signals for signal transmission; such devices can also be called electronic tags, radio frequency identification (RFID); some active tags have the ability to generate signals actively, but in order to achieve low power consumption of the device, it is generally lower than 0 dBm, for example, less than or equal to -10 dBm.

[0062]

[0063] It should be noted that the above Table 1 and Table 2 are only used to illustrate the information transmission between the reader and the tag, and the information transmission between the reader and the tag in the embodiments of the present application is not specifically limited.

[0064] The Internet of Things communication method, device and equipment provided by the embodiments of the present application will be described in detail in combination with the drawings and some embodiments and application scenarios.

[0065] Please refer to Figure 3 , Figure 3 is a flowchart of an Internet of Things communication method provided by the embodiments of the present application, as shown in Figure 3 , comprising the following steps:

[0066] Step 301, the communication device sends a first message, the first message is used to determine the transmission resource.

[0067] The communication device can be a network-side device or a terminal, or a reader of an AIoT device.

[0068] The sending of the first message can be sending the first message to one or more IoT devices, which can be AIoT devices or other IoT devices.

[0069] The first message for determining the transmission resource can be explicitly or implicitly indicating the transmission resource, or the first message is associated with the transmission resource, so that the transmission resource can be determined through the first message.

[0070] In step 302, the communication device receives a second message sent by the IoT device through the transmission resource.

[0071] The communication device receiving the second message sent by the IoT device through the transmission resource can be understood as that, after receiving the first message, the IoT device determines the transmission resource based on the first message, and sends the second message to the communication device through the transmission resource.

[0072] In the case where the first message is sent to multiple IoT devices, the transmission resource can include respective transmission resources corresponding to the multiple IoT devices, so that each IoT device can send the second message to the communication device using the respective transmission resource.

[0073] The second message can carry communication content between the IoT device and the communication device, so as to realize the communication content transmission between the IoT device and the communication device through the transmission resource. The second message can also carry identification information of the IoT device, so as to realize the inventory of the IoT device.

[0074] In some embodiments, the IoT device can be an IoT device specified by the communication device, or an IoT device specified by a core network device, or an IoT device specified by a server, which can be a specific IoT device.

[0075] In the embodiments of the present application, the communication device receives the second message sent by the IoT device through the transmission resource determined by the first message, that is, the transmission resource for transmitting the second message is determined based on the first message, so as to realize the non-competitive transmission between the communication device and the IoT device, and further improve the communication efficiency.

[0076] In the embodiments of the present application, the transmission resource is determined by the first message sent by the communication device, so that the Internet of Things device can be controlled by the communication device to realize non-contention access and transmission, improve communication efficiency, reduce time delay overhead, and reduce network complexity and overhead on the basis of ensuring transmission effect, and improve the efficiency of the communication system. For example, for AIoT devices, non-contention access and transmission can be realized under the control of the reader, ensuring communication efficiency and time delay performance.

[0077] As an optional implementation, the first message includes at least one of the following:

[0078] A paging message, a downlink (DL) message, and a reader-to-device (R2D) message.

[0079] The paging message can be understood as a message in the paging process, such as message (Msg) 0.

[0080] The DL message can also be referred to as DL signaling, and the R2D message can also be referred to as R2D signaling.

[0081] In this implementation, a plurality of messages can be used to determine the transmission resource to meet the needs of more scenarios or services.

[0082] As an optional implementation, the first message includes at least one of the following:

[0083] A first high-level signaling, at least one device identifier, indication information of the transmission resource, transmission indication information, and a temporary identifier valid within the range of the communication device.

[0084] The Internet of Things device belongs to the Internet of Things device corresponding to the at least one device identifier, the transmission indication information is used to indicate the transmission behavior between the Internet of Things device and the communication device, and the temporary identifier includes a temporary identifier of the Internet of Things device corresponding to the at least one device identifier.

[0085] The first high-level signaling can be an inventory signaling or other specific commands, such as Read, Write, Kill, and the like.

[0086] The first high-level signaling can be used to control the Internet of Things device to improve the control effect of the Internet of Things device.

[0087] In some embodiments, the first message can not include the first high-level signaling.

[0088] The above-mentioned Internet of Things device belongs to the Internet of Things device corresponding to the at least one device identifier. In other words, the Internet of Things device in step 302 is the Internet of Things device corresponding to the at least one device identifier.

[0089] The above-mentioned device identifier can be an identifier of a single Internet of Things device or a group identifier of Internet of Things devices. The above-mentioned device identifier can be a temporary or permanent identifier, which can be a temporary unique identifier within a network of a network-side device, a temporary unique identifier within a certain range allocated by a server, or a global unique identifier of the device.

[0090] In some embodiments, the device identifier in the embodiments of the present application can include at least one of the following:

[0091] A device identifier for identifying a single device, a device group identifier, and device feature information.

