A technology is disclosed for providing a packet transfer control method that can transmit a DU message to a specific CN or a specific flow to prompt a change in destination, while maintaining a transfer request to a CoA from a HA. In the technology, when a home agent receives a packet addressed to a mobile terminal from a predetermined communication terminal, the mobile terminal transmits a second message to the home agent, the second message including information required for the home agent to transmit a first message to the predetermined communication terminal. The first message states that a currently used address addressed to the mobile terminal cannot be used. The home agent generates the first message based on the information included in the second message and transmits the generated first message to the predetermined communication terminal.
