COMMUNICATION APPARATUS
First Claim
1. A communication apparatus capable of connecting to one of a plurality of relay apparatuses that relays wireless communications, the communication apparatus comprising:
- an identification-data storage unit that stores therein first device identification data for identifying a first relay apparatus to which the communication apparatus is currently being connected, the first device identification data being unique to the first relay apparatus;
a transmitting unit that transmits a request message that requests connectable relay apparatuses to return a response message;
a receiving unit that receives response messages from the connectable relay apparatuses, each of the response message including individual device identification data of the relay apparatus that transmitted the request message;
a determining unit that determines whether received request message includes the individual device identification data that matches with the first device identification data stored in the identification-data storage unit; and
a connection requesting unit that requests, if no received response message includes the individual device identification data that matches with the first device identification data stored in the identification-data storage unit, a second relay apparatus from among the relay apparatuses identified by second device identification data that is included in any of the received response messages to make a connection with the communication apparatus.

Abstract
A communication apparatus transmits a request message to connectable relay apparatuses, and receives a response message from the relay apparatuses. The communication apparatus determines whether the received request message includes the device identification data of a relay apparatus to which it is currently connected. If no received response message includes the device identification data of a relay apparatus to which it is currently connected, the communication apparatus requests another relay apparatus identified based on device identification data that is included in any of the received response messages to make a connection with the communication apparatus.
