A multiple mode terminal according to an exemplary embodiment of the present invention includes a mode controller, an application service unit, a common link module, and a plurality of device drivers. The mode controller uses network state monitoring information and controls the handoff between a plurality of networks. The application service unit includes protocols providing appropriate data communication services for the plurality of networks, and a plurality of programs designed to perform data communication services. The common link module performs the handoff between the heterogeneous networks by a handoff request of the mode controller, updates a transmission path of the data packet according to the performed handoff, and supports a data communication service of the application service unit. The plurality of device drivers control the terminal to function for the data service in the plurality of networks.
