Mobile communication terminal and method for performing automatic incoming call notification mode change
View Patent ↗A mobile communication terminal is disclosed that allows an incoming call notification mode to be automatically changed depending on an ambient noise signal level, thus eliminating the need to manually change the incoming call notification mode. A microphone capable of automatically changing an incoming call notification mode according to a noise signal level is provided and the terminal stores at least one reference noise signal level; drives the microphone according to a set automatic incoming call notification changing mode to measure a perceived noise signal value; compares the measured noise signal value with the stores reference noise signal level; and sets an incoming call notification mode of the mobile communication terminal to one of a bell mode and a vibration mode according to the result.

a controller for setting the vibration mode if the measured noise signal value is determined to fall within a first noise region according to a comparison by the noise signal level comparator,
wherein the plurality of reference noise signals includes a lower reference noise signal value lower than an upper reference noise signal value, and
wherein the first noise region comprises measured noise values less than the lower reference noise signal and measured noise values greater than the upper reference noise signal value.
2. The terminal of claim 1 , wherein the controller drives the audio processor at time intervals of a predetermined duration.
3. The terminal of claim 2 , wherein the predetermined duration is five seconds.
4. The terminal of claim 1 , further comprising a communication unit for receiving an external incoming call signal,
wherein, upon receipt of an incoming call from the communication unit, the controller drives the audio processor.
5. The terminal of claim 1 , wherein the controller sets a bell mode if the measured noise signal value is determined to fall within a second noise region according to the comparison by the noise level comparator, wherein the second noise region comprises measured noise values greater than the lower reference noise signal value or less than the upper reference noise signal value.
6. The terminal of claim 1 , further comprising a communication unit for receiving an external incoming call signal,
wherein the controller, upon reciept of an incoming call from the communication unit, processes the incoming call according to a set vibration mode.
