Description

Wireless communication methods Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a wireless communication method and a wireless communication device. Background Technology

[0002] In recent years, the Internet of Things (IoT) has received considerable attention in the field of wireless communication. With the continuous development of communication systems, IoT terminals will be applied to various fields, including homes, industry, agriculture, and healthcare. To enable large-scale deployment of IoT terminals in different scenarios, reducing their size, complexity, and power consumption has become crucial.

[0003] Traditional IoT devices, such as Narrowband IoT (NB-IoT) terminals, Machine Type Communications (MTC) terminals, and Reduced Capability User Equipment (RedCap UE), all require batteries that must be replaced or recharged periodically. With the surge in the number of IoT terminals, using existing systems will significantly increase power supply and labor costs. Furthermore, traditional terminals are unsuitable for extreme environments (such as high temperature and high pressure). Ambient IoT (AIoT) terminals, on the other hand, primarily utilize external environmental factors (such as light, radio waves, motion, and heat) for energy, requiring no batteries or only low-energy storage capacitors. They eliminate the need for manual battery replacement or recharging, effectively avoiding the problems of existing IoT systems. Compared to NB-IoT, MTC, and RedCap terminals, AIoT terminals are less complex, consume less power (microwatts compared to milliwatts for NB-IoT), and are less expensive. As AIoT terminals are a new type of terminal, there is currently no definitive system solution.

[0004] The work on AIoT-related technical standards is still in its early stages; it's a research project currently under discussion, and there are no directly related standard protocols yet. However, AIoT standards should be based on the 3rd Generation Partnership Project (3GPP) 5G mobile communication system standard architecture, including the introduction of new technologies and the enhancement of existing technologies.

[0005] Services related to AIoT terminals are called AIoT services. Due to the special nature of AIoT terminals, the characteristics of these services and their mobile communication requirements differ significantly from existing services. 3GPP completed the application scenario and requirement study in Release 18, and the System Architecture (SA) working group and the Radio Access Network (RAN) working group are currently conducting related technical solution research and standardization work in Release 19.

[0006] RAN2 needs to study and determine which functions are required by the Ambient IoT (AIoT) compact protocol stack and lightweight signaling procedures to support device-initiated, device-termination-triggered (DO-DTT), and device-termination (DT) data transmissions, and study these functions.

[0007] RAN3 requires research into: device context management, data transmission, and identifying potential solutions that are not affected by standards or have only minor standard-specification impacts for locating IoT devices in the environment, such as reusing existing user location reports or for transmitting location information to the core network. Technical issues:

[0008] Question 1: Protocol stack architecture, operation commands, and data transmission methods related to AIoT services.

[0009] For existing 5G mobile communication systems, AIoT services represent a new type of service. Due to the involvement of new functions and data types, from the perspective of end-to-end service transmission, it is necessary to design an end-to-end protocol stack architecture and transmission bearer method for AIoT service data transmission. The protocol stack may involve multiple functions or interfaces between network nodes and their protocol stacks. Parts of the existing 5G system's protocol stack and bearer method can be reused, or new designs can be created or enhancements based on existing solutions can be made. While some preliminary network architecture schemes have been proposed in the latest 3GPP SA2 Release 19 work items, a unified AIoT service protocol architecture and operation command and data bearer scheme have not yet been formed.

[0010] Question 2: Security configuration and execution result reporting process when AIoT operation commands are executed.

[0011] Given the existence of various AIoT operation commands and data transmission methods, as well as multiple methods for triggering commands, designing a unified AIoT Uu interface security configuration process is essential. Furthermore, designing a unified process for the core network to report AIoT operation command execution result statistics is also crucial for billing and other operations.

[0012] Question 3: Basic process of mobility management for UE readers and AIoT devices

[0096] To make the objectives, technical solutions, and advantages of this application clearer, some embodiments of this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0097] The technical terms used in this article are explained below:

[0098] Table 1

[0099] In particular, in the following description, UE reader and reader UE, base station reader and reader NB are used interchangeably and are not clearly distinguished.

