Summary:The subject matter disclosed herein relates to a system and method for reducing an initial position uncertainty of a mobile station. In one example, although claimed subject matter is not so limited, a process to improve an initial position estimate comprises identifying the locations of a serving cell and at least one other landmark proximate to a receiver and determining an initial estimate of the location of the receiver based, at least in part, on the identified locations of the serving cell and the at least one other landmark.. L'invention concerne un système et un procédé pour réduire l'incertitude de position initiale d'une station mobile. Dans un exemple, bien que le sujet revendiqué ne soit pas limité, un procédé pour améliorer l'estimation de position initiale comporte l'identification des emplacements d'une cellule de desserte et d'au moins un autre point de repère proche d'un récepteur et la détermination d'une estimation initiale de l'emplacement du récepteur en fonction, au moins en partie, des emplacements identifiés de la cellule de desserte et d'au moins un autre point de repère.
