Abstract

Embodiments describing methods performed by a system comprising Network functions including at least a Session Management Function and a User Plane Function for performing a UPF re-anchoring for an application triggered at a User Equipment over an established Packet Data Unit (PDU) Session, where when the system receives the initial trigger for a service triggered by the application (e.g., a DNS request or an application level request), a determination is made by the system based on the information related to the application that re-anchoring of the UPF for that application into a local UPF closer to the UE is required. When re-anchoring of the UPF is successful, the initial trigger is discarded, and the UE is instructed to establish a new PDU session over the local UPF for that application.
