Abstract: A system and method of providing quality of service (QoS) control for a specific user equipment (UE) in a slice. The system and method include receiving, by a Session Management Function (SMF) from an Access and Mobility Management Function (AMF), a request for a quality of service (QoS) flow for a wireless communication device; determining, by the SMF responsive to receiving the request, a flow bit rate for the QoS flow; and transmitting, by the SMF to a repository through a Unified Data Management (UDM), a message causing the UDM to update a total flow bit rate in use according to the flow bit rate.

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.
