Abstract

An access gateway (GW) receives, from a mobility management node, a transmission-path control signal for changing a route of only part of a data packet flow that pertains to a mobile terminal and is originally relayed through the access GW and a first mobility anchor. In response to receiving the transmission-path control signal, the access GW establishes a logical transmission path with a second mobility anchor for transferring the part of the data packet flow, and transfers the part of the packet flow to the second mobility anchor and also transfers a remaining part of the packet flow to the first mobility anchor by distinguishing a data packet received from the mobile terminal.
