A cellular communication system and method for determining cell relations between cells is disclosed. The cellular communication system transmits signals from one or more transmitters, for example, mobile stations or base stations, over a plurality of radio frequency channels that are assigned to the cells. The transmitted signals over the plurality of radio frequency channels are received at each one of the cells and their received signals strengths are measured at corresponding measurement times. The received signal strength measurements and corresponding measurement times are processed to determine whether a measured received signal strength at a corresponding measurement time is based on a transmission from a single transmitter in a cell. The measurements corresponding to signals found originated from single transmitters are used for determining the cell relations in terms of such parameters as path gain values or C/I ratios.
La présente invention concerne un système et un procédé de communication cellulaire qui permet de déterminer les relations entre cellules. Le système de communication cellulaire transmet des signaux provenant d'un ou de plusieurs émetteurs, par exemple des stations mobiles ou des stations de base, via une pluralité de canaux de fréquences radioélectrique attribués aux cellules. Les signaux ainsi transmis sont reçus sur chacune des cellules, leur intensité étant mesurée aux instants de mesure correspondants. On traite les mesures de force des signaux reçus et les instants de mesure correspondants pour déterminer si la force mesurée du signal reçu à un moment de mesure correspondant est fonction de la transmission par un seul émetteur dans une cellule. Les mesures correspondant à des signaux dont on constate qu'ils proviennent d'émetteurs uniques servent à déterminer les relations intracellulaires en termes de paramètres tels que valeurs de gain sur le trajet ou rapports porteuse/brouillage.
