    One of the essential targets of LTE HetNet is to provide seamless and fast handover from one cell to another to achieve a strict delay requirement while, at the same time, keeping network management as simple as possible. Hence, the decision to trigger a handover is very important in the design of handover process. Handover performance in heterogeneous networks deployments is not as good as in homogenous deployments. The handover triggering is highly depended on the UE speed, which means that as the UE speed changed, the handover triggering time is correspondingly varied. It means high speed user equipment (UE) suffers much higher handover failure rate than low speed UE. Determining a more accurate handover triggering point is a critical issue. Too late handover triggering caused by UE speed change will lead to handover failure. For handover to be successful, it requires to choose handover parameters correctly and optimize their setting. In this paper we proposed a forward handover scheme that allows pico to macro cell handover process to be fast. Because of faster handover procedure we can ensure better RSRP for the user moving at high velocity at the cell edge region.
