“…However, only one subscription is needed with a 3G operator or a WLAN service provider, who has roaming agreements to support the interworking (Buddhikot et al, 2003a). A lot of research in the literature considers the scenario in which a 3G subscriber is provided WLAN access via independent WLAN systems.…”

“…Considering the flexibility and interoperability requirement, AAA server is introduced in UMTS (3GPP, 2004b). By means of EAP-AKA, the 3G home AAA server authenticates the UMTS subscribers roaming to a WLAN through the UMTS AKA procedure (Ahmavaara et al, 2003;Buddhikot et al, 2003a;Koien and Haslestad, 2003;Salkintzis, 2004), while EAP-SIM can be used for legacy GSM/GPRS system (Ala-Laurila et al, 2001; Salkintzis et al, 2002). The authentication information and subscription profile can be retrieved from the Home Subscriber Server (HSS) or HLR.…”

“…When MIP is supported in the 3G and WLAN networks, the authentication can also be carried out at the network (IP) layer (Buddhikot et al, 2003a). In the mobile IP mode of cdma2000, PDSN is augmented with Foreign Agent (FA) functionality, while HA is introduced to maintain location information of MSs and forward IP packets to MSs via tunnelling.…”

“…In Buddhikot et al (2003a), it is proposed to authenticate the mobile node via a secured web page for login over a Hypertext Transport Protocol Secured (HTTPS) connection. This type of solution has restricted applications since it requires the support of specific services such as HTTP.…”

“…In the loosely-coupled interworking architectures proposed in Salkintzis et al (2004) and Buddhikot et al (2003a), the MIP approach is used for the mobility across the cellular network and WLANs. Even though the loose coupling allows for the flexibility of implementing different individual mobility management schemes within each network, it has become a trend to apply MIP in 3G networks to pave the way for future all-IP networks.…”

Abstract:The Third Generation (3G) cellular networks provide ubiquitous connectivity but low data rates, whereas Wireless Local Area Networks (WLANs) can offer much higher data rates but only cover smaller geographic areas. Their complementary characteristics make the integration of the two networks a promising trend for next-generation wireless networks. With combined strengths, the integrated networks will provide both wide-area coverage and high-rate data services in hotspots. There are many aspects involved in their interworking, such as mobility, security and Quality of Service (QoS) provisioning. In this paper, we present a survey of most recent interworking mechanisms proposed in the literature, and outline some important open issues to achieve seamless integration.Keywords: 3G/WLAN interworking; tight/loose coupling; mobility management; quality of services; QoS provisioning.
