Handover Study Concerning Mobility in the Two-Hierarchy Network

Free registration required

Executive Summary

Femtocell is an emerging technology aiming for a better indoor coverage. Due to its low costs, high grade of service, promotion of Fixed-Mobile Convergence (FMC) and no change of core network, it has drawn close attention from the standardization organizations and the industrial field. In the two-hierarchy networks composed of traditional macro cellular networks and the embedded femtocell hotspots, moving mobiles will face up to the continual handovers when they pass along buildings. In this paper, handover algorithms considering signal strength and velocity are proposed using the mathematics concept of "Set".
