Abstract
The benefits brought about by 3G networks such as UMTS, it is increasingly desirable to integrate 3G
networks with WiMAX.. WiMAX is used to extend 3G networks at certain locations in order to provide improved
services and address QoS issues. To achieve a beneficial vertical handover in a network, an algorithm that departs from
the conventional RF based algorithm is necessary. An attempt is made in this study to provide an algorithm which aims
to utilize location information stored in a WiMAX coverage database, and the location service entities of UTRAN as
defined by 3GPP to determine a valuable/beneficial vertical handover between UMTS and WiMAX. RF based
conventional downward vertical handovers can be inefficient and waste of resources. This study aims to correct the
lapses associated with conventional RF based vertical handover across heterogeneous network.
