The invention relates to an air-ground communication network architecture, a ground base station and a base station array antenna switching method, and belongs to the field of aviation communication. The method comprises the following steps: a base station monitors a wireless link state of a current antenna serving as a working antenna; if the wireless link state is abnormal, the base station judges that aircraft position information sent by the airborne end can be received in real time; if the aircraft position information is not received, the base station polls four nearest antennas around the current antenna, and at the same time, a switching instruction is sent to a base station access controller AC; and if the target antenna capable of communicating with the airborne end is polled, the base station takes the target antenna as a new working antenna and sends a switching-back instruction to the AC.

    本发明涉及空地通信网络架构、地面基站及基站阵列天线切换方法,属于航空通信领域。该方法包括:基站监控作为工作天线的当前天线的无线链路状态;若无线链路状态异常,基站判断能实时接收到机载端发送的飞机位置信息;若接收不到飞机位置信息,则基站轮询当前天线周围距离最近的4个天线,与此同时,向基站接入控制器AC发送切换指令;若轮询到可与机载端通信的目标天线,则基站将目标天线作为新的工作天线,并向AC发送切回指令。
