  • Patent number: 9420415
    Abstract: A first node selects a selection node that is the send source of a packet with the highest received radio wave intensity from among packets received from a plurality of second node. The first node sends, to the selection node, a report packet that stores therein an identifier that specifies each of a plurality of first nodes and whose destination is a third node. The second node adds an identifier that specifies each of the plurality of second nodes to the report packet that was received from the first node with the received radio wave intensity that is equal to or greater than a predetermined value among the report packets which are transmitted by the plurality of first nodes and relays the report packet to the third node. The third node detects a node corresponding to the identifier that is not included in the report packets received.

  • Patent number: 9118537
    Abstract: A reception apparatus includes a receiver configured to receive a packet including a label and quality information indicating communication quality for the packet. The reception apparatus also includes a processor configured to allocate a priority to the received packet based on a combination of the label and the quality information included in the received packet and a transmitter configured to supply the packet to which the priority is allocated to a switch that performs transfer control to a packet based on its priority.

  • Patent number: 6996411
    Abstract: A wireless communication terminal including a wireless communication unit for receiving and transmitting voice signals between terminals connected through a voice channel and a data channel, a signal input/output unit for inputting and outputting voice signals for voice communication and a mixing unit, interposed between the wireless communication unit and signal input/output unit, for performing mixing operations to create a first mixed signal to be output to said signal input/output unit and second mixed signals each to be transmitted to the corresponding terminal. The wireless communication terminal is preferably used for wireless voice communication performed by three or more terminals without being interposed by a center apparatus (such as a server) or a repeater. Further, signal-receiving/transmitting is set for each wireless communication terminal whereupon convenience can be improved.
