摘要： Aspects of the disclosure provide a method for positioning data management. The method includes checking a reset condition that is used to trigger a reset of boundaries of signal strength values for clustering a group of positioning data associated with a wireless station into subsets. Each positioning data associates position information of a location with an identifier of the wireless station for providing wireless connection at the location and a strength of a signal received at the location. Further, the method includes updating, when the reset condition is satisfied, one or more boundaries to re-allocate the group of positioning data in order to increase a population uniformity across the subsets, and storing the updated boundaries.
