description The invention belongs to the field of 5G air interface time service, and discloses a 5G base station high-precision time service method and system based on satellite and 5G air interface fusion. A receiver is installed in a 5G base station, and the one-way time service time of a Beidou system is obtained. And meanwhile, the 5G base station receives a time signal sent by a 5G server side, and obtains a deviation value of two times. And a deviation calibration value model is established, and model parameters are obtained. And the time deviation value and the model parameters are loaded to a 5G wireless signal end, and sent to a user. The user obtains two types of information, including 5G air interface time information and a time deviation value. And when the 5G base station can receive a satellite signal, the 5G air interface time information is corrected, and 5G air interface user time service is obtained. And when the 5G base station cannot receive the satellite information, a time deviation calibration valu
