Description

AMBIENT IOT SYSTEM TECHNICAL FIELD
The present disclosure relates to the field of communication systems, and more particularly, to an Ambient Internet of Things (AIoT) system.
BACKGROUND
Ambient Internet of Things (AIoT) devices are ambient power-enabled IoT devices, primarily powered through energy harvesting. The AIoT devices may either operate without batteries or possess limited energy storage capabilities, e.g., using capacitors. Distinct from other devices like narrowband-internet of things (NB-IoT) , cell phones, and 5G residential gateways (RGs) , AIoT devices have unique characteristics. One of the characteristics for the AIoT devices is reliance on energy harvesting. The AIoT devices are battery-less and come with limited energy storage capabilities. In other words, its uptime is very limited either powered by harvested energy or powered by some prolonged communications time or up time by on-device limited energy storage. This energy constraint only allows for a narrow time window in which the AIoT devices can communicate with a fifth generation (5G) system. Based on these limitations, it is imperative to design a communication protocol stack that is not only lightweight, but also ensure rapid communication establishment, minimizes transactions, optimizes energy efficiency, and accelerates communication initiation. However, current technical solutions do not provide such a dedicated AIoT service function tailored to address unique requirements by the AIoT device. Further, current 5G systems lack the architecture and protocol stack for the AIoT devices to facilitate such communications.
Therefore, there is a need for an AIoT system, which can address the issues in the prior art and other issues.

DETAILED DESCRIPTION OF EMBODIMENTS
Embodiments of the present disclosure are described in detail with the technical matters, structural features, achieved objects, and effects with reference to the accompanying drawings as follows. Specifically, the terminologies in the embodiments of the present disclosure are merely for describing the purpose of the certain embodiment, but not to limit the disclosure.
For clarify, throughout the present disclosure, the terms, “AIoT tag” and “AIoT device” and other similar terms are interchangeable and bear no difference in meaning. The terms, “Ambient IoT node” , “Ambient IoT reader” , “AIoT node” , “AIoT reader” , simply “reader” and other similar terms are interchangeable and bear no difference in meaning. The terms, “AIoT Base Station” , “Base station with AIoT capabilities” , “Ambient IoT base station” , “Base station with Ambient IoT capabilities” and other similar terms are interchangeable and bear no difference in meaning in the present disclosure. The terms, “network element” and “network node” and other similar terms are interchangeable and bear no difference in meaning. The terms, “standalone” and “independent” and other similar terms are interchangeable and bear no difference in meaning.
In some embodiments, the term “/” can be interpreted to indicate “and/or. ” The term “configured” can refer to “pre-configured” and “network configured” . The term “pre-defined” or “pre-defined rules” in the present disclosure may be achieved by pre-storing corresponding codes, tables, or other manners for indicating relevant information in devices (e.g., including an AIoT tag/tag and a network device) . The specific implementation is not limited in the present disclosure. For example, “pre-defined” may refer to those defined in a protocol. It is also to be understood that in the disclosure, “protocol” may refer to a standard protocol in the field of communication, which may include, for example, an Long Term Evolution (LTE) protocol, new radio (NR) protocol and relevant protocol applied in the future communication system, which is not limited in the present disclosure.
Some embodiments of the present disclosure provide an Ambient Internet of Things (AIoT) system, including an AIoT service function (ASF) configured to facilitate an AIoT service delivery via a non-access stratum (NAS) signaling. This can address issues in the prior art and other issues, provide efficient and lightweight architecture and communication, ensure rapid communication establishment, reduce transactions, improve energy efficiency, and/or accelerate communication initiation.
In some embodiments, an AIoT Service over NAS architecture, protocol stacks, and a pub/sub architecture-based deployment scenario are disclosed. When communication originates from an AIoT tag (e.g., in certain cases where the AIoT tag has NAS capabilities) or originates from an AIoT Reader (e.g., in RICO mode, that is Reactive Interactive Connection Only, or Reader Initiated Connection Only) , data or information elements are transmitted via uplink NAS transport. Conversely, for communications, terminates at the AIoT tag (e.g., in certain cases where the AIoT tag has NAS capabilities) or at the AIoT Reader, delivery of data or information elements occurs through N1/N2 Messages. This process negates the necessity to establish a PDU session, and there is no requirement for involvement from Session Management Function (SMF) and User Plane Function (UPF) . This approach considerably diminishes the protocol stack’s complexity.
