Abstract

In a communication control method for wireless communication between a first communication device and a second communication device through a wireless communication unit, identification information is notified from the second communication device to the first communication device by using a communication unit other than the wireless communication unit. Wireless communication between the first and second communication devices is performed by the wireless communication unit using the first communication parameter shared in advance, and authentication processing based on identification information is performed. When authentication is acquired by this authentication processing, the second communication parameter to be set with respect to a wireless communication unit is shared by the first and second communication devices through the above wireless communication. Parameters for wireless communication between the first and second communication devices are set in the wireless communication unit by using the second communication parameter shared in this manner.
