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 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.

The present invention relates to a system 10 and corresponding method for locating mobile terminals 12 following a location request whereto is associated information whose content depends on the position and characteristics of the mobile terminal 12 to be located. The system 10 comprises a cellular phone location centre (MLC centre) 15 able to locate the mobile terminals 12, in selective fashion, as the type and reliability of the received information vary. The system 10 and corresponding method allow, by means of the MLC centre 15, to select, among a plurality of location engines, a determined engine suited to manage the received information and selectively to identify both the position of the mobile terminal 12 and accuracy indicators relating to the type of locating operation performed.

摘要:
The system allows determining whether at least one terminal belongs to a target space in a communications network in order to provide a set of services linked to the fact that the terminal belongs or does not belong to the above target space. The belonging is determined depending on at least one determination parameter. The services are associated with, preferably through a model, respective service specifications indicating the allowable error margin in determining whether the terminal belongs or does not belong to the target space. The determination parameters are changed depending on the above service specifications.
摘要:
The field received starting at least one source of electromagnetic field in a determined position of the territory covered by a communication network has a plurality of field sources estimated on the basis of a propagation model. The model in question is modified, for example, in parametric fashion according to the topology of said field sources. Preferential application to locating mobile terminals, in particular in view of the provision of services based on location.