[0092] The above-mentioned device identifier for identifying a single device can be understood as an identifier for only one Internet of Things device.

[0093] The above-mentioned device group identifier is used to identify a group of Internet of Things devices. When the device group identifier is a temporary identifier allocated by a network-side device or a server to a group of Internet of Things devices, the device group identifier can have the same or similar format as the temporary identifier allocated to a single Internet of Things device, such as the same length of bit number, but it is necessary to clearly distinguish that the value range of the device group identifier is different from the value range of the temporary identifier of a single Internet of Things device, or carry a group identifier indication / single device identifier indication, etc., so as to facilitate the communication device to determine whether it is for a specific single device or a group of devices.

[0094] The above-mentioned device group identifier can save message overhead.

[0095] The above-mentioned device feature information is used to represent the features of the Internet of Things device, so that the device identifier can be represented by the device feature information. If the total number of devices meeting the device feature information is determined or known (for example, the network-side device or the server informs the reader) and / or the order of the devices meeting the device feature information is determined or known, the communication device can determine the specified Internet of Things device.

[0096] The above-mentioned device feature information can enable non-competitive communication for Internet of Things devices with specified device features, thereby improving the flexibility of the communication system.

[0097] In some embodiments, the above-mentioned device identifier includes:

[0098] The device identifier received by the communication device from the network-side device or the server.

[0099] The device identifier received by the communication device from the network-side device or server can be a message including the at least one device identifier sent by the network-side device or server before the communication device sends the first message, so that the network-side device or server specifies the Internet of Things device that communicates with the communication device.

[0100] In this way, the Internet of Things device that communicates with the communication device in a non-competitive manner is specified by the network-side device or server, so that the non-competitive communication is performed for the specified Internet of Things device, thereby improving the flexibility of communication.

[0101] The network-side device can be a core network device or a radio access network device. For the core network device, the core network device can initiate an inventory or command process for one or more specific Internet of Things devices, and the communication device (e.g., a reader) sends a paging message or other R2D / DL message to the specific Internet of Things device, where the message can carry the device identifier of the Internet of Things device, can also carry the dedicated resource allocated for the Internet of Things device, can also carry the temporary identifier of the Internet of Things device, and can also carry the indication of the subsequent step. The specified Internet of Things device responds on its own dedicated resource and sends a high-layer message to perform subsequent communication according to the step indicated by the communication device.

[0102] In some embodiments, the first message does not include the at least one device identifier, for example, in some scenarios, the communication device can only send the first message to the specified Internet of Things device.

[0103] The indication information of the transmission resource is used to indicate the transmission resource. For the case where there are multiple Internet of Things devices, the indication information can indicate the dedicated resource of each Internet of Things device, or multiple Internet of Things devices select their respective dedicated resources in multiple transmission resources according to a preset rule.

[0104] The indication information of the transmission resource can be used to simply and directly determine the dedicated resource of each Internet of Things device, thereby improving the accuracy of communication.

[0105] In some embodiments, when the first message does not include the indication information of the transmission resource, the transmission resource can be implicitly indicated by the first message, for example, n time slots or n symbols between the first messages are implicitly indicated as the transmission resource, or the adjacent time domain or frequency domain resource of the first message is implicitly indicated as the transmission resource, and the like.

[0106] The temporary identity valid in the range of the communication device can be understood as that the temporary identity is only valid in the range of the communication device. For example, the temporary identity is a value allocated to the communication device, such as a reader radio network temporary identity (R-RNTI).

[0107] The temporary identity including the temporary identity of the Internet of Things device corresponding to the at least one device identity can be understood as that the first message includes the temporary identity of the Internet of Things device corresponding to the at least one device identity. In the case that the first message does not include the at least one device identity, the first message can also include the temporary identity. For example, the Internet of Things device corresponding to the at least one device identity is a pre-specified or default Internet of Things device, and the first message includes the temporary identity of the pre-specified or default Internet of Things device.

[0108] Since the first message includes the temporary identity, the communication device can schedule or identify the Internet of Things device based on the temporary identity in the subsequent communication process, so as to avoid the device identity of the Internet of Things device being easily leaked by subsequent scheduling or identification based on the device identity, thereby improving the communication security.

[0109] In some embodiments, the first message can not include the temporary identity. For example, in some scenarios, the device identity can be directly used for scheduling or identification in the subsequent scheduling or identification process.

[0110] The transmission behavior between the Internet of Things device and the communication device indicated by the transmission indication information can include any transmission behavior between the communication device and the Internet of Things device from the beginning of communication to the end of communication, for example, indicating the transmission resource of the first message, or indicating the transmission resource of the second message, or indicating the content transmitted by the Internet of Things device to the communication device, or indicating the content transmitted by the communication device to the Internet of Things device, etc.

