Abstract
In heterogeneous networks (HetNet), it is an important issue to determine a suitable access network for call request to support seamless service and stable connectivity. For moving user equipment (UE), when and how to select a appropriate cell is more challenging. Since relatively long handover (HO) interruption time occurs due to the frequent HO, they experience significantly degraded data rate. Therefore, we propose dwell-time based multi-traffic cell selection method with carrier aggregation (CA) to reduce the effect of HO interruption time. Dwell time means the time UE stays in a cell. Using the dwell-time considered cell selection method, we expect increase average UE throughput by declining the interruption time. Simulation results show that our proposed scheme improve the UE experienced data rate.
