[0136] The following first introduces the contents involved in the solution provided in the embodiment of the present application.

[0137] Currently, we are studying how Ambient IoT devices can access 5G networks for communication, so as to achieve the goal of 5G network interconnection of all things. Among them, user equipment (UE) or 5G base station (the next generation NodeB, gNB) can act as a reader to read data from Ambient IoT devices and report it to the network and / or Ambient IoT applications. The contents involved include:

[0138] (1) Ambient IoT scenarios;

[0139] Ambient IoT scenarios have been studied in existing projects. Ambient IoT can be widely used 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 when they enter and leave the warehouse.

[0140] (2) Ambient IoT device types;

[0141] The types of Ambient IoT devices have been studied in existing projects. Specifically, Ambient IoT devices can be divided into the following three types:

[0142] -Device A: No energy storage, no independent signal generation / amplification, i.e. backscattering transmission (Device A: No energy storage, no independent signal generation and / or amplification, i.e. backscattering transmission).

[0143] -Device B: Has energy storage, no independent signal generation, i.e. backscattering transmission. Use of stored energy can include amplification for reflected signals.

[0144] -Device C:Has energy storage, has independent signal generation, i.e., active RF components for transmission. RF stands for radio frequency.

[0145] Among them, Device A and / or B rely on backscatter transmission to transmit data, and it is difficult to achieve Radio Resource Control (RRC) and / or Non-Access Stratum (NAS) connection between the Ambient IoT device and the network. UE Reader or gNB Reader is required to read the data of the Ambient IoT device and then report it to the network and / or Ambient IoT application.

[0146] Specifically, UE Reader can be as follows Figure 2 As shown, similar to the Reader in RFID technology reading the data in the Tag, the UE can act as a Reader to read the data in the Ambient IoT device and report it to the Ambient IoT App Server through the network.

[0147] Based on the above, the embodiments of the present application provide a communication method, device and equipment to solve the problem that the prior art cannot accurately realize the communication between UE and AIoT devices. Among them, the method, device and equipment are based on the same application concept. Since the principles of solving the problems by the method, device and equipment are similar, the implementation of the method, device and equipment can refer to each other, and the repeated parts will not be repeated.

[0148] The communication method provided in the embodiment of the present application is applied to a terminal, such as Figure 3 As shown, the method includes:

[0169] This can support the terminal to actively initiate communication.

[0171] In this way, the network device side can know the QoS parameter information and / or security parameter information required by the terminal.

[0172] In an embodiment of the present application, the first parameter information for obtaining 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.

[0173] This makes it possible to clarify the source of the first parameter information.

[0174] Among them, the identification information of the AIoT device is a permanent identification or a temporary identification of the AIoT device.

[0175] This can clarify the specific identification information of the AIoT device.

[0176] In an embodiment of the present application, 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.

[0177] This makes it clear that the solution can be implemented during the registration process or the PDU session establishment process.

[0178] The communication method provided in the embodiment of the present application is illustrated below by way of example, with the network device taking the access and mobility management function (AMF) or the session management function SMF as an example.

[0179] In view of the above technical problems, the embodiment of the present application provides a communication method, which can be specifically implemented as a control method of (network to) UE Reader (terminal reader) to realize the control of Ambient IoT device data collection and reporting. Specifically, this solution includes the following contents:

[0180] Method 1: During the Registration process of the UE, the AMF (device) can provide the UE with control information as a UE Reader (included in the first parameter information above) based on the mobility management subscription data (corresponding to Example 1 below), or based on the AIoT (Enabled Internet of Things) management data (corresponding to Example 2 below), or based on the policy management data (corresponding to Example 3 below).

[0181] Method 2: During the UE's protocol data unit (PDU) session establishment process, the session management function (SMF) may provide the UE with control information as a UE Reader based on session management subscription data or policy data (corresponding to Example 4 below).

[0182] The following is a specific example of this solution.

