摘要: Femtocell is an emerging technology aiming for a better indoor coverage. Due to its low costs, high grade of service, promotion fixed-mobile convergence (FMC) and no change core network, it has drawn close attention from the standardization organizations industrial field. In two-hierarchy networks composed traditional macro cellular embedded femtocell hotspots, moving mobiles will face up continual handovers when they pass along buildings. this paper, handover algorithms considering signal strength velocity are proposed using mathematics concept "set". Different methods discussed simulated. The results show that can obviously cut down unnecessary compared with conventional soft on same level limit. What's more, throughput speed total base station increased.
