COMMUNICATION CONTROL METHOD, NETWORK NODE, AND MOBILE TERMINAL

摘要

A technology is disclosed with which a mobile terminal moving in a PMIP domain receives various types of prefixes and selects a type of an address to be configured, and route optimization is performed without adding a signaling load on the PMIP domain. According to the technique, when connecting with a home domain, a MN (310) requests a plurality of prefixes. When a MAG (320) makes an AAA server (340) authorize the MN and receives a notification instruction of the plurality of prefixes from the AAA server, the MAG 320 makes a notification of the plurality of prefixes with a RA message (364), for example. The MN configures a plurality of addresses (for example, a PMIP address including a PMIP domain prefix or a global address including an on-link prefix) from the plurality of prefixes received and notifies the MAG of the same. The MAG registers a plurality of bindings relating to the plurality of addresses with a LMA (330).
