<P>PROBLEM TO BE SOLVED: To obtain a communication system capable of efficient network operation and network management using network flexibility with which the combination of a base station with an access node can be arbitrarily set. <P>SOLUTION: When a position registration request is made from a mobile station 100 through a base station 130 and an access node 140 selected by the base station 130, an AAA/HSS 200 determines appropriateness of the access node 140 about the accommodation of the mobile station 100, on the basis of a database managed by the AAA/HSS 200 (step S5). On determining that an access node 150 is to accommodate the mobile station 100, the AAA/HSS 200 instructs the base station 130 to make the position registration request again through the access node 150, so as to change an access node to accommodate the mobile station 100. <P>COPYRIGHT: (C)2013,JPO&INPIT |
