ENVIRONMENT RESPONSIVE MOBILE COMMUNICATION DEVICE OPERATION

摘要

A parameter of a mobile telephone operation, such as type of ringtone and/or ringtone volume, is changed upon determination that the mobile telephone is within an enclosed container or environment such as a briefcase, a purse, a pocket, or the like. Near field communication technology is utilized to detect proximity of the telephone within the enclosure. The parameter of the mobile telephone may also be changed upon determination that the telephone is in a noisy environment such as a crowded room or stadium.
