Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0131] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0132] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0133] It is explained here that the technical solution provided by the embodiment of the present disclosure can be applicable to a variety of systems, especially the fifth generation mobile communication (5th-Generation, 5G) system. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal devices and network devices. The system may also include core network parts, such as the Evolved Packet System (EPS), 5G System (5GS), etc.

[0134] Figure 1 shows a block diagram of a wireless communication system to which embodiments of the present disclosure may be applied. The wireless communication system includes a terminal device (also referred to as a terminal) and a network device.

[0135] The terminal device involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called User Equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0136] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be named by another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network.

It can also use diversity transmission, precoding, or beamforming.

[0138] The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

[0139] Research is currently underway to connect Ambient IoT devices to 5G networks for communication, thereby achieving the goal of a fully connected 5G network. User equipment (UE) or 5G base stations (gNB) can act as readers to read data from Ambient IoT devices and report it to the network and / or Ambient IoT applications. This includes:

[0140] (1) Ambient IoT scenarios;

[0141] Related projects have studied Ambient IoT scenarios. Ambient IoT can be widely applied in scenarios such as automated logistics, smart grids, internal factory logistics in manufacturing, and sensor data reporting in smart homes. For example, in automated warehousing scenarios, Ambient IoT technology can be used to count goods as they enter and exit the warehouse.

[0142] (2) Ambient IoT device types;

[0143] Related projects have studied the types of Ambient IoT devices. Specifically, Ambient IoT devices can be divided into the following three types:

[0144] Device A: No energy storage, no independent signal generation / amplification, i.e. backscattering transmission.

[0145] Device B: Has energy storage, no independent signal generation, i.e., backscattering transmission. Use of stored energy can include amplification for reflected signals.

[0146] Device C: Has energy storage, has independent signal generation, i.e., active RF components for transmission.

[0147] Device A and / or B relies on backscatter transmission to transmit data, making it difficult to implement Radio Resource Control (RRC) and / or Non-Access Stratum (NAS) connections between the Ambient IoT device and the network. A UE Reader or gNB Reader is required to read the data from the Ambient IoT device and then report it to the network and / or Ambient IoT application.

[0148] Specifically, the UE Reader can be shown in Figure 2. Similar to the Reader in RFID technology that reads data in a tag, the UE can act as a Reader to read data in an Ambient IoT device and report it to the Ambient IoT App Server over the network.

[0149] Based on the above, the embodiments of the present disclosure provide a communication method, apparatus, and device to address the problem in related technologies of being unable to accurately implement communication between UE and AIoT devices. The method, apparatus, and device are based on the same patent application concept. Since the principles for solving the problems in the method, apparatus, and device are similar, the implementation of the method, apparatus, and device can refer to each other, and any repetitions will not be repeated.

[0162] In an embodiment of the present disclosure, the first parameter information is obtained by the network device from a unified data management (UDM) device, a policy control function (PCF) device, or an AIoT management function device.

[0171] This can support the terminal to actively initiate communication.

[0173] In this way, the network device side can know the QoS parameter information and / or security parameter information required by the terminal.

[0174] In the embodiment of the present disclosure, the obtaining of the first parameter information for the terminal to communicate with the enabled Internet of Things AIoT device includes: obtaining the first parameter information for the terminal to communicate with the enabled Internet of Things AIoT device from a unified data management UDM device, or a policy control function PCF device, or an AIoT management function device.

[0175] This can clarify the source of the first parameter information.

[0176] The identification information of the AIoT device is a permanent identification or a temporary identification of the AIoT device.

[0177] This can clarify the specific identification information of the AIoT device.

[0178] In an embodiment of the present disclosure, the network device is an access and mobility management function AMF device, the first request message is a registration request message, and the first feedback message is a registration acceptance message or a downlink non-access layer NAS transmission message; or, the network device is a session management function SMF device, the first request message is a protocol data unit PDU session establishment request message, and the first feedback message is a PDU session establishment acceptance message.

