Abstract
World leading telecom technology manufacturers and network operators have initiated a joint initiative aimed at driving forward the realization of the next generation of high performance mobile broadband networks based on 3GPP LTE/SAE specifications. The motivation of 3GPP LTE/SAE was when it became clear that the future telecommunication systems was clearly IP with everything (the "all-IP" network, AIPN), and that access to the 3GPP network would ultimately be not only via UTRAN or GERAN but by WiFi, WiMAX, or even wired technologies. In this paper, we propose security mechanisms for secure fast handover during Inter-RAT handover, particularly handover between 3GPP and non-3GPP networks. This paper highlights the possibility and mechanism for security context transfer during Inter-RAT handover between 3GPP and trusted non-3GPP networks and also a pre-authentication mechanism for handover between 3GPP and un-trusted non-3GPP networks.
