ABSTRACT:
Annunciator apparatus, and an associated method, for a mobile station, such as a radio telephone operable in a cellular communication system. When a call is to be terminated at the mobile station, a determination is made of the ambient noise levels proximate to the mobile station. Responsive to the determinations of the ambient noise level, selection is made of the loudness level of the ringing tone to be generated by an annunciator, used to annunciate the terminating call. Thereby, the loudness level of the ringing tone generated by the annunciator is of a loudness level appropriate for the conditions at which the mobile station is positioned.
