<p>When a position registration from a mobile terminal to 2nd subscriber profile management means of an exchange unit is demanded, the position registration is performed from the 2nd subscriber profile management means to 1st subscriber profile management means of a home position registration unit, and a subscriber profile is not transferred from the 1st subscriber profile management means to the 2nd subscriber profile management means. Accordingly, a transfer of the subscriber profile from the home position registration unit to the exchange unit is reduced, so that an increase in traffic can be prevented.</p> |
