Abstract

Un mode de réalisation de la présente invention concerne le domaine technique des communications, et concerne un procédé et un dispositif permettant d'établir une connexion, ce qui peut résoudre le problème selon lequel un équipement d'utilisateur (UE) est incapable d'exécuter un service urgent en raison de l'état d'enregistrement de l'UE. Le procédé comprend les étapes suivantes : un UE, qui est situé dans une zone spécifiée, envoie un message de demande de service (SR) à une fonction de gestion d'accès et de mobilité (AMF); l'AMF reçoit le message de SR qui est envoyé par l'UE, et, après avoir déterminé que l'UE se trouve dans la zone spécifiée, l'AMF établit une connexion de signalisation de strate de non-accès (NAS) avec l'UE selon des informations d'indication; après l'établissement de la connexion de signalisation de NAS, l'AMF envoie un message de SA à l'UE; l'UE reçoit le message de SA qui est renvoyé par l'AMF, et démarre un processus d'établissement de session d'unité de données de protocole (PDU). La zone spécifiée comprend une zone interdite et/ou une zone non autorisée, et le message de SR transporte les informations d'indication, les informations d'indication servant à ordonner à l'UE d'envoyer le message de SR afin de démarrer un service urgent. Si le message de SR est remplacé par un message d'ESR, le message de SA qu'envoie l'AMF à l'UE est également remplacé en conséquence, de façon à être un message de rétroaction correspondant au message d'ESR. La solution proposée par le mode de réalisation de la présente invention convient pour être utilisée lorsqu'un terminal établit une connexion.
