A communication device which provides a service to a service utilizing device which utilizes a service, determines whether or not the communication device is executing a service requested from the service utilizing device. In the case where it is determined that the communication device is executing the service, the communication device makes a response to the request with the contents of the response changed according to whether or not the service is able to be provided to a plurality of service utilizing devices.

Abstract: A communication apparatus functioning as a master device denies participation by new communication apparatuses in a network in communication parameter configuration mode based on participation statuses of communication apparatuses functioning as slave devices in the network. The communication apparatus functioning as a master device establishes the network in communication parameter configuration mode between the communication apparatuses participating in the network, and configures communication parameters.

Abstract: A communication apparatus determines whether the communication apparatus is to operate as a transmission apparatus for transmitting service data to be transferred by a service performed via a network, or operate as both the transmission apparatus for transmitting the service data to be transferred by the service performed via the network and a reception apparatus for receiving the service data to be transferred by the service performed via the network, terminates a connection with a communication partner apparatus in response to completion of transmission of the service data if the communication apparatus operates as the transmission apparatus, and terminates the connection with the communication partner apparatus in response to a user operation if the communication apparatus operates as both the transmission apparatus and the reception apparatus.

Abstract: A communication apparatus operating as an access point on a network receives a signal transmitted by a communication apparatus on the network, transfers the signal to another communication apparatus on the network, and transmits, in response to a request signal, a response signal containing function information of the communication apparatus operating as the access point to a transmission source communication apparatus of the request signal on the network, which has transmitted the request signal. The communication apparatus controls transfer so that the transmission source communication apparatus of the request signal receives no response signal from a communication apparatus other than the communication apparatus operating as the access point on the network.

Abstract: A communication apparatus starts short distance wireless communication with another communication apparatus while joining a wireless LAN created by an external access point (AP) as a station, determines whether the communication apparatus can concurrently perform a station function and an AP function of the wireless LAN in accordance with the start of the short distance wireless communication, directly connects to the other communication apparatus by the wireless LAN by disconnecting from the external AP when it is not determined that the station function and the AP function can be concurrently performed, reconnects to the external AP as the station when the direct connection fails, and directly connects to the other communication apparatus by the wireless LAN without disconnecting from the external AP when it is determined that the station function and the AP function can be performed concurrently.

Abstract: When a wireless network is constructed, a wireless communication apparatus in the wireless network constructed of a plurality of communication apparatuses decides whether to function as a providing source of communication parameters or as a provision destination that receives communication parameters. In a case where it has been decided that this apparatus is to function as the provision destination that receives communication parameters, the apparatus requests authentication when it participates in the wireless network using communication parameters. In a case where it has been decided that this apparatus is to function as the providing source of communication parameters, the apparatus execute authentication processing in response to an authentication request.

Abstract: A communication apparatus in which a service can more efficiently used is provided. The communication apparatus searches for an apparatus that provides a particular service and establishes a wireless connection to the other searched communication apparatus. Subsequently, an address of the other connected communication apparatus is obtained from the other communication apparatus, and the service provided by the other communication apparatus is used using the obtained address.
