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 apparatus performs wireless connection processing for performing wireless communication with another communication apparatus, specifies a service that is to be executed along with the other communication apparatus, in the wireless connection processing, using wireless communication that is based on the wireless connection processing, and performs port control such that a port necessary for execution of the specified service is opened, and a port not necessary for execution of the service is locked.

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: A communication apparatus includes a detection unit and a display control unit. The detection unit detects a network. The display control unit causes a display unit to display information. In a case where information about a provider providing a network is not obtained from the network detected by the detection unit, the display control unit causes the display unit to display identification information about the network. In a case where information about a provider providing the network is obtained from the network, the display control unit causes the display unit to display information about the provider instead of causing identification information about the network to be displayed.
