1. A method for positioning based on heterogeneous networks, the method comprising:
estimating a position of a personal mobility device (PMD) based on a first wireless signal;
determining whether the PMD is within an intermediate area between a first area and a second area based on the estimated position of the PMD;
determining whether the PMD moves to the second area by using the first wireless signal and a second wireless signal; and
determining the position of the PMD by using any one of the first wireless signal and the second wireless signal based on a movement of the PMD to the second area,
wherein determining the position of the PMD includes:
determining the position of the PMD based on the second wireless signal when it is determined that the PMD has moved to the second area; and
determining the position of the PMD based on the first wireless signal when it is determined that the PMD has not moved to the second area.
