Handover Scheme Considering for Signaling Time in Mobile Networks

In the wireless communication systems of the next generation, the hard handover may frequently occur between the existing 2G(2nd generation) and the 3G(3rd generation). When it occurs between the 2G and the 3G, the call setup procedure will be added to MT(Mobile Terminal), the relay bases in 2G and 3G, and the switches. It causes total time to handle the handover to increase. Therefore, the forced termination probability may be increased since relative time decreases. In this paper, we propose a method to decrease the forced termination. The method execute the handover procedure with speed and direction of the MT preestimated in the inner cell when MT enters the boundary cell.
