Mobility management protocols use various layers of the protocols for the past years. This protocol uses various handoff for various types of applications. The aim of this paper is to investigate handoff concepts in wireless communication. Mobility is an important feature of wireless cellular systems. As a mobile subscriber move between various radio networks, handoff/handover is needed to continue the active process. The continuation of an active call is one of the most important quality measurements in wireless mobile cellular systems. The handover process enables a mobile cellular system to provide such a facility by transferring an active call from one cell to another cell. This paper represents the approaches, types, and techniques used for transferring an ongoing call from the current cell to the next adjacent cell.
