Abstract
A network management method and a controller are provided. Elastic scaling of an in-network packet data network IN-PDN is implemented when UE is migrated or detached. In addition, service continuity in a local network of the UE can still be ensured when the UE is migrated or detached, and an IN-PDN resource that is no longer used is reclaimed in time, thereby avoiding a waste of the IN-PDN resource.
