To improve the quality of indoor wireless communication
the femtocell begins to be deployed in different indoor wireless communication scenarios.In the densely deployed femtocell network
when users handover from the macrocell to the femtocell
the multiple RSRP from different femtocell seriously affect the accuracy of the handover process.To solve above problems
the idea of femtocell cluster was proposed to improve the handover accuracy and reduce the unnecessary handover.In addition
a cache handover strategy was proposed to improve the efficiency of handover from macrocell to femtocell.Simulation results verify the proposed algorithms and strategies.
