Mobile node for discovering neighbor networks in heterogeneous network environment and network discovery method

摘要

A network discovery method in a heterogeneous network environment. The network discovery method includes receiving neighbor information indicating neighbor PoAs from a MIIS entity at a mobile node that includes a plurality of communication interface sections capable of communicating with different networks; checking at least one neighbor PoA using the neighbor information at the mobile node; and activating a communication interface section corresponding to the checked neighbor PoA at the mobile node. Accordingly, the neighbor networks can be discovered under the heterogeneous network environment and unnecessary power consumption can be avoided.
