Abstract

There are provided mechanisms for supporting a Circuit Switched (CS) service in a 5G Core Network (5GCN). A method is performed by a wireless device. The method comprises registering with an Access and Mobility Management Function (AMF) of the 5GCN using Non-Access Stratum (NAS) signalling. The method comprises registering, with the 5GCN and using NAS signalling, for at least one CS service, wherein the registering for the at least one CS service is performed in conjunction with registering with the AMF.
