PROBLEM TO BE SOLVED: To provide a wireless communication apparatus such as a wireless communication apparatus adopting the PDC system capable of selecting either of voice communication and a packet communication, for execution, which prevents the communication with a packet communication destination from being terminated even when the wireless communication apparatus permits the arrival of the voice communication during the packet communication.SOLUTION: When the mobile phone terminal (wireless communication apparatus) 1 permits the arrival of voice communication from a phone terminal 3 of a third party through a line exchange communication network 2 during the packet communication with an application processing apparatus 5 through a packet switch communication network 4, mobile phone terminal 1 outputs a hold signal for interrupting the processing associated with the packet communication to the application processing apparatus 5 via the packet switch communication network 4 and releases the hold signal when the voice communication ends. Thus, the packet communication is not terminated, but suspended so that the time up to the communication end can be reduced. Further, only by transferring the data uncompleted after the restart, the communication charge and unnecessary traffic can be suppressed.
