Abstract

La présente invention concerne le domaine de la technologie des communications et, plus particulièrement, un procédé, un appareil et un système de traitement de message de diamètre. Les modes de réalisation de la présente invention concernent un procédé de traitement de message de diamètre, selon lequel la fonction commande de session d'appel (CSCF) détermine si le message de diamètre à transmettre à un serveur d'abonné résidentiel (HSS) est un message de tête de diamètre et, si tel est le cas, la CSCF transmet un message de diamètre avec une identification de message de tête au HSS. Par l'application du procédé des modes de réalisation de l'invention, lors de la réalisation d'un processus de surcharge, le HSS peut reconnaître si le diamètre reçu est un message de tête de diamètre; la charge du processus que le HSS réalise lors du processus de surcharge est alors réduite.
