Abstract
A primary authentication procedure is triggered to derive an authentication key for a home network. The authentication key may be used for interworking between network types. For example, a home network primary authentication mechanism may be triggered for interworking from Evolved Packet System (EPS) to 5GS. When a user equipment (UE) moves between network types, the security context and authentication may be different or incompatible. For example, an authentication key may be missing, which may be needed for authentication in one of the network types. Authentication key support may be determined and registration/authentication may vary based on that support. When there is no support for the authentication key, a reauthentication process may be performed.
