Titel / Title: Location-aware Decision Algorithm For Handover Across Heterogeneous Wireless Network
Abstrakt Abstract:

Vertical handover is the processes that switch a mobile node from one technology to another in order to maintain a communication in a network. Heterogeneous Networks are two Networks whose entities support different technologies. Because of the benefits brought about by 3G networks such UMTS, it is increasingly desirable to integrate 3G networks with WLAN. WLAN is a low coverage, high speed network compared to 3G networks. Consequently, WLAN 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 such algorithm which aims to utilize location information stored in a WLAN coverage database, and the location service entities of UTRAN as defined by 3GPP to determine a valuable/beneficial vertical handover between UMTS and WLAN. RF based conventional downward vertical handovers can be inefficient and wastes resources. This study aims to correct the lapses associated with conventional RF based vertical handover across heterogeneous network.
