Technical Problem
[0013]本发明实施例提供的UE迁移方法、装置、系统及存储介质，主要解决的技术问题是相关技术中在SMF发生故障时，造成PDU会话失效，导致UE的上下行数据都将无法正常投递
Benefits of technology
[0043]根据本发明实施例提供的UE迁移方法、装置、系统及存储介质，NF对NF与主用SMF之间的链路状态进行获取，NF为与SMF建立信令交互的非SMF的NF，当NF在确定主用SMF发生故障时，NF向备用SMF发送SMF故障通知消息，然后备用SMF根据接收到的SMF故障通知消息将主用SMF上的UE迁移到自身上，能有效解决因SMF故障造成PDU会话失效，进而导致UE的上下行数据无法正常投递的问题；并且，本发明也提供了一种将故障SMF上的UE批量恢复到备用SMF上的方法，能有效节省SMF故障恢复的总体时间。

Abstract
The application provides a UE migration method, device, system and storage medium. An NF which establishes signaling interaction with an SMF acquires the link state between the NF and a primary SMF. When the NF determines that the primary SMF fails, the NF sends an SMF failure notification message to a backup SMF. Then, the backup SMF migrates the UE to be migrated on the primary SMF to the backup SMF according to the received SMF failure notification message, so that the problem that the PDU session is invalid due to the SMF failure and the uplink and downlink data of the UE cannot be normally delivered can be effectively solved. Furthermore, the application also provides a method for batch restoring the UE on the failed SMF to the backup SMF, so that the overall time for recovering the SMF failure can be effectively saved.
