Abstract:
The invention relates to methods and devices for enabling relocation of Access and Mobility Management Functions (AMFs). In an aspect of the invention a method performed by a Non-3rd Generation Partnership Project (3GPP) Interworking Function (14, N3IWF) enabling a wireless communication device (10) to attach to a core network (100) over non-3GPP access, to facilitate re-location of the wireless communication device (10) from an Access and Mobility Management Function (13, AMF) currently serving the wireless communication device (10) over non-3GPP access to the core network (100), to a target AMF (21) which is to serve the wireless communication device (10) over 3GPP access to the core network (100). The method comprises receiving (S119a), from the target AMF (21), a request to redirect any further signalling of the wireless communication device (10) from the currently serving AMF (13) to the target AMF (21); and redirecting any signalling of the wireless communication device (10) to the target AMF (21).
