Abstract:
Cooperation amongst heterogeneous mobile radio systems will be an indispensable feature of 'beyond 3G'. One key mechanism thereby serving as enabling technique for system integration will be the Vertical HandOver (VHO) between different radio networks. Optimal handover control thereby is very important for which the present paper investigates a new algorithm for accurate VHO trigger generation. Taking the own position as input, mapping with location-based measurements from other stations is accomplished to decide for heterogeneous system coverage. Special interest thereby is laid on the fact that localization techniques inherently suffer from imprecision. Accurate trigger generation hence needs to overcome the impact of erroneous position information.
