Magnetic-levitation train communication partition switching method and device based on position information and medium

The invention provides a magnetic-levitation train communication partition switching method and device based on position information and a medium. The method comprises the following steps that the position information in the train running process is detected in real time; when it is detected that the train arrives at a first preset position, zone switching preparation is triggered, and reference time and a period of switching invitation are sent to a zone base station controller of a next zone; when the train passes through a second preset position behind the starting point of the overlapped coverage area of the current subarea and the next subarea, subarea switching is started, and the vehicle-mounted base station controller controls switching of the working frequency of the transceiver of the mobile base station so as to prepare to communicate with the next subarea; after a switching invitation signal sent by the subarea base station controller of the next subarea is received, communication connection betwe