[0100] Based on the progress of existing technical solutions, four topologies for AIoT systems have been defined. Currently, it has been determined that only half of these topologies will be studied in 3GPP Release 19.

[0101] Referring to Figures 1 to 4, various topologies for Ambient Internet of Things (A-IoT) are illustrated below. The base station mentioned in this application can be one of the base stations 20a in Figures 1 to 4. The terminal or A-IoT terminal mentioned in this application can be one of the A-IoT terminals in Figures 1 to 4, such as one of A-IoT terminals 40a-40n (in Figures 1 to 4, A-IoT terminal is abbreviated as IoT terminal). In this document, A-IoT terminal can be simply referred to as IoT terminal, or simply terminal.

[0102] As shown in Figure 1, in the first network topology of A-IoT, the base station 20a connects to multiple A-IoT terminals, including A-IoT terminals 40a, 40b, ..., 40n. Here, n can be a positive integer. The base station 20a and the IoT terminals 40a are directly connected for uplink / downlink communication, meaning that the IoT terminal 40a sends information to or receives information from the base station 20a. The interface between the base station and the IoT terminals can be called the A-IoT air interface.

[0103] As shown in Figure 2, in the second network topology of A-IoT, base station 20a is connected to intermediate node 31a. Intermediate node 31a connects to multiple A-IoT terminals, including A-IoT terminals 40a, 40b, ... 40n. Uplink / downlink communication occurs between A-IoT terminals 40a and intermediate node 31a, and uplink / downlink communication also occurs between intermediate node 31a and base station 20a. That is, A-IoT terminals 40a send or receive information from intermediate node 31a, and intermediate node 31a sends or receives information from base station 20a. The interface between the base station and the intermediate node can be called a Uu air interface, such as the Uu air interface of NR or LTE, or a 6G Uu air interface. The interface between the intermediate node and the IoT terminals can be called an A-IoT air interface.

[0104] The intermediate node 31a can be a relay, an integrated access backhaul (IAB) node, a UE, or a repeater, etc.

[0105] As shown in Figure 3, in the third network topology of A-IoT, base station 20a connects to auxiliary node 32a and connects to multiple A-IoT terminals, including A-IoT terminals 40a, 40b, ... 40n. Specifically, the third network topology has several forms. For example, in the downlink direction, transmission needs to be through the auxiliary node 32a, but in the uplink direction, transmission does not need to be through the auxiliary node 32a, as explained below.

[0106] In the downlink direction, the auxiliary node 32a and the A-IoT terminal 40a communicate with each other, that is, the A-IoT terminal 40a receives information from the auxiliary node 32a, and the auxiliary node 32a receives information from the base station 20a.

[0107] In the uplink direction, the A-IoT terminal 40a communicates with the base station 20a, that is, the A-IoT terminal 40a sends information to the base station 20a.

[0108] For example, transmission may not need to be carried out through the auxiliary node 32a in the downlink direction, but it may need to be carried out through the auxiliary node 32a in the uplink direction, as explained below.

[0109] In the downlink direction, the A-IoT terminal 40a communicates with the base station 20a, that is, the A-IoT terminal 40a receives information from the base station 20a.

[0110] In the uplink direction, the auxiliary node 32a and the A-IoT terminal 40a communicate with each other, that is, the A-IoT terminal 40a sends information to the auxiliary node 32a, and the auxiliary node 32a sends information to the base station 20a.

[0111] The auxiliary node 32a can be a relay, an integrated access backhaul (IAB) node, a UE, or a repeater, etc.

[0112] The interface between the base station and the auxiliary node can be called the Uu air interface, such as the Uu air interface for NR or LTE, or the Uu air interface for 6G. The interface between the auxiliary node and the IoT terminal, and between the base station and the IoT terminal, can be called the A-IoT air interface.

