摘要： Provided are a device and method for performing handover by detecting a state of another wireless network when only a wireless access interface for a current access network is activated in a mobile terminal. A handover controller performs communication between a mobile terminal performing a single radio handover and an information server managing access information for each wireless network.

摘要： A method and system for reducing transmission route of packet in Internet based nested mobile network are provided. In the method, a plurality of routers in an Internet based nested mobile network register location information using a top-level mobile router. Then, each of the mobile routers creates NEMO routing information. A packet is received through own home agent using the location information registered at the top-level router in the nested mobile network when a terminal in the outside of the mobile network transmits a packet. The receive packet is processed through the created NEMO routing information at the top-level router.
