Abstract

L'invention concerne un procédé, un appareil et un système pour la connexion de service d'utilisateur pendant la panne du réseau. Le procédé comprend les étapes suivantes : lorsque l'utilisateur du centre de commutation mobile (MSC) en panne dans le groupe est appelé, le dispositif fonctionnel du groupe transfère le message de recherche de personnes émis par le MSC normal à l'utilisateur; le dispositif fonctionnel acquiert le message de réponse de recherche de personnes renvoyé par l'utilisateur, et achemine le message de réponse de recherche de personnes TMSI au MSC normal dans le cas où le message de réponse de recherche de personnes est le message de réponse de recherche de personnes de l'identité d'abonné mobile temporaire (TMSI). Lorsque l'utilisateur du MSC en panne dans le groupe est appelé, le plan technique ci-dessus peut garantir que la communication efficace est activée lorsque l'utilisateur fait l'expérience du premier service de communication.
