Seamless Handoff Scheme Based on Pre-registration and Pre-authentication for UMTS–WLAN Interworking

Abstract: Interworking issues between Universal Mobile Telecommunication System (UMTS) and Wireless Local Area Network (WLAN) have become a great matter of interest as an increasing number of mobile internet users require broadband wireless access to IP services in the wide area. In this paper, we present a practical UMTS-WLAN interworking architecture based on 3GPP standards and propose a seamless handoff scheme that guarantees low delay and low packet loss during UMTS-WLAN handoff. For low handoff delay, the proposed … Show more

“…The signaling cost can be defined as the total authentication signaling message traffic during a communication session [25]. Since the BS scanning messages and the UE registration are the same for all handovers protocols, our study is focused only on the handover control messages.…”

“…Indeed, recent wireless networks have various characteristics in terms of latency, bandwidth, frequency and coverage. For example, third generation (3G) cellular networks, such as the Universal Mobile Telecommunication System (UMTS) provide low bandwidth and wide coverage [1]. In contrast, wireless local area networks (WLANs) such as IEEE 802.11 and the European high performance radio LAN (HiperLAN) provide high bandwidth and small coverage [2].…”
