The advent of 5G and other technological advancements will provide enhanced mobile broadband, significantly reduced latency in communications, and the accommodation of larger mobile devices. This implies that, in the case of users with exceptionally fast speeds, it is imperative to ensure a seamless transition between cellular networks. The effective management of dense networks is crucial due to the significant presence of a multitude of mobile devices. In addition, the time-to-trigger(TTT) and hysteresis margins, which significantly impact the delay in handover and overall throughput, necessitate the need for dynamic adaptability. In this paper, we present a novel approach for addressing the issue of mobility management in the context of 5G. Hence, the objective of this research is to ascertain the optimal target cell for utilization as an advanced 5G Node B in order to address this issue. The selection of a target cell in this approach is determined by various parameters, including as the quality of the received signal, the power of the received signal, and the uplink signal-to-interference-plus-noise ratio (SINR). After the selection of a 5G node, user equipment (UE) within the designated cell will initiate a handover (HO) process to connect with the most optimal 5G node available. The simulation results demonstrate an improvement in the performance indicators of the anticipated handover scheme, namely in terms of handover failures, handover ping-pong, and packet loss.
