Abstract

La présente invention concerne un procédé et un appareil permettant la déviation d'un message. Ledit procédé se déroule de la manière suivante : si la surveillance indique qu'un centre de traitement de SMS est encombré, les informations d'émission mobiles (MO) transmises à un centre de traitement de SMS lors de la surveillance de la granularité sont déviées selon un système de déviation prédéfini. Ledit appareil comprend un module de surveillance et un module de déviation. La présente invention permet d'obtenir une déviation automatique d'un service, ce qui offre rapidement et en toute sécurité aux opérateurs une solution efficace et peu coûteuse au problème de l'augmentation soudaine du trafic rapide.
