METHOD OF PERFORMING HANDOVER USING SUBNET INFORMATION AND APPARATUS THEREFOR

摘要

A method and an apparatus for performing handover using subnet information are provided to determine whether to perform handover of an upper layer and a lower layer by directly using subnet information. A sub-net information comparing unit(120) compares sub-net information related to a current connection point and sub-net information related to a new connection point. A layer determining unit(140) determines a layer in which handover will be performed according to whether the sub-net information related to the current connection point and the sub-net information related to the new connection point are identical or not. A message transmission unit(150) transmits a message for performing handover to the determined handover performing layer. A sub-net information receiving unit(110) receives the sub-net information related to the new connection point from an information server.