[0111] Since the first message includes the transmission indication information, the transmission behavior between the Internet of Things device and the communication device can be explicitly indicated to the Internet of Things device, so as to realize the control and selection of the communication process between the Internet of Things device and the communication device by the communication device, thereby improving the transmission reliability between the Internet of Things device and the communication device.

[0112] In some embodiments, the transmission indication information is used to indicate one of the following transmission behaviors between the Internet of Things device and the communication device:

[0113] sending a random number to the communication device;

[0114] not sending a random number to the communication device.

[0115] The communication device sends the temporary identifier to the IoT device.

[0116] The random number is used for at least one of scheduling the IoT device and identifying the IoT device.

[0117] The random number is a random number generated by the IoT device, for example, the random number can be a random number (RN) 16, or other random numbers, such as random numbers with less than or more than 16 bits.

[0118] Since the random number is used for scheduling the IoT device and identifying the IoT device, the communication device can schedule or identify the IoT device based on the random number in subsequent communication processes, so as to avoid the device identifier of the IoT device being easily leaked due to subsequent scheduling or identification using the device identifier, thereby improving communication security.

[0119] In the case where the random number is not sent to the communication device, the temporary identifier can be used for subsequent scheduling or identification.

[0120] The communication device sending the temporary identifier to the IoT device can be sending the temporary identifier to the IoT device in the first message.

[0121] In this embodiment, since the transmission behavior is indicated, the IoT device can communicate according to the indicated transmission behavior, thereby improving the transmission reliability between the IoT device and the communication device.

[0122] In some embodiments, in the case where the random number is sent to the communication device:

[0123] The second message includes the random number, and includes at least one of the identifier information of the IoT device and the first high-layer data.

[0124] Alternatively, the second message includes the random number, and at least one of the identifier information of the IoT device and the first high-layer data is sent to the communication device through a message other than the second message.

[0125] The identifier information of the IoT device can be a globally unique identifier or a high-layer identifier, for example, an electronic product code (EPC), and can be an identifier configured by a core network device or a server, such as the device identifier described in the above embodiments.

[0126] The first high-layer data can be high-layer data that needs to be sent by the IOT device to the communication device, such as high-layer data responding to the first high-layer signaling of the IOT device.

[0127] In this embodiment, the transmission of the random number, the identification information of the IOT device, and at least one of the first high-layer data through the second message can save transmission overhead.

[0128] The message other than the second message can be the fourth message described in the following embodiments.

[0129] In the above embodiments, the transmission of the random number, the identification information of the IOT device, and at least one of the first high-layer data through different messages can realize the retransmission of the identification information of the IOT device and the first high-layer data in the case of successful transmission of the random number, thereby improving the transmission reliability of the identification information of the IOT device and the first high-layer data.

[0130] It should be noted that in some embodiments, the first message can also not include the transmission indication information, for example, the transmission behavior between the IOT device and the communication device is agreed upon or pre-configured.

[0131] As an optional embodiment, the transmission resource includes at least one of the following:

[0132] The default transmission resource associated with the first message and the transmission resource indicated by the first message.

[0133] The associated default transmission resource can be a transmission resource associated with the first message based on a pre-set rule or protocol, such as a time domain or frequency domain resource adjacent to the first message, or a fixed-size transmission resource spaced apart from the first message by n time slots or symbols. The transmission overhead of the first message can be saved through the default transmission resource associated with the first message.

[0134] The transmission resource indicated by the first message can be a transmission resource explicitly or implicitly indicated by the first message.

[0135] The transmission resource indicated by the first message can make the resource configured to the IOT device more flexible.

[0136] As an optional embodiment, the communication device sends the first message, including:

[0137] The communication device sends the first message to N IOT devices.

[0138] The transmission resource includes N transmission resources, and the N transmission resources are dedicated transmission resources of the N IOT devices, respectively, and N is a positive integer.

[0139] The N IoT devices can be one or more IoT devices.

[0140] For the plurality of IoT devices, the dedicated transmission resource of each IoT device can be indicated by the first message, or the plurality of IoT devices determine their respective transmission resources based on preset rules or protocol agreements, for example, N transmission resources determine their respective dedicated transmission resources according to the ordering of the IoT devices.

[0141] In this embodiment, each IoT device is configured with a respective dedicated transmission resource to avoid transmission conflicts between IoT devices and improve transmission reliability.

[0142] As an optional embodiment, the second message includes at least one of:

[0143] The identification information of the IoT device, the first high-layer data, and the random number.

[0144] The random number is used for at least one of scheduling the IoT device and identifying the IoT device.

[0145] The identification information, the first high-layer data, and the random number are described in the corresponding description of the above embodiments, which will not be repeated here.

[0146] In this embodiment, at least one of the identification information, the first high-layer data, and the random number of the IoT device can be transmitted on the transmission resource to improve the transmission efficiency and transmission reliability of at least one of the identification information, the first high-layer data, and the random number of the IoT device.

