This invention relates to the field of wireless communication network optimization technology, specifically a three-dimensional communication coverage method that jointly optimizes the downtilt angle of ground base stations and the deployment location of airborne base stations. Based on an integrated air-ground network, this method designs a two-layer optimization architecture for network optimization. By handling the location selection of airborne base stations and the adjustment of antenna tilt angles of ground base stations separately, it avoids strong coupling between discrete and continuous variables, thereby preventing superlinear expansion of the solution space. Simultaneously, by introducing SPSA simulated gradient technology and the ZO-Adam optimization algorithm, it overcomes the non-smoothness and non-convexity problems of the system's spectral efficiency function, ensuring the stability and convergence of the optimization process. Furthermore, the two-layer optimization architecture effectively alleviates the path dependency problem of greedy algorithms, achieving a balance between global search and timeliness.
