摘要： In embodiments, a session management device includes at least one transceiver, and at least one processor coupled to the at least one transceiver. The at least one processor is configured to obtain prediction information for a residence time of a user equipment (UE) per a service area of each user plane function (UPF), based on mobility information of the UE. The at least one processor is configured to identify a packet data unit (PDU) session anchor (PSA) UPF for the UE based on the prediction information. The at least one processor is configured to, based on identifying an event according to a movement of the UE, identify whether a UPF corresponding to the service area in which the UE is located is the PSA UPF for the UE. The at least one processor is configured to, based on identifying that the UPF is the PSA UPF for the UE, perform a PSA change to the UPF.
