More Information
Summary:The subject matter disclosed herein relates to a method for estimating the location of a mobile station. The method comprises identifying the locations of a serving cell and at least one other landmark proximate to said mobile station based, at least in part, on accessing a database maintained at said mobile station comprising location information of said at least one other landmark, and determining an initial estimate of the location of the mobile station based, at least in part, on the identified locations of the serving cell and the at least one other landmark. Processing of one or more satellite positioning system (SPS) signals is based, at least in part, on said initial estimate.
