A method for deciding a handover of a mobile terminal based on context information in a network environment includes receiving context information from the terminal and networks; evaluating selection priorities of network interfaces for each transmission path for each application program based on the context information; and obtaining a handover decision value for selecting a best network interface from among the networks by applying a cost function to the evaluated selection priority. Further, an apparatus for deciding a handover of a mobile terminal based on context information in a network environment, includes a monitor that collects context information from the terminal and networks; an analyzer that evaluates selection priorities of the networks for each transmission path for each application program based on the context information; and a planner that obtains a handover decision value for each transmission path of each application program based on the selection priorities.