Notably, there is no need for Non-Access-Stratum Session Management (NAS-SM) layer in this configuration. Instead, a streamlined AIoT Service is efficiently positioned to function on top of Non-Access-Stratum Mobility Management (NAS-MM) layer directly. NAS-SM: it supports the handling of Session Management between the UE and the SMF. It supports user plane PDU Session Establishment, modification and release. It is transferred via the AMF, and transparent to the AMF. NAS-MM: it supports registration management functionality, connection management functionality and user plane connection activation and deactivation. It is also responsible of ciphering and integrity protection of NAS signalling.
FIG. 1A illuatrates an Ambient Internet of Things (AIoT) system including an AIoT service function (ASF) using reference point representation configured to implement some embodiments presented herein. FIG. 1B illuatrates an AIoT system including an ASF using service-based interface configured to implement some embodiments presented herein. In this examplary architecture as illustrated in FIG. 1A and FIG. 1B, the conventional SMF and UPF are replaced by a simplified network function such as AIoT Service Function (ASF) . The ASF facilitates AIoT service delivery via NAS signaling without the need to establish a Protocol Data Unit (PDU) session.
In some embodiments, the ASF is responsible for at least one of the following responsibilities: an AIoT service activation and/or deactivation, an AIoT device state management, an AIoT tag management, an AIoT service management, relaying one or more information elements or data from one or more AIoT tags and/or an AIoT reader to one or more AIoT service providers, an application server, or an application function (AF) , handling AIoT service charges (such as relevant AIoT service charging aspects) , relaying the one or more information elements or the data from the one or more AIoT service providers, the application server, or the AF to the AIoT reader and/or the one or more AIoT tags (toward the AIoT reader and eventually to AIoT tags) , AIoT service charges, and interaction with an assess and mobility management function (AMF) via an interface in reference point representation (tentatively referred to as N11x) or service-based interface (tentatively referred to as Nasf) , a unified data management (UDM) via an  interface in reference point representation (tentatively referred to as N8a) or service-based interfaces Nudm and a servcie-based interface tentatively referred to as Nasf, and the one or more AIoT service providers for one or more notification procedures when the AIoT tag is unavailable for information transfer. In some examples, the AIoT device state management includes temporary disable/enable, permanently disable, power-off, dormant, sleep, active, and/or charging/energy collecting/energy harvesting, etc. In some examples, The AS or AF may be a 3rd party AS or a 3rd party AF.
It should be noted that the reference point representation or service-based representation of the interfaces N8a, N11x, Nasf are placeholders for the final names that will be adopted following standardization.
In some embodiments, the AIoT system includes the AMF. And, in addition to the existing funcitonalities currently defined in relevat 3GPP specifications, the AMF is responsible for at least one of the following new functionalities: an ASF selection, an AIoT tag registration, reachability management, and/or mobility management, an access authentication and/or authorization, providing transport for one or more AIoT service information elements between the AIoT reader and the ASF, and relaying the one or more information elements or the data to and/or from the ASF.
In some examples, AIoT Service Function (ASF) interacts with AMF to support bidirectional Ambient IoT communications over NAS signaling in 5G system. When the AIoT Service Function triggers a service request, the AIoT service function allows AMF to forward uplink data originated from the AIoT tag or the AIoT reader, and further forward them to AIoT AF and AS.
In some embodiments, the AIoT system further includes an AIoT AF and/or an AIoT AS, the ASF allows the AIoT AF and/or the AIoT AS to issue one or more commands to the AIoT reader and/or the one or more AIoT tags to support one or more AIoT services. For examples, the AIoT service function allows AIoT AF and AS to issue commands to the AIoT reader or AIoT tag to support AIoT tag disabling, shutdown, suspend, energy harvesting, energy indication, as well as various AIoT services, such as inventory, sensor, positioning, command/actuator, etc.
