Abstract
A mobile communication system includes a mobile terminal, a radio access network, and a home agent. The radio access network includes a radio base station which carries out packet communication with the mobile terminal through a radio channel, and a radio channel control station which controls the radio base station. The home agent stores data transmitted from said mobile terminal and associated with a current position of said mobile terminal. The packet communication between the mobile terminal and the radio channel control station is controlled based on radio channel control of packet switching connection. The packet communication from the core network to the radio channel control station is controlled based on mobile IP (mobile Internet Protocol).