[0179] This makes it clear that this solution can be implemented during the registration process or the PDU session establishment process.

[0180] The communication method provided in the embodiment of the present disclosure is illustrated below with examples, taking AMF or SMF as an example of a network device.

[0181] To address the above technical issues, the present disclosure provides a communication method, which can be implemented as a method for controlling a (network-to-UE) terminal reader (UE Reader) to control the data collection and reporting of Ambient IoT devices. Specifically, this solution includes the following:

[0182] Method 1: During the UE registration process, the AMF (device) can provide the UE with control information as a UE Reader (included in the above-mentioned first parameter information) based on mobility management subscription data (corresponding to Example 1 below), or based on AIoT management data (corresponding to Example 2 below), or based on policy management data (corresponding to Example 3 below).

[0183] Method 2: During the UE PDU session establishment process, the SMF can provide the UE with control information as a UE Reader based on the session management subscription data or policy data (corresponding to Example 4 below).

[0184] The following is a specific example of this solution.

[0185] Example 1: The UE obtains Ambient IoT control information (included in the first parameter information above, specifically Ambient IoT subscription control information) from the UDM during the Registration process.

[0186] As shown in Figure 5, this example includes the following steps:

[0187] 1. The UE initiates a Registration process, and the Registration Request message (corresponding to the first request message) includes: information indicating the UE's ability to support communication with the Ambient IoT device, requested Ambient IoT information (for example, the QoS parameters requested for communication between the UE and the Ambient IoT device (corresponding to the QoS parameter information), security parameters (information), communication duration, service location, reporting period, single or continuous reporting (i.e., reporting type for data collected from the Ambient IoT device), Ambient IoT device identifier (corresponding to the above-mentioned identifier information), and the address for reporting Ambient IoT data (i.e., data collected from the Ambient IoT device) (such as the user plane function (UPF) address or the network exposure function (NEF) address or the Ambient IoT management function address). The above-mentioned service location may include, but is not limited to, the location of the UE capable of communicating with the Ambient IoT device.

[0188] 2. AMF obtains the Ambient IoT mobility management subscription data of the UE from the UDM, which may include: Ambient IoT service authorization information (i.e., whether the UE is authorized to communicate with the Ambient IoT device, corresponding to the authorization information for the above-mentioned terminal to communicate with the Ambient IoT device), Ambient IoT subscription control information (such as QoS parameters for communication between the UE and the Ambient IoT device (corresponding to the QoS parameter information authorized by the above-mentioned network), security parameters (corresponding to the security parameter information authorized by the above-mentioned network), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification, Ambient IoT data reporting address (such as UPF address or NEF address or Ambient IoT management function address) and other information).

[0189] 3. AMF sends a Registration Accept message to the UE, which contains the UE's Ambient IoT service authorization information and Ambient IoT contract control information.

[0190] 4. If the Ambient IoT service authorization information indicates that the authorization is approved, the UE establishes a PDU session for transmitting Ambient IoT data based on the content carried in the registration acceptance message (such as security parameters).

[0191] 5. The UE communicates with the Ambient IoT device and collects Ambient IoT data based on the content carried in the registration acceptance message (such as single or continuous reporting).

[0192] 6. Based on the content carried in the registration acceptance message (such as the address for reporting Ambient IoT data), the UE reports the Ambient IoT data to the Ambient IoT App Server through the AIoT data report.

[0193] Example 2: The UE obtains the Ambient IoT control information (included in the first parameter information above, specifically the Ambient IoT subscription control information) from the AIoT management function (device) during the Registration process.

[0194] To support communication between Ambient IoT devices and the network, this example introduces a new core network element, the AIoT Management Function. This element is a control plane element that can provide services to other network elements (such as AMF). As shown in Figure 6, this example includes the following steps:

[0195] 1. The UE initiates the Registration process, and the Registration Request message (corresponding to the above-mentioned first request message) includes: the UE's ability indication information for supporting communication with the Ambient IoT device, the requested Ambient IoT information (for example, the QoS parameters for the requested UE to communicate with the Ambient IoT device (corresponding to the above-mentioned QoS parameter information), security parameters (information), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification (corresponding to the above-mentioned identification information), and the address for Ambient IoT data reporting (such as UPF address or NEF address or Ambient IoT management function address).

