摘要 |
The present invention implements an intermittent reception method with which a portable station that does not receive a multicast service does not enter the Awake state unnecessarily. A packet buffer portion buffers a received packet in such a memory as RAM and recording device, and judges whether the buffered packet is a multicast packet. When the packet buffer unit judges that the packet buffered by the packet buffer unit is a multicast packet, a DTIM beacon generation unit generates a DTIM beacon in which multicast notification data indicating that the multicast packet is buffered is set. A packet transmission unit transmits the DTIM beacon generated by the DTIM beacon generation unit to wireless communication stations or the like. |
