A mobile node stores a binding update message and an AMR message in the header of an IPv6 packet, and transmits the packet to a home agent. This packet is once transferred to an AAAH. The AAAH authenticates the mobile node according to the AMR message, stores the binding update message and a service profile of the mobile node in the header of the IPv6 packet, and transmits the packet to the home agent. The home agent registers the location of the mobile node, stores the service profile in the header of the IPv6 packet, and transmits the packet to the mobile node.
