[0042] - Study whether and how reachability and paging apply to Ambient IoT Device (s) considering the Ambient IoT devices capability and characteristics, and if so, what are the impacts.
[0043] - Study how to identify Ambient IoT Device or group of devices and how to format the identifier.
[0044] Principles and implementations of the present disclosure will be described in detail below with reference to the figures.
[0045] FIG. 1 illustrates an example communication environment 100 in which example embodiments of the present disclosure can be implemented. As shown in the example architecture 100 of FIG. 1, there are a plurality of devices including an AIoT controller 110, a device implementing an Application Function (AF) 120 (also referred to as AF 120 for purpose of discussion) , a device implementing an AIoT device management function 130 (also referred to as AIoT device management function 130 or AIoT device management 130 for purpose of discussion) , an AIoT reader 140, an AIoT device 150, and a device implementing an AIoT policy management function 180 (also referred to as AIoT policy management function 180 or AIoT policy management 180 for purpose of discussion) .
[0046] The AIoT controller 110 may be a core network entity that enables AIoT scenarios. It may be a network function implemented in the core netwrok. In some embodiments, the AIoT controller 110 may be implemented at an existing core network entity or as a part of an existing netwrok function. Alternatively, it may be implemented as a new network function. It is to be understood that the above are discussed for purpose of illustration, rather than suggesting any limitations.
[0047] The AIoT controller 110 may work alongside core network functions, such as Application Function (AF) 120, AIoT device management function 130, AIoT reader 140 and / or the like.
[0048] The Application Function (AF) 120 may be a network service provider. For example, the AF 120 may be a functional device immediate response to changing conditions or requirements, such as adjusting irrigation schedules based on real time data.
[0049] The AIoT device management function 130 may be a combination of devices and functionalities implemented within the AIoT system for overseeing and controlling AIoT devices. For example, the AIoT device management function 130 may be a security enhancement module or an efficiency improvement module of a AIoT system.
[0050] The AIoT reader 140 may be a device that reads and interprets data gathered from the AIoT device 150. The AIoT reader 140 may extract meaningful information from the vast amount of data produced by the ambient environment, making it useful for various applications.
[0051] The AIoT device 150 may refer to an IoT device which is much smaller and cheaper compared to previous generations of IoT. The ultimate ambient IoT energy source is that from radio waves. Both Ambient IoT and Ambient computing rely upon energy harvesting as one of the key mechanisms for powering and enabling the technology. Energy harvesting, as it applies to Ambient IoT and Ambient Computing, is the harnessing of the power in ambient radio waves to power tiny computers. An ambient IoT device may have a new radio / air interface to a reader / node. The new radio interface may be frame based or non-frame based. Deploying ambient IoT service on existing system could reduce the operation cost and quickly commercialize the new service.
[0052] The AIoT policy management function 180 may be a device or a node or an entity that manage policies in the AIoT architecture / system. The policies may be dynamically changed or made by the AIoT policy management function 180, for example, based on load status, time variation, and other relevant factor (s) . The AIoT policy management function 180 may be for example collocated with policy control function (PCF) .
[0053] In some embodiments, the AIoT Controller 110 may be named as an AIoT Function or may be implemented associated with or together with the AIoT Management Function 130. In some example implementations, the AIoT device Management 130 may be collocated with User Data Management (UDM) .
[0054] It is to be understood that the number of devices and their connections shown in FIG. 1 are only for the purpose of illustration without suggesting any limitation. The communication environment 100 may include any suitable number of devices configured to implementing example embodiments of the present disclosure. Although not shown, it would be appreciated that one or more additional devices may be located in the communication environment 100.
[0055] The communications in the communication environment 100 may conform to any suitable standards including, but not limited to, Global System for Mobile Communications (GSM) , Long Term Evolution (LTE) , LTE-Evolution, LTE-Advanced (LTE-A) , New Radio (NR) , Wideband Code Division Multiple Access (WCDMA) , Code Division Multiple Access (CDMA) , GSM EDGE Radio Access Network (GERAN) , Machine Type Communication (MTC) and the like. The embodiments of the present disclosure may be performed according to any generation communication protocols either currently known or to be developed in the future. Examples of the communication protocols include, but not limited to, the first generation (1G) , the second generation (2G) , 2.5G, 2.75G, the third generation (3G) , the fourth generation (4G) , 4.5G, the fifth generation (5G) communication protocols, 5.5G, 5G-Advanced networks, or the sixth generation (6G) networks.
