摘要： A technique is disclosed, by which it is possible to achieve the reduction of power consumption of each wireless node and to perform efficient access control in wireless communication system. According to this technique, a given period with a beacon transmitted from a gateway (GW) 100 at the foremost position is divided to an active period where each wireless node (P2P tag) transmits and receives a frame and a sleep period where transmitting and receiving of the frames are stopped. Further, the active period is divided to a plurality of timeslots each with a fixed length, and the period is partitioned to sub-periods where each type of a GW, a fixed node (P2P-S tag), and a mobile node (P2P-M tag) can transmit frames respectively. Each of the P2P tags selects a timeslot at random from the period for each type, and after waiting for a waiting period at random at the selected timeslot, it transmits a frame including information to identify the selected timeslot or the waiting period in addition to its own ID.

摘要： Disclosed is a technique to prevent a collision in a state that radio communication devices are congested. According to the technique, in the state that the radio communication devices are congested, one of the radio communication devices becomes a representative node and transmits a representative node advertisement message. When the representative node has received a data packet after transmission of the representative node advertisement message, it transmits a response confirmation message. When a radio communication device, which was not decided as the representative node, has become a normal node and received the representative node advertisement message, it transmits a data packet. Then, when receiving a confirmation message after transmission of the data packet, the radio communication device stops data packet transmission during the next active period.

摘要： A technology for providing an access network system that can reduce the load of a connection authentication of a connection to an access network, upon dividing authentication into the connection authentication of the connection to the access network and a connection authentication of a connection to an external IP network, is disclosed. According to the technology, a first base station device 104a and a second base station device 104b are included. The first base station device is connected to a mobile node 101. The first base station device receives a first authentication request from the mobile node, transmits the first authentication request to an authentication device 102, and receives a first authentication result from the authentication device. The second base station device is newly connected to the mobile node by movement of the mobile node after the mobile node and the first base station device are connected. The second base station device receives a second authentication request including identifying information of the first base station device from the mobile node and transmits the second authentication request to the first base station device. Upon receiving the second authentication request, the first base station device transmits the first authentication result to the second base station device.
