For example, the UE obtains the current IoT control information (included in the first parameter information, specifically, current IoT subscription control information) from Unified data management (Unified DATA MANAGEMENT, UDM) in the Registration process;

As shown in fig. 5, the present example includes the steps of:

1.

3. The AMF sends Registration Accept (registration accept) message to the UE, where the message contains the UE's current IoT service authorization information and current IoT subscription control information.

4. In the case where the Ambient IoT service authorization information indicates approval of the authorization, the UE establishes a PDU session for transmitting Ambient IoT data based on content carried by the registration accept message (e.g., security parameters).

5. The UE communicates with the Ambient IoT device and gathers Ambient IoT data based on content carried by the registration accept message (e.g., single or continuous reports).

6. The UE reports the Ambient IoT data to the Ambient IoT APP SERVER (AIoT application server) via AIoT data reports based on the content carried by the registration accept message (e.g., address of Ambient IoT data report).

Secondly, the UE obtains the current IoT control information (which is included in the first parameter information and may specifically be current IoT subscription control information) from AIoT management functions (devices) in the Registration process;

In order to support communication between the mobile IoT device and the network, a new core network element Ambient IoT Management Function (AIoT management function) is introduced, and the network element is a control plane network element, and can provide services to other network elements (such as AMF).

The UE initiates a Registration procedure, and the Registration Request message (corresponding to the first request message) includes capability indication information that the UE supports communication with the Ambient IoT device, requested Ambient IoT information (e.g., qoS parameters (corresponding to the QoS parameter information) that the UE requests to communicate with the Ambient IoT device, security parameters (information), communication duration, service location, reporting period, single or continuous reporting, ambient IoT device identification (corresponding to the identification information), address (such as UPF address or NEF address or Ambient IoT management function address) of Ambient IoT data reporting, and so on.

2. The AMF obtains the Ambient IoT management data of the UE from the Ambient IoT management function, wherein the Ambient IoT management data comprises Ambient IoT service authorization information (namely whether the UE is authorized to communicate with the Ambient IoT device), ambient IoT subscription control information (such as QoS parameters of the communication between the UE and the Ambient IoT device (corresponding to QoS parameter information authorized by the network), security parameters (corresponding to security parameter information authorized by the network), communication duration, service location, reporting period, single or continuous reporting, ambient IoT device identification, address (such as UPF address or NEF address or Ambient IoT management function address) of the Ambient IoT data reporting and the like.

Thirdly, the UE obtains the current IoT control information (which is included in the first parameter information and may be specifically current IoT control information) from the policy control function (Policy Control Function, PCF) in the Registration process;

as shown in fig. 7, the present example includes the steps of:

1. The UE sends Registration Request a message to the AMF, and Registration Request the message (corresponding to the first request message) includes capability indication information that the UE supports communication with the Ambient IoT device, requested Ambient IoT information (e.g., qoS parameters (corresponding to the QoS parameter information) that the UE is requesting to communicate with the Ambient IoT device, security parameters (information), communication duration, service location, reporting period, single or continuous reporting, ambient IoT device identification (corresponding to the identification information), address of Ambient IoT data reporting (e.g., UPF address, NEF address, or Ambient IoT management function address), etc.

2. The AMF returns Registration Accept a message to the UE after completing the Registration procedure.

3. If the UE supports communication with the Ambient IoT device, the network subscription in turn 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 Ambient IoT policy information (policy management data), and specifically, the AMF forwards capability indication information that the UE supports communication with the Ambient IoT device, and the requested Ambient IoT information to the PCF. Regarding the condition that the network subscription allows the UE to communicate with the current IoT device, the AMF may determine whether the subscription is satisfied according to the subscription information of the UE (such as current IoT mobility management subscription data of the UE obtained from the UDM), and it should be noted that the subscription information in this example only carries authorization information (i.e., current IoT service authorization information) and does not carry current IoT control information, but is not limited thereto.

