<p>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.</p> |
