Abstract: A specific unit in a first wireless communication device determines whether a second wireless communication device is a priority candidate device based on the possibility that the connection with the second wireless communication device will be disconnected. When a communication control unit receives a permission request for a communication with the second wireless communication device from a connection control unit, it grants a permission to a communication with a “priority candidate device”.
