description PROBLEM TO BE SOLVED: To provide a mobile IP data communication system in which a packet addressed to a mobile station can be prevented from missing when switching a packet control station with movement of the mobile station without particularly requiring a special function more than packet control station switching itself for the mobile station in the mobile IP data communication system wherein the packet control station relays IP data communication connection between the mobile station and an access router. SOLUTION: A packet on IP data communication connection used by a mobile station is transferred from the moving source packet control station of the mobile station to a moving destination packet control station. Processing for buffering a packet which reaches the moving destination packet control station from the access router during transfer and first passing the transfer packet or processing for transferring the packet before the packet is delivered from the access router is performed, thereby keeping right the order of packets.
