Abstract: In this paper, enhanced mechanisms of interworking (interoperability) between High Speed Downlink Packet Access (HSDPA) as 3.5G cellular network and HIPERLAN2 (H2) as wireless LAN are proposed and their performances are evaluated by system level simulation. Two cost-based techniques: Initial User Assignment (IUA) and Inter-System Handover (ISH) are selected, covering all possible assignment and handover key factors, to represent the interworking criteria. Results show a considerable enhancement in terms of selected performance metrics such as blocking and dropping probabilities. Weight values readjustments are also tested to highlight the critical key factors affecting interworking mechanisms.
Keywords: HSDPA; HIPERLAN2; interworking mechanisms; initial user assignment; inter-system handover; interoperability; 3.5G cellular networks; wireless LANs; WLANs; local area networks; simulation; blocking probability; dropping probability.
