Further, in the step B, the specific manner of updating the parameter file and the digest timestamp file according to the comparison result is as follows:
if the comparison result is the same, the file is not updated, if not, the summary timestamp file is modified by the digital summary of the new parameter file and the current timestamp, and the parameter file is updated;
in addition, if the terminal parameter file is updated, the corresponding terminal parameter file timestamp in the terminal version parameter file will also be updated.
Further, the specific manner of step E is: if the comparison result of the time stamps in the step D is the same, the terminal parameter file of the TDMA remote station is not updated; if not, the main TDMA terminal sends a parameter application to the management system, and the management system sends the latest terminal parameter file corresponding to the terminal to the TDMA remote station.