[0196] 2. AMF obtains the Ambient IoT management data of the UE from the Ambient IoT management function, including: Ambient IoT service authorization information (i.e. whether the UE is authorized to communicate with the Ambient IoT device), Ambient IoT contract control information (such as QoS parameters for communication between the UE and the Ambient IoT device (corresponding to the QoS parameter information authorized by the above network), security parameters (corresponding to the security parameter information authorized by the above network), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification, Ambient IoT data reporting address (such as UPF address or NEF address or Ambient IoT management function address) and other information).

[0197] 3. AMF sends a Registration Accept message to the UE, which contains the UE's Ambient IoT service authorization information and Ambient IoT contract control information.

[0198] 4. If the Ambient IoT service authorization information indicates that the authorization is approved, the UE establishes a PDU session for transmitting Ambient IoT data based on the content carried in the registration acceptance message (such as security parameters).

[0199] 5. The UE communicates with the Ambient IoT device and collects Ambient IoT data based on the content carried in the registration acceptance message (such as single or continuous reporting).

[0200] 6. Based on the content carried in the registration acceptance message (such as the address for reporting Ambient IoT data), the UE reports the Ambient IoT data to the Ambient IoT App Server through the AIoT data report.

[0201] Example 3: The UE obtains Ambient IoT control information (included in the first parameter information above, specifically Ambient IoT policy control information) from the PCF during the Registration process.

[0202] As shown in Figure 7, this example includes the following steps:

[0203] 1. The UE sends a Registration Request message to the AMF. The Registration Request message (corresponding to the first request message above) includes: the UE's ability to support communication with the Ambient IoT device, the requested Ambient IoT information (for example, the QoS parameters for the requested UE to communicate with the Ambient IoT device (corresponding to the above QoS parameter information), security parameters (information), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification (corresponding to the above identification information), and the address for Ambient IoT data reporting (such as UPF address, NEF address or Ambient IoT management function address).

[0204] 2. After completing the Registration process, the AMF returns a Registration Accept message to the UE.

[0205] 3. If the UE supports communication with the Ambient IoT device and the network contract allows the UE to communicate with the Ambient IoT device, the AMF sends a request message (terminal policy control creation request) to the PCF to request the Ambient IoT policy information (policy management data). Specifically, the AMF forwards the UE's ability indication information to support communication with the Ambient IoT device and the requested Ambient IoT information to the PCF. Among them, regarding the condition that "the network contract allows the UE to communicate with the Ambient IoT device", the AMF can determine whether it is met based on the UE's contract information (such as the UE's Ambient IoT mobility management contract data obtained from the UDM); it should be noted that the contract information in this example only carries authorization information (i.e., Ambient IoT service authorization information) but does not carry Ambient IoT control information, but this is not limited to this.

[0206] 4. PCF returns a response message to AMF (i.e., terminal policy control creation response).

[0207] 5. PCF sends a transmission message (i.e., policy management data, or carries policy management data) to AMF. The message (policy management data) includes: Ambient IoT service authorization information (i.e., whether the UE is authorized to communicate with the Ambient IoT device, corresponding to the authorization information for the above-mentioned terminal to communicate with the AIoT device), Ambient IoT policy control information (such as QoS parameters for communication between the UE and the Ambient IoT device (corresponding to the QoS parameter information authorized by the above-mentioned network), security parameters (corresponding to the security parameter information authorized by the above-mentioned network), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification, Ambient IoT data reporting address (such as UPF address or NEF address or Ambient IoT management function address) and other information).

[0208] 6. AMF forwards the Ambient IoT service authorization information and Ambient IoT policy control information to the UE through NAS message (terminal policy delivery).

