Abstract

High speed rail has been developed rapidly in recent years. The passengers traveled by trains demand for higher data rate and service continuity in order for them to access the Internet. The realization to provide reliable communication for the users in high speed mobility is challenging due to the frequent request for handover since the trains moving in high speed which resulting heavy overhead implementation. Since the User Equipment (UE) in trains communicates directly to the outside of the Base Station (BS), it reduced handover successful rate and hence, degraded the service quality.  This research identified the system parameters to improve handover performance in high speed railway network. Moreover, mathematical equation has been derived by integrating the information of train speed and time traveled across the cell. This research has improved handover performances by reducing the probability of drop call rate and increasing the number of handover successful rate.