[0147] In some embodiments, after the communication device receives the second message sent by the IoT device through the transmission resource, the method further includes:

[0148] The communication device sends a third message to the IoT device, and the third message includes at least one of:

[0149] The confirmation information of the random number and the second high-layer signaling.

[0150] The confirmation information of the random number can be an acknowledgement (ACK) of the random number.

[0151] The second high-layer signaling can be signaling other than the first high-layer signaling, such as Write, Lock, etc.

[0152] By sending the confirmation information of the random number, the IoT device can be notified of the successful transmission of the random number, thereby improving the transmission reliability between the IoT device and the communication device.

[0153] By sending the second high layer signaling, more control of the IoT device can be made to improve the control effect of the IoT device.

[0154] It should be noted that in some embodiments, the confirmation of the random number can not be sent, such as implicitly indicating the success of sending the random number by the second high layer signaling. Alternatively, in some embodiments, the IoT device defaults to the success of sending the second message after sending the second message.

[0155] In some embodiments, the third message includes confirmation information of the random number, and after the communication device sends the third message to the IoT device, the method further includes:

[0156] The communication device receives a fourth message sent by the IoT device, and the fourth message includes at least one of:

[0157] The identification information of the IoT device and the second high layer data.

[0158] The second high layer data can be high layer data other than the first high layer data, or the same high layer data as the first high layer data.

[0159] In this embodiment, the identification information of the IoT device and the high layer data can be sent after receiving the third message, thereby improving the transmission reliability of the identification information of the IoT device and the high layer data, for example, the identification information of the IoT device and the high layer data are sent after receiving the confirmation information of the random number.

[0160] As an optional embodiment, before the communication device sends the first message, the method further includes:

[0161] The communication device receives a fifth message sent by a network side device or a server, and the fifth message includes at least one of:

[0162] Third high layer signaling and at least one device identification.

[0163] The IoT device belongs to the IoT device corresponding to the at least one device identification.

[0164] The network side device can be a core network device.

[0165] The third high layer signaling can be an inventory signaling or other commands, such as Read, Write, Kill, etc. The third high layer signaling can include the first high layer signaling or the second high layer signaling.

[0166] The fifth message can represent a communication requirement of the Internet of Things device corresponding to the at least one device identifier. When the communication device receives the communication requirement of one or more specified Internet of Things devices sent by the network side device or the server, for example, receives an inventory or various command requests, the communication device identifies the corresponding Internet of Things device based on the device identifier, and communicates with the Internet of Things device.

[0167] In this embodiment, the Internet of Things device can be specified by the network side device or the server, and the communication between the Internet of Things device and the communication device can be triggered by the network side device or the server, so as to improve the flexibility of control or management of the Internet of Things device. Specifically, when the network side device or the server specifies one or more Internet of Things devices to initiate an inventory or a command, the high-layer data transmission between the communication device and the Internet of Things device can be completed through non-competitive resources, which not only ensures the success rate of communication, but also reduces the signaling overhead and processing complexity of the network side, and improves the overall efficiency, capacity and coverage of the network.

[0168] In the embodiment of the present application, the communication device sends a first message for determining a transmission resource, and the communication device receives a second message sent by the Internet of Things device through the transmission resource. In this way, since the communication device receives the second message sent by the Internet of Things device through the transmission resource determined by the first message, that is, the transmission resource for transmitting the second message is determined based on the first message, the communication device and the Internet of Things device can perform non-competitive transmission, thereby improving the communication efficiency.

[0199] The Internet of Things device sends a fourth message to the communication device, and the fourth message comprises at least one of the following:

[0200] identification information of the Internet of Things device and second high-layer data.

[0201] It should be noted that the embodiment is an implementation of the corresponding Internet of Things device in the embodiment shown in Figure 3 The specific implementation of the embodiment can be referred to the related description of the embodiment shown in Figure 3 To avoid repeated description, the embodiment will not be described again.

[0202] The following takes the communication device as reader and the Internet of Things device as AIoT device as an example, and the method provided by the embodiment of the application is exemplified through multiple embodiments:

[0203] Embodiment one:

[0204] The embodiment as a whole describes the control mechanism of the reader, specifically describes the overall framework of the scheme, and emphasizes the full control method of the reader on subsequent detailed processing.

[0205] First, the target of the communication in this embodiment is that the network side device or server needs to complete the inventory or command communication process with one or more specified AIoT devices. Among them, inventory generally refers to the inventory process, and the AIoT device receiving the inventory information needs to complete the specified information reporting, for example: reporting its own device identifier, EPC ID, so as to facilitate the network side to know the number, attribute, location and other information of the device. And the command generally can contain read, write, kill and other instructions, requiring the device to read and write specific content, or to remove the device, etc. These command instructions generally also need to be replied or confirmed by the device.

