Apparatus and method of enabling to transceive data using a plurality of heterogeneous networks selectively through a fixed host address

Abstract

The mobile communication terminal capable of accessing to a plurality of heterogeneous networks selectively, according to the present invention, comprises a process which communicates data with an application running on the mobile communication terminal, through a local socket created with its destination address set to a fixed internal address; and another process which creates at least one outward socket by setting its source address to an IP address assigned from one of the plurality of heterogeneous networks and its destination address to a remote address, and communicates data with an outside server of the remote address through the at least one outward socket. Data communication is made between the local socket and the at least one outward socket if the at least one outward socket is set as associated with the local socket.
