This paper investigates the application of graph theory solutions for cell handover procedures in 6G integrated terrestrial and non-terrestrial networks, specifically focusing on aircraft communications. The highly dynamic aerospace environment poses challenges for achieving seamless communications and efficient handovers between integrated base stations. Traditional handover management solutions primarily cater to terrestrial networks serving ground users' mobility. However, they are ill-suited for the frequent and unavoidable handovers encountered in aerospace scenarios. These conventional methods rely on reactive approaches, triggered by periodic channel quality measurement reports. When channel quality degrades, a handover procedure is initiated. Unfortunately, in high-speed environments where aircraft rapidly traverse base station cover-age areas, these reports generate numerous handover signals. This not only consumes network capacity but also increases communication latency during reconnection. To address these issues, we propose a proactive approach. By scheduling handover processes based on the best-matched base stations for aircraft, we aim to minimise latency and maintain link availability. Additionally, our strategy involves identifying reliable alternative base stations in case of handover failure.