[0113] As shown in Figure 4, in the fourth network topology of A-IoT, UE 10a directly connects to multiple A-IoT terminals, including A-IoT terminals 40a, 40b, ... 40n. The UE and the A-IoT terminal 40a are directly connected for uplink / downlink communication. The A-IoT terminal 40a sends information to the UE or receives information from the UE. The interface between the UE and the IoT terminal can be called the A-IoT air interface.

[0114] Environmental IoT terminal types:

[0115] In this application, environmental A-IoT can also be called passive IoT, semi-passive IoT, zero-power IoT, low-power IoT, or ultra-low-power IoT. This application does not limit the name of environmental A-IoT. Environmental IoT terminals can be divided into two categories: one is A-IoT terminals that can generate signals themselves; the other is A-IoT terminals that cannot actively generate signals. These A-IoT terminals that cannot actively generate signals need to receive backscattered signals from a third-party signal (i.e., carrier wave) and then transmit them. Therefore, these A-IoT terminals can also be called A-IoT terminals based on backscatter communication. Since backscatter communication does not actively generate carrier signals, the power consumption of A-IoT terminals based on backscatter communication is lower than that of the former type of A-IoT terminal (A-IoT terminals that can generate signals), and their capabilities are also lower than those of the former type of A-IoT terminal. In the above network topologies 1 to 4, the signals sent by the A-IoT terminal 40a to the base station 20a, the intermediate node 31a, the auxiliary node 32a, or the UE can be self-generated signals or backscattered signals.

[0116] Unlike the signal modulation and transmission processes in traditional communication, IoT terminals supporting backscatter communication do not possess carrier generation capabilities and cannot "actively" transmit signals. Instead, they modulate the information they need to send using a third-party signal. The IoT terminal selects the appropriate load impedance based on the information it needs to send, thereby altering the amplitude, phase, or frequency of the third-party signal's physical properties, thus achieving "passive" communication. Modulation is divided into digital modulation and analog modulation. A simple implementation involves the IoT terminal (e.g., the A-IoT terminal 40a) reflecting the carrier signal when it sends a bit "1" and absorbing the carrier signal when it sends a bit "0".

[0117] The backscatter communication principle described above primarily involves the transmitting end. A typical IoT terminal supporting backscatter communication, besides including the channel coding and modulation module for the transmitting end, usually also includes an antenna, microcontroller, signal receiving module, and memory. The signal receiving module is responsible for receiving downlink signals sent to the IoT terminal from the network side or a card reader. The microcontroller is responsible for executing commands, collecting sensor information, writing / reading data, and controlling the coding and modulation modules according to the information to be transmitted. Because backscatter communication does not actively generate carrier signals, its power consumption is extremely low.

[0118] Referring to Figure 5, one or more core network devices (e.g., core network device 30) running the core network functions are connected to multiple base stations, including base stations 20a, 20b, ... 20m. Base stations 20a and 20b can be referred to as the first base station and the second base station. In some examples, base station 20a can act as a source base station, and base station 20b can act as a target base station. The multiple base stations are connected to multiple user equipments (UEs), including UEs 10a, 10b, ... 10n, via wireless channels. m and n can be positive integers.

[0119] The network entity device 30 can be a node in the CN. The CN can include an LTE CN or a 5G core (5GC), which includes User Plane Function (UPF), Session Management Function (SMF), Access and Mobility Management Function (AMF), Unified Data Management (UDM), Policy Control Function (PCF), Control Plane (CP) / User Plane (UP) separation (CUPS), Authentication Server (AUSF), Network Slice Selection Function (NSSF), and Network Exposure Function (NEF).

[0120] Examples of UEs described herein may include one of UE 10a, UE 10b, ..., or UE 10n. Examples of base stations described herein may include base station 20a or 20b. The network may be a network node of the base station or the core network. Examples of base stations may be gNB, eNB, or other base stations. Uplink (UL) transmission of control signals or data may be a transmission operation from the UE to the base station. Downlink (DL) transmission of control signals or data may be a transmission operation from a base station to a UE. DL control signals may include a Medium Access Control (MAC) control element (CE), Downlink Control Information (DCI), or Radio Resource Control (RRC) signal from a base station to a UE.

