And when the errors of the position coordinates are within a preset error range, determining the position information according to the position coordinates.

When the errors of the position coordinates are not within the preset error range, the number of the target access devices is increased by adjusting the preset power schedule of at least one access device 4 in the current area (for example, increasing the transmission power in the preset power schedule of the at least one access device 4), the signal information and the position data of the target access devices are acquired according to the preset time interval, and the position coordinates are recalculated until the errors of the position coordinates are within the preset error range.
