1. A method performed by an Access and mobility Management Function (AMF), the method comprising:
the AMF receiving from a Session Management Function (SMF) a request to establish User Plane (UP) for a user equipment's (UE's) protocol data unit (PDU) session, wherein the request comprises information indicating an access type; and
in response to the request to establish UP for the UE's PDU session, the AMF performing the steps of:
determining that a condition is satisfied, wherein determining that the condition is satisfied comprises determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access; and
as a result of determining that the condition is satisfied, initiating paging of the UE by the 3GPP access.
