First Claim
1. A wireless communication apparatus which includes a communication unit that can simultaneously conduct communication on at least first and second frequency channels, comprising:
- a notification unit which transmits, via the communication unit on the first frequency channel, a notification of a first communication system, an identifier of the second frequency channel, and a notification of a second communication system, the first communication system being used on the first frequency channel, and the second communication system being used on the second frequency channel;
a decision unit which decides whether or not to permit a connection request from a wireless communication terminal, decides whether or not to permit a frequency channel change request for changing to the second frequency channel from the wireless communication terminal, when the connection and change requests are received via the communication unit, generates a response to each of the connection and change requests, and transmits the response via the communication unit; and
a connection management table in which a third communication system is retained along with an identifier of the wireless communication terminal and an identifier of the second frequency channel, the third communication system being;
able to be used by the wireless communication terminal on the second frequency channel,notified by the connection request received via the communication unit on the first frequency channel, andretained when the connection request is permitted by the decision unit, wherein the communication unit refers to the connection management table to determine the third communication system which can be used to communicate with 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 third communication system, when the frequency channel change request is permitted by the decision unit.

Abstract
A wireless communication apparatus which can simultaneously conduct communication on at least two frequency channels is described. The apparatus includes a communication unit which refers to a connection management table to determine a communication system which can be used by a wireless communication terminal using an identifier of the wireless communication terminal, and conducts communication with the wireless communication terminal on a 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.
