Abstract: A communication procedure for providing or receiving communication parameters can be performed by an easy operation even between devices having both a base station function and a slave station function. A communication device of the present invention determines a role of a device when performing a predetermined communication procedure for providing or receiving communication parameters, and selects operating as a base station or operating as a slave station based on the determined role. The communication device selects based on the determined role operating as a providing device or operating as a receiving device.

Abstract: A communication apparatus creates a network, assigns information necessary for performing communication in the created network to each of other communication apparatuses which have joined the network, and searches for a communication apparatus having a specific service function. Upon completion of assignment of the information necessary for performing communication in the created network, the communication apparatus starts the search.

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.

Abstract: A communication device includes a reception unit, first and second determination units, and a transmission unit. The reception unit receives a search request signal transmitted from another communication device. The first determination unit determines whether the communication device executes a specific protocol. The second determination unit determines whether information indicating the specific protocol is added to the received request signal.

The first execution unit performs a first process for setting a wireless parameter, based on information obtained from a captured image. The setting of a wireless parameter is performed between the communication apparatus and another communication apparatus that operates as an access point and that is different from the communication apparatus. The second execution unit performs, based on information obtained from a captured image, a second process for setting a wireless parameter to another communication apparatus that operates as a station and that is different from the communication apparatus. The wireless parameter is one for performing wireless communication with an access point. The selecting unit selects whether the first process or the second process is to be performed, in a case where information is obtained from a first captured image.
