Abstract

La présente demande concerne un procédé de communication sans fil et un appareil de communication. Le procédé consiste : à recevoir un message de demande provenant d'un terminal, le message de demande demandant l'enregistrement auprès d'un SNPN ; à acquérir des informations GIN, les informations GIN étant les informations GIN utilisées par le terminal lors de la sélection du SNPN ou d'une liste GIN dans des informations de diffusion cellulaire de la cellule qui a été accédée par le terminal ; à déterminer si des informations d'abonnement du terminal prennent en charge les informations GIN, les informations d'abonnement comprenant une liste GIN préférée qui a une priorité et qui est contrôlée par un CH ; et à rejeter le terminal s'enregistrant auprès du SNPN si les informations d'abonnement du terminal ne prennent pas en charge les informations GIN. Selon la solution décrite, le côté réseau rejette un terminal s'enregistrant auprès d'un SNPN si le côté réseau détermine que les informations d'abonnement du terminal ne prennent pas en charge des informations GIN relatives au terminal, ce qui permet d'empêcher le terminal d'accéder de manière erronée au SNPN et d'obtenir en outre, sur la base des informations GIN, une commande d'accès sur le terminal.
