Handover in Universal Mobile Technology System

This paper is concern about the study of universal mobile technology system (UMTS) and handovers. CDMA cellular network support soft handover which guarantees the continuity of wireless service and enhance communication quality. Handover means transfer of user connection from one radio channel to another. Cellular network performance depends upon soft handover. Soft handover is that in which channel in the resource cell is retained and used for a while in parallel with channel in target cell. The main goal of this paper is to show that soft handover probability can be calculated with threshold value.
