Abstract: A session management network element determines whether a first communication apparatus and a second communication apparatus have a redundancy functionality, receives a session establishment request message from a first terminal device, to request to establish a first session between the first terminal device and a data network. When both the first communication apparatus and the second communication apparatus have the redundancy functionality, and the first session is a redundant session, selects a first user plane function network element to establish the first session, where the second user plane function network element is configured to establish a second session, the first session is a redundant session of the second session, and the first session and the second session are for communication between the first communication apparatus and the second communication apparatus.
