Location Aware Mobility Assisted Services for Heterogeneous Wireless Technologies

Abstract — Mobile user tracking and seamless service conti-nuity in heterogeneous network environments represent an issue, especially when users move from outdoor to indoor environments, and vice versa. Mobile terminals with these properties allow providers to enable new services. In this paper, a location aware mobility-assisted technique for both indoor and outdoor environments is presented. The technique provides local position-ing service and non-homogeneous connectivity management for UMTS, IEEE 802.11, and GPS networks. Index Terms — Local positioning, vertical handover, mobility
