[0002] In the traditional satellite transmission process, the satellite connects and communicates with the satellite control platform through the satellite signal ground receiving station, and the data transmitted between the satellite and the satellite control platform includes the status data reported by the satellite and the control data issued by the satellite control platform, etc. , if a dedicated communication line is laid for the transmission of data such as status data and control data, it will cost a lot of laying costs, and also need to increase the maintenance cost of the dedicated communication line, such as maintenance costs such as security and stability
In addition, because low-orbit and medium-orbit satellites have smaller coverage than high-orbit synchronous satellites and are not synchronous with the earth's rotation, a large number of satellite signal ground receiving stations need to be laid on the ground in the future. If each satellite signal ground receiving station Independently laying communication channels with the satellite control platform will also increase construction costs and maintenance costs

The invention discloses a core network-based satellite data link establishment method, device and storage medium, including: when the satellite monitors the wireless signal of the ground signal station of the core network, the satellite sequentially passes through the access management network element and the core of the core network The session management network element of the network sends a data plane session establishment request to the user plane network element of the core network; the user plane network element receives the data plane session establishment request, and establishes the downlink data link from the user plane network element to the satellite according to the data plane session establishment request. link, and send the data plane session establishment response to the satellite through the session management network element; the satellite receives the data plane session establishment response, and establishes an uplink data link according to the data plane session establishment response. The embodiment of the present invention can use the data link of the core network to establish the data link of the satellite, realize the multiplexing of the data link of the core network, thereby reducing the cost of establishing the satellite link, and can be widely used in the field of satellite communication.
