SYSTEM AND METHOD FOR IDENTIFYING THE POSITION OF MOBILE TERMINALS

摘要

The present invention relates to a system (10) and method for identifying the position of cellular telephones (12) in a geographical area served by a mobile telephony network (14). The system (10) comprises a mobile location center (15) capable of analyzing information about the electromagnetic (RF) field transmitted by cellular telephones (12) with 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 telephones (12) as a function of probalilistic 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.
