1. A method for selecting one or more network slices assignable for a user equipment (UE) within a telecommunications network, the method comprising:
receiving a network slice selection request from a first Access and Mobility Management Function (AMF);
determining, based on the network slice selection request, selection data specifying at least one UE specific parameter affecting network slice selection;
selecting, based on the selection data, one or more network slices assignable for the UE;
determining whether the one or more network slices assignable for the UE are supported by the first AMF, and upon determining the one or more network slices assignable for the UE are not supported by the first AMF, determining a second AMF supporting the one or more network slices assignable for the UE; and
transmitting to the first AMF an authorized network slice selection assistance information (NSSAI) representing the one or more network slices assignable for the UE and information indicating the second AMF if the one or more network slices assignable for the UE are not supported by the first AMF.
