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 (GPP) Interworking Function (, NIWF) enabling a wireless communication device () to attach to a core network () over non-GPP access, to facilitate re-location of the wireless communication device () from an Access and Mobility Management Function (, AMF) currently serving the wireless communication device () over non-GPP access to the core network (), to a target AMF () which is to serve the wireless communication device () overGPP access to the core network (). The method comprises receiving (S), from the target AMF (), a request to redirect any further signalling of the wireless communication device () from the currently serving AMF () to the target AMF (); and redirecting any signalling of the wireless communication device () to the target AMF ().
