Paging area forming method in a mobile IP packet communication system, mobility management node and program |
摘要 |
<p>Provided is a mobility management node capable of forming a paging area, without need for management of a migration history at a mobile node and for notification of a migration history from a mobile node to a network. In mobility management node (MAP) 1, mobility manager 66 lets binding cache 68 store a home address and a c/o address of each mobile node (MN) in correlation with each other. Migration history storage 70 stores a transition frequency of the c/o address stored in binding cache 68 in correlation with prefixes before and after transition. Migration history storage 70 defines paging area information by a set of prefixes included in combinations containing common prefixes, out of combinations of prefixes before and after transition with each of which a transition frequency over a predetermined reference value is correlated. Paging controller 72 notifies the MN of this paging area information. <IMAGE></p> |
