APPARATUS AND METHOD FOR WIRELESS COMMUNICATION
First Claim
1. A wireless communication apparatus which can simultaneously conduct communication on at least two frequency channels, comprising:
- a notification unit which makes a notification of an identifier of a second frequency channel and a communication system on a first frequency channel, the second frequency channel being in a wireless packet receivable state other than the first frequency channel, the communication system being used on the second frequency channel;
a connection management table in which a communication system is retained along with an identifier of a wireless communication terminal and identifiers of frequency channels, the identifiers of the frequency channels including at least an identifier of the first frequency channel, the communication system being able to be used by the wireless communication terminal and notified by the wireless communication terminal when connection of the wireless communication terminal is permitted on the first frequency channel; and
a communication unit which refers to the connection management table to determine the communication system which can be used by the wireless communication terminal using the identifier of the wireless communication terminal, and conducts communication with the wireless communication terminal on the second frequency channel using the communication system, when a request from the wireless communication terminal to change the first frequency channel to the second frequency channel is permitted.
