Abstract

L'invention porte sur un système mobile de télécommunications et le procédé associé permettant de déterminer les relations entre des cellules situées dans une aire comportant des cellules non voisines. L'invention recourt à des codages relativement forts d'identificateurs, de stations de base, de trames inactives substantiellement synchronisés, et à des canaux de contrôle d'émission qui sont transmis dans les créneaux temporels reconnus de différences cellules de co-canal à l'intérieure d'une même aire. L'invention permet également de déterminer efficacement et fiablement le relations cellulaires et les informations de synchronisation pour permettre d'améliorer le système.
