Mobile communication system and mobile communication method

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.

Problems solved by technology

[0022] As the number of devices 10 increases, the following problems arise: (1) time and labor are required for creating a list; (2) there is a high possibility of making a mistake when creating a list; 10 It takes time and labor to retrieve the device 10 in a huge list when performing communication; and (4) There is a high possibility of setting errors when setting the attribution address obtained from the list in the personal computer 30

[0030] When delivering the device 10 to the user, the device provider also delivers the product stored in the external storage device 50 that records the serial number and the attribution address of the device 10 associated with each other, if the user purchases a large number of devices 10 , the user therefore owns as many external storage devices 50 as the number of devices 10, so it is very complicated for the user to manage these external storage devices to manage multiple devices
