Abstract: Locating mobile stations used for wireless communications even when the mobile station is within a building includes determining whether at least one indicator associated with a signal used by the mobile station identifies a single, known building location. Example types of indicators include a base station and sector identifier of a base station sector dedicated to a particular building, a delay associated with a radio frequency signal used by the mobile station when communicating from a particular building location or a combination of cell codes reported by a mobile station when it is within a particular building location. One or more of such indicators provides an indication of a building location from which the mobile station has placed a call. That building location can then be used as the determined mobile station location.
