A Novel Decision Algorithm for Vertical Handoff between UMTS and WiMAX
Journal Title: Scholars Journal of Engineering and Technology - Year 2013, Vol 1, Issue 4
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.
