METHOD AND SYSTEM FOR IDENTIFYING INTERFERENCE SOURCES IN A TELECOMMUNICATIONS NETWORK
(FR)
PROCEDE ET SYSTEME PERMETTANT D'IDENTIFIER DES SOURCES D'INTERFERENCES DANS UN RESEAU DE TELECOMMUNICATIONS
Abstract:
(EN)
A method and system for determining sources of downlink interference in a telecommunications network having offending cells and disturbed disposed therein. Initially, mobile traffic events in offending cells within the telecommunications network are identified. Disturbance events in disturbed cells within the telecommunications network are also determined. The identified mobile traffic events are then correlated with the identified disturbance events in order to detect possible sources of disturbance within the telecommunications network. A disturbance distribution for each disturbed cell within the telecommunications network is thereafter computed, when all identified mobile traffic events are correlated with the all identified disturbance events, thereby enabling network engineers to optimize the telecommunications network by minimizing downlink interference. The method and system are thus based on measurements and not predictions, so that the measurements take into account the behavior of all mobiles within the telecommunications network rather than a particular mobile event.
(FR)
L'invention concerne un procédé et un système permettant d'identifier des sources d'interférences sur le trajet descendant dans un réseau de télécommunications pourvu de cellules fautives et de cellules perturbées à l'intérieur même du réseau de télécommunication. Initialement, les événements de trafic d'un mobile intervenant dans les cellules fautives contenues à l'intérieur du réseau de télécommunications sont identifiés. Les événements de perturbation intervenant dans les cellules perturbées contenues à l'intérieur du réseau de télécommunications sont également déterminés. Les événements de trafic d'un mobile identifiés sont mis en corrélation avec les événements de perturbation identifiés de manière à détecter des sources éventuelles de perturbation à l'intérieur du réseau de télécommunication. Lorsque tous les événements de trafic d'un mobile identifiés sont mis en corrélation avec tous les événements de perturbation identifiés, une répartition de la perturbation pour chaque cellule perturbée contenue dans le réseau de télécommunications est calculée; ceci permet aux ingénieurs de réseau d'optimiser le réseau de télécommunications en minimisant les interférences sur le trajet descendant. Ainsi, le procédé et le système sont fondés sur des mesures et non sur des prévisions, de sorte que les mesures tiennent compte du comportement de tous les mobiles à l'intérieur du réseau de télécommunications plutôt que d'un événement de mobile isolé.
