Abstract
A pass-through packet determination unit (112) of an anchor GW 100A controls whether or not to transfer a Layer 3 packet arriving from an external network (20) to a downlink channel set up with a mobile terminal (700) based on a transfer policy. Further, a transfer policy control unit (111) changes the transfer policy to enable transfer of a multicast packet or a broadcast packet to the mobile terminal (700) by the downlink channel in response to receiving from the mobile terminal (700) a Layer 3 packet preliminarily specified as a trigger to start transfer of a multicast packet or a broadcast packet to the mobile terminal (700) by the downlink channel.
