The invention provides a realization method and a device for an action-based satellite mobile communication gateway station. The realization method comprises: air interface link of the gateway station for communicating with the satellite uses a user link of a satellite mobile communication system, and the gateway station accesses a ground core network through a broadband wireless access mode; the gateway station initiates a registration process to the satellite and the ground core network after starting up and the satellite identifies the gateway station as a gateway station backhaul device after the registration of the satellite is succeeded; for the downlink of the satellite, the satellite transmits the data pack which is needed to be transponded to the gateway station through the user link; the base station transponds the data pack to the ground core network through the wireless broadband base station; for the satellite uplink, the ground core networks transmits the data pack which is ...
