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.

A dual-mode mobile terminal that connects to synchronous and asynchronous mobile communication systems and a method for displaying accurate time information in the terminal. The terminal includes a timer and a controller. The timer generates an interrupt signal at a predetermined time. When entering an asynchronous communication mode, the controller starts the timer to generate the interrupt signal at the predetermined time. When receiving the interrupt signal from the timer, the controller connects to the synchronous mobile communication system to obtain accurate time information therefrom and then connects to the asynchronous mobile communication system to switch to the asynchronous communication mode.

Disclosed are an apparatus and a method for controlling reverse TX power in a mobile terminal. The apparatus includes a closed-loop power controller for limiting a TX power increase due to a power control bit of an RX signal by using a power-up limit bit and outputting a closed-loop power control value for decreasing the TX power when a TX power limit mode is selected, an adder for calculating a TX power by adding the closed-loop power control value and an open-loop power set using a power of the RX signal, and a maximum TX power limiter for setting a final TX power by subtracting a maximum TX power limit reference value determined according to an RX signal strength in the mobile terminal from the calculated TX power. Accordingly, it is possible to extend a call duration while accepting a rather poor call quality.
