Description

Device identification method and apparatus Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] The Internet of Things (IoT) has been a hot topic in the wireless communications field in recent years, with an increasing number of devices hoping to connect to improve productivity and quality of life. By further reducing the size, complexity, and power consumption of IoT devices, tens or even hundreds of billions of IoT devices can be deployed to build an ecosystem. However, powering these devices with batteries or direct power requires manual battery replacement, charging, and circuit maintenance, resulting in high maintenance costs and serious, even harmful, environmental impacts.

[0003] Currently, existing devices in the wireless communications field all require power supplies, such as batteries that require periodic replacement or recharging. However, emerging markets require the introduction of new IoT technologies to support network access for battery-free devices. These battery-free devices may or may not have the ability to store energy, but instead operate by harvesting energy from the environment. These devices are known as Ambient IoT devices, or AIoT devices or A-IoT devices for short.

[0004] Currently known RFID (Radio Frequency Identification) devices have the characteristics of ultra-low complexity, small size, and no need for battery power. However, they are limited in their reading range to a few meters. They usually require manual scanning with handheld readers or the use of expensive RFID doors to read and write to the devices. In addition to incurring manpower, time, and deployment costs, they also cannot achieve seamless network coverage of all devices within the coverage area.

[0005] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0006] Summary of the Invention

[0007] At the RAN level in 3GPP Release 18, Ambient IoT was studied, defining relevant terminology and a scope framework for further discussion. 3GPP Release 19 includes work items led by RAN2 for Ambient IoT research. For example, to implement DO-DTT (Device-Originated–Device-Terminated Triggered) and DT (Device-Terminated) services, signaling processes such as paging, random access, and data transmission need to be studied.

[0008] Based on the current progress of 3GPP's Ambient IoT work, it's unclear how to regulate the signaling interaction between the network and Ambient IoT devices. Because Ambient IoT devices lack a stable power supply, are simple in structure, have a narrow bandwidth, and utilize low-cost internal crystal oscillators with low precision and limited signal processing capabilities, many functions supported by traditional wireless communication terminals cannot be directly applied to Ambient IoT devices. For example, due to power supply and accuracy issues, Ambient IoT devices may be unable to activate their timing devices to transmit necessary information at designated network locations, effectively preventing them from performing uplink transmissions as scheduled by the network.

[0009] Therefore, 3GPP needs to define specific signaling or commands and processes for communication between the network and Ambient IoT devices to implement services such as DO-DTT / DT. For example, these processes include: how the network pages Ambient IoT devices; how Ambient IoT devices randomly access the network; how data is transmitted between the network and Ambient IoT devices; and what necessary signaling or commands the network needs to identify Ambient IoT devices within its coverage area.

[0010] The inventors discovered that traditional wireless communication devices all have stable power supplies, allowing them to permanently store identifiers negotiated with the network and synchronize with the network to monitor valid information. For example, idle devices can still periodically monitor network paging messages. Even devices that have lost synchronization or have just been powered on can synchronize with the network through a random access process, which allows the network to identify different devices and assign them unique identifiers. Only devices recognized by the network can communicate with the network, such as for uplink and downlink data transmission.

[0011] However, for Ambient IoT devices, the typical response method is mainly backscattering. That is, they can only reply using backscattering when they receive a valid signal. They cannot actively initiate random access requests to the network. Therefore, newly deployed Ambient IoT devices cannot be recognized by the network.

[0012] Due to the simple structure and limited energy storage capacity of Ambient IoT devices, they may not be able to store the network-assigned identifiers for a long time. This means that the network may not be able to page the designated terminal device using traditional paging methods. Furthermore, due to the lack of stable long-term power supply and the limited accuracy of crystal oscillators, Ambient IoT devices struggle to achieve synchronous communication with the network. This means that the network cannot schedule and specify resources (such as time and / or frequency) for data transmission with Ambient IoT devices.

[0044] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in FIG1 , a communication system 100 includes a first device 101 and a second device 102 .

[0045] The first device 101 communicates with the second device as an identifier, a reader, or an interrogator. For example, the first device is a network device or an intermediate node; the second device is an AIoT device.

[0051] The following describes the scenarios of the embodiments of the present application through more specific examples, but the present application is not limited thereto.

