Abstract
During handover of a cellular terminal from a wide area cellular network to a base station, authentication messages are relayed between the base station and the wide area cellular network via the cellular terminal. Communications between the cellular terminal and the wire telephone network via the base station are prevented until after authentication takes place. Accordingly, the cellular terminal relays authentication messages between the base station and the wide area cellular network. Use of the wire telephone network for authentication between the cellular terminal and the base station is avoided. Secure handover is thereby provided without incurring excess overhead to the system and without adding unnecessary wire network charges to the cellular terminal user.
