<p>There is provided a technique for ensuring that the order in which a terminal, when performing a three- party handover, receives packets is the same as the order in which a transmitter terminal transmits those packets. When a terminal device successively handovers among a plurality of radio base station routers, a radio base station router serving as an anchor during the handovers buffers packets addressed to the terminal device, and forwards those packets by switching between a tunnel between a radio base station having a cell of which the terminal device moves out and the anchor radio base station and a tunnel between the anchor radio base station and a radio base station having a cell into which the terminal device moves. ® KIPO & WIPO 2007</p> |
