    Abstract: 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 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.

    Abstract: The present invention relates to a system and method for planning networks for mobile terminals that use a radio interface based on the Code Division Multiple Access or CDMA technique. More particularly, the system and method provide a step 500 whereby the Service Areas in these networks can be calculated using, as a reference, Domains calculated by means of a step 300 on the basis of real propagation models and taking a predetermined or estimated traffic into account on a pixel by pixel basis. In addition, the system and method make it possible to calculate the Macrodiversity Areas by means of a step 700, and thus to take the areas in which mobile terminals are capable of exchanging information with more than one radio base station into account at the planning step.
