WIRELESS COMMUNICATION TERMINAL APPARATUS AND PROGRAM

摘要

A wireless communication terminal apparatus comprises a radio part that switches between first and second communication systems to perform a wireless communication by use of a shared antenna; and a control part that controls the wireless communication performed by the radio part. The control part monitors the arrival of an incoming call in the second communication system during communication of the first communication system. If detecting that arrival, then the control part switches from the first communication system to the second communication system for a first predetermined time for which the communication of the first communication system is not disconnected. After the first predetermined time elapses, the control part switches from the second communication system to the first communication system to resume the communication of the first communication system.
