Abstract
Re-anchoring with Session Management Function (SMF) re-selection is disclosed herein. According to some embodiments, if, for an existing User Equipment (UE) Packet Data Unit (PDU) session, an SMF determines that the current PDU Session Anchor (PSA) for the UE PDU Session is to be relocated and further determines that relocation involves an SMF re-selection, then the SMF initiates re-establishment of the PDU session. During re-establishment, the SMF conveys to an Access and Mobility Management Function (AMF) Edge Computing (EC) context information relevant for the new PDU session. The AMF in some embodiments may use some of this information related to the location of the PSA (DNAI) to select the new SMF, and passes this information to the selected SMF for the new PDU session. Based on the information received, the new SMF in some embodiments establishes the new PDU session and selects and configures the PSA(s) for the new session.
