## Abstract

A communication apparatus connectable to a communication network notifies the presence of the communication apparatus using a communication channel assigned to the communication apparatus, then sets one communication channel different from the assigned communication channel of those available in the communication network, and searches for a communication partner apparatus which functions as a providing apparatus that provides communication parameters using the set communication channel. The communication apparatus repetitively executes the notification processing and the search processing, and changes a communication channel used in the search processing every time the repetition is executed one or a plurality of number of times.

## Claims

### Claim 1

A communication apparatus connectable to a communication network, comprising:
notification means for notifying the presence of said communication apparatus using a communication channel assigned to said communication apparatus;
search means for setting one communication channel different from the assigned communication channel of communication channels available in the communication network, and searching for a communication partner apparatus which functions as a providing apparatus that provides communication parameters using the set communication channel; and
a control means for controlling said notification means and said search means to alternately repeat the notification processing and the search processing, and changing a communication channel used by said search means every time the repetition is executed one or a plurality of number of times.
first channel and length of period for the wait processing is randomly determined.
wherein, in the share processing, the communication apparatus provides the communication partner apparatus with the communication parameter in accordance with the role determined by the communication apparatus.
partner apparatus.
