| 20090092068 | COMMUNICATION SYSTEM, COMMUNICATION APPARATUS, AND COMMUNICATION METHOD - In an ad hoc mode based on IEEE802.11 standard, when a wireless terminal performs a power save operation to create a network, and a network identifier identical to that of the network to be created is present, the wireless terminal does not join the network. When the wireless terminal is to join the network, and the network identifier identical to that of the network which the wireless terminal is to join is not present, the wireless terminal does not join any network. In this method, reliable connectivity can be obtained in the ad hoc mode which is not defined in the IEEE802.11 standard in detail. | 04-09-2009 |
| 20090196200 | COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, AND NETWORK ESTABLISHING METHOD - 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. | 08-06-2009 |
| 20100061325 | ALLOCATION OF A SECONDARY BAND TO EXPAND THE CAPACITY OF A PRIMARY BAND IN A WLAN 802.11 SYSTEM - 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. | 03-11-2010 |
| 20100182956 | COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, AND METHOD FOR SETTING COMMUNICATION PARAMETERS OF THE COMMUNICATION APPARATUS - 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. | 07-22-2010 |
| 20100195589 | WIRELESS PARAMETER SETTING METHOD, BASE STATION, MANAGEMENT APPARATUS, CONTROL METHOD, AND COMPUTER PROGRAM - 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. | 08-05-2010 |
| 20110058220 | COMMUNICATION SYSTEM, COMMUNICATION APPARATUS, AND COMMUNICATION CONTROL METHOD - In implementing data transfer using noncontact close proximity transfer, the user operability is improved. The invention includes a communication system having a DSC and printer. Each of the DSC and printer includes a noncontact close proximity transfer function unit which executes, when the DSC and printer are located within a communicable range, connection processing for establishing a connection state in a first communication layer, a print image transfer processing unit which executes, when the connection state in the first communication layer is established, authentication processing for checking whether a connection state in a second communication layer has been established, and executes, when authentication fails, connection processing for establishing the connection state in the second communication layer, and a link control unit which transfers data when authentication succeeds or when the connection state in the second communication layer is established. | 03-10-2011 |
| 20110115923 | DIGITAL CAMERA CONNECTED TO A COMPUTER USING RFID AUTHENTIFICATION - A wireless communication apparatus having a first wireless communication unit for performing RFID communication and a second wireless communication unit for performing data transfer executes authentication processing by providing authentication information using communication by the first wireless communication unit, and detects the result of authentication processing. Data transfer using the second wireless communication unit is allowed if authentication success is detected by the authentication processing, and supply of power for the second wireless communication unit is stopped if authentication failure is detected. | 05-19-2011 |
| 20110134819 | COMMUNICATION APPARATUS BELONGING TO A PLURALITY OF NETWORKS, METHOD FOR CONTROLLING THE SAME, AND PROGRAM - 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. | 06-09-2011 |
