METHODS AND APPARATUS FOR MOBILE STATION LOCATION ESTIMATION

摘要

Methods and apparatus for estimating mobile station location include receivi ng reported signal strengths or other attachment indicator values from a mobile station. The reported signal strengths are compared with characteristic received signal strength values in a coverage area of a mobile network. A mobile switching center determines if a location function is requested and initiates a location estimation process by a mobile location module (MLM). T he MLM receives the reported signal strength contours associated with the attachment points. Based on a comparison of the reported attachment indicato r values with characteristic values, the MLM provides a mobile location estima te.
