The method enables an optimized authentication procedure during handover form an existing system to a new system by using the existing system access keys. The user equipment that is accessing the new system receives a temporary ID during handover preparation which enables the user equipment to perform a fast re-authentication. The method uses existing system access keys to derive system access keys for the new network.
