Abstract(in English) | The use of small cell deployments in heterogeneous networks (HetNet) environments is considered a promising strategy to cope with the explosion in mobile traffic. In the deployments, there is a concern that the large number of small cells causes the signalling load on the network nodes to increase due to frequent handovers (HOs) and mobility robustness to be degraded due to increased handover failures (HOFs) and radio link failures (RLFs). To examine these impacts caused by the introduction of small cells, in this paper, we evaluate mobility performance on small cell deployments in LTE-Advanced systems. The simulation results show that the number of HOs occurs at most 3.3 times compared to a macro cell-only deployment even in the case where there are 20 small cells per macro cell. The results also show that the HOF rate increases about 10 times compared to the macro-only case, and some technique to eliminate these HOFs should be applied in the case of large number of small cells. |
