Abstract:
A communication apparatus includes a participation unit, a formation unit, a management unit, and a notification unit. The participation unit participates in a first network formed by a first base station. The formation unit forms a second network as a second base station. The management unit manages a power mode of another communication apparatus participating in the second network. Moreover, when the participation unit participates in the first network and the formation unit forms the second network, the notification unit notifies the first base station of a change of a power mode of the communication apparatus according to the power mode managed by the management unit.
Abstract:
In a communication apparatus on a network where communication apparatuses perform direct communication with each other, a network management apparatus for managing the network based on message information transmitted and received on the network is determined. When the communication apparatus itself is determined as the network management apparatus, the apparatus collects information indicating device capabilities from other communication apparatuses. On the other hand, the communication apparatus receives information indicating device capabilities from another communication apparatus when the other communication apparatus is determined as the network management apparatus.
Abstract:
If frequency band (channel) expansion is made without careful consideration, communications of other apparatuses are disturbed. An apparatus which belongs to an identical network before expansion of the frequency band may no longer be able to make a communication after expansion of the frequency band. To accomplish this, upon making communications using a plurality of channels, a communication apparatus of a network probes the presence of other networks, requests other communication apparatuses of the network to make communication using the plurality of channels based on the probe result, and makes communication using the plurality of channels based on responses to the request. Upon making communications using neighboring channels, the communication apparatus probes the presence of networks in neighboring channels and channels that neighbor the neighboring channels, and makes communications using a used channel and the neighboring channel.
Abstract:
A communication device is provided having wireless capabilities configured to communicate in a first communication mode via an access point and in a second communication mode directly between other communication devices without utilizing an access point. The communication device includes a detecting unit configured to detect the existence of an available wireless network; a receiving unit configured to receive a request from another communication device for transferring communication parameters in the second communication mode; and a transmitting unit configured to transmit communication parameters relating to the available wireless network to the other communication device in response to the request.
Abstract:
A device capability attribute regarding a setting on communication parameters, and provision attribute information indicative of whether or not a communication terminal is in a state that it can provide communication parameters to another communication terminal are stored in advance. The communication terminal, where the device capability attribute has at least a provision capability of the communication parameters, is selected as a provision device. In a case where there are plural communication terminals where the device capability attribute has a communication parameter provision capability, a communication terminal where the device capability attribute has the communication parameter provision capability only is preferentially selected. In a case where the device capability attributes of respective communication terminals are equal, a communication terminal storing the provision attribute information indicative of the state that it can provide the communication parameters is selected as a provision device.

Abstract:
A method of making a management apparatus that manages a wireless parameter of a wireless network formed by a base station set the wireless parameter in a wireless communication apparatus, comprising the steps of causing the base station to request the management apparatus to start a wireless parameter setting process when a start of wireless parameter setting is designated in the base station, causing the management apparatus to notify the base station of wireless parameter setting information containing wireless parameter setting start enable/disable information when the management apparatus receives the request from the base station, causing the base station to notify the wireless communication apparatus of the wireless parameter setting information received from the management apparatus, and causing the wireless communication apparatus to execute or stop the wireless parameter setting process for a wireless setting apparatus based on the wireless parameter setting information received from the base station.

Abstract:
A communication apparatus determines whether another communication apparatus participating in a network established in accordance with a first communication standard is also compatible with a second communication standard. The communication apparatus detects leaving of the network by another communication apparatus incompatible with the second communication standard. The communication apparatus establishes a network that adheres to the second communication standard, depending on the detection result.
Abstract:
To reduce the processing load and maintain higher security in the communications, a communication apparatus includes a network surveying unit configured to determine at least one of (1) an architecture of a network comprising the communication apparatus, and (2) the number of apparatuses on the network; and an alteration detecting unit configured to perform alteration detection processing on data packets received by the communication apparatus, the processing being based on the determination by the network surveying unit.
