WIPO Patent Application WO/2022/247875
Kind Code:
A1
Abstract:
Disclosed in the present application are a method, apparatus and system for establishing a connection. According to the solution provided by embodiments of the present application, an SMF sends session information to a TD-SMF, the session information comprising a first tunnel endpoint identifier of a PSA-UPF, an IP address of a terminal, and an IP network segment routing mask corresponding to the IP address; the TD-SMF sends these session information to a TD-UPF, so that the TD-UPF publishes the IP address and the IP network segment routing mask of the terminal to a network and establishes a downlink tunnel with the PSA-UPF, and thus the TD-UPF can receive the data of the terminal from the network and send same to the PSA-UPF; and then the TD-SMF sends a second tunnel endpoint identifier of the TD-UPF to the SMF, and the SMF sends the second tunnel endpoint identifier to the PSA-UPF, so that the PSA-UPF can establish an uplink tunnel with the TD-UPF.
