Abstract: Provided are a UE migration method, apparatus and system and a storage medium. An NF that establishes a signaling interaction with an active SMF acquires a link state between the NF and the active SMF; the NF sends an SMF failure notification message to a standby SMF in response to determining that the active SMF fails; and the standby SMF migrates a UE to be migrated on the active SMF to the standby SMF according to a received SMF failure notification message. Further provided is a method for restoring UEs on a failed SMF to a standby SMF in batches.
