Abstract

La présente invention concerne un procédé et un système de réduction des zones mortes dans un système de télécommunication mobile de troisième génération (UMTS). Lorsqu'une station mobile SM en communication avec une station de base SB1 engendre des zones mortes sur les liaisons montantes d'une station de base SB2, on définit selon l'invention des critères sur la liaison montante et/ou la liaison descendante entre la station mobile SM et la station de base SB1 qui, si l'un ou l'autre ou les deux ne sont pas respectés, déclenche une procédure d'échec radio dans la station mobile SM. La communication entre la station mobile SM et la station de base SB1 est alors suspendue. La puissance émise sur la liaison montante par la station mobile SM devient alors nulle et la dégradation de la couverture radio de la cellule de la station de base SB2 due à la station mobile SM disparaît.
