Abstract

La présente invention concerne, dans un dispositif de radiolocalisation par chevauchement de réseaux pour un réseau de communications GSM ou UMTS, la possibilité d'utiliser de façon bien plus efficace le spectre par une synchronisation des stations de base, ce qui peut nécessiter une répartition d'un signal de synchronisation à toutes les stations de base, ou l'installation d'un module de synchronisation satellitaire sur chaque site. L'invention propose donc une architecture dans laquelle des modules de mesure pour localisation ou 'LMU' (Location Management Units) sont installées sur certains au moins des sites de stations de base de façon à localiser les dispositifs radio. Les LMU servent à mesurer par diverses techniques de localisation la temporisation de certains signaux remontants et/ou descendants dans le réseau cellulaire. Ces LMU peuvent comporter un module de référence de synchronisation à base de GPS, pouvant servir à synchroniser les bases de temps de tous les LMU. Pour réduire le coût d'ensemble de la synchronisation des stations de base, le LMU distribue des signaux de synchronisation, comprenant une impulsion électrique périodique ainsi qu'une information de description de synchronisation, par une interface série ou autre, disponible pour que d'autre noeuds puissent l'utiliser aux fins de synchronisation. Le format de l'impulsion électrique et de l'information de description de synchronisation est modifié par le logiciel et le matériel de façon à s'adapter au divers formats demandés par les différents types de stations de base. Ainsi, les stations de base à LMU en co-situation peuvent recevoir un signal de synchronisation sans grande exigence matérielle. L'interface externe ou 'EIU' (External Interface Unit) de l'invention permet également de s'adapter aux divers formats matériels des stations de base. Pour les sites de stations de base non équipés de LMU, on peut utiliser un module de chronométrage ou 'TMU' (Timing Measurement Unit). Ce module sert uniquement à fournir à la station de base des signaux de synchronisation dans les mêmes formats que ceux fournis par les LMU. Les signaux de chronométrie fournis par les TMU sont synchrone avec les signaux fournis par les LMU. Un tel TMU uniquement chronomètre coûte moins cher que le LMU parce qu'il est dégagé des fonctions de mesure du signal remontant ou descendant. Cette logique de fonctionnement permet à l'opérateur cellulaire de synchroniser les stations de base à un coût relativement faible.
