Abstract

L'invention concerne un procédé et un système de déclenchement pour notifier un brouillage coexistant intradispositif. Le procédé comprend les étapes suivantes: une installation d'abonné (UE) détecte un paramètre, configuré par le réseau et destiné à déclencher la notification d'un brouillage coexistant intraterminal et à notifier au réseau le brouillage coexistant intraterminal, quand il est estiné qu'une condition de notification de brouillage préétablie est remplie. L'invention permet de déclencher précisément la notification d'un brouillage coexistant intradispositif.
