摘要：Handover mechanism is extremely important in cellular network because mobility is the distinct feature of wireless mobile cellular system. When a mobile subscriber moves between different radio networks while using network, a handover process is needed. The continuation of an active call is one of the most important qualitative featurein cellular systems. In this paper we aim to present an overview of handover, type of handover, Handover Detection, purpose of handover, handover in GSM and WIMAX. Handover is a process in telecommunication and mobile communications in which a connected cellular call or a data session is transferred from one cell site (base station) to another without disconnecting the data session or call.There are two type of handover: Hard handover and soft handover. The handover in which the connection to the source is broken before the connection to the target is made is called hard handover. This is called break-before-make.
