A mobile communication terminal comprising:

• a radio frequency part for communicating with at least one base station;
• an interface unit for inputting/outputting a voice from/to a hands-free microphone/speaker;
• an input unit for receiving a mode command for activating/deactivating a speakerphone mode and for receiving a call command for making a call to a far-end user or answering a call made from the far-end user;
• and
• a controller for transmitting information related to the speakerphone mode to the at least one base station using a radio frequency part via a reverse access channel before a traffic channel for a voice transfer is opened between the mobile communication terminal and another mobile communication terminal.

A mobile communication terminal comprising:

• a radio frequency part for communicating with at least one base station;
• a microphone/speaker for inputting a voice of a first user and for outputting a voice of a second user;
• an output unit for outputting an alert message;
• a memory for storing a mapping table;
• and
• a controller for mapping a received message based on a speakerphone mode information by referring to the mapping table when the radio frequency part receives the message via a forward paging channel from the at least one base station before a traffic channel for a voice transfer is opened between the first user and the second user, the controller outputting the alert message by the output unit based on the speakerphone mode information.
