Zusammenfassung:	A technique is disclosed, according to which a race condition between a PMIPv6 binding by a PBU message of PMIPv6 and a CMIPv6 binding by a BU message of CMIPv6 can be resolved. MN 200 has a plurality of radio communication interfaces, and a first interface is connected to MAG 220 of a home PMIPv6 domain 230, for instance. In case the connection of a second interface is changed from MAG 221 of a home PMIPv6 domain to AR 222 of a CMIPv6 domain 231, a BU message 262 is transmitted from the second interface to LMA/HA 250, and identification information of this BU message is notified to MAG from the first interface. By adding time information to this identification information and by transmitting it to LMA/HA, MAG can identify transmission time of the BU message (i.e. relative order with the other messages) from this time information.