In some embodiments, the AIoT system further includes the UDM, and the UDM is responsible for AIoT service subscription data. In details, in some examples, the ASF is connected to the UDM through a service-based interface to offer 5G AIoT services to 5G subscribers. Table 1 illustrates a list of Ambient IoT service subscription data in the UDM.
Table 1: Ambient IoT Service Subscription Data

The ASF supports at least one of following service operations: an activate operation, a deactivate operation, an AIoT uplink data operation, and/or an AIoT command operation. In some examples, the ASF supports one or more service operations as illustrated in Table 2.

FIG. 2 illustrates that, in some examples, an AIoT Base Station/gNB may include a module, e.g., AIoT Reader, designed to transmit a radio wave to activate AIoT tags, to support communication protocols ensuring interaction between the AIoT Base Station/gNB and AIoT tag, and to handle relevant 5G Ambient IoT procedures through N1 and N2 interfaces. The radio wave may take the form of a Carrier Wave to provide carrier frequency for backscattering communications between the Ambient IoT devcie and the AIoT Reader. The radio wave can also take the form of a type of Continuous Wave to provide energy harvesting source for the Ambient IoT devices. Alternatively, the radio wave could be a cominbation of Carrier Wave and Continuous Wave to provide both carrier frequency and energy harvesting source.
Alternatively, an external radio wave generator might be outside of the AIoT Base Station/gNB. The Radio Wave generator operates independently by sending carrier wave or continuous wave for tag performing backscattering communications/energy harvesting or under the control of the AIoT Base Station/gNB via a defined communications interface to transmit carrier wave or continuous wave to allow AIoT device to perform backscattering communicaitons/energy harvesting.
In some embodiments, the one or more AIoT tags with the one or more NAS capabilities are configured to perform at least one of following signaling procedures: a registration request procedure, a service request procedure, a message transfer service procedure, and a paging procedure.
In details, in some examples, when the AIoT tag accumulates sufficient energy either from the reader’s radio wave or periodic energy transmissions, it becomes active. For AIoT tags with NAS signaling capabilities, the AIoT tag may initiate registration request, service request, and other signaling procedures. These messages are conveyed to the AMF via the AIoT Base Station/gNB or simply the AIoT Reader using UL NAS Transport. The AMF then forwards these messages and the Ambient IoT identities to the AIoT Service Function (ASF) through the N11x/Nasf interface.
In details, in some examples, the ASF might invoke Namf_Communication_N1N2Message Transfer service to send an acknowledgment message to the AMF.
In details, in some examples, for the Ambient IoT device terminated communications, a specific Ambient IoT paging procedure is required. Once the AIoT tag is located, the Namf_communicaiton_N1N2Message delivers the AIoT service data to the AIoT tag using NAS signaling.
FIG. 3 illustrates an AIoT system including protocol stacks for one or more AIoT tags/devices with one or more NAS capabilities configured to implement some embodiments presented herein. In some embodiments, the AIoT system further includes protocol stacks for the one or more AIoT tags with the one or more NAS capabilities. FIG. 3 illustrates that protocol stacks for AIoT device with NAS capabilities in the presence of ASF.
FIG. 4 illustrates an AIoT system including an architecture for one or more AIoT tag/device without NAS capabilities configured to implement some embodiments presented herein. In some embodiments, the AIoT system further includes the one or more AIoT tags without NAS capabilities. FIG. 4 illustrates that architecture for AIoT device without NAS capabilities in the presence of ASF. In details, FIG. 4 illustrates that, in some examples, the AIoT tag does NOT have NAS signaling capabilities. The AIoT Reader residing on the AIoT Base Station/gNB or the AIoT Base Station/gNB performs NAS signaling functions on behalf of the AIoT tag. In some examples, when the AIoT tag accumulates sufficient energy, either from the reader's radio wave or through periodic energy transmissions, it becomes activated.
In some embodiments, the one or more AIoT tags without the NAS capabilities are configured to perform at least one of following signaling procedures: a registration request procedure, a service request procedure, a message transfer service procedure, and a paging procedure.
