Analysis of Handover Trigger Scheme Based on Distance for LTE High-speed Railway Networks
Abstract: In high-speed
railway environment, frequent handovers and high handover failure probabilityresult
in serious communication interruptions and call drops, which become pressing
problem to be solved. Alternative reference point based handover scheme can be
an applicative solution for high-speed rail. This paper analyzes the impact of
handover location on the handover performance. And numerical analysis is utilized
to give a method to determine the distance from the serving eNodeB and the
adjacent one to themobile terminal when handover is triggered. Handover failure
probability is used as criteria for performance. Simulation results show that
the proposed scheme has a better performance than typical event based scheme in
high speed environment.
