  • A Handover Algorithm for LTE System based on the Target Cell Pre-Bearer in High-speed Railway Environment
    International Journal of Advancements in Computing Technology, 2012
    Co-Authors: Linlin Luan, Muqing Wu, Yifan Zhang, Ankang Zhang, Chunyan Zhang

    Abstract:

    Abstract This paper evaluates the handover performance of an optimized A3 event handover algorithm of LTE system, which is based on the target cell pre-Bearer Procedure in the high-speed railway (HSR) scenario. The paper introduces this handover algorithm and the handover signaling Procedure based on the target cell pre-Bearer Procedure. These have been designed and implemented in a dynamic system level simulator and have been studied to select different handover parameter sets for HOM (Handover hysteresis margin) and TTT (Timeto-Trigger) in the different velocity interval of the UE (User Equipment) for the high-speed railway simulation scenario. The different HOM and TTT parameters have been simulated in a dynamic system level simulation platform and have been investigated the influence to radio link failure (RLF) via the simulation. The results suggest that this kind of handover algorithm has better handover performance in the velocity internal 250km/h and 350km/h.
