Method and apparatus for automatically changing a call receive mode in a mobile terminal

An apparatus for automatically changing a call receive mode in a mobile terminal, the apparatus comprising:

• an external environment sensor configured to sense an external illumination level and noise level, and a position coordinate;
• a schedule reference unit configured to manage a schedule;
• a mode use history unit configured to manage a use history of a call receive mode;
• and
• a controller configured to:
• perform a first process to identify a current external illumination level and noise level through the external environment sensor and, according to the identified external illumination level and noise level, identify a first preset execution suitability of each call receive mode,
• perform a second process to identify a current user schedule through the schedule reference unit and, according to the identified schedule, identify a second preset execution suitability of each call receive mode,
• perform a third process to identify a current position coordinate through the external environment sensor and determine an execution suitability corresponding to a use ratio of previous usage of each call receive mode within a predetermined radius range starting from the identified position coordinate,
• perform a fourth process to identify a previous use history of each call receive mode from the mode use history unit and determine a current execution suitability of each call receive mode, and
• perform a fifth process to determine an integrated execution suitability of each call receive mode from results acquired in one or more of the first to fourth processes and select the call receive mode having the highest integrated execution suitability.