[0206] When the network side device or server needs to initiate the inventory or command process of one or more AIoT devices, it uses the core network interface or server interface to send the reader, carrying the specific content of the signaling. For example, carrying inventory or command / read / write / kill instructions, and carrying the device identifier of one or more corresponding devices. Among them, the device identifier can be a temporary unique identifier within a certain range of the network or server assigned by the network side device or server to the device, or a global unique identifier of the device. However, the latter involves certain security and privacy, so the former is more suitable for clear text transmission, and the latter needs to be sent in a security-protected manner.

[0207] Next, the reader receives the signaling of the network side device or server (i.e. the fifth message in the above embodiment), and determines from the device identifier information that this is a communication requirement for one or more specified AIoT devices. The determination method based on device identifier information can be at least one of the following:

[0208] The device identifier is one or more identifiers for a single device, which can be in any form, such as a temporary identifier or a permanent identifier, but each identifier is only for a specific device;

[0209] The device identifier needs to identify the case of group identifier. When the group identifier is a temporary identifier assigned by the network side device or server to a group of devices, the group identifier may have the same or similar format as the temporary identifier assigned to a single device, such as the same length of bit number, but the value range of the group identifier and the value range of the temporary identifier of a single device need to be clearly distinguished, or carry a group identifier indication / single device identifier indication, etc. to facilitate the reader to determine whether it is for a specific single device or a group of devices;

[0210] Device ID, if it is a group ID, when the group member information of this group ID is clear (for example, the network side device or server tells the reader), for example, the total number of devices in the group corresponding to this group ID, the sorting of each device in the group is predefined or preconfigured, for example, the group has 10 devices, and the sorting in the group is 0-9, respectively corresponding to the specific 10 devices, in this case, the reader is also clear about the number of devices and the specific corresponding situation of each device, which can also be judged as one or more specified AIoT devices;

[0211] Device ID, if it is a group ID, and the group member information in the group is not clear, for example, the total number of devices in the group is not known, and the sorting of the devices in the group is not clear, then this case cannot be judged as a specified AIoT device, in this case, the reader can use other ways to achieve the specified AIoT device;

[0212] Device feature information, if the device ID is given by the device feature information, if the total number of devices meeting the device feature information is not determined, or the sorting of the devices meeting the device feature information is not determined, in this case, it is generally judged as a non-specified AIoT device;

[0213] Device feature information, if the device ID is given by the device feature information, if the total number of devices meeting the device feature information is determined or known (for example, the network side device or server tells the reader), and / or the sorting of the devices meeting the device feature information is determined, in this case, it can be judged as a specified AIoT device.

[0214] The reader can perform certain precise control for the signaling process of sending to one or N specified AIoT devices, in order to facilitate the performance of communication efficiency and delay, the information sent by the reader to the AIoT device can be carried by paging message or other R2D / DL signaling, and the content includes at least one of the following:

[0215] High-level signaling content (i.e. the first high-level command in the above embodiment), such as inventory command, Command command, command command content, such as Read, Write, Kill, etc.

[0216] Device ID information (i.e. at least one device ID in the above embodiment), such as device ID or device ID list;

[0217] The dedicated resource allocated for each specified AIoT device, when there is only one AIoT device, the dedicated resource is directly for the UE, if it is multiple devices, the correspondence between the dedicated resource list and multiple AIoT devices takes a default or specified way, for example, N dedicated resources, N time slots, or N frequency resources, or N resource blocks, according to the arrangement order in the device identification list, and N devices are one-to-one corresponding in order, the device in the first position in the device identification list corresponds to the first dedicated resource, and so on, the device in the n position in the device identification list corresponds to the n dedicated resource; The specified way, for example, device identification 1 carries the corresponding dedicated resource or resource identification, and so on, each device identification displays carries or indicates the corresponding resource;

[0218] The specified AIoT device is allocated a valid temporary identifier in the reader for subsequent data scheduling transmission, which can be allocated for one device, multiple devices, or all devices involved in this command are allocated respectively, and each device corresponds to its unique temporary identifier.

[0219] The specified device indicates the subsequent steps (i.e. the transmission indication information in the above embodiment), for example, the execution mode of the command, which may have multiple steps to choose from, indicating the AIoT device to execute mode 1 (i.e. the way provided in embodiment two below), or other ways, etc., or indicating how to send step 1, the content in Msg1, etc.

[0220] The specified AIoT device initiates the subsequent communication process according to the indication of the reader after receiving the paging, R2D / DL signaling of the reader, to complete the entire signaling process.

