The invention relates to a base station load balancing method and system for a driving test place, and the method comprises the steps that a mobile terminal receives planning information send by a supervision center; the mobile terminal obtains first online information according to the current position information and the planning information, and transmits an online request signal to a first basestation according to the first online information; the first base station transmits an online answer signal to the mobile terminal according to the online request signal, and the two sides build service connection if the first base station can provide a connection service; the mobile terminal requests the supervision center for giving up the connection if the first base station cannot provide theconnection service, and obtains the second online information; the above process is always performed in the same way till the connection with the base station is built. According to the invention, the supervision center performs the planning of the information of a base station which can be connected with a mobile terminal at any coordinate position in a test place, and the planning is updated inreal time, so the method can effectively solve the problems of slow response speed of the base station service and the lower system communication efficiency which are caused by the excessively busyness of the service base station connected with the mobile terminal.
