Prediction Handover Trigger Scheme for Reducing Handover Latency in Two-Tier Femtocell Networks

Service continuity in two-tier Femtocell networks, especially impaired by the handover latency, remains as a problem to be solved. Motivated by this problems, a Layer 3 prediction handover scheme is proposed, which can be integrated into the User Equipment (UE) part of industry-preferable Mobile-Assisted Network-Controlled Handover (MANCH). In simulations, to evaluate the robustness of the proposed scheme, a module of UEs' movement pattern is designed, considering characteristics of the UE's movement pattern. Results of the performance evaluation show that handover latency of indoor handover UEs can be effectively reduced with high prediction accuracy.
