Abstract

Disclosed are a method and an apparatus for controlling an alarm function of a mobile device with an inertial sensor. In one example of the method, after an initial threshold value is established, an alarm occurrence is generated at a predefined hour. If the alarm occurrence is the first, an alarm control unit detects a first movement of the mobile device due to the alarm occurrence through the inertial sensor, and adjusts the initial threshold value according to the first movement. If the alarm occurrence is not the first, the alarm control unit detects a second movement of the mobile device through the inertial sensor, compares the second movement with the adjusted threshold value, and stops the alarm occurrence if the second movement is greater than the adjusted threshold value.