4. The PCF returns a response message (i.e., a terminal policy control creation response) to the AMF.

5. The PCF sends a transmission message (i.e., policy management data, or carries policy management data) to the AMF, where the message (policy management data) includes information such as an Ambient IoT service authorization information (i.e., whether the UE is authorized to communicate with the Ambient IoT device, authorization information corresponding to the terminal communicating with the AIoT device), ambient IoT policy control information (e.g., qoS parameters of the UE communicating with the Ambient IoT device (QoS parameter information corresponding to the network authorization), security parameters (security parameter information corresponding to the network authorization), a communication duration, a service location, a reporting period, a single or continuous report, an Ambient IoT device identifier, an address of the Ambient IoT data report (e.g., a UPF address or a NEF address or an Ambient IoT management function address), and the like.

6. The AMF forwards the Ambient IoT service authorization information and the Ambient IoT policy control information to the UE via NAS messages (terminal policy delivery).

7. In case the Ambient IoT service authorization information indicates grant of authorization, the UE establishes a PDU session for transmitting Ambient IoT data based on content carried by the NAS message, such as security parameters.

8. The UE communicates with and collects the Ambient IoT devices based on content carried by the NAS message (e.g., single or continuous reports).

9. The UE reports the Ambient IoT data to Ambient IoT APP SERVER via AIoT data reports based on content carried by the NAS message (e.g., the address of the Ambient IoT data report).

The fourth example is that the UE obtains the current IoT control information (contained in the first parameter information) from the UDM or PCF during the PDU Session establishment;

as shown in fig. 8, the present example includes the steps of:

1. The UE sends a PDU Session establishment request message to the SMF (device), in which the UE indicates to the SMF that a PDU Session (i.e., AIoT PDU Session carrying the request) requesting to establish transmission of the event IoT data is to be established. Steps 2 or 3 (including steps 3a and 3b in the figure) are performed as follows, followed by 4-6.

2. The SMF obtains the current IoT session management subscription data of the UE from the UDM, where the data may include PDU session authorization information (i.e., whether the UE is allowed to establish a PDU session to transmit the current IoT data, corresponding to authorization information for the terminal to communicate with the AIoT device), current IoT subscription control information (e.g., qoS parameters of the UE to communicate with the current IoT device (corresponding to QoS parameter information of the network authorization), security parameters (corresponding to security parameter information of the network authorization), communication duration, service location, reporting period, single or continuous reporting, current IoT device identification, address of current IoT data reporting (such as UPF address or NEF address or current IoT management function address), and so on.

3. The SMF obtains, from the PCF, the UE's current IoT policy management data (i.e., policy data, which may also be referred to as AIoT policy data) that may include PDU session authorization information (i.e., authorization information whether the UE is allowed to establish a PDU session to transmit current IoT data, corresponding to the terminal communicating with the AIoT device), current IoT policy control information (e.g., qoS parameters of the UE communicating with the current IoT device (corresponding to the QoS parameter information of the network authorization), security parameters (corresponding to the security parameter information of the network authorization), communication duration, service location, reporting period, single or continuous reporting, current IoT device identification, address of current IoT data reporting (e.g., UPF address or NEF address or current IoT management function address), etc. The SMF may obtain the mobile IoT policy management data of the UE from the PCF, and may include, but not limited to, sending a session management policy control creation request to the PCF and receiving a session management policy control creation response fed back by the PCF (carrying AIoT policy management data).

4. The SMF returns a PDU session establishment acceptance message to the UE, where the message may include PDU session authorization information (i.e. whether the UE is allowed to establish a PDU session and transmit the current IoT data, corresponding to the authorization information that the terminal communicates with the AIoT devices), current IoT control information (e.g. QoS parameters of the UE communicating with the current IoT devices (corresponding to the QoS parameter information of the network authorization), security parameters (corresponding to the security parameter information of the network authorization), communication duration, service location, reporting period, single or continuous reporting, current IoT device identification, address of current IoT data reporting (such as UPF address or NEF address or current IoT management function address), and so on). The current IoT control information may be obtained by the SMF according to the current IoT subscription control information or the current IoT policy control information, but is not limited thereto.

5. In the case where the PDU session grant information indicates grant permission, the UE communicates with the Ambient IoT device and gathers Ambient IoT data based on content carried by the PDU session establishment acceptance message (e.g., single or continuous reporting).

6. The UE reports the current IoT data to the current IoT APP SERVER through AIoT data reports based on the content carried by the PDU session establishment acceptance message (such as the address of the current IoT data report) and the PDU session corresponding to the PDU session establishment acceptance message.