In some examples, procedures for AIoT device without NAS capabilities in the presence of ASF are disclosed. In some examples, for AIoT tags without NAS signaling capabilities, for AIoT tag/device-originated communications, upon the AIoT tag/device request, the AIoT reader or the AIoT Base Station/gNB initiates registration, service requests, and other signaling procedures on the tag's behalf. The AIoT reader or the AIoT Base Station/gNB utilizes an uplinl (UL) NAS Transport to transmit data collected from individual or grouped tags to the AMF. Subsequently, the AMF forwards the messages and AIoT tag identities to the AIoT Service Function (ASF) via the N11x/Nasf interface. In some examples, the ASF may employ the Namf_Communication_N1N2Message Transfer service to send an acknowledgment message back to the AMF. In some examples, the ASF may employ the Namf_Communication_N1N2Message Transfer service to send an acknowledgment message back to the AMF.
FIG. 5 illustrates an AIoT system including protocol stacks for one or more AIoT tags/devices without NAS capabilities configured to implement some embodiments presented herein. In some embodiments, the AIoT system further includes protocol stacks for the one or  more AIoT tags without the NAS capabilities. In other words, protocol stacks for AIoT device without NAS capabilities in the presence of ASF is disclosed.
In some examples, in the protocol stack, the Tag Service Layer (or other similar name/term, e.g., Data Service Layer, AIoT Tag Service Layer, AIoT Service Layer, or simply AIoT Layer) is responsible for handling the information defined by Ambient IoT service provider, or Ambient IoT network operator, or Ambient IoT device manufacture, or the end user. In some examples, the Tag Service Layer (TSL) could just provide a response to report its EPC (Electronic Product Code) code when the reader requests to perform such an operation, and the reader could further extract the corresponding information from the tagged object once activated. In some examples, the TSL layer could be responsible for interpretating the commands issued by the reader, or by the AIoT Application Server.
In some embodiments, the AIoT system further includes a tag service layer (TSL) , and when the one or more AIoT tags is requested to provide information to the AIoT reader, the TSL issues one or more commands to retrieve the information form the one or more AIoT tags.
In some examples, when an AIoT tag is interrogated to give information to the requested AIoT reader. The Tag Service Layer (TSL) may issue commands to retrieve the requested information form the storage of the AIoT tag, to request lower layers to encode the information by using proper encoding format, to request lower layers to transmit the request information in proper Radio Frequency (RF) signal formats.
In FIG. 5, in some examples, a simplified protocol stack can also help establish connections and exchange data quickly and efficiently. Because the AIoT tag power is limited, such a protocol stack can quickly complete the connection and exchange data quickly and efficiently.
FIG. 6 illustrates an AIoT system including a pub/sub architecture-based deployment for ASF configured to implement some embodiments presented herein. In some embodments, the AIoT service subscription data in the UDM is configured to choose a serving ASF for the one or more AIoT tags.
In some examples, given the vast presence of potentially millions of AIoT tags in field deployment, a flexible Publisher/Subscriber (Pub/Sub) system can be implemented as one possible embodiment to support scalability. In FIG. 6, AIoT tags T2 and T6 act as publishers and send messages related to both Topic 1 and Topic 2. Depending on the configuration in the Tag subscription profile in the UDM, AIoT Service Subscription data is used to choose the serving ASF for an AIoT tag or a group of AIoT tags.
In some examples, messages published by T2 are directed to ASF1. In some examples, messages published by T6 are directed to ASF2. In some examples, AIoT AS/AF1 subscribes to both Topic 1 and Topic 2, specifically from ASF1. As a result, AIoT service AS/AF1 receives messages: M1, M2, M3, M4, and M5. AIoT Service AS/AF2, on the other hand, subscribes to  Topic 2 from ASF1 and Topic 1 from ASF2. Consequently, it receives messages: M3, M4, M5, M6, and M7.
In the above some embodiments, an AIoT Service over NAS architecture and protocol stack are presented. When communication originates from the AIoT tag or originates from the AIoT Reader, or AIoT Base Station/gNB (e.g., in RICO mode) , the data or information elements are transmitted via Uplink NAS transport. Conversely, for communications terminates at the AIoT tag or at the AIoT Reader, or the AIoT Base Station/gNB, the delivery of data or information elements occurs through the NAS N1N2 Messages. This process negates the necessity to establish a PDU session, and there is no requirement for the involvement of SMF and UPF. This approach considerably diminishes the protocol stack’s complexity. Notably, there is no need for the NAS-SM layer in this configuration. Instead, a streamlined AIoT Service is efficiently positioned to function on top of the NAS-MM layer directly.
