Abstract
A mobile device may be operable to receive historical location trail information of a building. A location of the mobile device within the building may be determined by placing, moving or snapping a reference location of the mobile device onto a trail according to the received historical location trail information. The historical location trail information may be acquired from a location server. The historical location trail information stored in the location server may be generated using a plurality of location samples that are provided by one or more other mobile devices that have been within the building. The historical location trail information may also be acquired from an indoor map of the building that is used by the mobile device for navigation within the building. The determined location of the mobile device may then be utilized by the mobile device to navigate within the building for location-based services.
