Abstract

Dans son mode de réalisation, la présente invention se rapporte à un procédé et à un dispositif de traitement d'appel dans une réserve de centres de commutation de communications mobiles (MSC, Mobile Switching Center). Le procédé selon l'invention comprend les étapes suivantes : une entité de gestion de la mobilité (MME, Mobility Management Entity) reçoit un message de demande d'appel envoyé par un MSC/VLR (Visitor Location Register, enregistreur de localisation des visiteurs) d'une réserve de MSC. Ledit message de demande d'appel contient une identité internationale d'abonné mobile (IMSI, International Mobile Subscriber Identity) d'un équipement d'utilisateur (UE, User Equipment) mais ne contient pas une identité d'abonné mobile temporaire (TMSI, Temporary Mobile Subscriber Identity) dudit UE. Ladite MME envoie la TMSI dudit UE ou une S-TMSI dudit UE audit UE, dans le but d'amener ledit UE à envoyer, audit MSC/VLR, un message de réponse à la demande d'appel par le biais d'un BSS/RNS, ledit message de réponse à la demande d'appel contenant le message de demande de TMSI dudit UE.
