Mobile communication network system and mobility managing unit |
摘要 |
<p>A mobile communication network system (1) is disclosed. The network system comprises a transport network (30) including a plurality of routers (31), and a network control apparatus (20) for controlling mobility of a mobile node (40, MN1), characterized in that the network control apparatus (20) comprises a mobility managing unit (LRM1) for managing information (CDT) of a correspondent node (41, MN2) communicating with the mobile node (40, MN1); the mobility managing unit (LRM1) comprises a boundary router detecting unit for detecting that the mobile node (MN1) moves and reaches a boundary of a router (AR2) managed by the mobility managing unit (LRM1) itself; and a correspondent node information forwarding unit for forwarding the information (CDT) of the correspondent node (MN2) to a neighbor mobility managing unit (LRM2) having a similar structure, when it is detected that the mobile node (MN1) reaches a boundary of a router (AR2) managed by the mobility managing unit (LRM1) itself.
