ABSTRACT:
A muting system (10) according to the present invention enables wireless communication devices (16,18) that enter a silent zone to generate a silent zone advisory message (64) and subsequently mute the wireless communication devices (16, 18). A muting device (14) remotely instructs the wireless communication devices (16, 18) to enter a silent mode. A digital information system (20) maintains muting status information that includes information such as the event description, location, and duration in a categorized formation. The digital information center (20) remotely communicates the muting status information to the wireless communication devices (16, 18) so that the wireless communication devices (16, 18) can generate a silent zone advisory message to communicate the status information to callers while the devices are muted.
