CONCLUDING REMARKS

We have carried out a first comprehensive measurement study that uncovers 5G mobility management. We conduct extensive drive tests for 6,200 km+, covering both urban and rural areas in the U.S. Our measurement findings offer deep insights into the performance, energy, cross-technology impact, upper-layer implications, and operational issues of 5G HOs. We design a holistic HO prediction system to improve application QoE during mobility. Our research also identifies key research directions on improving 5G mobility management. We have released our datasets to the research community.
