Abstract: To facilitate account information setting, in a communication system including a management apparatus which manages account information to be used to use a service provided by a server apparatus, and a user apparatus which uses the service, the management apparatus selects, based on device classification information acquired from the user apparatus, account information to be provided to the user apparatus from one or more pieces of account information stored in a storage unit, and provides the account information to the user apparatus. The user apparatus sends the device classification information of the user apparatus to the management apparatus, receives, from the management apparatus, the account information selected based on the device classification information, and uses the service provided by the server apparatus.

Abstract: A wireless terminal which newly joins a wireless communication system transmits a message containing its identification data to an access point in the wireless communication system at a communication parameter setting start. Upon receiving the message, the access point determines whether or not the wireless terminal has been registered. If it is determined that the wireless terminal has not been registered, the access point determines whether or not the wireless terminal is a setting target device of communication parameters based on the identification data contained in the message. If it is determined that the wireless terminal is a setting target device, the access point sets communication parameters for the wireless terminal.

Abstract: When a connection is made to a wireless network constructed by a base station, a request to construct a wireless network in which a wireless communication apparatus operates as a base station is sensed and a determination is made as to whether communication is in progress with a communication apparatus of a network different from the wireless network constructed by the base station. If the request to construct the wireless network is sensed and it is determined that communication is in progress with a communication apparatus of a network different from the wireless network in which the base station is the intermediary, then an attempt is made to construct a wireless network in which the wireless communication apparatus operates as a base station.

Abstract: A communication apparatus detects network information concerning a network that communicates via a base station and performs acquisition processing for acquiring authentication information used for authentication with an authentication server via the base station from another communication apparatus according to the network information detected by the detection unit.

Abstract: When an instruction operation given by a user to start communication parameter setting is detected, an operation mode of a communication device is determined. According to the determined operation mode, it is determined whether to provide a communication parameter through another communication device operating in a base station mode, or provide a communication parameter directly by the communication device.

Abstract: A management apparatus transmits a registration message to a base station when executing a wireless parameter setting sequence. The base station registers the management apparatus upon the detection of the message. This makes it possible to decrease unwanted communication traffic, and to reduce the time taken to perform the wireless parameter setting processing.

Abstract: A communication system includes a plurality of terminals and a management device that manages a plurality of networks. A first terminal, which is connected to a first network to which the management device is also connected, transmits a connection request for connecting to a second network to the management device. Upon receiving the connection request, the management device determines a predetermined topology from among a plurality of topologies that can be formed when the first terminal connects to the second network. The first terminal receives network configuration information indicating the predetermined topology from the management device. The first terminal transmits the network configuration information to a plurality of terminals participating in the second network. The second network is recreated accordingly.

Abstract: When a communication apparatus transmits data to another communication apparatus, a network connected to the communication apparatus and a network connected to the other communication apparatus are searched for. It is determined, in accordance with a communication channel decided based on the search result, whether to execute encryption of the data to be transmitted. If it is determined to execute the encryption, the data is transmitted after encrypting at least part of it.

Abstract: To set communication parameters, a communication apparatus identifies a communication parameter setting wireless network on the basis of a network identifier provided in itself. If the communication apparatus can identify any network identifier matching the network identifier provided in itself, it sets the communication parameters in cooperation with another communication apparatus in the wireless network. If no identifier can be identified, the communication apparatus switches the setting of the communication parameters to a manual operation.

Abstract: Communication between apparatuses is performed by switching an operation mode or a communication mode in the apparatuses based on an encryption method to be used for communication between the apparatuses. For example, in the case that two communication apparatuses are communicating with each other in a first communication mode using a first encryption method, if a request to change to a second encryption method is issued, one communication apparatus switches its operation mode, whereby the communication apparatuses communicate in a second communication mode.
