Abstract
A system and method for controlling layer(L) handover of a mobile node is disclosed. A mobile Internet protocol (MIP) network includes a plurality of mobile nodes, a plurality of users, a plurality of routers, and a handover control system. The plurality of routers periodically report state information of a plurality of base stations and the plurality of routers to a handover control system, which receives the state information to produce a handover topology map and maps a current location of the plurality of mobile nodes to the handover topology map to search for a plurality of target routers having a highest probability of handover. The handover control system transmits the state information of the searched target routers to the mobile nodes. Thus, the Lhandover time can be shortened to tens of ms or less, allowing for seamless real-time multimedia service even though a terminal moves.
