LINK CONTROL METHOD IN MULTI-PATH

摘要

PURPOSE: A link control method using multiple paths is provided to obtain communication paths regardless of wireless communication disconnection by utilizing other communication paths. CONSTITUTION: A local mobility anchor(LMA) receives a downlink(DL) message from a correspondent node(CN)(S310). The LMA confirms an uplink(UL) history related to a first communication path or a second communication path from among two or more communication paths and a mobile node(MN) related to DL setup information(S320). The LMA selects one DL from among two or more communication paths for the MN on the bais of the DL setup information and the UL history(S330).
