摘要:
A data transmission/reception path between a server and a mobile terminal in a heterogeneous network environment is controlled by mapping at least one actual Internet protocol (IP) address available to the mobile terminal in the heterogeneous network environment to at least one virtual IP to generate a path mapping table, and determining a data transmission/reception path between the server and the mobile terminal with reference to the generated path mapping table. This virtualization of terminal actual addresses with respect to a server improves service continuity in an efficient, low cost manner, independent of the need to modify the OS kernel in various devices.
