A system and method for controlling layer 3 (L3) handover of a mobile node. A mobile Internet protocol (MIP) network includes a plurality of mobile nodes adapted to provide data service to a plurality of users, and a plurality of routers and a handover control system, the plurality of routers being adapted to provide data service to ones of the plurality of mobile nodes in coverage areas of a plurality of base stations managed by the plurality of routers, and to periodically report state information of the plurality of base stations and the plurality of routers to a handover control system, the handover control system being adapted to receive the state information of the plurality of base stations and the plurality of routers to produce a handover topology map, to map a current location of ones 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 of ones of the plurality of mobile nodes, and to transmit the state information of the searched plurality of target routers to the ones of the plurality of mobile nodes. Thus, the L3 handover time can be shortened to tens of ms or less, allowing for seamless real-time multimedia service even though a terminal moves.
