step 2b: data notification acknowledgement: the SMF feeds back data notification acknowledgement to the UPF;

step 2c: the UPF sends downlink data to the SMF: if the SMF instructs the UPF to perform this step, the UPF forwards the downlink data packet to the SMF (i.e., the SMF will buffer the data packet);

step 3a: namf-communication-N1N 2 message transmission: the SMF sends a network access and mobility management function (Network Access and Mobility Management Function, namf) _communication_n1n2 message transmission request to the AMF, the request including (SUPI, PDU session ID, N1 session management (Session Management, SM) container (SM message), N2 SM information (quality of service (Quality of Service, qoS) flow identifier, qoS profile, CN N3 tunnel information, s-network slice selection assistance information (Network Slice Selection Assistance Information, nsai)), wherein CN N3 may be, for example, the N3 interface of the core network;

Step 3b: namf-communication-N1N 2 message transmission response;

step 4a: reactivation: if the terminal is in a connection manager (Connection Manager, CM) -CONNECTED state in the access associated with the PDU session ID received from the SMF in step 3a, steps 4 to 22 (see clause 4.2.3.2) in the terminal trigger service request procedure are performed for the PDU session (i.e. radio resources are established and, in case the user plane is to be activated, AN N3 tunnel is established) without sending paging messages to the radio access network (Radio Access Network, (R) AN) node and the terminal;

step 4b: paging: when the terminal is in the cm_idle IDLE state, the AMF transmits a CN paging message to the RAN. The RAN sends a paging message to the terminal;

step 4c: NAS notification;

step 5: namf-communication-N1N 2 transmission failure notification: AMF sends Namf_communication_N1N2 transmission failure notification to SMF;

step 6: service request procedure: if the terminal is in the CM-IDLE state in the third generation partnership project (3rd Generation Partnership Project,3GPP) access, upon receiving a paging request for a Packet Data Unit (PDU) session associated with the 3GPP access, the terminal should initiate a terminal trigger service request procedure to enter the cm_connected state to activate/create a user plane connection to deliver downlink Data.

Step 6a: namf-communication-N1N 2 transmission failure notification: AMF sends Namf_communication_N1N2 transmission failure notification to SMF;

step 7: terminal configuration update program: if the AMF has paged the terminal to trigger the service request procedure, the AMF should initiate a terminal configuration update procedure defined in clause 4.2.4.2 to assign a new fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) -globally unique temporary identifier (Globally Unique Temporary Identifier, GUTI);

step 8: the UPF transmits buffered downlink data to the terminal through the (R) AN node performing the service request procedure.

In one embodiment of the present disclosure, when there is downlink data from the network to the terminal, the network triggers the paging of the terminal and a connection must be created between the terminal and the RAN, e.g., by triggering a service request procedure into a connected state and/or activating/creating a user plane connection to download the downlink data from the network. However, for an ambient internet of things device, the downlink data may be very small, e.g. a few bits dedicated to instructions, and the ambient internet of things device is defined as a passive device or a very power limited device, so the above procedure is not necessary and efficient. The passive device may be, for example, a device without a power supply.

Alternatively, in one embodiment of the present disclosure, transmission of the instruction may be performed in case of establishment of a connection between the terminal and the RAN, so that the terminal may perform an operation corresponding to the instruction. Paging messages are only used for network paging terminals, and the transmission mechanism of the attachment information except paging effect is not clear, so that the message transmission efficiency is low.