In summary, in some embodiments, exemplary lightweight architecture and protocol stacks for Ambient IoT service may include at least one of following benefits.
Scalability: the architecture and protocol stacks are scalable and can efficiently manage a large number of AIT devices in the network without straining system resources.
Reduced latency: the streamlined protocol and architecture can result in faster data transmission and processing, minimizing the lag time to allow the AIoT tag to complete information exchange and transactions in the limited energy storage time.
Higher reliability: fewer components and complexity can mean fewer points of failure, leading to a more reliable system.
Cost Efficiency: Lightweight architectures requires less processing power and storage, which results in cost savings on AIoT tags as well.
Easier Integration: integrating the AIoT devices into other systems or applications can be more straightforward.
Adaptability: the introduction of a dedicated AIoT service function NF means there is enough room to support further evolution of this server to cater to evolving requirements or emerging standards.
Lower maintenance: easier and less frequency maintenance, resulting in longer operational life and less downtime.
Commercial interests for some embodiments are as follows. 1. Solve issues in the prior art and other issues. 2. Provide efficient and lightweight architecture and communication, ensure rapid communication establishment, reduce transactions, improve energy efficiency, and/or accelerate communication initiation. 3. Some embodiments of the present disclosure can be used in many applications. Some embodiments of the present disclosure are used by chipset vendors, video system development vendors, automakers including cars, trains, trucks, buses, bicycles, moto-bikes, helmets, and etc., drones (unmanned aerial vehicles) , smartphone makers,  communication devices for public safety use, AR/VR/MR device maker for example gaming, conference/seminar, education purposes. Some embodiments of the present disclosure are a combination of “techniques/processes” that can be adopted in video standards to create an end product. Some embodiments of the present disclosure propose technical mechanisms. The at least one proposed solution, method, system, and apparatus of some embodiments of the present disclosure may be used for current and/or new/future standards regarding communication systems. Compatible products follow at least one proposed solution, method, system, and apparatus of some embodiments of the present disclosure. The proposed solution, method, system, and apparatus are widely used in a communication system. With the implementation of the at least one proposed solution, method, system, and apparatus of some embodiments of the present disclosure, at least one modification/improvement to methods and apparatus of energy-related based routing selection are considered for standardizing.

The computing device 1100 can execute program code that configures the processor 1112 to perform one or more of the operations described above with respect to some embodiments illustrated in FIG. 1 to FIG. 6. The program code may be resident in the memory 1114 or any suitable computer-readable medium and may be executed by the processor 1112 or any other suitable processor.
The computing device 1100 can also include at least one network interface device 1124. The network interface device 1124 can include any device or group of devices suitable for establishing a wired or wireless data connection to one or more data networks 1128. Non limiting examples of the network interface device 1124 include an Ethernet network adapter, a modem, and/or the like. The computing device 1100 can transmit messages as electronic or optical signals via the network interface device 1124.
FIG. 8 is a block diagram of an example of a communication system 1200 according to an embodiment of the present disclosure. Embodiments described herein may be implemented into the communication system 1200 using any suitably configured hardware and/or software. FIG. 8 illustrates the communication system 1200 including a radio frequency (RF) circuitry 1210, a baseband circuitry 1220, an application circuitry 1230, a memory/storage 1240, a display 1250, a camera 1260, a sensor 1270, and an input/output (I/O) interface 1280, coupled with each other at least as illustrated.
The application circuitry 1230 may include a circuitry such as, but not limited to, one or more single-core or multi-core processors. The processors may include any combination of general-purpose processors and dedicated processors, such as graphics processors, application processors. The processors may be coupled with the memory/storage and configured to execute instructions stored in the memory/storage to enable various applications and/or operating systems running on the system. The communication system 1200 can execute program code that configures the application circuitry 1230 to perform one or more of the operations described above with  respect to FIG. 1 to FIG. 6. The program code may be resident in the application circuitry 1230 or any suitable computer-readable medium and may be executed by the application circuitry 1230 or any other suitable processor.