[0121] To address the aforementioned issues, this invention first proposes an AIoT service support system based on a 5G mobile communication system. This system adds AIoT service-related functions or network nodes to the existing 5G infrastructure and provides interfaces between these functions or nodes. In addition to adding new functions and nodes, existing functions or nodes and their interfaces are enhanced. The system also provides possible protocol stacks for the function or node interfaces to support AIoT services. Some interfaces introduce new protocol layers, while existing protocol layers are reused but enhanced. See Example 0 for details.

[0122] Based on this, the invention provides a complete AIoT service process and introduces methods for transmitting signaling messages and service data. There are three main schemes: Scheme 1, both the UE reader and the NB reader transmit signaling messages and service data via control plane signaling messages; Scheme 2, the NB reader transmits via control plane signaling messages, while the UE reader transmits via user plane or channel; Scheme 3, both the UE reader and the NB reader transmit via user plane or channel. See Examples 1 to 3 for details.

[0123] This invention proposes a corresponding method to address the requirements for security configuration and statistical reporting of execution results of the AIoT Uu interface in AIoT business processes. This method employs different business processes depending on the triggering reason, and details the processes for UE readers and NB readers respectively, as shown in Examples 4 and 5.

[0124] In view of the mobility characteristics of devices and readers, this invention further provides a mobility management process for devices and readers, including a location update process and a method for determining the association between devices and readers. Specific methods are described in Examples 6 and 7.

[0322] For details regarding 3GPP-defined 3G / 4G / 5G mobile communication systems, their corresponding network nodes, interface protocols, and functions, please refer to the corresponding 3GPP standards and specifications. In 3GPP mobile communication systems, the "Control Plane" (CP) and "User Plane" (UP) are two key concepts with distinct differences and unique functions.

[0323] Definition of the control plane: The control plane encompasses all signaling processes used to establish, maintain, and release network connections. This includes access procedures between user equipment (UE) and the network, mobility management, session management, security control, etc. In short, the control plane is responsible for the management and control functions of the network.

[0324] Definition of User Plane: The user plane is primarily responsible for carrying the actual data transmission of users. It is the transmission channel for the real business data, carrying user data such as voice data or packet service data. The user plane transmits user-generated data content, excluding signaling data used within the network for connection maintenance and management.

[0325] In Example #1, both the UE reader and the base station reader receive and send network-side information via control plane signaling messages:

[0326] As shown in Figures 10 and 11, this invention discloses a system and method for receiving and sending AIoT service-related operation commands and / or data through a mobile communication system, including:

[0327] The UE or base station receives an AIoT operation command request from AMF 31 and / or AIoTF 32 via control plane signaling messages and sends the AIoT operation command request to AIoT device 40; and / or receives the AIoT operation command result from AIoT device 40 and sends the AIoT operation command result to AMF 31 and / or AIoTF 32 via control plane signaling messages;

[0331] 1. In a scenario where the AIoT reader is located within a User Equipment (UE), the control plane signaling messages received by the UE for receiving AIoT operation command requests include NAS signaling messages and RRC signaling messages. As shown in step 4 of Figure 11, the NAS signaling messages are sent from AMF 31 and / or AIoTF 32 to the gNB via the downlink NAS transport process and messages of the NGAP protocol, and then from the gNB to the UE via the downlink information transfer process and messages of the RRC protocol; the downlink NAS transport and downlink information transfer messages may include NAS signaling messages related to multiple AIoT devices.

[0332] 2. In scenarios where the AIoT reader is located within a User Equipment (UE), the control plane signaling message used by the UE to send the AIoT operation command result includes NAS signaling messages and RRC signaling messages. As shown in step 8 of Figure 11, the NAS signaling message is sent from the UE to the gNB via the uplink information transfer (UL information transfer) process and messages of the RRC protocol, and then from the gNB to the AMF 31 and / or AIoTF 32 via the uplink NAS transport (Uplink NAS Transport) process and messages of the NGAP protocol; the uplink NAS transport message may also include information about the number of AIoT devices involved in the AIoT operation command; the uplink NAS transport message and the uplink information transfer message may include NAS signaling messages related to multiple AIoT devices;

[0338] 1. The AIoT device 40 executes the AIoT operation command, as shown in step 6 of Figures 11 and 12.