[0052] FIG2 is a schematic diagram of a topology of a communication system according to an embodiment of the present application, wherein (a) and (b) in FIG2 are two different topologies.

[0053] As shown in Figure 2(a), a network device (e.g., a base station) can communicate directly with an AIoT device, sending signals directly to the AIoT device or receiving signals directly from the AIoT device. Communications between the network device and the AIoT device include AIoT data and / or signaling. Furthermore, in this topology, the network device that sends signals to the AIoT device may be a different network device than the one that receives signals from the AIoT device.

[0054] As shown in (b) of Figure 2, a network device (such as a base station) can also pass through an intermediate node and use the intermediate node to send signals to the AIoT device or use the intermediate node to receive signals from the AIoT device, that is, the AIoT device communicates bidirectionally with an intermediate node between a network device and the AIoT device.

[0055] In the embodiment of the present application, the intermediate node can be a relay device (relay), IAB node (IAB node), terminal device (UE), repeater (repeater), etc. with AIoT capabilities. The intermediate node transmits AIoT data and / or signaling between the AIoT device and the network device (base station).

[0056] In the embodiments of the present application, a network device may send signals / information / configurations to an AIoT device, or an AIoT device may receive signals / information / configurations from a network device.

[0057] In the embodiments of the present application, when an AIoT device sends a signal / information to a network device, or when a network device receives a signal / information from an AIoT device, the AIoT device may send the signal and the network device may receive it directly, or the AIoT device may send the signal and the network device may receive it via an intermediate node, or the AIoT device may send the signal and the network device may receive it via other methods. Unless otherwise specified, the present application is not limited to this.

[0058] Embodiments of the first aspect

[0059] An embodiment of the present application provides a device identification method, which is applied to a first device, such as the first device 101 in Figure 1 or the network device in Figure 2 (a) or the intermediate node in Figure 2 (b).

[0060] FIG3 is a schematic diagram of a device identification method according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0061] 301: The first device sends first information to the second device, where the first information is at least used to identify the second device; and

[0062] 302: The first device receives second information from the second device, where the second information is information sent by the second device based on the first information. In other words, the uplink second information is triggered by the downlink first information.

[0063] In some embodiments, the first device, acting as an identifier, reader, or interrogator, communicates directly with the second device, acting as an AIoT device, over an air interface.

[0064] For example, the first device is:

[0065] Network equipment, such as a base station (BS); or

[0066] User Equipment (UE), such as an intermediate node (Intermediate Node) or intermediate UE.

[0067] That is to say, the device identification method of the embodiment of the present application is applicable to the situation where the network device communicates directly with the AIoT device, such as the scenario shown in (a) of Figure 2; it is also applicable to the situation where the network device communicates with the AIoT device through an intermediate node, such as the scenario shown in (b) of Figure 2.

[0068] In some embodiments, “identification” may also be referred to as “inventory”, that is, “identification of the second device (AIoT device)” may also be referred to as “inventory of the second device (AIoT device)”.

[0069] In some embodiments, the network's identification process (also referred to as an identification process, identification procedure, or identification step) of the second device (AIoT device) is used to at least obtain information about the AIoT device, such as the ID of the AIoT device. Furthermore, the network can implement services such as DO-DTT / DT with the AIoT device.

[0070] In some embodiments, the identification process for the second device (AIoT device) is the first process or includes the first process or is applied to the first process, or the first process is implemented by the identification process for the second device.

[0071] For example, the first process includes at least one of the following processes:

[0072] Paging;

[0073] The paging preparation phase or the phase of obtaining the information of the second device (e.g., the ID of the AIoT device);

[0074] Random Access;

[0075] The preparation phase for random access or the phase of obtaining information of the second device (e.g., the ID of the AIoT device);

[0076] Pre-stage for Data transmission.

[0077] In addition, in some embodiments, the identification process for the second device (AIoT device) can also be used only for the network to take inventory of AIoT devices within the coverage area, such as whether the status of existing AIoT devices has changed, whether there are newly deployed AIoT devices, etc.

[0078] In some embodiments, the network replaces traditional uplink scheduling by sending an indication to the AIoT device before expecting to receive a transmission from the second device (AIoT device). This not only indicates the resources (such as time and / or frequency) for sending uplink transmissions to the network to the AIoT device, but also provides the AIoT device with a trigger / activation signal for backscattering of uplink transmissions, thereby achieving the above process.

