Abstract

La présente invention se rapporte à un procédé pour le traitement d'un message de radiomessagerie. Elle se rapporte également à un contrôleur de station de base correspondant. Le procédé selon l'invention comprend les étapes suivantes : un contrôleur de station de base reçoit un message de radiomessagerie dans lequel la cible du message de radiomessagerie est un terminal ; le contrôleur de station de base enregistre le message de radiomessagerie quand il détermine que le terminal est dans un processus où il est en train d'établir un flux de blocs temporaires (TBF) sur la liaison descendante avec le contrôleur de station de base ; une fois que l'établissement du flux de blocs temporaires sur la liaison descendante est accompli, le contrôleur de station de base envoie le message de radiomessagerie au terminal. La présente invention permet d’améliorer le taux de réussite dans le domaine de la radiomessagerie.
