CPE devices that have the capability to receive mobile signals and mount other terminals are used in large numbers in network deployments. In the related art, when the network side actively sends data to the terminal that is hung down by the CPE, the frame routing function defined in the 3GPP standard needs to be utilized. The Framed routing function defined in 3GPP needs to be acquired by SMF from AAA (Authentication, authorization, accounting, authentication, authorization, and Accounting) server or UDM, and then issues a data forwarding policy to UPF.

In step 151, the UPF network element configures the address of the first class terminal in the LAN according to the Framed Routing IP address segment corresponding to the user identifier required by the network side. In addition, the UPF network element generates a forwarding rule between the Framed Routing IP addresses according to the Framed Routing IP addresses. The first type of terminals are terminals mounted on the CPE, such as a laptop, a desktop, an AGV (Automated Guided Vehicle) device, an AR (Augmented Reality)/VR (Virtual Reality) device, and the like. Information interaction in the LAN is carried out between the first class terminals in the same LAN through the UPF Network element, and the first class terminals can be forwarded through the UPF Network element without passing through DN (Data Network).
