Abstract
A method at an Access and mobility Management Function (AMF) for facilitating a Protocol Data Unit (PDU) session procedure for a User Equipment (UE) in a 5th Generation System (5GS) network, wherein the 5GS network is interworking with an Evolved Packet System (EPS) network, and a Packet Data Network Gateway Control plane Function+Session Management Function (PGW-C+SMF) supporting the interworking is selected for managing the PDU session. The method comprises determining whether the PDU session supports interworking with the EPS network, based on at least one of a capability of the UE and a subscription data of the UE; and sending an indication which indicates whether the PDU session supports interworking with the EPS network to the PGW-C+SMF.
