description Provided are methods and related devices for implementing disaster recovery. According to a method, in a case where a main Session Management Function (SMF) fails, a backup SMF sends a first request to a User Plane Function (UPF), wherein the first request carries a node identifier (Node ID) of the main SMF, a Node ID of the backup SMF, and a Common Session endpoint Identifier List (CSIDLIST) corresponding to the backup SMF; and the first request is used for notifying the UPF that the main SMF fails and a session or sessions in the CSIDLIST corresponding to the backup SMF is/are to be taken over by the backup SMF, so that the UPF subsequently interacts with the backup SMF for the session or sessions in the CSIDLIST corresponding to the backup SMF.