[0079] In some embodiments, the second device as the identification object is all AIoT devices belonging to the cell of the network device and / or covered by the intermediate node, or the second device as the identification object is a group of specified (specific) AIoT devices among all AIoT devices belonging to the cell of the network device and / or covered by the intermediate node.

[0080] In some embodiments, the identification process of the second device (AIoT device) is triggered by a network node (Network Node).

[0081] The network node may be: a core network (CN); or

[0082] Network equipment, such as a base station (BS); or

[0083] Intermediate node, such as intermediate terminal equipment (Intermediate UE).

[0084] In some embodiments, as shown in FIG3 , the method may further include:

[0085] 303: The first device decides to identify the second device.

[0086] In some embodiments, the first device decides to identify the second device (AIoT device) based on signaling from an upper-level network node; or, the first device actively initiates identification of the second device (AIoT device).

[0087] For example, if the first device is a network device and the upper network node is the core network, then the network device as the first device can decide to identify the second device (AIoT device) based on the signaling from the core network. For example, when the core network detects the DO-DTT / DT service, it triggers the first device to identify (inventory) the AIoT device through the air interface, such as requesting the base station to page all or specified (specific) AIoT devices, requesting the base station to feedback information about the AIoT device, instructing the base station to inventory the AIoT device, requesting to establish a connection with the AIoT device (read / write AIoT device), etc. The base station receives the AIoT device-related signaling from the core network and can serve as an identifier in the AIoT device identification (inventory) process to directly identify (inventory) the AIoT device.

[0088] For example, if the first device is an intermediate node (intermediate UE) and the upper network node is a network device, then the intermediate node of the first device decides to identify the second device (AIoT device) based on the signaling from the network device. For example, the base station can forward the relevant content of the AIoT device-related signaling received from the core network to the intermediate UE as the identifier, instructing the intermediate UE to identify (inventory) the AIoT device.

[0089] For example, the first device may also proactively initiate an identification (inventory) process for the second device (AIoT device) as needed, and update the AIoT device database based on the identification (inventory) results.

[0090] The following describes in detail the identification process of the second device (AIoT device).

[0091] FIG4 is an interactive diagram of the recognition process of an embodiment of the present application. As shown in FIG4 , the recognition process includes:

[0092] 401: The core network or network device sends AIoT device-related signaling to the first device (identifier). For example, when the first device is a network device, the core network sends AIoT device-related signaling to the first device. When the first device is an intermediate node, the network device forwards the AIoT device-related signaling from the core network to the first device.

[0093] 402: The first device (identifier) ​​decides to start an identification session process with the second device (AIoT device) based on AIoT device-related signaling from the core network or network device; for example, the identification session process includes one or more rounds of identification;

[0094] Alternatively, the first device (identifier) ​​actively decides to start the second device (AIoT device) identification session process. For example, the first device (identifier) ​​decides to start the second device (AIoT device) identification session process based on an application message (such as the start of an application on the first device). For another example, the first device (identifier) ​​periodically starts the second device (AIoT device) identification session process based on the configuration of the upper network node. In this case, step 401 can be omitted;

[0095] 403: The first device (identifier) ​​sends third information to the second device (AIoT device), and the first information includes at least the third information. In addition, the third information is at least used to indicate whether the second device participates in the identification session process, and / or the third information is at least used to indicate that the first device starts the identification session process for the second device; for example, the third message is a paging message sent by the first device (identifier) ​​to the second device (AIoT device); for example, the third information includes a specific field stored by the AIoT device.

[0096] 404: The second device (AIoT device) determines whether to participate in the current identification session based on the third information. For example, the second device (AIoT device) determines whether to participate in the identification session based on the content of the third information and / or the built-in information of the AIoT device, such as updating a flag or stored content indicating whether to participate in the session based on whether the content of the third information matches the built-in information.

[0097] 405: The first device (identifier) ​​sends fourth information to the second device (AIoT device). The first information includes at least the fourth information, which includes an indication of whether the second device participates in the current round of identification, relevant parameters for backscattering by the second device, and at least one of the first resource parameters, and / or the fourth information is at least used to indicate the start of a new round of identification process in the identification session of the first device to the second device; the first resource parameter is at least used to indicate, calculate, or obtain the amount of resources for the second device to send a response, feedback, or uplink reply to the first device;

[0098] For example, the fourth information is a random access indication, which is used to indicate the start of a new round of second device (AIoT device) identification process in the identification session process, which includes a backscatter link frequency (BLF) or a parameter for calculating the backscatter link frequency (BLF); and / or, the fourth information may also include a first resource parameter, which is used to indicate / calculate / obtain the number of resources for the second device (AIoT device) to send a response / feedback / uplink reply to the first device (identifier), such as the number of time units used for feedback.

[0099] In some embodiments, the fourth information content is included in the third information as new third information, or the content of the third information and the content of the fourth information are sent to the second device together, which is used to indicate whether the second device (AIoT device) participates in the identification session process, and also indicates the start of a new round of identification process for the second device (AIoT device), and may also indicate whether the second device (AIoT device) that has been successfully identified participates in this round of identification process.

[0100] In some embodiments, the first device (identifier) ​​uses the new third information to replace the third information and the fourth information in the first round of identification process of the second device (AIoT device) identification session, or new third information can be used in each round of identification process.

[0101] In some embodiments, the new third information may also include fifth information, which is used to indicate whether the second device (AIoT device) that has been successfully identified participates in this round of identification.

[0102] In some embodiments, the identification process may further include the following optional operations:

[0103] 406: The first device sends seventeenth information to the second device (AIoT device), where the seventeenth information is at least used to update the fourth information.

[0104] For example, in an identification session with a second device (AIoT device), the first device (identifier) ​​reconfigures the identification parameters, such as updating the first resource parameters, by sending the seventeenth information to the second device (AIoT device). The second device (AIoT device) adjusts the configuration according to the seventeenth information, such as randomly re-selecting a new resource location to be fed back to the first device (identifier) ​​based on the new first resource parameters.

[0105] Operation 406 is an optional operation and is indicated by a dashed line in FIG4 .

[0106] After the second device (AIoT device) receives the fourth information or the new third information containing the fourth information or updates the fourth information according to the seventeenth information, the identification process further includes:

[0107] 407: The second device (AIoT device) randomly selects and stores the location of resources for sending eighth information to the first device based on the fourth information. The eighth information includes at least a first identifier related to the second device, and the first identifier is generated by the second device. The first identifier includes at least a random number generated by the second device.

[0108] For example, the second device (AIoT device) participating in the identification session process randomly selects a resource location (such as a time slot) from the available resources to feedback to the first device (identifier) ​​based on the fourth information, such as updating the stored feedback resource location.

[0109] If the randomly selected feedback resource location is not reached, the second device (AIoT device) continues to wait.

[0110] In some embodiments, the identification process may further include the following optional operations:

[0111] 408: The first device (identifier) ​​sends the seventh information to the second device (AIoT device), where the first information at least includes the seventh information, and the seventh information is at least used to indicate whether the first device sends the sixth information.

[0112] 409: When the seventh information indicates that the first device (identifier) ​​does not send the sixth information, the second device (AIoT device) autonomously updates or judges or waits for the location of the resources used to send the eighth information to the first device (identifier), that is, there is no need to receive the sixth information to trigger the update of the feedback resource location.

[0113] Operations 408 and 409 are optional operations and are indicated by dashed lines in FIG. 4 .

[0114] 410: The first device (identifier) ​​sends sixth information to the second device (AIoT device), where the first information at least includes the sixth information, and the sixth information is at least used to indicate new resources to the second device.

[0115] For example, the first device (identifier) ​​sends the sixth information, such as New Resource Indication, to the second device (AIoT device), which is used to indicate the arrival of new resources to the second device (AIoT device). After receiving the sixth information, the second device (AIoT device) updates the stored feedback resource location, for example, by subtracting 1 from the feedback resource location.

[0116] Next, the recognition process also includes:

[0117] 411: When the location of the randomly selected resource for sending the eighth information is reached, for example, the value or count of the randomly generated or updated feedback resource location is 0, the second device (AIoT device) sends the eighth information to the first device (identifier), and the second information includes at least the eighth information, and the eighth information includes at least a first identifier associated with the second device, and / or the eighth information is sent by the second device via backscatter. The first identifier includes at least a random number generated by the second device.

[0118] For example, when the second device (AIoT device) finds that the feedback resource location has arrived, for example, the second device randomly generates or updates the feedback resource location value or count to 0 based on the fourth information or the new third information or the sixth information or the seventeenth information, it sends the eighth information to the first device (identifier), such as the Random Access Request, which is used to feedback the first identifier (also called the first valid identifier, such as the random access identifier) ​​of the identification process to the first device (identifier), such as a string of random numbers generated by the second device (AIoT device), and the second device (AIoT device) stores the first identifier.

[0119] 412: The first device (identifier) ​​stores the eighth information, for example, stores the first identifier related to the second device, such as a random number generated by the second device.

[0120] 413: The first device (identifier) ​​sends ninth information to the second device (AIoT device), where the first information at least includes the ninth information, and the ninth information at least includes the first identifier, and the first identifier at least includes a random number generated by the second device.

[0121] For example, after receiving the eighth information, the first device (identifier) ​​sends a ninth information to the second device (AIoT device), such as a Random Access Response or an acknowledgment indication (ACK), which includes the first identifier in the eighth information.

[0122] In some embodiments, the identification process may further include the following optional operations:

[0123] 414: After sending the ninth information, the first device (identifier) ​​starts a first timer, such as timer T1, to wait for the second device (AIoT device) to reply to the second device's information.

[0124] Operation 414 is an optional operation and is indicated by a dashed line in FIG4 .

[0125] Next, the recognition process also includes:

[0126] 415: The second device (AIoT device) verifies whether the first identifier in the received ninth information is consistent with the first identifier stored in the second device (AIoT device);

[0127] 416: When the verification result is consistent, the second device (AIoT device) sends the tenth information to the first device (identifier), and the second information at least includes the tenth information, and the tenth information at least includes the information of the second device.

[0128] For example, after receiving the ninth information, the second device (AIoT device) verifies whether the first identifier contained therein is consistent with the stored first identifier. If they are consistent, the tenth information is sent to the first device (identifier) ​​to indicate information of the second device (AIoT device), for example, the information of the second device includes at least one of the device identifier or device number of the second device, the device information of the second device, the associated item information of the second device, and the associated user information of the second device.

[0129] 417: The first device (identifier) ​​decodes the tenth information;

[0130] 418: When the decoding is successful, the first device (identifier) ​​performs a first process;

[0131] The first process includes at least one of the following processes:

[0132] The first device (identifier) ​​considers that the identification of the second device (AIoT device) is successful;

[0133] The first device (identifier) ​​stores the information of the second device (AIoT device) in the tenth information;

[0134] The first device (identifier) ​​reports the identification result of the second device (AIoT device) to the core network or network device;

[0135] The first device (identifier) ​​sends eleventh information to the second device, where the eleventh information is at least used to notify the second device that it has been successfully identified by the first device.

[0136] For example, if the first device (identifier) ​​decodes successfully, it is considered that the first device (identifier) ​​has successfully identified (inventoryed) the second device (AIoT device), and the first device (identifier) ​​with storage capability stores the second device (AIoT device) information in the tenth information. The first device (identifier) ​​optionally sends the eleventh information to the second device (AIoT device) to notify the second device (AIoT device) that the identification is successful. The second device (AIoT device) receives the eleventh information and updates the stored identification identifier to indicate that it has been successfully identified by the first device (identifier) ​​of the identification session process. The first device (identifier) ​​optionally reports the identification result of the second device (AIoT device), such as the information of the second device (AIoT device), to a high-level network node (core network or network device).

[0137] The identification process also includes:

[0138] 419: When the first timer times out or the decoding fails, the first device (identifier) ​​sends twelfth information to the second device (AIoT device), and the twelfth information is at least used to indicate a failure to receive the tenth information content, and / or the twelfth information includes a first identifier, and the first identifier includes at least a random number generated by the second device (AIoT device).

[0139] For example, if the first device (identifier) ​​fails to decode or the first timer times out, the twelfth information, such as NAK, is sent to the second device (AIoT device), which may include the first identifier. After the second device (AIoT device) receives the twelfth information, if it contains the first identifier and is consistent with the stored first identifier, it resends the tenth information to the first device (identifier), otherwise it waits for the next round of identification process.

[0140] In some embodiments, the identification process may further include:

[0141] 420: The core network or network device sends thirteenth information to the first device (identifier), where the thirteenth information is used to indicate data transmission between the first device (identifier) ​​and the second device (AIoT device).

[0142] 421: The first device (identifier) ​​and the second device (AIoT device) perform data transmission.

[0143] For example, the AIoT device-related signaling received by the first device (identifier) ​​from the core network or network device in operation 401 includes a data transmission instruction to the second device (AIoT device), such as read / write information.

[0144] In this case, operation 420 may be included in operation 401 and need not be performed separately.

[0145] For another example, after the first device (identifier) ​​reports the identification result of the second device (AIoT device) to the core network or network device, the core network or network device instructs the first device (identifier) ​​to transmit data with the second device (AIoT device), such as reading / writing information.

[0146] According to the data transmission indication, the first device (identifier) ​​and the second device (AIoT device) further perform data transmission or read-write interaction.

[0147] Next, the identification process may also include:

[0148] 422: The first device (identifier) ​​stores the data transmission result between the first device (identifier) ​​and the second device (AIoT device);

[0149] 423: The first device (identifier) ​​sends fourteenth information to the core network or network device. The fourteenth information at least includes the data transmission result between the first device (identifier) ​​and the second device (AIoT device).

[0150] For example, after completing data transmission with the second device (AIoT device), the first device (identifier) ​​with storage capability stores the read / write results and optionally reports the data transmission results to the second device (AIoT device) to a higher-level network node (core network or network device).

[0151] In some embodiments, after successfully identifying a second device (AIoT device), the first device (identifier) ​​can immediately report the identification result of the second device (AIoT device) to the core network or network device, such as the information of the second device and / or the first identifier related to the second device.

[0152] For example, after successfully identifying the second device (AIoT device), the first device (identifier) ​​sends the fifteenth information to the core network or network device, and the fifteenth information includes at least one information of the second device (AIoT device) and / or a first identifier related to the second device; for example, the first device (identifier) ​​reports the identification result of the second device (AIoT device), such as the information of the second device (AIoT device), to the high-level network node (core network or network device).

[0153] For example, one of the processes in operation 418 embodies the above-mentioned reporting process.

[0154] After one round of recognition is completed, a new round of recognition can be continued, as shown in FIG4 . The recognition process also includes:

[0155] 424: The first device (identifier) ​​resends the fourth message or a new third message to the second device (AIoT device) to initiate a new round of identification. A second device (AIoT device) that has already been successfully identified during this identification session may not participate in the new round of identification. The fourth message may indicate whether the successfully identified second device (AIoT device) wishes to participate in the new round of identification.

[0156] Then, operations 407 to 423 may be repeated until the second device (AIoT device) identification session is completed, for example, when there is no new second device (AIoT device) feedback information in this round, the entire identification session is considered completed.

[0157] In some embodiments, the identification results of all second devices (AIoT devices) may be summarized and reported after the entire identification process is completed, such as information of all successfully identified second devices and / or first identifiers related to the second devices.

[0158] As shown in FIG4 , the recognition process further includes:

[0159] 425: After determining that the identification session process for all second devices (AIoT devices) is completed, the first device (identifier) ​​summarizes the identification results of all second devices (AIoT devices) and sends the sixteenth information to the core network or the network device. The sixteenth information at least includes the summarized identification results of all second devices (AIoT devices).

[0160] For example, the first device (identifier) ​​determines that the second device (AIoT device) identification session is completed. For example, when there is no new second device (AIoT device) information feedback, the identification session is considered to be completed; the results of all second device (AIoT device) identifications are summarized and reported to the network node that triggers the identification (inventory) of the second device (AIoT device), for example, the first device (identifier) ​​sends the information of all successfully identified second devices (AIoT devices) and / or the first identifier related to the second device to the core network or network device.

[0161] In the above embodiment, each information sent by the first device (identifier) ​​or the second device (AIoT device) can be sent in the form of signaling, messages, or signals.

[0162] According to the above embodiment, an instruction signaling or signal from the network node is added before each operation of the second device (AIoT device), so that the second device (AIoT device) without an energy storage device can also use the signaling or signal of the network node to adjust and modify the stored information and feedback or send device-related information to the network node. Using the above process, the network can obtain the information of the second device (AIoT device) and then page the second device (AIoT device). The second device (AIoT device) can initiate a random access process to the network, thereby realizing data transmission between the network and the second device (AIoT device).

[0163] In addition, for the processes involving the new third information, fifth information, seventh information and seventeenth information in the above embodiments, the signaling messages can be adjusted based on different AIoT capabilities and application scenarios to reduce redundant signaling interactions.

[0164] In some embodiments, the identification method further comprises:

[0165] The first device (identifier) ​​updates and maintains the stored information of the first identifier and / or the second device (AIoT device) related to the second device (AIoT device), and / or

[0166] The first device (identifier) ​​reports the latest information of the first identifier and / or the second device (AIoT device) related to the second device (AIoT device) to the superior network node.

[0167] In some embodiments, the method further comprises:

[0168] For the second device (AIoT device) that has been successfully identified, the first device (identifier) ​​directly sends the first identifier to the second device (AIoT device) to start re-identification of the second device, that is, to start a new round of identification process; and / or,

[0169] For the second device (AIoT device) that has been successfully identified, the first device (identifier) ​​directly initiates a paging call to the second device (AIoT device) based on the information and / or the first identifier of the second device (AIoT device); and / or,

[0170] For the second device (AIoT device) that has been successfully identified, the first device (identifier) ​​directly transmits data with the second device (AIoT device) based on the information and / or the first identifier of the second device (AIoT device).

[0171] The first identifier is the latest first identifier related to the second device (AIoT device) stored by the first device (identifier) ​​or indicated by the upper network node of the first device (identifier).

[0172] The information of the second device (AIoT device) is the information of the second device (AIoT device) stored by the first device (identifier) ​​or indicated by the upper network node of the first device (identifier).

[0173] For example, when the first device (identifier) ​​initiates a new identification session for the second device (AIoT device) that has been successfully identified, it can skip operations 403 to 412 in Figure 4, and directly start re-identification of the second device that has been successfully identified by sending the ninth information containing the latest first identifier stored by the first device (identifier) ​​or indicated by the superior network node of the first device (identifier). The first device (identifier) ​​can optionally start a first timer, such as T1, to wait for the second device (AIoT device) to reply with device-related information. The second device (AIoT device) verifies whether the stored first identifier and the first identifier in the ninth information are consistent. If they are consistent, it continues to execute subsequent processes such as sending the tenth information. If the first device (identifier) ​​does not receive the tenth information sent by the second device (AIoT device) when the first timer times out or the decoding fails, it needs to fall back to the process of identification by means of the third information or the fourth information or the new third information, and clear the stored first identifier of the second device (AIoT device).

[0174] For example, when the first device (identifier) ​​initiates paging to a second device (AIoT device) that has been successfully identified, the paging can be initiated directly using the information of the second device (AIoT device) stored in the first device (identifier) ​​without re-identifying the second device (AIoT device). For example, the identification (such as ID) of the second device (AIoT device) is included in the paging message, and the second device (AIoT device) with the identification is paged.

[0175] For example, when the first device (identifier) ​​initiates a data transmission request to a second device (AIoT device) that has been successfully identified, it can directly enter the data transmission stage using the information of the second device (AIoT device) stored in the first device (identifier) ​​without re-identifying the second device (AIoT device). For example, it can use the stored first identifier to confirm with the second device (AIoT device) and instruct the second device (AIoT device) to send an uplink transmission, etc.

[0176] In this way, based on different AIoT capabilities and application scenarios, signaling messages can be adjusted to reduce redundant signaling interactions.

[0177] It is worth noting that the above is only a schematic illustration of the embodiments of the present application, and the present application is not limited thereto. For example, the execution order of the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced.

[0178] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0179] It can be seen from the above embodiments that the network device or intermediate node sends first information for identifying the AIoT device to the AIoT device, and receives second information sent based on the first information from the AIoT device. In this way, the network can obtain the information of the AIoT device and then page the AIoT device, and the AIoT device can initiate a random access process to the network, thereby realizing data transmission between the network and the AIoT device.

[0215] In some embodiments, the method further comprises:

[0216] When the location of the resource used to send the eighth information to the first device is reached, for example, when the value or count of the feedback resource location randomly generated or updated by the second device based on the fourth information or the new third information or the sixth information or the seventeenth information is 0, the second device generates and stores the new first identifier and / or sends the eighth information to the first device, and the eighth information at least includes the new first identifier.
