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.

摘要： When a wireless communication station, which is about to communicate while intermittently receiving a multicast service, transmits, to an access point, a request packet describing information on the multicast service and an intermittent reception request, the access point describes, in a packet, intermittent reception timing information corresponding to the multicast service information described in this request packet, and replies with this packet to the wireless communication station. The wireless communication station reads the intermittent reception timing information from the received packet, and performs transition to the Awake state or the Doze state according to this intermittent reception timing. The access point, on the other hand, transmits the multicast packet to the wireless communication station according to the intermittent reception timing.
