<P>PROBLEM TO BE SOLVED: To provide a communication system which can perform efficient operation and management of a network by using the flexibility of the network which can freely set up a combination of a base station and an access node. <P>SOLUTION: When a request for position registration is sent from a mobile station 100 to a base station 130 via an access node 140 selected by the base station 130, AAA/HSS200 judges the appropriateness for the access node 140 accommodating the mobile station 100 based on the database managed by its self-device (step S5). When the AAA/HSS 200 determines that an access node 150 should accommodate the mobile station 100, it instructs the base station 130 to send a request for position registration once again via the access node 150, and thereby changes the access node which accommodates the mobile station 100. <P>COPYRIGHT: (C)2008,JPO&INPIT |