[0183] Example 1: The UE obtains Ambient IoT control information (included in the first parameter information, specifically Ambient IoT subscription control information) from Unified Data Management (UDM) during the Registration process;

[0184] like Figure 5As shown, this example includes the following steps:

[0185] 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 to support communication with the Ambient IoT device, the requested Ambient IoT information (for example, the Quality of Service (QoS) parameters (corresponding to the above-mentioned QoS parameter information) for the requested UE to communicate with the Ambient IoT device, security parameters (information), communication duration, service location, reporting cycle, single or continuous reporting (i.e., the reporting type for the data collected from the Ambient IoT device), Ambient IoT device identification (corresponding to the above-mentioned identification information), and the address to which the Ambient IoT data (i.e., the data collected from the Ambient IoT device) is reported (such as the UPF address or the Network Exposure Function (NEF) address or the Ambient IoT management function address) and other information). Among them, the above-mentioned service location may include: the UE location that can communicate with the Ambient IoT device, but is not limited to this.

[0186] 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 (for example, 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).

[0187] 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.

[0188] 4. When 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 (such as security parameters) carried in the registration acceptance message.

[0189] 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).

[0190] 6. Based on the content carried in the registration acceptance 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.

[0191] Example 2: The UE obtains Ambient IoT control information (included in the first parameter information above, specifically Ambient IoT contract control information) from the AIoT management function (device) during the Registration process;

[0192] In order to support the communication between Ambient IoT devices and the network, this example introduces a new core network element Ambient IoT Management Function (AIoT management function), which is a control plane network element and can provide services to other network elements (such as AMF). Figure 6 As shown, this example includes the following steps:

[0193] 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 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-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) and other information).

[0194] 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).

[0195] 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.

[0196] 4. When 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 (such as security parameters) carried in the registration acceptance message.

[0197] 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).

[0198] 6. Based on the content carried in the registration acceptance 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.

[0199] Example 3: The UE obtains Ambient IoT control information (included in the first parameter information, specifically Ambient IoT policy control information) from a Policy Control Function (PCF) during the Registration process;

[0200] like Figure 7 As shown, this example includes the following steps:

[0201] 1. The UE sends a Registration Request message to the AMF, which includes: the UE's ability indication information 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), Ambient IoT data reporting address (such as UPF address, NEF address or Ambient IoT management function address) and other information).

[0202] 2. After completing the Registration process, AMF returns a Registration Accept message to the UE.

[0203] 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.

[0204] 4. PCF returns a response message to AMF (i.e., terminal policy control creation response).

[0205] 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 AmbientIoT management function address) and other information).

[0206] 6. AMF forwards the Ambient IoT service authorization information and Ambient IoT policy control information to the UE through NAS message (terminal policy delivery).

[0207] 7. When the Ambient IoT service authorization information indicates that the authorization is approved, the UE establishes a PDU session based on the content (such as security parameters) carried by the NAS message for transmitting the Ambient IoT data.

[0208] 8. The UE communicates with the Ambient IoT device based on the content carried by the NAS message (such as single or continuous reporting) and collects the Ambient IoT data.

[0209] 9. Based on the content carried by 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.

[0210] Example 4: The UE obtains the Ambient IoT control information (included in the first parameter information above) from the UDM or PCF during the PDU Session establishment process;

[0211] like Figure 8 As shown, this example includes the following steps:

[0212] 1. UE sends a PDU Session establishment request message to SMF (device), in which UE indicates to SMF that it requests to establish a PDU session for transmitting Ambient IoT data (i.e., an AIoT PDU session carrying the request). Execute steps 2 or 3 (including steps 3a and 3b in the figure), and then execute 4-6.

[0213] 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 (for example, 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).

[0214] 3. SMF obtains the Ambient IoT policy management data (i.e., policy data, also referred to as AIoT policy data) of the UE from the PCF, 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 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 Ambient IoT policy management data of the UE from the PCF" may include: SMF sends a session management policy control creation request to the PCF, and receives a session management policy control creation response (carrying AIoT policy management data) fed back by the PCF, but is not limited to this.

[0215] 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 based on the above-mentioned Ambient IoT contract control information or the Ambient IoT policy control information, but is not limited to this.

[0216] 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).

[0217] 6. The UE establishes the content carried in the acceptance message (such as the address of the Ambient IoT data report) based on the PDU session, and the PDU session corresponding to the acceptance message, and reports the Ambient IoT data to the Ambient IoT App Server through the AIoT data report.

[0218] It should be noted that the relevant contents of the above examples can be referenced to each other, and the repeated contents will not be repeated.

[0219] From the above, the solution provided by the embodiment of the present application solves the problem of how the network controls the UE Reader to collect and report the data of the Ambient IoT device when the UE acts as a Reader of the Ambient IoT data.