[0339] 2. If AMF 31 and AIoTF 32 are independent of each other, the process further includes AIoTF 32 sending an AIoT operation command request to AMF 31 via control plane signaling messages, as shown in step 3 of Figures 11 and 12; and AMF 31 sending the AIoT operation command result to AIoTF 32 via control plane signaling messages, as shown in step 9 of Figures 11 and 12.

[0340] 3. AIoTF 32 and / or AMF 31 receive AIoT operation command requests from AIoT server / AF 33 via control plane signaling messages, as shown in step 1 of Figures 11 and 12; and send the AIoT operation command results to AIoT server / AF 33 via control plane signaling messages, as shown in step 10 of Figures 11 and 12;

[0342] In Example #2, base station readers receive and send network-side information via control plane signaling messages, while UE reader 10 receives and sends network-side information via user plane transport bearer or channel.

[0343] As shown in Figure 13, this invention discloses a system and method for receiving and sending AIoT service-related operation commands and / or data through a mobile communication system, including:

The user plane bearer or channel includes at least one of the following user plane bearers or channels:

[0355] As shown in Figure 14, steps 3 and 4 can also be completed in advance, that is, the user plane transmission bearer or channel related to AIoT services for the UE has been established. In this case, steps 3 and 4 are not performed, and the user plane transmission bearer or channel is used directly.

[0356] In Example #3, both the UE reader and the base station reader receive and transmit network-side information via the user plane transmission bearer:

[0362] 3. IP-based transmission channel / tunnel between UPF 34 and data network (DN).

[0363] As shown in Figures 16 and 17, steps 5 and 9 involve the UE and the base station receiving AIoT operation command requests from the AIoT server and / or AF in the form of data packets through the user plane transmission bearer or channel, and sending AIoT operation command result data to the AIoT server and / or AF.

[0389] Example #6 Mobility Management of Readers and AIoT Devices 1

[0390] Regarding mobility management, i.e., location management, for AIoT device 40, the AIoT device currently does not perform connection-based location update procedures because it lacks dedicated connections with the network side, including connections to the access network (AS layer) and the core network (Non-Access Network, NAS). Furthermore, the AIoT device may not proactively initiate signaling and data transmission, meaning it will not perform proactive location update procedures based on location changes. Therefore, the AIoT device itself does not perform location update-related procedures. On the other hand, since the AIoT device accesses the mobile communication network through readers (including UE reader 10 and NB reader 20), its location information is associated with a specific reader. However, the reader's location and status can change due to mobility and environmental changes (such as changes in wireless signal strength, power on / off status), and the AIoT device's own location and status can also change due to mobility and environmental changes (such as changes in wireless signal strength, power on / off status). Therefore, the association between AIoT device 40 and the reader is variable. When it is necessary to perform AIoT business-related operations on a certain AIoT device 40, it is first necessary to determine the reader associated with the AIoT device 40 based on the location information of the AIoT device 40 and the reader. Therefore, it is necessary to perform mobility management on the reader and the AIoT device 40.

[0391] This embodiment includes at least one of the following basic operations and processes:

[0392] 1. The AIoT server / AF 33 maintains the location information of readers (including UE reader 10 or NB reader 20) and / or AIoT devices, and the maintenance operations include storage and management;

[0393] 2. The AIoT server / AF 33 establishes and maintains the association between the reader and the AIoT device 40. This association can be based on location information, such as the same location range, where the location range can be determined based on the reader's location information and the reader's coverage area. The maintenance operations include storage and management.

