A system and method are provided for determining the location or position of a mobile station (MS) within a digital wireless network when only two base stations are available for time of arrival or other triangulation measurements. A call setup is initiated concurrently with the gathering of timing advance or other such location data on the targeted MS, thereby allowing cell sector information to be collected. This data, along with the locating data, is then reported to a Master Positioning Center where distance calculations are made from the locating data. Positional ambiguities are then resolved with a comparison to the serving cell identity recovered during the call placement to the mobile when the locating data was being taken.
