Abstract

A dual-mode mobile terminal, which can access synchronous and asynchronous mobile communication systems, includes a key input panel and a controller. The key input panel includes a call switching key for switching between calls from the two systems and a call end key for ending calls from the two systems. While the terminal performs communication of one call received from one of the two systems in a general communication mode over a communication channel currently established by the one system, the controller determines whether an incoming call is received from the other system. If the incoming call is received, the controller notifies the user of receipt of the incoming call. If the call switching key is pressed, the controller prepares a communication environment for communication of the incoming call, allowing the user to perform the communication of the incoming call while maintaining the currently established communication channel.
