Process for analyzing traffic localization within a cellular radiocommunication network

Claim 1

Process for analysing the localization of traffic supported by a given base station of a cellular radiocommunication network, each mobile station served by said given base station periodically transmitting to said given base station measurement samples each including values of a radio parameter measured by said mobile station relative to said given base station and to several neighbouring base stations identified among a predetermined set of base stations neighbouring said given base station, the process including the steps of: gathering measurement samples received by said given base station; processing the gathered measurement samples in such a way as to produce a processed sample of p data groups from each measurement sample emanating from a mobile station, each data group including an identifier of one of the neighbouring base stations of said predetermined set and a measurement datum dependent on a value of the radio parameter measured by the mobile station relative to the identified neighbouring base station, the data groups of each processed sample being ordered such that a group of rank i (1≦i≦p) corresponds to the i-th largest value of the radio parameter measured relative to the neighbouring base stations of the set; distributing the processed samples into categories, each category being associated, for each integer i lying between 1 and p, with a pair of rank i constituted by an identifier of a base station of said predetermined set and by an interval of variation, a processed sample being assigned to a category when, for each integer i lying between 1 and p, on the one hand the base station identifier of the data group of rank i of said processed sample coincides with the base station identifier of the pair of rank i associated with said category, and on the other hand the measurement datum of the data group of rank i of said processed sample falls within the interval of variation of the pair of rank i associated with said category; associating respective geographical zones with some at least of the categories on the basis of mapping data of the radio parameter; and estimating traffic densities within said geographical zones on the basis of the numbers of samples assigned to the associated categories.
