When the role of a receiver is not predetermined, it is impossible to uniquely determine the transfer direction of communication parameters. A communication apparatus comprises: discrimination means adapted to discriminate a function of another communication apparatus with respect to communication parameter setting processing when the self communication apparatus is a candidate for a providing apparatus of communication parameters; setting means adapted to set the function of the self communication apparatus as a receiving apparatus of communication parameters upon detecting an apparatus that is confirmed as a providing apparatus of communication parameters before a set time elapses; and execution means adapted, if the setting means sets the function as the receiving apparatus, to execute, as a receiving apparatus of communication parameters, the communication parameter setting processing with the providing apparatus.
