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： An object of the present invention is to realize a distributed autonomous transmission scheduling by using a terminal without the need to observe packets in relation to communication of other wireless terminals in a cell, such as VoIP, in which a plurality of wireless terminals that periodically transmit packets exist, thereby allowing intermittent reception during the packet observation and enabling to control power consumption of the wireless terminal as well as to reduce the load to thereby improve the communication quality. To attain the object, a VoIP terminal 100 recognizes and retains a scheduling table received by a wireless terminal that is connected to a wireless base station and that is not communicating with other wireless terminals, additionally writes terminal information of the terminal in the scheduling table at the start of communication of the terminal, and broadcasts the scheduling table.
