CONSTITUTION: An IP(Internet Protocol) mobility protocol is constructed between an integrated gateway, which supports binding with mobile terminal and heterogeneous network, and one or more base stations and on a stream control transmission protocol(SCTP) layer of an interface protocol used between the base stations. The IP mobility protocol creates a signaling message for binding with the mobile terminal and network. The stream control transmission protocol layer includes at least one part of the signaling message in order to create a stream control transmission protocol packet. A binding update request or update result of the mobile terminal and the network is transceived through the stream control transmission protocol packet.
