N2 - The first wave of 5G networks is already coming and ready to affect our life. One of the main parts of mobile networks is mobility management that provides seamless mobility from the current cell to the neighbor. 3GPP Rel.15 teams developed the conditional handover for a single connection to improve mobility robustness. The prepared multiple target cells in a preparation step are an enhancement of the conditional handover scheme. Also, this enhancement improves performance related to the user’s mobility in the mobile network. In this paper, we present the enhanced conditional handover that can provide a reduction of handover failures. But, the increased signaling overhead and ping-pong handovers are the main problems. From simulation results, our proposal provides the reduced measurement reports and improved handover performance compared with the baseline handovers in the heterogeneous networks.
