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

摘要

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.

主权项

1. A wireless terminal, comprising:
a first processing unit configured to communicate data with an application running on the wireless terminal through at least one local connection interface having a destination address that is set to an internal address; and a second processing unit configured to communicate the data with a remote computing system through at least one outward connection interface having (1) a source address that is set to an address associated with one of a plurality of heterogeneous networks and (2) a destination address that is set to a remote address; wherein the wireless terminal is configured to communicate data between said at least one local connection interface and said at least one outward connection interface based on an association between such connection interfaces, and wherein if access to one network of the plurality of heterogeneous networks is inhibited, the wireless terminal is further configured to create one or more new outward connection interfaces each having (1) a source address that is set to an address associated with a different network of the plurality of heterogeneous networks and (2) a destination address that is set to said remote address.