[0221] Embodiment two:

[0222] The communication mode of this embodiment can be called mode 1, where the network side device or server sends a request to the reader, as analyzed in detail in embodiment one, the focus of this embodiment is the interaction steps between the reader and the AIoT device, as shown in Figure 5 The steps include:

[0223] First step: reader sends Msg0 message (i.e. the first message in the above embodiment) to the AIoT device, which can be a paging message or other R2D message type, carrying the core network or server high-layer signaling content, such as inventory, Command (such as Read, Write, Kill, etc.) and the device identifier or device identifier list for this signaling, such as containing one or more device identifiers for a single device, and optionally, implicitly or explicitly assigning a dedicated transmission resource for each AIoT device involved.

[0224] For example, if there is only one device, the default Msg1 resource after Msg0 is dedicated to the device, and if there is more than one device, multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, each corresponding to each device in the AIoT device ID in order, specifically one-to-one.

[0225] Second step: after receiving the Msg0 message, the specified AIoT device acquires its own dedicated transmission resource in order and sends Msg1 message (i.e. the second message in the above embodiment) to the reader on its own dedicated resource, where Msg1 message is a response to the high-layer message content in Msg0, such as EPC ID feedback for inventory, AIoT device feedback for Read information, AIoT device feedback for Write message, etc. In short, EPC ID and / or high-layer data content are included in Msg1 message and sent to the reader on the specified dedicated resource.

[0226] Next: since Msg1 is a dedicated resource, there is no conflict and competition, and on each device's dedicated resource, the reader reads the feedback Msg1 message of the device and sends the high-layer EPC ID or high-layer data content in Msg1 message to the core network or server.

[0227] In particular, if the expected UE's Msg1 message is not correctly received on the specified dedicated resource, the reader can judge that the process has failed, and subsequent retransmission of new Msg0 and reception of Msg1 message can continue to complete the communication process for the failed device;

[0228] For AIoT devices, under the control of Msg0 information and parameters, Msg1 is sent without any failure detection or active recovery, and the reader is fully responsible for process failure judgment and retransmission, etc. to ensure the reliability and completion of information transmission.

[0229] Embodiment Three:

[0230] The communication mode of this embodiment can be referred to as Mode 2, in which the network side device or server sends a request to the reader, as analyzed in detail in Embodiment 1; the focus of this example is the interaction steps between the reader and the AIoT device. Specifically, on the basis of Embodiment One, another detailed interaction step between the reader and the AIoT device is given to complete the entire signaling flow, as shown in Figure 6 The steps include:

[0231] The first step (similar to Embodiment Two): the reader sends a Msg0 message (i.e., the first message in the above embodiments) to the AIoT device, which can be a paging message or other R2D message type, carrying the core network or server high-layer signaling content, such as inventory, Command (Read, Write, Kill, etc.), and also carrying the device identifier or device identifier list for this signaling, such as containing one or more AIoT device IDs for a single device, and optionally, using implicit or explicit methods to allocate dedicated transmission resources for each AIoT device involved;

[0232] For example, if there is only one device, then the default Msg1 resource after Msg0 is dedicated to the device, and if there is more than one device, multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, each corresponding to each device in the AIoT device ID in order, specifically one-to-one correspondence;

[0233] In particular, an indication can also be carried in Msg0, requiring the AIoT device to send its own random number RN16 in Msg1 for subsequent scheduling. This is one obvious difference between Embodiments Two and Three regarding Msg0, i.e., whether Msg1 needs to send the device's RN16 or whether there is an indication of subsequent scheduling in Msg0. Of course, explicitly distinguishing the Msg0 of Embodiments Two and Three by signaling is a coexistence of the two modes. It is also possible that the standard adopts a default mode, i.e., does not carry the subsequent indication or RN16 indication in Msg0, and the AIoT device follows the implementation of Embodiments Two or Three as specified in the standard.

[0234] Second step: the designated AIoT device acquires its own dedicated resource in sequence after receiving the Msg0 message, and sends the Msg1 message (i.e. the second message in the above embodiment) to the reader on the dedicated resource, wherein the Msg1 message is a response to the high-layer message content in Msg0, for example, for inventory, the AIoT device can feedback its EPC ID, for Read information, the AIoT device feedbacks the data content required to be read, for Write message, the AIoT device can feedback the confirmation information of write completion, etc. In short, the EPC ID and / or high-layer data content are contained in the Msg1 message and sent to the reader on the designated dedicated resource.

[0235] Since the explicit subsequent scheduling indication or RN16 indication is carried in Msg0, or the mode in embodiment three is selected as the default mode, in Msg1, the AIoT device also carries a random number RN16, which is randomly generated or generated after randomization operation according to its device ID, for example, hash function. The AIoT device carries RN16 in Msg1 and sends it to the reader.

[0236] Next: since Msg1 is a dedicated resource, there is no conflict and competition, on the dedicated resource of each device, the reader reads the feedback Msg1 message of the device, and sends the high-layer EPC ID or high-layer data content in the Msg1 message to the core network or server.

