This invention belongs to the field of mobile communication technology and discloses a service flow scheduling method for high-speed rail millimeter-wave communication scenarios assisted by unmanned aerial vehicles (UAVs). By configuring system parameters such as node location and link parameters, it acquires information such as mobile relay location, candidate link status, and service requirements in real time. It calculates the propagation distance based on the node and mobile relay locations, and uses link parameters to obtain the average load per time slot within a frame. Then, it calculates the minimum number of time slots required for each mobile relay to complete the service through candidate links. Links exceeding the remaining budget of the resource pool are then eliminated to form a feasible candidate set. This scheme can accurately select effective links, avoid resource conflicts and underutilization, and ensure reasonable resource allocation. Based on a scoring system, it selects the optimal link and dynamically updates the candidate set, taking into account both service priority and starvation status. This avoids the problem of high-priority services being squeezed out and weak link services being starved. Furthermore, frame-level cyclic scheduling reduces algorithm complexity and meets the real-time scheduling requirements of high-speed rail scenarios.
