Abstract

The Heterogeneous Network (HetNet) based ultra-dense network is the possible solution to cope up with the exponential growth in data traffic. The HetNet deployment provides benefits of load balancing, better connectivity and higher data rate to the users. However, the diversity in transmit power results in downlink (DL)/uplink (UL) imbalance and poses a serious issue in mobility management. Adoption of DL/UL decoupled (DUDe) handover (HO) method where DL and UL HO occurs separately which could possibly improve the user’s quality of service and network performance. The control parameters involved in this DUDe HO procedure should be properly configured to achieve the expected performance. In this work, simulation analysis has been carried out to explore the dependency of these control parameters on various factors such as Inter-Site-Distance (ISD), velocity and offloading. The analytical results provide interesting insights about the control parameter configuration in decoupled wireless connection. From the analysis results, measurement configuration strategy has been developed to configure the HCP in decoupled HO method. The results show the proposed method achieves increase in dwell time when compared to the legacy coupled HO method.
