Abstract
Methods and systems taught herein provide for authentication information for authenticating a user terminal to be shared between a network entity that supports IMS-AKA authentication of the user terminal and a network entity that supports GBA-AKA authentication of the user terminal. Sharing authentication information between these entities allows all or part of the authentication information generated for IMS-AKA authentication of the user terminal to be used subsequently for GBA-AKA authentication of the user terminal, or vice versa.