[0394] 3. When executing AIoT service-related operation commands, the AIoT server / AF 33 determines one or more readers involved in the AIoT service-related operation command based on the information (location information, identification information, etc.) of the AIoT device 40 and / or the reader. The location attribute of the reader can be configured to be mobile or fixed. For example, fixed readers include NB reader 20 and fixed UE reader 10; other UE readers 10 are mobile readers.

[0395] 4. The AIoT server / AF 33 maintains the time information associated with the location information, that is, obtains the time information corresponding to the location information. The maintenance operation includes storage and management.

[0396] The location information of the UE reader 10 or NB reader 20 may include the location information of the UE associated with the UE reader 10 or the NB associated with the NB reader 20, or the location information of the UE or NB after positioning measurement;

[0397] The location information of the reader and the AIoT device can be absolute location information (longitude, latitude and / or height information, etc.), or logical location information defined by the mobile communication network, such as cell, beam, tracking area information, etc.; or the location information of the AIoT device 40 relative to the reader within the reader's coverage area (such as distance, direction).

[0398] Furthermore, the process of determining the reader during AIoT service-related operation commands includes at least one of the following steps:

[0399] 1. The AIoT server / AF 33 initially determines one or more UE readers 10 or NB readers 20 involved based on AIoT device information (such as identification information and / or location information), and sends information related to the reader and / or AIoT device 40 to AIoTF 32 or AMF 31. The information related to the reader and / or AIoT device includes at least one of the following: reader identification information, AIoT device identification information, AIoT device location information, reader location information, time information associated with the location information, reader type information (UE reader 10 or NB reader 20), reader attribute information (mobile or fixed), association information between the reader and AIoT device 40, or reader status information;

[0400] 2. The AIoT server / AF 33 calculates the difference between the time information associated with the location information of the AIoT device and the current time, and determines whether the difference is less than or equal to a pre-configured or predefined threshold. If so, the location information of the AIoT device is valid; otherwise, the location information of the AIoT device is invalid. When the location information of the AIoT device is invalid or there is no location information for the AIoT device, the AIoT server / AF 33 determines one or more readers within a pre-configured area and uses the readers to execute AIoT service-related operation commands on the AIoT device 40. The pre-configured area is pre-configured for one AIoT device 40 or a group of AIoT devices 40.

[0401] Furthermore:

[0402] Method 1: For each UE reader 10 or NB reader 20, AIoTF 32 or AMF 31 further determines the reader based on its connection status. The reader determination process includes at least one of the following operations:

[0403] a. For NB reader 20, if a control plane or user plane connection is established between the NB associated with NB reader 20 and AIoTF 32 or AMF 31, then it can be determined that AIoT service-related operation commands will be executed for NB reader 20 through the control plane or user plane connection. If no control plane or user plane connection is established between the NB associated with NB reader 20 and AIoTF 32 or AMF 31, then a control plane or user plane connection establishment process is initiated between AIoTF 32 or AMF 31 and the NB associated with NB reader 20. If the connection is successfully established, then it can be determined that AIoT service-related operation commands will be executed for NB reader 20 through the control plane or user plane connection. Otherwise, the determination for NB reader 20 fails. The AIoT service-related operation commands need to be sent and received through signaling or bearers related to the control plane or user plane connection. The control plane connection can be public or specific to NB reader 20 and / or AIoT services, while the user plane connection is specific to NB reader 20 and / or AIoT services.

[0404] b. For UE reader 10, if a NAS layer connection (such as a UE-dedicated control plane NAS connection or user plane PDU session connection) and / or an AS layer dedicated connection (RRC connection) has been established for the UE associated with UE reader 10, then it can be determined that AIoT service-related operation commands will be executed for the UE reader 10 through the control plane NAS connection or user plane PDU session connection. If no NAS layer connection and / or AS layer dedicated connection have been established for the UE associated with UE reader 10, a paging is initiated to the UE associated with UE reader 10. If the UE responds to the paging and successfully establishes a NAS layer and / or AS layer connection, it can be determined that AIoT service-related operation commands will be executed for the UE reader 10 through the NAS layer and / or AS layer connection; otherwise, the determination for UE reader 10 fails. Furthermore, for the UE associated with UE reader 10, a PDU session and corresponding user plane bearer for UE reader 10 and / or AIoT services can also be established. Among them, the operation commands related to AIoT services need to be sent and received through the NAS and / or AS layer connection to the relevant signaling or bearer, and / or through the user plane bearer corresponding to the PDU session;

[0405] c. If the reader is determined to have failed (including UE reader 10 or NB reader 20), AIoTF 32 or AMF 31 shall report the failure of the operation command related to AIoT service to the AIoT server / AF 33.

