PURPOSE: A data communication method using a distribution type structure is provided to solve a problem about extensibility and to improve a speed of a communication service. CONSTITUTION: If a mobile node is newly entered in a network, a data packet from a correspondent node is received(S410). The mobile node transmits a request of mapping data of the mobile node in a multicast method to a plurality of routers in the network(S420). The mobile node receives mapping data of the mobile node from the router connected to the mobile node in a plurality of the routers(S430). The mobile node transmits the data packet received from the correspondent node to the router connected to the mobile node based on the received mapping data of the mobile node(S440). [Reference numerals] (AA) Start; (BB) End; (S410) Receive a data packet from a correspondent node when a mobile node enters a network; (S420) Transmit a request for mapping data of the mobile node with a multicast method to a plurality of routers in the network; (S430) Receive the mapping data of the mobile node from the router connected to the mobile node among the plurality of routers; (S440) Transmit the data packet received from the correspondent node to the router connected to the mobile node based on the received mapping data |
