Abstract

A mobile communication system includes a home agent which transfers a communication packet to a mobile communication device connected to a foreign network, an address management section which manages a plurality of IP addresses, an address generation section which assigns any of the IP addresses managed, by the address management section to the mobile communication device as a home address thereof, a server which stores the home address of the mobile communication device and specific information of the mobile communication device in association with each other, and a source node which connects with the server through a network, and transmits the communication packet to any mobile communication device having the home addresses stored in the server as a destination.
