    摘要： In the power save mode of an IEEE 802.11 adhoc network, a packet loss occurs unless the power save state of a receiving side is detected, failing in communication. However, there is no explicit notification on joining/leaving in/from a network, and it is difficult to detect and manage the state of a partner, including the detection timing. To solve this problem, a terminal always transmits an information notification packet (ATIM packet) in a time during which all terminals can receive it, prior to data transmission regardless of the power save state of a partner. With this mechanism, the terminal also explicitly notifies the partner of a change in the power save state of the terminal.

    摘要： Power saving cannot be implemented in the adhoc mode by only the IEEE 802.11 standard. This is because communication partners mutually utilize the power save mode in the adhoc mode, and their states must always be managed. In the adhoc mode, the number of communication partners is not always one, and all stations which join a network are candidates, increasing the load of implementation. To solve this problem, a communication apparatus notifies a change to power save mode by an ATIM packet, RTS packet, or null packet. When the ATIM packet or RTS packet is transmitted, the communication apparatus can notify the partner of a change in mode regardless of whether the partner is in the power save mode. When the null packet is transmitted, the communication apparatus can rapidly notify the partner without waiting for any beacon.

    摘要翻译： 只能通过IEEE 802.11标准在adhoc模式下实现省电。 这是因为通信伙伴在adhoc模式下相互利用省电模式，并且必须始终管理其状态。 在adhoc模式中，通信伙伴的数量并不总是一个，加入网络的所有站都是候选的，从而增加了实现的负担。 为了解决这个问题，通信装置通过ATIM分组，RTS分组或空分组来通知节电模式的改变。 当发送ATIM分组或RTS分组时，无论对方是否处于省电模式，通信装置都可以向对方通知模式改变。 当发送空分组时，通信装置可以在不等待任何信标的情况下快速通知对方。

    摘要： An information communication device has a storage medium that stores information to determine a target information communication device on a network. A selection unit selects at least one protocol from plural protocols for obtaining information on other information communication devices on the basis of the stored information. A generating unit generates a list of information communication devices that have the at least one selected protocol as target information communication devices which a user can select on the network.

    摘要： In a communication apparatus for wirelessly communicating directly with a communication apparatus that is participating in a network, a filter is set so as to receive only a signal from a communicating party before start of a power-saving control function at the time of standby, the set filter is removed after the power-saving control function for standby is terminated, and a logical address on the network is reset. As a result, when the power-saving control function is utilized, collision of physical addresses is prevented and it is possible to perform data communication without mismatch.
