<p>A method for a handover and a gateway supporting the same is disclosed, which is capable of optimally establishing a data path between a current BS being in contact with an MS and a target ASN-GW as well as a data path between a serving ASN-GW and a home network on the handover between ASNs, wherein the method of the handover between ASNs in the wireless access system after a handover between a previous BS and a current BS by a movement of an MS, comprises, when an ASN-ASN handover request message and first SF Info are transmitted to a target ASN-GW from a serving ASN-GW, establishing a first data path between the target ASN-GW and a home network; transmitting a data path ID of the target ASN-GW to the serving ASN-GW; and establishing a second data path between the current BS and the target ASN-GW through the use of data path ID of the target ASN-GW.</p> |
