1. An information processing apparatus comprising:
- a wireless communication unit which is constructed to wirelessly communicate with another communication apparatus by a direct link and by an indirect link via a control apparatus;
a sending unit constructed to send a probe signal which includes identification information of a network established by the control apparatus, in response to receiving a request for setting of a communication channel from a first communication apparatus during communication with a second communication apparatus by the indirect link;
a receiving unit constructed to receive directly from a communication apparatus a response signal sent by the communication apparatus based on the identification information included in the probe signal;
a determination unit constructed to determine a communication apparatus that is able to communicate with the information processing apparatus by the direct link, based on the response signal received by the receiving unit; and
a switch unit constructed to switch the indirect link with the second communication apparatus to a direct link with the second communication apparatus, in the case that the determination unit determines that the second communication apparatus is able to communicate with the information processing apparatus by the direct link.

12. A control method for an information processing apparatus, said control method comprising the steps of:
-
wirelessly communicating with another communication apparatus by a direct link and by an indirect link via a control apparatus; sending a probe signal which includes identification information of a network established by the control apparatus, in response to receiving a request for setting of a communication channel from a first communication apparatus during communication with a second communication apparatus by the indirect link; receiving directly from a communication apparatus a response signal sent by the communication apparatus based on the identification information included in the probe signal; determining a communication apparatus that is able to communicate with the information processing apparatus by the direct link, based on the response signal received in the receiving step; and switching the indirect link with the second communication apparatus to the direct link with the second communication apparatus, in the case that the determining step determines that the second communication apparatus is able to communicate with the information processing apparatus by the direct link. - View Dependent Claims (13)