[0406] Method 2: For each UE reader 10 or NB reader 20, AIoTF 32 or AMF 31 further determines the reader based on the location information of the reader and the AIoT device. The determination process includes at least one of the following operations:

[0407] a. AIoTF 32 or AMF 31 obtains the location information of the reader and AIoT device, and / or the time information associated with the location information from the AIoT server / AF 33;

[0408] b. AIoTF 32 or AMF 31 obtains the location information of the reader and AIoT device, and / or the time information associated with the location information, through the NB reader 20 control plane or user plane connection establishment process and the NAS layer and / or AS layer connection establishment process of the UE reader 10.

[0409] c. AIoTF 32 or AMF 31 obtains the UE reader's location information and / or the time information associated with the location information through the 5GC's LMF;

[0410] d. AIoTF 32 or AMF 31 triggers positioning measurement of the UE associated with UE reader 10 through LMF of 5GC, and further obtains the location information of UE reader and / or the time information associated with the location information;

[0411] e. AIoTF 32 or AMF 31 obtains the UE reader's location information and / or the time information associated with the location information through the NAS location update process (such as Tracking Area Update).

[0412] f. AIoTF 32 or AMF 31 obtains the location information of NB reader 20 and / or the time information associated with the location information through NGAP or NGAP-A related control plane signaling;

[0413] g. AIoTF 32 or AMF 31 calculates the difference between the time information associated with the reader's location information and the current time, and determines whether the difference is less than or equal to a pre-configured or predefined threshold; if so, the reader's location information is valid; otherwise, the reader's location information is invalid.

[0414] h, AIoTF 32 or AMF 31 calculate the difference between the time information associated with the location information of the AIoT device and the current time, and determine whether the difference is less than or equal to a pre-configured or predefined threshold; if so, the location information of the AIoT device is valid; otherwise, the location information of the AIoT device is invalid.

[0415] i. AIoTF 32 or AMF 31 compare the valid location information of the reader and the AIoT device 40 to determine whether the reader and the AIoT device 40 are located in the same location range, that is, to determine whether the reader can perform AIoT business-related operation commands on the AIoT device 40; wherein the location range can be determined based on the location information of the reader and the coverage range of the reader, wherein the coverage range of the reader is predefined or preconfigured.

[0416] j. For each UE reader 10 or NB reader 20, AIoTF 32 or AMF 31 determines the reader based on the reader's status information. For example, if a reader is in a powered-off state, it is determined that AIoT service-related operation commands will not be executed on the AIoT device 40 through that reader.

[0417] Reader-related location update process:

[0418] UE reader:

[0419] When the location and status of the UE reader 10 change due to mobility (such as cell update or handover) and environmental changes (such as changes in radio signal, power on / off), or when the change in the UE reader's location (absolute location) is greater than or equal to a pre-configured or pre-defined threshold, or greater than or equal to the reader's coverage area, the UE reader 10 will initiate a location update procedure. As shown in Figure 20, the UE reader 10 sends its location update information to the AIoT server / AF 33 via user plane data packets or control plane signaling messages. The location update information includes at least one of the following:

[0427] Because the location of the NB reader 20 is relatively fixed, when the state of the NB reader 20 changes due to environmental changes (such as changes in wireless signal strength, power on / off), the NB reader 20 will perform a location update process. As shown in Figure 21, the reader NB sends its location update information to the AIoT server / AF 33 via user plane data packets or NGAP signaling messages. This includes at least one of the following information:
