Process for analyzing traffic localization within a cellular radiocommunication network
First 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.

Abstract
In order to analyze the localization of the traffic supported by a base station of a cellular radio communication network, the process exploits the measurements of radio parameters made by the mobile stations with regard to the base station and to neighboring base stations. Statistical processing of these measurements makes it possible, with the aid of mapping data of the measured parameter, to determine the traffic densities within the cell, at least in zones of heavy traffic density. These results allow the operator of the network to select the best places to install new base stations, especially for microcells.
