Mobility robustness self-organizing network handover scheme for LTE-Advanced

摘要

In this paper, we present a new adaptive handover algorithm for LTE-Advanced system. This algorithm ensures the User Equipment (UE) requirements and the Quality of Service (QoS) expectations. The proposed algorithm relies on the dynamic adjustment of the handover parameters settings based on the velocity of the UE. In order to reduce the conflict between mobility robustness optimization and load balancing the handover decision takes into consideration the channel conditions and the load of the neighbor Evolved Nodes B (eNBs). The simulation results show the superiority of our proposed algorithm in terms of throughput and handover failure rate.
