PROBLEM TO BE SOLVED: To provide a communication terminal apparatus and a control method capable of reducing communication disabled time.SOLUTION: A smart phone 1 includes: a first communication processing part 31 for performing wireless communication by a WiMAX; a second communication processing part 33 for performing the wireless communication by a CDMA; and a control part 30 for controlling each communication processing part in an order that the first communication processing part 31 performs data communication followed by the data communication of the second communication processing part 33. The control part 30 continues, if a radio wave strength of the WiMAX becomes below a breakdown threshold value while connecting with the WiMAX, connection to the WiMAX by the first communication processing part 31 and also starts connecting processing to the CDMA by the second communication processing part 33. |
