1. A mobile communications terminal comprising:
- a keypad having a plurality of touch keys and touch sensor units for sensing key inputs received from touching of the plurality of touch keys, and outputting a key input signal according to a sensed key input; and
a controller detecting key input signals corresponding to two or more of the plurality of touch keys input via the keypad within a predetermined time interval, determining a priority for each of the plurality of the touch keys, and recognizing one of the two or more of the plurality of touch keys as a key input according to the determined priority,wherein the controller;
determines a task which is currently being performed;
identifies a first touch key among the plurality of touch keys that is not related to the task currently being performed;
identifies a second touch key among the plurality of touch keys that is related to the task currently being performed;
adjusts a sensitivity level of the first touch key to be lower than a sensitivity level of the second touch key;
detects a key input signal corresponding to each of the plurality of touch keys; and
determines a touch key having a highest sensitivity level corresponding to the detected key input signal as the key input.

Abstract
A mobile communications terminal and a method for preventing an input error of a key input unit are provided. The mobile communications terminal includes a touch sensor unit for sensing a key that is input by touching a keypad region in order to output a key input signal corresponding to the key and a controller adapted to determine a key input according to either a priority between multiple keys from which key signals are received or whether a received key signal was generated inadvertently.
