The terminal device, the first relay, and the second relay can perform relay service discovery to obtain relay service discovery information, and the network device can also perform relay service discovery to obtain relay service discovery information. The forwarding relationship information is the topology information between the terminal device, the first relay, and the second relay.

[0059] For example, Figure 3 A schematic diagram of node connection relationship in an embodiment of the present disclosure is shown as follows: Figure 3 As shown, the terminal device 39 communicates directly with the second relay 31, the terminal device 38 communicates with the second relay 31 through the first relay 35, the first relay 36 and the first relay 33 in sequence, the terminal device 37 communicates with the second relay 31 through the first relay 34, the first relay 34 can know that the received user plane data comes from the terminal device 37 according to the topology information, and forwards the user plane data from the terminal device 37 to the second relay 31, the terminal device 38 can know that its own user plane data is forwarded to the first relay 35 according to the topology information, the first relay 35 can know that the received user plane data comes from the terminal device 38 according to the topology information, and can know that the user plane data from the terminal device 38 is forwarded to the first relay 36 according to the topology information, the first relay 36 can know that the user plane data received from the first relay 35 comes from the terminal device 38 according to the topology information, and forwards the user plane data from the terminal device 38 to the first relay 33 according to the topology information, and the first relay 33 forwards the user plane data from the terminal device 38 to the second relay 31 according to the topology information.

[0063] S202. Construct a filtering correspondence table for each node based on the user plane data characteristic information of each node. The filtering correspondence table is used to represent the correspondence between the user plane data characteristic information of each node and the processing strategy of the user plane function UPF network element corresponding to each node, so that the UPF network element corresponding to each node forwards the received user plane data or performs communication statistics.

[0064] Among them, different user plane data characteristic information corresponds to different processing strategies. The filtering correspondence table is preset on the SMF network element or the intermediate session management function I-SMF network element.