[0056] FIG. 2A illustrates a schematic diagram of an example connectivity topology of an AIoT device. In the communication environment 200A, a plurality of communication devices, including an AIoT device 150 and a network device 170, can communicate with each other. The AIoT device 150 may be the AIoT device 150 discussed with reference to FIG. 1.
[0057] In the example of FIG. 2A, the ambient IoT device 150 communicates bidirectionally with the network device 120. In the communication environment 100A, the network device 170 may be a base station. For example, the network device 170 may be outdoor, and the ambient IoT device 150 may be indoor.
[0058] The network device 170 may be a NG-RAN device. As used herein, the term "RAN" refers to a radio access network, a critical component of wireless communication systems such as LTE and 5G. The RAN connects devices, such as smartphones and IoT devices, to the core network, facilitating the transmission of data and control signals. “NG-RAN” , also known as the next generation RAN, is an important part of the 5G network architecture. In some embodiments of the present disclosure, the netwrok device 170 is sometimes referred to as a NG-RAN device.
[0059] FIG. 2B illustrates a schematic diagram of another example connectivity topology of an AIoT device. In the communication environment 200B, a plurality of communication devices, including the AIoT device 150 discussed with reference to FIG. 1, a network device 170 and an intermediate node 160, can communicate with each other.
[0060] In the example of FIG. 2B, the AIoT device 150 communicates bidirectionally with an intermediate node 160 between the ambient IoT device 150 and the network device 170. In the communication environment 200B, the network device 170 may be a base station serving an intermediate node 160. The intermediate node 160 may be a UE, a relay, an IAB node, a repeater, and the like which is capable of Ambient IoT. The intermediate node 160 may transfer Ambient IoT data and / or signaling between the ambient IoT device 150 and the network device 170, and a UE may act as an intermediate node 160 which is under the control of the network device 170. For example, the network device 170 may be outdoor, and the ambient IoT device 150 may be indoor.
[0061] It is to be understood that although illustrated as a network device, the network device 170 may be another device than a network device. Although illustrated as a terminal device, the intermediate node 160 may be a device other than a terminal device.
[0062] It is to be understood that the number of devices and their connections shown in FIG. 2A or 2B are only for the purpose of illustration without suggesting any limitation. The communication environment 200A or 200B may include any suitable number of devices configured to implementing example embodiments of the present disclosure. Although not shown, it would be appreciated that one or more additional devices may be located in the cell, and one or more additional cells may be deployed in the communication environment 200A or 200B.
[0063] In the following, for the purpose of illustration, some example embodiments are described with the intermediate node 160 operating as a UE which may be authorized to be an intermediate node, and the network device 170 operating as a base station. However, in some example embodiments, operations described in connection with a terminal device may be implemented at a network device or other device, and operations described in connection with a network device may be implemented at a terminal device or other device.
[0064] In some example embodiments, the AIoT device 150 may be a terminal device (e.g., UE) and the network device 170 may be a base station (e.g., gNB) . In this case, a link from the network device 170 to the AIoT device 150 may be referred to as a downlink (DL) , while a link from the AIoT device 150 to the network device 170 may be referred to as an uplink (UL) . In DL, the network device 170 is a transmitting (TX) device (or a transmitter) and the AIoT device 150 is a receiving (RX) device (or a receiver) . In UL, the AIoT device 150 is a TX device (or a transmitter) and the network device 170 is a RX device (or a receiver) .
[0065] Embodiments of the present disclosure are related to QoS control for an AIoT service, which is for example is associated with an inventory procedure or other procedures such as command, in a topology such as that discussed with reference to FIG. 2A. More details will be discussed below.
[0066] Reference is made to FIG. 3, which illustrates a signaling flow 300 of a process of AIoT QoS control in accordance with some embodiments of the present disclosure.. As shown in FIG. 3, the signaling flow 300 involves a first communication device 301, a second communication device 302, and a third communication device 303. In addition, the signaling flow 300 may further involve a fourth communication device 304 and a fifth communication device 305.
[0067] By referring to the embodiments of FIG. 1, the first communication device 301 may be implemented as the AIoT controller 110. The second communication device 302 may be implemented as the AIoT reader 140 or also referred to reader 140. The third communication device 303 may be implemented as the AF 120, the AIoT device management function 130, or the AIoT policy management function 180. The fourth communication device 304 may be implemented as the AF 120 and the fifth communication device 305 may be implemented as the AIoT device 150.
[0068] In the signaling flow 300, the fourth communication device 304 transmits (312) , to the first communication device 301, a first request for an ambient internet of things (AIoT) service associated with a first AIoT device. The AIoT service may be related to, for example, but not limited to, an inventory procedure, a command procedure, or other suitable procedure related to AIoT.