[0237] The reader reads the RN16 in Msg1, judges whether the RN16 conflicts with the random number of other devices, and in the case of no conflict, confirms that the RN16 can be used as the unique identifier of the device under this reader, for the subsequent scheduling and transmission of the AIoT device.

[0238] Third step: the reader sends the Msg2 message (i.e. the third message in the above embodiment) to the AIoT device, which contains the confirmation of the RN16 sent by the device in Msg1, meaning that the reader correctly receives the Msg1 message, and the RN16 of the device is legal and can be used for subsequent identification and scheduling; optionally, other high-layer signaling information can also be carried in Msg2.

[0239] The AIoT device receives the RN16 confirmation of Msg2, and considers that the access process this time is successful. Stores the RN16 and uses it as the subsequent scheduling and identification. If there is other message in Msg2, it is processed and responded accordingly. Or use RN16 as the identification of other message transmission and scheduling after Msg2.

[0240] If the AIoT device does not receive the RN16 confirmation of Msg2 within a certain time, for example, the next R2D time slot, or after the timer / window expires, the AIoT device can consider this communication as a failure.

[0241] The Reader can determine that the AIoT device fails in the case that it does not successfully receive Msg1 on the dedicated resource and retransmit Msg0 to ensure reliability and success rate. Or, the Reader fails to send Msg2, the AIoT device does not correctly store and confirm RN16 as its own legal identity, and the Reader defaults to scheduling the device with RN16 as the identifier in the subsequent scheduling because there is no feedback after sending Msg2. In the subsequent scheduling, there is no expected response, so it can be known that the failure occurs and the process of synchronizing RN16 is initiated again.

[0242] Embodiment Four:

[0243] The communication mode of the embodiment can be referred to as mode 3, in which the network side device or server sends a request to the reader, as analyzed in detail in Embodiment 1; the focus of this example is the interaction steps between the reader and the AIoT device. Specifically, based on Embodiment One, another detailed interaction step between the reader and the AIoT device is given to complete the entire signaling flow, as shown in Figure 7 The steps include:

[0244] Step 1 (similar to Embodiment Two): The reader sends a Msg0 message (i.e., the first message in the above embodiment) to the AIoT device, which can be a paging message or other R2D message type. The message carries high-layer signaling content of the core network or server, such as inventory, Command (Read, Write, Kill, etc.), and also carries the device identifier or device identifier list for this signaling, such as containing one or more AIoT device IDs for a single device. Optionally, each AIoT device involved is assigned a dedicated transmission resource in an implicit or explicit manner;

[0245] For example, if there is only one device, the default Msg1 resource after Msg0 is dedicated to the device. If there is more than one device, multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, which correspond to each device in the AIoT device ID in order, specifically one-to-one.

[0246] In particular, in Msg0, a unique identifier assigned to the AIoT device (i.e., the temporary identifier in the above embodiment) can also be carried, which is used for subsequent scheduling. When there are multiple devices, a unique identifier can be assigned to each device, or assigned to some devices and not assigned to others, as long as the identity is clear.

[0247] This is a significant difference between the Msg0 in Embodiments 2, 3, and 4. Embodiment 2 is more suitable for single transmission, and Embodiments 3 and 4 both assign RN16 to the device for subsequent scheduling and device identification, which is convenient for subsequent data transmission. The difference between Embodiments 3 and 4 is that Embodiment 3 selects RN16 by the AIoT device and then confirms the legality by the reader, while Embodiment 4 directly assigns a temporary identifier (such as RN16) by the reader. Since the reader can ensure uniqueness when assigning, Embodiment 4 is more efficient.

[0248] Step 2: After receiving the Msg0 message, the designated AIoT device acquires its own dedicated resource in order and sends a Msg1 message (i.e., the second message in the above embodiment) to the reader on the dedicated resource, where the Msg1 message is a response to the high-level message content in Msg0. For example, for inventory, the AIoT device can feedback its EPC ID, for Read information, the AIoT device feedbacks the data content required to be read, for Write message, the AIoT device can feedback the confirmation information of write completion, etc. In summary, in the Msg1 message, the EPC ID and / or high-level data content are included and sent to the reader on the designated dedicated resource.

[0249] The AIoT device receives the temporary identifier assigned by the reader, stores it, and uses it as the device identifier and identification for subsequent other signaling transmission and scheduling.

[0250] Optionally, the AIoT device can also carry the temporary identifier in the Msg1 message again as the identifier of this Msg1. Or since Msg1 is a dedicated resource, the identity can be identified and the temporary identifier can be omitted.

