| As we know, hard handover scheme is adopted for LTE systems in recent years. In order to improve the performance of the overall system, L3-filter, hysteresis, and time-to-trigger window are investigated. In this paper, we propose a new mechanism with an adaptive time to trigger window mechanism to overcome the ping-pong effects and improve the capacity of the whole system. In our simulation, the new mechanism shows less number of handovers, and reduces the number of ping-pong handovers to some extent. To decrease the complexity, our main subject is intra-frequency handover. |
