CA 2672124

A user device comprises means for identifying the TA of the visited cell on the basis of the report information, judging means for judging whether or not the user device is permitted to carry out communication in a P-NW if the identified TA is for P-NW, and means for transmitting a signal for requesting to update the TA to the one for P-NW to the base station of the visited cell if communication in the P-NW is permitted. The judging means judges whether or not the identified TA is for P-NW by checking common identification information common to P-NWs among information included in the report information, and judges whether the communication is permitted by checking if the P-NW to which the visited cell belongs is the same as the P-NW in which communication by the user device is permitted.

Un dispositif utilisateur comprend des moyens pour identifier le TA d'une cellule visitée sur la base des informations de rapport, des moyens de détermination pour déterminer si ou non le dispositif utilisateur est autorisé à réaliser une communication dans un P-NW si le TA identifié est pour P-NW, et des moyens pour transmettre un signal pour demander de mettre à jour le TA à celui pour le P-NW vers la station de base de la cellule visitée si la communication dans le P-NW est autorisée. Les moyens de détermination déterminent si ou non le TA identifié est pour le P-NW par vérification des informations d'identification communes aux P-NW parmi des informations comprises dans les informations de rapport, et déterminent si ou non la communication est autorisée par la vérification du point de savoir si le P-NW auquel la cellule visitée appartient est identique au P-NW dans lequel une communication par le dispositif utilisateur est autorisée.
