5. A method performed by a Non-3rd Generation Partnership Project (3GPP) Interworking Function (N3IWF) enabling a wireless communication device (WCD) to attach to a core network over non-3GPP access, to facilitate re-location of the wireless communication device from a source Access and Mobility Management Function (AMF) currently serving the WCD over non-3GPP access to a target AMF which is to serve the WCD over 3GPP access, comprising:
receiving, from the target AMF, a redirect request to redirect signalling of the WCD from the source AMF currently serving the WCD to the target AMF;
after receiving the redirect request, receiving signalling transmitted by the WCD; and
as a result of receiving the redirect request transmitted by the target AMF, transmitting the received signalling to the target AMF rather than the source AMF.
