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.

Abstract: The present disclosure relates to a user data processing apparatus and method, and a system. In the user data processing apparatus disclosure, an interface management unit receives user data; at least two service units process the user data, where the at least two service units include a session unit and at least one of a bearer unit, a service flow unit, or a content unit; the interface management unit determines the session unit configured to process the user data, and sends the received user data to the determined session unit; and the session unit determines another service unit configured to process the user data. After receiving the user data, the GW-U determines the service unit configured to process the user data, and processes the user data by using the service unit determined by the GW-U. This improves processing flexibility of the GW-U.
