A relay gateway device includes a processor and a storage, in which when a packet transmission is performed between a first mobile device and a second mobile device and the second mobile device switches from the relay gateway device to another, the IP address of the second mobile device changes from a former IP address to a current IP address. When the first mobile device transmits a first packet to the second mobile device in which the destination address of the first packet is the former IP address, the processor of the relay gateway device modifies the destination address of the first packet into the current IP address according to the former IP address and the current IP address of the second mobile device in a list of the storage and then transmits the first packet to the second mobile device, thereby achieving a seamless transmission during handover.