[0209] 7. When the Ambient IoT service authorization information indicates authorization, the UE establishes a PDU session based on the content carried in the NAS message (such as security parameters) for transmitting Ambient IoT data.

[0210] 8. The UE communicates with the Ambient IoT device based on the content carried in the NAS message (e.g., single or continuous reporting) and collects Ambient IoT data.

[0211] 9. Based on the content carried in the NAS message (such as the address of the Ambient IoT data report), the UE reports the Ambient IoT data to the Ambient IoT App Server through the AIoT data report.

[0212] Example 4: The UE obtains the Ambient IoT control information (included in the first parameter information) from the UDM or PCF during the PDU Session establishment process;

[0213] As shown in Figure 8, this example includes the following steps:

[0214] 1. The UE sends a PDU Session Establishment Request message to the SMF (device), in which the UE indicates to the SMF that it is requesting to establish a PDU session for transmitting Ambient IoT data (i.e., an AIoT PDU session carrying the request). Next, execute steps 2 or 3 (including steps 3a and 3b in the figure), and then execute steps 4-6.

[0215] 2. SMF obtains the UE's Ambient IoT session management contract data from UDM, which may include: PDU session authorization information (i.e., whether the UE is allowed to establish a PDU session to transmit Ambient IoT data, corresponding to the authorization information for the above-mentioned terminal to communicate with the AIoT device), Ambient IoT contract control information (such as QoS parameters for communication between UE and Ambient IoT device (corresponding to the QoS parameter information authorized by the above-mentioned network), security parameters (corresponding to the security parameter information authorized by the above-mentioned network), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification, Ambient IoT data reporting address (such as UPF address or NEF address or Ambient IoT management function address) and other information).

[0216] 3. SMF obtains the UE's Ambient IoT policy management data (i.e., policy data, also referred to as AIoT policy data) from PCF. The data may include: PDU session authorization information (i.e., whether the UE is allowed to establish a PDU session to transmit Ambient IoT data, corresponding to the authorization information for the above-mentioned terminal to communicate with the AIoT device), Ambient IoT policy control information (e.g., QoS parameters for communication between the UE and the Ambient IoT device (corresponding to the QoS parameter information authorized by the above-mentioned network), security parameters (corresponding to the security parameter information authorized by the above-mentioned network), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification, Ambient IoT data reporting address (such as UPF address or NEF address or Ambient IoT management function address) and other information). Among them, "SMF obtains the UE's Ambient IoT policy management data from PCF" may include: SMF sends a session management policy control creation request to PCF, and receives a session management policy control creation response (carrying AIoT policy management data) fed back by PCF, but is not limited to this.

[0217] 4. SMF returns a PDU session establishment acceptance message to the UE, which may include: PDU session authorization information (i.e., whether the UE is allowed to establish a PDU session to transmit Ambient IoT data, corresponding to the authorization information for the above-mentioned terminal to communicate with the AIoT device), Ambient IoT control information (such as QoS parameters for communication between the UE and the Ambient IoT device (corresponding to the QoS parameter information authorized by the above-mentioned network), security parameters (corresponding to the security parameter information authorized by the above-mentioned network), communication duration, service location, reporting cycle, single or continuous reporting, Ambient IoT device identification, Ambient IoT data reporting address (such as UPF address or NEF address or Ambient IoT management function address) and other information). Among them, the Ambient IoT control information can be obtained by the SMF according to the above-mentioned Ambient IoT contract control information or Ambient IoT policy control information, but is not limited to this.

[0218] 5. When the PDU session authorization information indicates that the authorization is approved, the UE communicates with the Ambient IoT device and collects Ambient IoT data based on the content carried in the PDU session establishment acceptance message (such as single or continuous reporting).

[0219] 6. The UE establishes the content carried in the acceptance message (such as the address for reporting Ambient IoT data) based on the PDU session, and the PDU session corresponding to the PDU session establishment acceptance message, and reports the Ambient IoT data to the Ambient IoT App Server through the AIoT data report.