[0069] The first communication device 301 receive (313) the first request and transmits (316) , to the second communication device 302, a second request comprising a set of quality parameters for performing the AIoT service. The set of quality parameters may include the QoS parameters or may be also referred to as the QoS parameters in some cases.
[0070] The set of quality parameters may include a variety of parameters associated with QoS. For example, the set of quality parameters may be a maximum time duration for the AIoT service, a predetermined successful rate of the AIoT service, an AIoT device priority, and / or the like.
[0071] The maximum time duration for the AIoT service may be a maximum time duration for inventory. For example, after the reader 140 receives the Inventory Request, the reader 140 expects to send Inventory response before the max time duration time out. It restricts the maximum time duration for inventory to avoid a time duration that is too long, e.g. when an AIoT device cannot be read.
[0072] The predetermined successful rate of the AIoT service may be a guaranteed reading successful rate of inventorying an AIoT device group. It defines the lowest successful rate of reading AIoT devices in the group, when the reader 140 (also referred to as RAN reader 140) receives the Inventory Request including multiple AIoT devices in the group. It enforces the reader 140 to guarantee the successful rate of inventory.
[0073] The AIoT device priority may refer to a priority of the AIoT device 150 in the inventory group. When there are multiple devices in the group for inventory, the AF 120 may indicate the priority for different devices, when the reader 140 receives such information, it may prioritize the high-priority device for inventory.
[0074] In some embodiments, the first request may include, for example, but not limited to, an identification of the first AIoT device, a group identification for a plurality of AIoT devices comprising the first AIoT device, and / or other information. Likewise, the second request may have similar information or content as the first request. In some embodiments, the second request may include, for example, but not limited to, an identification of the first AIoT device, or a group identification for a plurality of AIoT devices comprising the first AIoT device, and / or other information.
[0075] The second communication device 302 receives (318) , from the first communication device, the second request. Then, the second communication device 302 transmits (319) , to the fifth communication device 305, e.g., the first AIoT device (for instance, the AIoT device 150) , a fifth request for performing the AIoT service based on the set of quality parameters.
[0076] In some cases where the set of quality parameters comprises an AIoT device priority, the second communication device 302 transmit the fifth request when a certain condition is met. For example, in response to determining a priory of the first AIoT device is higher than or equal to the AIoT device priority, the second communication device 302 transmits (319) the fifth request for performing the AIoT service to the fifth communication device 305 (e.g., the AIoT device 150) .
[0077] Upon receiving (320) the fifth request, the fifth communication device 305 may transmit (321) a response to the second communication device 302 in some embodiments. The second communication device 302 receives (322) the response from the fifth communication device 305 accordingly. In predefined or predetermined time duration, the second communication device 302 may receive one or more responses from various AIoT devices, or receive no response at all. In some embodiments, the set of quality parameters comprises a maximum time duration for the AIoT service. In this case, the second communication device 302 may transmit (324) , to the first communication device 301, a response to the second request indicating a list of AIoT devices with which the AIoT service is performed within the maximum time duration.
[0078] Thus, the first communication device 301, may receive (326) the response to the second request. Based on the received response, the first communication device 301 may determine if a response to the fifth request is received from the first AIoT device within the maximum time duration. If so, it may determine the first AIoT device belongs to the list of AIoT devices.
[0079] In some embodiments, the set of quality parameters may include a predetermined successful rate of the AIoT service, and in this case, and the second communication device 302 may transmit (324) , to the first communication device 301, a response to the second request indicating a list of AIoT devices with which a successful rate of the AIoT service is higher than or equal to the predetermined successful rate. Upon receiving (326) such a response, the first communication device 301 may have the knowledge of the list of AIoT devices with high successful rate.
[0080] Then, the first communication device 301 may transmit (328) a message to the fourth commutation device 304 (e.g., the AF 120) as a response to the first request. Upon receiving (330) the response message, the fourth communication device 304 may know that the requested AIoT service is performed.
[0081] It is to be understood that that the operations at 314, 315, and 321 to 330 are optional. The protection scope of the present disclosure is not limited to this.
[0082] In some embodiments, the third communication device 303, which may be for example, the AF 120, the AIoT device management function 130 or AIoT policy management function 180, may transmit (314) the set of quality parameters to the first communication device 301. Thus, the first communication device 301 may obtain the set of quality parameters by receiving (315) the set of quality parameters from the third communication device 303. It is to be understood that the above examples of the third communication device 303 are illustrated for discussion, rather than suggesting any limitations. The third communication device 303 may be implemented as other suitable devices or entities.
[0083] In some embodiments, the third communication device 303 may be implemented as a first network device implementing an Application Function (AF) , for example, the AF 120. That is, the third communication device 303 is collocated with the fourth communication device 304 or is the fourth communication device 304. In this case, both the third communication device 303 and the fourth communication device 304 are implemented as the AF 120. Thus, the set of quality parameters may be included in the first request received at 313 or included in a different message or signaling transmitted (314) from the communication device 304 to the first communication device 301.
[0084] Alternatively, the third communication device 303 may be implemented as a second network device implementing an AIoT device management function, e.g., the AIoT device management function 130. In this case, the first communication device 301 may transmit, to the third communication device 303 (e.g., the AIoT device management function 130) , a third request for subscription information of the first AIoT device. The third communication device 303 after receiving the third request, may transmit (314) the subscription information indicating the set of quality parameters to the first communication device 301. Thus, the first communication device 301 may receive (315) the set of quality parameters from the third communication device 303 (e.g., the AIoT device management function 130) .
[0085] In addition, in some embodiments where the third communication device 303 is implemented as a second network device implementing an AIoT device management function, e.g., the AIoT device management function 130, the third communication device 303 may transmit, to the first communication device 301, updated subscription information for updating the set of quality parameters. Correspondingly, the first communication 301 may receive updated subscription information from the third communication device 303, and update the set of quality parameters based on the updated subscription information.
[0086] As a further alternative to the AF 120 and the AIoT device management function 130, the third communication device 303 may be implemented as a third network device implementing an AIoT policy management function, e.g., the AIoT policy management function 180. In this case, the first communication device 301 may transmit, to the third communication device 303 (e.g., the AIoT policy management function 180) , a fourth request for policy information for the AIoT service. The third communication device 303, after receiving the fourth request, may transmit (314) the policy information indicating the set of quality parameters to the first communication device 301. Thus, the first communication device 301 may receive (315) the set of quality parameters from the third communication device 303 (e.g., the AIoT policy management function 180) .
[0087] In the embodiments of the present disclosure, AIoT QoS control of inventory in the topology of FIG. 2A may be provided in core network and RAN as following. Specifically, in some embodiments, the AF 120 provides quality parameters (also referred to as QoS parameters for purpose of discussion) for an AIoT inventory operation. The QoS parameters may include a maximum time duration for inventory, a guaranteed reading-device successful rate of inventorying an AIoT device group, an AIoT device priority in the inventory group, and / or the like. This will be discussed in detail with reference to FIG. 4.
[0088] Alternatively, the AIoT device management 130 may provide AIoT device subscription for QoS, which includes an AIoT device priority in the AIoT service. This will be discussed in detail with reference to FIG. 5.
[0089] As a further alternative, the AIoT policy Management 180 may consider AF priority and AIoT device / group priority in the AIoT service, and may send the QoS parameter to the reader 140 via the AIoT controller 110. This will be discussed in detail with reference to FIG. 6.
[0090] In addition, a QoS control parameters modification procedure with AIoT device subscription change is proposed in some embodiments of the present disclosure, which will be discussed in detail with reference to FIG. 7.
[0091] FIG. 4 illustrates a signaling flow 400 of an example process of AIoT QoS control in accordance with some embodiments of the present disclosure. For purpose of discussion, the embodiments of FIG. 4 will be discussed with respect to FIG. 1. As shown in FIG. 4, the signaling flow 400 involves the AIoT controller 110, the AF 120, the AIoT reader 140, and the AIoT device 150.

The AF 120 may be considered as an implementation of the third communication device 303 and the fourth communication device 304 of FIG. 3. That is, in this case, the third communication device 303 and the fourth communication device 304 are the same or implemented at the same entity. The AIoT device 150 may be considered as an implementation of the fifth communication device 305 of FIG. 3.
[0093] In the embodiments of FIG. 4, the QoS parameter is indicated by the AF 120. As shown in FIG. 4, at 411, the AF 120 may transmit an inventory request, e.g., an Inventory Request (Device ID or Group ID, QoS parameter) , to the AIoT controller 110.
[0094] At 412, the AIoT controller 110 may transmit an inventory request, e.g., Inventory Request (Device ID or Group ID, QoS parameter) to the reader 140.
[0095] The reader 140 may thus know the QoS parameter based on the received inventory request. In some embodiments, the QoS parameter includes the AIoT device priority, which may be indicated by the AF 120 for different AIoT devices. The reader 140 may prioritize the AIoT devices for inventory based on the information about AIoT device priority. In an example, assuming that the AIoT device 150 has a higher priority. Then, at 413, the reader 140 may transmit an inventory request, e.g., the Inventory Request (Device ID or Group ID) to the AIoT device 150 whose priority is relatively high.
[0096] At 414, the AIoT device 150 may transmit an inventory response, e.g., the Inventory Response (Device ID) , to the reader 140.
[0097] The reader 140 may monitor inventory responses from one or more AIoT devices during a maximum time duration for inventory, which may be indicated in the QoS parameters to avoid a time duration that is too long, e.g. when an AIoT device cannot be read. Then, at 415, the reader 140 may transmit an inventory response, e.g., the Inventory Response (Device ID, Reader ID) , to the AIoT controller 110.
[0098] At 416, the AIoT controller 110 may transmit an inventory response, e.g., the Inventory Response (Device ID, Reader ID) , to the AF 120.

For purpose of discussion, the embodiments of FIG. 5 will be discussed with respect to FIG. 1. As shown in FIG. 5, the signaling flow 500 involves the AIoT controller 110, the AF 120, the AIoT device management 130, the AIoT reader 140, and the AIoT device 150.
[0100] The AIoT controller 110 may be considered as an implementation of the first communication device 301 of FIG. 3.

[0102] As shown in FIG. 5, at 511, the AF 120 may transmit an inventory request, e.g., an Inventory Request (Device ID or Group ID) , to the AIoT controller 110.
[0103] At 511a, the AIoT controller 110 may send a device subscription request, e.g., the Device subscription request (Device ID or Group ID) to the AIoT device management 130 to request the device subscription, which may include Device ID or Group ID received from the AF 120.
[0104] At 511b, the AIoT device management 130 may send the device or group subscription to the AIoT controller 110. For example, the AIoT device management 130 may send a device subscription response, e.g. the Device subscription response (Device ID or Group ID, Device or group subscription including QoS parameter) , which may include the QoS parameter for the device or group.
[0105] It is to be understood that steps 511a and 511b are both optional. Because the AIoT controller 110 may store QoS parameter (s) received before and may check before request for subscription information to the AIoT device management 130. The QoS parameter (s) may be stored locally at the AIoT controller 110 and may be updated in response to subscription change or update, which will be discussed with reference to FIG. 7.
[0106] At 512, the AIoT controller 110 may transmit an inventory request, e.g., Inventory Request (Device ID or Group ID, QoS parameter) to the reader 140.
[0107] The reader 140 may thus know the QoS parameter based on the received inventory request. In some embodiments, the QoS parameter includes the AIoT device priority, which may be indicated by the AF 120 for different AIoT devices. The reader 140 may prioritize the AIoT devices for inventory based on the information about AIoT device priority. In an example, assuming that the AIoT device 150 has a higher priority. Then, at 513, the reader 140 may transmit an inventory request, e.g., the Inventory Request (Device ID or Group ID) to the AIoT device 150 whose priority is relatively high.
[0108] At 514, the AIoT device 150 may transmit an inventory response, e.g., the Inventory Response (Device ID) , to the reader 140.
[0109] The reader 140 may monitor inventory responses from one or more AIoT devices during a maximum time duration for inventory, which may be indicated in the QoS parameters to avoid a time duration that is too long, e.g. when an AIoT device cannot be read. Then, at 515, the reader 140 may transmit an inventory response, e.g., the Inventory Response (Device ID, Reader ID) , to the AIoT controller 110.
[0110] At 516, the AIoT controller 110 may transmit an inventory response, e.g., the Inventory Response (Device ID, Reader ID) , to the AF 120.
[0111] QoS parameter in AIoT device / group subscription may include AIoT device / group priority, which indicates the AIoT device / group priority in the AIoT network and is considered in the Reader for inventory with different AIoT devices or groups.

[0116] At 611a, the AIoT controller 110 may send a AIoT policy request (e.g., AIoT policy request (Device ID or Group ID, AF ID or IP Address) ) to the AIoT policy management 180 to request the AIoT policy for this Inventory, which may include Device ID or Group ID received from AF, and the AF ID or IP address.
[0117] At 611b, based on the receiving device ID, device group ID and AF ID / IP Address, the AIoT policy management 180 may consider the priority of AF, AIoT device or group, and send an AIoT policy response, which may include the QoS parameter for the device or group. The AIoT policy response may be for example in the form of AIoT policy response (Device ID or Group ID, Device or group policy including QoS parameter.

The reader 140 may prioritize the AIoT devices for inventory based on the information about AIoT device priority. In an example, assuming that the AIoT device 150 has a higher priority.
