1. An air and ground network joint invocation system, characterized by comprising:

  • the system comprises an air base station and a ground base station, wherein the downlink frequency spectrum of the air base station is different from the downlink frequency spectrum of the ground base station, and the uplink frequency spectrum of the ground base station comprises the uplink frequency spectrum of the air base station;

    the aerial base station is used for switching from an idle state to an active state when a terminal accesses the aerial base station, and forwarding the aerial activation message to the ground base station associated with the aerial base station;

    the ground base station is used for setting a part of an uplink frequency spectrum of the ground base station, which is overlapped with the uplink frequency spectrum of the air base station, as a forbidden call after receiving the air activation message;

    an FDD LTE network for realizing air and ground cooperation under a frequency division duplex FDD mode;

    the utilization rate of the ground network corresponding to the ground base station is higher than that of the air network corresponding to the air base station.
