ZEUS: Handover algorithm for 5G to achieve zero handover failure

In 5G, the required target for interruption time during a handover (HO) is 0 ms. However, when failure (HOF) occurs, increases significantly to more than hundreds of milliseconds. Therefore, fulfill requirement in as many scenarios possible, we need minimize HOF rate close zero possible. 3GPP has recently introduced conditional HO (CHO) improve mobility robustness. this study, propose “ZEro with Unforced and automatic time-to-execute Scaling” (ZEUS) algorithm optimize parameters easily CHO. Analysis simulation results demonstrate that ZEUS can achieve without increasing ping-pong rate. These two metrics are typically used assess an because there tradeoff between them. With introduction CHO, which solves tradeoff, only these insufficient anymore. evaluate optimality algorithm, define new integrated performance metric, mobility-aware average effective spectral efficiency (MASE). The show provides higher MASE LTE other CHO variants.
