ABSTRACT:
The present invention aims to provide continuous communication, between mobile terminal, based on edge mobility technology, during hand over a mobile terminal, even if addresses of edge routers before/after movement of the mobile terminal may not be acquired from the mobile terminal. It is configured so that when the mobile terminal moves, it becomes connected to the edge router and a CN information request command is transmitted to a home agent. The home agent manages a care-of address corresponding to a home address of the mobile terminal and transmits the CN information request command to this care-of address, which corresponds to the edge router before the mobile terminal moves, and the edge router manages a care-of address of a communication partner of the mobile terminal. Therefore, the care-of address of the communication partner of the mobile terminal can be acquired.
