An Architecture for UMTS-WIMAX Interworking

One motivation of Next Generation Networks is the ubiquitous wireless access abilities which provide the automatic handovers for any moving devices in the heterogeneous networks combining different access technologies. In this paper, we present a possible UMTS-WIMAX interworking architecture based on the 3GPP standards and propose the seamless inter-system handover scheme which enables the service continuity with low handover latency and packet loss.
