High Altitude Platforms (HAPs) have the prospect of becoming one of the most important communications infrastructures in the near future which can provide either 3G/4G mobile services or Broadband Fixed Wireless Access (BFWA) services. In this paper, the authors propose a novel connection admission control scheme named Rate Transition Area assisted Guaranteed Handover Scheme (GHS-RTA), which utilizes the geographical information, rate transition areas and overlap areas to intelligently decide when to block a new call. This scheme helps avoid possible inter-cell and intra-cell handover failures for HAP communications systems with adaptive modulation and coding in the physical layer.