[0251] Embodiment 5:

[0252] The communication method of this embodiment can be called method 4, where the network side device or server sends a request to the reader, as analyzed in detail in Embodiment 1. The focus of this example is the interaction steps between the reader and the AIoT device. Based on Embodiment 1, another detailed interaction step between the reader and the AIoT device is given to complete the entire signaling flow, as shown in Figure 8 The steps include:

[0253] The first step (similar to example 2): the reader sends a Msg0 message (i.e. the first message in the above examples) to the AIoT device, which can be a paging message or other R2D message type, carrying the core network or server high-layer signaling content, such as inventory, Command (Read, Write, Kill, etc.), and also carrying the device identifier or device identifier list for this signaling, such as containing one or more AIoT device IDs for individual devices, and optionally, using implicit or explicit methods to allocate dedicated transmission resources for each AIoT device involved.

[0254] For example, if there is only one device, the default Msg1 resource after Msg0 is dedicated to the device, and if there is more than one device, multiple resource blocks can be carried in Msg0, such as N time slots, N frequencies, and N time-frequency resource blocks, each corresponding to each device in the AIoT device ID in order, specifically one-to-one correspondence.

[0255] In particular, unlike examples two, three, and four, in this embodiment, it is expected that only the RN16 of the AIoT device will be sent in Msg1, rather than directly carrying the EPC ID or high-layer data, so if this embodiment needs to coexist with other embodiments, the reader needs to explicitly indicate in Msg0 whether to send high-layer information or RN16 directly in Msg1, or to indicate implicitly in Msg0, such as when the resource is large, meaning that high-layer information can be sent directly, and when the resource is small, meaning that RN16 is sent first; or, for this embodiment five, directly through standard regulations, choose one of the categories to enter the standard specification behavior, and the UE performs according to the specified behavior, there is no difference.

[0256] The second step: after receiving the Msg0 message, the designated AIoT device acquires its own dedicated resource in order and sends a Msg1 message (i.e. the second message in the above examples) to the reader on its own dedicated resource, carrying the RN16 of the device in the Msg1 message, which is randomly generated or generated after randomization operation according to its own device ID, such as a hash function, and the AIoT device carries the RN16 in Msg1 and sends it to the reader.

[0257] Next: Since Msg1 is all dedicated resources, there is no conflict and competition, on the dedicated resource of each device, the reader reads the feedback Msg1 message of the device, the Reader reads RN16 in Msg1, judges whether RN16 conflicts with the random number of other existing devices, and in the case of no conflict, confirms that RN16 can be used as the unique identifier of the device under this reader for subsequent scheduling and transmission of the AIoT device.

[0258] Third step: The Reader sends the Msg2 message (i.e. the third message in the above embodiment) to the AIoT device, which contains the confirmation of the RN16 sent by the device in Msg1, meaning that the reader correctly receives the Msg1 message, and the RN16 of the device is legal and can be used for subsequent identification and scheduling.

[0259] The AIoT device receives the RN16 confirmation of Msg2, and considers that the access process this time is successful. Store RN16 and use it as the subsequent scheduling and identification. If there is other information in Msg2, then process and respond accordingly. Or use RN16 as the identification of other message transmission and scheduling after Msg2.

[0260] If the AIoT device does not receive the RN16 confirmation of Msg2 within a certain time, for example, the next R2D time slot, or after the timer / window timeout, the AIoT device can consider that the communication fails this time.

[0261] The Reader can determine that the AIoT device fails in the case of not successfully receiving Msg1 on the dedicated resource, and re-sends Msg0 subsequently to ensure reliability and success rate. Or, the Reader fails to send Msg2, the AIoT device does not correctly store and confirm RN16 as its legal identification, and the Reader defaults to scheduling the device with RN16 as the identification in the subsequent scheduling because there is no feedback after sending Msg2. If there is no any expected response in the subsequent scheduling, it can be known that the failure occurs, and the process of synchronizing RN16 is initiated again.

[0262] Fourth step: The device that successfully receives its RN16 confirmed initiates a new UL, D2R message (i.e. the fourth message in the above embodiment) transmission, where the message is a response to the high-level message content in Msg0, for example, for inventory, the AIoT device can feedback its EPC ID, for Read information, the AIoT device feedbacks the data content required to be read, for Write message, the AIoT device can feedback the confirmation information of write completion, etc. In short, in Msg1 message, EPC ID and / or high-level data content are contained and sent to the reader on the specified dedicated resource.

[0263] Next: Since this message is also a dedicated resource transmission, there is no conflict and competition, the reader reads the feedback message of the device, and sends the high layer EPC ID or high layer data content in the message to the core network or server;

[0264] If there is a subsequent other signaling process, the reader and the AIoT device rely on RN16 for scheduling transmission.

[0265] The above embodiments give a communication method of AIoT designated device, so that the AIoT device can be accessed and transmitted under the control of the reader, ensuring the communication efficiency and the delay overhead performance, so as to reduce the network complexity and overhead and improve the system efficiency on the basis of ensuring the transmission effect.
