摘要：

HetNets can enhance of LTE performance in many respects including the system capacity and network coverage. Pico-cell based access networks are increasingly seen as a promising solution for the growing mobility demands. More careful management of mobility and handover (HO) might be required in HetNets compared to homogeneous networks where all nodes require the same transmission power. In this article, we provide a technical overview of mobility and HO management for HetNets in LTE-A. Moreover, mobility performance of heterogeneous network is studied in terms of success handover probability in deployment of macro-cell and pico-cell. We characterize the handover success rate in a 3GPP heterogeneous network scenario as a function of relevant system parameters such as time-to-trigger, user equipment velocity, etc. It plays a key role in practical systems. © 2015 by Binary Information Press.
