摘要： The embodiments herein relate to methods and functions for handling a user equipment, UE, that is in an idle state with respect to at least one access type e.g., 3GPP access or non-3GPP access. According to an embodiment, an Access and mobility Management Function, AMF, receives from a Session Management Function, SMF, a request to establish User Plane, UP, for a UE's PDU session, wherein the request comprises information indicating a preferred access type. According to another embodiment, an SMF receives from a User Plane Function, UPF, a notification that the UPF is buffering downlink data for a UE's PDU sessions; and in response to the notification sent by the UPF, the SMF sends to an AMF, serving the UE, a request to establish User Plane, UP, for the PDU session, wherein the request comprises information indicating a preferred access type. According to a further embodiment, a UE receives a page message, wherein the page message is configured to trigger the UE to make a Service Request, SR, over non-3GPP access; and the UE, in response to receiving the page message, performs a Service Request procedure over non-3GPP access if non-3GPP access is available.
