A location-aware secure interworking architecture between 3GPP and WLAN systems

초록

Location-aware computing is widely discussed to be one attractor of the future ubiquitous networks for intelligent home and telematics services. Apart from technical difficulties in providing accurate position information there is also a lack of a clearly defined framework how to create innovative and secure services using location information. In this paper, we identify QoS, interworking and security problems in location-aware computing. We propose a number of concepts and infrastructures for location-aware security services including micro and macro mobility management in ubiquitous home networks and heterogeneous wireless networks. We further explain how the proposed approach can be applied to seamless secure interworking among wireless LANs and 3G, 4G cellular systems, Our approach might be helpful in the discussion for the frameworks especially highlighting evolutionary steps for the next ubiquitous networks.
