Abstract
The present invention relates to a systemand method for identifying the position of cellular telephonesin a geographical area served by a mobile telephony networkThe systemcomprises a mobile location centercapable of analyzing information about the electromagnetic (RF) field transmitted by cellular telephoneswith reference information including both RF information and probabilistic information associated with the morphology of the geographical area. The method involves assigning different weights to the location of cellular telephonesas a function of probabilistic reference information, and thus makes it possible to use statistical methods for resolving situations of ambiguity in locating cellular telephones which would otherwise be resolved in purely random fashion.
